Abstract:
In the course of the ANDEEP-SYSTCO project, during the ANT XXIV-2 expedition in austral summer 2007/2008, the diversity and composition of the Polychaeta of the Antarctic deep-sea and adjacent South Atlantic basins were analyzed. A total of 847 individuals of 31 families were found belonging to 86 different species. Calculation of diversity (Shannon-Wiener Index, Pielou's Evenness) and the general species composition of Polychaeta showed patterns typical for the deep sea, with high species richness and low abundances. Lowest diversity was found in the Agulhas Basin in over 4000 m water depth. Lowest Evenness was found on top of Maud Rise where one-third of all Polychaeta belonged to one species. Cluster analyses resulted in higher affinities of Maud Rise to the Agulhas Basin than to the Antarctic continental slope. Explanations are sought in similarities of environmental factors (e.g., sediment, food input).
