Chrobáky (Coleoptera) a ich viazanosť (fidelita) na choriotop kvitnúcich rastlín v oblasti Oravskej Magury (CHKO Horná Orava, Severné Slovensko)
The Beetles (Coleoptera) and their Fidelity to the Flowering Vegetation on the Site of Oravska Magura (CHKO Horna Orava, North Slovakia)

Summary/Abstract: The aim of this paper is to determine the fidelity of beetles on the choriotop of the flowering plants in selected mountain meadows at Oravska Magura (Magurka, 1 107 Meter, in: CHKO Horna Orava, North Slovakia). In the study area were chosen two habitats (A – 620 Meter, B – 655 Meter) which represented the flowering herbs of the families: Asteraceae, Ranunculaceae, Fabaceae, Apiaceae and Lamiaceae. The entomological material we acquire method with use the exhaustor and slipping grasslands during the vegetation period (May – October) in the year 2014. We counted approximately 373 ex. of beetles. They belong to 11 different species originating from 6 different families. The dominant praticol families were: Curculionidae 169 ex. (45,3 %), Buprestidae 79 ex. (21,2 %) and Chrysomelidae 69 ex. (18,5 %). The eudominate species of beetles bound to the flowering plants belong to the number with 58 ex. (15,5 %) of Liparus glabrirastris (in Petasites hybridus), 52 ex. (13,9 %) Apion apricans (in Trifolium pratense), 51 ex. (13,7 %) Anthaxia nitidula (in Hieracium umbellatum) and 44 ex. (11,8 %) of Cassida viridis (in Lamium purpureum), which are a occurrence on two mountain grasslands. The question remains at selected sites to evaluate the quantitative and qualitative representation of beetles, their dominance, seasonal dynamics, and cenothetic features of the study area. 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.
