Evolutionary processes that shaped the diversity of the amphipod genus Eusirus in the Southern Ocean
editorial reviewed Various evolutionary processes greatly influenced by the geological and climatic history shaped the diversity of the current Antarctic marine fauna. In the past, these Antarctic species have survived different glacial cycles through dispersal to refugia, and/or adaptations to nove...
