Carabid communities (Coleoptera, Carabidae) in differently managed forage legume stands in the Podpoľanie region (Central Slovakia)

Abstract

The paper presents the results of studies on the communities of Carabids from the land registry area of the Očová village (Podpoľanie region, Central Slovakia). The research was carried out in two consecutive vegetation periods on two different agricultural plots with alfalfa (Medicago sativa L.): the first of them (locality Nadhájniková) was managed intensively, and the second one (locality Koteľnice) was characterized by a nature-friendly, low-input agro-environmental management form, without application of synthetic fertilizers and pesticides. On the studied sites, the observed species composition of Carabidae was similar. Neverthe-less, the higher total number of individuals and the higher species richness were typical for the nature-friendly managed plot in Koteľnice. On both plots, the highest abundances were reached in Poecilus cupreus, Pterostichus melanarius and Pseudoophonus rufipes. On the intensively managed plot in Nadhájniková, however, the abundances of all these species were markedly lower. Our results suggest that the studied component of epigeic fauna finds better ecological conditions on the sites with the nature-friendly management form.
