Life-cycle strategies of Calanoides acutus, Calanus propinquus, and Metridia gerlachei (Copepoda: Calanoida) in the eastern Weddell Sea, Antarctica
The dominant Antarctic copepods Colanoides acutus, Calanus propinquus , and Metridia gerlachei were studied in the eastern Weddell Sea during mid-winter (July/August 1986), late winter/early spring (October/November 1986), summer (January/February 1985), and autumn (April/May 1992).
