My main interest focus in the understanding of system ecological processes of lakes and how they are influenced by global change. My studies are based on long term field as well as experimental data but maintain a close link between data driven analysis and ecological theory as well as results from ecosystem models. An integrative use of these three tools is in my understanding most beneficial to successfully develop our mechanistic understanding of ecosystem processes further. Such an understanding is not only of fundamental interest but also enables us to better predict the effects of multiple changing ecosystem drivers on ecosystem processes.

My methodological approaches comprise statistical modelling, time series analysis, mathematical optimization, mesocosm experiments

Specific expertise:

  • Climate change and eutrophication
  • Threshold-driven changes in lake ecosystems
  • Abrupt changes in zooplankton community composition with specific consideration of external and internal drivers
  • Effects and interacting effects of nutrients, temperature and water level changes on metabolism and the metabolic balance of lakes
  • Difficulties in the application of the 24 h oxygen curve method to estimate metabolic rates in small wind sheltered lakes dominated by horizontal convective mixing
  • Influence of stratification on lake metabolism and metabolic balance
  • Capability of early warning signals to predict impeding regime shifts based on empirical long term data
