As the Arctic warms, arctic ground squirrels changing hibernation patterns
A unique long-term study, which NAU professor Loren Buck started more than two decades ago while doing his Ph.D. research in Alaska, helps us understand biological responses to climate shifts through the hibernation patterns of a cute little rodent. In the course of the 25-year study, researchers found that the female and male squirrels developed different hibernation periods over that time. The females “rise and shine” a little earlier in response to warming, which could have both positive and negative ripple effects throughout the food web in these ecosystems.
