DNA barcoding reveals both cryptic as true circumpolar species in Antarctic Lysianassoidea (Amphipoda)
Recent molecular analyses revealed that several so-called “circum-Antarctic” benthic crustacean species appeared to be complexes of cryptic species with restricted distributions. In this study we used a DNA barcoding approach based on mitochondrial cytochrome oxidase I gene sequences in order to det...
