Cím:	Spatial distribution of carabids along grass-forest transects / T. Magura, B. Tóthmérész, T. Molnár

Megjegyzések:	Spatial distribution of ground-beetles and associations between carabids and environmental variables were studied in grass-forest transects in the Aggtelek National Park in Hungary. The carabid assemblages of the grass, the forest edge and the forest interior can be separated from each other by principal coordinates analysis, suggesting that all habitats have a characteristic and distinct species composition. The collected carabid species can be divided into five groups by indicator species analysis: (1) habitat generalists, (2) forest generalists, (3) species of the grass, (4) forest edge species, and (5) forest specialists. Distributions of the eighteen most frequent carabids were generally aggregated. There were significant correlations between the carabid abundance and the following abiotic factors: relative cover of the leaf litter, the herbs, the shrubs, and the canopy layer. Biotic factors, like the abundance of the carabids' prey, and the occurrence of other carabids cr,ere also correlated significantly with the distribution of particular species at the studied spatial scale. For the eighteen most frequent species we found 7 significant positive and 4 significant negative correlations of the abundance patterns. For two species (Molops piceus (PANZER, 1793) and Pterostichus burmeiseri HEER, 1841), which are of similar size, spatial pattern and seasonal activity, we found significant negative interaction suggesting interspecific competition between them. The results stress the importance of an integration of biotic and abiotic factors in carabid ecology, and also provide an empirical approach for understanding spatial distribution of carabids.
