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.
Cold air damming typically happens in the mid-latitudes as this region lies within the Westerlies, an area where frontal intrusions are common.When the Arctic oscillation is negative and pressures are higher over the poles, the flow is more meridional, blowing from the direction of the pole towards the equator, which brings cold air into the mid-latitudes.

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.
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 first arctic outbreak of the season is allowing temperatures to plunge across the eastern half of the country, creating "dangerously cold" wind chills of 15-30 degrees below zero in the ...
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.
Thermographic image: a cold-blooded snake is shown eating a warm-blooded mouse. Warm-blooded is an informal term referring to animal species whose bodies maintain a temperature higher than that of their environment. In particular, homeothermic species (including birds and mammals) maintain a stable body temperature by regulating metabolic ...
It is recognized as a subspecies of Canis lupus in the taxonomic authority Mammal Species of the World (2005). [4] It was formally discovered, classified, and named after Peter Bernard, sailing master of the gas schooner Mary Sachs of the Canadian Arctic Expedition and collected four other specimens of Canis Lupus Bernardi, and Joseph F. Bernard, his nephew, who made voyages into the Arctic as ...
