Responses of plants and ecosystems to global environmental change

Plants are fundamental components of the earth system. Their ability to assimilate atmospheric CO2 and to transpire H2O drives the biogeochemical cycles in ecosystems and determines as such the provision of ecosystem goods and services that we as people depend on. In the Physiological Plant Ecology Group at ETH Zurich we investigate the physiological responses of plants to their environmental in order to understand how plants govern the function of ecosystems in a changing world. Our research operates at different scales that range from the leaf to the landscape level and links plant ecophysiology to plant population dynamics and ecosystem biogeochemistry.
