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.

Evidence is provided that niche complementarity can strongly increase productivity in grasslands, although the communities contained only grasses and forbs.

- Environmental Science

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.

Above-ground resource use increases with plant species richness in experimental grassland ecosystems
- Environmental Science
- 2000
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.

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.
Mechanisms of positive biodiversity–production relationships: insights provided by δ13C analysis in experimental Mediterranean grassland plots
- Environmental Science
- 2001
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.
Community maturity, species saturation and the variant diversity-productivity relationships in grasslands.
- Environmental ScienceEcology letters
- 2006
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.

The results suggest that mixed seagrass meadows play an important role for ecosystem functioning and thus contribute to the provision of goods and services in coastal areas.

The data show that it is difficult to extrapolate results from experimental studies to semi-natural ecosystems, although there is a need to investigate natural ecosystems to fully understand the relationship of biodiversity and ecosystem functioning.
Species richness, temporal variability and resistance of biomass production in a Mediterranean grassland
- Environmental Science
- 2005
It is demonstrated for the first time that the relative strength of overyielding remained constant during an exceptional natural environmental perturbation, supporting previous findings of a positive relationship between diversity and productivity and between Diversity and the temporal stability of production, but of no effect of diversity on the resistance to perturbations.

- Environmental Science

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.

A mechanistic model of a spatially structured ecosystem in which plants compete for a limiting soil nutrient shows that plant species richness does not necessarily enhance ecosystem processes, but it identifies two types of factors that could generate such an effect: complementarity among species in the space they occupy below ground and positive correlation between mean resource-use intensity and diversity.
