Source: By Sabrina Imbler, The New York Times. Excerpt: ...The last Xerces blue butterfly was collected in 1941 from Lobos Creek by an entomologist who would later lament that he had killed what was one of the last living members of the species. But was this butterfly truly a unique species? ...Now, researchers have sequenced a near-complete mitochondrial genome of a 93-year-old museum specimen, which suggests the Xerces blue was a distinct species, which they say could be properly named Glaucopsyche xerces, according to a paper published Wednesday in Biology Letters....

[https://www.sciencemag.org/news/2021/05/more-half-caribbean-lizards-and-snakes-disappeared-after-europeans-arrived] - More than half of Caribbean lizards and snakes disappeared after Europeans arrived. Source: By Elizabeth Pennisi, Science Magazine. Excerpt: When European explorers arrived in the Caribbean 500 years ago, they didn’t just upend the lives of the Indigenous people they encountered—they altered the entire ecosystem. As many as 70% of the snakes and lizards living on some islands may have vanished, a new study suggests. And it wasn’t just the colonists that were responsible: It was the cats, rats, and raccoons they brought with them....

2021-03-25. Some Elephants in Africa Are Just a Step From Extinction. By Elizabeth Preston, The New York Times. Excerpt: While some African elephants parade across the savanna and thrill tourists on safari, others are more discreet. They stay hidden in the forests, eating fruit. ...The threat of extinction has diminished the odds of spotting one of these wood-dwelling elephants in recent decades, according to a new [International Union for Conservation of Nature (I.U.C.N)] Red List assessment of African elephants released Thursday. The Red List categorizes species by their risk of forever vanishing from the world. The new assessment is the first in which the conservation union treats Africa’s forest and savanna elephants as two species instead of one. Both are in bad shape. The last time the group assessed African elephants, in 2008, it listed them as vulnerable. Now it says savanna elephants are endangered, one category worse. ...Elephants being killed for their ivory tusks isn’t a new problem, and neither is the habitat loss they face. “It’s the same two main threats that have afflicted the animals forever,” Dr. Gobush said. Poaching comes in waves, she added; it was especially severe in the 1980s and reached another peak in 2011. Where elephants disappear, they leave a big gap — not just physically, but also in the work they do. Some tree species depend entirely on forest elephants to eat their fruits, swallow their large seeds and deposit them elsewhere in a pile of dung....

2021-03-17. Endangered Gazelles Make a Comeback on the Edge of a War Zone. By Carlotta Gall, The New York Times. Excerpt: KIRIKHAN, Turkey — Turkey’s southern border with Syria has become a place of hardship and misery, with tented camps for people displaced by a decade of war on the Syrian side and a concrete wall blocking entrance to Turkey for all but the most determined. Yet amid the rocky outcrops in one small area on the Turkish side, life is abounding as an endangered species of wild gazelle is recovering its stocks and multiplying. The mountain gazelle, a dainty antelope with a striped face and spiraling horns, once roamed widely across the Middle East, and as Roman mosaics reveal, across southern Turkey as well. But by the end of the last century, it was hunted almost to extinction, with only a dwindling population of 2,500 left in Israel, according to the International Union for Conservation of Nature....

2021-02-15. Wildlife trade imperils species, even in protected areas. By Elizabeth Pennisi, Science Magazine. Excerpt: Wildlife trafficking is having a profound negative impact on biodiversity, a new analysis finds. Hunting and trapping to feed international and national trade networks threaten numerous species, the researchers report, even those living in protected areas. “This study adds to the growing body of evidence that commercial wildlife trade is a significant threat,” says Scott Roberton, a conservationist in charge of antitrafficking programs at the Wildlife Conservation Society. Wildlife trafficking is big business, with analysts estimating it generates between $5 billion and $20 billion per year. It involves the capture or killing of tens of millions of individuals from thousands of species, and some 150 million families depend on eating wild animals or selling them for their livelihoods. And although some of this activity is legal, much is illegal. ...the team found the studied species were less abundant if they lived in areas that lacked protection. Without game wardens to enforce quotas or boundaries, for example, populations declined by 65%, the researchers report today in Nature Ecology & Evolution. In areas where animals were traded for food (bushmeat), there was almost a 60% decline in the populations. And in places where animals such as songbirds were being trapped for sale as pets, population declines could reach 73%. In general, “the closer to human settlements the study sites were, the greater the decline in abundance,” Edwards says. In 83 of the 506 examples they studied, the hunted species had disappeared entirely from the study area. But even in protected areas, declines were dramatic, with populations dropping by 39%....

Excerpt: ...It took two years to determine that Myotis nimbaensis, named for the Nimba Mountains where it was discovered, was in fact a new species. The confirmation was published Wednesday in the journal American Museum Novitates. ...At a time when the United Nations has warned of a biodiversity crisis, with 1 million species facing extinction, a find such as this is greeted as a light in a dark era, Bat Conservation International said in a statement. “From a biodiversity standpoint, it’s mostly gloom and doom so it’s always good to have feel-good story,” [Jon] Flanders [the director of endangered species intervention at Bat Conservation International] said....

2021-01-06.  The Last Two Northern White Rhinos On Earth. By Sam Anderson, The New York Times. Excerpt: What will we lose when Najin and Fatu die? ...Sudan was the last male northern white rhinoceros on earth — the end of an evolutionary rope that stretched back millions of years. Although his death was a disaster, it was not a surprise. It was the grim climax of a conservation crisis that had been accelerating, for many decades, toward precisely this moment. Every desperate measure — legal, political, scientific — had already been exhausted. ...Although Sudan was the last male, he was not, actually, the last of his kind. He still had two living descendants, both female: Najin, a daughter, and Fatu, a granddaughter. As Sudan declined, these two stood grazing in a nearby field. They would live out their days in a strange existential twilight — a state of limbo that scientists call, with heartbreaking dryness, “functional extinction.” Their subspecies was no longer viable. Two females, all by themselves, would not be able to save it. In his final moments, Sudan was surrounded by the men who loved him. His caretakers were veterans of the deep bush — not, on any level, strangers to death. ...And yet here it was: March 19, 2018. The men scratched Sudan’s rough skin, said goodbye, made promises, apologized for the sins of humanity. Finally, the veterinarians euthanized him. For a short time, he breathed heavily. And then he died. ...In May 2019, just over a year after the death of Sudan, the United Nations issued an apocalyptic report about mass extinction. One million plant and animal species, it warned, were at risk of annihilation. ...Horns were coveted for all kinds of reasons: as trophies, as tools reputed to detect poison and ease childbirth, as the raw material for decorative Yemeni dagger handles. And perhaps most notorious, as an ingredient in traditional Chinese medicine, whose practitioners believe that powdered rhino horn can perform a long list of marvels: It can cool the blood, ease headaches, stop vomiting, cure snakebites and much more....

2020-12-17. Ivory From Shipwreck Reveals Elephant Slaughter During Spice Trade. By Rachel Nuwer, The New York Times. Excerpt: In 2008, workers searching for diamonds off the coast of Namibia found a different kind of treasure: hundreds of gold coins mixed with timber and other debris. They had stumbled upon Bom Jesus, a Portuguese trading vessel lost during a voyage to India in 1533. Among the 40 tons of cargo recovered from the sunken ship were more than 100 elephant tusks. More than a decade after the ship’s discovery, a team of archaeologists, geneticists and ecologists have pieced together the mystery of where the tusks came from and how they fit into the overall picture of historical ivory trade. The researchers’ analysis also revealed that entire elephant lineages have likely been wiped out since the Bom Jesus set sail, shining a light on the extent to which humans have decimated a species once found in far greater numbers across large parts of the African continent....

Excerpt: The monarch butterfly is threatened with extinction, but will not come under federal protection because other species are a higher priority, federal officials announced Tuesday. ...But their numbers have been decimated by climate-change-fueled weather events and pervasive habitat loss in the United States. ...The number of Eastern monarchs — which undertake an astonishing, multigenerational migration from as far north as Canada to overwinter in central Mexico — has declined by 75 percent since the 1990s, scientists estimate. Across the Rocky Mountains, Western monarchs have seen an even more alarming drop. Some of this collapse is tied to a need for milkweed, the only plant that monarch caterpillars can eat. Milkweed has declined across monarch breeding grounds throughout the United States since farmers started using crops that are genetically modified to tolerate Roundup, a brand of weedkiller. Milkweed often grew among crops, but cannot survive spraying....

2020-12-10. Tasmanian devils claw their way back from extinction. By Elizabeth Pennisi, Science Magazine. Excerpt: For decades a ghastly facial cancer has been decimating Tasmanian devils. Spreading from animal to animal when the stocky, raccoon-size marsupials bite each other, the transmissible cancer has killed up to 80% of the devils in Tasmania, their only home for millennia. Some researchers saw extinction as inevitable. Now, a new study in Science, suggests the remaining 15,000 devils have reached a détente with the cancer. Until recently it was spreading exponentially, like the pandemic coronavirus among humans in many parts of the world. But geneticists calculate that each infected devil now transmits tumor cells to just one—or fewer—other devils. That could mean the disease may disappear over time....

Excerpt: ...In a study published in August in Conservation Biology, Dr. Frances and 15 other researchers from across the United States quantified how many trees, shrubs, herbs and flowering plants have vanished from North America since European settlement. After compiling existing information on presumed extinct species and working with local botanists to vet the data, the group narrowed down a list of 65 plant species, subspecies and varieties that have been lost forever in the wild. That figure is almost certainly an underestimate, said Wes Knapp, a botanist at the North Carolina Natural Heritage Program and a co-author of the study....

2020-10-04. ‘David Attenborough: A Life on Our Planet’ Review: Ruin and Regrowth. By Natalia Winkelman, The New York Times. Excerpt: The majestic documentary “David Attenborough: A Life on Our Planet” opens with its title subject standing in a deserted location. It’s the territory around the Chernobyl nuclear plant, a once buzzing area that was evacuated after human error rendered it uninhabitable. ...Calling the film (streaming on Netflix) his “witness statement” for the environment, David Attenborough goes on to trace his more than 60-year career as a naturalist, mapping how steeply the planet’s biodiversity has degenerated before him. Global air travel was new when he began his work, and footage of him as a young producer encountering exotic flora and fauna lends a moving, even haunting, note to his plea to restore ecological balance. ...upsetting is the loss of rain forests, showcased through the stark cutoff between flourishing vegetation and uniform rows of oil palms planted for profit. Such cinematic juxtapositions are persuasive: A dying planet is an ugly one, while healthy ecosystems please the eye and the earth. ...The most devastating sequence finds Attenborough charting the disasters we face in future decades — global crises that he, as a man now in his 90s, will not experience. Yet he finds hope by extrapolating small successes. Sustainable farming in the Netherlands has made the country one of the worldwide leaders in food exports. ...The film’s grand achievement is that it positions its subject as a mediator between humans and the natural world. Life cycles on, and if we make the right choices, ruin can become regrowth.... [https://www.nytimes.com/2020/10/04/movies/david-attenborough-a-life-on-our-planet-review.html]  


2020-09-15. A ‘Crossroads’ for Humanity: Earth’s Biodiversity Is Still Collapsing. By Catrin Einhorn, The New York Times. Excerpt: The world is failing to address a catastrophic biodiversity collapse that not only threatens to wipe out beloved species and invaluable genetic diversity, but endangers humanity’s food supply, health and security, according to a sweeping United Nations report issued on Tuesday. When governments act to protect and restore nature, the authors found, it works. But despite commitments made 10 years ago, nations have not come close to meeting the scale of the crisis, which continues to worsen because of unsustainable farming, overfishing, burning of fossil fuels and other activities. “Humanity stands at a crossroads,” the report said. It comes as the devastating consequences that can result from an unhealthy relationship with nature are on full display: A pandemic that very likely jumped from bats has upended life worldwide, and wildfires, worsened by climate change and land management policies, are ravaging the American West. “These things are a sign of what is to come,” said David Cooper, an author of the report and the deputy executive secretary of the United Nations Convention on Biological Diversity, the global treaty underlying the assessment. “These things will only get worse if we don’t change course.”....

2020-07-31. With powerful LED flashlights, humans are upping their jungle kills. By Warren Cornwall, Science Magazine. Excerpt: Cheap, powerful flashlights are allowing hunters in tropical jungles around the world to more easily kill nocturnal animals, including endangered species such as pangolins, according to a new study. Scientists warn the new technology threatens to further damage ecosystems already strained by overhunting. Humans have stalked their prey with bright lights such as flashlights for decades. Sudden illumination can cause animals to freeze, making them easier targets. But flashlights using conventional incandescent bulbs quickly run out of power, making such hunting costly and difficult. By comparison, light-emitting diode (LED) flashlights—which emit light from tiny electronic chips—can provide a burst of light while using less than one-quarter of the power. Their efficiency and brightness has made them ubiquitous in everything from TVs to cellphones over the past decade. Mark Bowler, an ecologist at the University of Suffolk, wondered whether the technology might also be changing the way people hunt in the jungles of the Peruvian Amazon, where he studies animal ecology. ...He joined researchers in Brazil and Gabon to gather data from hunters about their use of such lights. The results confirmed his suspicions. Of 120 hunters, nearly all reported using LED lights, Bowler and colleagues report this week in Frontiers in Ecology and the Environment. In South America, two-thirds of the hunters said they did more nighttime hunting with the new flashlights; in Gabon, where such hunting is illegal, just one-third said they did more night hunting. More than half the hunters said the LEDs made hunting easier.... [https://www.sciencemag.org/news/2020/07/powerful-led-flashlights-humans-are-upping-their-jungle-kills].

2020-06-05. Elephants, Long Endangered by Thai Crowds, Reclaim a National Park. By Hannah Beech and Muktita Suhartono, The New York Times. Excerpt: KHAO YAI, Thailand — For as long as the elephants could remember — and that is a long time — the path to the river snaked down the hillside through jungle so dense a troop of pachyderms could simply vanish. But about three decades ago, humans decided they, too, wanted to get to the river, to gaze at the waterfalls that cascaded into the Khao Yai National Park in central Thailand. The humans paved over part of the elephants’ trail with cement. They built toilets and snack kiosks. The elephants, though, still needed to reach the river. They hewed close to the old route, the one imprinted on generations of pachyderm brains, but not so close that the day-trippers, with their picnics of sticky rice and grilled pork, would see them. It was a fatal diversion. The new trail passed a cliff and an area prone to flash floods. Elephant after elephant drowned. Last October, a baby elephant fell into the roiling waters. Others charged in to save the calf. All told, 11 elephants died. Since the coronavirus pandemic accelerated in March, Khao Yai, Thailand’s oldest national park, has been closed to human visitors for the first time since it opened in 1962. Without the jeeps and the crowds, the park’s 300 or so elephants have been able to roam freely, venturing onto paths once packed with humans. Rarely spotted animals, like the Asian black bear or the gaur, the world’s largest bovine, have emerged, too....

2020-06-01. Mass Extinctions Are Accelerating, Scientists Report. By Rachel Nuwer. The New York Times. Excerpt: We are in the midst of a mass extinction [https://www.nature.com/articles/nature09678], many scientists have warned — this one driven not by a catastrophic natural event, but by humans. The unnatural loss of biodiversity is accelerating, and if it continues, the planet will lose vast ecosystems and the necessities they provide, including fresh water, pollination, and pest and disease control. On Monday, there was more bad news: We are racing faster and closer toward the point of collapse than scientists previously thought, according to research published in the Proceedings of the National Academy of Sciences. The extinction rate among terrestrial vertebrate species is significantly higher than prior estimates, and the critical window for preventing mass losses will close much sooner than formerly assumed — in 10 to 15 years. ...The current rate of extinctions vastly exceeds those that would occur naturally, Dr. Ceballos and his colleagues found. Scientists know of 543 species lost over the last 100 years, a tally that would normally take 10,000 years to accrue....

2020-05-22. Would you pay to save this creature? Fake beasties reveal why some animals get conservation bucks. By Amanda Heidt, Science Magazine. Excerpt: [Image caption: Donors were more likely to pay to conserve this large and colorful imaginary beast, compared with its less vibrant cousins.] ...it is the winner of a new competition, which used drawings of imaginary animals to deduce which real ones have the power to bring in the big conservation bucks. The upshot: Although it doesn’t hurt to be cute, it’s not the only thing that matters. Researchers already know people tend to support animals they find adorable. That’s why it’s easier to raise money to save pandas than bats. But no one knows exactly which features—both the physical and the nonphysical kind—motivate donors. “Donations are really key to a lot of institutions,” from zoos to nonprofits, says Diogo Veríssimo, a conservation biologist with the nonprofit San Diego Zoo Global, who was not involved in the study. “Without them, many of the largest conservation organizations would struggle to survive.” ...To understand which features people find most appealing, Papworth asked hundreds of past conservation donors to rank her imaginary species for attractiveness, taking note of what they did (or didn’t) like. Then, she used a smaller subset of only the most and least popular animals to ask a similar but distinct question: Which creatures would people pay to conserve? Imaginary animals that were larger, more colorful, or dominated by cooler tones such as blues and purples were most likely to solicit donations, the team reported recently in Conservation Letters. On average, participants were 37% more likely to donate to animals with at least one such feature; they were particularly drawn to more colorful species. To be sure their findings weren’t limited to imaginary beasties, the team then gave 50 cents to each person to donate to real animal charities. Charities raising funds for tigers, the most popular choice, received six times the donations of charities for species such as sharks and bats, supporting most of Papworth’s conclusions....

Excerpt: Since South Africa announced a national lockdown on March 23 to limit the spread of the new coronavirus, Mr. Jacobs has had to respond to a rhino poaching incident nearly every day. On March 25, he rescued a 2-month-old white rhino calf whose mother had been killed by poachers. The next day he was called to rescue two black rhinos whose horns had been hacked off by poachers. When he finally tracked them down it was too late — both were dead. ...At least nine rhinos have been poached in South Africa’s North West province since the lockdown, he said, “and those are just the ones we know about.” ...In neighboring Botswana, according to Rhino Conservation Botswana, a nonprofit organization, at least six rhinos have been poached since the country closed its borders to stop the spread of Covid-19. And last week, the country’s government announced that five suspected poachers had been killed by Botswana’s military in two separate incidents. While poaching is not unusual in Africa — the last decade has seen more than 9,000 rhinos poached — conservationists said the recent incidents in Botswana and South Africa were unusual because they occurred in tourism hot spots that, until now, were considered relatively safe havens for wildlife....

2014-09-25. Gray wolves back on the protected list in Wyoming. The resurgence of gray wolves, especially in Yellowstone National Park, is often held up as a great success in conservation. Indeed, so successful was the effort that in 2012 the U.S. Fish and Wildlife Service declared the wolf population to be stable enough for the species to be delisted. However, since that time, 219 wolves have been killed out of an estimated 1600 in the state of Wyoming, The Dodo reports, thanks to a state-enacted “kill-on-sight approach to wolf management.” In response, a U.S. district judge ruled this week that the endangered species protections for gray wolves would be reinstated—a decision praised by conservationists. http://news.sciencemag.org/sifter/2014/09/gray-wolves-back-on-the-protected-list-in-wyoming.

Two Death Valley plants saved by the Endangered Species Act.    Excerpt: Eureka Dunes, a towering expanse of shifting slopes wedged between weathered mountains in the Mojave Desert, had a reputation as a campground, an off-road vehicle course and a home to a few plant species found no place else on Earth. In the late 1970s, the dunes earned a reputation as an area where the Eureka Valley evening primrose and Eureka dune grass were listed as federally endangered species to protect them from being driven to extinction by off-road vehicle recreation.

The park was recognized as a UNESCO Biosphere Preserve in 1977 and a World Heritage Site in 1987. ...The researchers attribute Manu National Park's remarkable species diversity to its large area and steep topographic variation. The park only represents an estimated 0.01 percent of the Earth's land area, but is home to 2.2 percent of all amphibians and 1.5 percent of all reptiles known worldwide, the biologists said. The park's biodiversity is threatened, however, by the chytrid fungus, which has caused a decline in the number of frogs there, .... Deforestation for subsistence living, gold mining and oil and gas drilling are encroaching on the buffer zone around the park, the researchers said in a statement, noting that these pose threats not just to wildlife, but to the indigenous tribes that call the park home. http://www.natureworldnews.com/articles/6113/20140220/perus-manu-national-park-home-amphibians-reptiles-earth-video.htm.  [VIDEO] By James A.

2013-10-15.  Moose Die-Off Alarms Scientists.   Excerpt: ...Across North America — in places as far-flung as Montana and British Columbia, New Hampshire and Minnesota — moose populations are in steep decline. And no one is sure why. ...Several factors are clearly at work. But a common thread in most hypotheses is climate change. Winters have grown substantially shorter across much of the moose’s range. In New Hampshire, a longer fall with less snow has greatly increased the number of winter ticks, a devastating parasite. “You can get 100,000 ticks on a moose,” said Kristine Rines, a biologist with the state’s Fish and Game Department.  In Minnesota, the leading culprits are brain worms and liver flukes. Both spend part of their life cycles in snails, which thrive in moist environments. Another theory is heat stress. Moose are made for cold weather, and when the temperature rises above 23 degrees Fahrenheit in winter, as has happened more often in recent years, they expend extra energy to stay cool. That can lead to exhaustion and death. ...Unregulated hunting may also play a role in moose mortality. So may wolves in Minnesota and the West.... http://www.nytimes.com/2013/10/15/science/earth/something-is-killing-off-the-moose.html. Jim Robbins, The New York Times.

2013-06-10.  A Glamorous Killer Returns. Excerpt:  ... about seven feet long, nose to tail, and weighed up to 160 pounds. Given a dietary choice, they preferred deer, but would eat almost anything that moved: elk, bighorn sheep, wild horses, beaver, even porcupines. Left free for an evening, they were capable of killing a dozen domestic sheep before dawn, eating their fill and leaving the rest for the buzzards. They were also known to attack humans on occasion. Long ago the Inca called them puma, but today — though they belong to only one species — they have many names. In Arizona they are known as mountain lions; in Florida they are panthers, and elsewhere in the South they are called painters. When they roamed New England, they were called catamounts. In much of the Midwest they are known as cougars, .... All but exterminated east of the Rockies by 1900, they were treated as “varmints” in most Western states until the late ’60s and could be shot on sight. In Maine, the last catamount was killed in 1938. But today Puma concolor is back on the prowl. That is one of the great success stories in wildlife conservation, but also a source of concern among biologists and other advocates, for their increasing numbers make them harder to manage — and harder for people to tolerate. No reliable estimate exists for the cougar population at its lowest point, before the 1970s, but there are now believed to be more than 30,000 in North America. They have recolonized the Black Hills of South Dakota, the North Dakota Badlands and the Pine Ridge country of northwestern Nebraska. ...And as cougars migrate eastward, they are likely to wear out their welcome. People in states unaccustomed to these outsize prowlers will have to answer unpleasant questions: How many livestock and game animals are people willing to lose? How dangerous are cougars to pets and children? How much disruption is a small community willing to endure?....  http://www.nytimes.com/2013/06/11/science/cougars-glamorous-killers-expand-their-range.html. Guy Gugliotta, New York Times.

2013-06-07.  Gray wolves to be removed from endangered species list.  Excerpt: Gray wolves no longer face the threat of extinction, according to the U.S. Fish and Wildlife Service. Calling the recovery “one of the most remarkable success stories in the history of conservation," FWS Director Dan Ashe announced today the agency is proposing to remove all of the nation's wolves from the endangered species list, turning management over to states. Federal protection will remain for the Mexican wolf. ...in most states they'll still be under state-level endangered species protection. “No one suggests that gray wolves don’t require management,” Ashe said in a teleconference on Friday. “The issue is whether gray wolves still require federal protection under the endangered species act, and we believe quite clearly they do not." Friday’s de-listing proposal is already being questioned by some environmentalists who view the move as premature. “Wolves currently inhabit only a fraction of their former range, and this proposal will cut off wolf recovery from vast areas of suitable habitat out west where the species can still thrive,” Jamie Rappaport Clark, president of Defenders of Wildlife, said in a press release. But Ashe firmly told reporters at the teleconference that for wolves to be considered recovered, they do not need to occupy most or all of their historic range. He also said he expected to see wolves continue to expand into northern California, Utah, Nevada and Colorado under state management. Center for Biological Diversity’s endangered species director, Noah Greenwald, worried states would kill too many wolves under their management plans. ...Officials need to keep the total number of wolves around 140, with at least 10 breeding pairs, to avoid a re-listing.... http://www.hcn.org/blogs/goat/gray-wolves-to-be-removed-from-endangered-species-list.

Monk seals are easy targets. After the Polynesians landed in Hawaii, about 1,500 years ago, the animals mostly vanished, slaughtered for meat or oil or scared off by the settlers’ dogs. But the species quietly survived in the Leeward Islands, northwest of the main Hawaiian chain — a remote archipelago, .... There are now about 900 monk seals in the Leewards, and the population has been shrinking for 25 years, making the seal among the world’s most imperiled marine mammals. The monk seal was designated an endangered species in 1976. Around that time, however, a few monk seals began trekking back into the main Hawaiian Islands — “the mains” — and started having pups. These pioneers came on their own, oblivious to the sprawling federal project just getting under way to help them. Even now, recovering the species is projected to cost $378 million and take 54 years. ...The animals have been met by many islanders with a convoluted mix of resentment and spite. This fury has led to what the government is calling a string of “suspicious deaths.”   ....

2013-03-05.  Conservationists say online ivory trade poses threat to African elephants | Associated Press.  Excerpt: BANGKOK — Conservationists say there’s a new threat to the survival of Africa’s endangered elephants that may be just as deadly as poachers’ bullets: the black-market trade of ivory in cyberspace. Illegal tusks are being bought and sold on countless Internet forums and shopping websites worldwide, including Internet giant Google, ...“The Internet is anonymous, it’s open 24 hours a day for business, and selling illegal ivory online is a low-risk, high-profit activity for criminals,” Tania McCrea-Steele of the International Fund for Animal Welfare told The Associated Press ...IFAW found 17,847 elephant products listed on 13 websites in China. ...illegal ivory trading online is an issue within the U.S., including on eBay, and it is rife on some websites in Europe, particularly nations with colonial links to Africa. It is often advertised with code words like “ox-bone,” ‘’white gold,” ‘’unburnable bone,” or “cold to the touch,” and shipped through the mail. Another conservation advocacy group, the Environmental Investigation Agency, said Tuesday that Google Japan’s shopping site now has 10,000 ads promoting ivory sales. About 80 percent of the ads are for “hanko,” small wooden stamps inlaid with ivory lettering that are widely used in Japan to affix signature seals to official documents; the rest are carvings and other small objects. The trade is legal within Japan.... The EIA said hanko sales are a “major demand driver for elephant ivory.” ...About 70 years ago, up to 5 million elephants were believed to have roamed the African continent. Today, just several hundred thousand are left.

2013 February 27. Tusk tracking will tackle illegal trade. By Daniel Cressey, Nature. Excerpt:  International treaties meant to protect elephants are not working. Researchers estimate that tens of thousands of African elephants are now being killed by poachers each year, from a total wild population of around 400,000... Nearly 39,000 kilograms of illegal ivory were traded worldwide in 2011, more than at any other time in the 16-year history of the Elephant Trade Information System (ETIS), which tracks the ivory trade for CITES. Another CITES programme, Monitoring the Illegal Killing of Elephants, will report at the meeting that between 3.5% and 11.7% of the total African elephant population was killed by poachers in 2011 — the worst year for illegal killing since the programme began collecting data in 2002....Poachers in Samburu are also switching focus from males to older females and killing entire social groups, says Wittemyer....Scientists argue that an international drive to trace seized ivory back to its origins is urgently needed, so that authorities can curb poaching before elephant populations collapse. There are few reliable estimates of regional elephant numbers, and counting corpses is inaccurate because many are likely to be lost in the vast forests and savannahs of Africa. A team led by Wasser has developed a map of DNA samples collected across Africa1, 2 — often from elephant dung — which it uses to pinpoint the probable origins of seized ivory samples (see ‘Hunting the poachers’).…. 

2012 October 07. State learns sad lesson with Wedge Pack wolf hunt. By Nicholas K. Geranios, The Seattle Times. Excerpt: …The Wedge Pack of wolves has killed between 40 and 50 head of cattle on his Diamond M Ranch, located near the Canadian border north of Kettle Falls, Stevens County, in Northeastern Washington. That prompted a huge effort by the state Department of Fish and Wildlife to wipe out the pack, less than a year after adopting a plan to recover wolf populations in the state. The Wedge Pack needed to be wiped out because the wolves appeared to have switched from preying on deer, elk and moose and instead were focusing on cattle, state officials said. The expensive hunting effort — which included shooting wolves from helicopters — concluded last week...The hunt was expensive, although the costs have not been tallied yet, Ware said. They include four days of helicopter use, plus weeks of overtime for various state employees, Ware said. He said any future wolf hunts probably will not have to be on this scale....

2012 August 15. Blue iguana breeding program succeeding | by Associated Press, San Francisco Chronicle.  Excerpt: Grand Cayman, Cayman Islands. The blue iguana has lived on the rocky shores of Grand Cayman for at least a couple of million years, preening like a miniature turquoise dragon as it soaked in the sun or sheltered inside crevices. Yet having survived everything from tropical hurricanes to ice ages, it was driven to near-extinction by dogs, cats and cars.
Now, though, a breeding program some see as a global model has worked better than any had hoped to dream for a species that numbered less than a dozen in the wild just a decade ago, preyed upon by escaped pets and struggling to survive in a habitat eroded by the advance of human settlement….

2012 Jun 07. 100 Amazon birds risk extinction, group says. By Jenny Barchfield, Associated Press. Excerpt: The list of Amazon bird species facing danger of extinction has risen sharply because their rainforest habitat is being slashed to make room for cattle ranching and agriculture, a conservationist group said Thursday. BirdLife International said that globally, 1,331 types of birds, or 13 percent of the world's 10,064 total bird species, were listed as at risk on this year's Red List of Threatened Species…The biggest jump came in the Amazon, where 100 Amazon avian species are now on the Red List, three of them in the highest-risk, "critically endangered" category. Only 10 were listed last year. The sudden jump is due to new models of future deforestation, which predicted accelerating destruction over the coming decade. "We have previously underestimated the risk of extinction that many of Amazonia's bird species are facing," said Leon Bennun, BirdLife's director of science, in a news release…"Given the weakening of Brazilian forest law, the situation might be even worse than recent studies have predicted," he said, referring to Brazil's new Forest Code, which loosens protections on the Amazon and is expected to take effect in the coming months.…

2012 May 27. To Save Some Species, Zoos Must Let Others Die. By Leslie Kaufman, The NY Times. Excerpt: As the number of species at risk of extinction soars, zoos are increasingly being called upon to rescue and sustain animals, and not just for marquee breeds like pandas and rhinos but also for all manner of mammals, frogs, birds and insects whose populations are suddenly crashing. To conserve animals effectively, however, zoo officials have concluded that they must winnow species in their care and devote more resources to a chosen few. The result is that zookeepers, usually animal lovers to the core, are increasingly being pressed into making cold calculations about which animals are the most crucial to save. Some days, the burden feels less like Noah building an ark and more like Schindler making a list....

2011 November 11. Western black rhino declared extinct.  By Matthew Knight, CNN News. Excerpt: Africa's western black rhino is now officially extinct according the latest review of animals and plants by the world's largest conservation network.
The subspecies of the black rhino -- which is classified as "critically endangered" by the International Union for Conservation of Nature's (IUCN) Red List of Threatened Species -- was last seen in western Africa in 2006….
...The latest update to the IUCN [International Union for Conservation of Nature] Red List of Threatened Species reviews more than 60,000 species, concluding that 25% of mammals on the list are at risk of extinction. ...Recent studies of 79 tropical plants in the Indian Ocean archipelago revealed that more than three quarters of them were at risk of extinction. In the oceans, the IUCN reports that five out of eight tuna species are now "threatened" or "near threatened"...

2010 Nov 26. The Fight for Yasuni. By Eric Marx, Science. Abstract: Over the past decade, biologists working in Ecuador's Yasuni National Park and the adjoining Waorani Ethnic Reserve, a 17,000-kilometer section of the Amazon Basin that was designated a UNESCO Biosphere Reserve in 1989, have documented Yasuni's remarkable biodiversity, providing evidence that its forest has the highest number of species on the planet, including an unprecedented core where there are overlapping world richness records for amphibians, reptiles, bats, and trees. Through a group called Scientists Concerned for Yasuni, these researchers have waged an international campaign to protect the location, which happens to sit atop Ecuador's second largest reserve of crude oil. This unabashed science-based advocacy has had an impact...

2010 Oct 26 The Impact of Conservation on the Status of the World’s Vertebrates. By Michael Hoffmann et al., Science. Abstract: Using data for 25,780 species categorized on the International Union for Conservation of Nature (IUCN) Red List, we present an assessment of the status of the world’s vertebrates. One-fifth of species are classified as Threatened, and we show that this figure is increasing: On average, 52 species of mammals, birds and amphibians move one category closer to extinction each year. However, this overall pattern conceals the impact of conservation successes, and we show that the rate of deterioration would have been at least one-fifth as much again in the absence of these. Nonetheless, current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups: agricultural expansion, logging, overexploitation, and invasive alien species.

2010 Oct 26. Scenarios for Global Biodiversity in the 21st Century. Henrique M. Pereira, Paul W. Leadley, et al., Science. Abstract: Quantitative scenarios are coming of age as a tool for evaluating the impact of future socioeconomic development pathways on biodiversity and ecosystem services. We analyze global terrestrial, freshwater, and marine biodiversity scenarios using a range of measures including extinctions, changes in species abundance, habitat loss, and distribution shifts, as well as comparing model projections to observations. Scenarios consistently indicate that biodiversity will continue to decline over the 21st century. However, the range of projected changes is much broader than most studies suggest, partly because there are significant opportunities to intervene through better policies, but also because of large uncertainties in projections.

2010 Sep 17. In Search of the Grizzly (if Any Are Left). By William Yardley, The New York Times. Excerpt: PASAYTEN WILDERNESS, Wash. -- “Here,” said Bill Gaines, a wildlife biologist for the Okanogan-Wenatchee National Forest, “is the mother lode.”
Caught on a prong of barbed wire that he had strung weeks earlier in these remote mountains was a tantalizing clue: strands of light brown bear hair.
...Mr. Gaines is leading the most ambitious effort ever to document whether grizzlies still exist here — a century after fur trappers and ranchers killed them off by the hundreds — at a time when tension is high in the West over the fate of wild predators like gray wolves. While many people want the grizzlies, an endangered species, to make a comeback here, others worry that more bears will mean more conflict.
“Grizzlies are a threat to livestock and to humans,” said John Stuhlmiller, the director of government relations at the Washington State Farm Bureau…. People whose livelihoods are not threatened by predators do not get it, Mr. Stuhlmiller said. “If my 401(k) was being raided by grizzly bears, I would think differently,” he said.
…For nearly 30 years the federal government has had a program to help restore the grizzly bear population in Idaho, Montana, Washington and Wyoming. It has made a difference in places like Yellowstone National Park and the Continental Divide region of Montana, but not in the North Cascades, one of six designated recovery zones. Instead, this area has been locked in a virtual standstill as political winds shift over the preservation of large predators.
…Yet small steps are being taken. If the study in the North Cascades proves that grizzlies still live in the area, advocates for recovery will probably face less political opposition. This is because they would be augmenting the historic population, not trying to rebuild the population from scratch when there were no bears at all.

2010 April 29. World's 2010 nature target 'will not be met'. By Richard Black, BBC News. Excerpt: The world's governments will not meet their internationally-agreed target of curbing the loss of species and nature by 2010, a major study has confirmed.
Virtually all species and ecosystems show continued decline, while pressures on nature are increasing, it concludes.
Published in the journal Science, the study confirms what conservationists have known for several years.
The 2010 target was adopted in 2002, but the scientists behind this study say implementation has been "woeful".
"Our analysis shows that governments have failed to deliver on the commitments they made in 2002," said research leader Stuart Butchart, from the UN Environment Programme's World Conservation Monitoring Centre (Unep-WCMC) and BirdLife International.
"Biodiversity is still being lost as fast as ever, and we have made little headway in reducing the pressures on species, habitats and ecosystems."
Unep chief scientist Joseph Alcamo added: "Since 1970, we have reduced animal populations by 30%, the area of mangroves and seagrasses by 20% and the coverage of living corals by 40%.
"These losses are clearly unsustainable."...

2010 April 10. Giant Lizard Discovered in the Philippines is New Species. NY Times. Excerpt: MANILA, Philippines (AP) -- Researchers have concluded that a giant, golden-spotted monitor lizard discovered in the forested mountains of the Philippines six years ago is a new species, according to a study released Wednesday.
The 6.5-foot (2-meter) -long lizard was first spotted in 2004 in the Sierra Madre mountains on the main island of Luzon when local researchers saw local Agta tribesmen carrying one of the dead reptiles.
But it took until last year to determine it was a new species. After capturing an adult, researchers from the University of Kansas and the National Museum of the Philippines obtained DNA samples that helped confirm the lizard was new to science.
...''I knew as soon as I saw the animal that it was something special,'' Luke Welton, a graduate student at the University of Kansas and one of the co-authors of the study, said in a statement.
It is not that unusual to find a new species of tiny fish, frog or insect these days. But Welton and his colleagues said it was a ''rare occurrence'' to discover such a large vertebrate, particularly on an island hit by deforestation and nearby development. They compared their find to the 1993 discovery of the forest-dwelling Saola ox in Vietnam and a new monkey species discovered in the highlands of Tanzania in 2006....

2010 March 12. Climate Change Threatens Migratory Birds, Report Says. By John M. Broder, NY Times. Excerpt: WASHINGTON — Changes in the global climate are imposing additional stress on hundreds of species of migratory birds in the United States that are already threatened by other environmental factors, according to a new Interior Department report.
The latest version of the department’s annual State of the Birds report shows that nearly a third of the nation’s 800 bird species are endangered, threatened or suffering from population decline.
For the first time, the report adds climate change to other factors threatening bird populations, including destruction of habitat, hunting, pesticides, invasive species and loss of wetlands....

2010 Feb 18. World's most endangered primates revealed. IUCN. Excerpt: Mankind’s closest living relatives – the world’s apes, monkeys, lemurs and other primates – are on the brink of extinction and in need of urgent conservation measures according to Primates in Peril: The World’s 25 Most Endangered Primates, 2008–2010.
The report, compiled by 85 experts from across the world, reveals that nearly half of all primate species are now in danger of becoming extinct from destruction of tropical forests, illegal wildlife trade and commercial bushmeat hunting. The list includes five primate species from Madagascar, six from Africa, 11 from Asia, and three from Central and South America, all of which are the most in need of urgent conservation action.
Conservationists want to highlight the plight of species such as the golden headed langur (Trachypithecus p. poliocephalus), which is found only on the island of Cat Ba in the Gulf of Tonkin, north-eastern Vietnam, where just 60 to 70 individuals remain. Similarly, there are thought to be less than 100 individual northern sportive lemurs (Lepilemur septentrionalis) left in Madagascar, and around 110 eastern black crested gibbons (Nomascus nasutus) in northeastern Vietnam.
...Almost half (48 percent) of the world’s 634 primate species are classified as threatened with extinction on the IUCN Red List of Threatened Species™. The main threats are habitat destruction, particularly from the burning and clearing of tropical forests (which results in the release of around 16 percent of the global greenhouse gases causing climate change), the hunting of primates for food, and the illegal wildlife trade....

2009 July 25. New Creatures in an Age of Extinctions. By Natalie Angier, The NY Times. Excerpt: ...Since the last summary of the world’s mammals was published in 2005, tallying the roughly 5,400 mammalian species then known, Dr. Helgen, curator of mammals at Smithsonian Institution’s National Museum of Natural History, said an astounding 400 or so new species have been added to the list. “Most people don’t realize this,” he said, “but we are smack-dab in the middle of the age of discovery for mammals.”
Yet as he and other biologists are all too aware, we are also smack-dab in the middle of a great species smack down, an age of mass extinctions for which we humans are largely to blame. Estimates of annual species loss vary widely and are merely crude guesstimates anyway, but most researchers agree that, as a result of habitat destruction, climate volatility, pesticide runoff, ocean dumping, jet-setting invasive species and other “anthropogenic” effects on the environment, the extinction rate is many times above nature’s chronic winnowing. “Our best guess is that it’s hugely above baseline, a hundred times above baseline,” said John Robinson, an executive vice president at the Wildlife Conservation Society. “The problem is, we’ve only described an estimated 15 percent of all species on Earth, so most of what’s going extinct are things we didn’t even know existed.”
In sum, we have a provocatively twinned set of rising figures: on the one hand, the known knowns, that is, the number of new species that researchers are divulging by the day; and on the other, the unknown unknowns, the creatures that are fast disappearing without benefit of a Linnaean tag....

2009 July 2. World 'still losing biodiversity'. BBC News. Excerpt: An unacceptable number of species are still being lost forever despite world leaders pledging action to reverse the trend, a report has warned. The International Union for the Conservation of Nature (IUCN) says the commitment to reduce biodiversity loss by 2010 will not be met. It warns that a third of amphibians, a quarter of mammals and one-in-eight birds are threatened with extinction. The analysis is based on the 44,838 species on the IUCN Red List.
"The report makes for depressing reading," said co-editor Craig Hilton Taylor, manager of the IUCN's Red List Unit.
"It tells us that the extinction crisis is as bad, or even worse than we believed.
...The main policy mechanism to tackle the loss is the Convention for Biological Diversity (CBD), which came into force in 1993... Currently, 168 nations are signatories to the convention, which set the target "to achieve by 2010 a significant reduction of the current rate of biodiversity loss at the global, regional and national level".
Jean-Christophe Vie, deputy head of the IUCN's Species Programme, warned that the scale of "wildlife crisis" was far worse than the current global economic crisis.
"It is time to recognise that nature is the largest company on Earth working for the benefit of 100% of humankind," he said....
The assessment lists 869 species as Extinct or Extinct in the Wild. Overall, the report categorises at least 16,928 species as being threatened with extinction....

2009 June 17. Dingoes 'could help rare species'. By Richard Black, BBC News. Excerpt: Re-introducing dingoes across tracts of Australia could have benefits for wildlife and possibly cattle farmers.
Researchers found that dingoes suppress populations of kangaroos and red foxes, which are big consumers of vegetation and small mammals respectively.
Writing in the Royal Society's journal Proceedings B, they say the benefits of dingoes outweigh concerns over their presence as an "alien predator".
The wild dogs were brought to Australia about 5,000 years ago. Their appetite for sheep means they have been expelled from large swathes of the country, notably the productive farmlands of New South Wales and Victoria, where a "dingo fence" more than 5,000km long has been erected to keep the predators out.
But this may have contributed to the demise of some native animals and the endangerment of many more.
"There is a lot of pressure to get rid of dingoes, and they can do damage," said Michael Letnic from the University of Sydney.
..."But dingoes suppress fox and kangaroo numbers, and when you don't have dingoes in the system, kangaroos basically eat all the herbiage and foxes take all of the prey."...

2009 February 17. Debate Rages Over Elk Feeding. By Kirk Johnson, The NY Times. Excerpt: JACKSON, Wyo. — When the mighty elk herds of the West were facing the possibility of extinction from overhunting, settlement and neglect a century ago, people here stepped forward and began what has turned out to be a profound biological experiment.
They offered food to the straggling survivors.
The Jackson herd, now tens of thousands of animals strong, became the foundation for a resurgent elk population. After the federal government stepped in to run the feeding system in 1912, a self-reinforcing loop of tourism, hunting, ranching and politics emerged. Having lots of elk in one place where humans would feed them, year in and year out, gradually became a goal in itself, shrouded with complex motives and enshrined by time.
...Now a new and tightening circle of challenges is closing in on the elk and the human system that has sustained them, forcing a debate over the science, emotion and economics of protecting these magnificent animals and the landscape they inhabit. At the center is a critical question: Did human kindness backfire, setting the elk up for disaster?
A federal lawsuit filed last year by a coalition of environmental groups charges that feeding the elk violates the Fish and Wildlife Service’s charter to manage refuges for healthy populations and biological integrity. Feeding programs, the suit argues, endanger the elk and create monocultures that degrade the landscape for other creatures, like birds, which can no longer nest on feeding grounds stripped of willows by the ravenous herd....
