Molecular phylogenetic relationships among five genera and twelve Mugilidae species were investigated using published mitochondrial cytochrome b and 16S rDNA sequences. These analyses suggested the paraphyly of the genus Liza and also that the separation of Liza, Chelon and Oedalechilus might be unnatural. Moreover, all the species of the genus Mugil plus orthologs of Crenimugil crenilabis clus...
Abstract Elopiformes is one of the most ancient orders Teleostei fishes and includes Megalopidae Elopidae families. Although relevant to scientific research, cytogenetic molecular data are lacking for both Here, we compared species from perspective genetic divergence cytogenetics elucidate chromosomal diversification evolutionary processes Elopiformes. The results showed that Megalops atlanticu...
The burbot, Lota lota (Teleostei: Gadidae), has a holarctic distribution, with one subspecies (Lota lota lota) living in the lakes and rivers of the Palaearctic and northwestern North America and the other (Lota lota maculosa) living in the Nearctic (except the northwest). We analysed nine microsatellite loci and the mitochondrial DNA control region of 350 burbot sampled across North America to...
Genetic species identification is often necessary for flocks, such as rockfishes in the genus Sebastes (Teleostei, Scorpaenidae). Traditional visual methods are challenged by presence of many sympatric rockfish with morphologically similar juveniles. Here we present a straightforward approach using 96 nuclear microhaplotype loci that can be efficiently genotyped high-throughput DNA sequencing. ...
Until recently, the Human Genome Project held centre stage in the press releases concerning sequencing programmes. However, in October 2001, it was announced that the Japanese puffer fish (Takifugu rubripes, Fugu) was the second vertebrate organism to be sequenced to draft quality. Briefly, the spotlight was on fish genomes. There are currently two other fish species undergoing intensive sequen...
The members of the cyprinid subfamily Gobioninae, commonly called gudgeons, form one of the most well-established assemblages in the family Cyprinidae. The subfamily is a species-rich group of fishes, these fishes display diverse life histories, appearances, and behavior. The phylogenetic relationships of Gobioninae are examined using sequence data from four loci: cytochrome b, cytochrome c oxi...
