“…In our study, both the number of threatened carabid beetle and spider species were highest in grey dunes. Grey dunes therefore seem to be of crucial importance for the maintenance of endangered xerothermic species (Bonte et al 2003Maes and Bonte 2006). This is especially true, since three carabid beetle (Amara infima, Amara tibialis, Harpalus solitaris) and four spider (Aelurillus v-insignitus, Alopecosa schmidti, Ozyptila scabricula, Talavera aequipes) indicator species are listed as threatened.…”

We analyzed the impacts of succession and grass encroachment on carabid beetle and spider assemblages in a coastal heathland. Further, indicator species for different successional stages (grey dunes, dwarf-shrub heath, grassy heath, heath with shrubs, birch forest) were identified, and their relations to habitat parameters were analyzed. The study was conducted on the Baltic island of Hiddensee, Germany. Ground-dwelling arthropods were sampled using pitfall traps along a successional gradient containing five stages. Ordination by nonmetric multidimensional scaling (NMDS) and analysis of similarities (ANOSIM) revealed a clear separation of species composition among the successional stages. Both in carabid beetles and spiders, most indicator species were obtained in the youngest stage (grey dunes) and fewest in the intermediate stages (grassy heath, heath with shrubs). Also the proportion of endangered species was highest in grey dunes. Based on our results, conservation management of coastal heathlands should preserve a mosaic of different successional stages with a clear preference on younger stages (grey dunes and dwarf-shrub heath).

“…Increase of grazing pressure can however have adverse effects on reptiles (Edgar et al 2010) and other fauna of nutrient-poor grasslands, as also shown for snails (Boschi and Baur 2007). Management of dune areas should aim at reversing this encroachment and restoring habitat heterogeneity at multiple scales, ranging from local sandy patches, for a species as the blue-winged grasshopper Oedipoda caerulescens, to a mosaic of different vegetation patches for butterflies as the grayling Hipparchia semele (Maes and Bonte 2006) and insectivorous birds as the red-backed shrike Lanius collurio (Van Duinen et al 2004). The key large scale management tool to achieve these goals is a sustainable reactivation of aeolian dynamics.…”

“…This process of grass and shrub encroachment is mainly caused by increased atmospheric nitrogen deposition (Jones et al 2004;Kooijman et al 1998), decreased intensity of grazing by rabbits after plagues of myxomatose and RVHD (Rabbit Viral Haemorrhagic Disease; Drees and Olff 2001;Ranwell 1963) and changes in land use practice (loss of marram harvest and agricultural use) (Provoost et al 2009). The habitat degradation is manifested as a decrease and loss of open sand, early successional stages, small herbaceous plants and lichens, with concomitant loss of variation in microclimatic conditions (Maes and Bonte 2006;Stoutjesdijk and Barkman 1992).…”

The effects of shifting vegetation mosaics on habitat suitability for coastal dune fauna—a case study on sand lizards (Lacerta agilis)

et al. 2011

Encroachment of tall grasses and shrubs in coastal dunes has resulted in loss of vegetation heterogeneity. This is expected to have negative effects on animal diversity. To counteract encroachment and develop structural heterogeneity grazing is a widely used management practice. Here, we aim to functionally interpret changes in vegetation composition and configuration following grazing management on habitat suitability for sand lizards. Aerial photographs taken over a period of 16 years were used to quantify changes in vegetation composition. A GISbased method was developed to calculate habitat suitability for sand lizards in a spatially explicit manner, encompassing differences in vegetation structure and patch size.

“…However, distribution patterns of different taxonomic groups display varying levels of congruence (Prendergast et al 1993;Reid 1998;Pawar et al 2007). This would justify the use of a multi-taxon approach to more accurately represent the country's ecological diversity (Carey et al 1995;Maes and Bonte 2007;Diffendorfer et al 2007). Therefore, this paper concentrates on five less-studied taxonomic groups to enable the identification of areas of biogeographical interest for these groups.…”

Defining hotspots of characteristic species for multiple taxonomic groups in the Netherlands

et al. 2010

Biogeographical zonation based on single taxa poses major limitations on planning for nature conservation. This paper identifies biogeographical patterns of multiple taxa in the Netherlands, where no endemics are present at species level, on the basis of characteristic species. We used occurrence data on five species groups in order to identify spatially coherent, ecologically important regions. TWINSPAN was used to cluster grid squares according to similarity in species composition for each taxonomic group. Species that are characteristic of each of the clusters were identified using a preference index, and corresponding clusters among the taxonomic groups were identified with Kappa statistics. Regions containing characteristic species for several taxonomic groups were defined as 'hotspots'. Stepwise discriminant analysis was then used to characterize these hotspots according to differences in environmental conditions. The analysis yielded five regions that are clearly distinct in terms of species composition for individual taxonomic groups. Each region is characterized by a set of unique species that occur in the zonation of at least two of the taxonomic groups. Stepwise discriminant analysis revealed significant environmental differences among these regions. The concept of hotspots as operationalized in this study can make nature conservation planning more efficient. In combination, the hotspots 123Biodivers Conserv (2010) 19:2517-2536 DOI 10.1007 defined here comprise the majority of the species occurring in the Netherlands for the studied groups. Therefore, this regionalization should be taken into account when prioritizing nature conservation efforts.
