Plant, Soil and Ecosystem Processes

The Research Group Plant, Soil and Ecosystem Processes studies biogeochemical processes related to the carbon, nitrogen and water cycles in (mostly) mountain ecosystems in response to changing climate and land use. In situ experimental manipulations are designed to unravel the mechanisms underlying observed patterns. Emphasis is laid on plant-soil interactions and the role of plants and their functional traits in ecosystem processes. A range of ecophysiological techniques are employed to study the gas exchange of above- and belowground plant organs, soil respiration and the net ecosystem exchange (NEE) of CO2, as well as CH4, N2O and H2O. Collaborations permit explicit consideration of microbial communities and processes. Isotopic techniques are applied to trace fluxes of carbon, nitrogen and water in response to environmental change.
