Extinct-in-the-wild species in conservation limbo sciencemagazine currentbiology
Since 1950, nearly 100 animal and plant species vanquished from nature by hunting, pollution, deforestation, invasive lifeforms and other drivers of extinction have been put intoWhile the category"extinct in the wild" was not added to the benchmark Red List of Threatened Species until 1994, the term could have applied to all of them.
"Real opportunities to prevent extinction and return previously lost species to the wild abound and we must take them," the international team of 15 authors said.The percentage of vertebrates threatened with extinction.—looking at the"Great Dying" event 252 million years ago that annihilated 95 percent of life on Earth—showed that accelerated species loss preceded broader ecological collapse.
By the 1920s their numbers were so reduced that surviving specimens were rounded up into zoos and a breeding programme was launched in Poland. Other creatures that never made it out of intensive care include Hawaii's black-faced honey creeper, a petite bird devastated by mosquito-borne avian malaria last seen in 2004; Mexico's freshwater Catarina pupfish, unsuccessfully relocated to captivity when its native habitat dried out due to groundwater extraction; and five types of snail on the Society Islands that fell victim to an invasive carnivorous cousin.
