American Pikas show resiliency in the face of global warming — ScienceDaily

The American pika is a charismatic, diminutive relative of rabbits that some researchers say is at high risk of extinction due to climate change. Pikas typically live in cool habitats, often in mountains, under rocks and boulders. Because pikas are sensitive to high temperatures, some researchers predict that, as the Earth’s temperature rises, pikas will have to move ever higher elevations until they eventually run out of habitat and die out. Some scientists have claimed this cute little herbivore is the proverbial canary in the coal mine for climate change.

A new extensive review by Arizona State University emeritus professor Andrew Smith, published in the October issue of the Journal of Mammalogy, finds that the American pika is far more resilient in the face of warm temperatures than previously believed. While emphasizing that climate change is a serious threat to the survival of many species on Earth, Smith believes
