Toward a Phylogenetic Taxonomy of Sturgeons (Acipenseriformes: Acipenseridae)

open access: yesBulletin of the Peabody Museum of Natural History
Acipenseriformes, comprising sturgeons and paddlefishes, is one of the three ancient and species-poor living lineages of non-teleost Actinopterygii. Here, we use DNA sequence and morphological data to investigate the phylogenetic relationships of sturgeons and produce a phylogenetic basis for the taxonomy of Acipenseridae.
