    Abstract:
    Ecological features and circadian activity of the common vole sibling species were studied upon joint and separate occurrences. Both species had a similar abundance but different biotopical distribution. Microtus arvalis--chromosome form "obscurus" populated the studied territory more uniformly the studied territory. M. rossiaemeridionalis tended to occur in humid coenoses. In case of joint occurrences, the sibling species occupied different regions of biotopes and the rhythms of their activity change, as a rule, in antiphase. Separation of the spatial and temporal niches of these species is considered as possible avoidance of competition between the closely related species.
