title: [Certain aspects of interactions between cohabiting sibling species Microtus arvalis and M. rossiaemeridionalis].
abstract: Some aspects of interspecific interactions between sibling species of common vole were studied at the Chernogolovka Scientific Research Station (Severtsov Institute for Problems of Ecology and Evolution, Russian Academy of Sciences) from 1992 to 2001. In the marking plot and indoors, East European vole demonstrated high tolerance to the anthropogenic stress considering that it was the most abundant species in the studied area transformed by human economic activity and that it used buildings as temporary shelters. When cohabiting the marking plot, common and East European voles demonstrated different territorial distribution and circadian activity, which can be considered as an adaptation to avoiding competitive interactions of ecologically similar species.
