Popis
This population historically migrated as subyearling smolts, but in recent years, the yearling life history has become more common. Environmental conditions associated with dams and reservoirs might be exerting strong selection for alteration of life history traits that evolved over millennia. This project attempts to determine the extent to which these life history changes are due to evolution (genetic change) as opposed to phenotypic plasticity (non-genetic response to different environmental conditions).
