Abstract
The purpose of the research was to assess the species composition and biodiversity indices for xylophagous beetles collected by window traps in the parts of Gomilshanski lisy National Nature Park with different management regimes and anthropogenic load. Four window traps were placed in each of the five groups of sample plots: clear felling, selective felling, stationary recreation, regulated recreation and protected zone. The data were analysed using the statistical software package PAST, particularly, the Menhinick index (DMn) and dominance index (D) were evaluated and classical clustering (unweighted pair-group average [UPGMA]) was performed. A total of 42 species of xylophages (9903 individuals) were collected from Curculionidae (Scolytinae and Cossoninae), Cerambycidae, Histeridae, Bostrichidae, Buprestidae and Lymexilidae. The highest species richness was in the plots of clear and selective felling (25 and 22 species, respectively) and the lowest was in the protected zone (16 species), regulated recreation (19 species) and stationary recreation (22 species). The Menhinick index (DMn) was the lowest in the protected zone (0.27), increased in the zone of regulated recreation (0.43) and stationary recreation (0.45) and was maximal in the plots of selective and clear felling (0.69 and 0.77, respectively). The number of individuals was maximal in the protected zone and minimal at the plots of selective and clear felling. All sites were dominated by Xyleborinus saxesenii (Ratzeburg, 1837) (66–85% individuals) and Anisandrus dispar (Fabricius, 1792) (8.5–20.7% individuals). Minimal dominance (0.49) was found in the plot of clear felling. Cluster analysis showed similarity of the xylophage complex in the plots of clear and selective felling, as well as in the zone of stationary and regulated recreation, which differed from the protected zone.
