“…Open-habitat species with high dispersal power were significantly more abundant in natural edges than interiors, while became more similar in edges under anthropogenic interventions compared to their interiors. Contrary to this, the forest specialist species of limited dispersal power showed similar abundances in natural forest edges and interiors, but avoided edges influenced by agriculture or urbanisation (Magura & Lövei 2020b). In accordance with the history-based edge effect hypothesis (Magura et al 2017), our results clearly demonstrate, that the permeability (the filter function) of edges is essentially different depending on their history (maintaining processes) (Strayer et al 2003.…”

“…Therefore, in the present study, different habitat affinity could not explain the size-dependent permeability of natural edges. Interactions between the above life history (wing form) and ecological trait (habitat affinity) can be a meaningful indicator (Magura & Lövei 2020b) to test the size-dependent permeability of natural edges. The proportion of macropterous or dimorphic matrix (open-habitat and generalist) species was 64% for the small, 48% for the medium-sized, and 20% for the large species.…”

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.

“…For forest specialist species, edges maintained by natural processes are penetrable, allowing these species to enter and cross the edges. However, edges created by urbanization are impenetrable, blocking the emigration of forest specialists from the forest fragments, contributing to even higher isolation of these species [97,98]. Similarly, the abundance of predatory ground beetles was higher in natural edges than their forest interiors, while no similar pattern was detected in edges sustained by urbanization.…”

“…Management practices of urban habitats may alter the location and intensity of edge effects [96]. The abundance of forest specialist carabids was similar in edges maintained by natural processes and their interiors, while it was significantly lower in the edges than interiors of urban forest fragments [97,98]. The filtering function of variously maintained edges is fundamentally different.…”

Purpose of Review Urbanization is increasing worldwide, transforming environmental and habitat parameters, and causing adverse effects on organisms living in urban habitats. Urban studies on ground beetles are exponentially increasing and cover all levels of biological organization. Still, to date, there is no comprehensive paper reviewing the impacts of urbanization on ground beetles at different levels of biological organization. Recent Findings At the population level, urbanization induces changes in the morphological characters, including fluctuating asymmetry, physiological condition, behavioral characteristics, seasonal activity, population size, and genetic diversity in ground beetles. Different species groups (habitat specialists vs. generalists, large vs. small-sized species, poor vs. good dispersers, predators vs. herbivores) respond differently to urbanization. Community-level changes associated with urbanization include the abundance, taxonomic as well as functional diversity, community assembly mechanisms, composition, and body size distribution. At the ecosystem level, urbanization influences several ecosystem processes and functions related to ground beetles, but data are only available concerning the edge effect and predation. Summary Urbanization has a considerable effect at various levels of the biological organization on ground beetles living in urban habitats. However, results—especially at the population and community levels—show inconsistent patterns. This discrepancy may result from individual responses and different sensitivity of species to urbanization, suggesting the importance of individualistic and functional approach in future urban studies. To preserve a rich carabid diversity in urban areas, multi-scale greenspace planning and management schemes are needed; these will also ensure both the recreational and the diversity-preserving function of urban green spaces.

“…Magura (2017) and Roume et al (2011) found higher dispersal ability from forest species into open habitat than vice versa. However, permeability of forest edges by carabids is dependent on their history (Magura et al, 2017;Magura & Lövei, 2020). Although edges created through anthropogenic influence are penetrable for open habitat species, they are avoided by forest species (Magura & Lövei, 2020).…”

Increasing demand for biomass has led to an on-going intensification of fuel wood plantations with possible negative effects on open land biodiversity. Hence, ecologists increasingly call for measures that reduce those negative effects on associated biodiversity. However, our knowledge about the efficiency of such measures remains scarce. 2 We investigated the effects of gap implementation in short rotation coppices (SRCs) on carabid diversity and assemblage composition over 3 years, with pitfall traps in gaps, edges and interiors. In parallel, we quantified soil surface temperature, shrub-and herb cover. 3 Edges had the highest number of species and abundances per trap, whereas rarefied species richness was significantly lower in short rotation coppice interiors than in other habitat types. Carabid community composition differed significantly between habitat types. The main environmental drivers were temperature for number of species and abundance and shrub cover for rarefied species richness. 4 We found significantly higher rarefied species richness in gaps compared with interiors. Hence, we argue that gap implementation benefits overall diversity in short rotation coppices. Furthermore, the differences in species community composition between habitat types through increased species turnover support carabid diversity in short rotation coppices. These positive effects were largely attributed to microclimate conditions. However, to maintain positive effects, continuous management of herb layer might be necessary.
