Per-Arne Amundsen
Professor in freshwater ecology
Job description
Freshwater fish ecology
I am a freshwater fish ecologist interested in the ecology and management of northern freshwater systems with special emphasis on food web and trophic interactions and the impact of stressors like biological invasions, climate change, habitat modifications and pollution. My main research activities are related to long-term ecological studies on the role of predation, parasitism and competition in the population and community ecology of freshwater fish.
