No Evidence of Complementary Water Use along a Plant Species Richness Gradient in Temperate Experimental Grasslands
Niche complementarity in resource use has been proposed as a key mechanism to explain the positive effects of increasing plant species richness on ecosystem processes, in particular on primary productivity. Since hardly any information is available for niche complementarity in water use, we tested the effects of plant diversity on spatial and temporal complementarity in water uptake in experime...
متن کاملPlant species composition and biofuel yields of conservation grasslands.
Marginal croplands, such as those in the Conservation Reserve Program (CRP), have been suggested as a source of biomass for biofuel production. However, little is known about the composition of plant species on these conservation grasslands or their potential for ethanol production. Our objective was to assess the potential of CRP and other conservation grasslands for biofuel production, descri...
متن کاملPlant species diversity and composition of experimental grasslands affect genetic differentiation of Lolium perenne populations.
Contrasting hypotheses exist about the relationship between plant species diversity and genetic diversity. However, experimental data of species diversity effects on genetic differentiation among populations are lacking. To address this, Lolium perenne was sown with an equal number of seeds in 78 experimental grasslands (Jena Experiment) varying in species richness (1, 2, 4, 8 to 16) and functi...
متن کاملDeclining plant species richness in the tussock grasslands of Canterbury and Otago, South Island, New Zealand
We studied vegetation change on 142 permanently marked transects spread throughout tussock grasslands of Otago and Canterbury, in areas subject to both pastoral and conservation management. The transects were established between 1982 and 1986 and re-measured between 1993 and 1999, providing a record of vegetation change at each site over an interval varying from 10 to 15 years. Each transect co...
متن کاملImpact of nitrogen deposition on the species richness of grasslands.
A transect of 68 acid grasslands across Great Britain, covering the lower range of ambient annual nitrogen deposition in the industrialized world (5 to 35 kg Nha-1 year-1), indicates that long-term, chronic nitrogen deposition has significantly reduced plant species richness. Species richness declines as a linear function of the rate of inorganic nitrogen deposition, with a reduction of one spe...
