Rare animals Tundra
tundra regions of the world consists of fields, such as Russia’s Arctic, Antarctica, northern North America, Canada and Greenland. The environment is quiet, cold and sterile is the host of plants and animals resistant and adapted to their habitat. However, despite all its varying properties that allow them to survive in the cold snow-covered tundra, some animals are now endangered because of possible habitat loss and changes in global weather patterns. Consider some of the animals here.
Arctic Fox
Polar fox most captivating images of the tundra. Although not listed as an endangered species, with a population of several thousand, two subspecies of arctic fox has been placed on the list of endangered species. In Russia, the population Mednyi Fox Island had dropped to just 90 animals by the spread of the parasite by the common dog. Another population decline in the number of AA is in Finland, Norway and the Swedish territory. The fox population is destroyed by hunting and never recovered because they do not have a significant number of breeding pairs of animals. Small quantities are also sensitive to fluctuations in the availability of prey of foxes and outbreaks of disease. Other threats include the reduction of Arctic fox Arctic ice, which allows the red fox habitat area to enter the territory of the arctic fox and competition for food.
Polar bears
Polar bears are in Canada, Greenland, Norway, Russia and Alaska. Polar bears are considered vulnerable to population decline. Polar bears live in cold conditions to use reason to find and improve young people .. Rising global temperatures threaten to reduce the environment of polar bears and therefore the resources available to food. The next 50 years could see a dramatic decline in the number of polar bears live in the tundra zone with some scientists estimate that 50% of annual decline of sea ice in 2100. Although all species have demonstrated their ability to adapt to their environment, polar bears are highly specialized for life in the Arctic marine environment. Polar bears need a lot of time to educate young people to become independent adults. It is estimated that this time the parents of the age will be against the polar bear as a decrease in the quality of young sea ice bears are facing a higher risk in the exploration of poor conditions ice and subject to the risk of injury and death.
Caribou
Porcupine caribou in northern Alaska and the Central Arctic. These animals face the potential threat of a growing number of oil and gas and industrial development. A computer model of the Porcupine Caribou Herd has shown that the combination of snow during the winter and increased insect harassment can significantly reduce body fat of women. Because there is a strong correlation between body fat and the successful launch of autumn to spring, the projected climate change could reduce the birth rate caribou about 40 percent.
Caribou hunting is a big threat in the Russian Federation. Habitat loss to Finland, but the registry can cause problems in the future and there is no harassment of the species in some areas because of winter sports. Hybridization with the potential problem of semi-domesticated reindeer several subspecies and subpopulations and led the development of long, a high fence keeps deer two separately.
The deer meningeal worm port and release into the habitat that is usually fatal for deer and caribou, but clinically benign deer. Expansion of coyote prey populations threatened caribou herd in south-eastern Quebec. long-term decline in the population, live in the taiga of Ontario has been associated with the expansion of logging. Decrease of reduced food availability for predators such as wolves, caribou and damage the economic base of traditional indigenous North.
Narwhal
Narwhals found on the Atlantic coast of the Arctic. Name Narwhal means “corpse whale” because often swim on his back, motionless for several minutes. Narwhals in the summer months range from about two months in the high Arctic, shallow bays and fjords ice-free. During the winter there is more ice cover offshore along the continental slope environment. Narwhals migrate each year between the two regions with a seasonal migration takes about two months.
Narwhals listed as “threatened.” Although the exact number of lives day Narwhal is difficult to estimate the amount of debate that can be decreased because of climate change and hunting. narwhal is an animal that are important to the natives of the North Pole, because they provide the much needed vitamin C for your skin. One of the only sources of vitamin C for people who live there. Today, narwhals are hunted for their ivory tusks, which can sell for over 4000 dollars on the black market in Eurasia. There are some attempts to breed in captivity narwhals, but they rarely last more than a few weeks or months after capture. They are capricious and candidates holding the traditional economy in captivity breeding.important Greenland and durable.
So we see a major reason that animals cope with the pressure in the tundra of the Arctic is caused by the ongoing climate change. Many conservation programs have been established to help the animals to stabilize and increase their population once again. Some of the most beautiful landscapes that can be accessed on the Internet as the Canadian tundra Terraformers Conservation Foundation, the conservation of flora and fauna (CAFF), WWF Conservation Action Network and the Coalition finally Alaska.
