Where the most powerful tides break the iceArctic Ocean, forming polynyas and cracks, and the bottom warm Atlantic flow brings a large mass of fish, shellfish and plankton, inhabited by a small number of animals.
Mostly small mammals inhabitthe vast expanses of the tundra. Especially typical for this locality are such inhabitants as the Siberian and Ob Lemminge, as well as the Middendorf voles, inhabiting the western tundra. In the southern regions of the country there lives a vole of a housekeeper, and in areas with a drier soil there lives a narrow-field voles.
Let us examine in more detail the unusual inhabitants of this region.
Amazing animals of the tundra are lemmings. These are small rodents with hoofs. Their numbers are constantly subject to fluctuations (with a periodicity of four years). One can count up to one hundred animals per hectare during the years of mass reproduction, whereas in the years of recession, it is difficult to find one. The number of predators feeding on lemmings directly depends on the number of these small rodents. Seagulls, gyrfalcon, skuas, ermines do not bypass this prey, adding them to their diet consisting of several species of ground squirrels and voles.
These tundra animals are the main food forall predators of this habitat. Vole voles and lemmings are the main diet for white owls and polar foxes. A large mass of these small rodents is eaten and large seagulls.
No less amazing animals are tundras - arctic foxes. The main element of the fur-mining in these places is this charming predator. Despite this, the fur world is diluted by ermine, wolverine and weasel. In the southern tundra dwells and fox. In places in the tundra of Yamal a wolf can meet, which concentrates mainly in places of congregations of numerous domestic deer herds. Gydan and the extreme north of Yamal have a small number of reindeer herds, and the White Island and the Arctic tundra are even less used by local reindeer herders for growing livestock.
Animals of the tundra are activebegin with the first rays of the spring sun. In the spring, the tundra is not recognized! A huge number of birds fly here for nesting. Numerous swamps, lakes and deep rivers attract them to their abundance of food. The entire district is filled with noise and screams, because you have to catch everything before the cold.
These amazing animals of the tundra (arctic foxes, wolves,reindeers and musk oxen) were able to find an adaptation to the harsh conditions of life among ice and snow. Do not differ from them and walruses, seals, polar bears.
Sea giant, walrus - fast and tirelessswimmer. He, like a powerful torpedo, rushes in the water column. Walrus for several days can not get out on land. These are truly amazing animals of the tundra, which rest and even sleep in icy water. Due to inflated throat bags, it is able to stay close to the surface of the water. Interestingly the fact that he has only subcutaneous fat is almost half a ton, and his fangs are able to protect even from the attack of a polar bear.
The animal world of the tundra has one morerepresentative, which symbolizes power and endurance. It is a polar bear, rightfully recognized as the owner of the Arctic. A strong and powerful beast in this natural and climatic zone is the largest representative of the terrestrial animal world. Some individuals can reach up to 1 ton of weight. The most formidable of his weapons are healthy clawed paws. In one stroke, he is able not only to kill the seal, but also to stun a large harp seal. Yes, animals in the tundra can stand up for themselves and survive under any circumstances.
Favorite favorite food of this formidable handsome man -seal oil. He is a very patient hunter, able to hunt down prey for hours, lying on an ice floe near a small polynya. He is an excellent swimmer and, if an opening in the ice allows him, can catch his prey in the water. A thick coat and an impressive supply of subcutaneous fat do not allow it to freeze. It is very interesting that in such giants bear cubs are born in the size of everything from a palm.
Such an exciting life is spent by animals in the tundra.
