“After nearly disappearing for good, Sierra Nevada yellow-legged frogs are once again hopping happily around California’s alpine lakes.

Scientists are celebrating the comeback of the amphibians (Rana sierrae) in Yosemite National Park. Though they’re still endangered, Sierra Nevada yellow-legged frogs have made a ‘remarkably successful’ recovery from the deadly amphibian chytrid fungus, researchers report this month in the journal Nature Communications.

‘The lakes are alive again, completely transformed,’ says study co-author Roland Knapp, a biologist at the University of California, Santa Barbara.”
