This study focuses on how agricultural land use affects the community composition, emergence and dispersal tendency of predatory arthropods. The arthropods were collected in emergence traps during the growing season (14 weeks) in a gradient of agricultural land uses from intensively managed sugar beet fields, over winter wheat fields, to less intensively managed grasslands. The emergence traps were equipped with one pitfall trap and a collecting bottle at the top. The distribution of the arthropods between these two collecting methods was assumed to represent their tendency to move out of the habitat. The grasslands had the highest numbers of spiders, while the winter wheat fields had the highest numbers of omnivorous rove beetles and macropterous predaceous ground beetles. The phenology of emergence differed between the land-use types, resulting in seasonal differences in community composition. The overall dispersal tendency of predatory arthropods was higher in crop fields than in grasslands. This study suggests that only a diverse mix of agricultural land uses will provide high levels of predators from different functional groups, throughout the growing season.}, language = {en} } @misc{BirkhoferRuschAnderssonetal., author = {Birkhofer, Klaus and Rusch, Adrien and Andersson, Georg K.

In our study, we investigated how the species composition and the potential interaction networks of herbivore and parasitoid communities in oilseed rape fields are affected by agricultural landscape characteristics. Insect communities of 26 winter oilseed rape fields in southern Sweden were captured in water traps over a continuous time span of 30 ± 2 days. In total, 31\% of the variation in the composition of herbivore host communities was explained by a combination of the surrounding oilseed rape area in the study year and the previous year and distance to the nearest forest. The oilseed rape area in the study year and distance to forest also explained 14\% of the variation in the composition of parasitoid communities. Distance to the nearest forest together with the area of oilseed rape in the previous year explained 45\% of the variation in asymmetry of interaction webs. These results indicate that several measures of landscape configuration are important both for the composition of host and parasitoid communities and also for the structure of interaction networks. Our results support the view that it is an appropriate strategy to cultivate oilseed rape in landscapes that are far away from forests, in order to minimize recolonization by pest species and at the same time to attract parasitoid species from the open landscape.}, language = {en} } @misc{KundelBodenhausenBrachtJorgensenetal., author = {Kundel, Dominika and Bodenhausen, Natacha and Bracht J{\o}rgensen, Helene and Truu, Jaak and Birkhofer, Klaus and Hedlund, Katarina and M{\"a}der, Paul and Fliessbach, Andreas}, title = {Effects of simulated drought on biological soil quality, microbial diversity and yields under long-term conventional and organic agriculture}, series = {FEMS Microbiology Ecology}, volume = {96}, journal = {FEMS Microbiology Ecology}, number = {12}, issn = {1574-6941}, doi = {doi: 10.1093/femsec/fiaa205}, pages = {12}, abstract = {Drought and agricultural management influence soil microorganisms with unknown consequences for the functioning ofagroecosystems. We simulated drought periods in organic (biodynamic) and conventional wheat fields and monitoredeffects on soil water content, microorganisms and crops. Above the wilting point, water content and microbial respirationwere higher under biodynamic than conventional farming. Highest bacterial and fungal abundances were found inbiodynamically managed soils, and distinct microbial communities characterised the farming systems. Most biological soilquality parameters and crop yields were only marginally affected by the experimental drought, except for arbuscularmycorrhizal fungi (AMF), which increased in abundance under the experimental drought in both farming systems. AMFwere further strongly promoted by biodynamic farming resulting in almost three times higher AMF abundance underexperimental drought in the biodynamic compared with the conventional farming system. Our data suggest an improvedwater storage capacity under biodynamic farming and confirms positive effects of biodynamic farming on biological soilquality. The interactive effects of the farming system and drought may further be investigated under more substantialdroughts. Given the importance of AMF for the plant's water supply, more in-depth studies on AMF may help to clarify theirrole for yields under conditions predicted by future climate scenarios.}, language = {en} }
