Molecular phylogeny of a red-snow-crab species complex using mitochondrial and nuclear DNA markers.
Nucleotide sequence variation of mitochondrial DNA COI and nuclear rRNA gene regions was used to reconstruct phylogenetic relationships for the red-snow-crab species complex, including the red snow crab, Chionoecetes japonicus, its nominal subspecies, C. japonicus pacificus, and the triangle tanner...

Nucleotide sequence variation of mitochondrial DNA COI and nuclear rRNA gene regions was used to reconstruct phylogenetic relationships for the red-snow-crab species complex, including the red snow crab, Chionoecetes japonicus, its nominal subspecies, C. japonicus pacificus, and the triangle tanner crab, C. angulatus. The topologies of the Bayesian and neighbor-joining (NJ) trees of the COI and of NJ trees of rRNA sequences placed C. japonicus and C. angulatus in a single clade. The net sequence divergence between these taxa was d(net) = 0.000 in COI, and strongly suggests that these taxa represent a single species. In contrast, haplotypes in C. j. pacificus clustered separately from the C. japonicus - C. angulatus clade.
