putting the squeeze on Salamanders

Wild salamanders that live in the Appalachian Mountains are shrinking because they must burn more energy as the local climate gets hotter and drier, according to a new study.

Researchers found that the salamanders they collected between 1980 and 2012 were 8 percent smaller than those collected in earlier decades, starting in 1957.

The findings confirm predictions that some species will shrink in response to climate change. The climate where the salamanders live has gotten warmer and drier, researchers said.

We compared the size of the museum specimens to the current animals and we were surprised to see that, in fact, many species has become smaller over just a 50- to 60-year period, said study author Karen Lips, a biologist at the University of Maryland.
