Vegetation cover and grasslands in the vicinity accelerate development of carabid beetle assemblages on restored landfill sites

Abstract

28There is increasing evidence that rare and scarce carabid species of conservation On the landfill sites, generalist species were common, while no nationally rare or scarce 38 species were found. Neither species richness nor diversity of carabid species was found

Carabid community structure in northern China grassland ecosystems: Effects of local habitat on species richness, species composition and functional diversity

“…Vegetation characteristics are positively related to carabid species richness at regional scale (as species richness) and in the typical steppe (as PC), but not in the desert and meadow steppes. Rahman et al (2015) hypothesized that vegetation cover might accelerate the establishment of carabid communities because it provides living space and modifies the microclimate to create a heterogeneous and stratified microenvironment supporting different carabid species. The influence of plant diversity on carabid richness at the regional level, which includes a variety of habitat types with different communities, is consistent with previous studies reporting that a higher plant species richness implies more diverse food resources, thus allowing the presence of species with different feeding preferences (Byers et al, 2000; Brose, 2003).…”

Influence of Climate and Local Habitat Characteristics on Carabid Beetle Abundance and Diversity in Northern Chinese Steppes

“…This inconsistency may be due to differences in the ecosystems. Vegetation cover might promote carabid diversity by creating a heterogeneous and stratified microenvironment supporting different species [74]. While this role can be very important in environments dominated by herbs, such as the typical and meadow steppes, it may be less relevant in the desert steppe (where vegetation is too sparse and its structure too simple and homogeneous to have detectable influences on carabid diversity) or in forests (where the vegetation structure is dominated by trees, not by herbs).…”

Effect of soil conditions and landscape factors on macro-snail communities in newly created grasslands of restored landfill sites in the UK

“…In order to provide a comparison, nine reference sites (hereafter RF) were selected which were the closest recognized protected grassland sites for their nature conservation value, being designated as either Local Nature Reserves (LNRs) or Sites of Special Scientific Interest (SSSIs) for their local or national special natural interest respectively. The RF sites were spatially close enough (mean distance = 4.5 ± 3.5 km, range = 1.3-11.8 km) to the LF sites so that they experience similar physiography, climate, soil and land use history (see details in Rahman et al 2015). Six of the restored landfill sites were managed by mowing during the late summer and three sites had no mowing or grazing regime (Table 1).…”

“…Land snail populations are considered to be relatively stable (Lydeard et al ), however, the abundance of some grassland snail species may have changed mainly due to intensive management practices coupled with habitat loss (Kerney 1999;Martin and Sommer 2004a;Stoll et al 2009). Many invertebrate species of conservation importance are established on brownfield sites such as landfill (Judd and Mason 1995;Rahman et al 2015;Tarrant et al 2013). Therefore, the process of habitat restoration could be important for the enhancement of other invertebrate species such as land snails which may have been declined locally or regionally such as Arianta arbustorum and Candidula gigaxii (Seddon et al 2014).…”
