Geographic range and structure of cryptic genetic diversity among Pacific North American populations of the non-native amphipod Grandidierella japonica. Biol. Invasions 15:2415-2428. Comments: It is native to the Pacific Ocean and has probably spread to the Baltic Sea with the aid of ballast water and biofouling (Berggren 2015, Jourde et al 2013). The species lack a pelagic larva stage and hence it spreads either by adult movement or attached to drifting objects. In North America the spreading is associated to ship traffic (Pilgrim et al 2013). |
