Localization of Calbindin-D<sub>28k</sub> in Extra-Embryonic Membranes of Two Oviparous Scincid Lizards.
… membrane and yolk sac of oviparous squamate reptiles (lizards and snakes) transport calcium from the eggshell and yolk to the developing embryo. I used immunohistochemistry to localize calbindin-D<sub>28K</sub> expression in the chorioallantoic membrane and yolk sac of two species of …

Adaptive evolution, sex-linkage, and gene conversion in the voltage-gated sodium channels of toxic newts and their snake predators
… across all nine sodium channel genes in squamate reptiles and show how historical changes have paved the way for full-body resistance in certain snakes. Finally, I use targeted sequence capture to obtain the sodium channel sequences of salamanders and show evidence that tetrodotoxin …

Physiological and behavioral consequences of reptilian life in the slow lane: Ecology of beaded lizards and rattlesnakes.
Although reptiles are well known for their low energy requirements and high efficiencies of biomass conversion, few studies have addressed the ecology and energetics of species with very low activity levels. I investigated the ecology and energetics of two such reptilian groups: helodermatid …

Physiological and Ecological Constraints on the Evolution of Viviparity in Sceloporine Lizards
The purpose of this study was to evaluate putative physiological and ecological constraints on the evolution of viviparity in sceloporine lizards. In Chapters one and two, I investigated the role of in utero oxygen availability as a constraint on the capacity to support embryonic development during …
