Landscape and habitat filters jointly drive richness and abundance ofspecialist plants in terrestrial grassland islands
Land use changes have resulted in the loss and isolation of semi-natural habitats worldwide. In intensively used agricultural landscapes the remnants of natural flora only persist in small habitat islands embedded in a hostile matrix (Deák et al. 2016a). Species composition of small habitat islands is substantially influenced by habitat and landscape filters through persistence and dispersal traits of plant species. Due the interaction of factors acting in different spatial scales, vegetation of habitats islands can be evaluated by a complex approach considering multiple spatial scales. We sampled grassland specialist plant species, local environmental factors (habitat filter) and the lands…
Various responses of ground beetles in natural versus anthropogenic edges
Worldwide fragmentation and loss of natural habitats increase the occurrence of habitat edges that are transitional zones between adjoining ecosystems or habitats. Once created, edges are distinguishable by their maintaining processes: natural vs. continued anthropogenic interventions (forestry, agriculture, urbanization). According to our history-based edge effect hypothesis (Magura et al. 2017), dissimilar edge histories are reflected in the diversity and assemblage composition of their inhabitants. Testing this hypothesis, we evaluated available information on ground beetles (Coleoptera: Carabidae) in forest edges. A meta-analysis based on 39 publications showed that the diversity-enhanc…
