The adaptive significance of reptilian viviparity in the tropics: testing the maternal manipulation hypothesis.

Evolution; international journal of organic evolution - 1 Jan 2006

Webb Jonathan K, Shine Richard, Christian Keith A

Abstract excerpt

Phylogenetic transitions from oviparity to viviparity in reptiles generally have occurred in cold climates, apparently driven by selective advantages accruing from maternal regulation of incubation temperature. But why, then, are viviparous reptiles so successful in tropical climates? Viviparity might enhance fitness in the tropics via the same pathway as in the temperate zone, if pregnant female reptiles in the...
