ScienceShot: Marmots Thrive on Climate Change
21 July 2010 1:00 pm
Yellow-bellied marmots (Marmota flaviventris) might not be as cowardly as their name suggests. While most of the world lives in fear of climate change, these rodents embrace it. Thanks to warming temperatures in Colorado, the marmots have been getting up earlier from hibernation each year, giving them more time to feed. As a result, they grow about 10% bigger than they used to, researchers will report tomorrow in Nature. That extra weight helps the marmots survive longer, giving each group time to produce an average of 14 more courageous little yellow-bellies a year than did their predecessors.
