EEMS analysis of 428 samples of Bluefin tuna from the Mediterranean and off Morocco coasts based on 13 microsatellite loci. Empty circles correspond to the studied geographic sites with their sizes being proportional to the number of samples analyzed in the present study. a, b Averaged, over different grids, effective migration rates (m), and diversity contour plots (q) respectively, c diagnostic plot of MCMC iterations vs log posterior of all runs (n = 15) where there is no indication of non-convergence, d scatterplot of the observed between demes pairwise genetic differences against the geographic distances of the demes (Great circle distances in Km). The coefficient of determination is indicated at the top left of the scatterplot (R2 = 0.053). Outliers of the analysis are depicted with a red ellipse and describe genetic dissimilarities related to Vibo samples (Italy)
