Temporally stable genetic structure and low migration in an Atlantic salmon population complex: implications for conservation and management.

ABSTRACT: The evolutionary potential of a population is closely related to two key population genetic parameters, namely the effective population size (N e) and migration rate (m). Furthermore, knowledge of these parameters is required in order to assess potential constraints on local adaptation and for the development of biologically sound management strategies. We addressed these key issues by investigating the temporal and spatial genetic structure of over 2000 adult Atlantic salmon (Salmo salar) collected from 17 sites in the Teno and Näätämö rivers in northernmost Europe with up to five time points spanning temporal intervals up to 24 years (∼4 generations). In all cases except one, local populations were found to be temporally stable within the river system. Estimates of N e were generally a m
