What are some adaptations of an Arctic ground squirrel? They are not territorial but males will defend a small home-range from other males. Present-day arctic ground squirrel populations range in distribution from northeast Siberia across mainland northern North America to Hudson Bay (Fig.

This extreme metabolic adaptation makes the Arctic ground squirrel the perfect object of study for Jun Yan, a scientist from Shanghai. The Arctic fox is basically an opportunistic predator which feeds small mammals – like lemmings and ground squirrels, as well as insects and eggs. Over the course of time, this species has adapted to a diet which helps them survive in the summer and winter of the Arctics. Arctic ground squirrel adaptations. This squirrel is best adapted to carry on the life processes of feeding, hibernating and evading enemies in areas where permafrost is several feet below the surface of the ground (Bee and Hall, 1956: 47).

This species maintains circadian rhythms throughout the Arctic summer, despite the almost ceaseless daylight during this period. Males groups number up to 19 individuals who are not related and are not agonistic. Present-day arctic ground squirrel populations range in distribution from northeast Siberia across mainland northern North America to Hudson Bay (Fig. Adult males live separately from females and only join to breed.
While hibernating, a ground squirrel uses 98 percent less energy than while awake. Yukon's Ice Age Ground Squirrels .

Yan has been working closely with Brian Barnes, a scientist from Institute of Arctic Biology in Fairbanks Alaska on the hibernation of Arctic ground squirrel. Arctic Ground Squirrels are social animals that live in scattered colonies to allow for greater safety from predators by having many eyes on watch.
Arctic ground squirrels are usually active between four in the afternoon and nine or ten at night. Arctic Fox Dietary Adaptations.

Cape ground squirrels live in groups of 2-3 adult females, up to 9 sub-adults of either sex and with the females’ offspring. An Arctic ground squirrel colony is made up of burrows that are dug about three feet under the ground. In particular, the arctic ground squirrel (AGS) has been shown to be highly resilient to ischemic and reperfusion injuries, demonstrating an ability to withstand metabolic stress under hibernation conditions.
