Our research capitalizes on the unique opportunities provided by the simple genetic architecture of salmon age at maturity, combined with the strengths of Atlantic salmon as a model for functional genomic, ecological and evolutionary research. Our aim is to link genotype, phenotype and fitness of this important life-history trait using approaches ranging from investigating the cellular-level processes in the laboratory to estimating reproductive success in completely natural populations. We also apply the knowledge we obtain for improving conservation and management of this iconic species. Our research is funded by the ERC, the Academy of Finland as well as other local agencies.
