Экологическое разнообразие стафилинид (Coleoptera, Staphylinidae) в сосновых культурах на охраняемых территориях Беларуси

Abstract

The comparative analysis of the staphylinid beetles’ ecological diversity in pine plantations on the three reserved territories, Berezinsky biosphere reserve, National parks «Belowezhskaia pushcha» and «Pripiatsky», has been carried out. The beetles were collected by means of pitfall trapping. Margalef, Shannon, Simpson, Berger - Parker indices and a parameter of log-series were used for estimation of ecological diversity. The correspondence of species abundance distributions to the log­normal model, log-series and broken stick models has been tested. The most significant differences concerned the dominant structure in the beetle communities. The composition of dominant species was different on all territories. Two species only, Staphylinus erythropterus and Ischnosoma splendidum. were dominants in all sites. Species richness of staphylinid beetles was the highest in the pine plantations in Berezinsky reserve, the lowest - in the plantations in Belowezhskaia pushcha.
