Two Paralogues as They Like It: Conserved and Divergent Evolution of Vertebrate Gcm Genes
Evolution &Development, Volume 28, Issue 3, September 2026.Comparative overview of Gcm1 and Gcm2 paralogues across vertebrates. Gcm2 is conserved in pharyngeal‐derived organs across gnathostomes, whereas Gcm1 shows lineage‐specific diversification from an ancestral pharyngeal context, including secondary loss in teleosts, distinct expression in bichir gills and skin, and broader expression in mammals ...

Fish Sperm Subpopulations Detection, Separation, and Application: Current State and Trends
Reviews in Aquaculture, Volume 18, Issue 4, September 2026.Modern advances in sperm biology highlight the necessity of recognising intra‐ejaculate heterogeneity as a central concept for advancing both the fundamental understanding of fertilisation processes and the development of artificial reproduction techniques in fishes. ABSTRACT Sperm subpopulations represent a fundamental manifestation of intra‐ejaculate

Journal of Comparative Neurology, Volume 534, Issue 8, August 2026.Sturgeons are an ancient and basal group of ray‐finned fishes whose pallium consists of lateral, medial, and posterior divisions. The connections of these divisions were determined by injections of biotinylated dextran amine and DiI. Although there is considerable overlap in the connections of these pallial divisions, their heaviest connections are ...

Nitrogenous compounds and oxygen concentration as the key density dependent factors to optimize growth of beluga, Huso huso (Actinopterygii: Acipenseriformes: Acipenseridae), in circular fiberglass tanks [PDF]
Acta Ichthyologica et Piscatoria, 2011 Background. Beluga, Huso huso, known also as the great sturgeon, is a valuable fish in terms of meat and caviar production. It has been implicated that intensive fish culture is a major culprit for deterioration of water quality through metabolic ...

Bony fish genomes: Status and gaps
Journal of Fish Biology, Volume 109, Issue 2, Page 631-649, August 2026.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.

A Comparative Analysis of Life History and Alimentary Canal Morphology and Physiology in Elasmobranchii and Acipenseriformes [PDF]
, 2009 Elasmobranchii and Acipenseriformes are two ancient, yet highly derived groups of cartilaginous fishes with trophic dynamics ranging from planktivore to carnivore, habitat distributions ranging from the northern hemisphere to circumglobal, and widely ...

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
