  • The U.S. Is Purging Chinese Americans From Top Cancer Research - Bloomberg
    https://www.bloomberg.com/news/features/2019-06-13/the-u-s-is-purging-chinese-americans-from-top-cancer-research

    In January, Wu, an award-winning epidemiologist and naturalized American citizen , quietly stepped down as director of the Center for Public Health and Translational Genomics at the University of Texas MD Anderson Cancer Center after a three-month investigation into her professional ties in China. Her resignation, and the departures in recent months of three other top Chinese American scientists from Houston-based MD Anderson, stem from a Trump administration drive to counter Chinese influence at U.S. research institutions.

    Prometheus (arbre) — Wikipédia
    https://fr.wikipedia.org/wiki/Prometheus_(arbre)

    Prometheus (également connu sous le code WPN-114) est le surnom d’un pin de Bristlecone (Pinus longaeva) âgé probablement de plus de 5 000 ans et situé dans le Nevada au niveau de l’étage alpin. Il est abattu en 1964 dans le cadre d’une étude de la dynamique des climats du Petit âge glaciaire par dendrochronologie. Il était considéré comme le végétal le plus âgé de la planète jusqu’en 2008 où on a fait la découverte d’un bosquet d’épicéas âgé de 9 550 ans en Suède1, le Old Tjikko.

    Il est abattu le 6 août 1964 par Donald Rusk Currey (en), un doctorant et un membre du Service des forêts des États-Unis à des fins de recherche et alors que son âge n’était pas encore connu. Depuis lors, c’est l’arbre Mathusalem qui est considéré comme le Bristlecone le plus âgé au monde.

    Il doit son nom à Prométhée, qui d’après la Théogonie d’Hésiode, créa les hommes à partir d’une motte d’argile.

    Étude de l’arbre

    Cet arbre appartenait à une population de pins de Bristlecone qui poussent à la limite de l’étage alpin sur la moraine latérale d’un ancien glacier sur le pic Wheeler, où, depuis 1986, se trouve le parc national de Great Basin, dans le Nevada oriental. Le pic Wheeler est la plus haute montagne du Snake Range et la plus haute montagne située entièrement dans l’État de Nevada. La population de pins de Bristlecone qui y pousse se divise en au moins deux sous-populations distinctes, dont l’une est accessible par un sentier d’interprétation très fréquenté. Prometheus pourtant, a grandi dans une région où l’on ne peut se rendre que par des randonnées à pied hors piste. En 1958 ou en 1961, un groupe de naturalistes qui avaient admiré le bosquet où l’arbre avait poussé a donné des noms à un certain nombre d’arbres, les plus grands ou les plus curieux, y compris Prometheus. La désignation comme WPN-114 a été donnée par le chercheur Donald R. Currey et vient du fait que c’est le 114e arbre qu’il a retenu pour ses recherches dans le comté de White Pine au Nevada.

    Le compte des anneaux effectué par Currey sur la section de l’arbre était de 4 844. Quelques années plus tard, il a été porté à 4862 par Donald Graybill, du Laboratoire de recherche sur les cernes des arbres (université d’Arizona). En 2010, Chris Baisan et Matthew Salzer du même laboratoire ont affiné la mesure de l’âge, par interdatation, ce qui permet de tenir compte des anneaux manquants (fréquents dans les arbres poussant à la limite de l’étage alpin). Ils obtiennent 4 900 ans très précisément. Cependant, le compte des anneaux a été fait sur une coupe transversale du tronc prise à environ 2,5 m au-dessus du point de germination original de l’arbre, parce que les anneaux les plus centraux manquaient au-dessous de ce point. En ajoutant les années nécessaires pour atteindre cette hauteur, il est probable que l’arbre ait eu près de 5 000 ans au moment de la coupe. Cela fait de lui le plus vieil organisme unitaire (c’est-à-dire non-clonal) qu’on ait jamais connu, dépassant d’environ 200 ans l’arbre Mathusalem du Bosquet Schulman dans les Montagnes Blanches en Californie.

    Que Prometheus soit considéré ou non comme l’organisme le plus ancien qu’on ait jamais connu dépend de la définition qu’on donne aux termes « le plus ancien » et « organisme ». Par exemple, certains organismes germinatifs ou clonaux, comme un buisson de créosote ou un tremble, pourraient avoir des individus plus âgés si l’organisme clonal est regardé comme un tout. En pareil cas, l’organisme vivant le plus ancien est un bosquet de Populus tremuloides dans l’Utah, connu sous le nom de Pando, avec 80 000 ans. Dans un organisme clonal, pourtant, les pieds clonaux individuels ne sont nulle part et de loin aussi anciens et aucune partie de l’organisme à aucun point dans le temps ne devient particulièrement vieille. Prometheus était ainsi l’organisme non-clonal le plus ancien qui ait été découvert, avec son bois le plus profond qui avait de 5 000 ans d’âge. Il est possible, pourtant, qu’il existe un exemplaire plus ancien dont l’âge n’ait pas encore été évalué. Les pins bristlecones sont connus pour la difficulté qu’on a à évaluer leur âge à cause de leur croissance particulièrement contorsionnée et l’abattage de très vieux arbres n’est plus autorisé.
    L’abattage de l’arbre

    Dans les années 1950 les dendrochronologistes ont fait de grands efforts pour découvrir les espèces d’arbres actuelles les plus anciennes ; ils comptaient utiliser l’analyse des anneaux pour différents objectifs de recherche, comme la reconstitution d’anciens climats, la datation de ruines archéologiques et cette question fondamentale qui est la recherche des créatures actuelles les plus anciennes. Edward Schulman a découvert alors que les pins bristlecones dans les Montagnes blanches de Californie et ailleurs étaient plus vieux que n’importe quelle espèce déjà datée. On a eu donc envie de trouver des bristlecones très âgés, plus âgés peut-être que l’arbre Mathusalem, estimé par Schulman en 1957 à plus de 4700 ans.

    Donald R. Currey était doctorant à l’université de Caroline du Nord à Chapel Hill, et il étudiait la dynamique des climats du Petit âge glaciaire en utilisant les techniques de la dendrochronologie. En 1963 son attention fut attirée par les populations de bristlecones dans le Snake Range, et sur le pic Wheeler en particulier. En se fondant sur la taille, le taux de croissance et les formes de croissance de certains des arbres, il se convainquit qu’il existait sur la montagne quelques exemplaires très anciens et il préleva une carotte sur certains d’entre eux, trouvant des arbres dépassant 3 000 ans. Currey ne réussit pourtant pas à obtenir une série continue de carottages avec chevauchement pour WPN-114. Ici, les histoires divergent. On ne sait pas bien si c’est Currey qui a demandé, ou si c’est le personnel du service forestier qui a suggéré que l’on coupât l’arbre au lieu d’y pratiquer un carottage. Il y a aussi quelque incertitude quant à la raison pour laquelle un carottage n’a pu être fait. Une version est qu’il a brisé son unique longue tarière d’accroissement ou n’arrivait pas à la retirer et qu’il ne pouvait pas en obtenir une autre avant la fin de la campagne sur le terrain, une autre version prétend qu’il avait cassé deux tarières, et une autre encore qu’un échantillon de base était trop difficile à obtenir par taraudage et qu’il n’aurait pas fourni autant de renseignements définitifs qu’une coupe transversale complète de l’arbre.

    Il s’y ajoute des différences d’opinion sur le caractère exceptionnel de Prométhée dans le bosquet du pic Wheeler. On a dit que Currey et/ou le personnel de service forestier qui a autorisé l’abattage croyaient que l’arbre était seulement un des arbres très grands et très vieux dans le bosquet, tandis que d’autres, parmi lesquels un au moins a été impliqué dans la prise de décision et l’abattage de l’arbre, croyaient que l’arbre était vraiment exceptionnel - manifestement plus vieux que les autres arbres du domaine. Au moins une des personnes impliquées assure que Currey savait la vérité à l’époque bien que lui-même ne l’ait jamais avoué ; d’autres au contraire ont contesté que l’arbre fût de façon évidente plus vieux que les autres.

    On ne voit pas bien non plus en quoi il était nécessaire d’abattre un arbre aussi vieux si l’on considère le sujet que Currey étudiait. Comme le petit âge glaciaire a commencé, il n’y a pas plus de 600 ans, bien des arbres sans doute auraient pu fournir les renseignements qu’il recherchait pour cette période de temps. Pourtant, dans son rapport original (Currey, 1965), Currey fait allusion au petit âge glaciaire comme embrassant une période allant de 2000 avant Jésus-Christ jusqu’à maintenant, définissant ainsi cet âge comme une période de temps beaucoup plus longue que selon le consensus habituel. Était-ce l’opinion ordinaire à ce moment-là, on ne le sait pas. Dans l’article, Currey indique qu’il avait fait abattre l’arbre autant pour savoir si les bristlecones les plus âgés ont été nécessairement confinés aux Montagnes Blanches de Californie (comme des dendrochronologistes lui en avaient fait la demande) que parce que c’était utile pour étudier le petit âge glaciaire.

    Quoi qu’il en soit, l’arbre a été abattu et sectionné en août 1964, et plusieurs morceaux ont été emportés pour être traités et analysés, d’abord par Currey, puis par d’autres dans les années suivantes. Des sections, ou des morceaux de sections ont abouti à différents endroits, dont certains sont ouverts au public, entre autres : le centre de visite du parc national de Great Basin (Baker, NV), le Convention Center d’Ely (Ely, NV), le Laboratoire de Recherche sur les anneaux des arbres de l’université d’Arizona (Tucson, AZ) et l’Institut de génétique forestière du Service forestier américain (Placerville, CA).
    Répercussions de l’abattage de l’arbre

    On a soutenu que l’abattage de l’arbre a été un facteur important pour le mouvement de protection des bristlecones en général et des bosquets du pic Wheeler en particulier. Avant que l’arbre eût été coupé il y avait déjà eu un mouvement pour protéger les zones montagneuses et contiguës à l’intérieur d’un parc national et 22 ans après l’incident la région a vraiment acquis le statut de parc national.

    L’endroit exact de l’arbre qui est maintenant le plus vieux, Mathusalem, est gardé secret par l’agence chargée de l’administration, le Service des forêts américain. À cause de l’importance de l’espèce dans les recherches de dendrochronologie, tous les pins bristlecones sont maintenant protégés, qu’ils soient debout ou tombés.

  • Who writes history? The fight to commemorate a massacre by the Texas #rangers

    In 1918, a state-sanctioned vigilante force killed 15 unarmed Mexicans in #Porvenir. When their descendants applied for a historical marker a century later, they learned that not everyone wants to remember one of Texas’ darkest days.

    The name of the town was Porvenir, or “future.” In the early morning hours of January 28, 1918, 15 unarmed Mexicans and Mexican Americans were awakened by a state-sanctioned vigilante force of Texas Rangers, U.S. Army cavalry and local ranchers. The men and boys ranged in age from 16 to 72. They were taken from their homes, led to a bluff over the Rio Grande and shot from 3 feet away by a firing squad. The remaining residents of the isolated farm and ranch community fled across the river to Mexico, where they buried the dead in a mass grave. Days later, the cavalry returned to burn the abandoned village to the ground.

    These, historians broadly agree, are the facts of what happened at Porvenir. But 100 years later, the meaning of those facts remains fiercely contested. In 2015, as the centennial of the massacre approached, a group of historians and Porvenir descendants applied for and was granted a Texas Historical Commission (THC) marker. After a three-year review process, the THC approved the final text in July. A rush order was sent to the foundry so that the marker would be ready in time for a Labor Day weekend dedication ceremony planned by descendants. Then, on August 3, Presidio County Historical Commission Chair Mona Blocker Garcia sent an email to the THC that upended everything. Though THC records show that the Presidio commission had been consulted throughout the marker approval process, Garcia claimed to be “shocked” that the text was approved. She further asserted, without basis, that “the militant Hispanics have turned this marker request into a political rally and want reparations from the federal government for a 100-year-old-plus tragic event.”

    Four days later, Presidio County Attorney Rod Ponton sent a follow-up letter. Without identifying specific errors in the marker text, he demanded that the dedication ceremony be canceled and the marker’s production halted until new language could be agreed upon. Ponton speculated, falsely, that the event was planned as a “major political rally” for Beto O’Rourke with the participation of La Raza Unida founding member José Ángel Gutiérrez, neither of whom was involved. Nonetheless, THC History Programs Director Charles Sadnick sent an email to agency staff the same day: “After getting some more context about where the marker sponsor may be coming from, we’re halting production on the marker.”

    The American Historical Association quickly condemned the THC’s decision, as did the office of state Senator José Rodríguez, a Democrat whose district includes both Presidio County and El Paso, where the ceremony was to be held. Historians across the country also spoke out against the decision. Sarah Zenaida Gould, director of the Museo del Westside in San Antonio and cofounder of Latinos in Heritage Conservation, responded in an email to the agency that encapsulates the views of many of the historians I interviewed: “Halting the marker process to address this statement as though it were a valid concern instead of a dog whistle is insulting to all people of color who have personally or through family history experienced state violence.”

    How did a last-gasp effort, characterized by factual errors and inflammatory language, manage to convince the state agency for historic preservation to reverse course on a marker three years in the making and sponsored by a young Latina historian with an Ivy League pedigree and Texas-Mexico border roots? An Observer investigation, involving dozens of interviews and hundreds of emails obtained through an open records request, reveals a county still struggling to move on from a racist and violent past, far-right amateur historians sowing disinformation and a state agency that acted against its own best judgment.

    The Porvenir massacre controversy is about more than just the fate of a single marker destined for a lonely part of West Texas. It’s about who gets to tell history, and the continuing relevance of the border’s contested, violent and racist past to events today.

    Several rooms in Benita Albarado’s home in Uvalde are almost overwhelmed by filing cabinets and stacks of clipboards, the ever-growing archive of her research into what happened at Porvenir. For most of her life, Benita, 74, knew nothing about the massacre. What she did know was that her father, Juan Flores, had terrible nightmares, and that in 1950 he checked himself in to a state mental hospital for symptoms that today would be recognized as PTSD. When she asked her mother what was wrong with him, she always received the same vague response: “You don’t understand what he’s been through.”

    In 1998, Benita and her husband, Buddy, began tracing their family trees. Benita was perplexed that she couldn’t find any documentation about her grandfather, Longino Flores. Then she came across the archival papers of Harry Warren, a schoolteacher, lawyer and son-in-law of Tiburcio Jáquez, one of the men who was murdered. Warren had made a list of the victims, and Longino’s name was among them. Warren also described how one of his students from Porvenir had come to his house the next morning to tell him what happened, and then traveled with him to the massacre site to identify the bodies, many of which were so mutilated as to be virtually unrecognizable. Benita immediately saw the possible connection. Her father, 12 at the time, matched Warren’s description of the student.

    Benita and Buddy drove from Uvalde to Odessa, where her father lived, with her photocopied papers. “Is that you?” she asked. He said yes. Then, for the first time in 80 years, he began to tell the story of how he was kidnapped with the men, but then sent home because of his age; he was told that the others were only going to be questioned. To Benita and Buddy’s amazement, he remembered the names of 12 of the men who had been murdered. They were the same as those in Harry Warren’s papers. He also remembered the names of the ranchers who had shown up at his door. Some of those, including the ancestors of prominent families still in Presidio County, had never been found in any document.

    Talking about the massacre proved healing for Flores. His nightmares stopped. In 2000, at age 96, he decided that he wanted to return to Porvenir. Buddy drove them down an old mine road in a four-wheel-drive truck. Flores pointed out where his old neighbors used to live, even though the buildings were gone. He guided Buddy to the bluff where the men were killed — a different location than the one commonly believed by local ranchers to be the massacre site. His memory proved to be uncanny: At the bluff, the family discovered a pre-1918 military bullet casing, still lying on the Chihuahuan desert ground.

    Benita and Buddy began advocating for a historical marker in 2000, soon after their trip to Porvenir. “A lot of people say that this was a lie,” Buddy told me. “But if you’ve got a historical marker, the state has to acknowledge what happened.” Their efforts were met by resistance from powerful ranching families, who held sway over the local historical commission. The Albarados had already given up when they met Monica Muñoz Martinez, a Yale graduate student from Uvalde, who interviewed them for her dissertation. In 2013, Martinez, by then an assistant professor at Brown University, co-founded Refusing to Forget, a group of historians aiming to create broader public awareness of border violence, including Porvenir and other extrajudicial killings of Mexicans by Texas Rangers during the same period. The most horrific of these was La Matanza, in which dozens of Mexicans and Mexican Americans were murdered in the Rio Grande Valley in 1915.

    In 2006, the THC created the Undertold Markers program, which seemed tailor-made for Porvenir. According to its website, the program is designed to “address historical gaps, promote diversity of topics, and proactively document significant underrepresented subjects or untold stories.” Unlike the agency’s other marker programs, anyone can apply for an undertold marker, not just county historical commissions. Martinez’s application for a Porvenir massacre marker was accepted in 2015.

    Though the approval process for the Porvenir marker took longer than usual, by the summer of 2018 everything appeared to be falling into place. On June 1, Presidio County Historical Commission chair Garcia approved the final text. (Garcia told me that she thought she was approving a different text. Her confusion is difficult to understand, since the text was attached to the digital form she submitted approving it.) Martinez began coordinating with the THC and Arlinda Valencia, a descendant of one of the victims, to organize a dedication ceremony in El Paso.
    “They weren’t just simple farmers. I seriously doubt that they were just killed for no reason.”

    In mid-June, Valencia invited other descendants to the event and posted it on Facebook. She began planning a program to include a priest’s benediction, a mariachi performance and brief remarks by Martinez, Senator Rodríguez and a representative from the THC. The event’s climax would be the unveiling of the plaque with the names of the 15 victims.

    Then the backlash began.

    “Why do you call it a massacre?” is the first thing Jim White III said over the phone when I told him I was researching the Porvenir massacre. White is the trustee of the Brite Ranch, the site of a cross-border raid by Mexicans on Christmas Day 1917, about a month before the Porvenir massacre. When I explained that the state-sanctioned extrajudicial execution of 15 men and boys met all the criteria I could think of for a massacre, he shot back, “It sounds like you already have your opinion.”

    For generations, ranching families like the Brites have dominated the social, economic and political life of Presidio County. In a visit to the Marfa & Presidio County Museum, I was told that there were almost no Hispanic surnames in any of the exhibits, though 84 percent of the county is Hispanic. The Brite family name, however, was everywhere.

    White and others in Presidio County subscribe to an alternative history of the Porvenir massacre, centering on the notion that the Porvenir residents were involved in the bloody Christmas Day raid.

    “They weren’t just simple farmers,” White told me, referring to the victims. “I seriously doubt that they were just killed for no reason.” Once he’d heard about the historical marker, he said, he’d talked to everyone he knew about it, including former Texas Land Commissioner Jerry Patterson and Mona Blocker Garcia.

    I visited Garcia at her Marfa home, an 1886 adobe that’s the same age as the venerable Marfa County Courthouse down the street. Garcia, 82, is Anglo, and married to a former oil executive whose ancestry, she explained, is Spanish and French Basque. A Houston native, she retired in the 1990s to Marfa, where she befriended the Brite family and became involved in local history. She told me that she had shared a draft text of the marker with the Brites, and they had agreed that it was factually inaccurate.

    Garcia cited a story a Brite descendant had told her about a young goat herder from Porvenir who purportedly witnessed the Christmas Day raid, told authorities about the perpetrators from his community and then disappeared without a trace into a witness protection program in Oklahoma. When I asked if there was any evidence that the boy actually existed, she acknowledged the story was “folklore.” Still, she said, “the story has lasted 100 years. Why would anybody make something like that up?”

    The actual history is quite clear. In the days after the massacre, the Texas Rangers commander, Captain J.M. Fox, initially reported that Porvenir residents had fired on the Rangers. Later, he claimed that residents had participated in the Christmas Day raid. Subsequent investigations by the Mexican consulate, the U.S. Army and state Representative J.T. Canales concluded that the murdered men were unarmed and innocent, targeted solely because of their ethnicity by a vigilante force organized at the Brite Ranch. As a result, in June 1918, five Rangers were dismissed, Fox was forced to resign and Company B of the Texas Rangers was disbanded.

    But justice remained elusive. In the coming years, Fox re-enlisted as captain of Company A, while three of the dismissed lawmen found new employment. One re-enlisted as a Ranger, a second became a U.S. customs inspector and the third was hired by the Brite Ranch. No one was ever prosecuted. As time passed, the historical records of the massacre, including Harry Warren’s papers, affidavits from widows and other relatives and witness testimony from the various investigations, were largely forgotten. In their place came texts like Walter Prescott Webb’s The Texas Rangers: A Century of Frontier Defense, which played an outsize role in the creation of the heroic myth of the Texas Rangers. Relying entirely on interviews with the murderers themselves, Webb accepted at face value Fox’s discredited version of events. For more than 50 years, Webb’s account was considered the definitive one of the massacre — though, unsurprisingly, he didn’t use that word.

    An Observer review of hundreds of emails shows that the state commission was aware of potential controversy over the marker from the very beginning. In an email from 2015, Executive Director Mark Wolfe gave John Nau, the chair of the THC’s executive committee, a heads-up that while the marker was supported by historical scholarship, “the [Presidio County Historical Commission] opposes the marker.” The emails also demonstrate that the agency viewed the claims of historical inaccuracies in the marker text made by Mona Blocker Garcia and the county commission as minor issues of wording.

    On August 6, the day before the decision to halt the marker, Charles Sadnick, the history programs director, wrote Wolfe to say that the “bigger problem” was the ceremony, where he worried there might be disagreements among Presidio County residents, and which he described as “involving some politics which we don’t want a part of.”

    What were the politics that the commission was worried about, and where were these concerns coming from? Garcia’s last-minute letter may have been a factor, but it wasn’t the only one. For the entire summer, Glenn Justice, a right-wing amateur historian who lives in a rural gated community an hour outside San Angelo, had been the driving force behind a whisper campaign to discredit Martinez and scuttle the dedication ceremony.

    “There are radicals in the ‘brown power’ movement that only want the story told of Rangers and [the] Army and gringos killing innocent Mexicans,” Justice told me when we met in his garage, which doubles as the office for Rimrock Press, a publishing company whose catalog consists entirely of Justice’s own work. He was referring to Refusing to Forget and in particular Martinez, the marker’s sponsor.

    Justice has been researching the Porvenir massacre for more than 30 years, starting when he first visited the Big Bend as a graduate student. He claims to be, and probably is, the first person since schoolteacher Harry Warren to call Porvenir a “massacre” in print, in a master’s thesis published by the University of Texas at El Paso in 1991. Unlike White and Garcia, Justice doesn’t question the innocence of the Porvenir victims. But he believes that additional “context” is necessary to understand the reasons for the massacre, which he views as an aberration, rather than a representatively violent part of a long history of racism. “There have never been any problems between the races to speak of [in Presidio County],” he told me.

    In 2015, Justice teamed up with former Land Commissioner Jerry Patterson and Sul Ross State University archaeologist David Keller on a privately funded excavation at the massacre site. He is working on a new book about the bullets and bullet casings they found — which he believes implicate the U.S. Army cavalry in the shooting — and also partnered with Patterson to produce a documentary. But they’d run out of money, and the film was taken over by noted Austin filmmaker Andrew Shapter, who pitched the project to PBS and Netflix. In the transition, Justice was demoted to the role of one of 12 consulting historians. Meanwhile, Martinez was given a prominent role on camera.

    Justice was disgruntled when he learned that the dedication ceremony would take place in El Paso. He complained to organizer Arlinda Valencia and local historical commission members before contacting Ponton, the county attorney, and Amanda Shields, a descendant of massacre victim Manuel Moralez.

    “I didn’t want to take my father to a mob scene,” Shields told me over the phone, by way of explaining her opposition to the dedication ceremony. She believed the rumor that O’Rourke and Gutiérrez would be involved.

    In August, Shields called Valencia to demand details about the program for the ceremony. At the time, she expressed particular concern about a potential Q&A event with Martinez that would focus on parallels between border politics and violence in 1918 and today.

    “This is not a political issue,” Shields told me. “It’s a historical issue. With everything that was going on, we didn’t want the ugliness of politics involved in it.” By “everything,” she explained, she was referring primarily to the issue of family separation. Benita and Buddy Albarado told me that Shields’ views represent a small minority of descendants.

    Martinez said that the idea of ignoring the connections between past and present went against her reasons for fighting to get a marker in the first place. “I’m a historian,” she said. “It’s hard to commemorate such a period of violence, in the midst of another ongoing humanitarian crisis, when this period of violence shaped the institutions of policing that we have today. And that cannot be relegated to the past.”

    After communicating with Justice and Shields, Ponton phoned THC Commissioner Gilbert “Pete” Peterson, who is a bank investment officer in Alpine. That call set in motion the sequence of events that would ultimately derail the marker. Peterson immediately emailed Wolfe, the state commission’s executive director, to say that the marker was becoming “a major political issue.” Initially, though, Wolfe defended the agency’s handling of the marker. “Frankly,” Wolfe wrote in his reply, “this might just be one where the [Presidio County Historical Commission] isn’t going to be happy, and that’s why these stories have been untold for so long.” Peterson wrote back to say that he had been in touch with members of the THC executive committee, which consists of 15 members appointed by either former Governor Rick Perry or Governor Greg Abbott, and that an email about the controversy had been forwarded to THC chair John Nau. Two days later, Peterson added, “This whole thing is a burning football that will be thrown to the media.”

    At a meeting of the Presidio County Historical Commission on August 17, Peterson suggested that the executive board played a major role in the decision to pause production of the marker. “I stopped the marker after talking to Rod [Ponton],” Peterson said. “I’ve spent quite a bit of time talking with the chairman and vice-chairman [of the THC]. What we have said, fairly emphatically, is that there will not be a dedication in El Paso.” Through a spokesperson, Wolfe said that the executive committee is routinely consulted and the decision was ultimately his.

    The spokesperson said, “The big reason that the marker was delayed was to be certain about its accuracy. We want these markers to stand for generations and to be as accurate as possible.”

    With no marker to unveil, Valencia still organized a small commemoration. Many descendants, including Benita and Buddy Albarado, chose not to attend. Still, the event was described by Jeff Davis, a THC representative in attendance, as “a near perfect event” whose tone was “somber and respectful but hopeful.”

    Most of THC’s executive committee members are not historians. The chair, John Nau, is CEO of the nation’s largest Anheuser-Busch distributor and a major Republican party donor. His involvement in the Porvenir controversy was not limited to temporarily halting the marker. In August, he also instructed THC staff to ask the Presidio historical commission to submit applications for markers commemorating raids by Mexicans on white ranches during the Mexican Revolution, which Nau described as “a significant but largely forgotten incident in the state’s history.”

    Garcia confirmed that she had been approached by THC staff. She added that the THC had suggested two specific topics: the Christmas Day raid and a subsequent raid at the Neville Ranch.

    The idea of additional plaques to provide so-called context that could be interpreted as justifying the massacre — or at the very least setting up a false moral equivalence — appears to have mollified critics like White, Garcia and Justice. The work on a revised Porvenir massacre text proceeded quickly, with few points of contention, once it began in mid-September. The marker was sent to the foundry on September 18.
    “It’s hard to commemorate such a period of violence, in the midst of another ongoing humanitarian crisis, when this period of violence shaped the institutions of policing that we have today.”

    In the end, the Porvenir descendants will get their marker — but it may come at a cost. Martinez called the idea of multiple markers “deeply unsettling” and not appropriate for the Undertold Marker program. “Events like the Brite Ranch raid and the Neville raid have been documented by historians for over a century,” she said. “These are not undertold histories. My concern with having a series of markers is that, again, it casts suspicion on the victims of these historical events. It creates the logic that these raids caused this massacre, that it was retribution for these men and boys participating.”

    In early November, the THC unexpectedly announced a dedication ceremony for Friday, November 30. The date was one of just a few on which Martinez, who was still planning on organizing several public history events in conjunction with the unveiling, had told the agency months prior that she had a schedule conflict. In an email to Martinez, Sadnick said that it was the only date Nau could attend this year, and that it was impossible for agency officials to make “secure travel plans” once the legislative session began in January.

    A handful of descendants, including Shields and the Albarados, still plan to attend. “This is about families having closure,” Shields told me. “Now, this can finally be put to rest.”

    The Albarados are livid that the THC chose a date that, in their view, prioritized the convenience of state and county officials over the attendance of descendants — including their own daughters, who feared they wouldn’t be able to get off work. They also hope to organize a second, unofficial gathering at the marker site next year, with the participation of more descendants and the Refusing to Forget historians. “We want people to know the truth of what really happened [at Porvenir],” Buddy told me, “and to know who it was that got this historical marker put there.”

    Others, like Arlinda Valencia, planned to stay home. “Over 100 years ago, our ancestors were massacred, and the reason they were massacred was because of lies that people were stating as facts,” she told me in El Paso. “They called them ‘bandits,’ when all they were doing was working and trying to make a living. And now, it’s happening again.”

    Trop fun : quand le Parti Républicain essaie de décrédibiliser un candidat démocrate du Texas en expliquant qu’il était membre d’un groupe de punk... voilà que cela se retourne contre lui. ne série d’exemple de Tweets trop drôles.

    The Texas Republican Party tried to shame Democratic candidate Beto O’Rourke on Twitter for his unconventional past — but it hilariously backfired.

    The 45-year-old O’Rourke played bass in the alternative band Foss, which released a pair of albums on Western Breed Records and toured the U.S. and Canada in the mid-1990s, and he has openly discussed his arrests on misdemeanor charges during that same period.

    O’Rourke was charged in 1995 with burglary for jumping a fence at the University of Texas at El Paso and in 1998 with driving under the influence, but he was not convicted of either charge and has publicly addressed his arrests when asked.

  • 50 years of U.S. mass shootings: The victims, sites, killers and weapons - Washington Post
    https://www.washingtonpost.com/graphics/national/mass-shootings-in-america

    he death tolls change, the places change: 26 at a church, 26 in an elementary school, 49 in a nightclub, 58 at a country music festival. The faces in the memorial photos change every time.

    But the weapons are the common denominator.

    Mass killings in the United States are most often carried out with guns, usually handguns, most of them obtained legally.

    There is no universally accepted definition of a mass shooting, and different organizations use different criteria. In this piece we use a narrow definition and look only at the deadliest mass shootings, beginning Aug. 1, 1966, when ex-Marine sniper Charles Whitman killed his wife and mother, then climbed a 27-story tower at the University of Texas and killed 14 more people before police shot him to death. The numbers here refer to 132 events in which four or more people were killed by a lone shooter (or two shooters in three cases). An average of eight people died during each event, often including the shooters.

  • Socialism is surging on college campuses this fall – VICE News
    https://news.vice.com/story/socialism-is-surging-on-college-campuses-this-fall

    “This is only a good thing for the Democratic Party,” said Sabrina Singh, the deputy communications director at the Democratic National Committee, said of the rise of YDSA [Young Democratic Socialists of America]. “There is incredible enthusiasm on college campuses across the country, and we’ve seen a number of groups rise to bring about progressive change and get involved in Democratic politics.”

    But eight YDSA organizers at colleges across the country said that helping the Democrats is not their goal. Instead, they want to remain distinct and offer a more progressive alternative to the Democratic Party. “Democrats have more moderation, but it’s the same policy of class war as the Republicans,” Chance Walker, the co-chair of the new YDSA chapter at University of Texas San Antonio, told VICE News.

    At UT San Antonio — where half of the student body is Hispanic, a key constituency for Democrats — there is now only a socialists club and not a Democratic one. The College Dems club at UT San Antonio went kaput in 2016, according to the university, and Walker helped start a YDSA chapter this past fall.

  • #Caspian_Sea evaporating as temperatures rise, study finds
    http://news.agu.org/press-release/caspian-sea-evaporating-as-temperatures-rise-study-finds
    http://sites.agu.org/files/2017/08/The-Caspian-Sea-from-Space.jpg

    Earth’s largest inland body of water has been slowly evaporating for the past two decades due to rising temperatures associated with climate change, a new study finds.

    Water levels in the Caspian Sea dropped nearly 7 centimeters (3 inches) per year from 1996 to 2015, or nearly 1.5 meters (5 feet) total, according to the new study. The current Caspian Sea level is only about 1 meter (3 feet) above the historic low level it reached in the late 1970s.

    Increased evaporation over the Caspian Sea has been linked to increased surface air temperatures. According to the data from the study, the average yearly surface temperature over the Caspian Sea rose by about 1 degree Celsius (1.8 degrees Fahrenheit) between the two time frames studied, 1979-1995 and 1996-2015. These rising temperatures are likely a result of climate change, according to the study’s authors.

    Evaporation brought about by warming temperatures appears to be the primary cause of the current drop in sea level and the decline will likely continue as the planet warms, according to the study’s authors.

    From our point of view as geoscientists, it’s an interesting place because it’s possible to construct a sort of budget for the total amount of water that’s there,” said Clark Wilson, a geophysicist with the Jackson School of Geosciences at the University of Texas at Austin, and co-author of the new study published in Geophysical Research Letters, a journal of the American Geophysical Union. “The real control that causes it to go up and down over long periods of time is really most likely the evaporation, which is almost completely dominated by temperature.

    http://nautil.us/blog/how-should-society-judge-a-defendant-with-a-brain-tumor

    After a visit from one of his patients in March, 1966, the psychiatrist Maurice Heatly noted, “This massive, muscular youth seemed to be oozing with hostility as he initiated the hour with the statement that something was happening to him and he didn’t seem to be himself.” That patient was Charles Whitman, a 25-year-old former Marine who had recently been honorably discharged. He told Heatly, who was on staff at the University of Texas Health Center, in Austin, that he’d been “thinking about going up on the tower [on campus] with a deer rifle and start shooting people.” Several months later, he did just that, killing 14 people, and wounding 31, before being shot dead by the police.

  • AI can recognise your face even if you’re pixelated

    “Researchers at the University of Texas at Austin and Cornell Tech say that they’ve trained a piece of software that can undermine the privacy benefits of standard content-masking techniques like blurring and pixelation by learning to read or see what’s meant to be hidden in images—anything from a blurred house number to a pixelated human face in the background of a photo.”

    https://www.wired.com/2016/09/machine-learning-can-identify-pixelated-faces-researchers-show/?mbid=social_fb

    The researchers were able to defeat three privacy protection technologies, starting with YouTube’s proprietary blur tool. YouTube allows uploaders to select objects or figures that they want to blur, but the team used their attack to identify obfuscated faces in videos. In another example of their method, the researchers attacked pixelation (also called mosaicing). To generate different levels of pixelation, they used their own implementation of a standard mosaicing technique that the researchers say is found in Photoshop and other commons programs. And finally, they attacked a tool called Privacy Preserving Photo Sharing (P3), which encrypts identifying data in JPEG photos so humans can’t see the overall image, while leaving other data components in the clear so computers can still do things with the files like compress them.

    • Border Security Fencing and Wildlife: The End of the Transboundary Paradigm in Eurasia?

      The ongoing refugee crisis in Europe has seen many countries rush to construct border security fencing to divert or control the flow of people. This follows a trend of border fence construction across Eurasia during the post-9/11 era. This development has gone largely unnoticed by conservation biologists during an era in which, ironically, transboundary cooperation has emerged as a conservation paradigm. These fences represent a major threat to wildlife because they can cause mortality, obstruct access to seasonally important resources, and reduce effective population size. We summarise the extent of the issue and propose concrete mitigation measures.

    • Rewriting biological history: Trump border wall puts wildlife at risk

      Mexican conservationists are alarmed over Trump’s wall, with the loss of connectivity threatening already stressed bison, pronghorn, bighorn sheep, bears and other animals.
      About one-third of the border, roughly 700 miles, already has fencing; President Trump has been pushing a controversial plan to fence the remainder.
      A wall running the entire nearly 2,000-mile frontier from the Pacific Ocean to the Gulf of Mexico, conservationists warn, would be catastrophic for borderland ecosystems and many wildlife species, undoing years of environmental cooperation between the two countries to protect animals that must move freely or die.
      The wall is currently a key bargaining chip, and a sticking point, in ongoing immigration legislation negotiations taking place this week in Congress. Also expected this week: a federal court ruling on whether the administration can legally waive environmental laws to expedite border wall construction.

      The national debate about border security doesn’t often dwell on the natural environment, but hundreds of miles of public lands, including six national parks, sit along the U.S.-Mexico border. What will happen to these lands — and the wildlife and plants they protect — if a wall or additional fences and barriers are built along the frontier?

    • Activists Vow Fight as Congress Funds Portions of Border Wall

      Last week Congress voted to appropriate some monies to build new fortifications along the United States–Mexico border, but border activists in the Rio Grande Valley say the fight against President Donald Trump’s border wall is far from over.

      The nearly $1.6 billion in border wall funding included in the omnibus spending bill that Trump signed Friday provides for the construction of some 33 miles of new walls, all in Texas’s ecologically important Rio Grande Valley. Those walls will tear through communities, farms and ranchland, historic sites, and thousands of acres of protected wildlife habitat, while creating flooding risks on both sides of the border. But far from admitting defeat, border activists have already begun mapping out next steps to pressure Congress to slow down or even halt the wall’s construction.

    • State attorney general, environmental group to appeal decision on Trump’s border wall

      A ruling by a San Diego federal judge allowing construction of President Donald Trump’s border wall to go ahead will be appealed by two entities that opposed it, including the state Attorney General.

      Both the Center for Biological Diversity and Attorney General Xavier Becerra filed formal notices of appeal on Monday seeking to reverse a decision in February from U.S District Court Judge Gonzalo Curiel. The judge ruled that the Trump administration did not abuse its discretion in waiving environmental laws in its rush to begin border wall projects along the southwest border.

      The center had said after the ruling it would appeal, and Becerra also hinted the state would seek appellate court review at the Ninth U.S. Circuit Court of Appeals.

      The notices declare an intent to appeal. They do not outline arguments to be made on appeal or why each group believe that Curiel got it wrong.

      In a prepared statement Becerra said, “When we said that a medieval wall along the U.S.-Mexico border does not belong in the 21st century, we meant it. There are environmental and public health laws in place, and we continue to believe that the Trump Administration is violating those laws. We will not stand idly by. We are committed to protecting our people, our values and our economy from federal overreach.”

      The lawsuits challenged a law that allowed the federal government not to comply with environmental and other laws and regulations when building border security projects. They argued the law was outdated and Congress never intended for it to be an open-ended waiver for all border projects, and contended it violated constitutional provisions of separation of powers and states’ rights.

      In his decision Curiel said both that the law was constitutional and it gave the Department of Homeland Security wide latitude over border security.

      Justice Department spokesman Devin O’Malley said in response to the Curiel ruling that the administration was pleased DHS “can continue this important work vital to our nation’s interest.”

      “Border security is paramount to stemming the flow of illegal immigration that contributes to rising violent crime and to the drug crisis, and undermines national security,” O’Malley said.

    • Les murs n’arrêtent pas que les humains

      Des États-Unis à la Malaisie, en passant par Israël ou la Hongrie, les hommes construisent de multiples murs pour contraindre les déplacements de nos semblables. N’oublions pas, explique l’auteur de cette tribune, que nous ne sommes pas les seuls à habiter la Terre et donc à pâtir de ces barrières.

      La #forêt_de_Bialowieza a quelque chose de mythique et de sacré. Âgée de plus de 8.000 ans, elle est la dernière forêt primaire d’Europe. S’étalant sur 150.000 hectares entre la Pologne et la Biélorussie, inaccessible aux visiteurs sans guide assermenté, elle constitue un sanctuaire d’espèces témoignant de la richesse des mondes anciens. Le bison d’Europe y vit encore de manière naturelle, côtoyant élans, cerfs, loups, lynx, etc.

      En 1981, à l’époque du rideau de fer, l’URSS a décidé de clôturer la frontière entre la Pologne et la Biélorussie, coupant à travers cette forêt et séparant en deux la dernière population de bisons d’Europe (environ 500 individus de part et d’autre). Cette clôture est symboliquement forte, car elle témoigne de la coupure existentielle (« ontologique », diraient les philosophes) que les humains se sont imposée vis-à-vis des autres êtres vivants. Ces derniers semblent ne pas exister à nos yeux.

      Mais cette séparation est plus que symbolique, elle est concrète. Les murs dressés par l’espèce humaine représentent une menace importante et sous-estimée pour de nombreux êtres vivants non humains.
      Murs de béton, de pierre, de boue, de sable ou de brique, de barbelés, de grilles en acier ou de clôtures électrifiées

      On en trouve surtout aux frontières : entre les États-Unis et le Mexique, la Corée du Nord et du Sud, Israël et la Cisjordanie, la Malaisie et la Thaïlande, l’Inde et le Pakistan, l’Iran et l’Irak, la Chine et la Mongolie, le Botswana et le Zimbabwe, etc. Ils prennent la forme de murs de béton, de pierre, de boue, de sable ou de brique, de barbelés, de grilles en acier ou de clôtures électrifiées, et viennent accompagnés de routes, de casernes, de lumières et de bruits. Leur nombre a considérablement augmenté depuis les attentats du 11 septembre 2001. Par exemple en Eurasie (sans le Moyen-Orient), il existe aujourd’hui plus de 30.000 km de murs, grillages et barbelés aux frontières.

      Ces murs affectent évidemment les populations humaines en brisant les trajectoires personnelles de millions de personnes. Ils affectent aussi les autres espèces [1]. À Białowieża, par exemple, la séparation a empêché les flux génétiques (et a donc fragilisé) des populations de bisons, d’ours, de loups et de lynx. Pire, 25 ans après la destruction du rideau de fer entre l’Allemagne et la République tchèque, les jeunes cerfs (qui n’avaient jamais vu de clôtures) ne traversaient toujours pas la frontière [2].

      En mai 2018 paraissait dans la revue Bioscience un article cosigné par dix-huit grands noms de l’étude et de la protection de la biodiversité (dont Edward O. Wilson) et signé par 2.500 scientifiques, qui alertait sur les « conséquences inattendues mais importantes » de ces murs frontaliers sur la biodiversité [3]. Ce cri d’alarme n’est pas le premier [4], mais il résume bien l’état des lieux de la recherche, et aussi l’état de préoccupation des chercheurs.
      Lorsque les habitats se fragmentent, les territoires des populations se réduisent

      Les murs nuisent à la biodiversité de plusieurs façons. Premièrement, ils peuvent blesser ou tuer des animaux directement, quand ils s’emmêlent dans les fils barbelés, sont électrocutés ou marchent sur des mines antipersonnelles.

      Deuxièmement, ils fragmentent et dégradent les habitats. Par exemple la frontière de 3.200 km entre le Mexique et les États-Unis traverse les aires de répartition géographique de 1.506 espèces natives (parmi lesquelles 1.077 espèces animales) dont 62 sont sur la liste des espèces en danger. Le mur menace cinq régions particulièrement riches en biodiversité (on les nomme « hotspots ») qui retiennent presque tous les efforts de conservation et de « réensauvagement » (rewilding). Lorsque les habitats se fragmentent, les territoires des populations se réduisent, et le nombre d’espèces présentes sur ces petites surfaces se réduit plus que proportionnellement, rendant ainsi les populations plus vulnérables, par exemple aux variations climatiques. Les clôtures frontalières contribuent aussi à accroître la mortalité de la faune sauvage en facilitant la tâche des braconniers, en perturbant les migrations et la reproduction, et en empêchant l’accès à la nourriture et à l’eau. Par exemple, le mouton bighorn (une espèce en danger) migrait naturellement entre la Californie et le Mexique mais ne peut aujourd’hui plus accéder aux points d’eau et aux sites de naissance qu’il avait l’habitude de fréquenter.

      Troisièmement, ces murs annulent les effets bénéfiques des millions de dollars investis dans la recherche et les mesures de conservation de la biodiversité. Les scientifiques témoignent aussi du fait qu’ils sont souvent l’objet d’intimidations, de harcèlements ou de ralentissements volontaires de la part des officiers responsables de la sécurité des frontières.

      Enfin, quatrièmement, les politiques de sécurité mises en place récemment font passer les lois environnementales au deuxième plan, quand elles ne sont pas simplement bafouées ou oubliées.
      Des centaines de kilomètres de clôtures de sécurité aux frontières extérieures et intérieures de l’UE

      Le double phénomène migrations/clôtures n’est pas prêt de s’arrêter. En 2015, un afflux exceptionnel d’êtres humains fuyant leurs pays en direction de l’Europe a conduit plusieurs États membres à réintroduire ou renforcer les contrôles aux frontières, notamment par la construction rapide de centaines de kilomètres de clôtures de sécurité aux frontières extérieures et intérieures de l’UE. Le réchauffement climatique et l’épuisement des ressources seront dans les années à venir des causes majeures de guerres, d’épidémies et de famines, forçant toujours plus d’humains à migrer. Les animaux seront aussi de la partie, comme en témoigne la progression vers le nord des moustiques tigres, qui charrient avec eux des maladies qui n’existaient plus dans nos régions, ou encore l’observation du loup en Belgique en mars 2018 pour la troisième fois depuis des siècles…

      Les accords entre pays membres de l’Union européenne au sujet des migrations humaines seront-ils mis en place à temps ? Résisteront-ils aux changements et aux catastrophes à venir ? Quel poids aura la « #Convention_des_espèces_migrantes » (censée réguler le flux des animaux) face aux migrations humaines ?

      En septembre 2017, un bison d’Europe a été aperçu en Allemagne. C’était la première fois depuis 250 ans qu’un représentant sauvage de cette espèce traversait spontanément la frontière allemande. Il a été abattu par la police.

    • Les murs de séparation nuisent aussi à la #faune et la #flore

      3419 migrants sont décédés en Méditerranée en tentant de rejoindre Malte ou l’Italie. C’est ce que révèle un rapport du Haut commissariat des Nations unies pour les réfugiés publié le 10 décembre. Il y a les barrières naturelles, et les murs artificiels. Pendant deux mois, le web-documentaire Connected Walls s’attaque aux murs de séparation entre quatre continents : le mur entre l’Amérique du Nord et l’Amérique latine incarné par les grillages entre les Etats-Unis et le Mexique, celui entre l’Europe et l’Afrique incarné par les barbelés qui séparent les enclaves espagnoles du Maroc. Tous les 10 jours, Connected Walls publie un nouveau documentaire de cinq minutes sur une thématique choisie par les internautes. Cette semaine, ils ont sélectionné la thématique « animal ».

      Cette semaine, sur Connected-Walls,Valeria Fernandez (USA) et Fidel Enriquez (Mexico) ont suivi John Ladd dont la famille possède un ranch dans l’Arizona, à la frontière mexicaine, depuis cinq générations. Depuis la construction du mur frontalier en 2007, les choses ont changé pour lui et pour les animaux.

      De leur côté, Irene Gutierrez (Espagne) et Youssef Drissi (Maroc) ont rencontré Adam Camara, un jeune de Guinée Équatoriale qui a tenté de traverser plusieurs fois le détroit entre le Maroc et l’Espagne. Lors de sa dernière tentative, il a reçu l’aide d’un mystérieux ami.
      Pour chaque thématique, un partenaire associatif a carte blanche pour rédiger une tribune. Celle-ci a été rédigée par Dan Millis, de l’organisation écologiste Sierra Club :

      « Les animaux se moquent bien des frontières politiques. Le jaguar de Sonora n’a pas de passeport, et le canard morillon cancane avec le même accent, qu’il soit à Ceuta ou dans la forêt de Jbel Moussa. Les murs et les barrières ont cependant un impact considérable sur la faune et la flore. Par exemple, les rennes de l’ancienne Tchécoslovaquie ne franchissent jamais la ligne de l’ancien Rideau de Fer, alors même que cette barrière a disparu depuis 25 ans et qu’aucun des rennes vivant aujourd’hui ne l’a jamais connue. Les quelques 1000 kilomètres de barrières et de murs séparant les États-Unis et le Mexique détruisent et fragmentent l’habitat sauvage, en bloquant les couloirs de migration essentiels à la survie de nombreuses espèces. Une étude réalisée grâce à des caméras installées au niveau des refuges et des zones de vie naturellement fréquentés par la faune en Arizona a montré que des animaux comme le puma et le coati sont bloqués par les murs des frontières, alors que les humains ne le sont pas. »

    • Border Fences and their Impacts on Large Carnivores, Large Herbivores and Biodiversity: An International Wildlife Law Perspective

      Fences, walls and other barriers are proliferating along international borders on a global scale. These border fences not only affect people, but can also have unintended but important consequences for wildlife, inter alia by curtailing migrations and other movements, by fragmenting populations and by causing direct mortality, for instance through entanglement. Large carnivores and large herbivores are especially vulnerable to these impacts. This article analyses the various impacts of border fences on wildlife around the world from a law and policy perspective, focusing on international wildlife law in particular. Relevant provisions from a range of global and regional legal instruments are identified and analysed, with special attention for the Bonn Convention on Migratory Species and the European Union Habitats Directive.

    • Butterfly Preserve On The Border Threatened By Trump’s Wall

      The National Butterfly Center, a 100-acre wildlife center and botanical garden in South Texas, provides a habitat for more than 100 species of butterflies.

      It also sits directly in the path of the Trump administration’s proposed border wall.

      The federal spending bill approved in September includes $1.6 billion in 2019 for construction of the wall. In October, the Department of Homeland Security issued a waiver to 28 laws protecting public lands, wildlife and the environment to clear the way for construction to proceed.

    • Wildlife advocates, local indigenous tribes protest preparations for new border wall construction

      The federal government this week began moving bulldozers and construction vehicles to the Texas border with Mexico to begin building a new six-mile section of border wall — the first new wall under President Donald Trump, administration officials confirmed Tuesday.

      The move immediately triggered angry protests by a local butterfly sanctuary — The National Butterfly Center — and local indigenous tribes who oppose the wall and say construction will damage natural habitats. U.S. Customs and Border Protection said the wall will run through land owned by federal government. The dispute came amid an administration claim that a caravan of 2,000 migrants had arrived in northern Mexico along the Texas border.

      “We’re a recognized tribe and no one’s going to tell us who we are especially some idiots in Washington,” said Juan Mancias of the indigenous peoples’ tribe Carrizo-Comecrudo, who led protests on Monday. “We’re the original people of this land. We haven’t forgot our ancestors.”

      So far, the Trump administration has upgraded only existing fencing along the border. The president has called for some $5 billion for new wall construction, and Democrats have refused, resulting in a budget dispute that shut down the government for five weeks.

      This latest Texas project relies on previously appropriated money and won’t require further congressional approval. Construction plans for the Rio Grande Valley, just south of McAllen, Texas, call for six to 14 miles of new concrete wall topped with 18-foot vertical steel bars.

      Last year, Homeland Security Secretary Kristen Nielsen waived a variety environmental restrictions, including parts of the Endangered Species and Clean Water Acts, to prepare for construction in the area. Construction on the Rio Grande Valley project is expected to start in the coming weeks.

      Marianna Wright, executive director of the National Butterfly Center, remains a staunch advocate against the border wall. She met this week with authorities who she said wants to buy the center’s land for wall construction.

      She traveled to Washington last month to explain the environmental damage that would be caused by the construction in testimony on Capitol Hill.

      “The bulldozers will roll into the lower Rio Grande Valley wildlife conservation corridor, eliminating thousands of trees during spring nesting season for hundreds of species of migratory raptors and songbirds,” Wright told the House Natural Resources Committee.

      When asked by ABC News what message she has for people who aren’t there to see the impact of the new border wall, Wright paused, searching for words to express her frustration.

      “I would drive my truck over them, over their property, through their fence,” she said.

      DHS continues to cite national security concerns as the reason for building the border wall, with Homeland Secretary Kirstjen Nielsen saying in a statement Tuesday that migrants in the new caravan that had arrived at the Texas border would try to cross over illegally.

      “Such caravans are the result of Congress’s inexcusable failure to fully fund a needed physical barrier and unwillingness to fix outdated laws that act as an enormous magnet for illegal aliens,” Nielsen said in a statement.

      The last so-called caravan that caused alarm for the administration resulted in thousands of migrants taking shelter in the Mexican city of Tijuana. Just across the border from San Diego, many waited several weeks for the chance to enter the U.S.

    • As Work Begins on Trump’s Border Wall, a Key Wildlife Refuge Is at Risk

      Construction is underway on a stretch of President Trump’s border wall cutting through the Lower Rio Grande Valley National Wildlife Refuge in Texas. Biologists warn the steel wall will disrupt carefully preserved habitat critical for the survival of ocelot, jaguarundi, and other threatened species.

      As Tiffany Kersten descends from a levee into a verdant forest that stretches to the Rio Grande more than a mile away, she spots a bird skimming the treetops: a red-tailed hawk. Later, other birds — great blue herons, egrets — take flight from the edge of an oxbow lake. This subtropical woodland is one of the last remnants of tamaulipan brushland — a dense tangle of Texas ebony, mesquite, retama, and prickly pear whose U.S. range is now confined to scattered fragments in the Lower Rio Grande Valley in south Texas. The ecosystem harbors an astonishing array of indigenous wildlife: ocelot, jaguarundi, Texas tortoise, and bobcat, as well as tropical and subtropical birds in a rainbow of colors, the blue bunting and green jay among them.

      But the stretch of tamaulipan scrub Kersten is exploring, in the Lower Rio Grande Valley National Wildlife Refuge, won’t be around much longer. About 15 feet from the forest edge, Kersten — a board member of a local conservation group — spots red ribbons tied to tree branches on both sides of the trail. Soon, an excavator will uproot those trees to make way for a 140-foot-wide access road and an 18-foot-high wall atop the levee, all part of the Trump administration’s plan to barricade as much of the Texas/Mexico border as possible. On Valentine’s Day, two days before I visited the border, crews began clearing a path for the road, and soon the U.S. Department of Homeland Security (DHS) will plant a cement foundation in the levee and top it with a steel bollard barrier.

      This construction is the first project under a plan to build 33 miles of new wall along the levee in South Texas, with $641 million in funding that Trump requested and Congress authorized last year. That 33-mile stretch, cutting through some of the most unique and endangered habitat in the United States, will be joined by an additional 55 miles of wall under a funding bill Trump signed February 15 that allocates another $1.375 billion for wall construction. The same day, Trump also issued a national emergency declaration authorizing another $6 billion for border walls. That declaration could give the administration the power to override a no-wall zone Congress created in three protected areas around the Lower Rio Grande Valley National Wildlife Refuge.

      Since the mid-20th century, ranches, oil fields, and housing tracts have consumed 97 percent of the tamaulipan brushland.

      Since the mid-20th century, ranches, farms, oil fields, subdivisions, and shopping centers have consumed 97 percent of the tamaulipan brushland habitat at ground zero of this new spate of border wall construction. That loss led Congress to create the Lower Rio Grande Valley National Wildlife Refuge in the 1970s and spurred a 30-year-effort by the U.S. Fish and Wildlife Service, conservation organizations, and private landowners to protect the remaining pockets of tamaulipan brushland and restore some of what has been lost. The Fish and Wildlife Service has purchased 10,000 acres of cropland and converted it back into tamaulipan woodlands; it hopes to replant another 30,000 acres. The refuge, now totaling 98,000 acres, has been likened to a string of pearls, with connected jewels of old-growth and restored habitat adorning the 300-mile lower Rio Grande Valley.

      Into this carefully rebuilt wildlife corridor now comes the disruption of a flurry of new border wall construction. Scientists and conservationists across Texas warn that it could unravel decades of work to protect the tamaulipan brushland and the wildlife it harbors. “This is the only place in the world you can find this habitat,” says Kersten, a board member of Friends of the Wildlife Corridor, a non-profit group that works closely with the Fish and Wildlife Service on the corridor program. “And only 3 percent of this habitat is remaining.”

      For all its efforts to turn cropland into federally protected habitat, the Fish and Wildlife Service finds itself with little recourse to safeguard it, precisely because it is federal property. The easiest place for the federal government to begin its new wave of border wall construction is the Lower Rio Grande Valley National Wildlife Refuge, which includes the picturesque La Parida Banco tract, where I joined Kersten. Under a 2005 law, the Department of Homeland Security can waive the environmental reviews that federal agencies such as the Fish and Wildlife Service typically conduct for projects that could alter federally protected lands.

      The tract Kersten and I visited is one of four adjacent “pearls” in the wildlife corridor — long , roughly rectangular parcels stretching from an entrance road to the river. From west to east they are the Lower Rio Grande Valley National Wildlife Refuge’s La Parida Banco tract, the Bentsen-Rio Grande Valley State Park, the refuge’s El Morillo Banco tract, and the privately owned National Butterfly Center. A levee runs through all four properties, and the first sections of fence to be built atop it would cut off access to trails and habitat in the refuge tracts. Citizens and local and state officials have successfully fought to keep the fence from crossing the National Butterfly Center, the Bentsen-Rio Grande state park, and the Santa Ana National Wildlife Refuge farther downstream — at least for now. If Trump’s national emergency declaration survives court challenges, the border barriers could even be extended into these holdouts.

      When the wall and access road are completed at La Parida Banco, a crucial piece of intact native habitat will become isolated between the wall and the river. Species that either rely on the river for water or migrate across it will find pathways they’ve traversed for thousands of years blocked.

      While biologists are concerned about the impacts of the wall all along the U.S.-Mexico border, the uniqueness of South Texas’ ecosystems make it an especially troublesome place to erect an 18-foot fence, they say. The 300-mile wildlife corridor in South Texas, where the temperate and the tropical intermingle, is home to an astounding concentration of flora and fauna: 17 threatened or endangered species, including the jaguarundi and ocelot; more than 530 species of birds; 330 butterfly species, about 40 percent of all those in the U.S.; and 1,200 types of plants. It’s one of the most biodiverse places on the continent.

      `There will be no concern for plants, endangered species [and] no consultation with the Fish and Wildlife Service,’ says a biologist.

      “This is a dry land, and when you have dry land, your diversity is near the water,” says Norma Fowler, a biologist with the University of Texas at Austin who studies the tamaulipan brushland ecosystem. She co-authored an article published last year in the scientific journal Frontiers in Ecology and the Environment warning of the consequences of the new wall for the region’s singular ecosystems and wildlife. Since the wall can’t be built in the river, it’s going up a mile or more north of it in some areas, placing both the riparian habitat right along the river and the tamaulipan thornscrub on higher ground at risk.

      “Both of those habitats have been fragmented, and there’s not much left,” Fowler says. “Some of it is lovingly restored from fields to the appropriate wild vegetation. But because they’ve waived every environmental law there is, there will be no concern for plants, endangered species. There will be no consultation with the Fish and Wildlife Service.”

      When the wall rises, the barrier and the new patrol road alongside it will cut an unusually wide 140-foot swath to improve visibility through the dense brush. In her article, Fowler estimated that construction of the border wall would destroy 4.8 to 7.3 acres of habitat per mile of barrier. The fence will also cut off access to the river and habitat on the Mexican side of the border for many animals. Including bobcats, ocelot, jaguarundi, and javelina. Some slower-moving species, like the Texas tortoise, could be caught in floods that would swell against the wall.

      If new walls must be built along the Rio Grande, Fowler says, the Department of Homeland Security should construct them in a way that causes the least harm to wildlife and plants. That would include limiting the footprint of the access roads and other infrastructure, designing barriers with gaps wide enough for animals to pass through, and using electronic sensors instead of physical barriers wherever possible.

      One of the most at-risk species is the ocelot, a small jaguar-like cat that historically roamed throughout Texas, Arkansas, Louisiana, and Arizona, but that numbers only about 80 today. The sole breeding population left in the U.S. is in South Texas, and it is wholly dependent on the dense shrubland in the Lower Rio Grande Valley that the wall will bisect. Some species could be wiped out altogether: The few sites where Physaria thamnophila, a native wildflower, still grows are directly in the path of the wall, Fowler says.

      With 1,254 miles of border — all following the languid, meandering course of the Rio Grande — Texas has far more of the United States’ 1,933-mile southern boundary than any other state, yet it has the fewest miles of existing fence. That’s because much of the Texas border is private riverfront land. The first major push to barricade the Texas border, by the George W. Bush administration, encountered opposition from landowners who balked at what they saw as lowball purchase offers and the use of eminent domain to take their property. (Years later, some of those lawsuits are still pending.) Federal land managers also put up a fight.

      Natural areas already bisected by a Bush-era fence offer a preview of the potential fate of the Rio Grande wildlife refuge.

      When Ken Merritt — who oversaw the federal South Texas Refuge Complex, which includes the Lower Rio Grande Valley National Wildlife Refuge, Santa Ana, and the Laguna Atascosa refuge near where the Rio Grande meets the Gulf of Mexico — questioned the wisdom of a barrier through Santa Ana during the Bush administration, he was forced out of his job.

      “I was getting a lot of pressure,” says Merritt, who still lives in the valley and is retired. “But it just didn’t fit. We were trying to connect lands to create a whole corridor all along the valley, and we knew walls were very much against that.”

      Natural areas already bisected by the Bush-era fence offer a preview of the potential fate of the Lower Rio Grande Valley National Wildlife Refuge. A few miles downstream from the La Parida tract, the Hidalgo Pumphouse and Birding Center, which anchors the southern end of the tiny town of Hidalgo, now looks out at a stretch of steel bollard fence atop a concrete wall embedded in the levee.

      On a recent Monday morning, a few tourists milled about the gardens behind the pumphouse, listening to the birds — curve-billed thrashers, green monk parakeets, kiskadee flycatchers — and enjoying the view from the observation deck. Curious about the wall, all of them eventually walk up to it and peek through the four-inch gaps between the steel slats. On the other side lies another pearl: a 900-acre riverside piece of the Lower Rio Grande Valley National Wildlife Refuge called the Hidalgo Bend tract. It was once a popular spot with birders drawn to its ferruginous Pygmy owls, elf owls, and other wildlife. But since the wall went up in 2009, few birders visit anymore.

      At The Nature Conservancy’s Sabal Palm Preserve, a 557-acre piece of the wildlife corridor near the Gulf of Mexico, a wall installed in 2009 cuts through one of the last stands of sabal palm forest in the Rio Grande Valley. Laura Huffman, regional director for The Nature Conservancy, worries that the more walls erected on the border, the less hope there is of completing the wildlife corridor.

      Kersten and others remain unconvinced that the danger on the border justifies a wall. She believes that sensors and more Border Patrol agents are more effective deterrents to drug smugglers and illegal immigrants. Earlier on the day we met, Kersten was part of a group of 100 or so protestors who marched from the parking lot at nearby Bentsen-Rio Grande Valley State Park to the adjacent National Butterfly Center, holding signs that read “No Border Wall” and “Solidarity Across Borders.” One placard listed the more than two dozen environmental and cultural laws that the Trump administration waived to expedite the fence. Among them: the National Environmental Policy Act, which requires environmental analysis before federal projects can begin; the Endangered Species Act; the Clean Water Act; the Migratory Bird Treaty Act; the National Wildlife Refuge System Administration Act; the National Historic Preservation Act; and the Native American Graves and Repatriation Act.

      Even as the wall goes up in the refuge, preparations for this year’s restoration projects are moving ahead. Betty Perez, whose family has lived in the Lower Rio Grande Valley for generations, is one of several landowners who grow seedlings for replanting on refuge lands each year. At her ranch, about a 45-minute drive northwest of the La Parida Banco tract, she’s beginning to collect seeds to grow this year’s native shrub crop: coyotillo, in the buckthorn family; yucca; Texas persimmon.

      Next to a shed in her backyard sit rows of seedlings-to-be in white tubes. To Perez, the delicate green shoots hold a promise: In a few years, these tiny plants will become new habitat for jaguarundi, for ocelot, for green jays, for blue herons. Despite the new walls, the wildlife corridor project will go on, she says, in the spaces in between.

    • Border Wall Rising In #Arizona, Raises Concerns Among Conservationists, Native Tribes

      Construction has begun on President Trump’s border wall between Arizona and Mexico, and conservationists are furious. The massive barrier will skirt one of the most beloved protected areas in the Southwest — Organ Pipe Cactus National Monument, recognized by the United Nations as an international biosphere reserve.

      On a recent drive along the borderline, a crew was transplanting tall saguaro cactus out of the construction zone.

      “There may be misconceptions that we are on a construction site and just not caring for the environment,” intones a voice on a video released by the U.S. Army Corps of Engineers, which is overseeing the project. “We are relocating saguaro, organ pipe, ocotillo...”

      But a half-mile away, a big yellow bulldozer was scraping the desert clean and mowing down cactus columns that were likely older than the young man operating the dozer.

      Customs and Border Protection later said 110 desert plants have been relocated, and unhealthy ones get bulldozed.

      This scene illustrates why environmentalists are deeply skeptical of the government’s plans. They fear that as CBP and the Defense Department race to meet the president’s deadline of 450 miles of wall by Election Day 2020, they will plow through one of the most biologically and culturally rich regions of the continental United States.

      The U.S. Fish & Wildlife Service has warned that the wall, with its bright lights, human activity and impermeable barrier, could negatively impact 23 endangered and at-risk species, including the Sonoran pronghorn antelope. And the National Park Service says construction could destroy 22 archaeological sites. Yet, for this stretch of western desert, the government has waived 41 federal environmental laws to expedite construction.

      “This is a wall to fulfill a campaign promise. It’s really clear. And that’s what makes so many of us so angry. It’s being done so fast outside the rule of law and we know it’ll have an incredible impact,” says Kevin Dahl, Arizona representative for the National Parks Conservation Association. He sits beside a serene, spring-fed pond fringed by cattails, and dive-bombed by dragonflies. It is called Quitobaquito Springs, and it’s located on the southern edge of the #Organ_Pipe_Cactus_National_Monument.

      A biologist peers into a rivulet that feeds this oasis in the middle of the Sonoran desert.

      “These guys are very tiny, maybe half the size of a sesame seed. Those are the Quitobaquito tryonia. And there are literally thousands in here,” says Jeff Sorensen, wildlife specialist supervisor with Arizona Game and Fish Department. He’s an expert on this tiny snail, which is one of three species — along with a mud turtle and a pupfish — whose entire universe is this wetland.

      The springs have been used for 16,000 years by Native Americans, followed by Spanish explorers, traders and farmers.

      But the pond is a stone’s throw from the international border, and the path of the wall. Conservationists fear workers will drill water wells to make concrete, and lower the water table which has been dropping for years.

      “We do have concerns,” Sorensen continues. “Our species that are at this site rely on water just like everything else here in the desert southwest. And to take that water away from them means less of a home.”

      The Trump administration is building 63 miles of wall in the Tucson Sector, to replace outdated pedestrian fences and vehicle barriers. CBP says this stretch of desert is a busy drug- and human-trafficking corridor. In 2019, the Tucson sector had 63,490 apprehensions and seized more than 61,900 pounds of illegal narcotics. The Defense Department is paying Southwest Valley Constructors, of Albuquerque, N.M., to erect 18- to 30-foot-tall, concrete-filled steel bollards, along with security lights and an all-weather patrol road. It will cost $10.3 million a mile.

      The rampart is going up in the Roosevelt Reservation, a 60-foot-wide strip of federal land that runs along the U.S. side of the border in New Mexico, Arizona and California. It was established in 1907 by President Theodore Roosevelt.

      Congress refused to authorize money for construction of the wall in Arizona. Under Trump’s national emergency declaration, the Defense Department has reprogrammed counterdrug funding to build the border wall.

      In responses to questions from NPR, CBP says contractors will not drill for water within five miles of Quitobaquito Springs. The agency says it is coordinating with the National Park Service, Fish & Wildlife and other stakeholders to identify sensitive areas “to develop avoidance or mitigation measures to eliminate or reduce impacts to the environment.” Additionally, CBP is preparing an Environmental Stewardship Plan for the construction project.

      Critics are not appeased.

      “There is a whole new level of recklessness we’re seeing under Trump. We thought Bush was bad, but this is a whole other order of magnitude,” says Laiken Jordahl, a former national park ranger and now borderlands campaigner with the Center for Biological Diversity.

      There was an outcry, too, back in the late 2000s when President George W. Bush built the first generation of bollard wall. Those barriers topped out at 18 feet. The structures rising southwest of Tucson are as tall as a two-story building. They look like they could hold back a herd of T-rexes.

      The Trump administration is using the same Real ID Act of 2005 that empowered President George W. Bush to build his border wall without heeding environmental protections. But the pace of waivers is quickening under Trump’s aggressive construction timeline. Under Bush, the Department of Homeland Security issued five waiver proclamations. Under Trump, DHS has issued 15 waivers that exempt the contractors from a total of 51 different laws, ranging from the Clean Water Act to the Archeological Resources Protection Act to the Wild Horse and Burro Act.

      “The waivers allow them to bypass a lot of red tape and waive the public input process,” says Kenneth Madsen, a geography professor at Ohio State University at Newark who monitors border wall waivers. “It allows them to avoid getting bogged down in court cases that might slow down their ability to construct border barriers along the nation’s edges.”

      The most important law that CBP is able to sidestep is the National Environmental Policy Act, NEPA—known as the Magna Carta of federal environmental laws. It requires a detailed environmental assessment of any “federal actions significantly affecting the quality of the human environment.” NEPA covers most large federal construction projects, such as dams, bridges, highways, and waterway projects.

      Considering the construction of 450 miles of steel barriers on the nation’s southern boundary, “There is no question that NEPA would require preparation of an environmental impact statement, with significant input from the public, from affected communities, tribal governments, land owners, and land managers throughout the process. And it is outrageous that a project of this magnitude is getting a complete exemption from NEPA and all the other laws,” says Dinah Bear. She served as general counsel for the White House’s Council on Environmental Quality for 24 years under four presidents.

      To some border residents, barriers — regardless how controversial — are the best way to stop illegal activity.

      “I support Donald Trump 100%. If you’re going to build a wall, build it!” declares rancher John Ladd.

      His family has bred cattle in Arizona since it was a territory. Their ranch backs up to the Mexican border near the town of Naco. The surrounding mountains purple at dusk, as a bull and his harem of cows munch gramma grass.

      Time was when the Ladd ranch was overrun by people crossing the border illegally. They stole things and cut fences and left trash in the pastures. Then in 2016, at the end of the Obama years, CBP built a fence, continuing what Bush started.

      Ladd reserves judgment on the propriety of a wall through a federally protected wilderness. But for his ranch, walls worked.

      “When this 18-foot wall went in, it was obvious that immigrants quit coming through here,” he says. “It was an immediate improvement with the security of our border as well as our houses.”

      Other border neighbors feel differently.

      The vast Tohono O’odham Nation — nearly as big as Connecticut — shares 62 miles with Mexico. The tribe vehemently opposes the border wall. Several thousand tribal members live south of the border, and are permitted to pass back and forth using tribal IDs.

      Already, border barriers are encroaching on the reservation from the east and west. While there is currently no funding to wall off the Arizona Tohono O’odham lands from Mexico, tribal members fear CBP could change its mind at any time.

      “We have lived in this area forever,” says Tribal Chairman Ned Norris, Jr. “And so a full-blown 30-foot wall would make it that much difficult for our tribal citizens in Mexico and in the U.S. to be able to actively participate with family gatherings, with ceremonial gatherings.”

      Traditions are important to the Antone family. The father, son and daughter recently joined other tribal members walking westward along State Highway 86, which runs through the reservation. They were on a pilgrimage for St. Francis.

      Genae Antone, 18, stopped to talk about another rite of passage. Young Tohono O’odham men run a roundtrip of 300 miles from the reservation, across the border, to the salt flats at Mexico’s Sea of Cortez.

      “The salt run, for the men, that’s really important for us as Tohono O’odham. For the men to run all the way to the water to get salt,” she said. “Some people go and get seashells. So I don’t really necessarily think it (the border wall) is a good idea.”

      The Antone family — carrying a feathered walking stick, a statue of the virgin, and an American flag — then continued on its pilgrimage.

    • Les murs frontaliers sont une catastrophe écologique

      On les croyait en voie d’extinction, ils se sont multipliés : les murs et autres clôtures aux frontières pour empêcher les migrations humaines ont un impact délétère sur de nombreuses espèces en morcelant leurs habitats naturels. Une raison de plus de s’y opposer, pour ce chroniqueur de gauche britannique.

      C’est au XXIe siècle que convergent les catastrophes humanitaires et environnementales. L’effondrement climatique a contraint des millions de personnes à fuir de chez elles, et des centaines de millions d’autres risquent le même sort. La famine qui dévaste actuellement Madagascar est la première que les Nations unies ont qualifiée de conséquence probable de l’urgence climatique [un lien contesté] ; elle ne sera pas la dernière. De grandes métropoles s’approchent dangereusement de la pénurie d’eau à mesure que les nappes souterraines sont vidées. La pollution de l’air tue 10 millions de personnes par an. Les produits chimiques de synthèse qui se trouvent dans les sols, l’air et l’eau ont des retentissements indicibles sur les écosystèmes et les êtres humains.

      Mais, à l’inverse, les catastrophes humanitaires, ou plus précisément les réactions cruelles et irrationnelles des gouvernements face à ces crises, peuvent aussi déclencher des désastres écologiques. L’exemple le plus frappant est la construction de murs frontaliers.

      En ce moment, avec l’aide de 140 ingénieurs militaires britanniques, la Pologne entame la construction d’une paroi en acier de 5,5 mètres de haut sur 180 kilomètres, le long de sa frontière avec la Biélorussie. L’aide des militaires britanniques facilitera la signature d’un nouveau contrat d’armement entre le Royaume-Uni et la Pologne, d’un montant approximatif de 3 milliards de livres.
      L’illusion de la chute du mur

      Le mur est présenté comme une mesure de “sécurité”. Pourtant, il protège l’Europe non pas d’une menace mais du dénuement absolu de personnes parmi les plus vulnérables du monde, en particulier des réfugiés venus de Syrie, d’Irak et d’Afghanistan qui fuient les persécutions, la torture et les massacres. Ils ont été cruellement exploités par le gouvernement biélorusse, qui s’est servi d’eux comme arme politique. Ils sont maintenant piégés à la frontière en plein hiver, gelés et affamés, sans nulle part où aller.

      À la chute du mur de Berlin, on nous a promis l’avènement d’une nouvelle époque plus libre. Depuis, beaucoup plus de murs ont pourtant été érigés qu’abattus. Depuis 1990, l’Europe a construit des murs frontaliers six fois plus longs que celui de Berlin. À l’échelle mondiale, le nombre de frontières clôturées est passé de 15 à 70 depuis la fin de la guerre froide : il existe actuellement 47 000 kilomètres de frontières matérialisées par des barrières.

      Pour ceux qui sont piégés derrière ces obstacles, la cruauté du capitalisme est difficile à distinguer de la cruauté du communisme.

    • An endangered wolf spent days searching for a mate. The border wall blocked him.

      It is the first time researchers have directly observed how border fences hinder the Mexican gray wolf, which is on the verge of extinction.

      One chilly early morning in November, a wolf roamed southwest of Las Cruces, New Mexico, on the southern border of the U.S. He was probably driven by the call for survival and wanted to mate, researchers say.

      In his search for a mate or for better opportunities, the wolf tried to cross the dangerous Chihuahuan Desert, a region he knows very well because it has been his species’ habitat since time immemorial.

      This time, however, he was unable to cross. The barriers that make up the border wall prevented him from crossing the border into Mexico.

      “For five days he walked from one place to another. It was at least 23 miles of real distance, but as he came and went, he undoubtedly traveled much more than that,” said Michael Robinson, the director of the Center for Biological Diversity, a nonprofit organization that defends and monitors species that are in danger of extinction — like this Mexican gray wolf, whom they called Mr. Goodbar.

      Robinson lives in Silver City, very close to Gila National Forest. He noticed the wolf’s adventures when he was reviewing a map from the U.S. Fish and Wildlife Service that records the locations of the wolves using GPS devices they have on necklaces. It is the first time researchers have directly observed how the border wall hinders the life of the species, which is at risk of extinction.

      “Mr. Goodbar’s Thanksgiving was forlorn, since he was thwarted in romancing a female and hunting together for deer and jackrabbits,” Robinson said. “But beyond one animal’s frustrations, the wall separates wolves in the Southwest from those in Mexico and exacerbates inbreeding in both populations.”

      The dangers of the wall

      The Center for Biological Diversity and other organizations have said the border wall cuts off connections for wildlife in the area. The center has filed multiple lawsuits to stop the construction of barriers between the two countries and protect the populations of gray wolves and other endangered animals.

      The organization announced Dec. 21 that it plans to sue the Department of Homeland Security and Customs and Border Protection for failing to protect ocelots and other species during the construction of border levees along the Rio Grande Valley in Texas.

      “It is hypocritical to use safety as an excuse to repair levees and then ignore federal laws that protect people and wildlife. These alleged repairs are seen more as an excuse to rush the construction of the border wall,” Paulo Lopes, a lawyer for the Center for Biological Diversity, said in a statement.

      The organization said more than 13 miles of levees will be built on the land of the Lower Rio Grande Valley National Wildlife Refuge, traversing family farms and other private property in Hidalgo County, Texas.

      Ocelots have been in danger of extinction since 1982, and according to official data, it’s estimated that fewer than 50 of them remain in the U.S., all in South Texas.

      Restoring their habitat, including creating wildlife corridors, is a priority for the Rio Grande Wildlife Refuge, but the levees project — which involves removing vegetation along the river to build a control zone 150 feet wide with new roads for law enforcement agencies, as well as lighting systems, cameras and sensors — threatens the ocelot’s habitat.

      Building a wall on the border between Mexico and the U.S. was one of former President Donald Trump’s main campaign promises, and 450 miles of the project were completed during his presidency. The Biden administration suspended construction work, but Texas’ Republican governor, Greg Abbott, began construction of his own wall on Dec. 20.

      “President Biden should knock down the wall,” Robinson said. “Allowing Mexican gray wolves to roam freely would do right by the sublime Chihuahuan Desert and its lush sky-island mountains. We can’t allow this stark monument to stupidity to slowly strangle a vast ecosystem.”
      Challenges to survival

      By March, the Fish and Wildlife Service had estimated that 186 specimens of the Mexican gray wolf (Canis lupus baileyi) were in the wild, an increase of 14 percent over 2020. The population has increased for five consecutive years. Only 35 of the wolves are in Mexican territory, according to Mexican government data.

      In some ways, the fight to preserve the wolves is a success story, because, from 1915 to 1972, U.S. authorities poisoned and trapped almost all of the wolves in the wild. Three of the last five surviving wolves, captured from 1977 to 1980, were bred in captivity along with the progeny of four previously captured Mexican wolves.

      Because of a lawsuit filed by the center, the descendants of those seven wolves were reintroduced in the Southwestern U.S. in 1998. On the Mexican side, the wolves’ release began in 2011.

      The subspecies is about 5 feet long, usually weighs 50 to 80 pounds and lives in herds of four to nine. Their gray and rust-color fur is abundant. They live from two to eight years, and, despite protective measures, very few die of natural causes.

      Historically, their habitat has been the border: They used to live throughout southwestern Texas, southern New Mexico and southeastern Arizona and as far south as central Mexico. Today they are found only in the Gila ecosystem, in eastern Arizona and western New Mexico, and in the Sierra de San Luis, in northern Mexico.

      Despite the modest but constant growth of its population, activists and experts have made multiple calls to maintain the protections for the species. Mr. Goodbar, who was born at the Sedgwick County Zoo in Kansas and was released in the desert area of ​​Arizona in 2020, is the result of such measures.

      The wolf’s adventurous and exploratory spirit is part of the species’ most basic instincts. It also runs in the family.

      Wolves from Mexico twice entered the U.S. at the beginning of 2017. One crossed through the point where Mr. Goodbar couldn’t make it and then returned to Mexico. Two months later, a female crossed into Arizona, and authorities captured her to appease complaints from people linked to the livestock industry.

      She is Mr. Goodbar’s mother, and she is still in captivity.

      “If the barriers remain on the border, and more are being built, that is going to have an impact on the genetic diversity of the wolves, because it could affect their reproduction. If the wall could be knocked down, at least in some key areas, it has to be done. That will allow for wildlife connectivity,” Robinson said.
      A problem of borders

      Researchers at the Center for Biological Diversity say wolves aren’t the only species threatened by the border wall.

      The telemetry studies of Aaron Flesch, a researcher at the University of Arizona, have found that the mountain owl, a bird in the area, flies at an average height of 4.5 feet, so border fences would also affect it.

      In addition, other animals, such as the cacomixtle, which is similar to a racoon, and the northern fox need to travel through large areas of the Chihuahuan Desert to feed and reproduce, so the barriers are obstacles to their habitats.

      Aislinn Maestas, a public affairs specialist for the Fish and Wildlife Service, said in a statement published in the El Paso Times that it was “speculative” to suggest that a barrier may have affected the wolf’s movements, adding that the wolf has continued to roam widely.

      However, the ecological impacts of border barriers have been widely documented. Roads and farmland isolate wildlife, but nothing else separates some species as effectively as border walls.

      The fence erected between Slovenia and Croatia in 2015 could lead to the gradual extinction of the lynx in the Dinaric Mountains. Carcasses of bears, deer and lynx that died horribly after they got caught on their quills are often found throughout the area.

      The barrier between India and Pakistan has caused the population of the Kashmir markhor (a rare wild goat) to collapse. The world’s longest border fences divide China, Mongolia and Russia, isolating populations of wild donkeys, Mongolian gazelles and other endangered species from the steppes.

      Modern wildlife researchers have warned that even in large protected areas, wildlife species are at risk of extinction if they can’t disperse and mix with populations elsewhere.

      Robinson, the activist, said that only once was he able to see a Mexican gray wolf in the wild. “They are incredible animals and play a key role in balancing nature,” he said.

      After his days trying to cross the border in November, Mr. Goodbar headed north toward Gila National Forest, where most of the Mexican wolves live. The area is very close to where Robinson lives, and he usually hears the powerful howls and sees the footprints the wolves leave on their wanderings across the border.

      “At any moment he will leave again. That is their nature, regardless of the walls that human beings build," Robinson said.

  • 5-decade study reveals fallout from spanking kids - CBS News
    http://www.cbsnews.com/news/5-decade-study-reveals-fallout-from-spanking-kids

    Spanking a child leads to bad behaviors, not the better manners some parents may think a smack on the bottom will elicit, a new study suggests.

    Researchers from the University of Texas at Austin and the University of Michigan analyzed 75 studies involving more than 150,000 children that spanned 50 years.

    This is a wide swath of children and the findings are incredibly consistent,” study author Dr. Elizabeth Gershoff told CBS News. “This shows there is a correlation between spanking and negative outcomes and absolutely no correlation between spanking and positive outcomes.

    Spanking doesn’t make kids behave better right away and it leads to worse behavior in the long run, said Gershoff, an associate professor of human development and family sciences at the University of Texas at Austin. And spanked kids are more likely to be aggressive and antisocial.

      Spanking and Child Outcomes: Old Controversies and New Meta-Analyses.

      Abstract
      Whether spanking is helpful or harmful to children continues to be the source of considerable debate among both researchers and the public. This article addresses 2 persistent issues, namely whether effect sizes for spanking are distinct from those for physical abuse, and whether effect sizes for spanking are robust to study design differences. Meta-analyses focused specifically on spanking were conducted on a total of 111 unique effect sizes representing 160,927 children. Thirteen of 17 mean effect sizes were significantly different from zero and all indicated a link between spanking and increased risk for detrimental child outcomes. Effect sizes did not substantially differ between spanking and physical abuse or by study design characteristics.

  • The Surveillance of Blackness: From the Trans-Atlantic Slave Trade to Contemporary Surveillance Technologies
    http://www.truth-out.org/news/item/35086-the-surveillance-of-blackness-from-the-slave-trade-to-the-police

    as Simone Browne, a professor in the Department of African and African Diaspora Studies at the University of Texas at Austin, demonstrates in her new book Dark Matters: On the Surveillance of Blackness, we can trace the emergence of surveillance technologies and practices back much further, to the trans-Atlantic slave trade.

    You have a large push into affective computing technologies, the kind of machine reading of emotions being used at airports, for example, in Israel, which monitor people for blood pressure, for sweat and for changes in their voice, and then assign a threat category or score to them.

    These kinds of affective computing technologies amp up the role of affect, which, as we know, is something that is socially constructed.

    This gets us to think about: Who gets marked as “angry” prior to any reaction? Again, this harkens back to the controlling images of the “angry Black woman” and the “threatening Black man.” Patricia Hill Collins’ “controlling images” is one of the foundational concepts that continues within sociology and Black feminist theory. It is about social control and the ways in which Black women’s various ways of being become surveilled and stereotyped as a form of social control.

    http://www.theguardian.com/law/2015/dec/09/supreme-court-affirmative-action-fisher-v-university-of-texas

    A US supreme court justice has suggested that black students may benefit from the end of affirmative action admissions policies in US universities because many are “pushed ahead too fast” and should go to “lesser schools” instead.

    The comments by Antonin Scalia came as conservatives on the court gave a sympathetic hearing to a white student who claims she was deprived of a place at the University of Texas due to her race.

    #états-unis #racisme #éducation
    Abigail Fisher graduated two years ago from Louisiana State University instead, but the court was warned that the number of minority students on US college campuses could “plummet” if her appeal against UT is successful – something Scalia suggested could be no bad thing.

  • Je commence un fil sur la « Plaque de Pioneer ». Merci d’avance à tous pour vos contributions !
    Et on commence par Wikipédia, avec deux articles :
    Plaque de Pioneer
    https://fr.wikipedia.org/wiki/Plaque_de_Pioneer

    La plaque de Pioneer est une plaque métallique embarquée à bord de deux sondes spatiales lancées en 1972 et 1973, Pioneer 10 et Pioneer 11, sur laquelle un message pictural de l’humanité est gravé à destination d’éventuels êtres extraterrestres : un homme et une femme représentés nus, ainsi que plusieurs symboles fournissant des informations sur l’origine des sondes.

    Il s’agit en fait d’une sorte de « bouteille à la mer interstellaire », les chances pour qu’elle soit retrouvée étant extrêmement faibles.

    Les sondes Pioneer furent les premiers objets construits par des humains à quitter le système solaire. Les plaques sont attachées aux sondes de manière à être protégées de l’érosion des poussières interstellaires ; si bien que la NASA s’attend à ce que la plaque (et la sonde elle-même) survive plus longtemps que la Terre et le Soleil.

    Un message plus détaillé et évolué, le Voyager Golden Record, est embarqué sous la forme d’un disque vidéonumérique par les sondes Voyager, lancées en 1977.

    Le Voyager Golden Record
    https://fr.wikipedia.org/wiki/Voyager_Golden_Record

    Le Voyager Golden Record est un disque embarqué à bord des deux sondes spatiales Voyager, lancées en 1977. Ce disque de 12 pouces contient des sons et des images sélectionnés pour dresser un portrait de la diversité de la vie et de la culture sur Terre, et est destiné à d’éventuels êtres extraterrestres qui pourraient le trouver.

    Tout comme son précurseur la plaque de Pioneer, il s’agit d’une « bouteille à la mer interstellaire », les chances pour que ces disques soient retrouvés étant extrêmement faibles. De plus, s’ils l’étaient, ce serait dans un futur très lointain : les sondes Voyager ne se retrouveront pas à moins de 1,7 année-lumière d’une autre étoile avant 40 000 ans. Donc, plus qu’une tentative sérieuse de communication avec des extraterrestres, ces disques ont un sens symbolique.

    Sur le couvercle du vidéodisque est gravé le schéma explicatif du mode de lecture ainsi que les symboles inscrits sur la plaque de Pioneer. Le disque lui-même comprend de nombreuses informations sur la Terre et ses habitants, allant des enregistrements de bruits d’animaux et de cris de nourrisson, jusqu’au bruit du vent, du tonnerre, ou d’un marteau-piqueur. Sont aussi compris les enregistrements du mot « Bonjour » dans une multitude de langues, des extraits de textes littéraires et de musique classique et moderne.

    Une source d’uranium 238 (choisi pour sa période radioactive de l’ordre de 4,5 milliards d’années) est également embarquée à bord des sondes, permettant de déterminer le temps écoulé depuis le lancement par datation radioactive.

      On the Critique of Scientific Reason de P. K. Feyerabend
      Dans une note :

      Carl Sagan, surely one of the most imaginative scientists alive warns us not to unduly restrict the possibilities of life, and he mentions various types of ‘chauvinism’ (oxygen-chauvinism: if a planet has no oxygen, then it is uninhabitable; temperature chauvinism: low temperatures such as those on Jupiter and high temperatures such as those on Venus make life impossible; carbon chauvinism: all biological systems are constructed of carbon compounds) which he regards as unwarranted (The Cosmic Connection, New York 1975, Ch. 6). He writes (page 179): “It is not a question of whether we are emotionally prepared in the long run to confront a message from the stars. It is whether we can develop a sense that beings with quite different evolutionary histories, beings who may look far different from us, even ‘monstrous’ may, nevertheless, be worthy of friendship and reverence, brotherhood and trust”. Still, in discussing the question whether the message on the plaque of Pioneer 10 will be comprehensible to extraterrestrial beings he says that “it is written in the only language we share with the recipients: science” (18; cf. p. 217: messages to extraterrestrial beings “will be based upon commonalities between the transmitting and the receiving civilization. Those commonalities are, of course, not any spoken or written language or any common, instinctual encoding in our genetic materials, but rather what we truly share in common — the universe around us, science and mathematics.”) In times of stress this belief in science and its temporary results may become a veritable maniac-making people disregard their lives for what they think to be the truth. Cf. Medvedev’s account of the Lysenko case.

      The Creative Time was launched with EchoStar XVI into outer space an archival disc created by artist Trevor Paglen called The Last Pictures. Made of ultra-archival materials, the disc is expected to orbit the Earth for billions of years affixed to the exterior of the communications satellite. A silicon disc has one hundred photographs selected to represent modern human history.

      The Last Pictures launches with EchoStar XVI satellite

      http://creativetime.org/projects/the-last-pictures

      Since 1963, more than eight hundred spacecraft have been launched into geosynchronous orbit, forming a man-made ring of satellites around the Earth. These satellites are destined to become the longest-lasting artifacts of human civilization, quietly floating through space long after every trace of humanity has disappeared from the planet.
      Trevor Paglen’s The Last Pictures is a project that marks one of these spacecraft with a visual record of our contemporary historical moment. Paglen spent five years interviewing scientists, artists, anthropologists, and philosophers to consider what such a cultural mark should be. Working with materials scientists at Massachusetts Institute of Technology, Paglen developed an artifact designed to last billions of years—an ultra-archival disc, micro-etched with one hundred photographs and encased in a gold-plated shell. In Fall 2012, the communications satellite EchoStar XVI will launch into geostationary orbit with the disc mounted to its anti-earth deck. While the satellite’s broadcast images are as fleeting as the light-speed radio waves they travel on, The Last Pictures will remain in outer space slowly circling the Earth until the Earth itself is no more.

      When scientists confirmed on 12 September that NASA’s Voyager 1 spacecraft had entered
      interstellar space (
      Eos, 94
      (39), 339, doi:10.1002/ 2013EO390003), the probe was acknowledged
      as the first human- made object to travel into that realm. The probe and its twin, Voyager 2, each
      carry a 12-inch gold- plated copper disk, known as the Golden Record.
      The Golden Record is a time capsule containing images, music, and sounds from planet
      Earth that were selected for NASA by a committee chaired by the late astronomer Carl Sagan.
      The Golden Record includes greetings to the universe in 55 different languages. The greeting in

    Ah, Hollywood. Our glowing beacon of modern hope and dreams. But before Hollywood, there was New York, and before New York there was Berlin, Paris, Rome and Greece. History’s most creative people have always flocked to cultural and intellectual hubs, and now, thanks to an amazing visualization from researchers at the University of Texas at Dallas, we can see how that migration has changed over time.

    Last week in the journal Science, the researchers (led by University of Texas at Dallas art historian Maximilian Schich) published a study that looked at the cultural history of Europe and North America by mapping the birth and deaths of more than 150,000 notable figures—including everyone from Leonardo Da Vinci to Ernest Hemingway. That data was turned into an amazing animated infographic that looks strikingly similar to the illustrated flight paths you find in the back of your inflight magazine. Blue dots indicate a birth, red ones means death.

    “The common assumption is that certified juveniles [juveniles 14 and older who have committed felony offenses and are transferred to the adult criminal justice system] are the “worst of the worst,” repeat, violent offenders who are beyond the rehabilitation offered by the juvenile justice system. But is this assumption in fact true? This report examines all available Texas data with respect to certified juveniles and compares them to the population of juveniles who receive determinate sentences and are placed in TYC [the Texas Youth Commission which is part of Texas’ juvenile justice system]. It also compares the significant differences in programming and services for the two populations of juvenile offenders” (p. xi). Sections following an executive summary include: introduction; overview; findings according to numbers of adult certification cases vs. juvenile determinate sentence populations, characteristics of the groups, disposition and sentencing outcomes, and placements and programming; discussion; and recommendations.

  • Stan Liebowitz on copyright and incentives
    http://surprisinglyfree.com/2012/10/16/stan-liebowitz

    Stan Liebowitz, Ashbel Smith Professor of Economics at the University of Texas at Dallas, discusses his paper, “Is Efficient Copyright a Reasonable Goal?” According to Leibowitz, economists could hypothetically calculate the exact copyright terms necessary to incentivize creators to make new works without allowing them to capture “rents,” or profits above the bare minimum necessary. However, he argues, efficiency might not be the best goal for copyright.

    Liebowitz argues from a fairness or justice perspective that society should not favor an economically efficient copyright law, but one that treats creators of copyrighted works the same as workers in other types of industries. In other industries, he argues, workers are allowed to capture and keep rents.
