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.

Construction site of the Gemini solar project in southern Nevada. Documents obtained under the Freedom of Information Act by the conservation group Defenders of Wildlife show the bureau’s Las Vegas field office drafted several versions of a “record of decision” that would have denied the permit application for Gemini. The drafts listed several objections, including harm to desert tortoises, loss of space for off-road vehicle drivers and disturbance of the Old Spanish National Historic Trail, which runs through the project site.

Global loss of biodiversity is significantly more alarming than previously suspected – “Almost half of animals on Earth for which assessments are available are currently declining. To make matters worse, many of the animal species that are thought to be non-threatened from extinction are in fact progressively declining”

23 May 2023 (Queen’s University Belfast) – A new study led by researchers from Queen’s University Belfast has shown that the global loss of biodiversity caused by human industrialisation is significantly more alarming than previously thought. The global-scale analysis has been published in the journal Biological Reviews. The study looked at changes in the population densities […]

All of the species declared extinct in the 2010-2019 decade – “The trends that connect these 160 extinctions are true of the biodiversity crisis more generally”

By Ryan F. Mandelbaum 16 December 19 (Gizmodo) – Lonesome George, the last of the Pinta Island tortoises, died in 2012. George’s story is the perfect extinction story. It features a charismatic character with a recognizable face, an obvious villain, and the tireless efforts of naturalists. The population of the Pinta Island tortoise species was […]
