Development of the Axial Skeleton and Median Fin in the Australian Lungfish, Neoceratodus forsteri
New observations on the axial skeleton of the extant lungfish Neoceratodus forsteri (Dipnoi; Sarcopterygii) indicate that neural and haemal arch elements develop more independently than previously believed. For example, while the cartilaginous neural arches/spines begin development anteriorly, just behind the skull, the distal supraneurals first form separately in the posterior region of the ax...
متن کاملBrain – Endocast Relationship in the Australian Lungfish, Neoceratodus forsteri, Elucidated from Tomographic Data (Sarcopterygii: Dipnoi)
Although the brains of the three extant lungfish genera have been previously described, the spatial relationship between the brain and the neurocranium has never before been fully described nor quantified. Through the application of virtual microtomography (μCT) and 3D rendering software, we describe aspects of the gross anatomy of the brain and labyrinth region in the Australian lungfish, Neoc...
متن کاملExtremely Low Microsatellite Diversity but Distinct Population Structure in a Long-Lived Threatened Species, the Australian Lungfish Neoceratodus forsteri (Dipnoi)
The Australian lungfish is a unique living representative of an ancient dipnoan lineage, listed as 'vulnerable' to extinction under Australia's Environment Protection and Biodiversity Conservation Act 1999. Historical accounts indicate this species occurred naturally in two adjacent river systems in Australia, the Burnett and Mary. Current day populations in other rivers are thought to have ari...
متن کاملThe epithelial sodium channel in the Australian lungfish, Neoceratodus forsteri (Osteichthyes: Dipnoi).
Epithelial sodium channel (ENaC) is a Na(+)-selective, aldosterone-stimulated ion channel involved in sodium transport homeostasis. ENaC is rate-limiting for Na(+) absorption in the epithelia of osmoregulatory organs of tetrapods. Although the ENaC/degenerin gene family is proposed to be present in metazoans, no orthologues or paralogues for ENaC have been found in the genome databases of teleo...
متن کاملAnatomy and Histology of the Spiral Valve Intestine in Juvenile Australian Lungfish, Neoceratodus forsteri
The Australian lungfish, Neoceratodus forsteri, is the only vertebrate that possesses a complete spiral valve intestine with pre-pyloric coiling. This study describes the anatomy and histology of the spiral valve intestine in juvenile N. forsteri and compares it to a previous study of adult N. forsteri, thus providing a broader picture and better understanding of the intestine of the Australian...
