Porovnání fauny slíďákovitých pavouků pastvin skotu a ovcí v okolí Nasavrk
 Blažek, Jiří
The main target of my diploma thesis was the comparison of wolfspider fauna on cattle and sheep grazing pastures. For this reason I laid pitfall traps at these pastures during three months of 2017. I collected pitffall traps every month. Totally I got 90 samples. 3418 spiders were caught in total, from this 1164 individuals belonged to wolfspiders. I determinated all adults wolfspiders and sorted them into 6 species. Ammount of spiders and wolspiders of course varied during the time of study. The most abundant month was May (2532 spiders, 876 of wolfspiders), the number of caught spiders was decreasing rapidly in following months. The most numerous wolfspider spieces was Pardosa palustris (77 % of all wolfspiders). No red list or rare species of wolfspider was caught. Results of study prove that abundance or species diversity of wolfspiders isn´t influenced by species of grazing animal. But intensity of grazing has influence on species diversity and abundance of wolfspiders and spiders generally. Both indicators are decreasing with increas of grazing intensity.
