| geographical and temporal body size variation in a reptile: roles of sex, ecology, phylogeny and ecology structured in phylogeny. | geographical body size variation has long interested evolutionary biologists, and a range of mechanisms have been proposed to explain the observed patterns. it is considered to be more puzzling in ectotherms than in endotherms, and integrative approaches are necessary for testing non-exclusive alternative mechanisms. using lacertid lizards as a model, we adopted an integrative approach, testing different hypotheses for both sexes while incorporating temporal, spatial, and phylogenetic autocorrel ... | 2014 | 25090025 |
| nomenclatural issues in the psammodromus hispanicus (squamata: lacertidae) species group. | the psammodromus hispanicus species group has been recently shown to include three lineages that differ in morphology (san-jose et al. 2012), have largely parapatric range but exhibit little evidence of historical gene flow (fitze et al. 2011), leading to the recognition of these three lineages as distinct species (fitze et al. 2012). the eastern species can be unambiguously associated with the nomen lacerta edwarsiana dugès 1829, as the detailed information in dugès (1829) leaves no doubt that ... | 2015 | 26249429 |
| a new anoplocephalid (cestoda) from tarentola parvicarinata (lacertilia: gekkonidae) in senegal (west africa). | the present study presents the description of oochoristica beveridgei n. sp. (linstowiinae fuhrmann, 1907). the species was found in the small intestine of tarentola parvicarinata joger (gekkonidae) in east senegal (west africa). among known species of oochoristica lühe, 1898, o. beveridgei is most similar to oochoristica junkea (johri, 1950) schmidt, 1986, found in gekko gecko (linnaeus) from india. a common feature of both species is the location of the cirrus sac, which lies anterior to the p ... | 2010 | 20491512 |
| ecological change predicts population dynamics and genetic diversity over 120 000 years. | while ecological effects on short-term population dynamics are well understood, their effects over millennia are difficult to demonstrate and convincing evidence is scant. using coalescent methods, we analysed past population dynamics of three lizard species (psammodromus hispanicus, p. edwardsianus, p. occidentalis) and linked the results with climate change data covering the same temporal horizon (120 000 years). an increase in population size over time was observed in two species, and in p. o ... | 2016 | 26666533 |
| integrative analyses of speciation and divergence in psammodromus hispanicus (squamata: lacertidae). | genetic, phenotypic and ecological divergence within a lineage is the result of past and ongoing evolutionary processes, which lead ultimately to diversification and speciation. integrative analyses allow linking diversification to geological, climatic, and ecological events, and thus disentangling the relative importance of different evolutionary drivers in generating and maintaining current species richness. | 2011 | 22129245 |
| population structure of three psammodromus species in the iberian peninsula. | the knowledge of a species' population structure is essential for the development of adequate conservation actions as well as for the understanding of its evolution. the population structure is unknown in all species of the genus psammodromus, including the western sand racer (psammodromus occidentalis; a recently described species), the edward's sand racer (p. edwardsianus) and the spanish sand racer (p. hispanicus). in this article, the genetic variability and population structure of psammodro ... | 2015 | 26056622 |
