Communities of small mammals in specially protected natural territories of the south of the Tyumen region

Promotorova Elena

The increasing anthropogenic impact on specially protected natural areas makes monitoring of small mammals as an indicator of the intensity of ecosystem disturbances more and more relevant. This paper presents the faunal composition, abundance, diversity indices and the proportion of small mammals living on the territory of six natural monuments of the Tobolsk district of the Tyumen region. The collection of material was carried out from May to August in 2019-2020 by methods of trap grooves and trap lines. 6 species of insectivores and 10 species of rodents were found. The basis of rodent communities was the red vole (Myodes rutilus Pallas, 1779), insectivores - the common brown-tooth (Sorex araneus L., 1758). The greatest species diversity and abundance of small mammals were noted in the protected area "Medyanskaya Grove", the minimum indicators were observed on the territory of the natural monument "Panin Hill". Among the ecological groups of small mammals in the study area, neutrals predominate.
