  • Black bears hibernate for 5 to 7 months a year and, during this time, do not eat, drink, urinate, or defecate. [...] Key Result Heart rates were reduced from 55 to as few as 9 beats per minute, with profound sinus arrhythmia. After returning to normal body temperature and emerging from dens, bears maintained a reduced metabolic rate for up to 3 weeks. The pronounced reduction and delayed recovery of metabolic rate in hibernating bears suggest that the majority of metabolic suppression during hibernation is…Expand Abstract
