Principal Component Analyses for microsatellite data of pure Natrix tessellata (n = 52). The same dataset was used as for structure analyses. Samples are colored according to their mitochondrial lineage or structure cluster membership. Thresholds for admixed samples were the same as used for structure. Oval outlines correspond to 95% confidence intervals. PC1 explains 6.65% of variance, PC2 5.23%, and PC3 5.08%.
