Arctic foxes generally eat any small animal they can find, including lemmings , voles , other rodents, hares , birds , eggs , fish, and carrion.

They scavenge on carcasses left by larger predators such as wolves and polar bears , and in times of scarcity also eat their feces. In areas where they are present, lemmings are their most common prey, [17] and a family of foxes can eat dozens of lemmings each day.

In some locations in northern Canada, a high seasonal abundance of migrating birds that breed in the area may provide an important food source.

On the coast of Iceland and other islands, their diet consists predominantly of birds. 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.

They also consume berries and seaweed, so they may be considered omnivores. Arctic foxes survive harsh winters and food scarcity by either hoarding food or storing body fat.

Fat is deposited subcutaneously and viscerally in Arctic foxes. At the beginning of winter, the foxes have approximately kJ of energy storage from fat alone.

Using the lowest BMR value measured in Arctic foxes, an average sized fox 3. Arctic foxes can acquire goose eggs from greater snow geese in Canada at a rate of 2.

Scats provide evidence that they eat the eggs during the winter after caching. Researchers have also noted that some eggs stored in the summer are accessed later the following spring prior to reproduction.

Among its adaptations for survival in the cold is its dense, multilayered pelage , which provides excellent insulation. There are two genetically distinct coat color morphs: white and blue.

The blue morph is often a dark blue, brown, or grey color year-round. The fox has a low surface area to volume ratio , as evidenced by its generally compact body shape, short muzzle and legs, and short, thick ears.

Since less of its surface area is exposed to the Arctic cold, less heat escapes from its body. Overall, the Arctic foxes hearing is less sensitive than the dog and the kit fox.

The Arctic fox and the kit fox have a low upper-frequency limit compared to the domestic dog and other carnivores. The Arctic fox also has a keen sense of smell.

It is possible that they use their sense of smell to also track down polar bears. 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.

Foxes will also eat vegetables when they are available. Like a cat's, this fox's thick tail aids its balance. On September 1 of Finland signed a treaty allowing the Germans to transit troops through Finland to Norway.

German aircraft used Finnish air bases, and the army launched Operation Reindeer which captured Petsamo. Despite these actions the Finnish government insisted it was neutral, but the Soviet leadership already viewed Finland as Germany's ally.

The Murmansk Oblast declared a state of emergency, mobilizing 50, soldiers and sailors. Conscripts and volunteers joined the newly formed 1st Polar Rifle Division , while sailors from the Northern Fleet enlisted in a marine infantry brigade.

Civilians were also employed in the construction of four lines of fortifications, between Zapadnaya Litsa and Kola Bay.

The Soviets proceeded to launch an air raid on 25 June, bombing all major Finnish cities and industrial centers including Helsinki, Turku and Lahti.

During a night session, the Finnish parliament voted to go to war against the Soviet Union and Operation Arctic Fox would begin within a week.

Arctic Fox began at midnight 1 July , when the Finnish 6th Division crossed the border. Soviet positions were heavily fortified and manned by divisions from the Soviet 14th Army: the nd Rifle Division , the th Rifle Division , and the 1st Tank Division commanded by Valerian A.

In daylight, facing Soviet resistance, both divisions sustained heavy losses and the attack failed, [1] [6] [26] with SS Nord Division faring especially badly.

The situation worsened the next day when, after a renewed assault, the Soviets counterattacked. This failure prompted the German command to rethink its strategy.

To reinforce the troops and replace the losses, additional personnel were transferred from the rd Infantry Division based in Southern Finland.

With a combined effort by all the German forces, extensive air-support by Luftflotte 5 , as well as a supportive flanking attack by the Finnish 6th Division, they finally broke through the Soviet defenses on 6 July and captured Salla.

A heavy Soviet counterattack drove them back out of the town but on 8 July, a general Soviet retreat of the nd Rifle Division allowed the German forces to recapture the town.

The Soviet troops had to leave most of their artillery behind and in the heavy fighting some 50 Soviet tanks were destroyed. Meanwhile, the Finnish 6th Division was making good progress in its flanking manoeuvre to the east to circumvent Kayraly and Lape Apa.

On 9 July, the th Division reached the town of Kayraly, but was thrown back by strong Soviet counterattacks.

All three Soviet divisions now formed a formidable defense line around Kayraly, incorporating the adjacent lakes Apa and Kuola into their defense.

The German advance stalled, facing difficulties with arctic forest fighting. At the same time the Soviets managed to bring additional reinforcements to replace their losses.

Feige relented and on 27 and 29 July the corps made two additional attacks separately against the Soviets which led to nothing.

Due to the grim situation, and mounting losses 5, men in just one month , AOK Norwegen finally ordered Feige to halt the offensive.

Beginning on 30 July, the Finns succeeded in smuggling a battalion over the lakes, behind Soviet lines, which allowed them to flank and subsequently defeat the Soviets on the other side of the canal.
