Fish in food-webs: ecology & evolution of aquatic communities

Last changed: 11 October 2019

We link variation in body size and community composition to ecological and evolutionary dynamics in changing environments. In our research we combine dynamic models, experiments and analysis of long-term ecological data from lake, coast and open sea systems. More about our research and us.

Latest NEWS: we’re hiring! 2-year postdoc in Coastal Community Ecology.
