Vliv intenzity managementu umělé obnovy dubových porostů na interakci mezi pavouky a jejich kořistí
 Kárych, Jan
The aim of the research was to determine the effects of intensive management carried out by milling and full-scale treatment and extensive management during the preparation and care of artificially regenerated oak stands on the trophic networks of web spiders and their prey, which are sensitive to changes in the vegetation cover and canopy structure or openness. The procedure for evaluating the results was divided into two parts. Food webs were investigated in the field by collecting spiders and their webs with prey in plots during a total of two collections in June and August of 2021. Subsequently, from the collected samples, individual representatives of spiders were determined at the level of species or genera. The prey of spiders was determined at the level of orders or suborders. The obtained data were processed using statistical methods and evaluated. The results show that the amount of data was not optimal, but it confirmed the assumption that the total numbers of spiders and their prey were significantly higher on unmilled areas, as well as the species diversity, than on milled areas.
