J Exp Biol (2021) 224 (6): jeb237891.
Published: 15 March 2021
...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 of...

...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 to...

...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...
