English: Distribution map of Podarcis lizards in the Iberian Peninsula and North Africa. Original figure legend: Geographical origin and mitochondrial DNA assignment of samples used in this study. A. Map of the Iberian Peninsula and the Maghreb showing the putative distribution of mtDNA lineages based on a compilation of available data and samples analysed in this study. The dashed line represents the distribution of the Iberian-Maghrebian clade of Podarcis; the dotted line represents the limits of the Iberian distribution of P. muralis. B. Maximum-likelihood tree of the mitochondrial gene ND4 for the samples analysed. Bootstrap values over 50% are shown. Figure published in BMC Evolutionary Biology, under their Open Access feature.
