Abstract

Feces of 26 karyotyped vole specimens (Microtus arvalis arvalis, M. arvalis obscurus, M. levis (rossiaemeridionalis), and M. agrestis) from natural biotopes of the central chernozem zone have been examined to identify 4968 cuticular fragments of 36 plant species and 7 plant parts. Their analysis has shown that the diet of voles depends not so much on the consumer species as on the composition of plants in the foraging area. Voles differ more significantly in terms of what plant parts they consume: M. arvalis arvalis and M. arvalis obscurus more frequently feed on generative plant parts, while M. rossiaemeridionalis shows the highest preference for green parts.
