Spoločenstvá chrobákov (Coleoptera) v blízkosti rašelinísk PR Tisovnica a NPR Klinské rašelinisko (CHKO Horná Orava, Severné Slovensko)
The Communities of Beetles (Coleoptera) near the Peatlands at PR Tisovnica and NPR Klinské rašelinisko (CHKO Horná Orava, North Slovakia)

Summary/Abstract: The aim of this research is to map the community of beetles on selected peatlands in Horná Orava (PR Tisovnica – village Oravská Polhora, NPR Klinské rašelinisko, village Klin). On each of the peatlands were selected two ecotopically different locations (A, C – meadow and B, D – meadow / forest) were represented by flowering herbs from the families: Ranunculaceae, Asteraceae, Alliaceae, Fabaceae, and Brassicaceae. The etomological material was collected by the exhaustor and slipping grasslands during the vegetation period (May – October) in the year 2016. At the PR Tisovnica were 334 individuals (ex.) with 32 species (sp.). They belong to 9 families were registered in the herbage. The NPR Klinské rašelinisko showed a total of 386 ex. on flowering plant species with 9 species from 6 families. In PR Tisovnica, the highest values of dominance were the following eudominant species (ED): Apion apricans (22,2 %) from the family Curculionidae, Chrysolina fastuosa (12,9 %) and Chysomela coerulans (13,7 %) from Chrysomelidae. The NPR Klinské rašelinisko has eudominant (ED) species as Rhagonycha fulva (18,4 %) of the family Cantharidae, Cetonia aurata (16,8 %) of the family Scarabaeidae, Athous niger (13,7 %) of the family Elateridae, Strangalia maculata 12,7 %) of the family Cerambycidae and Otiorhynchus ligustici (10,7 %) of the family Curculionidae (Table no 1).The tables no. 2 and 3 shows the species representation of beetles, their abundance (dominance), cenotic charakteristic and their developmental and trophic binding to the flowering plant species.
