The first open-sea (non-coastal) Marine Protected Area (MPA) in Argentina was created in 2013 (and named “Namuncurá”), at Burdwood Bank, an undersea plateau located about 200 km south from Malvinas/Falkland Islands, SW Atlantic Ocean. This contribution represents the most recent and complete checklist of benthic organisms (mainly mega and macrofauna) that summarized 240 taxa collected at three sites in the mentioned area. The benthic richness here documented largely exceeds the values coming… 
Benthic communities in the Southwest Atlantic Ocean: Conservation value of animal forests at the Burdwood Bank slope
The characterization of benthic communities at the Burdwood Bank slope (≥200 m depth) is provided, comprising data from the marine protected area (MPA) Namuncura II (created in December 2018), as
Biodiversity of Isopoda and Cumacea (Peracarida, Crustacea) from the Marine Protected Area Namuncurá-Burdwood Bank, South-West Atlantic
TLDR
The biodiversity of the isopods and cumaceans from Burdwood Bank is typically Magellanic, and there is little correspondence between this fauna and that from the Antarctic Peninsula and Scotia Arc.
Asteroidea of the southern tip of South America, including Namuncurá Marine Protected Area at Burdwood Bank and Tierra del Fuego Province, Argentina
TLDR
TheN MPA showed higher asteroid richness than Tierra del Fuego Province and the surrounding shelf break, and a high percentage of the species found at the N MPA presented direct development with brooding females, indicating this area represents an important biodiversity hotspot.
Polychaetes from Burdwood Bank: “Namuncurá I” Marine Protected Area and slope, SW Atlantic Ocean
TLDR
Results indicate strong connections between the fauna collected at NMPA and the polychaetes assemblage in other Magellan areas dominated by soft bottoms.
Structure and distribution of fish assemblages at Burdwood Bank, the first Sub-Antarctic Marine Protected Area “Namuncurá” in Argentina (Southwestern Atlantic Ocean)
TLDR
The present data suggest that fishes are an important component of the benthic community planned to be protected by the implementation of the MPAN-BB, and have important implications for habitat preservation and threatened species conservation.
Stony corals (Anthozoa: Scleractinia) of Burdwood Bank and neighbouring areas, SW Atlantic Ocean
The presence of ten species of stony corals was recorded at a total of 19 out of 48 sampling stations at Burdwood Bank and neighbouring areas. Scleractinians were recorded only at three stations
The ecological role of brachiopods in the Namuncurá MPA/Burdwood Bank, off southern South America
TLDR
It is interpreted that brachiopods from the Namuncurá MPA/Burdwood Bank appear to play an important role in the biotic and trophic interactions of benthic Subantarctic marine fauna, whether acting as substrates, refuges, or food.
Important At-Sea Areas of Colonial Breeding Marine Predators on the Southern Patagonian Shelf
TLDR
This work used biotelemetry and biologging tags to track the movements of six seabird species and three pinniped species breeding at the Falkland Islands to provide comprehensive multi-species predictions for some of the largest marine predator populations on the Patagonian Shelf, which will contribute to future marine spatial planning initiatives.
Microbial plankton configuration in the epipelagic realm from the Beagle Channel to the Burdwood Bank, a Marine Protected Area in Sub-Antarctic waters
TLDR
The findings unfold the plankton configuration in the Southern Patagonian Shelf, ascribed as a sink for anthropogenic CO2, and highlight the diverse ecological traits that microorganisms develop to adjust their yield to changing conditions.

Species richness of marine Bryozoa in the continental shelf and slope off Argentina (south‐west Atlantic)
TLDR
The distribution pattern of benthic stations surveyed during the most important cruises in the area shows that the sampling effort has been biased towards southern shelf areas off Santa Cruz and Tierra del Fuego, as well as around the Malvinas (Falkland) islands.
Hydroid assemblages from the Southwestern Atlantic Ocean (34–42° S)
TLDR
A non-parametric multivariate similarity analysis revealed nine species groups that were correlated with large-scale and local oceanographic patterns and with the availability of suitable substrata, and the main hydroid substrata for eight of the groups were cnidarians, molluscs, quartzite rocks and sponges.
Changes in a benthic megafaunal community due to disturbance from bottom fishing and the establishment of a fishery closure
TLDR
It is indicated that bottom fishing needs to be reduced to infrequent intervals to sustain the benthic species composition of Georges Bank at a high level of biodiversity and abundance.
Biodiversity of Porifera in the Southwest Atlantic between 35º S and 56º S
TLDR
Biodiversity of Porifera is weakly but significantly correlated with latitude, since stations between 50o S and 55o S were on average richer than those located off Buenos Aires Province and around the Malvinas/Falkland Islands.
Benthic richness in the Argentine continental shelf: the role of Zygochlamys patagonica (Mollusca: Bivalvia: Pectinidae) as settlement substrate

TLDR
Zygochlamys patagonica shells constitute conspicuous hard substrate available for the settlement of sessile organisms, which leads to an increased benthic richness in the continental soft-bottom areas of the Argentine Sea, where scallop beds are located.
Ascidians (Tunicata, Ascidiacea): species distribution along the Scotia Arc
TLDR
Affinity between the ascidian fauna of the Magellan region and the Antarctic is slightly stronger than was previously considered; there is also a species gradient along the Scotia Arc, which can be regarded as a bridge between the two regions.
