Extirpation of Lake Sturgeon in an Ontario Lake Following Dam Construction and Watershed Diversion Confirmed by Indigenous Traditional Knowledge and Sedimentary eDNA. [PDF]

Ecol Evol
Local Anishinaabe communities, Long Lake #58 and Ginoogaming, long emphasized the many negative consequences for the environment and non‐human kin caused by the Upper Kenogami diversion, including the local extirpation of lake sturgeon from Long Lake.

Utilizing Environmental DNA Metabarcoding to Assess Fish‐Based Food Resources in Key Foraging Areas of the Black Stork [PDF]

Ecol Evol
This study employed environmental DNA (eDNA) to assess fish‐based food resources in key foraging areas of the Black Stork (Ciconia nigra)—Zhanghe Canyon and Qixi River National Wetland Parks in Henan, China. Results show that the main prey in these habitats are fish from the orders Siluriformes, Cypriniformes, and Perciformes, with no significant ...

Identification and characterization of hybrids of Acipenser ruthenus and Acipenser baerii (Actinopterygii, Acipenseriformes) from the Irtysh River [PDF]

Acta Biologica Sibirica, 2021
Two sturgeon species, Acipenser ruthenus (Linnaeus, 1758) and Acipenser baerii (Brandt, 1869), inhabit the Irtysh basin. In 2018, we received some “atypical” specimens of sturgeon, which were similar to A. ruthenus but had a number of pronounced external

The karyotype of the Amu Darya sturgeon, Pseudoscaphirhynchus kaufmanni (Actinopterygii: Acipenseriformes: Acipenseridae) [PDF]

Acta Ichthyologica et Piscatoria, 2014
Background. Karyological studies of acipenserid fishes are of great importance because they present the only direct method to evaluate their ploidy levels for further research on polyploid evolution in these fishes. They are also important for prediction

Evolutionary process of a tetranucleotide microsatellite locus in Acipenseriformes [PDF]

Journal of Genetics, 2011
The evolutionary dynamics of the tetra-nucleotide microsatellite locus Spl-106 were investigated at the repeat and flanking sequences in 137 individuals of 15 Acipenseriform species, giving 93 homologous sequences, which were detected in 11 out of 15 species.

Patterns and Processes of Genomic Evolution Inferred From the Ten Smallest Vertebrate Genomes. [PDF]

Adv Sci (Weinh)
By integrating phylogenetic relationships derived from nuclear DNA with population genetic analyses across ten pufferfish species, the genetic differentiation mechanisms underpinning the radiative speciation of the most compact vertebrate genomes has elucidated.

A Multistep DNA-Based Methodology for Accurate Authentication of Sturgeon Species

Foods, 2022
The sturgeons (order Acipenseriformes) are caviar producers and some of the most valuable fish species worldwide. Due to different reasons, wild populations are now at the brink of extinction.

Marking fin spine of juvenile sturgeon (acipenseriformes: acipenseridae) using oxytetracycline and the comparing of growth performance

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2021
This study aimed to describe and validate the formation of the rings in the spine of the pectoral fin and to determine the coherence of the OTC mark with the rings of three species of Caspian Sea sturgeon, the Persian sturgeon (Acipenser persicus), the ...

Molecular cytogenetic differentiation of paralogs of Hox paralogs in duplicated and re-diploidized genome of the North American paddlefish (Polyodon spathula). [PDF]

, 2017
BackgroundAcipenseriformes is a basal lineage of ray-finned fishes and comprise 27 extant species of sturgeons and paddlefishes. They are characterized by several specific genomic features as broad ploidy variation, high chromosome numbers, presence of ...
