The Arctic fox contains advantageous genes to overcome extreme cold and starvation periods. Transcriptome sequencing has identified two genes that are under positive selection : Glycolipid transfer protein domain containing 1 GLTPD1 and V-akt murine thymoma viral oncogene homolog 2 AKT2.

The Arctic fox decreases its BMR via metabolic depression in the winter to conserve fat storage and minimize energy requirements. However, some scientists have concluded that this stat is not accurate since it was never tested using the proper equipment.

The regions that have the greatest heat loss are the nose, ears, legs, and feet, which is useful in the summer for thermal heat regulation.

Also, the Arctic fox has a beneficial mechanism in their nose for evaporative cooling like dogs, which keeps the brain cool during the summer and exercise.

One way that Arctic foxes regulate their body temperature is by utilizing a countercurrent heat exchange in the blood of their legs. They do this by increasing vasodilation and blood flow to a capillary rete in the pad surface, which is in direct contact with the snow rather than the entire foot.

They selectively vasoconstrict blood vessels in the center of the foot pad, which conserves energy and minimizes heat loss. If the core temperature drops, the pad of the foot will remain constantly above the tissue freezing point.

Vulpes lagopus is a 'true fox' belonging to the genus Vulpes of the fox tribe Vulpini , which consists of 12 extant species. 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.

Arctic fox [35] Fig. Swift fox [36]. It was originally described by Carl Linnaeus in the 10th edition of Systema Naturae in as Canis lagopus. The type specimen was recovered from Lapland , Sweden.

The generic name vulpes is Latin for "fox". Looking at the most recent phylogeny, the Arctic fox diverged from the domesticated dog Canis lupus familiaris at approximately 12 MYA.

The Arctic fox and the red fox Vulpes vulpes diverged approximately 3. Additionally, the Arctic fox diverged from its sister group, the kit fox Vulpes macrotis , at about 0.

On the Tibetan Plateau , fossils of the extinct ancestral Arctic fox Vulpes qiuzhudingi from the early Pliocene 5. It is believed that this ancient fox is the ancestor of the modern Arctic fox.

By using stable carbon and oxygen isotope analysis of fossils, researchers claim that the Tibetan Plateau experienced tundra-like conditions during the Pliocene and harbored cold-adapted mammals that later spread to North America and Eurasia during the Pleistocene Epoch 2.

Besides the nominate subspecies , the common Arctic fox, V. The Arctic fox has a circumpolar distribution and occurs in Arctic tundra habitats in northern Europe, northern Asia, and North America.

In the late 19th century, it was introduced into the Aleutian Islands southwest of Alaska. However, the population on the Aleutian Islands is currently being eradicated in conservation efforts to preserve the local bird population.

The Arctic fox is the only land mammal native to Iceland. The color of the fox's coat also determines where they are most likely to be found.

The white morph mainly lives inland and blends in with the snowy tundra, while the blue morph occupies the coasts because its dark color blends in with the cliffs and rocks.

During the winter, Commuting trips in Arctic foxes last less than 3 days and occur between 0—2.

Nomadism is found in 3. Arctic foxes in Canada that undergo nomadism and migrations voyage from the Canadian archipelago to Greenland and northwestern Canada.

The duration and distance traveled between males and females is not significantly different. Arctic foxes closer to goose colonies located at the coasts are less likely to migrate.

Meanwhile, foxes experiencing low-density lemming populations are more likely to make sea ice trips. Residency is common in the Arctic fox population so that they can maintain their territories.

Nomadic behavior becomes more common as the foxes age. In July , 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 conservation status of the species is in general good and several hundred thousand individuals are estimated to remain in total. The IUCN has assessed it as being of " least concern ".

The estimate of the adult population in all of Norway, Sweden, and Finland is fewer than individuals. 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.

The pelts of Arctic foxes with a slate-blue coloration were especially valuable. They were transported to various previously fox-free Aleutian Islands during the s.

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.

The Arctic fox is losing ground to the larger red fox. This has been attributed to climate change —the camouflage value of its lighter coat decreases with less snow cover.

Historically, it has kept red fox numbers down, but as the wolf has been hunted to near extinction in much of its former range, the red fox population has grown larger, and it has taken over the niche of top predator.

As with many other game species, the best sources of historical and large-scale population data are hunting bag records and questionnaires.

Several potential sources of error occur in such data collections. However, the total population of the Arctic fox must be in the order of several hundred thousand animals.

The world population of Arctic foxes is thus not endangered, but two Arctic fox subpopulations are. This population decreased drastically around the start of the 20th century as a result of extreme fur prices, which caused severe hunting also during population lows.

From Kola, there are indications of a similar situation, suggesting a population of around 20 adults. The Fennoscandian population thus numbers around breeding adults.

Even after local lemming peaks, the Arctic fox population tends to collapse back to levels dangerously close to nonviability.

The Arctic fox is classed as a "prohibited new organism" under New Zealand's Hazardous Substances and New Organisms Act , preventing it from being imported into the country.

Retrieved 2 July When the seasons change, the fox's coat turns as well, adopting a brown or gray appearance that provides cover among the summer tundra's rocks and plants.

These colorings help foxes to effectively hunt rodents, birds, and even fish. But in winter prey can be scarce on the ground. At such times, arctic foxes will follow the region's premier predator—a polar bear—to eat the leftover scraps from its kills.
