a Phylogenetic haplotype recostruction of the cytb data set obtained with MrBayes. At each node, MrBayes and BEAST posterior probability and TMRCA with 95% highest posterior density (HPD) intervals are respectively reported. The seven clade such as its nested haplogroups are depicted with different colors. b Geographic distribution of the mtDNA haplotypes in Podarcis siculus. Pie diagrams shows the haplotype frequencies at each sampled location and are colored according to the main haplogroups identified by the phylogeny. c Statistical parsimony networks of the seven mtDNA clades identified by the phylogeny. Each circle size is proportional to their frequencies and each filled rectangles representing one substitution. The different colors within each network depict the principal identified haplogroups. Circum-Sicilian and Corsica-Sardinia haplotypes are reported in bold with different colors (violet: Aeolian haplotypes; blue: Aegadian haplotypes, green: Sardinia and Corse haplotypes, yellow; Isola Bella haplotypes)
