Fig. 1From: Body mass is associated with hibernation length, body temperature, and heart rate in free-ranging brown bearsSample sizes for each analysis. Some brown bears had only body temperature (Tb) or heart rate (HR) logging, and not both, and some were excluded from HR or Tb, due to failure of a specific logger or from one season, due to pregnancy, or in one case, killed by another bear. Some bears from summer were not available in winter, because they were killed during the autumn bear huntBack to article page
