Therefore, a better understanding of how land-use change affects ecological traits is crucial for efforts to sustain functional diversity. To this end we tested whether higher species richness or taxonomic distinctness generally leads to increased functional distinctness and whether intensive land use leads to functionally more narrow arthropod communities. We compiled species composition and trait data for 350 species of terrestrial arthropods (Araneae, Carabidae and Heteroptera) in different land-use types (forests, grasslands and arable fields) of low and high land-use intensity. We calculated the average functional and taxonomic distinctness and the rarified trait richness for each community. These measures reflect the range of traits, taxonomic relatedness and number of traits that are observed in local communities. Average functional distinctness only increased significantly with species richness in Carabidae communities. Functional distinctness increased significantly with taxonomic distinctness in communities of all analyzed taxa suggesting a high functional redundancy of taxonomically closely related species. Araneae and Heteroptera communities had the expected lower functional distinctness at sites with higher land-use intensity. More frequently disturbed land-use types such as managed grasslands or arable fields were characterized by species with smaller body sizes and higher dispersal abilities and communities with lower functional distinctness or trait richness. Simple recommendations about the conservation of functional distinctness of arthropod communities in the face of future land-use intensification and species loss are not possible. Our study shows that these relationships depend on the studied taxa and land-use type. However, for some arthropod groups functional distinctness is threatened by intensification and conversion from less to more frequently disturbed land-uses.}, language = {en} } @incollection{BirkhoferDiehlWoltersetal., author = {Birkhofer, Klaus and Diehl, Eva and Wolters, Volkmar and Smith, Henrik G.}, title = {Global metawebs of spider predation highlight consequences of land-use change for terrestrial predator-prey networks}, series = {Adaptive Food Webs - Stability and Transitions of Real and Model Ecosystems}, booktitle = {Adaptive Food Webs - Stability and Transitions of Real and Model Ecosystems}, publisher = {Cambridge University Press}, address = {Cambridge}, isbn = {978-1-107-18211-0}, pages = {193 -- 213}, language = {en} } @misc{BirkhoferGossnerDiekoetteretal., author = {Birkhofer, Klaus and Gossner, Martin M. and Diek{\"o}tter, Tim and Drees, Claudia and Ferlian, Olga and Maraun, Mark and Scheu, Stefan and Weisser, Wolfgang W. and Wolters, Volkmar and Wurst, Susanne and Zaitsev, Andrey S. and Smith, Henrik G.}, title = {Land-use type and intensity differentially filter traits in above- and below-ground arthropod communities}, series = {Journal of Animal Ecology}, volume = {86}, journal = {Journal of Animal Ecology}, number = {3}, issn = {1365-2656}, doi = {10.1111/1365-2656.12641}, pages = {511 -- 520}, language = {en} } @misc{MaderDiehlFiedleretal., author = {Mader, Viktoria and Diehl, Eva and Fiedler, Daniela and Thorn, Simon and Wolters, Volkmar and Birkhofer, Klaus}, title = {Trade-offs in arthropod conservation between productive and non-productive agri-environmental schemes along a landscape complexity gradient}, series = {Insect Conservation and Diversity}, volume = {10}, journal = {Insect Conservation and Diversity}, number = {3}, issn = {1752-4598}, doi = {10.1111/icad.12220}, pages = {236 -- 247}, language = {en} } @techreport{FeindtBahrsEngelsetal., author = {Feindt, Peter H. and Bahrs, Enno and Engels, Eve-Marie and Hamm, Ulrich and Herdegen, Matthias and Isselstein, Johannes and Schr{\"o}der, Stefan and W{\"a}tzold, Frank and Wolters, Volkmar}, title = {F{\"u}r eine Gemeinsame Agrarpolitik, die konsequent zum Erhalt der biologischen Vielfalt beitr{\"a}gt}, publisher = {Bundesanstalt f{\"u}r Landwirtschaft und Ern{\"a}hrung (BLE), Informations- und Koordinationszentrum f{\"u}r Biologische Vielfalt (IBV)}, address = {Bonn}, pages = {36}, language = {de} } @misc{MaderDiehlWoltersetal., author = {Mader, Viktoria and Diehl, Eva and Wolters, Volkmar and Birkhofer, Klaus}, title = {Agri-environmental schemes affect the trophic niche size and diet of common carabid species in agricultural landscapes}, series = {Ecological Entomology}, volume = {43}, journal = {Ecological Entomology}, number = {6}, issn = {1365-2311}, doi = {10.1111/een.12671}, pages = {823 -- 835}, abstract = {1. Carabids are abundant in agroecosystems and provide biocontrol services by feeding on weed seeds and pests. We compare the effects of two fundamentally different agri-environmental schemes (AES) on the numeric and trophic responses of four common carabid species: Anchomenus dorsalis, Poecilus cupreus, Pseudoophonus rufipes and Pterostichus melanarius. 2. In six cereal fields under organic farming and six sown flowering fields, 10 290 individuals of the four species were sampled to quantify their numeric response. The activity density of all species was higher in organically managed cereal fields compared to flowering fields. 3. We analysed naturally occurring stable isotope ratios of carbon and nitrogen in 138 carabid individuals to quantify isotopic niches and the diet contribution of soil- versus plant-based resources. Resources from the soil ('brown') energy channel were more important than resources from the plant ('green') energy channel in the diet of all species, particularly in P. melanarius. 4. Isotopic niches were larger for P. rufipes and P. melanarius in flowering fields than in organically managed cereal fields. Moreover, differences between AES types were observed in the diet contribution derived from both energy channels: A. dorsalis and P. cupreus incorporated higher proportions of plant-based resources in organically managed cereal fields compared to flowering fields. 5. Similar numeric, but different trophic responses suggest that AES type may alter arthropod food webs beyond simple changes in carabid densities. Such 'hidden' modifications in the resource utilisation of generalist predators deserve more attention to adequately evaluate the ecological consequences of AES.}, language = {en} } @misc{ZaitsevBirkhoferEkschmittetal., author = {Zaitsev, Andrey S. and Birkhofer, Klaus and Ekschmitt, Klemens and Wolters, Volkmar}, title = {Belowground Tritrophic Food Chain Modulates Soil Respiration in Grasslands}, series = {Pedosphere}, volume = {28}, journal = {Pedosphere}, number = {1}, issn = {1002-0160}, doi = {10.1016/S1002-0160(18)60008-6}, pages = {114 -- 123}, abstract = {Edaphic biota significantly affects several essential ecological functions such as C-storage, nutrient turnover, and productivity. However, it is not completely understood how belowground animal contribution to these functions changes in grasslands subject to different land use types. A microcosm experiment was carried out to test the effect of a tritrophic food chain on CO2 release from grassland soils. Soil was collected from three differently managed grassland systems (meadow, pasture, and mown pasture) located in three distinct German regions that cover a north-south gradient of approximately 500 km. The tritrophic food chain comprised natural edaphic microflora, nematodes, and predatory gamasid mites. The experimental design involved a full factorial combination of the presence and absence of nematodes and gamasid mites. Nematodes significantly increased the CO2 emissions in most treatments, but the extent of this effect varied with land use type. The fact that grazing by nematodes stimulated the metabolic activity of the edaphic microflora over a wide range of grassland soils highlighted the critical impact of the microfauna on ecosystem services associated with soil organic matter dynamics. Gamasids slightly amplified the effect of nematodes on microbial metabolic activity, but only in the pastures. This effect was most probably due to the control of nematode abundance. The fact that gamasid addition also augmented the impact of environmental conditions on nematode-induced modulation of soil respiration highlighted the need for including land use differences while evaluating soil fauna contribution to soil processes. To conclude, the differential response of the investigated tritrophic food chain to different grassland management systems suggests that adverse effects of land use intensification on important soil processes such as atmospheric C-release could potentially be reduced by using management methods that preserve essential features of the belowground food web.}, language = {en} } @techreport{FeindtWoltersBackesetal., author = {Feindt, Peter H. and Wolters, Volkmar and Backes, Gunter and Bahrs, Enno and Brandt, Horst and Engels, Eve-Marie and Engels, Johannes and Graner, Andreas and Hamm, Ulrich and Herdegen, Matthias and Isselstein, Johannes and Schr{\"o}der, Stefan and Tholen, Ernst and Wagner, Sven and W{\"a}tzold, Frank and Wolf, Heino}, title = {Schutz tiergenetischer Ressourcen im Tierseuchenfall - Vorschl{\"a}ge zum Schutz von Tierbest{\"a}nden in Nukleus- bzw.
