Summary of the results of discriminant analysis of principal components (DAPC) for 321 Pachygrapsus marmoratus individuals. a, number of individuals from each sampling site (vertical axis) assigned to each of the four inferred genetic clusters (horizontal axis). The size of black squares is proportional to the number of individuals assigned to each cluster (lower legend). b, DAPC compoplot showing the assignment of individuals to genetic clusters. Each individual is represented by a vertical bar, and colours indicate the probability of an individual’s membership in one of four genetic clusters. c, ordination plot for the first two discriminant axes. Dots represent individuals connected to the center of an inertia ellipsis, which indicates assignment to one of the four genetic clusters inferred by DAPC. d, DAPC with original sampling sites as clusters. Geographical origin of each population is depicted in the plot by colours and individuals are represented by dots. Location acronyms as in Fig. 1
