Abstract

Ecological structure of ground beetles and its dynamics during the transition of ground beetles from one habitat to another due to felling and subsequent reforestation were studied. The regularities in the formation and development of ground beetles community in the early stage of secondary succession on the felling site were determined. The simplest indices of diversity, species abundance, distribution and dominance were used. Species richness of ground beetles on the felling site increased from 28 to 41 species a year after felling. In four years it decreased to 36 species. According to the ecological preference, the basis of the ground beetles complex on the forest site before felling was formed by spring-breeding forest species. Four years after felling the proportion of forest species decreased from 73,4 to 65,7 %, and the significance of forest-marsh species and meadow-field species increased. The number of summer-breeding and autumn-breeding species also increased. The species and quantitative composition of ground beetles on the felling area during the first year was mostly determined by a neighboring forest. In the following years a separate biocenosis was formed on the site, and the influence of the forest diminished.
