title: Phylogeography of Semiterrestrial Isopod, Tylos granuliferus, on East Asian Coasts.
abstract: We conducted phylogenetic analyses using mitochondrial COI gene sequences of Tylos granuliferus, a semiterrestrial coastal isopod in East Asia, to clarify possible phylogeographic patterns and to assess relationships between present and past marine environments and genetic population structures. Our results strongly suggest the presence of four clades of T. granuliferus, one of which consists of three subclades. The distribution pattern of clades and subclades seems to have been affected by ocean current activities. Our results also suggest that historical changes in oceanic environments and the subsequence bifurcation of current streamlines affected the first and second divergences of T. granuliferus during the late Miocene and near the beginning of the Pliocene, respectively.
