Our research focuses on experimental studies of pelagic food webs in limnic and marine waters. All global biogeochemical cycles are essentially determined by the life cycle of pelagic organisms; e.g. the flux of carbon from the atmosphere into food webs through photosynthesis of phytoplankton.
Current research programmes are investigating the efficiency of this transfer as a function of the functional diversity of phytoplankton communities, which is partly determined by the different pigmentation of individual phytoplankton species. Furthermore, experimental tests of theoretical food web models in simply structured marine and freshwater ecosystems are currently being carried out.
Experimental analyses of aquatic food webs can help to causally link well-understood findings from theory and laboratory experiments with field observations. To do this, it is necessary to be able to carry out experimental studies in the field on a large number of different water bodies. The Seeon Limnological station (SLS) is located within an area of more than 50 lakes and the possibilities for conducting large-scale field experiments. T
