Marked phylogeographic structure of Gentoo penguin reveals an ongoing diversification process along the Southern Ocean
© 2016 Elsevier Inc. Two main hypotheses have been debated about the biogeography of the Southern Ocean: (1) the Antarctic Polar Front (APF), acting as a barrier between Antarctic and sub-Antarctic provinces, and (2) the Antarctic Circumpolar Current (ACC), promoting gene flow among sub-Antarctic ar...
