Multi-Marker Mitochondrial Analysis Reveals Genetic Diversity and Phylogenetic Relationships of Black Sea Sturgeons (Acipenseridae). [PDF]
Ecol EvolSturgeons are an important species due to their complex genetic structure and evolutionary characteristics. Unfortunately, they are threatened with extinction due to illegal and overfishing, as well as the loss of their natural habitats. In our work, we examine the genetic diversity of four sturgeon species that inhabit the Black Sea basin and its ...

Fertility of a spontaneous hexaploid male Siberian sturgeon, Acipenser baerii [PDF]
BMC Genetics, 2014 Evolution of sturgeons and paddlefishes (order Acipenseriformes) is inherently connected with polyploidization events which resulted in differentiation of ploidy levels and chromosome numbers of present acipenseriform species. Moreover, allopolyploidization as well as autopolyploidization seems to be an ongoing process in these fishes and individuals ...
