- Abstract
Small mammals were sampled along altitudinal gradients in the Rila Mountain, South-Western Bulgaria. Species composition varied according to altitude and habitat with a total catch of four rodent and one shrew species. Population number, sex and age structure and some morphophysiological parameters of the yellow-necked wood mouse (Apodmus flavicollis), bank vole (Clethrionomys glareolus), pine vole (Pytimis subterraneus), as well as the common shrew (Sorex araneus) from forest and grassland habitats and snow vole (Chionomys nivalis), yellow-necked wood mouse (Apodmus flavicollis) and pine vole (Pytimis subterraneus) from the alpine zone were studied. Correlations were found between abundance of rodent species and habitat variables, particularly vegetation structure, diet, cover of rock and microhabitat.
