Research interests

I am studying behavioural variation among salmonids using an interdisciplinary approach evolving both molecular and physiological tools. I presented my thesis (Behavioural tactics and domestication effects in salmonids) in 2002 where my main aim was to examine variation among individuals in relation to selection in wild and hatchery environments. I am also interested in how various behavioural tasks can be reflected in the cardio-ventilatory response and together with Michael Axelsson from the department of Zoo Physiology I have developed a non invasive method to detect heart rate on free swimming fish.

My recent projects evolve a 2 year Post Doc (Habitat adaptations in salmonids, effects of intra- and inter-specific competition) at Cardiff School of Biological Science in Wales hosted by Dr Siân Griffiths. At present I am working on a project (Behavioural variation in salmonids; implications for performance in the wild and stocking) to examine fitness variation in families of brown trout adopting different behavioural strategies. In addition I am also evolved in a project regarding intraspecific competition in salmonids (Asymmetric competition and population structure in juvenile brown trout) together with Rasmus Kaspersson.

The results from my research can aid in understanding local adaptation and the structuring of populations, which in turn may facilitate development of stocking tools as well as guidelines for protection and restoration of salmonid populations.
