Some ground squirrel species – particularly those that live at higher latitudes and in colder climates – will hibernate during the winter. The hibernation of the Arctic ground squirrel is therefore not only fascinating for zoologists, it can also teach researchers a lot about the human body and diseases. The tunnels they dig along foundations, fencing, walkways, and tree roots can compromise structural in tegrity, creating dangerous collapses and costly repairs.

Most ground squirrels get out of their nest early to hunt for food, but others don’t wait till noon before going out for food search such as the eastern gray squirrel prefer sunset to sunrise so they are said to be a lazy set of squirrels. We collected regular measures of core T(b) (every 34 min) and ambient light conditions (every 30 s) before, during, and following hibernation in free-living male arctic ground squirrels. “The Arctic ground squirrels appear to survive long phases without food, at low body temperatures, and with restricted oxygen supply and blood circulation without coming to any harm.
