Phylogeographical structure of the Dover sole Microstomus pacificus: the larval retention hypothesis and genetic divergence along the deep continental slope of the northeastern Pacific Ocean
Abstract Population genetic variability and phylogeographical structure of the Dover sole, Microstomus pacificus (Teleostei: Pleuronectidae), were examined along the continental slope of the northeastern Pacific Ocean using sequences of the left domain of the mitochondrial DNA (mtDNA) control region...
