The role of stoichiometry for biodiversity and ecosystem functioning
Research on ecological stoichiometry and on the effects of biodiversity on ecosystem processes has developed more or less independently, whereas potentially strong interactions exist, not the least because changing biodiversity and changing biogeochemical cycles belong to the major anthropogenic changes in many ecosystems. Here, I will present experimental studies from both plankton and terrestrial ecosystems analyzing the effect of producer biodiversity on the use of multiple elements and under different nutrient supply ratios. Further, I will show how diversity-mediated changes in producer tissue chemistry affect aquatic and terrestrial consumer performance and efficiency.
