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.
