  • Title: A molecular phylogeny of the Percidae (Teleostei, Perciformes) based on mitochondrial DNA sequence.
    Author: Sloss BL, Billington N, Burr BM.
    Journal: Mol Phylogenet Evol; 2004 Aug; 32(2):545-62. PubMed ID: 15223037.
    Abstract:
    The family Percidae is among the most speciose families of northern hemisphere fishes with > 178 178 North American species and 14 Eurasian species. Previous phylogenetic studies have been hampered by a lack of informative characters, inadequate taxonomic sampling, and conflicting data. We estimated phylogenetic relationships among 54 percid species (9 of 10 genera and all but one subgenus of darters) and four outgroup taxa using mitochondrial DNA data from the 12S rRNA and cytochrome b genes. Four primary evolutionary lineages were consistently recovered: Etheostomatinae (Ammocrypta, Crystallaria, Etheostoma, and Percina), Perca, Luciopercinae (Romanichthys, Sander, and Zingel), and Gymnocephalus. Except Etheostoma and Zingel, all polytypic genera were monophyletic. The Etheostoma subgenus Nothonotus failed to resolve with other members of the genus resulting in a paraphyletic Etheostoma. The subfamily Percinae (Gymnocephalus and Perca) was not recovered in phylogenetic analyses with Gymnocephalus sister to Luciopercinae. Etheostomatinae and Romanichthyini were never resolved as sister groups supporting convergent evolution as the cause of small, benthic, stream-inhabiting percids in North American and Eurasian waters.
