“…Monophyly of the viviparous group was recovered from ND4-tRNA LEU data, which is consistent with the previous hypothesis (Guo and Wang, 2007;Pang et al, 2003). To date, however, the intrarelationship of viviparous species is still equivocal.…”

especially in the context of Quaternary and Holocene histories of regional biotas (Hewitt, 2001). The dramatic geological and climatic history and striking habitat diversity of the Qinghai-Tibetan Plateau (QTP), ranging from broad plantation surfaces, basins to mountain ranges, have made it a geographic focus of many phylogeographic studies Qu et al., 2010;Xu et al., 2010;Zhan et al., 2011). As reviewed by Yang et al. (2009), the geomorphic and climatic changes on the plateau during the Quaternary have a remarkable influence on regional and adjacent biogeographic patterns.The Quaternary glaciations in the QTP and the bordering mountains were the consequence of a combination between climate and local tectonic uplift. The diversification of P. putjatia may be triggered by the tectonic movement in the Huangshui River valley during the C phase of Qingzang Movement. Subsequently, the glacial climate throughout the Pleistocene may have continued to impede the gene flow of P. putjatia, eventually resulting in the genetic divergence of P. putjatia in the allopatric regions. Demographic estimates revealed weak population expansion in one lineage of P. vlangalii (A2, the Qaidam Basin lineage) and one lineage of P. putjatia (B2, the north Qinghai Lake lineage) after approximately 42 000 years before present. However, constant population size through time was inferred for two lineages (A1 and B1), the source of Yellow River lineage of P. vlangalii and the southeast of Qinghai Lake lineage of P. putjatia, possibly due to stable populations persisting in areas unaffected by glacial advances. Our results also suggest: 1) at least four differentiated lineages of P. vlangalii complex may have evolved allopatrically in different regions during the Pleistocene glaciation events; 2) in support of several recent studies, P. putjatia is a valid species, having a more wide distribution than previously considered; and 3) a hypothesis referring to P. v. hongyuanensis, inhabiting in the source region of the Yellow River, being synonymous with P. v. pylozwi is supported.

Are viviparous lizards more vulnerable to climate warming because they have evolved reduced body temperature and heat tolerance?

Lizards may experience population declines and extinctions on a similar scale to that experienced by amphibians, and climate warming is one hypothesis proposed to explain these declines and extinctions. Within lizards, viviparous species are hypothesized to be more vulnerable to climate warming, because they have evolved reduced body temperature and heat tolerance, but this idea remains untested. To test this hypothesis, we conducted three temperatures (20, 24, and 28 °C) × two species [Phrynocephalus przewalskii (oviparous) and P. putjatia (viviparous)] factorial design experiment that simulated warming on oviparous versus viviparous lizards. Our manipulation of ambient temperature affected activity and thermal preference in both species, birth date in P. putjatia, and egg mass in P. przewalskii; other examined traits (fecundity, reproductive output, and size, morphology, and sprint speed of offspring) were not affected. Neither in P. putjatia nor in P. przewalskii behavioral responses to rising temperatures differ between the sexes. The viviparous species thermoregulated more actively than did the oviparous species, but the two species did not differ in thermal preference. Warming reduced the activity time allotted for thermoregulation in both species, but the effect was more dramatic in the viviparous species. Our data support one of the central predictions that lead to the hypothesis that viviparous lizards are more vulnerable to climate warming; however, this is not because viviparous lizards have evolved reduced body temperature and heat tolerance, but, because warming constrains activity more dramatically in viviparous species.
