Anomalies in skull bones of the Australian lungfish,Neoceratodus forsteri, compared with aberrations in fossil dipnoan skulls

Journal of Vertebrate Paleontology, 1999
Abnormalities that appear during the development of the dermal, chondral and visceral cranium of the Australian lungfish, Neoceratodus forsteri, are common and many of these anomalies are reflected in the skulls of fossil lungfish.

Anatomy and cytology of the thymus in juvenile Australian lungfish, Neoceratodus forsteri

Journal of Anatomy, 2007
AbstractThe anatomy, histology and ultrastructure of the thymus of a dipnoan, the Australian lungfish, Neoceratodus forsteri, was studied by light and transmission electron microscopy. The thymic tissue showed clear demarcation into a cortex and medulla with ample vascularization. Large cells including foamy and giant multinucleated cells with periodic

Cephalic muscle development in the Australian lungfish,Neoceratodus forsteri

Journal of Morphology, 2017
AbstractLungfishes are the extant sister group of tetrapods. As such, they are important for the study of evolutionary processes involved in the water to land transition of vertebrates. The evolution of a true neck, that is, the complete separation of the pectoral girdle from the cranium, is one of the most intriguing morphological transitions known ...

Effects of environmental oxygen on development and respiration of Australian lungfish (Neoceratodus forsteri) embryos

Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 2011
The effects of oxygen partial pressure ([Formula: see text]) on development and respiration were investigated in the eggs of the Australian lungfish, Neoceratodus forsteri.

The energy cost of embryonic development in fishes and amphibians, with emphasis on new data from the Australian lungfish, Neoceratodus forsteri

Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 2010
The rate of oxygen consumption throughout embryonic development is used to indirectly determine the ‘cost’ of development, which includes both differentiation and growth.

Unravelling the mystery of endemic versus translocated populations of the endangered Australian lungfish (Neoceratodus forsteri)

Molecular Ecology, Volume 33, Issue 5, March 2024.
The Australian lungfish is a primitive and endangered representative of the subclass Dipnoi. The distribution of this species is limited to south-east Queensland, with some populations considered endemic and others possibly descending from translocations

Cellular ultrastructure and catecholamine histofluorescence of the heart of the Australian lungfish, Neoceratodus forsteri

Journal of Morphology, 1995
AbstractUltrastructural descriptions of the dipnoan heart are lacking. Many ultrastructural features of the heart of the Australian lungfish, Neoceratodus forsteri, resemble those of other lower vertebrates. The epicardial cells appear to be adapated for the exchange of material with the pericardial fluid. The most prominent features of the endocardial

Nonlethal, Epigenetic Age Estimation in a Freshwater Sportfish, Florida Bass (<i>Micropterus salmoides</i>). [PDF]

Ecol Evol
The conservation and management of black bass fisheries rely on the generation of age data to estimate population dynamics, and the development of an accurate, nonlethal age estimation method would expand opportunities for collecting age‐related information in cases where sacrificing fish is either not an option or undesirable.

Development of the Pectoral Lobed Fin in the Australian Lungfish Neoceratodus forsteri

Frontiers in Ecology and Evolution, 2021
The evolutionary transition from paired fins to limbs involved the establishment of a set of limb muscles as an evolutionary novelty. In parallel, there was a change in the topography of the spinal nerves innervating appendicular muscles, so that ...

Tell Us a Story Granddad: Age and Origin of an Iconic Australian Lungfish

Frontiers in Environmental Science, 2022
The modern discovery of the Australian lungfish (Neoceratodus forsteri) by European settlers in 1870 was considered one of the most important events in natural history by leading international scientists and naturalists of that time.
