Marine ecosystems' responses to climatic and anthropogenic forcings in the Mediterranean
The semi-enclosed nature of the Mediterranean Sea, together with its smaller inertia due to the relative short residence time of its water masses, make it highly reactive to external forcings, inExpand
Cryptic speciation and the circumpolarity debate: A case study on endemic Southern Ocean octopuses using the COI barcode of life
Three hundred and fifty specimens of the endemic Southern Ocean octopus genus Pareledone, were sequenced for the barcoding gene COI. Geographic coverage comprised the South Shetland Islands, the RossExpand
Is the Species Flock Concept Operational? The Antarctic Shelf Case
TLDR
The present study contradicts the paradigm that marine species flocks are rare and proposes a new protocol which includes an iterative fine-tuning of the monophyly and endemicity criteria in order to discover unsuspected flocks. Expand
Persistent organic pollutants in benthic and pelagic organisms off Adélie Land, Antarctica.
TLDR
Although POP levels in Antarctic marine organisms were substantially lower than in Arctic and temperate organisms, very little is known about their toxic effects on these cold-adapted species, with high degree of endemism. Expand
Comprehensive sampling reveals circumpolarity and sympatry in seven mitochondrial lineages of the Southern Ocean crinoid species Promachocrinus kerguelensis (Echinodermata)
TLDR
The phylogeny of Promachocrinus phylogroups reveals two principal clades that may represent two different cryptic species with contrasting demographic histories, suggesting multiple glacial refugia in the Southern Ocean. Expand
Crinoid phylogeny: a preliminary analysis (Echinodermata: Crinoidea)
TLDR
The overall direction of evolution in the gene trees remains uncertain: an asteroid outgroup places the root on the branch adjacent to the slowly evolving isocrinids (consistent with palaeontological order of first appearances), but maximum likelihood analysis with a molecular clock places it elsewhere.

Antarctic Ascidians (Tunicata) of the French-Australian survey CEAMARC in Terre Adélie
TLDR
A large collection of ascidians was made during the CEAMARC Aurora Australis V3 cruise off Terre Adelie and George V Land a region rarely investigated before at these depths, and three of the 33 ascidian species identified are new and belong to the Stolidobranchia. Expand
Developing priority variables (“ecosystem Essential Ocean Variables” — eEOVs) for observing dynamics and change in Southern Ocean ecosystems
Reliable statements about variability and change in marine ecosystems and their underlying causes are needed to report on their status and to guide management. Here we use the Framework on OceanExpand
Community structure and benthic habitats across the George V Shelf, East Antarctica: trends through space and time
Physical and biological characteristics of benthic communities are analysed from underwater video footage collected across the George V Shelf during the 2007/2008 CEAMARC voyage. Benthic habitats areExpand
Macroepibenthic communities at the tip of the Antarctic Peninsula, an ecological survey at different spatial scales
TLDR
An ecological macroepibenthic survey was conducted in three ecoregions in the north-western Weddell Sea to improve the so far poor knowledge of the structure of this component of the Southern Ocean ecosystem and its ecological driving forces and can provide a baseline to assess the impact of ongoing climate change to the benthic diversity, functioning and ecosystem services.
