Phylogeography of brook charr, Salvelinus fontinalis, in North America, based upon mitochondrial DNA variation
PCR amplified mitochondrial DNA of the control region and cytochrome b gene of brook charr ('Salvelinus fontinalis') sampled from 92 North American populations was sequenced to examine phylogenetic affinities among populations and assess the congruency of the data to previously reported RF...
