Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

Developmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Global Patterns and Gaps in Research on Salinity Tolerance of Inland Fishes

Fish and Fisheries, Volume 27, Issue 2, Page 400-411, March 2026.
ABSTRACT Freshwater salinization is an emerging threat impacting approximately one‐third of the world's freshwater bodies. However, the salinity tolerance of many inland fishes remains understudied, despite being a crucial factor in determining species distributions and fitness.

Different evolutionary patterns of hypoxia‐inducible factor α (HIF‐α) isoforms in the basal branches of Actinopterygii and Sarcopterygii

FEBS Open Bio, Volume 3, Issue 1, Page 479-483, January 01, 2013., 2013
Hypoxia‐inducible factor (HIF) is a crucial regulator of cellular and systemic responses to low oxygen levels. Here we firstly cloned three HIF‐α isoforms from the basal branches of Osteichthyes and used computational tools to characterise the molecular change underlying the functional divergence of HIF‐α isoforms in different lineages. Only the HIF‐1α

A new genus and species for the amiiform fishes previously assigned to Amiopsis from the Early Cretaceous of Las Hoyas, Cuenca, Spain [PDF]

, 2017
The Mesozoic actinopterygian fish Amiopsis has been reported from three different localities in the Iberian Peninsula. Amiopsis woodwardi was described from the Berriasian–Valanginian of El Montsec (Lérida, Spain).

A new Lepisosteiformes (Actinopterygii: Ginglymodi) from the Early Cretaceous of Laos and Thailand, SE Asia

Journal of Systematic Palaeontology, 2018
A new genus and new species of ginglymodian is described from the Aptian Grès supérieurs Formation of the Savannakhet Basin, Laos (Lao People's Democratic Republic), found at the Ban Lamthouay locality. The fish is known from a single isolated head, which shows enough diagnostic characters to characterize a new taxon.

The oldest acanthomorph fossil (Actinopterygii, Teleostei) from the Early Cretaceous of Gondwana (Morro do Chaves Formation, Sergipe–Alagoas Basin, NE Brazil)

Papers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract This paper presents the discovery of †Gondwanacanthus decollatus, a new genus and species of Early Cretaceous deep‐bodied fish from the late Barremian or early Aptian Morro do Chaves Formation in the Sergipe–Alagoas Basin, northeastern Brazil. It represents the first record of Acanthomorpha in Early Cretaceous Gondwana.

Integrating multi-origin expression data improves the resolution of deep phylogeny of ray-finned fish (Actinopterygii) [PDF]

, 2012
The actinopterygians comprise nearly one-half of all extant vertebrate species and are very important for human well-being. However, the phylogenetic relationships among certain groups within the actinopterygians are still uncertain, and debates about ...

Fine‐Scale Bioregionalization in a Complex Island System: A Freshwater Perspective From the Greater Antilles

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim The isolated nature of islands makes them particularly vulnerable to climate change. The freshwater fishes of the Greater Antilles remain understudied and are further threatened by habitat fragmentation and the introduction of exotic invasive species.
