Species composition, seasonal abundance and population structure of chaetognaths in Admiralty Bay (Antarctic)
Abstract Although chaetognaths inhabiting polar ecosystems are relatively well known, there are few reports on their functioning in the Antarctic coastal plankton community. The presented results provide the first comprehensive description of population structure of chaetognaths in the neritic zone...
