- Abstract
The materials of our studies on the taiga shrew (Sorex isodon Turov, 1924) in the northeastern part of European Russia are summarized. Its distribution is shown to coincide generally with the northern border of the taiga zone. The optimal biotopes are grass spruce forests (only for them are the values of the biotope fidelity coefficient positive). The numbers of taiga shrews in lowland localities are 0–2.4 individuals, while in foothill habitats it increases up to 4.4–8.6 individuals and reaches maximum values on the western slope of the northern Urals (28 individuals per 100 cone-nights). The formation of the numbers of the species is much influenced by the landscape conditions of the territory: the ratio of habitat types and their areas. An increase in the area of grass forests leads to an increase in the abundance of taiga shrews.
