Dehydration increases amphibian vulnerability to climate change


Amphibians have few options to avoid the under appreciated one-two punch of climate change, according to a new study from Simon Fraser University researchers and others.

Rising summer temperatures are also resulting in higher rates of dehydration among wet-skinned amphibians as they attempt to keep themselves cool.

Researchers from SFU and the University of California-Santa Cruz predict that by the 2080s, habitats previously thought to be safe for amphibians will either be too hot or too dehydrating for them to inhabit. Even the edges of wetlands may be too hot for up to 74 percent of the summer and that sunny, dry spots will be too dehydrating for up to 95 percent of the summer. MORE
