New study: frogs in Yosemite are recovering

A paper by Roland and colleagues was published today in the Proceedings of the National Academy of Sciences, USA. The accompanying UCSB story is available here. The study shows that despite the ongoing presence of introduced fish and the amphibian chytrid fungus, Sierra Nevada yellow-legged frogs are recovering across Yosemite National Park. This recovery is occurring because some lakes have been restored to their original fishless condition, and frogs are developing increased resistance to fungal infection. These results suggest that some amphibians may be more resilient than is often assumed, and with appropriate management, declines of such species may be reversible. That is great news!
