Preparing for hibernation in ground squirrels: Adrenal androgen production in summer linked to environmental severity in winter
1. At high latitudes, evolutionary adaptations focus on those that maximize survival, with hibernation being a major one used by many smaller mammals. Typically, mammalian hibernators overwinter in sites that are approximate to 0 degrees C. However, in arctic regions, such sites do not exist, necess...

Typically, mammalian hibernators overwinter in sites that are approximate to 0 degrees C. However, in arctic regions, such sites do not exist, necessitating hibernation at sites well below 0 degrees C. Lipid, the normal fuel of most hibernators, may not provide sufficient glucose needed by certain tissues to permit survival, with muscle breakdown being required.
