Sibling-Derived Cell Lines of Whole Larval Siberian Sturgeon as an In Vitro Model System for Studying Inter-Individual Differences Within the Same Genomic Heritage [PDF]

Cells
Sturgeons, once resilient enough to outlive dinosaurs, are now critically endangered. All 26 species of Acipenseriformes face extinction due to anthropogenic causes.

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.

A global perspective of fragmentation on a declining taxon – the sturgeon (Acipenseriformes) [PDF]

Endangered Species Research, 2016
Acipenseriformes (sturgeons and paddlefishes) are considered to be one of the most globally imperiled taxon, with 25 of the 27 species listed by the International Union for the Conservation of Nature (IUCN).

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.

Environmental DNA Reveals the Fish Community Structure Exhibited Instability and Trend of Miniaturization in the Xijiang River Basin of the Guizhou. [PDF]

Ecol Evol
Monitoring of fish communities is of great significance for the management and sustainability of river ecosystems. Environmental DNA (eDNA) metabarcoding technology has been demonstrated to be a highly sensitive biomonitoring tool. Nevertheless, it has seldom been tested in mountainous rivers within the geographically complex Karst region.

Anatomical study of pericardioperitoneal canal in immature beluga (Huso huso) with ultrasonography. [PDF]

Vet Med Sci
In the present study on immature beluga, it was observed that the canal is located caudal to the sinus venosus and is caudoventral to it, though caudal to the transverse septum. It has been mentioned that this PPC establishes a connection between the pericardial cavity and the peritoneal cavity, so this connection is between the peritoneal cavity and ...

Highly Resolved Phylogenetic Relationships within Order Acipenseriformes According to Novel Nuclear Markers. [PDF]

Genes (Basel), 2019
Order Acipenseriformes contains 27 extant species distributed across the northern hemisphere, including so-called “living fossil” species of garfish and sturgeons. Previous studies have focused on their mitochondrial genetics and have rarely used nuclear genetic data, leaving questions as to their phylogenetic relationships. This study aimed to utilize
