The only time at which the wolf migrates is during the wintertime when there is complete darkness for 24 hours. This makes Arctic wolf movement hard to research. About 2,250 km (1,400 mi) south of the High Arctic, a wolf movement study took place in the wintertime in complete darkness, when the temperature was as low as −53 °C (−63 °F).
A wolf carrying a caribou hindquarter, Denali National Park, Alaska. Like all land mammals that are pack hunters, the wolf feeds predominantly on ungulates that can be divided into large size 240–650 kg (530–1,430 lb) and medium size 23–130 kg (51–287 lb), and have a body mass similar to that of the combined mass of the pack members.
For North America, he proposed that there were only five subspecies of the wolf. These include a large-toothed Arctic wolf named C. l. arctos, a large wolf from Alaska and western Canada named C. l. occidentalis, a small wolf from southeastern Canada named C. l. lycaon, a small wolf from the southwestern U.S. named C. l. baileyi and a moderate ...

The muskox (Ovibos moschatus) [a] [b] is a hoofed mammal of the family Bovidae. [8] Native to the Arctic, it is noted for its thick coat and for the strong odor emitted by males during the seasonal rut, from which its name derives. This musky odor has the effect of attracting females during mating season.
At the end of the most recent glacial retreat during the past 30,000 years, warming melted the glacial barriers across northern Canada allowing arctic mammals to extend their range into mid-latitude North America, including elk, caribou, bison, and the grey wolf. [54]
Wolf populations in Romania remained largely substantial, with an average of 2,800 wolves being killed annually out of a population of 4,600 from 1955 to 1965. An all-time low was reached in 1967, when the population was reduced to 1,550 animals.
