Long-term and Climate Impact Research of Lake Ecosystems
We are interested in the long-term development of lake ecosystems and their resilience against disturbances; particularly in the temporal scales (minutes to decades) which govern the dynamics of the thermal- and nutrient regime, plankton communities, biodiversity and lake metabolism in the context of global environmental change. We combine statistical modelling with ecological theory to identify mechanisms driving the nature of long-term change (linear versus non-linear), to quantify critical thresholds causing abrupt changes and to understand the emergence and maintenance of plankton biodiversity. We base our research on decadal data from our prime case study site Lake Müggelsee, located in the suburban area of Berlin, and lakes around the world through international networks such as GLEON and Netlake. Continuous high resolution data of meteorological, physical and biological data from our automatic Müggelsee lake station allow us to study the resilience of lakes towards short term episodic events such as storm or heat extremes. New Sentinel satellite data enable us to extend our research on e.g. metabolism to lakes globally at high spatial and temporal scale. Overall, our research contributes to the understanding as to how lake ecosystems will be affected by global climate change.
