The validation of specific status of the sakhalin sturgeon Acipenser mikadoi (Acipenseridae) in the light of recent genetic and morphological data

The taxonomic relations between the Sakhalin and North American green sturgeons were re-evaluated based on afresh conducted comparative morphological analysis of both sturgeons, as well as a renovation of literature cytogenetic, molecular and morphological data. The comparative analysis of different...

Description
Summary:The taxonomic relations between the Sakhalin and North American green sturgeons were re-evaluated based on afresh conducted comparative morphological analysis of both sturgeons, as well as a renovation of literature cytogenetic, molecular and morphological data. The comparative analysis of different data sets demonstrates the validity of the Sakhalin sturgeon A. mikadoi which differs from the North American green sturgeon A. medirostris in the karyotype structure, the nuclear DNA content value, and several morphological characters. The key for their identification is presented.
