Arctic ground squirrels survive the long winter by hibernating for seven or eight months in dens, or hibernaculae, about 100 centimetres below ground surface. Arctic Ground Squirrels. By virtue of their profound ability to suppress metabolism and core temperature, with body temperatures dropping below 0°C, AGS are … The Arctic ground squirrel has developed highly specialized adaptations to extreme environments, and it has a lot to teach us about circadian rhythms and … One of the largest species of ground squirrel (2), the Arctic ground squirrel (Spermophilus parryii) is, as its common name suggests, ground-dwelling (4). Ground squirrels have a streamlined shape that helps them move swiftly through their burrows.
