Mechanisms and Adaptations

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.

A Successful Third Workshop on Trait-Based Approaches to Ocean Life
How can the essential properties of community structure and ecosystem functioning be captured from a limited number of traits in organisms? 120 researchers from 31 nations met over four days at Solstrand to answer this question.

New Paper on Sea Ice Loss and Changing Pelagic Interactions
The Arctic sea-ice cover is rapidly shrinking and light increasingly reaches the previously darkened waters. A new paper predicts that increased visibility helps fish that hunt by sight to detect their prey, which can expand their distribution poleward. However, the foraging gains will be limited to the summer months, as the polar nigh remains dark regardless of sea-ice loss, a seasonality favouring migratory fish.

Evolution of Virulence in Salmon Lice Covered by The Scientist
One of our recent scientific papers, published in Journal of Evolutionary Biology and coauthored by Mathias Ugelvik, Olav Moberg, Arne Skorping, and Adele Mennerat, is discussed in popular science journal The Scientist. Virulence of salmon lice from farmed areas appears higher than that of lice from wild areas, providing correlative support to theoretical studies predicting evolution of higher virulence in parasites and pathogens of farmed fish.
