摘要: Aim We assessed genetic relationships among populations for each of the four snake species found on Crete (Zamenis situla, Hierophis gemonensis, Telescopus fallax and Natrix tessellata), including conspecific from Aegean area. Our aim was to reconstruct their phylogeographical histories, especially regarding occurrence Crete. Location Crete, Sea eastern Mediterranean. Methods Genetic diversity were based sequences mitochondrial marker cytochrome b, applying phylogenetic analyses (maximum likelihood, Bayesian inference neighbour-joining), a median-joining network analysis molecular dating analysis. Results The Z. situla phylogeny includes clade with specimens Crete, Peloponnese Thera, while Turkey, northern Greece islands form separate clade. The H. gemonensis tree also presents two clades: one comprising Kythera, another representing continental part species' distribution. For N. tessellata, Cretan are as sister Europe western Turkey. A more complex structure is in T. fallax: Thera Antikythera clade, which itself forms ‘western’ an ‘eastern’ Cyprus. splits resulting clades tessellata occurred at end Miocene Pliocene/Pleistocene boundary, respectively. lineages diversified during Pleistocene. Main conclusions Zamenis exhibit pattern that involves transmarine dispersal southern (possibly by humans case situla). explained natural west isolation vicariance. Although these patterns have been inferred other studied herptiles unique south-western Turkey Crete.
