Variability of diversity of carabid assemblages (Insecta, Coleoptera, Carabidae) in pine forests (Pinetum myrtillosum) in the Belarusian Lake District
Abstract
As a result of the studies carried out in blueberry pine forests on mineral and peat soils in the Belarusian Lake District, differences in species diversity were revealed in the assemblgees of ground beetles in these two habitats. Analysis of α-diversity measures of ground beetles demonstrated that species richness and the number of individuals in samples were significantly higher (p < 0.05) in biotopes with mineral soils. A similar trend was shown by the values of Hill numbers (q 1 and q 2). The study β-diversity also showed high significant differences (ANOSIM; R = 0.728, p = 0.007) in the species composition of ground beetles in the two habitat types. The higher diversity of carabids in pine forests on mineral soils is due to a wider group of species with high relative abundance, including Pterostichus niger, Carabus hortensis, Calathus micropterus, Carabus arvensis, Pterostichus oblongopunctatus. Whereas in swampy pine forests, the main share of relative abundance is accounted for by two species Pterostichus niger (47.25 %) and Carabus hortensis (29.45 %), and most other species are rare. The species diversity of ground beetles according to the Shannon index has a direct significant relationship (p < 0.05) with the height of shrubs and pH, as well as an inverse relationship with the cover of shrubs.
