A lemming is a small rodent, usually found in or near the Arctic in tundra biomes.Lemmings form the subfamily Arvicolinae (also known as Microtinae) together with voles and muskrats, which form part of the superfamily Muroidea, which also includes rats, mice, hamsters and gerbils.
The lynx creates its den in crevices or under ledges. It feeds on a wide range of animals from white-tailed deer, reindeer, roe deer, small red deer, and chamois, to smaller, more usual prey: snowshoe hares, fish, foxes, sheep, squirrels, mice, turkeys and other birds, and goats. It also eats ptarmigans, voles, and grouse.
The mountain hare is regionally the favourite prey of the golden eagle and may additionally be preyed on by Eurasian eagle-owls and red foxes. Stoats may prey on young hares. [10] In southern parts of Finland, Norway, and Sweden, the mountain hare and the European hare compete for habitat.
Their long tails, covered with scales rather than hair, are laterally compressed and generate a small amount of thrust, with their webbed hind feet being the main means of propulsion, [3] and the unique tail mainly important in directional stability. Muskrats spend most of their time in the water and can swim underwater for 12 to 17 minutes.
[7] [42] A more detailed glance at Finnish Lapland showed that amongst 2,062 prey items, 32.5% of the foods were Norway lemmings (though in some years the balance could range up to 58.1%), 28% were grey red-backed voles (Myodes rufocanus) and 12.6% were tundra voles, with birds constituting a very small amount of the prey balance (1.1%).
