Results of the STRUCTURE analysis showing the distribution of individual genetic variation among different putative genetic clusters. Individual genotypes are represented by vertical bars along the x-axis, with the proportion of membership to K genetic clusters indicated by the different colours on the y-axis. Individuals are grouped by localities along the x-axis corresponding to Gironde, Tejo, Algarve, Guadalquivir, Banc d’Arguin and Senegal.
