While it may seem obvious that a decline in amphibians could impact its predators, showing that this is true requires having long-term data from a particular site, which is very rare and difficult to attain, says Kelly Zamudio, an ecology professor and herpetology curator at Cornell University who wasnt involved in the paper. But quality journalism comes at a price. But then, her study speciessnakesbegan to be affected.
