Climate Change Effects On Imperiled Sierra Frog Examined http://apocadocs.com/s.pl?1230664437
Climate change can have significant impacts on high-elevation lakes and imperiled Sierra Nevada Yellow-legged frogs that depend upon them, according to U.S. Forest Service and University of California, Berkeley, scientists. Their findings show how a combination of the shallow lakes drying up in summer and predation by introduced trout in larger lakes severely limits the amphibian's breeding habitat, and can cause its extinction... Sierra Nevada Yellow-legged frogs need two to four years of permanent water to complete their development so repeated tadpole mortality from lakes drying up in summer leads to population decline. The scientists found the effect to be a distinct mortality mechanism that could become more important in a warmer, drier climate.
