The 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 کاملDevelopment 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 کاملThe trophic link between squid and the emperor penguin Aptenodytes forsteri at Pointe Géologie, Antarctica
Cephalopod beaks retrieved from stomachs of dead emperor penguin chicks at Pointe Géologie, Terre Adélie, provide information on taxonomic and size composition of the penguin’s squid diet, on the trophic range of the squid species preyed upon and on the fractional trophic impact of the penguin on the whole food web. Emperor penguins prey upon four squid species (Psychroteuthis glacialis, Kondak...
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...
