Dispersion of the epigeic fauna groups in the agricultural landscape

Abstract

Changes in the structure of epigeic animal groups indicate ecological stability, which are influenced by urbanization, agriculture, and forestry. The aim of the paper was to assess the impact of agrarian land in the vicinity of urban and suburban landscape and non-fragmented forest in the vicinity of rural landscape on the occurrence of epigeic groups. We recorded the pitfall traps - 19, 676 individuals belonging to 20 taxonomic groups at 9 localities representing 7 types of habitat. Our results indicate a year-on-year increase in the number of individuals of epigeic groups in the city, with surrounding agrarian land. We found a correlation between eudominant epigeic groups of Aranea and Hymenoptera and rural landscape with the non-fragmented surrounding. Coleoptera has shown a link between the conditions of urban and suburban landscape with the surrounding developed agriculture. We confirmed a statistically significant effect for luminosity (p = 0.002), humidity (p = 0.025) and pH (p = 0.017).
