Abstract |
Podarcis peloponnesiacus, commonly known as Peloponnese lizard, is an endemic lizard of Peloponnesos. Although the phylogeny of the genus Podarcis has been repeatedly studied, the intraspecific relationships of P. peloponnesiacus are not yet well defined. However, there are indications for the presence of two highly differentiated branches within the species. The aim of our study is to clarify the taxonomic status of the species, reveal its intraspecific diversity, and investigate the phylogenetic relationship among P. peloponnesiacus, P. lenendis and P. cretensis by analyzing 2 mitochondrial (Cytb & 16S rRNA) and 6 nuclear (Pod55, MC1R, Rag1, Pod15b, NKTR, UBN1) gene fragments for a total of 193 P. peloponnesiacus individuals, 2 P. lenendis, 4 P. cretensis. Two specimens of P. erhardii were used as outgroup. Several phylogenetic (Maximum Likelihood and Bayesian Inference), species delimitation (BP&P), and chronophylogenetic analyses were performed, revealing two highly supported and diversified clades with a distinct geographic pattern. The splitting of the two clades dates back to Pleistocene and is probably due to paleographical and palaeoclimate events. Moreover, the genetic distances between the two clades of P. peloponnesiacus are close to the interspecies distances within the genus in Balkans, while the relationship between P. peloponnesiacus, P. lenendis and P. cretensis remains unresolved.
