Life-history genotype explains variation in migration activity in Atlantic salmon ( Salmo salar )
One of the most well-known life-history continuums is the fast–slow axis, where ‘fast’ individuals mature earlier than ‘slow’ individuals. ‘Fast’ individuals are predicted to be more active than ‘slow’ individuals because high activity is required to maintain a fast life-history strategy. Recent met...

One of the most well-known life-history continuums is the fast–slow axis, where ‘fast’ individuals mature earlier than ‘slow’ individuals. ‘Fast’ individuals are predicted to be more active than ‘slow’ individuals because high activity is required to maintain a fast life-history strategy. Recent meta-analyses revealed mixed evidence for such integration. Here, we test whether known life-history genotypes differ in activity expression by using Atlantic salmon ( Salmo salar ) as a model. In salmon, variation in Vgll3, a transcription cofactor, explains approximately 40% of variation in maturation timing. We predicted that the allele related to early maturation ( vgll3 *E) would be associated with higher activity.
