Immunolocalization of Some Epidermal Proteins and Glycoproteins in the Growing Skin of the Australian Lungfish (Neoceratodus forsteri) [PDF]

open access: yesJournal of Developmental Biology, 2023
Here we report the immunolocalization of mucin, nestin, elastin and three glycoproteins involved in tissue mineralization in small and large juveniles of Neoceratodus forsteri.

Mandibular musculature constrains brain–endocast disparity between sarcopterygians [PDF]

open access: yesRoyal Society Open Science, 2020
The transition from water to land by the earliest tetrapods in the Devonian Period is seen as one of the greatest steps in evolution. However, little is understood concerning changes in brain morphology over this transition.

Cloning of nine glucocorticoid receptor isoforms from the slender African lungfish (Protopterus dolloi) [PDF]

open access: yesPLoS ONE, 2022
We wanted to clone the glucocorticoid receptor (GR) from slender African lungfish (Protopterus dolloi) for comparison to the P. dolloi mineralocorticoid receptor (MR), which we had cloned and were characterizing, as well as for comparison to the GRs from

Increased scalability and sequencing quality of an epigenetic age prediction assay. [PDF]

open access: yesPLoS ONE
Epigenetic ageing in a human context, has been used to better understand the relationship between age and factors such as lifestyle and genetics. In an ecological setting, it has been used to predict the age of individual animals for wildlife management.

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

open access: yesFrontiers 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 ...

A new method for reconstructing brain morphology: applying the brain-neurocranial spatial relationship in an extant lungfish to a fossil endocast [PDF]

open access: yesRoyal Society Open Science, 2016
Lungfish first appeared in the geological record over 410 million years ago and are the closest living group of fish to the tetrapods. Palaeoneurological investigations into the group show that unlike numerous other fishes—but more similar to those in ...

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

open access: yesPLoS 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.

“Living fossils” and the mosaic evolution of characters

open access: yesFrontiers 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

open access: yesFrontiers 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

Lungfish and the Long Defeat

open access: yesDiversity, 2023
Australia has an excellent fossil record of lungfish that begins in the Devonian and includes many species in Tertiary and Quaternary deposits. The extant Australian lungfish, Neoceratodus forsteri, occurs in Pliocene deposits, but is now restricted to a
