2000, Fargione and Tilman 2005, Mueller et al. This potentially strong asymmetric competition was associated with overall higher biomass production with increasing diversity in our study. 2018). We present the results of a meta‐analysis of 21 data sets from experimental species‐richness gradients in grasslands. 4; Appendix S1: Table S6, inverse CV, all biomass model, rz = 0.069, P = 0.342).

(1) Does species richness enhance biomass production or community resource uptake across sites? Intraspecific competition denotes competition for resources by individuals of the same species. In contrast to our prediction (Fig. 2013, Williams et al. Resource uptake rates vary within plant root systems and may therefore deviate from biomass distributions (Hodge 2004, Chen et al. 1996, Reich et al. 2015 for water uptake at smaller increments). 2014, Barry et al. Resource partitioning is the division of limited resources by species to help avoid competition in an ecological niche. Therefore, understanding which mechanisms drive enhanced ecosystem functioning and when they do so is crucial to predicting the consequences of species loss (Barry et al. In this case rather than geographically excluding each other the two shark … (2017) found that, at some grassland sites, a positive biodiversity–productivity relationship was driven by reduced performance in monoculture over time. 2. (2016) found that plant communities did not use different foliar architecture to intercept more light in mixture in spite of overall higher biomass production. The temporal axis of niche (temporally based resource partitioning) is an understudied mechanism for resource partitioning in mammals even though it provides a potential means for species coexistence. Alternatively, Jesch et al. 2012 for nitrogen, Eisenhauer et al. However, contrary to our predictions, we found little evidence for spatial resource partitioning along vertical resource gradients in more diverse grassland communities. 2017) for each individual data set. Yet, the mechanisms driving these often‐positive biodiversity–ecosystem functioning relationships are not well understood. How do leaf trait values change spatially and temporally with light availability in a grassland diversity experiment? To test this hypothesis, we assess (1) as a prerequisite, if plant species richness enhances community biomass production or resource uptake at these sites. We were able to collect 21 total data sets: 12 aboveground biomass by canopy height, 6 belowground biomass by soil depth, 1 nitrogen uptake by soil depth, 1 nitrogen and potassium uptake by soil depth, and 1 water uptake by soil depth. the use of one species as a resource by another species. The majority of predictions for species loss are predicated on the assumption of spatial resource partitioning, an assumption that is not supported empirical evidence for these grasslands. 2019). 2017, Weisser et al. species reduce competition by utilizing same resource in different habitats. The division of resources by species to help avoid competition in an ecological niche is called resource partitioning. The combination of intraspecific and interspecific competition is important in relation to species. 2014). The study conducted in the Montpellier European Ecotron benefited from the CNRS human (Damien Landais, Sebastien Devidal, Clement Piel, and Olivier Ravel) and technical resources allocated to the ECOTRONS Research Infrastructure as well as from the state allocation ‘Investissement d'Avenir’ ANR‐11‐INBS‐0001. 2007, da Silva et al. Of these 21 data sets, 19 reported either total community resource uptake or total community biomass. When organisms compete for limited resources, there are two primary types of competition: intraspecific and interspecific. Almost all data sets currently available for grassland biodiversity–ecosystem‐functioning experiments provide data at spatial increments of 10 cm or greater (but see Bachmann et al. Effects of tree species richness on fine root production varied with stand density and soil nutrients in subtropical forests.
