Abstract

Carabid beetles (Coleoptera, Carabidae) were studied by pitfall traps in the Dinaric beech-fir forests (as. Omphalodo-Fagetum) in the Čorkova uvala virgin forest (NP Plitvice Lakes) and in the managed forest (Gorski kotar) during two years. A total of 14 367 individuals belonging to 38 species were collected. Diversity was significantly higher in the virgin forest than in the managed forest, while oposit pattern was detected for carabid beetle activity density. High activity density in the managed forest was primarly caused by extremely high abundance of Nebria dahlii. The nonmetric multidimensional scaling showed high similarity of carabid beetle assemblages between virgin and managed forests. The life-history traits analysis of species showed no significant difference between studied forests. However, analysis of morphological traits, especially body sizes, appeared to be appropriate tool for detecting changes in carabid beetle assamblages between studied forests. Furthermore, large sized carabid beetles prevail in the virgin forest. Therefore, the values of mean individual biomass were significantly higher in the virgin forest than in the managed forest. These differences imply on changes in carabid beetle assemblages between studied forests.
