Primmer's research group uses Atlantic salmon as a model for integrative functional genomic, ecological and evolutionary research. Current research aims to uncover the genetic mechanisms that lead to the remarkable diversity of reproductive ages in Atlantic salmon as well as their ecological and evolutionary fitness consequences. It includes experiments ranging from analyses of molecular processes in salmon reared in controlled laboratory conditions to studying the reproductive success of wild salmon in remote populations in far north Finland. They also apply the knowledge we obtain for improving conservation and management of this iconic species.
