Structure of the communities of small mammals (micromammalia) in forests on western slopes of the Northern Urals

Long-term data on the species composition and ratio of insectivores and rodents in forest ecosystems of the western macroslope of the Northern Urals are considered. It is shown that the micromammalian communities of mountain forests are characterized by higher total abundance and polydominance and comprise greater numbers of common species than the communities of taiga forests in neighboring regions of the Russian Plain. Hence, the mountain-forest communities of small mammals have high indices of species diversity and uniformity.Translated from Ekologiya, No. 2, 2005, pp. 138–145.Original Russian Text Copyright © 2005 by Bobretsov, Lukyanova, Poroshin.
