Squirrels Reveal Bits of Hibernome

Mammalian hibernators are unique in their ability to cope with freezing temperatures. Some mammals can lower their body temperatures to as low as –2.9°C for several weeks. In the golden-mantle ground squirrel, Spermophilus lateralis, this period of low body temperature, called torpor, is interrupted by arousals during which body temperature rises as much as 30°C in a matter of hours. Squirrels ...

Contrasting stress response of male arctic ground squirrels and red squirrels.

A hormonal-challenge protocol was used to compare the stress response of males of Arctic ground squirrels and red squirrels during the breeding season (May).
