Structure and permeability of the egg capsule of the placental Australian sharpnose shark, Rhizoprionodon taylori
Published 2022Shark placentae are derived from modifications to the fetal yolk sac and the maternal uterine mucosa. In almost all placental sharks, embryonic development occurs in an egg capsule that remains intact for the entire ...Open AccessArticle -
A comparison of uterine contractile responsiveness to arginine vasopressin in oviparous and viviparous lizards
Published 2020Nonapeptides and their receptors regulate a diverse range of physiological processes. We assessed the contractile responsiveness of uteri from the squamate viviparous-oviparous species pair, Pseudemoia entrecasteauxii and ...Open AccessArticle -
Emergence of an evolutionary innovation: Gene expression differences associated with the transition between oviparity and viviparity
Published 2020Abstract Our understanding of the evolution of complex biological traits is greatly advanced by examining taxa with intermediate phenotypes. The transition from oviparity (egg-laying) to viviparity (live-bearing) has ...Open AccessArticle -
The evolution and physiology of male pregnancy in syngnathid fishes
Published 2020The seahorses, pipefishes and seadragons (Syngnathidae) are among the few vertebrates in which pregnant males incubate developing embryos. Syngnathids are popular in studies of sexual selection, sex-role reversal, and ...Open AccessArticle -
Paternal nutrient provisioning during male pregnancy in the seahorse Hippocampus abdominalis
Published 2020Vertebrates that incubate embryos on or within the body cavity exhibit diverse strategies to provide nutrients to developing embryos, ranging from lecithotrophy (solely yolk-provided nutrition) to substantial matrotrophy ...Open AccessArticle
