Arctic Fox


Animal You | Arctic Fox | The Arctic fox lives in a part of the cold end of the planet. The fox has occupied a small surface to volume ratio, as its generally rounded body shape, short muzzle and legs and ears short, thick. The Arctic fox has an ear so acute that accurately locate the position of prey under the snow. Foxes tend to form monogamous pairs in the breeding season. Your skin also changes color when it's summer, but in winter is white. The tail is 31 cm (12.2 inches) long in males and 30 cm (11.8 inches) long in women. Males weigh an average of 3.5 kg (7.7 lb), with a range of 3.2 to 9.4 kg (7.1 to 21 lb), while women average of 2.9 kg (6 , 4 pounds), in which a range of 1.4 to 3.2 kg (3.1 to 7.1 pounds). The arctic fox is an animal usually eats small it can find: lemmings, voles, hares, owls, eggs and carrion, etc A family of foxes can eat dozens of lemmings each day. In April and May the Arctic Fox also hunting ringed seal pups when the young animals are confined to a snow den and are relatively helpless.

If there is an oversupply of food hunted, the arctic fox will bury what the family can not eat. When its normal prey is scarce, the arctic fox and even washed the remains feces of large predators such as the polar bear, while the bear's prey includes the arctic fox itself. The conservation status of the species is good, except for the Scandinavian mainland population. Estimating the total population of Norway, Sweden and Finland, only 120 adults. The arctic fox is the only native land mammal in Iceland. The Arctic Fox Center Súðavík contains an exhibition on the arctic fox and conducts research on the impact of tourism on the population. The abundance of arctic fox species tends in a loop with the population of lemmings and voles (a cycle of 3-4 years) vary. The populations are especially vulnerable during the years when prey population crashes, and uncontrolled capture exterminated nearly two subpopulations.

The Arctic fox pelts, slate the expression of a recessive gene were particularly valuable. They were taken to various previously fox-free Aleutian Islands in 1920. The arctic fox is losing ground to the larger red fox. Red foxes dominate their ranges overlap start killing arctic foxes and kit. An alternative explanation of the benefits include the red fox, gray wolf: Historically, the number of red foxes down, but kept the wolf hunted close to extinction in much of its former range, the red fox population has grown, and is taken into African predator. In northern areas of Europe, there are programs that allow hunting of red fox in the first rank of arctic fox.

As with many other species of game are the best sources of historical documentation and game bag large populations and questionnaires. The world population is thus not endangered, but two arctic foxes are subpopulations. The other population is threatened. The total population estimate for 1997 is around 60 adults in Sweden, 11 adults in Finland and 50 in Norway. From a population of approximately 20 adult population numbers The Fennoscandian then for a total of 140 adult breeding. Even after local lemming peaks, the arctic fox population tends to collapse dangerously to lack of profitability.
