Effects of mowing frequency on grassland flora and fauna: implications for the conservation of semi-natural grasslands in Europe
To maintain the high biodiversity and preserve the conservation value of semi-natural grasslands, management like grazing or mowing is necessary. Given the limited resources available for management, and few remaining areas, the best management method and intensity should be used. However, the evaluation and comparison of effects of different management intensities on a larger scale is often challenging, as most studies have a limited scope (e.g. only investigating effects in one grassland or for one type of organism). In view of this, we used meta-analysis methods to explore effects of different mowing intensities on biodiversity on a European scale, to reach more robust conclusions. We in…
Swedish monitoring data reveal negative effect of neo-nicotinoids on bumblebee abundance
Neo-nicotinioids are used as insecticides in a variety of crops, e.g. as seed-coating, but have also been found lethal to pollinating insects. In 2013, the European Union introduced a moratorium on some of these compounds. At the same time, the Swedish monitoring program NILS (National Inventory of Landscapes in Sweden) had completed its first round and today a second round has been completed. Thus, it is possible to analyze the effect of the moratorium on monitoring data on bumblebees in N=419 sites in southern Sweden. The presence of neo-nicotiniods was assessed using the official records of the type of crop grown on a field (Blockdatabasen), maintained by the Swedish board of Agriculture…
