Rôle de la glace saisonnière dans la dynamique de l'écosystème marin de l'Antarctique : impact potentiel du changement climatique global

VertigO, 2004
Seasonal ice cover is linked to an intense biological activity in polar regions. Every year, ice melting induces the stabilisation of the water column which can be observed until 150 km from the margin of seasonal ice, favoring the development of profuse

Antarctic Ocean Legacy: Towards Protection of the Weddell Sea Region [PDF]

, 2014
Ice-bound, wild and remote, the Weddell Sea is a large, deep embayment nestled between the Antarctic Peninsula and Cape Norvegia. Lying south of the Atlantic Ocean, it is one of the most intact ecosystems in the world.At its widest, it is 2,000 km across,

Dietary antarctic krill improves antioxidant capacity, immunity and reduces lipid accumulation, insights from physiological and transcriptomic analysis of Plectropomus leopardus

BMC Genomics
Background Due to its enormous biomass, Antarctic krill (Euphausia superba) plays a crucial role in the Antarctic Ocean ecosystem. In recent years, Antarctic krill has found extensive application in aquaculture, emerging as a sustainable source of ...

How does Drake Passage Oscillation Index (DPOI) effect on variability of the Antarctic krill ecosystem in the Antarctic Peninsula region? [PDF]

, 2016
Antarctic krill, Euphausia superba Dana, is a keystone species of the Antarctic ecosystem. Environmental and ecological change in Antarctica is one of key issues for the global climate change.

Rich microbial and depolymerising diversity in Antarctic krill gut

Microbiology Spectrum
With almost a quadrillion individuals, the Antarctic krill processes five million tons of organic carbon every day during austral summer. This high carbon flux requires a broad range of hydrolytic enzymes to decompose the diverse food-derived biopolymers.

Penguin guano suppresses the grazing rate and modifies swimming behavior in Antarctic Krill (Euphausia superba)

Frontiers in Marine Science
Antarctic krill (Euphausia superba) are a key component of the Antarctic ecosystem linking primary and some secondary production to higher trophic levels including fish, penguins, seals, and whales.

Polar Oceans in Peril and a Planet at Risk [PDF]

, 2009
The snow-covered lands and icy waters of these polar regions are, for many people, the purest examples of true wilderness left on this planet. While the Arctic has been home to indigenous peoples for millennia, Antarctica has only played host to visiting
