Abstract

Carabid beetles (Coleoptera, Carabidae) were studied at abrupt and gradual forest edges, and in the Dinaric beech-fir forest interior (as. Omphalodo-Fagetum) near the village Stara Sušica (Gorski kotar). Beetles were collected by pitfall traps from May to November 2010. A total of 9 789 specimens represented by 52 species were collected. Carabid beetle diversity was significantly higher at the forest edges than in the forest interior, which is in accordance with the classical ecotone hypothesis. The opposite trend was detected for carabid beetle activity density. High activity density in the forest interior was primarily caused by extremely high abundance of Nebria dahlii. Hierarchical cluster analysis reveals high similarity between carabid beetle assemblages of the forest interior and its edges. Mean individual biomass (MIB) was significantly higher at the edges than in the forest interior due to the dominance of large-sized carabid beetles at the forest edges.
