When frogs die off, snake diversity plummets
"This study highlights the invisibility of other changes that are occurring as a result of losing amphibians," said Karen Lips, a professor of biology at UMD and a co-author of the study.
Many snakes rely on frogs and frog eggs as part of their diet, so the researchers expected a decline in frogs to impact snake populations. But the slithery reptiles are notoriously cryptic and difficult to study in the wild. How snakes fare following a chytrid epidemic was mostly a matter of conjecture before this study.
Lips and her colleagues compared seven years of survey data collected in a national park near El Copé, Panama, before the 2004 chytrid outbreak caused mass amphibian die-off, with six years of survey data collected after the die-off.标签：
