      abstract     = {We investigated effects of plant species richness in
                      experimental grassland plots on annual above- and
                      belowground biomass production estimated from repeated
                      harvests and ingrowth cores, respectively. Aboveground and
                      total biomass production increased with increasing plant
                      species richness while belowground production remained
                      constant. Root to shoot biomass production ratios (R/S) in
                      mixtures were lower than expected from monoculture
                      performance of the species present in the mixtures, showing
                      that interactions among species led to reduced biomass
                      partitioning to belowground organs. This change in
                      partitioning to belowground organs was not confined to
                      mixtures with legumes, but also measured in mixtures without
                      legumes, and correlated with aboveground overyielding in
                      mixtures. It is suggested that species-rich communities
                      invest less in belowground biomass than do monocultures to
                      extract soil resources, thus leading to increased investment
                      into aboveground organs and overyielding.},
