"Climate change is implicated as the cause of geographic shifts observed among birds, small mammals and plants, but this new work shows that, particularly for mountain species like the alpine chipmunk, such shifts can result in increasingly fragmented and genetically impoverished populations," says the study’s lead author, Emily Rubidge, who conducted the research while a Ph.D. student at UC Berkeley's Department of Environmental Science, Policy and Management. Low genetic diversity can render a species more vulnerable to the effects of inbreeding, disease and other problems that threaten species survival. "Under continued warming, the alpine chipmunk could be on the trajectory toward becoming
