A Comment on the Siberian, Acipenser baerii, and Russian, Acipenser gueldenstaedtii, Sturgeons [PDF]

Environmental Biology of Fishes, 2004
Contrary to the opinion of Kynard et al. (2002), the Siberian sturgeon, Acipenser baerii, does not belong to the Ponto-Caspian species. It inhabits Siberian rivers and Lake Baikal. Acipenser baerii is a typical potamodromous species and the comparison of the behavior of its embryos and larvae with those of the anadromous Russian sturgeon, Acipenser ...

Atlantic sturgeons (Acipenser sturio, Acipenser oxyrinchus): American females successful in Europe [PDF]

Naturwissenschaften, 2006
Recent molecular data on the maternally inherited mitochondrial (mt) DNA have challenged the traditional view that the now extinct Baltic sturgeon population belonged to the European sturgeon Acipenser sturio. Instead, there is evidence that American sea sturgeon Acipenser oxyrinchus historically immigrated into the Baltic Sea.

Acipenser sturioandAcipenser nudiventrisin the Danube - extant or extinct? [PDF]

Journal of Applied Ichthyology, 2009
Summary The presence of Atlantic sturgeon (Acipenser sturio) and ship sturgeon (Acipenser nudiventris) in the Danube has been known through only occasional, chance sightings; significant uncertainty remains as to whether these species are already extinct or still present in the Danube River basin.

The complete mitochondrial genome of the Acipenser schrenckii (Acipenseridae: Acipenser)

Mitochondrial DNA, 2013
The Acipenser schrenckii is an ancient freshwater Chondrostei species, which is mainly distributed in Amur River in China and Russian. The complete mitochondrial genome of A. schrenckii was obtained for the first time in this study. The circular genome (16,548 bp in length) consists of 37 typical animal mitochondrial genes (13 protein-coding genes, 22 ...

Palaeogenetics of western French sturgeons spotlights the relationships between Acipenser sturio and Acipenser oxyrinchus

Journal of Biogeography, 2012
AbstractAimThe Atlantic sturgeon, Acipenser oxyrinchus, was long considered an American species, but recent discoveries based on analyses of archaeological remains proved its presence in the Baltic Sea and in France. This came as a surprise, as the European sturgeon, Acipenser sturio, was thought to be the only sturgeon species present on the European ...

Biochemical Characterization of Hemoglobins from Caspian Sea Sturgeons (Acipenser persicus and Acipenser stellatus)

Cell Biochemistry and Biophysics, 2011
Hemoglobin (Hb) variability is a commonly used index of phylogenetic differentiation and molecular adaptation in fish enabling them to adapt to different ecological conditions. In this study, the characteristics of Hbs from two Sturgeon species of the Southern Caspian Sea Basin were investigated. After extraction and separation of hemoglobin from whole

Serum biochemical parameters of Acipenser persicus

Fish Physiology and Biochemistry, 2006
Serum biochemical parameters are important aspects in the management of endangered species, such as Acipenser persicus. The values of these parameters can be used for confirming the maturity and for monitoring any changes in the quality of waters and related soils. Serum samples of 44 A.

Neurohypophysial hormones as molecular evolutionary tracers: investigations on the sturgeons Acipenser stellatus and Acipenser guldenstadti

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1991
Abstract 1. 1. Neurohypophysial hormones of two sturgeon species, Acipenser stellatus and Acipenser guldenstadti , have been purified through molecular sieving on Bio-Gel P4 and reverse-phase high pressure liquid chromatography on Nucleosil C18 columns. 2. 2.
