Freshwater invertebrates of sub-Antarctic Marion Island
The freshwater habitats (mires, streams, lakes, pools and wallows) on sub-Antarctic Marion Island were examined for invertebrates. Sixty-eight species were found, including 45 new records for the Island. Of these 56 were bona fide aquatic invertebrates, the rest being terrestrial or brackish interlo...
