Arctic wolf feeding on muskox carcass in Ellesmere Island. Very little is known about the movement of the Arctic wolves, mainly due to climate. 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.
The winter fur is highly resistant to the cold. Wolves in northern climates can rest comfortably in open areas at −40 °C (−40 °F) by placing their muzzles between the rear legs and covering their faces with their tail. Wolf fur provides better insulation than dog fur and does not collect ice when warm breath is condensed against it. [46]
Muskoxen live in herds of 12–24 in the winter and 8–20 in the summer when dominant bulls expel other males from the herd. [52] They do not hold territories, but they do mark their trails with preorbital glands. [53] Male and female muskoxen have separate age-based hierarchies, with mature oxen being dominant over juveniles. [52]
Hoarding food for the long, cold winter. Adequate food resources and energy reserves are essential for an animal’s success and survival but winter food supplies and energy reserves are critical ...
Water is an important part of human survival. Because of its cold temperature, much of the Earth's water comes from the polar regions. 90% of the world's water comes from the Antarctic ice cap although a lot of this water is not used. [11] Water environments are important for many species around the world.
Slightly smaller than gray wolves, their southern relatives, Arctic wolves typically weigh between 55 and 70 pounds as adults. They can travel long distances and hunt in packs, which aids them in ...
Overwintering is the process by which some organisms pass through or wait out the winter season, or pass through that period of the year when "winter" conditions (cold or sub-zero temperatures, ice, snow, limited food supplies) make normal activity or even survival difficult or near impossible. In some cases "winter" is characterized not ...
Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest) and tundra. [2]
