The IUCN Red List is the global inventory assessing extinction risk of species, ranking them from Least Concern to Extinct based on population and threat data.
No evidence-backed relationships are recorded.
Camera-trap photos of a male jaguar show the corridor linking Guatemala and Honduras is still in use, a kind of image Panthera says comes once a decade. One animal at one site confirms presence, but it cannot show that protection kept the route open.
Reality
Australian bee researchers say only three of the country's more than 1,700 native bee species are on the national threatened species list. Their review blames thin research funding for the missing data and sets out a conservation plan built on behaviour studies and long-term monitoring.
Reality
Researchers surveying 422 bird species at 1,410 sites in Borneo and Wallacea found that densely forested areas do not necessarily hold more bird diversity. They make a sound case for also judging forests by how closely related their birds are, though their public account stops short of effect sizes.
Reality
Nottingham Trent researchers who tracked 7,200 species in 613 zoos over 30 years found rising extinction risk rarely put a species in more zoos. The authors say zoos need shared planning frameworks to weigh conservation value against space, cost and visitor appeal more consistently.

Leopardus tilcayo of the Bolivian Yungas was counted inside Leopardus tigrinus until 38 sequenced genomes separated it. The living animal itself is known from two individuals, one of them a captive male.

The endangered listing rests on a model of what happens to wild-nesting colonies if beekeepers' swarms stop arriving. Its authors put the loss at about 56% over ten years, while some English populations hold steady.

Eight years of surveys at 66 sites moved Wolffsohn's viscacha from Data Deficient to Endangered on Argentina's Red List. The listing carries no automatic legal protection.

A new compilation of Namibian and South African sightings finds 95% of blue and fin whale observations came after 2012. The counts are tiny, and that is the useful part.
