Sampling sites and geographic distribution of mtDNA lineages for 653 grass snakes (Natrix natrix; top) and 325 dice snakes (N. tessellata; bottom) used in this study (eastern parts of the distribution ranges). For N. tessellata, data outside Turkey are from Guicking et al. (2006, 2009) and Kyriazi et al. (2013).
