    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Philippe Simon; [2023]
    Keywords : Ley production; Nitrogen fixation; Pollination ecology;

    Abstract : The population and diversity of pollinating insects in Europe are declining, partly due to lossof habitat. In agricultural landscapes, farming practices with more intensified land use haveincreased. In Swedish agricultural habitats, most ley production is dominated by grass and red clover (Trifolium pratense). READ MORE
