Peculiar features of small mammal community structure on different macroslopes of the Northern Urals

摘要

Small mammal (Micromammalia) community structure on the western and eastern macroslopes of the Northern Urals is analyzed using the example of the Pechora-Ilych and Denezhkin Kamen' nature reserves. The landscape conditions of these areas strongly differ, largely determining the peculiar features of small rodent communities. Polydominant communities with high abundance of many species are formed on the humid western slopes. The abundance of communities on the eastern slopes is smaller and the proportion of dominants is greater. The small mammal communities of this region are similar in a number of parameters to the small mammal communities of the adjacent plains.
