Kwasi studies two species in particular that make their homes in the Sierra Nevada Mountains of California: the alpine chipmunk and the lodgepole chipmunk. With the climate warming and high ...

Global warming has driven Yosemite's alpine chipmunks to higher ground, prompting a startling decline in the species' genetic diversity, according to a new study. The genetic erosion occurred in ...

Backpacking scientists from UC Berkeley have gathered compelling evidence that the warming High Sierra climate is pushing still another animal species to seek cooler habitats amid the higher ...

The alpine chipmunk only lives in California, and its habitat is shrinking. The alpine chipmunk, found in Yosemite’s high country, has moved upslope as temperatures have warmed over the last ...

Jim Patton, a retired professor of zoology at the University of California at Berkeley, had his quarry: the tiny, ash-gray alpine chipmunk, a Sierra Nevada native that is one of the leading ...

Delving into the deep Museum of Vertebrate Zoology archives, the Berkeley team sampled skin from the actual alpine chipmunks Grinnell trapped in Yosemite nearly a century ago, had the samples ...

In the early 1900s, Grinnell and colleagues found alpine chipmunks at elevations of 7,800 feet. In the new survey, chipmunks stuck to a range about 1,640 feet higher upslope. To test the genetic ...

We have 13 species! And the real chipmunk ground zero is the Sierra Nevada. Driving from the Bay Area to Mono Lake you go through the territory of the Sonoma, yellow-pine, long-eared, shadow, ...

The critters are small, such as the alpine chipmunk and the yellow-bellied marmot. You might also see birds such as the gray-crowned rosy finch, which forages on ridgetops above 9,000 feet.

Discovered: What the moon's insides look like, the tiniest transistor of all time, climate change is killing alpine chipmunks, and get ready for test-tube hamburgers.

The alpine chipmunk has scurried 1,800 feet upward since Grinnell's time. The climate models are showing a relationship between the change in weather and the animal movement, the scientists report.
