The Kodiak bear (Ursus arctos middendorffi), also known as the Kodiak brown bear and sometimes the Alaskan brown bear, inhabits the islands of the Kodiak Archipelago in southwest Alaska. [3] It is one of the largest recognized subspecies or population of the brown bear , and one of the two largest bears alive today, the other being the polar bear .
[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 ]
The Alaskan Peninsula provides an important habitat for fish, mammals, reptiles, and birds. At the top of the food chain are the bears. Alaska contains about 70% of the total North American brown bear population and the majority of the grizzly bears, as well as black bears and Kodiak bears.
Considering pinnipeds [73] and polar bears [74] [44] [75] to be marine mammals, the Kodiak bear is the largest [76] [77] of the living land-based mammalian predators. The largest subspecies are the Kodiak bear (U. a. middendorffi) and the questionably-distinct peninsular giant bear or coastal brown bear (U. a. gyas).
The brown bear (Ursus arctos) is a large bear native to Eurasia and North America. Of the carnivorans, it is rivaled in size only by its closest relative, the polar bear, which is much less variable in size and slightly bigger on average. The brown bear is a sexually dimorphic species, as adult males are larger and more compactly built than ...
“Kodiak bears are the largest bears in the world. A large male can stand over 10 (feet) tall when on his hind legs, and 5 (feet) when on all four legs. They weigh up to 1,500 pounds.”
How to find your maximum heart rate: 220 - your age = MHR. For example: if you’re 35 years old, your MHR is 185 BPM (220-35), and 60 to 70 percent of that is 111 to 130 BPM.
During their time in hibernation, an American black bear's heart rate drops from 40 to 50 beats per minute to 8 beats per minute, and the metabolic rate can drop to a quarter of the bear's (nonhibernating) basal metabolic rate. These reductions in metabolic rate and heart rate do not appear to decrease the bear's ability to heal injuries during ...
