Brain Reconstruction Across the Fish-Tetrapod Transition; Insights From Modern Amphibians

Frontiers in Ecology and Evolution, 2021
The fish-tetrapod transition (which incorporates the related fin-limb and water-land transitions) is celebrated as one of the most important junctions in vertebrate evolution.

A Comparison of the Innate and Adaptive Immune Systems in Cartilaginous Fish, Ray-Finned Fish, and Lobe-Finned Fish

Frontiers in Immunology, 2019
The immune system is composed of two subsystems—the innate immune system and the adaptive immune system. The innate immune system is the first to respond to pathogens and does not retain memory of previous responses.

Prioritizing the reassessment of data‐deficient species on the IUCN Red List

Conservation Biology, Volume 37, Issue 6, December 2023., 2023
Abstract Despite being central to the implementation of conservation policies, the usefulness of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species is hampered by the 14% of species classified as data‐deficient (DD) because information to evaluate these species’ extinction risk was lacking when they were last ...

Linking geographic distribution and niche through estimation of niche density. [PDF]

J Anim Ecol
Species with larger climatic tolerances (niches) may have large or small geographic ranges, dependent on the commonness of favourable climatic conditions across geographic space. Here, we explore the relationship between geographic range size and niche area, while also proposing a novel measure of niche density.

Species which may act as vectors or reservoirs of diseases covered by the Animal Health Law: Listed pathogens of fish

EFSA Journal, Volume 21, Issue 8, August 2023., 2023
Abstract Vector or reservoir species of five fish diseases listed in the Animal Health Law were identified, based on evidence generated through an extensive literature review (ELR), to support a possible updating of Regulation (EU) 2018/1882. Fish species on or in which highly polymorphic region‐deleted infectious salmon anaemia virus (HPR∆ ISAV), Koi ...

A new vampyromorph species from the Middle Jurassic La Voulte‐sur‐Rhône Lagerstätte

Papers in Palaeontology, Volume 9, Issue 3, May/June 2023., 2023
Abstract Eight coleoid genera have so far been described from the Callovian‐aged La Voulte‐sur‐Rhône Lagerstätte (c. 165 Ma; Ardèche, France), a locality noted for its unique three‐dimensional preservation of soft tissues. Here, we used high resolution x‐ray‐based imaging methods, in conjunction with reflectance transformation imaging, to study the ...

Conservation of Intronic Sequences in Vertebrate Mitochondrial Solute Carrier Genes (Zebrafish, Chicken, Mouse and Human)

Non-Coding RNA, 2019
The conservation of intronic sequences was studied in the mitochondrial solute carrier (SLC25A*) genes of Zebrafish, Chicken, Mouse and Human. These genes are homologous and the coding sequences have been well conserved throughout Vertebrates, but the ...

The cranial endocast of the Upper Devonian dipnoan ‘Chirodipterus’ australis [PDF]

PeerJ, 2018
One of the first endocasts of a dipnoan (lungfish) to be realised was that of the Upper Devonian taxon Chirodipterus australis. This early interpretation was based on observations of the shape of the cranial cavity alone and was not based on a natural ...

The first Jurassic coelacanth from Switzerland

Swiss Journal of Palaeontology, 2022
Coelacanths form a clade of sarcopterygian fish represented today by a single genus, Latimeria. The fossil record of the group, which dates back to the Early Devonian, is sparse.
