A new pelagic Alteutha (Copepoda: Harpacticoida) from Potter Cove, King George Island, Antarctica - Description, ecology and information on its year round distribution
A new harpacticoid copepod species was found during a year round plankton survey in a shallow Antarctic bay. Both the dominant Calanoida and Cyclopoida and the often neglected Harpacticoida, their abundances in relation to sea-ice formation and decline in presence of Euphausia superba are regarded,...
