Re‐make, re‐model: evolution and development of vertebrate cranial lateral lines

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2237-2256, December 2025.
ABSTRACT Lateral lines are placodally derived mechanosensory systems on the heads and trunks of many aquatic vertebrates. There is evidence of lateral lines in the earliest known vertebrate fossils, and they exist in organisms with widely different craniofacial morphologies – including the presence or absence of jaws, external or internal nostrils, and

The South American lungfish Lepidosiren paradoxa as a new host for Trichodina quelenii

open access: yesBrazilian Journal of Biology, 2018
Recently, the South American lungfish Lepidosiren paradoxa is being found inside aquaculture ponds, and even though there are a few studies on their parasite fauna, there is still much to be reported.

Nonlethal, Epigenetic Age Estimation in a Freshwater Sportfish, Florida Bass (Micropterus salmoides)

open access: yesEcology and Evolution, Volume 15, Issue 11, November 2025.
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.

Linkage Mapping vs. Association: A Comparison of Two RADseq‐Based Approaches to Identify Markers for Homomorphic Sex Chromosomes in Large Genomes

open access: yesMolecular Ecology Resources, Volume 25, Issue 7, October 2025.
ABSTRACT Reliable tools for the identification of genetic sex are invaluable in many fields of biology, but their design requires knowledge of sex‐linked sequences, which is lacking in many taxa. Restriction‐site‐associated DNA sequencing (RADseq) is widely used to identify sex‐linked markers, but multiple distinct strategies are employed, and it is ...

Retinal projections in the australian lungfish [PDF]

open access: yesBrain Research, 1980
Autoradiographic analysis of the primary retinofugal projections in the Australian lungfish reveals contralateral retinal projections to a ventral portion of the periventricular preoptic nucleus, throughout its rostrocaudal extent, and to 4 distinct terminal fields in the thalamus. Only one of these thalamic fields (t4) likely receives dendrites solely

Analysis of the African coelacanth genome sheds light on tetrapod evolution [PDF]

open access: yes, 2014
It was a zoological sensation when a living specimen of the coelacanth was first discovered in 1938, as this lineage of lobe-finned fish was thought to have gone extinct 70 million years ago.

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

open access: yesAnimal 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

Afterberners: An Assemblage of Nouns [PDF]

open access: yes, 1991
The English language owes a debt of gratitude of Dame Juliana Berners. She was born circa 1388 and is believed to have been the prioress of a nunnery near St. Albans, Hertforshire, England.

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

open access: yesJournal 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
