In the viviparous teleost Xenotoca...

...Nathaly Hernández-Díaz; Francisca Leal; Martha Patricia Ramírez-Pinilla ABSTRACT An exceptional case of parallel evolution between lizards and eutherian mammals occurs in the evolution of viviparity. In the lizard genus Mabuya , viviparity provided the environment for the evolution of yolk-reduced...

... (herbivore, insectivore, insectivore/carnivore, carnivore and omnivore), climate (tropical, temperate and arid), nocturnality, viviparity or family. We fitted models that included body mass and measurement temperature as covariates, and all possible combinations of other independent variables using ordinary...

...Alison Cree; Kelly M. Hare ABSTRACT Maternal basking regime can affect gestation length in viviparous squamates, but effects on offspring phenotype in species with extended pregnancies and ability to delay the birth season are unclear. We investigated the effects of three maternal basking regimes...

...Thomas Foucart; Olivier Lourdais; Dale F. DeNardo; Benoit Heulin Examination of the selective forces behind the transition from oviparity to viviparity in vertebrates must include an understanding of the relative energy costs of the two reproductive modes. However, interspecific comparisons...

...James R. Stewart; Tom W. Ecay; Benoit Heulin; Santiago P. Fregoso; Brent J. Linville SUMMARY The eggshell of oviparous lizards is a significant source of calcium for embryos, whereas the eggshell of viviparous lizards, when present, contains little calcium. In view of the potential cost...

...James R. Stewart; Tom W. Ecay; Benoit Heulin SUMMARY Embryos of oviparous squamate reptiles typically obtain calcium from both yolk and eggshell but differ from other oviparous amniotes (turtles, birds and crocodilians) because they are heavily dependent on calcium-rich yolk. Eggs of viviparous...

...Michael B. Thompson; Brian K. Speake; James R. Stewart; Kylie J. Russell; Ruth J. McCartney; Peter F. Surai ABSTRACT The ion, energy, lipid, nitrogen and fat-soluble vitamin contents of freshly ovulated eggs and neonates of the viviparous lizard Niveoscincus metallicus were measured to quantify...

...James R. Stewart; Michael B. Thompson ABSTRACT Vitellogenesis and placental transfer both contribute substantially to embryonic nutrition in the viviparous scincid lizard Pseudemoiaentrecasteauxii . Neonatal wet mass was 396% greater than egg wet mass and neonatal dry mass was 168% greater than egg...
