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

Permanent germinal epithelium and reproductive cycle of tropical gar Atractosteus tropicus males (Lepisosteiformes: Lepisosteidae), Tabasco, Mexico

Revista de Biología Tropical, 2016
Tropical gar A. tropicus plays an important ecological role, as a regulator of other fish stocks, in the water bodies of Mexico but their wild populations are being reduced. One conservation alternative is breeding which requires the study of germ and somatic structures of testis to characterize the reproductive cycle, basic knowledge required to ...

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.

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.

Comments on the cranial and pectoral girdle osteology of Lepidotes gigas (Actinopterygii, Lepisosteiformes) from the Lower Jurassic (lower Toarcian) of Germany

Journal of Vertebrate Paleontology, 2023
A transfer-prepared specimen of Lepidotes (Actinopterygii, Lepisosteiformes) from the Posidonia Shale Formation of south Germany is tentatively identified specifically as L. gigas. The genus and its species are insufficiently defined and in need of revision.

Correct size of the Late Jurassic freshwater fish, Beiduyu qijiangensis (Ginglymodi, Lepisosteiformes) from Qijiang, Chongqing, China [PDF]

Journal of Vertebrate Paleontology, 2015
In our recent description of the Jurassic ginglymodian fish Beiduyu qijiangensis (Murray et al., 2015) we misinterpreted the scale bar included with the photographs, which resulted in reporting the...

Evidence of very low genetic diversity of cuban gar (Atractosteus tristoechus)/ Evidencia de pobre diversidad genética del manjuarí (Atractosteus tristoechus)

Revista de Investigaciones Marinas, 2016
The Cuban gar (Atractosteus tristoechus) is an endemic freshwater fish species of Cuba. Among the Lepisosteiformes, this species is one of the most threatened and has the lowest natural distribution range.

Form and function of anguilliform swimming

Biological Reviews, Volume 99, Issue 6, Page 2190-2210, December 2024.
ABSTRACT Anguilliform swimmers are long and narrow animals that propel themselves by undulating their bodies. Observations in nature and recent investigations suggest that anguilliform swimming is highly efficient. However, understanding the underlying reasons for the efficiency of this type of locomotion requires interdisciplinary studies spanning ...
