      abstract     = {The rate at which a plant species is attacked by
                      invertebrate herbivores has been hypothesized to depend on
                      plant species richness, yet empirical evidence is scarce.
                      Current theory predicts higher herbivore damage in
                      monocultures than in species-rich mixtures. We quantified
                      herbivore damage by insects and molluscs to plants in
                      experimental plots established in 2002 from a species pool
                      of 60 species of Central European Arrhenatherum grasslands.
                      Plots differed in plant species richness (1, 2, 4, 8, 16, 60
                      species), number of functional groups (1, 2, 3, 4),
                      functional group and species composition. We estimated
                      herbivore damage by insects and molluscs at the level of
                      transplanted plant individuals ("phytometer" species
                      Plantago lanceolata, Trifolium pratense, Rumex acetosa) and
                      of the entire plant community during 2003 and 2004. In
                      contrast to previous studies, our design allows specific
                      predictions about the relative contributions of functional
                      diversity, plant functional identity, and species richness
                      in relation to herbivory. Additionally, the phytometer
                      approach is new to biodiversity-herbivory studies, allowing
                      estimates of species-specific herbivory rates within the
                      larger biodiversity-ecosystem functioning context. Herbivory
                      in phytometers and experimental communities tended to
                      increase with plant species richness and the number of plant
                      functional groups, but the effects were rarely significant.
                      Herbivory in phytometers was in some cases positively
                      correlated with community biomass or leaf area index. The
                      most important factor influencing invertebrate herbivory was
                      the presence of particular plant functional groups. Legume
                      (grass) presence strongly increased (decreased) herbivory at
                      the community level. The opposite pattern was found for
                      herbivory in T. pratense phytometers. We conclude that (1)
                      plant species richness is much less important than
                      previously thought and (2) plant functional identity is a
                      much better predictor of invertebrate herbivory in temperate
                      grassland ecosystems.},
