Some evidence indicates that the cave bear used only caves for hibernation and was not inclined to use other locations, such as thickets, for this purpose, in contrast to the more versatile brown bear. This specialized hibernation behavior would have caused a high winter mortality rate for cave bears that failed to find available caves.
To the south, the Interior Highlands had a very high density of Arctodus simus specimens (second only to the black bear), [33] [88] due to the high rate of preservation in the cave-rich region. Sympatry between the two species is most apparent in Missouri - Arctodus simus has been found in association with black bears at Riverbluff, Bat and Big ...
Winter is finally here, and bears are getting ready to find a den to hibernate in over the next few months. In Wyoming's Yellowstone National Park, one bear was caught prepping for his long sleep ...
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.
[110] [111] During hibernation, the bear's metabolism slows down, its body temperature decreases slightly, and its heart rate slows from a normal value of 55 to just 9 beats per minute. [112] Bears normally do not wake during their hibernation, and can go the entire period without eating, drinking, urinating, or defecating. [47]
Avid hiker Michael Glidden was exploring ice caves 60 miles south of Anchorage, Alaska, when a storm kicked in. The temperatures dropped down to 25 degrees and it started to rain. Seeking shelter ...
A fecal plug (sometimes referred to as a tappen) is a significant biological phenomenon observed in bears and other animals during hibernation.It is a dense mass of hardened feces that forms in the colon due to having remained in the intestine so long that the intestinal walls have absorbed the fluids out of it, leaving it dry and hard.
