Pleistocene climate cycles greatly influenced the distributions of kelps in northern seas and gated trans-Arctic dispersals between the North (N) Pacific and N Atlantic oceans. Here, we used partial sequences of the mitochondrial DNA cytochrome oxidase I-5′ (COI) and plastid ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit-3′ (rbcL) to resolve the phylogeography of the kelp Hedophyllum nigripes in the Gulf of Alaska and globally. In the Gulf of Alaska, genetic diversity was moderate (COI: h = 0.493 ± 0.076, n = 57; rbcL: h = 0.578 ± 0.00047, n = 54), but nucleotide diversity was small (COI: θπ = 0.00114 ± 0.00100, n = 57; rbcL: θπ = 0.0001 ± 0.00089, n = 54). Concatenated sequen..
