      abstract     = {Increasing productivity of mixtures as compared to
                      monocultures has been reported from numerous experimental
                      studies, but so far the variable contribution of individual
                      species to higher mixture productivity in biodiversity
                      experiments is not well understood. To address this issue,
                      we quantified the productivity of 60 species in monocultures
                      and mixtures of varying species richness (2, 4, 8, 16, 60)
                      and functional group number and composition (1, 2, 3,4;
                      legumes, grasses, small herbs, tall herbs) and tested how
                      species properties are related to species performance in
                      mixtures in the third year after sowing. We analysed
                      monoculture biomass, plant biomass from separately grown
                      plant individuals (=estimate of plant growth rates), and the
                      monoculture resource-use characteristics canopy height and
                      structure (leaf area index) as indicators for light
                      acquisition, and soil nitrate concentration (=estimate of
                      depletion of plant available nitrogen) and biomass:N ratios
                      (=estimate of biomass produced per unit plant N) as
                      indicators for nitrogen acquisition and use. High
                      monoculture productivity was related to different
                      combinations of resource-use characteristics. The biomass of
                      a species and its proportional contribution to mixture
                      biomass correlated positively with species relative yields,
                      suggesting that highly productive mixture species were most
                      important for an overyielding of mixtures. Although
                      monoculture biomass was a significant predictor for species
                      performance in mixtures except for grasses, a combination of
                      monoculture biomass, plant growth rates and resource-use
                      traits associated with nutrient and light acquisition
                      explained non-legume species performance best. Legume
                      performance was best associated with their monoculture
                      biomass and traits associated with light acquisition. In
                      spite of the fact that high species performance in mixtures
                      was associated with a species' competitive ability as
                      represented by monoculture productivity, growth rates and
                      resource-use traits, our results suggest that species
                      uniqueness in resource acquisition strategies increases the
                      chance for niche differentiation among overyielding species.
