Forest edge and diversity carabids along forest-grassland transects
Diversity relationships of carabids in forest edges and the neighbouring forest interior and the surrounding grassland are studied. Samples were taken along three replicated forest-grassland transects using pitfall traps in the Aggtelek National Park in Hungary during 2 years. The study revealed significant edge effect on the carabids. The Shannon diversity of carabids were significantly higher in the forest edge and the grassland than in the forest interior. Carabids of the forest interior, forest edge and grassland can be separated from each other by ordinations, both on the species composition and abundance, suggesting that all three habitats have a distinct species assemblage. Moreover, indicator species analysis detected significant edge associated species; based on the specificity and fidelity of the carabids we have distinguished five groups of species: habitat generalists, grassland-associated species, forest generalists, forest specialists, and edge-associated species
