Edge effect on carabids (Coleoptera: Carabidae) in beech forest - grassland transects in the Zemplén Mountains in Hungary

Research output: Contribution to journalArticle

Abstract

Abundance and species richness of ground beetles were studied along beech forest - forest edge - grassland transects in the Zemplén Mountains, Northern Hungary using pitfall traps. Ground beetle assemblages in the forest interior, forest edge and grassland were separated from each other by ordination based on abundances using the Bray-Curtis similarity coefficient. The scalable Rényi diversity ordering showed that the carabid assemblage of the grassland was the most diverse, while the forest edge was less diverse than the grassland. The least diverse was the forest assemblage. Overall species richness was identical in the grassland and in the forest edge. The number of forest species was significantly higher in the edge than in the grassland and forest. The number of generalist species was highest in the grassland and decreased towards the forest. The overall abundance was highest in the edge. The number of individuals of forest species was highest in the forest and decreased toward the grassland. The abundance of generalist species was significantly higher in the edge than in the grassland and forest. Character species analysis (IndVal) detected five groups of species: species of all habitats, grassland-associated species, species of grassland and edge, edge-associated species, and forest-associated species.
