Species differentiation of the rock lizard Darevskia (caucasica) complex (by DNA-barcoding data, cytochrome oxydase subunit I sequences)

Abstract

The results of molecular genetic analysis of phylogenetic relationships in Darevskia (caucasica) on the basis of COI sequences variability is presented. Two main lineages are detected: the Central and Eastern Caucasian (clades A–B — D. caucasica-D. daghestanica), and Central and Western Caucasian (clades C–D — D. alpina). A DNA-barcoding tool can be successfully used for species identification of D. alpina, D. caucasica and D. daghestanica. Refs 19. Figs 2. Tables 2.
