Ecosystem Functioning and Global Change

Research in the Grassland Sciences group focuses on the process- and system-oriented understanding of functional plant diversity and of ecosystem biogeochemistry, in particular biospheric-atmospheric greenhouse gas exchange, both in response to human and biophysical drivers, across spatial and temporal scales.

Based on a multidisciplinary approach, we use classical ecological methods and further develop innovative tools, such as stable isotope analyses and micrometeorological measurements, in our observational and experimental studies.
