Ecological and faunistic characteristics of meadow-steppe taxocenes of collembola of the Eastern Podillya

A comparative analysis of the taxonomic and ecological structure meadow-steppe collembolan taxocenes Eastern Podillya was carried out. 77 species Сollembola belonging to 41 genera 14 families were found on studied territory. From 6 18 collembola at level point alpha diversity, 40–42 coenotic which indicates a large capacity soil environment for in this type biocenoses Podillya. The investigated Collembola are characterized by average population density indicators, from 5.8 9.1 thousand spec./m2. It that dominance, spectra life forms biotope groups have their own specificity, due local edaphic conditions, as well degree anthropogenic transformation. showed that, terms richness, complexes xeroresistant (47.6–60 % total richness) mesophilic (17.5–35.7 %) prevail collembola. include six species. group open landscape (meadow-steppe, meadow steppe) prevails, share composition is 52.4–62.5 diversity. According indicator relative abundance, 44.4–64.8% belong feature presence 7.1 15 atmobiotic inhabit macrophytes surface loose leaf litter carry out regular daily migrations grass, trees shrubs, about 5 corticolous species, ecologically related lichens, mosses, tree bark stone substrates. established all three phytocenoses Podillya, specialized taxocene formed, where more than 40 has xerophytic grass groups.
