Genetic distances and isolation-by-distance plot in Vesubia jugorum. a Heatmap showing the pairwise % uncorrected p-distances within and between sampling localities, with darker colours indicating higher distances. Black outlines show the intra-group distances. Abbreviations of the localities are explained in Fig. 2 and in Table 1. b Genetic distances plotted against geographic distances, with the interpolation line in red
