By Alec Luhn 24 December 2023 (Scientific American) – It was a cloudy July afternoon in Alaska’s Kobuk Valley National Park, part of the biggest stretch of protected wilderness in the U.S. We were 95 kilometers (60 miles) from the nearest village and 400 kilometers from the road system. Nature doesn’t get any more unspoiled. […]

Geographical pattern of the primary drivers of deteriorating status among amphibians. a,b, The primary drivers of deteriorating status among amphibians during 1980–2004 (482 species; a) and 2004–2022 (306 species; b). Cell colour was determined by the primary driver impacting the most species. Where two primary drivers equally contribute to a cell, an intermediate colour is shown. The stars indicate where the primary driver is undetermined or there are numerous primary drivers. The cell area is 7,775 km2. Graphic: Luedtke, et al., 2023 / Nature

Climate change emerges as major driver of amphibian declines, new research finds – “It’s a gut punch and an awakening”

By JoAnn Adkins 4 October 2023 (FIU) – Amphibians are in trouble and in desperate need of conservation action, according to a new global assessment of the world’s amphibian population. Salamanders are experiencing the greatest decline in numbers, but frogs, toads, newts, and salamanders throughout the Neotropics — extending from South Florida and Caribbean islands […]

Number of generic extinctions per century among in different classes of vertebrates. The low number of reptiles and amphibia, which underestimate the magnitude of extinction pattern, is probably the result of the lack of information in earlier centuries, where very few species had been described. The dotted line represents the background extinction rate. Graphic: Ceballos and Ehrlich, 2023 / PNAS

Study finds human-driven mass extinction is eliminating entire branches of the tree of life – “We’re losing our only known living companions in the entire universe”

By Sean Cummings 18 September 2023 (Stanford News) – The passenger pigeon. The Tasmanian tiger. The Baiji, or Yangtze River dolphin. These rank among the best-known recent victims of what many scientists have declared the sixth mass extinction, as human actions are wiping out vertebrate animal species hundreds of times faster than they would otherwise […]

Forests are no longer our climate friends – “As extreme as this year’s wildfire emissions have been, they are just the latest escalation in a multi-decade flood of CO₂ pouring out of Canada’s ‘managed’ forests and forestry”

By David Wallace-Wells 6 September 2023 (The New York Times) – Canadian wildfires have this year burned a land area larger than 104 of the world’s 195 countries. The carbon dioxide released by them so far is estimated to be nearly 1.5 billion tons — more than twice as much as Canada releases through transportation, […]
