Видовое разнообразие жуков стафилинид (Coleoptera, Staphylinidae) в сосновых культурах разного возраста в Березинском заповеднике

The study has been carried out in the pine plantations of two age classes (II class - 37 years old III class - 55 years old), forest type Pinetum pleuroziosum. The beetles were collected by means of pitfall trapping. Indices estimating species richness and species domination were used for measuring the species diversity. Totally 55 staphylmid species were found in the pine plantations in Berezinsky reserve. The dominant structure in the staphylimd assemblages is changed depending on plantation age Staphyiimd species diversity decreases in older plantations
