“…This species was relatively rare (4.6%) in herbaceous forests growing in the upper part of the mountain forest belt, but its abundance increased again in green moss forests growing in the middle part of this belt (16.7%), where rock outcrops are common. Berdyugin (1999) noted the "stratified" distribution of bank voles on the eastern macroslope of the Northern Urals. A similar distribution is characteristic of this species on the western slopes, but its pattern is slightly different.…”

“…The proportion of bank voles in catches increases from 28.0% in the mountain forest belt to 43.4% in the subgoltsy belt. Such a distribution as well as a relatively high density of bank voles (and some other species) are explained by the fact that, because of thermal inversion, plant communities with nemoral features, which are optimal for some species (in particular, western palearctic species), have developed at higher elevations than forest ecosystems of the boreal type (Berdyugin, 1999).…”

“…Corresponding studies have been performed mainly on the eastern slopes of the Urals, where environmental conditions differ from those on the western slopes. Moreover, they mainly concern individual taxonomic-cenotic groups, insectivores (Sharova, 1992;Bol'shakov et al , 1996) or rodents (Berdyugin, 1999), whereas studies on the entire complex of small mammals are relatively rare (Kulikova and Bol'shakov, 1984).…”

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.

“…Distribution area borders of several species lay in the region: Apodemus uralensis, Apodemus agrarius, and Microtus arvalis are present in the southern part (up to 60 N), and the southern edges of Microtus middendorffii and Ochotona hyperborea areas reach the northern part of the North Urals. Dominant species in the rodent communities are voles of the genus Clethrionomys (Gromov and Erbajeva, 1995;Berdyugin, 1999;Bolshakov et al, 2000).…”

a b s t r a c tData on fossil micromammals known at present from the North Urals sites allow us to trace the history of rodent communities beginning from the Middle Weichselian up to the present and to reveal some temporal and spatial patterns in their changes. Five fauna types were distinguished among the fossil local faunas known at present. Throughout the Late Pleistocene only tundra-steppe faunas existed in the North Urals, which differed in time and space mainly by relative abundances of three dominant speciesDicrostonyx gulielmi, Microtus gregalis and Lemmus sibiricus, and in some cases by species diversity. Early and Middle Holocene faunas reflect a transition from communities characteristic of tundra-steppe to forest and, in particular, taiga environments. Late Holocene faunas have a typical taiga character. Tendencies of temporal dynamics of faunas correlate with those revealed for other parts of the Urals. Differences between faunas of the different slopes (western and eastern) of the North Urals can be explained by the same factors which determine the different climate conditions there at present.

“…The fauna of rodents and insectivores of the Pechora-Ilych Reserve located 80 km northwest of the Vishera Reserve were described in detail (Teplov and Teplova, 1947;Teplov, 1960;Bobretsov, 1986Bobretsov, , 1989. Small mammals were studied by Chernyavskaya (1959) and Berdyugin (1999) 20 km to the southeast, in the Denezhkin Kamen Reserve.…”
