Communities of epigeic beetles (Coleoptera) in the different types of green belts in fields
ŠEBÍK, Jakub
SUMMARY The assemblages of epigeic beetles were studied in various types of agroecosystems in the submontaneous area of Novohradske hory (South Bohemia, Czech republic). The research took place in years 2009 and 2011. There were sown various types of crops, in the target places, on which were established either biobelts (research 2009) or permanent green belts with trees and shrubs (research 2011) in past. The aim of the study was to assess, whether or how these landscape structures influence epigeic beetles. The datas were gathered by sampling ground beetles with ground traps. The collected material was put then through identification and this was the base for assessing the parameters of landscape structures influence on epigeic beetles. These parameters were: the species diversity, the abundance and the ammount of relict species. It was collected 3099 beetles and it was managed to identify 54 species at all. The interest groups of invertebrates were ground beetles/carabids (Carabidae) and rove beetles (Staphylinidae). The results differed for both groups. The rove beetles were generally more abundant, than ground beetles and most of them were found in crops in the year 2009. The lowest numbers were caught in crops 2011. There was a quite remarkable contrast between these two results. The species diversity of rove beetles was too lower, than the ground beetles? one. The results of biodiversity seemed to be strange so as the abundance was. The diversity was the highest in the crops 2009 and the slowest in the crops 2011. Nearly the same diversity was found in biobelts, which are really different type of habitat. The carabids? abundance was not so oscillating like by the rove beetles. They were the most abundant in biobelts and the less in permanent belts. The abundance in crops in both years was nearly the same. The species diversity was highest in permanent belts and the lowest in crops in the year of 2009. The results about antropic influence on epigeic beetles assemblages, based on ecological characteristics of beetles, were eventually raised. It was established, that all the populations are strongly affected by human. The results say, that habitats like biobelt and permanent belt seem to have a positive impact on epigeic beetles assemblages, namely on relict or rare beetles survival. The results have very disparate and sometimes contradictory nature, thus cannot be sumarized.

Cílem práce bylo studium zastoupení a početnosti různých druhů epigeických brouků v biopásech. Cílem bylo zjistit přínos biopásů k biodiverzitě společenstev epigeických brouků. Sběr a vyhodnocení materiálu proběhlo v roce 2009. Výsledkem bylo zjištění určitého přínosu biopásů na druhové zastoupení a početnost druhů zejména ubiquitních druhů epigeických brouků.
