Litters may contain as many as 25 (the largest litter size in the order Carnivora). It inhabits some of the harshest conditions on earth, where temperatures can fall as low as -58˚F (-14˚C). The tundra is a cold barren wasteland that includes snow, rocks and very little variety in vegetation. On the coast of Iceland and other islands, their diet consists predominantly of birds. Arctic foxes prefer large, maze-like dens for predator evasion and a quick escape especially when red foxes are in the area. Occasionally, other family members may assist in raising their young. The type specimen was recovered from Lapland, Sweden.

An Arctic fox’s fur changes colors with the seasons of the year. [16][31] Arctic foxes maintain the temperature in their paws independently from the core temperature. The Arctic Fox has the best insulate property off any mammal and it is also one of the smallest living mammals to live in the arctic region. However, the population on the Aleutian Islands is currently being eradicated in conservation efforts to preserve the local bird population. Did you know? Surviving in such low temperatures requires bodily adaptations both inside and out. Arctic foxes survive harsh winters and food scarcity by either hoarding food or storing body fat. The program was successful in terms of increasing the population of blue foxes, but their predation of Aleutian Canada geese conflicted with the goal of preserving that species.[47]. The Arctic Fox is circumpolar and can be found throughout the Arctic region. On the coasts of Svalbard, the frequency of complex social structures is larger than inland foxes that remain monogamous due to food availability. Average Weight: 3 to 8kg (6.5-17 lbs) Average Length: 75 to 110 cm long (2.3-3.5 feet) including a tail of around 30cm (12 inches), 20 to 30cm (9-12 inches) tall at the shoulder, females slightly smaller than males Breeding Season: Arctic foxes form monogamous pairs through a breeding season (April to May) though often several females will live … She then moved on to Ellesmere Island in northern Canada, covering a total recorded distance of 3,506 kilometres (2,179 mi) in 76 days, before her GPS tracker stopped working. This includes parts of Canada, Russia, Greenland, Iceland, Scandinavia, Svalbard, and Alaska. The Arctic fox preys on many small creatures such as lemmings, voles, ringed seal pups, fish, waterfowl, and seabirds. Even after local lemming peaks, the Arctic fox population tends to collapse back to levels dangerously close to nonviability. Natal dens are typically found in rugged terrain, which may provide more protection for the pups. [53] The population has remained at a low density for more than 90 years, with additional reductions during the last decade. The arctic foxes are located in the arctic regions of the northern hemisphere, in an extremely cold environment. They are also found In Iceland where they are the only native land mammal. They are found at elevations up to 3,000 m (9,800 ft) above sea level and have been seen on sea ice close to the North Pole. Arctic foxes live in the arctic region that include Greenland, Iceland, Alaska, Canada, Russia and other location in the northern hemisphere. The arctic foxes are located in the arctic regions of the northern hemisphere, in an extremely cold environment. The world population of Arctic foxes is thus not endangered, but two Arctic fox subpopulations are. Located The Arctic Fox is circumpolar and can be found throughout the Arctic region. Arctic foxes are well adapted to the rocky, barren tundra. These dens may be in existence for many decades and are used by many generations of foxes. From Kola, there are indications of a similar situation, suggesting a population of around 20 adults. The blue morph is often a dark blue, brown, or grey color year-round. [1] It mostly inhabits tundra and pack ice, but is also present in Canadian boreal forests (northeastern Alberta, northern Saskatchewan, northern Manitoba, Northern Ontario, Northern Quebec, and Newfoundland and Labrador)[40] and the Kenai Peninsula in Alaska. As with many other game species, the best sources of historical and large-scale population data are hunting bag records and questionnaires. Arctic Foxes are Known by Several Names Arctic fox facts tell us that this animal has a high population. [17], Arctic foxes tend to select dens that are easily accessible with many entrances, and that are clear from snow and ice making it easier to burrow in. Their fur is thick and deep, even on their feet, which protects their small, … It is the only mammal to inhabit Iceland. Although it has previously been assigned to its own monotypic genus Alopex, recent genetic evidence now places it in the genus Vulpes along with the majority of other foxes.

The Arctic fox inhabits the Arctic Tundra including Alaska, Canada, Greenland, Russia, Norway, Scandinavia and Iceland; In Iceland, the Arctic fox is the only native land mammal. I.

In North America, the arctic fox is found from western Alaska east through northern Canada and in Greenland. In the summer, the thermal conductance of the Arctic foxes body is 114% higher than the winter, but their body core temperature is constant year-round. The Arctic Fox is as remarkable as it is cute. Arctic fox usually eat small animals they find like voles, fish, birds and seal pups. Residency is common in the Arctic fox population so that they can maintain their territories. [49] An alternative explanation of the red fox's gains involves the gray wolf. Globally, the Pliocene was about 2–3 °C warmer than today, and the Arctic during the summer in the mid-Pliocene was 8 °C warmer. They reside in underground complex structured dens. It was commonly believed that the Arctic fox had a lower critical temperature below −40 °C. Fat is deposited subcutaneously and viscerally in Arctic foxes. Greenland, Alaska, Canada, Svalbard and Russia and also parts of Icel… Shelter quality is more important to the Arctic fox than the proximity of spring prey to a den. Berries, carrion and seaweed are also eaten by them. The Arctic Fox Center in Súðavík contains an exhibition on the Arctic fox and conducts studies on the influence of tourism on the population. It is mostly found on tundra and pack ice, but it also lives in boreal forests in the Kenai Peninsula in Alaska and in Canada. [20] When food is overabundant, the Arctic fox buries (caches) the surplus as a reserve. [48] Red foxes dominate where their ranges begin to overlap by killing Arctic foxes and their kits. It also shows that arctic foxes do well in captivity. In the wild, most individuals do not live past their first year but some exceptional ones survive up to 11 years. [44], In July 2019, the Norwegian Polar Institute reported the story of a yearling female which was fitted with a GPS tracking device and then released by their researchers on the east coast of Spitsbergen in the Svalbard group of islands. The Arctic fox inhabits the Arctic Tundra including Alaska, Canada, Greenland, Russia, Norway, Scandinavia and Iceland; In Iceland, the Arctic fox is the only native land mammal. At the beginning of winter, the foxes have approximately 14740 kJ of energy storage from fat alone. ), The Secret Science of Solving Crossword Puzzles, Racist Phrases to Remove From Your Mental Lexicon. The abundance of the Arctic fox tends to fluctuate in a cycle along with the population of lemmings and voles (a 3- to 4-year cycle). [54] The total population estimate for 1997 is around 60 adults in Sweden, 11 adults in Finland, and 50 in Norway. [20] The populations are especially vulnerable during the years when the prey population crashes, and uncontrolled trapping has almost eradicated two subpopulations. The species possess several adaptations that help them adapt to the cold seasons. They also consume berries and seaweed, so they may be considered omnivores. Temperatures there have risen by one degree Celsius over the last hundred years, pushing the treeline deeper into the fox’s territory. Arctic foxes live in Northern North America and Greenland, throughout much of Canada and Alaska. [26], The Arctic fox also has a keen sense of smell.
