Insular marine biotas are often richer in faunal diversity than those from the open sea in the same geographical region. The existence of particular island effects were tested under polar conditions by comparing infaunal benthic assemblages on Peter I Island with those of similar latitudes in the open ocean at the Bellingshausen Sea and also from the coast of the Antarctic Peninsula. Sampling was carried out aboard the R/V Hespérides during the expedition named BENTART-2003 from 24 January to 3… 
Intertidal benthic communities associated with the macroalgae Iridaea cordata and Adenocystis utricularis in King George Island, Antarctica
This study provides a first baseline on the diversity and abundance of benthic assemblages associated with intertidal macroalgae in the southwest of King George Island.
Redescription of Tubulanus mawsoni (Wheeler 1940) comb. nov. (Palaeonemertea: Tubulanidae) from the Bellingshausen Sea (Antarctica)
The need for new morphological and molecular studies is suggested based on the ambiguities between Tubulanus diagnosis and the species descriptions, as well as the possible paraphyletic status of the genus.
Estudio de los equinodermos antárticos del mar de Bellingshausen
El Mar de Bellingshausen (MB) es el tercer mar en importancia en el Oceano Antartico pero debido a las condiciones extremas de hielo es una de las zonas de la Antartida menos estudiada. Las campanas


Community structure and spatial distribution of benthic fauna in the Bellingshausen Sea (West Antarctica)
Positive correlations were found between the faunal distribution and a combination of depth, redox values, and organic matter content of sediments, which indicates decreasing availability of food in the deeper bottoms of the Bellingshausen Sea with a prevalence of depauperated bottoms dominated almost exclusively by a foraminiferans community.
Patterns in the benthic communities on the shelf of the sub-Antarctic Prince Edward Islands
Benthic communities at the sub-Antarctic Prince Edward Islands were sampled qualitatively with an epi-benthic sled at 57 stations over a five year period and there seems to have been a diverse colonisation.
Diversity and distribution of mollusc assemblages on the Victoria Land coast and the Balleny Islands, Ross Sea, Antarctica
In 2004 as part of the joint Latitudinal Gradient Project in the Ross Sea, cruises of RV Tangaroa and RV Italica along the Victoria Land coast and the Balleny Islands collected 142 species of mollusc
Epibenthic macrofauna associated with the shelf and slope of a young and isolated Southern Ocean island
Abstract The remote South Sandwich arc is an archipelago of small volcanic islands and seamounts entirely surrounded by deep water and about 600 km away from the closest island, South Georgia. As
Polychaete diversity at tropical Atlantic deep-sea sites: environmental effects
Diversity patterns observed in the EUMELI sites seem best explained by the intermediate productivity theory, and the rate of production encountered at the eutrophic site may overcome much of the impact of physical and biological disturbances, favouring a diverse species assemblage.
Mega-epibenthos at Bouvet Island (South Atlantic): a spatially isolated biodiversity hot spot on a tiny geological spot
The observed uncoupling of intermediate-scale from large-scale background species diversity on the Antarctic shelf raises the question whether in these benthic systems an upper capacity limit for diversity exists.
Missing link in the Southern Ocean: sampling the marine benthic fauna of remote Bouvet Island
Samples taken during the RV “Polarstern" cruise ANTXXI/2 on 3 days in November 2003 and January 2004 are reported to contribute to identifying the role of Bouvet in the faunal exchange between the Sub- and high Antarctic.
Antarctic marine benthic diversity
Comparisons with tropical and temperate regions suggest that decapods, bivalves and teleost fishes are poorly represented in the Southern Ocean benthic marine fauna, whereas pycnogonids, echinoderms and many suspension feeding groups are rich and diverse.
Abundance and distribution of invertebrate larvae in the Bellingshausen Sea (West Antarctica)
The abundance and diversity of larval types found in the Bellingshausen Sea during the BENTART-06 cruise support the hypothesis that indirect development through larval swimming stages plays a key role in benthic recruitment in polar areas.

Abstract Shelf and slope cryptofauna were sampled at the most northerly shelf environments within the Southern Ocean, Shag Rocks. The area is remarkably rich, with seven phyla, 10 classes, 40
