Jessica Blios on small mammal diversity and climate change

Small mammals—gophers, mice, beavers, and their relatives—have long lurked and scurried in the wild shadows of large beasts. But recently, the world’s little creatures pattered quietly into the biology limelight. They were coaxed out of hiding by Stanford University biologists Jessica Blois and Elizabeth Hadly and University of California, Berkeley biologist Jenny McGuire, who related a new discovery connecting the loss of small mammals to a past period of climatic warming in the May 23 online edition of Nature.
