The Antarctic Cyclopoid Oncaea Antarctica - some aspects of its biology and ecology
Languages of publication
The biology and ecology of an Antarctic species Oncaea antarctica, which belongs to the Cyclopoida, was reconstructed from analyses of vertically-stratified zooplankton sets of samples taken with a 150 *m and 250 *m-mesh net during the day and at night, during 3 austral seasons (sum-mer - December 1985, autumn - April 1988, winter - June-August 1989). The plankton material was collected at stations located in Croker Passage (Antarctic Peninsula). Inhabiting meso- and bathypelagic waters, O. antarctica was one of the most numerous cyclopoids of the family Oncaeidae, making up 50% of all Cyclopoida in winter. Females carrying egg sacs and copulating pairs of this species were present during all three seasons investigated.
