Description: Das Projekt "Biodiversity and Ecosystem Responses to Elevated CO2 in Calcareous Grassland" wird vom Umweltbundesamt gefördert und von Universität Basel, Departement Integrative Biologie, Botanisches Institut durchgeführt. This is a multidisciplinary long term project which aims at an understanding of plant and ecosystem processes under natural conditions when key environmental drivers are altered. Here we investigate the influence of elevated CO2 on species diversity and primary productivity of a highly diverse calcareous grassland. Biodiversity effects are explained by plant growth responses, water relations, soil processes and genotypic varience. We use a new CO2-enrichment technology-screen aided CO2-control (SACC) and also manipulated diversities. Leading Questions: Does biodiversity affect ecosystem functioning? Is biodiversity affected by elevated CO2 and how? What are the causes for species specific responses to elevated CO2? What are the longterm consequences of such changes for ecosystem functioning and species persistance (conservation)?
