My research effort is mainly aimed at understanding the observed large variation in life history traits in freshwater fish (but other organisms are also of interest). What drives this diversity? Selection or plasticity? What kind of selection? What selects for plasticity? Together with students and colleagues, I study why various populations of freshwater fish behave so differently and have so different life histories. We have focused our research on traits such as growth, age at maturation, fecundity and egg size, since these traits are very important for fitness and also for population dynamics.
To study this, we use a combination of methods such as classical field observations linked with field experiments (in particular using capture-mark-recapture techniques), laboratory experiments, and quantitative genetic studies. Recently we have also started using molecular genetic studies in our effort to understand evolutionary and ecological processes at different spatial and temporal scales.
To study these questions collaboration is needed, and I maintain collaborations both internally and externally (in Norway and the rest of the world). To do science today is really a collaborative effort.
