AB The epigeic fauna in the sink holes was studied using formaldehyde ground traps at 14-day intervals from April to October in 2002 and 2003. A total of 5 transects of traps have been installed within 5 selected areas of the northern part of the Moravian Karst. Areas within the district of Vilémovice, Lažánky and Ostrov near Macocha villages have been studied in particular. Sink holes have been selected on the basis of how they are probably influenced by human activities (types such as regularly mown sink holes within a thoroughly exploited field - 1, sink holes partially or totally overgrown by shrubs - 3 and 2, sink holes with fully developed trees - 4, sink holes within an intensely exploited meadow - 5.It was the aim of this study to determine the species composition of individual areas, numbers of individual species, differences among areas characterised by synoecological characteristics such as the dominance, Shannon-Wiener's index of species diversity, equitability, Jaccard's index of similarity and to try to express the degree of anthropogenic influence. Similarity of individual areas has also been evaluated by means of the cluster analysis (on the basis of the Jaccard's index).Eudominant species were Abax parallelepipedus, Anchomenus dorsalis, Carabus ullrichi, Microlestes maurus, Poecilus cupreus and Pterostichus melanarius. Species such as Aptinus bombarda, Licinus depressus, Molops elatus and Syntomus obscuroguttatus were the most important ones. The highest and lowest values of the index of species diversity were found in the area No. 4, and 1 and 2, respectively. Equitability was the highest and the lowest in the area No. 4 and 1, respectively. According to the Jaccard's index, areas No. 2 and 3, and No. 1 and 4 were the most and least similar ones, respectively. A total of 53.3%, 45.6% and 1.1% of species could, be classified as belonging to the group E, A and R, respectively. The group E represents eurytopic species inhabiting a large variety of habitats, the group A contains species of more or less natural habitats while in the group R there are species with the most narrow ecological valence. The highest index of community was in the area No. 4, while the lowest in the area No. 1.The total results and the evaluation of characteristics such as dominance, index of diversity, equitability, ecological bond to the habitat expressed by species classification of A, E or R and the index the carabid beetle community proves the fact that areas No. 4 and 5 are under the least anthropogenic influence.
