The higher stoat numbers reduce the rodent population and the stoats then prey on birds. [6] For instance, the wild population of the endangered takahē dropped by a third between 2006 and 2007, after a stoat plague triggered by the 2005–2006 mast wiped out more than half the takahē in areas where stoat numbers were not limited by trapping. [7]
The stoat thrived during the Ice Age, as its small size and long body allowed it to easily operate beneath snow, as well as hunt in burrows. The stoat and the long-tailed weasel remained separated until 500,000 years ago, when falling sea levels exposed the Bering land bridge. [20] Fossilised stoat remains have been recovered from Denisova Cave ...
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
The Māori also brought two species of land mammals, Polynesian rats (Rattus exulans) and kurī, a breed of domestic dog (Canis lupus familiaris). [3] [16] In pre-human times, bats were the only land mammals found in New Zealand. [17] Polynesian rats definitely contributed to extinctions, [3] and kurī might have contributed as well.
The New Zealand long-tailed bat is considered to be critically endangered (CR). The sei, fin and blue whales are all endangered (EN), as is the Hector's dolphin which is found only in New Zealand waters. The Department of Conservation ranks priorities for conservation with the New Zealand Threat Classification System.
Eight of the extinct bird species were found in Hawaii, including the Po`ouli, which was last seen in 2004. The Po`ouli is the most recently seen species of all 21 animals on the list.
As of February 2021, the International Union for Conservation of Nature (IUCN) lists 299 extinct species, 149 possibly extinct species, 14 extinct in the wild species, two possibly extinct in the wild species, eight extinct subspecies, one possibly extinct subspecies, and five extinct in the wild subspecies of mollusc. [1]
The extinct huia was a member of the endemic bird family Callaeidae (New Zealand wattlebirds). Birds comprise the most important part of New Zealand's vertebrate fauna. It is uncertain if many birds in New Zealand are descended from Gondwanan stock, as DNA evidence suggests that even the ratites (the kiwis and the moas ) arrived after the split ...
