  Norway lemming - Wikipedia, the free encyclopedia
The Norway lemming dwells in tundra and fells, and prefers to live near water.
The Norway lemming has a dramatic 3-4 year population cycle, in which the species' population periodically rises to unsustainable levels, leading to high mortality, which causes the population to crash again.
In typical years, the Norway Lemming (which is the one that is said to be the suicidal species) spends the winter in nests under the snow.

 Lemming
Lemming populations go through rapid growths and subsequent crashes that have achieved an almost legendary status, largely because of the well-known Disney Studios film, White Wilderness[?], which was produced in 1958 and reappeared on television at regular intervals for many years afterwards.
As a grand finale, the captive lemmings were herded over a cliff into a river (in the film, this was the "sea", and the herded lemmings were on a "suicide drive").
In fact, the behavior of lemmings is much the same as that of many other rodents which have periodic population booms and then disperse in all directions, seeking the food and shelter that their natural habitat cannot provide.

 Norway Lemming   (Site not responding. Last check: 2007-11-01)
Norway lemmings are colourful little animals with patches of fl, tan and reddish-brown fur.
Norway lemmings live in Norway, Sweden, Finland and extreme northwest Europe, in northern alpine and the open, swampy flatlands of the tundra.
Although lemmings can swim, they sometimes try to cross bodies of water that are too deep and too wide to swim across (for example, the sea) and so they drown in large numbers, because they can only swim for 15 to 25 minutes before becoming exhausted.

 Nature in Finland — Virtual Finland
The Norway lemming’s range is limited to the arctic fells and tundra of northern Fennoscandia — where it is found in north-westernmost Russia and northern parts of Finland and Sweden, as well as in Norway.
The numbers of Norway lemming in northernmost Finland vary greatly from year to year, but during good lemming years these small animals seem to pop up everywhere, especially on migration between their winter and summer feeding grounds.
Lemming populations can increase during periods when there are relatively few predators; but predator populations will then increase, and consume more lemmings, soon causing a downturn in their numbers.

Norway's fauna and flora have been strongly influenced by the new incursions, but also by the fact that the climate is the prime factor in determining distribution patterns.
Norway has perhaps one of Europe's most variable climates, due to its proximity to the Atlantic and to its 2,500 km long coast, along a north-south axis.
In Norway, as in the rest of Europe, it is the seed ripening that deter-mines the limits of their distribution.

 Great Moments in Science - Lemmings Suicide Myth
One myth deeply entrenched in our language is that of the "Lemming Suicide Plunge" - where lemmings, apparently overcome by deep-rooted impulses, deliberately run over a cliff in their millions, to be dashed to their deaths on the rocks below, or to drown in the raging ocean.
So lemmings do have their regular wild fluctuations in population - and when the numbers are high, the lemmings do migrate.
The migration sequence was filmed by placing the lemmings on a spinning turntable that was covered with snow, and then shooting it from many different angles.

 Steppe Lemming
NATURAL PREDATORS Steppe Lemmings are the staple diet for many of the mammalian and avian predators of the steppe, particularly owls, Rough-legged Buzzards (Buteo lagopus), Corsac Foxes (Vulpes corsac), polecats (Mustela putorius), stoats (Mustela erminea), weasels (Mustela spp.), and gulls (Larus spp.).
DIET As the Steppe Lemming bears a superficial resemblance to the Russian Dwarf Hamster, there is a temptation to treat it as such, particularly in respect to its diet.
Steppe Lemmings were first bred (in the laboratory) about 1940 in the former U.S.S.R. From there colonies were established in the early 1960s in Germany and Great Britain for research on such diseases as tularaemia (an acute bacterial infection which causes fevers, chills and inflammation of the lymph nodes), listeriosis and poliomyelitis.
