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

Last changed: 23 April 2024

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 & us.

What’s up: We welcome BSc-student Ida and MSc-student Samuel, working on warming effects on fish condition, and on intra-specific variation in bioaccumulation of radionuclides in fish!


Our research:

  • Climate change effects on fish and food webs: effects of warming and deoxygenation
  • Extreme weather effects on food webs and risks to fisheries.
  • Fisheries- and warming-induced evolution in fish communities
  • Eutrophication and light limitation in aquatic food webs
  • Community dynamics and effects of fishing: methods for inference and management
  • Bioaccumulation in aquatic food-webs through community dynamics
  • Aquatic food web responses to variation in land-use practices
