Evidence for a Slowed Rate of Molecular Evolution in the Order Acipenseriformes [PDF]
Molecular Biology and Evolution, 2002 A test of the hypothesis that the members of the order Acipenseriformes (sturgeons and paddlefishes) possess a slowed rate of molecular evolution was carried out by conducting relative-rate comparisons with representatives of four groups of teleost fishes (Cypriniformes, Elopomorpha, Salmonidae, and Percomorpha) using 21 nuclear or mitochondrial ...

Molecular analysis of phylogeographic subspecies in three Ponto-Caspian sturgeon species
Genetics and Molecular Biology, 2014 Sturgeons (Order Acipenseriformes) represent an extremely valuable natural resource that is now facing depletion. In the current study we evaluate if the traditional classification in subspecies of Acipenser gueldenstaedtii, Acipenser stellatus and Huso ...

Detection of white sturgeon iridovirus (WSIV) in sturgeons (Actinopterygii: Acipenseriformes: Acipenseridae) from aquaculture facilities located in Poland, Germany, and Italy [PDF]
Acta Ichthyologica et Piscatoria, 2019 Background. White sturgeon iridovirus (WSIV) is one of the most serious threats for sturgeon aquaculture as the mortality in juvenile individuals can reach 95%.

Moleсular-genetic markers in study of intra- and interspecific polymorphism of Acipenseriformes
, 2010 Uniqueness and high commercial value of relic group of sturgeon fishes stimulated researches of their genetic polymorphism. In the review the basic molekular-genetic markers used for an estimation of genetic variability are considered; their merits and ...

Efficient Gene Transfer and Gene Editing in Sterlet (Acipenser ruthenus)
Frontiers in Genetics, 2018 The sturgeon (Acipenseriformes) is an important farmed species because of its economical value. However, neither gene transfer nor gene editing techniques have been established in sturgeon for molecular breeding and gene functional study until now.

The effect of short-term starvation on some physiological and morphological parameters in juvenile Siberian sturgeon, Acipenser baerii (Actinopterygii: Acipenseriformes: Acipenseridae) [PDF]
Acta Ichthyologica et Piscatoria, 2013 Background. Fish may experience periods of food deprivation or starvation in nature and under culture conditions. Because of the wild  stock reduction of some sturgeon species, Siberian sturgeon, Acipenser baerii Brandt, 1869, has been used as a

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.

Journal of Morphology, Volume 287, Issue 10, October 2026.The pectoral fin spine (PFS) of the sturgeon is a robust dermal skeletal element that extends laterally and is located on the leading edge of the pectoral fin. The PFS is a load‐bearing dermal bone composed of peripheral parallel‐fibered bone and dermal osteonal bone organized around an interconnected neurovascular network.
