“…The presence of microphagous detritus feeders: burrowers and surface deposit feeders is typical for the soft bottom (Gallardo et al 1988;Gambi and Busotti 1999;San Martin et al 2000;Sicinski 2004). A dominance of macrophagous motile polychaetes, herbivores or predators had already been observed on macroalgal holdfasts and thalli in the Antarctic as well as in other regions of the world (Arnaud 1974;Rios et al 2007;Fraschetti et al 2002).…”

The polychaete community associated with holdfasts of the brown alga Himantothallus grandifolius in Admiralty Bay has been studied. It is the first study of its kind in this area and only the second in the Antarctic. Samples were collected in the summer season of 1979/ 1980 from a depth range of 10-75 m. Seventy-eight species were found on 19 holdfasts. The community was dominated by Brania rhopalophora and Neanthes kerguelensis. Analysis of similarity showed that polychaete fauna associated with this habitat did not show any partitioning related to depth. Regression analysis showed that densities of both species and individuals decreased with increased holdfast volume. A positive correlation was found between the number of individuals and holdfast volume. Polychaetes from 10 feeding guilds were found with dominance of macrophagous motile herbivores and sessile filter feeders. The complex habitat provided by holdfasts is a shelter for a rich polychaete fauna and may function as important protection from disturbance in the shallow areas of Admiralty Bay.

“…Furthermore, Bullivant (1967b) described the ''Deep Shelf Mud Bottom Assemblage'' dominated by polychaetes, which was found close to Coulman Island. In their quantitative analysis of the Ross Sea benthos in 1994 and 1995, Gambi and Bussotti (1999) excluded the very few colonial organisms (sponges, cnidarians, and bryozoans), which were found in the samples. From there a comparison of the two studies should be simplified, still the different gear used has to be taken into account.…”

Distribution and composition of macrozoobenthic communities along a Victoria-Land Transect (Ross Sea, Antarctica)

et al. 2006

The Victoria-Land Transect project onboard the Italian research vessel ''Italica'' in February 2004, was a large-scale attempt to obtain benthic samples of smaller macrozoobenthic specimens systematically along a latitudinal and a depth transect along the VictoriaLand coast. Data presented from this survey are based on Rauschert dredge samples, which were taken at four areas at depth ranging from 84 to 515 m. A cluster analysis based on relative numbers of abundance was performed and demonstrated a change in community structure depending on the location along the latitudinal transect. A change in community structure with depth was not recorded. Dominant taxa of the Ross Sea fauna along the Victoria-Land coast were the Arthropoda (65.7%), followed by Annelida (20.7%), Mollusca (9.6%) and Echinodermata (2.5%). Total number of abundance decreased with depth with an exception at Cape Russell, whereas a trend in biomass was not documented. Abundance and biomass proportions of major taxa changed gradually along the latitudinal transect.

“…Even though Amphipoda play a very important role in the Southern Ocean benthic communities, in the majority of ecological studies they are identified only to the order level (e.g. Sáiz-Salinas et al 1997;Gambi and Bussotti 1999;Barnes et al 2006;Rehm et al 2006Rehm et al , 2011Glover et al 2008;Saiz et al 2008;Cummings et al 2010). Taxonomical studies are time consuming and difficult, which led several authors to search for Abstract Amphipoda belong to enormously diverse benthic invertebrate groups in the Southern Ocean, playing a very important role in the Antarctic communities.…”
