There are so few wild ocelots in the US that the cats are becoming inbred, with a bad prognosis for their ultimate survival. But researchers are perfecting ways to get new genes into the population.
It’s been 80 years since the last undisputed sighting of the striking black-and-white bird. The U.S. government believes the ivory-billed woodpecker is extinct — but many will keep searching for it.
Nearly all species of sharks and rays are captured in fishing operations. But research shows that fishing quotas and closing some areas to fishing can help rebuild threatened populations.
Feral horses trample endangered plant communities, destroy threatened species’ habitat and damage Aboriginal cultural heritage — and their numbers are increasing.
Bats roost under bridges and culverts across North America, so highway departments have to check for them before repairing bridges. A new AI tool makes those inspections faster and more accurate.
Spiny-tailed skinks, also known as meelyu, are culturally significant to the Badimia people in Western Australia. But habitat degradation and mining have put them at threat of extinction.
Less attractive endangered species don’t tend to receive the same public attention as their more beautiful counterparts: new studies show how we might help change that.
The giant sea bass fishery collapsed long ago in the US, but that didn’t mean the species was endangered. New research shows these iconic fish have been thriving south of the border.

The male anatomy of tuatara, the last representatives of an ancient lineage, is unique among reptiles. They lack a penis, which has made sperm collection a major challenge – until now.
In the past, wildlife vigilantes have illegally moved Tasmanian devils off the island — an illegal practice known as “covert rewilding”. They may well might try again.
Given the scale of the problem, five years was never enough time to turn things around. Clearly, we must reflect honestly on our successes and failures so far.
The remaining populations are threatened by a lack of genetic diversity, which makes them less likely to bounce back from new pressures such as climate change.
