Application of DNA Barcoding to the Study of Green Lizards (Sauria: Lacertidae: <i>Lacerta</i>)

Abstract

DNA barcoding remains a recognized and widely used method for taxon identification in biodiversity inventory and monitoring. In this publication, we present information about the results of using this method in the study of green lizards of the genus Lacerta. A total of 67 sequences of the COI gene fragment of three species (L. agilis, L. media, L. strigata) were analyzed. For the first time, all subspecies of L. agilis known in the Caucasus were studied using DNA barcoding, and a phylogeographic hypothesis for L. strigata in the Caucasian part of the range was proposed. Genetic identification has been successful at the species level. In the composition of L. agilis within the Caucasus, we can diagnose only the subspecies L. a. boemica and L. a. exigua, while L. a. brevicaudata, L. a. grusinica and L. a. mzymtensis are identical from L. a. exigua, while L. a. ioriensis from L. a. boemica.
