At eight European field sites, the impact of loss of plant diversity on primary productivity was simulated by synthesizing grassland communities with different numbers of plant species. [...] Key Result Results differed in detail at each location, but there was an overall log-linear reduction of average aboveground biomass with loss of species. For a given number of species, communities with fewer functional groups were less productive.Expand

Diversity and Productivity in a Long-Term Grassland Experiment
TLDR
These results help resolve debate over biodiversity and ecosystem functioning, show effects at higher than expected diversity levels, and demonstrate, for these ecosystems, that even the best-chosen monocultures cannot achieve greater productivity or carbon stores than higher-diversity sites. Expand
Positive effects of plant species diversity on productivity in the absence of legumes
TLDR
Evidence is provided that niche complementarity can strongly increase productivity in grasslands, although the communities contained only grasses and forbs. Expand
ECOSYSTEM EFFECTS OF BIODIVERSITY MANIPULATIONS IN EUROPEAN GRASSLANDS
TLDR
Results from a multisite analysis of the relationship between plant diversity and ecosystem functioning within the European BIODEPTH network of plant-diversity manipulation experiments largely reinforce the previous results, and those from comparable biodiversity experiments, and extend the generality of diversity–ecosystem functioning relationships to multiple sites, years, and processes. Expand
Productivity and complementarity in grassland microcosms of varying diversity
TLDR
A framework to explain the relationship between species richness and productivity in terrestrial plant communities is developed and suggests the existence of a selection effect that involves species that are highly productive in mixtures, rather than in monoculture. Expand
Relationships between biodiversity and production in grasslands at local and regional scales.
1. Experimental manipulations of plant species diversity in unfertilised prairies and meadows has revealed that increasing diversity often leads to increased productivity (range of observedExpand
Tree species diversity and ecosystem function: Can tropical multi-species plantations generate greater productivity?
TLDR
Results from the humid tropics of Australia demonstrate that diverse plantations can achieve greater productivity than monocultures and suggest that significant productivity and ecological gains could be made if multi-species plantations are more broadly pursued. Expand
Above-ground resource use increases with plant species richness in experimental grassland ecosystems
TLDR
It is shown that with increasing diversity, mixtures perform better than the best monoculture, a strong indication that part of the positive effect of diversity on biomass production is driven by complementary resource use. Expand
Plant species richness and functional composition drive overyielding in a six-year grassland experiment.
TLDR
It is concluded that transgressive overyielding between functional groups and species richness effects within functional groups caused the positive biodiversity effects on aboveground community biomass in the large-scale biodiversity experiment near Jena, Germany. Expand
Mechanisms of positive biodiversity–production relationships: insights provided by δ13C analysis in experimental Mediterranean grassland plots
TLDR
The role of water use in a Mediterranean grassland was investigated, and a positive relationship was observed between plant species richness and productivity, suggesting complementarity or facilitation may be the mechanism responsible for the positive relationship between plant diversity and ecosystem processes. Expand
Community maturity, species saturation and the variant diversity-productivity relationships in grasslands.
TLDR
Community richness was enhanced by seeding additional species but productivity was not, and optimal diversity changed among sites and as the community developed, the findings shed new light on ecosystem functioning of biodiversity under different conditions and have important implications for restoration.

Biodiversity and plant productivity in a model assemblage of plant species
TLDR
Productivity as a function of biotic diversity was examined and showed that species-poor assemblages had wider ranges of possible productivities than more diverse assemblage. Expand
THE ROLE OF COMPLEMENTARITY AND COMPETITION IN ECOSYSTEM RESPONSES TO VARIATION IN PLANT DIVERSITY
TLDR
Results show that composition can be at least as important as richness as richness (the number of species present) in effects on ecosystem processes; competition during critical parts of the growing season may prevent absolute increases in net primary production with increasing diversity, despite complementary resource use at other times of the year. Expand
The Effects of Plant Composition and Diversity on Ecosystem Processes
TLDR
It is possible to identify and differentiate among potential mechanisms underlying patterns of ecosystem response to variation in plant diversity, with implications for resource management. Expand

TLDR
Three simple models of interspecific competitive interactions in communities containing various numbers of randomly chosen species predict that, on average, productivity increases asymptotically with the original biodiversity of a community and show that both species identity and biodiversity simultaneously influence ecosystem functioning.

Effects of plant composition and diversity on nutrient cycling
TLDR
An index of “relative resource use” that incorporates the effects of plants on pool sizes of several depletable soil resources: inorganic nitrogen in all seasons, availability of available nutrient pool sizes, and leaching losses is used. Expand
The Influence of Functional Diversity and Composition on Ecosystem Processes
TLDR
Functional composition and functional diversity were the principal factors explaining plant productivity, plant percent nitrogen, plant total nitrogen, and light penetration in grassland plots. Expand
A problem for biodiversity-productivity studies: how to compare the productivity of multispecific plant mixtures to that of monocultures?
TLDR
It is argued that a clear test of whether the productivity of communities increases with species richness requires that all species present in the multispecies assemblages also be grown in monocultures under the same environmental conditions. Expand
Species loss and ecosystem functioning : effects of species identity and community composition
TLDR
The functional identity of a species predicted the type of impact its loss had on productivity, but not on nitrogen retention, and the magnitude and direction of change in ecosystem functioning with declining diversity depended on the identity of the species deleted and the composition of the community from which it was deleted.

Biotic diversity and ecosystem processes: using the Ecotron to study a complex relationship
TLDR
It is shown how mesocosm studies conducted in the Ecotron, a controlled environmental facility, provide insights into this complex issue of species richness observable in most ecosystems. Expand

Island area is frequently a major determinant of the species composition of biological communities; community structure, in turn, often has important effects on ecosystem-level properties. FiftyExpand
