Benthic assemblages of Polychaeta in chosen regions of the Admiralty Bay (King George Island, South Shetland Islands)
Streszczenie
By means of the synthetic diagram method (Romaniszyn 1970) populations
of benthic Polychaeta at the depth ranging from 15 to 250 m of the Admiralty
Bay (South Shetland Islands) were analysed. During the summer season of 1979/80 three
replicate subsamples were taken at 18 stations situated along 3 crosssections using the
Van Veen grab of a catching area of 0.09 m²; 61 benthic taxa of Polychaeta were
recorded in these samples. The characteristics of particular assemblages are presented
together with their tendency to change as a result of substrate quality, depth and position
in the study area. Considerable affinity between the fauna of Polychaeta in the shallowest
part of the bay and the composition and structure of polychaete assemblages
occurring at Arthur Harbor (Anvers Island), which were described by Richardson and
Hedgpeth (1977) was recorded.
