Here, we adopted a hierarchical approach to test the contribution of region, landscape heterogeneity, local management (organic vs. conventional) and location within field (edge vs. centre) to the species richness and abundance of spiders in cereals.Location Three regions of western and central Germany: Leine Bergland, Soester Boerde, and Lahn-Dill Bergland.Methods Forty-two paired organic and conventional winter wheat fields were compared. Field pairs were located in areas ranging from structurally simple to structurally complex landscapes. In May and June 2003, spiders were sampled using pitfall traps. Linear mixed models were used to determine the relationship of spider diversity and abundance with regional spatial factors and landscape heterogeneity within a 500-m radius, as well as with local management and within-field location.Results Within-field location of the traps and landscape heterogeneity were the best predictors of species richness: more species were found in field edges and in heterogeneous landscapes. Region and local management had no effect on species richness. Activity density was higher in field edges and differed among regions.Main conclusions The diversity of farmland spiders was influenced by differences at two of the spatial scales (edge vs. centre, simple vs. complex landscapes), but not at the two others (field management, region), emphasizing the importance of analyses at a variety of spatial scales for an adequate explanation of patterns in biodiversity. Our study suggests that promoting heterogeneity in land use at landscape scales is one of the keys to promoting spider diversity in agroecosystems."],["dc.identifier.doi","10.1111/j.1365-2699.2005.01367.x"],["dc.identifier.gro","3149799"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6497"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","0305-0270"],["dc.subject","Agroecosystem; Araneae; biodiversity; biological control; cereals; landscape composition; organic farming; regional variation; scale effects"],["dc.title","Spider diversity in cereal fields: comparing factors at local, landscape and regional scales"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

This process of habitat fragmentation has been perceived as “the principle threat to most species in the temperate zone” (Wilcove et al., 1986) or “the single greatest threat to biological diversity” (Noss, 1991). Although habitat fragmentation occurs naturally, it is mostly caused by the expansion and intensification of anthropogenic land use (Burgess and Sharpe, 1981). For example, in the Australian wheat belt region 93% of the native vegetation has been cleared, mostly during the last 50 years (Saunders et al., 1993). Estimating the current effects of fragmentation on species diversity is often difficult (Margules et al., 1994), and most investigations have studied the effects a posteriori (Villard and Taylor, 1994). As mentioned by Didham et al. (1998), little attention has been paid to alteration in the trophic structure of communities due to habitat fragmentation, because most studies have focused on single species or several species within one trophic level. Since habitat fragmentation does not affect all species equally, results from systems with such reduced levels of complexity cannot be extrapolated to explain responses of food-web or community interactions."],["dc.identifier.doi","10.1007/978-94-017-1913-1_4"],["dc.identifier.gro","3149918"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6629"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.publisher","Springer"],["dc.publisher.place","Dordrecht"],["dc.relation.doi","10.1007/978-94-017-1913-1"],["dc.relation.eisbn","978-94-017-1913-1"],["dc.relation.isbn","978-90-481-4027-5"],["dc.relation.ispartof","Interchanges of Insects between Agricultural and Surrounding Landscapes"],["dc.title","Effects of Habitat Fragmentation on Plant-Insect Communities"],["dc.type","book_chapter"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Management effects were found to strongly depend on feeding group. While the activity-density of predators was higher in the conventional fields, both activity-density and species richness of detritivores were higher in the organic fields. Activity-density and species richness of detritivores were positively correlated to crop yield in the conventional but not in the organic fields. Unexpectedly, species richness as high as in the less productive organic fields was thus found in intensified conventional systems. No significant effects of landscape context could be found on activity-density or species richness of the different feeding groups. More species were caught near the field edge than in the middle, showing the importance of spill-over from field boundaries into arable crops for diversity. In conclusion, separation of species into feeding groups revealed patterns that have not been shown before. Decomposer diversity (but not that of predators and fungivores) was higher in organic fields, but reached similar levels in high-yielding conventional fields.

Vegetation complexity (plant species richness, vegetation height, vegetation heterogeneity) was significantly higher on ungrazed grasslands compared to pastures but did not differ between intensively and extensively grazed pastures. However, insect species richness was higher on extensively than on intensively grazed pastures, established by suction sampling of four insect taxa (Auchenorrhyncha, Heteroptera, Coleoptera, Hymenoptera Parasitica). This may be due to intensive grazing disrupting plant–insect associations as predicted by a “trophic-level” hypothesis. Local persistence and small-scale recolonization of insects on plants appeared to be difficult in the highly disturbed environment of intensive grazing. Insect diversity increased across the four treatments in the following order: intensively grazed
