Brain - Endocast Relationship in the Australian Lungfish, Neoceratodus forsteri, Elucidated from Tomographic Data (Sarcopterygii: Dipnoi). [PDF]

PLoS ONE, 2015
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.

Respiratory control in the lungfish, Neoceratodus forsteri (krefft) [PDF]

Comparative Biochemistry and Physiology, 1967
1. Respiratory control has been studied in the lungfish, Neoceratodus forsteri by measuring ventilation (Ve), oxygen uptake (VO2), per cent O2 extraction from water, breathing rates of branchial and aerial respiration and changes in blood gas and pulmonary gas composition during exposure to hypoxia and hypercarbia. 2.

Notas sobre el esqueleto de los Peces Neoceratodus Fosteri y Protopterus Annectens Notas sobre el esqueleto de los Peces Neoceratodus Fosteri y Protopterus Annectens [PDF]

Caldasia, 1977
We present here a new description and drawings of the axial skeleton of Neoceratodus fosteri and Protopterus annectens. We discuss the differences between modern and fossil forms of lung fishes in reference to the formation of vertebrae in fossil forms ...

A Metapopulation Model to Assess Water Management Impacts on the Threatened Australian Lungfish, Neoceratodus forsteri

Fishes
The Australian lungfish, Neoceratodus forsteri, is one of the world’s oldest vertebrate lineages, with a slow life-history and threatened status, requiring immediate conservation efforts.

Physiological responses to prolonged aquatic hypoxia in the Queensland lungfish Neoceratodus forsteri [PDF]

Respiratory Physiology & Neurobiology, 2002
The effects of moderate and severe hypoxia on air breathing frequency and respiratory properties of the blood of the Queensland (Australian) lungfish Neoceratodus forsteri were measured in fish exposed to these conditions for 14-22 days at 20 degrees C.

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

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

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.

“Living fossils” and the mosaic evolution of characters

Frontiers in Ecology and Evolution, 2023
The modern discussion of living fossils turns mostly on the persistence of archaic, or ancestral, traits in extant organisms. Prime examples mentioned by Darwin already—who also coined the term “living fossil”—include the platypus and the extant ...

Phylogenomics Based on Transcriptome Data Provides Evidence for the Internal Phylogenetic Relationships and Potential Terrestrial Evolutionary Genes of Lungfish

Frontiers in Marine Science, 2021
The evolutionary relationships of lungfish can provide crucial information on the transition from Sarcopterygii to tetrapods. Phylogenomics is necessary to explore accurate internal phylogenetic relationships among all lungfish species. In the context of
