| molecular phylogeography of the nose-horned viper (vipera ammodytes, linnaeus (1758)): evidence for high genetic diversity and multiple refugia in the balkan peninsula. | the nose-horned viper (vipera ammodytes) occurs in a large part of the south-eastern europe and asia minor. phylogenetic relationships were reconstructed for a total of 59 specimens using sequences from three mitochondrial regions (16s and cytochrome b genes, and control region, totalling 2308 bp). a considerable number of clades were observed within this species, showing a large genetic diversity within the balkan peninsula. splitting of the basal clades was evaluated to about 4 million years a ... | 2008 | 18267369 |
