Studies on the queensland lungfish, neoceratodus forsteri (Krefft) ii. thermal acclimation [PDF]
, 1964 Six juvenile Neoceratodus of convenient size for respirometry (27–51 g) were available for study. Fish of this size are very rarely taken and the opportunity was used to examine the ability of Neoceratodus to undergo metabolic acclimation. Metabolic rate-temperature curves were constructed for fish with cold (18°C) and warm (25°C) thermal histories ...

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

Diversity, 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

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates. [PDF]
Biol Rev Camb Philos SocABSTRACT 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 ...

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.

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 ...

Tetrachromatic colour vision in the Australian lungfish Neoceratodus forsteri
, 2006 The visual system of the Australian lungfish N. forsteri has more in common with terrestrial vertebrates such as reptiles and birds, than with both sharks and bony fish. Features such as coloured oil droplets and multiple visual pigments indicate their phylogenetic allegiance with tetrapods, and suggest that the terrestrial trend for colour vision on ...

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.

Biological Reviews, Volume 97, Issue 2, Page 766-801, April 2022., 2022 ABSTRACT The whole‐body (tachymetabolic) endothermy seen in modern birds and mammals is long held to have evolved independently in each group, a reasonable assumption when it was believed that its earliest appearances in birds and mammals arose many millions of years apart.
