Temperature regulation in the rhythm of winter hibernation

Abstract
The work is devoted to the study for temperature regulation of hibernation rhythms in wintersleeping species of Sciuridae family. The data on observations of hibernation course on body temperature and temperature in the nest litter of 34 individuals from four species were used. For the first time graphical dependences of body temperature on the environment temperature and the dependence of the torpor duration on body temperature in squirrels in a state of hypothermia were obtained. All species have a relatively small interval of body temperature (from +1 to –1 °С), in which the longest periods of hibernation are marked, the dependence of body temperature on the environment temperature is clearly expressed. The hibernation temperature optimum zone, in all species, is close to the soil temperature regime of their native habitats during most of the wintering. Hibernators from Sciuridae and Erinaceus families, during their hibernation, demonstrate a number of similarities in the overall organization of hibernation processes, and temperature regulation of its rhythm.
