State wildlife officials estimate the state's black bear population has remained stable for the past 10 years at 50,000 to 81,000 to animals. Bears can hibernate under decks, in crawl spaces
Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It is most commonly used to pass through winter months – called overwintering.
While black bears in colder, northern climates can hibernate for six months or longer, it is generally for shorter periods in North Carolina. But they do hibernate even along the N.C. coast ...
Many of the physiological changes an American black bear exhibits during hibernation are retained slightly post-hibernation. Upon exiting hibernation, bears retain a reduced heart rate and basal metabolic rate. The metabolic rate of a hibernating bear will remain at a reduced level for up to 21 days after hibernation. [92]
Most of the energy spent during hibernation is spent in arousals (70-80%), but their function remains unresolved. Shallow hibernation patterns without arousals have been described in large mammals (like the black bear, [2]) or under special environmental circumstances. [3]
"Upon emerging from hibernation and leaving their winter dens, bears are ready to find food, and that can sometimes put them a little too close to people," Adam Hammond, state ...
Other organisms, such as a black bear, enter torpor and switch to multi-day cycles rather than rely on a circadian rhythm. However, it is seen that both captive and wild bears express similar circadian rhythms when entering torpor. Bears entering torpor in a simulated den with no light expressed normal but low functioning rhythms.
As bears wake from their extended slumber, they’re following their hunger. Hungry bears are coming out of hibernation, Yellowstone rangers say. How to stay safe
