Cím:The type of forest edge governs the spatial distribution of different-sized ground beetles / Magura Tibor, Lövei Gábor L.
Dátum:2020
ISSN:1217-8837
Megjegyzések:Worldwide human-induced habitat fragmentation intensifies the emergence of forest edges. In addition to these edges, there are edges evolved by natural processes. Edge-maintaining processes (natural vs. anthropogenic) fundamentally determine edge responses, and thus edge functions. Species with various traits show fundamentally different edge response, therefore the trait-based approach is essential in edge studies. We evaluated the edge effect on the body size of ground beetles in forest edges with various maintaining processes. Our results, based on 30 published papers and 221 species, showed that natural forest edges were impenetrable for small species, preventing their dispersal into the forest interiors, while both the medium and the large species penetrated across these edges and dispersed into the forest interiors. Anthropogenic edges maintained by continued human disturbance (agriculture, forestry, urbanisation) were permeable for ground beetles of all size, allowing them to invade the forest interiors. Overwintering type (overwintering as adults or as larvae) was associated with body size, since almost two-thirds of the small species, while slightly more than a third of both the medium and the large species were adult overwintering. Based on this, size-dependent permeability of natural edges may be related to overwintering type, which basically determines species tolerance to human disturbance.

Cím:Spatial distribution of carabids along grass-forest transects / T. Magura, B. Tóthmérész, T. Molnár
Dátum:2000
ISSN:1217-8837
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.

Cím:Various edge response of ground beetles in edges under natural versus anthropogenic influence : a meta-analysis using life-history traits / Tibor Magura, Gábor L. Lövei, Béla Tóthmérész
Dátum:2019
ISSN:1217-8837
Megjegyzések:Edges are on the increase world-wide due to increasing fragmentation and loss of natural habitats. After formation, edges are maintained by various processes (natural vs. continued anthropogenic interventions: forestry, agriculture, urbanization) which influence the reaction of individual species to edge effects (history-based edge effect hypothesis), and this will be reflected in the diversity of assemblages. Diversity, however, is not the most appropriate indicator of the edge effect because species with different traits may respond differently to the edges. To further articulate the history-based edge effect hypothesis, we evaluated the edge effect on one of the most commonly used life-history traits, the feeding habit of ground beetles in forest edges. A meta-analysis based on 28 publications and 422 comparisons showed that natural vs. continued anthropogenic interventions as edge-maintaining processes reflected at the trait level. Abundance of herbivorous, omnivorous, and predatory ground beetle species were all higher in the natural edges than in the forest interiors, while no similar pattern occurred in edges with continued anthropogenic influence. These results suggest that structural and environmental changes at edges sustained by repeated anthropogenic influence adversely influencing ecosystem functions, with negative effects on ecosystem services like pest or weed control.
