Local extinction, also extirpation, is the termination of a species (or other taxon) in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with global extinctions .
Extinct in the Wild (EW): captive individuals survive, and/or the species has been reintroduced outside its former natural range, but the species otherwise matches the criteria for "Extinct", such that no free-living, natural population is believed to exist. "Extirpated" is a term used for localized extinctions of extant species; it always ...
The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conservation status listing and ranking system. . Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmenta
In an example of conservation-induced extinction, it likely died out when the last survivors of its host species, the Iberian lynx, were taken into captivity and de-loused. [3] The specimen is slightly larger than males of most of the remaining species within the subgenus Lorisicola. [1] The female has never been seen.
By the turn of the 21st century, the Iberian lynx was on the verge of extinction, as only 94 individuals survived in two isolated subpopulations in Andalusia in 2002. Conservation measures have been implemented since then, which included improving habitat, restocking of rabbits, translocating, reintroducing and monitoring Iberian lynxes ...
In a contrasting tale, conservation efforts have revived the Iberian lynx from the brink of extinction, with the population increasing from 62 mature individuals in 2001 to 648 in 2022 and more ...
Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.
End-Capitanian extinction event: 260 Ma: Volcanism from the Emeishan Traps, [28] resulting in global cooling and other effects Olson's Extinction: 270 Ma Unknown. [29] [30] [31] Possibly a change in climate, but evidence for this is weak. [32] This event may actually be a slow decline over 20 Ma. [33] Carboniferous: Carboniferous rainforest ...
