Intraspecific phylogeography of Lacerta vivipara and the evolution of viviparitySurget-Groba, Yann ...The lacertid lizard Lacerta vivapara is one of the few squamate species with two reproductive modes. We present the intraspecific phylogeny obtained from neighbor-joining and maximum-parssimony ... analyses of the mtDNA cytochrome b sequences for 15 individuals from Slovenian oviparous populations, 34 individuals from western oviparous populations of southern France and northern Spain, 92 specimens from European and Russian viviparous populations, and 3 specimens of the viviparous subspecies L. v. pannonica. The phylogeny indicates that the evolutionary transition from oviparity to viviparity probably occurred once in L. vivipara. The western oviparous group from Spain and southern France is phylogenetically most closely related to the viviparous clade. However, the biarmed W chromosome characterizing the western viviparous populations is an apomorphic character, whereas the uniarmed W chromosome, existing both in the western oviparouse populations andin the geographically distant eastern vivaparous populations, is a plesiomorphic character. This suggests an eastern origin of viviparity. Various estimates suggest that the oviparous and viviparous clades of L. vivipara split during the Pleistocene. Our results are discussed in the framework of general evolutionary models: the concept of an oviparity-viviparity continuum in squamates, the cold climate model of selection for viviparity in squamates, and the contraction-expansion of ranges in the Pleistocene resulting in allopatric differentiation.Vir: Molecular phylogenetics and evolution. - ISSN 1055-7903 (Vol. 18, no. 3, 2001, str. 449-459)Vrsta gradiva - članek, sestavni delLeto - 2001Jezik - angleškiCOBISS.SI-ID - 6728214
