Ecological peculiarities of small mammals from different ecological groups in agrocenoses of foothills in the Central Caucasus

The numbers, sex-and-age structure and reproduction of two background species in agrocenoses of foothills in the Central Caucasus were studied. The adults of this year represent the population nucleus of Apodemus uralensis and Mus musculus, which symbiotopically occur in agrocenoses in summer. All the cohorts are present therewith in the age structure of A. uralensis in contrast to M. musculus, when a low proportion of hibernating animals or their full absence is observed. The high numbers and labile reproduction characters of A. uralensis testify to safe state of the population in habitats under moderate anthropogenic impact.
