The Theoretical Ecology Group is a joint research group of the University of Bergen, Uni Research, and the Institute of Marine Research in Bergen Marine Research Cluster, hosted by Department of Biology at UiB.

Our aim is to understand how processes at the level of individuals drive dynamics of populations and communities. We focus on individual trade-offs and use trait-based models to explain ecological and evolutionary patterns. Please navigate through our pages to read more about our Research, our Publications, and us.

We organize weekly Hjort seminars on marine ecosystem dynamics.

The group is well connected and networked. It is a node in the Nordic Centre of Excellence NorMER - Nordic Centre for Research on Marine Ecosystems and Resources under Climate Change. We are also member of the EU COST action Conservation Physiology of Marine Fishes.

Love Thy Neighbour
A News & Views article by Ben Sheldon and Marc Mangel in Nature this week highlights the recent paper in PLoSONE by Theoretical Ecology Group researchers Eliassen and Jørgensen. In the article, Sheldon and Mangel argue that the new model represents an important shift in focus for empirical studies of extra-pair mating, and that it also has broad implications for our understanding of the evolution of cooperation among unrelated individuals.
