Mountain yellow legged frogs aided in recovery by translocating disease resistant animals congrats to Knapp et al! www.anthropocenemagazine.org/2024/12/this...
This could be the posterfrog for what ails the world’s amphibians. But it’s staging a comeback.
Some individuals of the Sierra Nevada yellow-legged frog survived the fungal plague wiping out species around the world. Now, scientists have shown they can recolonize habitat.

Axolotls are one of the most widely bred captive amphibians yet they are critically endangered because Mexico City was built on top of their home -lake Xochimilco. These folks have been reintroducing them 👍🐸👏 wapo.st/4d2TZgi gift article
Endangered axolotls bred in captivity can survive in wild, study finds
The findings could aid conservation efforts for the beloved species, which is found in only one Mexico City lake.
