Genotyping the phenotypic diversity in Aegean Natrix natrix moreotica (Bedriaga, 1882) (Reptilia, Serpentes, Natricidae).

We examined the mitochondrial identity of Aegean Natrix natrix moreotica representing different morphotypes, with a focus on new material from Milos and Skyros. We found no correlation between distinct morphotypes and mitochondrial identity. Our results support that grass snake populations are polyphenetic and that southern subspecies, including island populations, show a higher variability than northern ones. [ABSTRACT FROM AUTHOR]
