Canonical Variate Analysis (CVA) of dorsal (a) and lateral (b) landmark coordinates for grass snakes assigned to the microsatellite clusters of Natrix helvetica (E, C-VS, C-TI) and N. natrix (N. n. vulgaris, mtDNA lineage 3, from northeastern Switzerland). Only individuals with a genotypic cluster assignment ≥ 80% are included; circles represent 95% confidence ellipses.
