Arctic ground squirrel, Spermophilus parryii - Overview BBC Natural History Unit http://www.arkive.org
Copyright: dinets.travel.ru/chukotka.htm Brown or Siberian lemming, Lemmus sibericus They like to eat mostly arctic grasses and moss. At the start of the winter lemmings grow to very large claws on their front feet to help them dig a hole through the snow to reach their grass nests. They don't hibernate and have to spend the winter looking for food and moving to keep warm. Lemmings give birth in both summer and winter and most lemmings manage to live less than a year. Their population numbers go up and down a lot and there are tons of lemmings about every four years. Lemmings are really important food for snowy owls, falcons, weasels and other animals in the Arctic.

Their closest relatives are probably the Alaska marmot, found in the Brooks Range. Black-capped marmots currently live in three very isolated and spatially distinct populations. A common feature in all habitats is the plethora of rocks and dirth of vegetation. They are only active about three and a half months each year and they mature slowly. Dispersers wait for at least three years before they leave their natal group. Average litter sizes are around four, and sex ratios are a bit male-biased. Black-capped marmots and hoary marmots are the only two species occasionally found on cliff bands above the sea. Text from Marmotburrow, UCLA The Wolverine ranges from northern Europe and Siberia through northern North America, and since that includes Kamchatka, here it is: Wolverine, Gulo gulo, summer and winter Photo: Swedish Centre for School Biology and Biotechnology and Mont St-Hilaire Nature Center Wolverine, Gulo gulo The Wolverine ranges from northern Europe and Siberia through northern North America, and since that includes Kamchatka, here it is: One of the largest extant mustelids, Gulo gulo 's head and body length is 65-105 cm and tail length is 17-26 cm. Their weight is between 7 and 32 kgs. Females are at least ten percent smaller than males in linear measurements and 30 percent less in weight. Gulo gulo is reminiscent of a large marten with a heavy build, large head, relatively small and rounded ears, a short tail, and massive limbs. © http://www.ecosystema.ru/ Wolverines have long, dense fur which is generally blackish brown with a light brown band extending along each side of the body from shoulder to rump and joining over the base of the tail. Gulo gulo has keen senses of smell and hearing but fairly poor eyesight. Wolverines are extremely strong and aggressive for their size, and they have been reported to drive bears, cougars, and even packs of wolves from their kills. Text from "The Gulo Project" Kamchatka snow sheep, Ovis nivicola nivicola Photo: Victoria Travel Co. Ltd Kamchatka snow sheep, Ovis nivicola nivicola © http://www.ecosystema.ru/ Usually darker in color than the other snow sheep and lacking a white (or light) forehead patch. Horns on average have heavier bases than the mainland snow sheep which has caused some to call this subspecies the Kamchatka bighorn. This is incorrect because they are still a thinhorn species with horns similar (or identical) to the Dall or Stone Sheep of North America. Text from: http://www.wildsheep.org filin.km.ru/mammels/cunitsa1.htm and from Laura Leighty's Sable page Sabel, Martes zibellina There is sexual dimorphism between males and females. Males have a body length which is longer than females and they also weigh more than females. Males weigh between 880-1800 grams while females weigh between 700 and 1560 grams. The winter pelage is longer and more luxurious than the summer coat. Fur color ranges from light to dark brown. The color of their fur is usually lighter on their belly and darker on their back and legs. Individuals also display a light patch of fur on their throat which may be gray, white, or a pale yellow. The Sable exhibits delayed implantation. They mate during the spring and implantation occurs eight months later in the female. Where individuals are scarce; males exhibit courtship rituals such as: jumping, running, and "cat - like rumbling." Violent competition occurs in areas abundant with males. The females have a gestation period of 250 - 300 days and give birth to 1 - 7 altricial young. The young are weaned at 7 weeks and reach sexual maturity at 2 - 3 years. In most cases paternal care has been observed. The male protects the territory and has even been seen bringing food to the female and her young. more to follow A complete fur coat is currently being sold for US $36,000, so why shouldn't you go hunting? However, if you don't know why you should NOT, I can't help you. From Laura Leighty's Sable page Photo: © http://www.naturschule.com Euro-asian otter, Lutra lutra The Euro-asian otter, (Lutra lutra), has the widest distribution of all otter species. Its range covers parts of three continents: Europe, Asia and Africa. Otters spend most of their lives in freshwater. They inhabits rivers, lakes, streams, ponds and along rocky coasts. It uses a variety of shelters, such as, crevices in rocks and under the roots of trees but it mainly uses dens called "holts" where the females give birth and bring up their young. The holt has a chamber above the level of the water and an exit under the water. There is also a air shaft connecting the chamber to the surface which opens out into the thick thorny bushes or brambles. © http://www.ecosystema.ru/ The diet of the Euro-asian otter is varied. It feeds upon fish, eels, insects, aquatic birds, frogs, small mammals and crustaceans. Euro-asian otters found living along coastal waters have been found to feed mostly on crabs and dogfish. The hunts mostly at night, cornering their prey in weeds and catching them in their mouths.
