Structural changes to the uterus of the dwarf ornate wobbegong shark (Orectolobus ornatus) during pregnancy
Published 2020Abstract Embryos of the viviparous dwarf ornate wobbegong shark (Orectolobus ornatus) develop without a placenta, unattached to the uterine wall of their mother. Here, we present the first light microscopy study of the ...Open AccessArticle -
Seahorse brood pouch morphology and control of male parturition in Hippocampus abdominalis
Published 2022Introduction Syngnathids (seahorses, pipefishes and seadragons) are among the few vertebrates that display male pregnancy. During seahorse pregnancy, males incubate developing embryos embedded in a placenta within a fleshy ...Open AccessArticle -
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
