Visual ecology of the Australian lungfish (Neoceratodus forsteri) [PDF]

BMC Ecology, 2008
Background The transition from water to land was a key event in the evolution of vertebrates that occurred over a period of 15–20 million years towards the end of the Devonian. Tetrapods, including all land-living vertebrates, are thought to have evolved

Age structure of the Australian lungfish (Neoceratodus forsteri).

PLoS ONE, 2019
The Australian lungfish has been studied for more than a century without any knowledge of the longevity of the species. Traditional methods for ageing fish, such as analysis of otolith (ear stone) rings is complicated in that lungfish otoliths differ ...

Visual pigments in a living fossil, the Australian lungfish Neoceratodus forsteri [PDF]

BMC Evolutionary Biology, 2007
Background One of the greatest challenges facing the early land vertebrates was the need to effectively interpret a terrestrial environment. Interpretation was based on ocular adaptations evolved for an aquatic environment millions of years earlier.

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

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 ...

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.

Biological clocks as age estimation markers in animals: a systematic review and meta‐analysis

Biological Reviews, Volume 98, Issue 6, Page 1972-2011, December 2023., 2023
ABSTRACT Various biological attributes associated with individual fitness in animals change predictably over the lifespan of an organism. Therefore, the study of animal ecology and the work of conservationists frequently relies upon the ability to assign animals to functionally relevant age classes to model population fitness.

Exploring chromosome evolution in 250 million year old groups of dragonflies and damselflies (Insecta:Odonata)

Molecular Ecology, Volume 32, Issue 21, Page 5785-5797, November 2023., 2023
Abstract Using recently published chromosome‐length genome assemblies of two damselfly species, Ischnura elegans and Platycnemis pennipes, and two dragonfly species, Pantala flavescens and Tanypteryx hageni, we demonstrate that the autosomes of Odonata have undergone few fission, fusion, or inversion events, despite 250 million years of separation.

People need freshwater biodiversity

WIREs Water, Volume 10, Issue 3, May/June 2023., 2023
Freshwater biodiversity (i.e., plants, animals, fungi, microbes, and other living things) provides a suite of critical ecosystem services to people. Collapses in freshwater biodiversity impact people, across all regions of the globe, rural–urban gradients, and the full socioeconomic spectrum, but perhaps most particularly indigenous and marginalized ...

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.

Plastic loss of motile cilia in the gills of Polypterus in response to high CO2 or terrestrial environments

Ecology and Evolution, Volume 13, Issue 4, April 2023., 2023
The major changes in animal respiratory systems during the transition of vertebrates from water to land is one of the primary interests in evolutionary biology. We demonstrated the existence of motile cilia that produce water flows on the surface of the gills of Polypterus, an amphibious fish.
