Bouvet (Bouvetøya) is a geologically young and very remote island just south of the Polar Front. Here we report samples taken during the RV “Polarstern" cruise ANTXXI/2 on 3 days in November 2003 and January 2004. This work was part of SCAR’s EASIZ programme and intended, by providing data on the marine fauna of this “white gap" in the Atlantic sector of(More)
To elucidate spatial assemblage patterns during 2 consecutive austral summer seasons, we sampled intensively the macrofauna from 73 stations located at the southern coast of Livingston Island. Representatives of 28 higher taxonomic groups were used for the faunal analysis. While two faunal descriptors (i.e. group richness and total biomass) changed markedly(More)
The current work presents new data on the pycnogonids collected during the ANTXXI/2 cruise on board of “Polarstern” R/V during December 2003 and January 2004 in the Eastern Weddell Sea (Antarctica). Twenty-eight samples were taken, with different trawls, from depths between 120 and 1,866 m. In total, 251 specimens of pycnogonids, belonging to 31 species,(More)
During the austral summer 1995, suprabenthic samplings were carried out at 24 stations (depth range 45–649 m) located around Livingston Island, within the caldera of Deception Island and in the Bransfield Strait. At each station, the near-bottom motile fauna was simultaneously collected with a multinet Macer-GIROQ sled in three water layers above the(More)
The Bellingshausen and Amundsen Seas are among the least studied Antarctic areas. Pycnogonids constitute a common and conspicuous component of the Antarctic marine fauna. Antarctic pycnogonids have been widely studied and are usually more abundant than elsewhere. Therefore, they represent a key taxon to understand the zoogeographic and bathymetric(More)
Biodiversity and biogeographic studies comparing the distribution patterns of benthic marine organisms across the Iberian Atlantic and Mediterranean waters are scarce. The Pycnogonida (sea spiders) are a clear example of both endemicity and diversity, and are considered a key taxon to study and monitor biogeographic and biodiversity patterns. This is the(More)
The name of the new species Nymphon nakamurai described in the paper entitled ''Pycnogonida from the Bellingshausen and Amundsen Seas: taxonomy and bio-diversity'' () was already held by a pycnogonid species described by Stock (1994). Therefore, Nymphon nakamurai is an invalid name for this new species, and the correct name is Nymphon koichiroi.
A new pycnogonid species of the genus Pycnogonum is described from Flemish Cap (Northwest Atlantic Ocean) at 1453-1462 m depth. Pycnogonum bamberi sp. nov. is compared with its congeners, from which it can be distinguished by the combination of a glans-shaped proboscis, the low, transverse ridges that lie on the dorsodistal surfaces of the first coxae and(More)
