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.

Lungfish and the Long Defeat

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

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 ...

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.

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.

How big can a walking fish be? A theoretical inference based on observations on four land‐dwelling fish genera of South Vietnam

Integrative Zoology, Volume 17, Issue 5, Page 849-878, September 2022., 2022
Modern amphibiotic fishes use various walking techniques but are smaller in length than half a meter, whereas extinct tetrapodomorph fishes of Devonian ranged from 0.5 to 2.5 m. Could they walk out of water, and how did they walk if they could? This study argues that, in recent ichthyofauna, snakehead is most appropriate for modeling walking technique ...

Whole‐body endothermy: ancient, homologous and widespread among the ancestors of mammals, birds and crocodylians

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.

Expression of meis and hoxa11 in dipnoan and teleost fins provides new insights into the evolution of vertebrate appendages

EvoDevo, 2018
Background The concerted activity of Meis and Hoxa11 transcription factors is essential for the subdivision of tetrapod limbs into proximo-distal (PD) domains; however, little is know about the evolution of this patterning mechanism.

The conundrum of pharyngeal teeth origin: the role of germ layers, pouches, and gill slits

Biological Reviews, Volume 97, Issue 1, Page 414-447, February 2022., 2022
ABSTRACT There are several competing hypotheses on tooth origins, with discussions eventually settling in favour of an ‘outside‐in’ scenario, in which internal odontodes (teeth) derived from external odontodes (skin denticles) in jawless vertebrates. The evolution of oral teeth from skin denticles can be intuitively understood from their location at ...
