Distribution of Small Mammals (Eulipotyphla, Rodentia) in the Gradient Direction Urban–Suburban–Rural of Central Slovakia

Abstract

Changes in the structure of small mammals’ communities (Eulipotyphla, Rodentia) along urban–rural gradient indicate the environmental state of stability or instability. Since small mammals are important with regard to the transmission of diseases to man and domestic animals, therefore knowledge of their association with the landscape structure is needed in land use planning. In course of the period from 2015 to 2017, there were recorded 109 individuals belonging to 15 species at 9 study sites (3 rural, 3 suburban, and 3 urban). We recorded a decrease in the average number of species in the direction of the suburban–urban–rural gradient. The number of individuals decreased in the rural–urban–suburban gradient. Eudominant species Clethrionomys glareolus (D = 20.2%), Microtus arvalis (13.8%), and Sorex araneus (19.3%) preferred the close links between the terms of the rural landscape, while Apodemus agrarius (D = 11.9%) and Sorex minutus (D = 11.0%) preferred the close links between the terms of the urban landscape.
