Description
Summary:Comparative analysis of the fauna of phytophagous beetles (Chrysomeloidea, Curculionoidea) on grassy slopes in the east of the Russian Plain and in the Cis-Ural Region was performed. The species richness, taxonomic and chorological structure, and specificity of 22 partial faunas were assessed along the latitudinal gradient from the taiga to the steppe zone. The slope faunas are shown to have extrazonal features and to function as refuges of rare species. The species richness of slope communities of phytophagous beetles increases 2–3-fold (from 105–174 to 283–303 species) from the taiga to the forest-steppe, largely due to an increase in the number and share of representatives of the steppe landscape-geographic complex. The ratio of the number of species of Curculionidae to that of Chrysomelidae changes from 1: 1 to 1.5: 1.
