International audience Intraspecific diversity is of paramount importance for species adaptation to global changes. Alternative mating tactics have important ecological and evolutionary implications and are determined by complex interaction between environmental and genetic factors potentially involving phenotypic plasticity.

The research project GenEarly combines experimental ecology, quantitative genetics and population genomics approaches and use the state of the art in sequencing technology to shed new light on the genetic determinism and the genomic architecture on alternative reproductive tactics in Atlantic salmon natural populations.
