Arctic fox

Vulpes lagopus

The arctic fox , also known as the white fox, polar fox, or snow fox, is a small fox native to the Arctic regions of the Northern Hemisphere and is common throughout the Arctic tundra biome. It is well adapted to living in cold environments. It has a deep thick fur which is brown in summer and white in winter. It averages in size at about 85.3 cm in body length, with a generally rounded body shape to minimize the escape of body heat.

They prey on any small animals they can find, including lemmings, voles, ringed seal pups, fish, and seabirds. They will also eat carrion, berries, and seaweed. They form monogamous pairs during the breeding season and usually stay together in family groups of multiple generations in complex underground dens.

Besides the nominate subspecies, ''Vulpes lagopus lagopus'', there are four other subspecies of this fox:

The arctic fox has a circumpolar range, meaning that it is found throughout the entire Arctic, including the outer edges of Greenland, Russia, Canada, Alaska, and Svalbard, as well as in Subarctic and alpine areas, such as Iceland and mainland alpine Scandinavia. The conservation status of the species is good, except for the Scandinavian mainland population. It is acutely endangered there, despite decades of legal protection from hunting and persecution. The estimate of the adult population in all of Norway, Sweden and Finland is a mere 120 individuals.

The arctic fox is the only land mammal native to Iceland....hieroglyph snipped... It came to the isolated North Atlantic island at the end of the last ice age, walking over the frozen sea. The Arctic Fox Center in Súðavík contains an exhibition on the arctic fox and conducts studies on the influence of tourism on the population.

The abundance of the arctic fox tends to fluctuate in a cycle along with the population of lemmings and voles . The populations are especially vulnerable during the years when the prey population crashes, and uncontrolled trapping has almost eradicated two subpopulations.

The pelts of arctic foxes with a slate blue coloration—an expression of a recessive gene—were especially valuable. They were transported to various previously fox-free Aleutian Islands during the 1920s. The program was successful in terms of increasing the population of blue foxes, but their predation of Aleutian Canadian 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. Red foxes dominate where their ranges begin to overlap by killing arctic foxes and their kits. An alternate explanation of the red fox's gains involves the gray wolf: 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. In areas of northern Europe, there are programs in place that allow the hunting of red foxes in the arctic fox's previous range.

As with many other game species, the best sources of historical and large scale population data are hunting bag records and questionnaires. There are several potential sources of error in such data collections. In addition, numbers vary widely between years due to the large population fluctuations. However, the total population of the arctic fox must be in the order of several hundred thousand animals.

The world population is thus not endangered, but two arctic fox subpopulations are. One is on Medny Island , which was reduced by some 85–90%, to around 90 animals, as a result of mange caused by an ear tick introduced by dogs in the 1970s. The population is currently under treatment with antiparasitic drugs, but the result is still uncertain.

The other threatened population is the one in Fennoscandia . 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. The population has remained at a low density for more than 90 years, with additional reductions during the last decade. The total population estimate for 1997 is around 60 adults in Sweden, 11 adults in Finland and 50 in Norway. From Kola, there are indications of a similar situation, suggesting a population of around 20 adults. The Fennoscandian population thus numbers around 140 breeding adults. Even after local lemming peaks, the arctic fox population tends to collapse back to levels dangerously close to non-viability.

The arctic fox is classed as a "prohibited new organism" under New Zealand's Hazardous Substances and New Organisms Act 1996 preventing it from being imported into the country.

The arctic fox tends to be active from early September to early May. The gestation period is 52 days. Litters tend to average 5–8 kits but may be as many as 25 . Both the mother and the father help to raise their young. The females leave the family and form their own groups and the males stay with the family.

Foxes tend to form monogamous pairs in the breeding season. Litters are born in the early summer and the parents raise the young in a large den. Dens can be complex underground networks, housing many generations of foxes. Young from a previous year's litter may stay with the parents to help rear younger siblings. The kits are initially brownish; as they become older they turn white. Their coat of fur also changes color when summer arrives, but in winter it is white.

The arctic fox will generally eat any small animal it can find: lemmings, voles, hares, owls, eggs, and carrion, etc. Lemmings are the most common prey. A family of foxes can eat dozens of lemmings each day. During April and May, the arctic fox also preys on ringed seal pups when the young animals are confined to a snow den and are relatively helpless. Fish beneath the ice are also part of its diet. They also consume berries and seaweed and may thus be considered omnivores. It is a significant bird egg predator, excepting those of the largest tundra bird species. If there is an overabundance of food, the arctic fox will bury the surplus as a reserve. When its normal prey is scarce, the arctic fox scavenges the leftovers and even feces of larger predators, such as the polar bear, even though the bear's prey includes the arctic fox itself.
