      abstract     = {This study aimed to measure the effect of plant diversity
                      on N uptake in grasslands and to assess the mechanisms
                      contributing to diversity effects.Annual N uptake into
                      above- and belowground organs and soil nitrate pools were
                      measured in the Jena experiment on a floodplain soil with
                      mixtures of 2-16 species and 1-4 functional groups, and
                      monocultures. In mixtures, the deviation of measured data
                      from data expected from monoculture performance was
                      calculated to assess the contribution of
                      complementarity/facilitation and selection.N uptake varied
                      from < 1 to 45 g N m(-2) yr(-1), and was higher in
                      grasslands with than without legumes. On average, N uptake
                      was higher in mixtures (21 +/- 1 g N m(-2) yr(-1)) than
                      monocultures (13 +/- 1 g N m(-2) yr(-1)), and increased with
                      species richness in mixtures. However, compared to N uptake
                      expected from biomass proportions of species in mixtures, N
                      uptake of mixtures was only slightly higher and a
                      significant surplus N uptake was confined to mixtures
                      containing legumes and non-legumes.In our study, high N
                      uptake of species rich mixtures was mainly due to dominance
                      of productive species and facilitation by legumes whereas
                      complementarity among non-legumes was of minor relevance.},
