Photo 15 Mar 136 notes Tiny pika petering out with waning snow and rain

Researcher Erik Beever has watched the effects of climate change play out in front of his eyes. The U.S. Geological Survey research biologist from Bozeman, Mont., studies American pikas, which are disappearing from the Great Basin that stretches from Idaho to California and where Beever and other researchers found them just a decade ago.
A new study published this week in the journal Ecology says less winter snowpack and summer rain are the major factors in the pika’s disappearance, even where good habitat is available.
The size of pika populations did not correlate with the extent of habitat, in either the 1990s or 2000s, according to the researchers who visited sites where pikas have been recorded in surveys going back more than a century. In other words, precipitation is the deciding factor in the health of the American pika in the Great Basin, no matter how much good habitat is available.
