Comparative pelvic development of the axolotl (Ambystoma mexicanum) and the Australian lungfish (Neoceratodus forsteri) : conservation and innovation across the fish-tetrapod transition [PDF]

, 2013
Background: The fish-tetrapod transition was one of the major events in vertebrate evolution and was enabled by many morphological changes. Although the transformation of paired fish fins into tetrapod limbs has been a major topic of study in recent ...

Habitat Quality and Water Availability Affect Genetic Connectivity of Platypus Across an Urban Landscape

Animal Conservation, Volume 28, Issue 5, Page 648-662, October 2025.
We developed a set of innovative landscape resistance models to identify how climatic, topographic and vegetation variables influenced gene flow in the iconic Australian platypus across a 300 km2 urbanised landscape. Our research identified topographic wetness, rainfall and vegetation cover as consistently important for maintaining landscape‐scale gene

High resolution transmission electron microscopy of developing enamel in the Australian lungfish, Neoceratodus forsteri (Osteichthyes:Dipnoi)

, 2007
The permanent tooth plates of the Australian lungfish, Neoceratodus forsteri, are covered by enamel that develops initially in a similar manner to that of other vertebrates. As the enamel layer matures, it acquires several unusual characteristics. It has

Surface Topography and Ultrastructure of the Spectacular Cells in the Eyes of Land and Sea Snakes (Squamata, Reptilia): Functional Adaptations of Micro‐Ornamentation

Journal of Morphology, Volume 286, Issue 9, September 2025.
ABSTRACT Although the surface micro‐ornamentation of the scales within the skin of snakes has been the subject of many previous studies, there has been little work done on the spectacle, a protective (keratinised) goggle separated from the underlying cornea by a sub‐spectacular space. The surface ultrastructure of the “Oberhäutchen” of the spectacle is

Comparative Analysis of Nkx2.1 and Islet-1 Expression in Urodele Amphibians and Lungfishes Highlights the Pattern of Forebrain Organization in Early Tetrapods

Frontiers in Neuroanatomy, 2018
Expression patterns of Nkx2.1 and Islet-1 (Isl1), which encode transcription factors that are key in the regionalization of the forebrain, were analyzed by combined immunohistochemical methods in young adult specimens of two lungfishes (Neoceratodus ...

Revisiting the History of Ornamental Aquaculture in Europe to Understand the Benefits and Drawbacks of Freshwater Fish Imports

Reviews in Aquaculture, Volume 17, Issue 2, March 2025.
ABSTRACT Ornamental aquaculture and fishkeeping are very popular with millions of enthusiasts worldwide. The number of newly imported fish species for ornamental purposes grew slowly from World War I until the 1980s. It then exponentially increased until now with more than 7900 species and a large number of scientifically undescribed morphotypes.

Anatomical insights into fish terrestrial locomotion: A study of barred mudskipper (Periophthalmus argentilineatus) fins based on μCT 3D reconstructions

Journal of Anatomy, Volume 245, Issue 4, Page 593-624, October 2024.
This study reveals that the barred mudskipper, Periophthalmus argentilineatus, has evolved intricate musculoskeletal features in its fins, such as increased muscle volume, skeletal reinforcements, and specialized aponeuroses, signifying a profound evolutionary shift toward terrestrial life.

Pitfalls and windfalls of detecting demographic declines using population genetics in long‐lived species

Evolutionary Applications, Volume 17, Issue 7, July 2024.
Abstract Detecting recent demographic changes is a crucial component of species conservation and management, as many natural populations face declines due to anthropogenic habitat alteration and climate change. Genetic methods allow researchers to detect changes in effective population size (Ne) from sampling at a single timepoint.

Extremely low microsatellite diversity but distinct population structure in a long-lived threatened species, the Australian lungfish Neoceratodus forsteri (Dipnoi).

PLoS ONE, 2015
The Australian lungfish is a unique living representative of an ancient dipnoan lineage, listed as 'vulnerable' to extinction under Australia's Environment Protection and Biodiversity Conservation Act 1999.
