Phylogeography of a high-dispersal New Zealand sea-star: does upwelling block gene-flow?

abstract：:As natural selection must act on underlying genetic variation, discovering the number and location of loci under the influence of selection is imperative towards understanding adaptive divergence in evolving populations. Studies employing genome scans have hypothesized that the action of divergent selection should red...
