Hydrological-ecological processes

Effects of land use, transport and in-stream processing on nutrients

Research interests

We investigate the relationship between ecosystem processes in streams and the characteristics of the hydrological stream catchment. In our work, we primarily use experimental approaches and focus on the direct and indirect effects of land use in the stream catchment. In our experimental approaches, we combine concepts from ecological stoichiometry, biogeochemistry, fluvial ecology, and catchment science to develop novel approaches for integrative ecosystem management.

Our research is closely connected to the work of other researchers from different disciplines. In addition to the highly interlinked research within our department, we cooperate with researchers from the departments River ecology, Hydrogeology and Lake research, as well as research from the research units  Chemicals in the Environment und Smart Models/ Monitoring. Outside UFZ we also cooperate with different researchers, for example colleagues from the Wassercluster Lunz (Dr. Gabriele Weigelhofer) in Austria, the James-Hutton-Institute in Scotland (Prof. Marc Stutter) und the Aarhus University (Prof. Brian Kronvang) in Denmark.

Methods

  • We investigate land use effects on ecosystem state variables, ecological functions and biogeochemical cycles of streams.
  • We use experimental investigations at different scales to develop novel approaches for integrative ecosystem management of streams.
  • In our work, we combine measurements by in-situ sensors, stable isotope approaches, biological process measurements and chemical laboratory measurements.
  • We focus on the sources, stoichiometry, and processes of dissolved organic carbon, dissolved nitrogen and dissolved phosphorus fractions in stream networks.
