UCSB Biologist Details Recovery of Frog Species


New research from UC Santa Barbara biologist Roland Knapp and colleagues shows that after decades of decline — and despite continued exposure to stressors including non-native fish, disease and pesticides — the Sierra Nevada yellow-legged frog’s abundance across Yosemite has increased seven-fold, and at an annual rate of 11 percent, over the 20-year study period.
Those increases, occurring over a large landscape and across hundreds of populations, Knapp said, provide a rare example of amphibian recovery at an ecologically relevant scale. The findings appear in the early online edition of the Proceedings of the National Academy of Sciences.
