Effects of plant species richness on stand structure and productivity
Aims Aboveground biomass production commonly increases with species richness in plant biodiversity experiments. Little is known about the direct mechanisms that cause this result. We tested if by occupying different heights and depths above and below ground, and by optimizing the vertical distribution of leaf nitrogen, species in mixtures can contribute to increased resource uptake and, thus, i...
متن کاملSpecies richness and aggregation effects on the productivity of ruderal plant communities under drought perturbation
The effect of species richness and spatial aggregation on the stability of community productivity in response to drought perturbation was investigated with experimental plant communities. Communities comprising all singleand three-species combinations of the ruderal species, Capsella bursa-pastoris, Tripleurospermum inodorum, Poa annua, and Stellaria media, were established in glasshouse. Habit...
متن کاملEffects of plant host species and plant community richness on streptomycete community structure.
We investigated soil streptomycete communities associated with four host plant species (two warm season C4 grasses: Andropogon gerardii, Schizachyrium scoparium and two legumes: Lespedeza capitata, Lupinus perennis), grown in plant communities varying in species richness. We used actinobacteria-selective PCR coupled with pyrosequencing to characterize streptomycete community composition and str...
متن کاملProductivity is a poor predictor of plant species richness.
For more than 30 years, the relationship between net primary productivity and species richness has generated intense debate in ecology about the processes regulating local diversity. The original view, which is still widely accepted, holds that the relationship is hump-shaped, with richness first rising and then declining with increasing productivity. Although recent meta-analyses questioned th...
