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.
There are various bird species that have been spotted in the Arctic. Eight species of birds reside on the polar tundra year round while 150 breed in the Arctic. [16] The birds that do breed go to the Arctic between May and July. One of the known birds is the snowy owl, which has enough fat on it to be able to survive in the cold temperatures.
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 ...
These factors result in a negligible input of solar energy to the Arctic in winter; the only things keeping the Arctic from continuously cooling all winter are the transport of warmer air and ocean water into the Arctic from the south and the transfer of heat from the subsurface land and ocean (both of which gain heat in summer and release it ...
Global warming is a threat to all the Earth's ecosystems, but it is a more immediate threat to those found in cold climates. The communities of species found at these latitudes are adapted to the cold, so any significant warming can upset the balance. For instance, insects struggle to survive the cold winters typical of the boreal forest.
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 ...
The adversity of soil and climatic conditions proves to low production levels, as well as little biomass accumulation due to slow rates of nutrient release in cold and wet soils, specifically as a result of limited nitrogen and phosphorus (Nadelhoffer et al. 1996) Additionally, there are low temperatures and strong winds in the tundra causing most vegetation to be dominated by woody plants ...
