The real lemmings ( Lemmus ) are a genus from the Lemmini tribe . Depending on the doctrine, there are three to five types:
- Berglemming , Lemmus lemmus , Scandinavia , Kola Peninsula
- Siberian lemming , Lemmus sibiricus , Siberia
- Brown lemming , Lemmus trimucronatus , arctic regions of Alaska and Canada
- Pribilof lemming , Lemmus nigripes , Pribilof Islands
- Amur lemming , Lemmus amurensis , eastern Siberia from the Amur basin to Kamchatka
Often the brown lemming and the pribilof lemming are assigned to the Siberian lemming as subspecies.
The species of this genus inhabit the arctic tundras . They are known for the migrations that they undertake due to the intermittent population pressures . These migrations and the sharp fluctuations in population density that were also observed led to a theory of “mass suicide” in Scandinavia. Although it is incorrect according to the current state of knowledge, it is still supported. The Disney "documentary" White Wilderness , which took up and recreated this theory, also contributed to this. The only truth is that many animals do not survive these migrations in search of new habitats.
