Parvalbumins from the lungfish (Protopterus dolloi) [PDF]
Biochimie, 1979 Five parvalbumins have been isolated from the white muscles of the lungfish. They can be divided into two sub families showing typical amino acid compositions, C-terminal amino acid residues, peptide maps and immuno-reactivity. The red muscles including the cardiac muscle also contain parvalbumins in amounts roughly inversely related to the ...

Respiratory Control in the Lungfish, Neoceratodus Forsteri (Krefft) [PDF]
, 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 ...

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.

A high latitude Devonian lungfish, from the Famennian of South Africa [PDF]
PeerJ, 2019 New fossil lungfish remains comprising two parasphenoids, tooth plates and scales from the Famennian Witpoort Formation of South Africa are described. From the parasphenoid material, which bears similarity to Oervigia and Sagenodus but is nevertheless ...

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 ...
