A wolf's legs are long compared to their body size allowing them to travel up to 76 km (47 mi) in 12 hours. This adaptation allows wolves to locate prey within hours, but it can take days to find prey that can be killed without great risk. Moose and deer live singly in the summer. Caribou live in herds of thousands which presents dangers for ...
Eastern moose are the third largest subspecies of moose only behind the western moose and the Alaska moose. Males stand on average 1.7–2.0 m (5.6–6.6 ft) at the shoulder and weigh up to 634 kg (1,398 lb). Females stand on average 1.7 m (5.6 ft) at the shoulder and weigh on average 270–360 kg (600–790 lb).
Alaska moose are sexually dimorphic with males being 40% heavier than females. [5] Male Alaska moose can stand over 2.1 m (6.9 ft) at the shoulder, and weigh over 635 kg (1,400 lb). When Alaska moose are born, they weigh on average about 28 pounds, but by five months old they can weigh up to 280 pounds. [4]
The Western moose [2] (Alces alces andersoni) is a subspecies of moose that inhabits boreal forests and mixed deciduous forests in the Canadian Arctic, western Canadian provinces and a few western sections of the northern United States. It is the second largest North American subspecies of moose, second to the Alaskan moose.
Subsequent protection from hunting and wolf control programs may have contributed to increased numbers but suppression of forest fires probably was the most important factor, since moose here depend on mature fir forests for winter survival. Surveys in the late 1980s suggested a total park population of fewer than 1000 moose.
The Alaskan subspecies of moose (Alces alces gigas) is the largest in the world; adult males weigh 1,200 to 1,600 pounds (542–725 kg), and adult females weigh 800 to 1,300 pounds (364–591 kg) [17] Alaska's substantial moose population is controlled by predators such as bears and wolves, which prey mainly on vulnerable calves, as well as by ...

Along with the bison and the pronghorn, [18] the muskox was one of a few species of Pleistocene megafauna in North America to survive the Pleistocene/Holocene extinction event and live to the present day. [19] The muskox is thought to have been able to survive the last glacial period by finding ice-free areas away from prehistoric peoples. [17]
