Differentiation of ground invertebrate communities in urban environment (Kaluga, Russia) We have collected arthropods with pitfall traps and identified them to order or to family. Classification of arthropod communities reflects habitat properties, if we survey herpetobionts sensu lato (as biocenotic layer). And there is no satisfactory classification, if we consider herpetobionts sensu stricto (as life form). Differentiation of arthropod communities in urban area is influenced mainly with density of canopy.

Phylogeography of house mice Mus musculus in Russia and adjacent territories and role of invasions Using a phylogeographical approach based on the reconstruction of mitochondrial DNA, we attempt to determine the expansion and genetic diversity of different subspecies of M.musculus in Russia and adjacent territories. The study of genetic distances demonstrated existence of two phylogenetic lineages of Mus musculus distribuited in Russia and adjacent territories. The first lineage includes the house mice of Transcaucasian hybrid zone and populations of M.m.musculus subspecies from Moscow region, the second ones include populations of subspecies M.m.musculus and M.m.wagneri from the south of West Siberia and the south of Volga river region.
