  abstract  = {Bat activity is often concentrated near linear and edge landscape structures such as hedgerows, but information about seasonal and species-specific bat activity near hedges is scarce despite their abundance in the cultural landscapes of central Europe. Exact knowledge on animals' habitat use, however, is key to effective landscape planning to avoid human-wildlife-conflicts, such as the construction of wind turbines in areas with high bat activity that may result in bat fatalities. We measured bat activity in relation to distance to hedgerows in an agricultural landscape in northeastern Germany. We recorded bat echolocation calls at ground level at 0, 50, 100 and 200 m distances from hedges at five sites during three nights in spring (April to June) and three nights in summer (July to October) at each site. For all bat species we found the overall activity to be similar between seasons, with the highest activity near the hedges, but with considerable variation in species-specific spatial activity patterns between spring and summer. While the genus Myotis and Pipistrellus pipistrellus were mostly active close to the hedges at a similar intensity over the entire study period (i.e. 84\% and 86\% of all bat passes, respectively), Nyctalus noctula and Pipistrellus nathusii showed generally less pronounced concentration of activity near the hedges, and increased activity away from the hedges in summer. Similarly, Pipistrellus pygmaeus showed decreased activity away from the hedges during both seasons, but with reduced activity near the hedges in summer. The observed behavioural changes in activity in relation to distance to hedgerows are likely due to migration or the bats foraging for different prey between seasons. Our findings are highly relevant for landscape planning and distance recommendations for the construction of wind turbines linked to their potential threat for bats.},

  abstract  = {Agricultural practice has led to landscape simplification and biodiversity decline, yet recently, energy-producing infrastructures, such as wind turbines, have been added to these simplified agroecosystems, turning them into multi-functional energy-agroecosystems. Here, we studied the trophic interactions of bats killed at wind turbines using a DNA metabarcoding approach to shed light on how turbine-related bat fatalities may possibly affect local habitats. Specifically, we identified insect DNA in the stomachs of common noctule bats (Nyctalus noctula) killed by wind turbines in Germany to infer in which habitats these bats hunted. Common noctule bats consumed a wide variety of insects from different habitats, ranging from aquatic to terrestrial ecosystems (e.g., wetlands, farmland, forests, and grasslands). Agricultural and silvicultural pest insects made up about 20\% of insect species consumed by the studied bats. Our study suggests that the potential damage of wind energy production goes beyond the loss of bats and the decline of bat populations. Bat fatalities at wind turbines may lead to the loss of trophic interactions and ecosystem services provided by bats, which may add to the functional simplification and impaired crop production, respectively, in multi-functional ecosystems.},
