Ovplyvňuje slnečný svit (heliofília) skladbu koleopterocenóz lúčneho biotopu? (CHKO Biele Karpaty, Veľká Javorina, západné Slovensko)
The Affect of Sunshine (Heliofilia) at the Community of Beetles in the Grassland Habitats (Biele Karpaty, Velka Javorina, Western Slovakia)

Summary/Abstract: The aim of the research is to determine the impact of the various effects of sunlight (heliofília) on quantitative-qualitative representation of beetles to areas with meadow vegetation with different light and weather conditions depending on different points of the compass (north, peak and south). We selected three sites of studied meadow biotop, located in the Biele Karpaty. The first studied area (A) is located on the southern side of the highest peak of the Biele Karpaty – Veľká Javorina (910 m), the second area (B) represents the peak of the Veľká Javorina (969.8 m) and the third area (C) is located on the northern slope of the hill (910 m). The aim of our analysis is to evaluate the quantitative and qualitative representation of beetles, their dominance, cenotic characteristic to the study area and seasonal dynamics of the growing season (April – October) in 2015. Entomology material was obtained by the method of sweeping grasslands. We counted approximately 429 ex. of beetles. They belong to 40 different species (spp.) originating from 10 different families. The greatest differences were found between southern and northern habitats, while habitat A (south) has proved to be the most stable and richest represented meadow environment with species from all 10 families (175 ex., 27 spp.) and habitat C (North) as a generic poorest meadow environment, represented by the species from 7 families (99 ex., 16 spp.). On the all three stacionars of meadow dominated the praticol family of beetles: Chrysomelidae.
