Conservation Genetics Resources, 2013 We isolated and characterized 21 microsatellite loci in the vulnerable and iconic Australian lungfish, Neoceratodus forsteri. Loci were screened across eight individuals from the Burnett River and 40 individuals from the Pine River. Genetic diversity was

Acta Zoologica, 2009 The apical ectodermal ridge (AER) in Neoceratodus develops after an initial period of mesenchymal proliferation and outgrowth of the fin bud and persists until chondrogenesis of the stylopod and zeugopod is initiated. At this time, the lateral margins of

Homeobox genes in the Australian lungfish,Neoceratodus forsteri
Journal of Experimental Zoology, 1999The aim of the present study was to determine whether the postulated gnathostome duplication from four to eight Hox clusters occurred before or after the split between the actinopterygian and sarcopterygian fish by characterizing Hox genes from the sarcopterygian lungfish, Neoceratodus forsteri.

The adenohypophysis of the Australian lungfish, Neoceratodus forsteri—An immunocytological study
General and Comparative Endocrinology, 1990The cell types in the adenohypophysis of Neoceratodus resemble closely those already described for Lepidosiren and Protopterus. Four of these were immunocytochemically identified as prolactin cells, gonadotropes, corticotropes, and melanotropes. Antiserum to bullfrog growth hormone could not distinguish between prolactin cells and somatotropes.

Ultrastructure of the integumental melanophores of the Australian lungfish, Neoceratodus forsteri
Cell and Tissue Research, 1975The integumental melanophores of Australina lungfish, Neoceratodus forsteri, were examined by light and electron microscopy and found to possess essentially the same structural characteristics observed in other vertebrates. The epidermal melanophores are located in the intermediate epidermis and possess round perikarya and slender dendrites extending ...

Ciliary cells in the epidermis of the larval Australian dipnoan, Neoceratodus
Zoological Journal of the Linnean Society, 1980Newly hatched Australian lungfish, Neoceratodus forsteri KrefFt, develop a ciliary current over the skin surface which continues for more than six weeks of larval life. The gill surface under the opercula also becomes ciliated. The ciliary cells producing the current are found to develop in like manner to those in several amphibian embryos and larvae ...

Teleost-Type Angiotensin Is Present in Australian Lungfish,Neoceratodus forsteri
General and Comparative Endocrinology, 1999Angiotensin I (ANG I) was produced from the incubation of lungfish plasma with homologous kidney extracts. The purified peptide was found to have the sequence of H-Asn-Arg-Val-Tyr-Val-His-Pro-Phe-Thr-Leu-OH, which is homologous for the first eight residues with all teleost angiotensins so far sequenced, although lungfish generally possess tetrapod-type

Vascularization of the pituitary of the Australian lungfish and Neoceratodus forsteri
Acta Zoologica, 1999The vascularization of the brain and the pituitary region of the Australian lungfish, Neoceratodus forsteri is described from serial section reconstruction. The distal lobe has no direct arterial blood supply and receives blood solely from a pituitary portal system basically similar to that of other sarcopterygians.

The Australian lungfish, Neoceratodus forsteri: A personal story
General and Comparative Endocrinology, 2011The following is a brief description of how lungfish research at Macquarie University began, of the period in which it flourished, and, most recently, of the winding down of the University's involvement with this research. During this latter period, the Australian lungfish in the wild were threatened by the construction of a megadam in their very ...
