Frogs already knew it wasn’t easy being green, but the going just got a lot tougher for the 1,012 additional species of amphibians who have now been newly identified as at risk of extinction in a Yale-led study published in the Journal of Current Biology.  “Amphibians are highly threatened and are declining worldwide at an unprecedented rate,” said lead author Pamela González-del-Pliego, postdoctoral ecologist at Yale. “Unfortunately, it seems that the percentage of threatened amphibians is much higher than we previously knew.”
