2022-12-09. Animals Are Running Out of Places to Live. [https://www.nytimes.com/interactive/2022/12/09/climate/biodiversity-habitat-loss-climate.html] By Catrin Einhorn and Lauren Leatherby, The New York Times. Excerpt: WILDLIFE IS DISAPPEARING around the world, in the oceans and on land. The main cause on land is perhaps the most straightforward: Humans are taking over too much of the planet, erasing what was there before. Climate change and other pressures make survival harder. This week and next, nations are meeting in Montreal to negotiate a new agreement to address staggering declines in biodiversity. The future of many species hangs in the balance. Meet some of the animals most affected as humans convert more and more land: ….
2022-11-11. Booming trade in mammoth ivory may be bad news for elephants. [https://www.science.org/content/article/booming-trade-mammoth-ivory-may-be-bad-news-elephants] By Michael Price, Science Magazine. Excerpt: …At the annual meeting of the Society of Vertebrate Paleontology (SVP) here last week, Huynh argued that the growing trade in ivory from the ancient carcasses now emerging as Arctic permafrost thaws is sustaining a global market that leads to the death of living elephants. He urged paleontologists to raise their voices against the fossil ivory trade—and avoid dealing with unscrupulous collectors who might be involved in it. …Ivory from African and Asian elephants commands up to $3000 per kilogram on the black market, primarily in Southeast Asia, where it is mixed into traditional medicine and carved into status-signifying statues and other trinkets. About 55 African elephants are killed every day for their tusks. But stricter poaching laws and China’s closing of legal ivory carving facilities in 2018 have made it harder for suppliers—sometimes tied to criminal syndicates—to source elephant ivory, Huynh said. “In order to make up for decreasing supply, organized crime has turned to using mammoth ivory.”…
2022-10-12. Researchers Report a Staggering Decline in Wildlife. Here’s How to Understand It.. [https://www.nytimes.com/2022/10/12/climate/living-planet-index-wildlife-declines.html] By Catrin Einhorn, The New York Times. Excerpt: …wildlife is suffering mightily on our planet, but scientists don’t know exactly how much. A comprehensive figure is exceedingly hard to determine. Counting wild animals — on land and at sea, from gnats to whales — is no small feat. …One of the most ambitious efforts to fill this void is published every two years. …the Living Planet Index, …a collaboration between two major conservation organizations, the World Wide Fund for Nature, …WWF, and the Zoological Society of London. But the report has repeatedly resulted in inaccurate headlines when journalists misinterpreted or overstated its results. The assessment’s latest number, issued Wednesday by 89 authors from around the world, is its most alarming yet: From 1970 to 2018, monitored populations of vertebrates declined an average of 69 percent. That’s more than two-thirds in only 48 years. …this number is only about vertebrates: mammals, birds, reptiles, amphibians and fish. Absent are creatures without spines, even though they make up the vast majority of animal species…. …There’s a temptation to think that an average 69 percent decline in these populations means that’s the share of monitored wildlife that was wiped out. But that’s not true. …“The Living Planet Index is really a contemporary view on the health of the populations that underpin the functioning of nature across the planet,” said Rebecca Shaw, chief scientist at WWF and an author of the report. …Another important factor is the way monitored populations end up in the index. They don’t represent a broad, randomized sampling. Rather, they reflect the data that’s available. So there is quite likely bias in which species are tracked. …One controversy has been whether a small number of populations in drastic decline call into question the overall results. Two years ago, a study in Nature found that just 3 percent of populations were driving a drastic decline. When those were removed, the global trend switched to an increase.… See also article in The Guardian. For GSS Losing Biodiversity chapter 1.

2022-07-21. Monarch Butterflies Are Endangered, Leading Wildlife Monitor Says. [https://www.nytimes.com/2022/07/21/climate/monarch-butterflies-endangered-iucn.html] By Catrin Einhorn, The New York Times. Excerpt: North America’s monarch butterfly, whose showy looks and extraordinary migration have made it one of the continent’s most beloved insects, has been classified as endangered by the International Union for Conservation of Nature, the world’s most comprehensive scientific authority on the status of species. …The numbers of Western monarchs, which live west of the Rocky Mountains, plummeted by an estimated 99.9 percent between the 1980s and 2021. While they rebounded somewhat this year, they remain in great peril. Eastern monarchs, which make up most of the population in North America, dropped by 84 percent from 1996 to 2014. The new designation of endangered covers both populations. …Monarch caterpillars depend on milkweed, the only plants they can eat. After leaving their overwintering grounds, which for most monarchs are concentrated in just a few hectares of forest in central Mexico, females deposit eggs on milkweed plants from Texas to as far north as Canada in a multigenerational journey. …American farmers turned to crops that were genetically modified to withstand glyphosate, a herbicide that is used in the weed killer Roundup. “Glyphosate was suddenly sprayed over vast acreage of farm in the Midwest,” Ms. Walker said. “That took out a lot of the milkweed plants that the monarch caterpillars rely on.” …Monarch experts are eager to enlist the public’s help in saving the species. Their message: Plant milkweed that’s native to your region, which probably means avoiding tropical milkweed (it can do more harm than good, especially in the South). Swamp milkweed is an attractive, easy-to-grow variety native to all but the most western areas of the contiguous United States. That’s for the egg-laying and caterpillars. The butterflies need nectar, so plant native flowers that bloom when monarchs are in your area.…

Excerpt: Two decades after it disappeared in nature, the stunning blue Spix’s macaw will be reintroduced to its forest home. CURAÇÁ, BRAZIL—In 1995, conservationists and scientists embarked on a desperate attempt to save the world’s rarest bird, a blue-gray parrot called the Spix’s macaw. …By the mid-1990s only a single individual remained alive in the wild, close to this dusty, small town in northeastern Brazil. …Now, conservationists are attempting to undo that fate. On 11 June, …they plan to release eight Spix’s macaws from captivity into the wild. Twelve more are supposed to follow at the end of the year and still more in the years to come. If everything goes according to plan, these birds will be the vanguard of a new population of Spix’s macaws in their natural habitat.…
2022-06-01. How the Bramble Cay melomys became the first mammal lost to the climate crisis. By Hannah Seo, The Guardian. Excerpt: No one knows how the Bramble Cay melomyses – rodents with large, liquid eyes and reddish-brown fur, small enough to fit in the palms of your hands – ended up on Bramble Cay. The cay is speck of land about 50km (31 miles) off the coast of Papua New Guinea, at the northern end of the Great Barrier Reef. …in 2015, the Bramble Cay melomys became the first mammal to go extinct directly because of human-caused climate breakdown. …Bramble Cay is only a little larger than an average US shopping mall. The highest point is about 10 feet above sea level. …The tiny cay and its essentially trapped inhabitants were susceptible to even small changes in the surrounding ocean. Climate change and rising sea levels led to salt-water intrusions throughout the island, choking much of the flora – in the decade between 2004 and 2014, the volume of leafy plants on Bramble Cay shrank by 97%. Storm surges also winnowed down the population, sweeping animals out to sea. When biologists returned in 2002 and 2004, only about a dozen melomyses could be found….

Excerpt: About 20 percent of reptile species risk extinction, mainly because people are taking away their habitats for agriculture, urban development and logging, according to the first global reptile assessment of its kind. From inch-long geckos to the iconic king cobra, at least 1,829 species of reptiles, including lizards, snakes, turtles and crocodiles, are threatened, the study found. The research, published Wednesday in Nature, adds another dimension to a substantial body of scientific evidence that points to a human-caused biodiversity crisis similar to climate change in the vast effect it could have on life on Earth. … [https://www.nytimes.com/2022/04/27/climate/reptiles-extinction-biodiversity.html] See also Science Magazine article.

2022-01-31. Massive wolf kill disrupts long-running study of Yellowstone park packs. By Virginia Morell, Science Magazine. Excerpt: Hunters are killing gray wolves in the northern Rocky Mountains in numbers not seen since the animals were driven to near extinction in the continental United States in the 20th century. The killing of more than 500 wolves in Montana, Idaho, and Wyoming in recent months…threatens to undermine a decades-old effort to restore the predators to the landscape and disrupt a long-term Yellowstone research project that has produced influential findings on how wolves help shape ecosystems. Researchers and conservation groups are calling on government officials to rethink the hunts, which have eliminated about 16% of the wolves living in the three states. …The killings are the result of a change in legal protections for Canis lupus. For decades, the wolves were strictly protected under the federal Endangered Species Act (ESA), but more than 10 years ago successful restoration efforts prompted federal officials to ease protections and give state governments a greater say in managing the species. …several states have legalized or expanded wolf hunts. Legislators in Montana, for example, last year set a goal of shrinking the state’s wolf population to “at least 15 breeding pairs,” the minimum required by the ESA; state rules allow a person to kill up to 20 wolves each season. Idaho also aims to shrink its wolf population and has set no kill limits. Wyoming has nearly achieved its goal of maintaining just 100 wolves and 10 breeding pairs outside of Yellowstone (where hunting is barred). Biologists say the recent killings won’t cause the regional extinction of wolves, …. [https://www.science.org/content/article/massive-wolf-kill-disrupts-long-running-study-yellowstone-park-packs]
