Fast climate changes in the Antarctic Peninsula are reducing krill density, which, by its turn, is reflected in penguin population dynamics. The increased concentration of fishing activities in this area in the last two to three decades is believed to have feedbacked the impacts of climate change over penguin populations.

Its implementation will establish a new scenario for the current krill fishing fleet dynamic, therefore it is necessary to understand what represent each D1MPA zones for the fishery. We analysed the trend of different fishing indicators among the D1MPA zones during the period Read More

Important marine mammal areas (IMMAs) – scientific protocol S. Gallon, P. Marras-Aït Razouk and Y. Ropert-Coudert
Résumé:
The Marine Mammal Protected Areas Task Force (MMPA Task Force) was established in 2013 by the International Committee on Marine Mammal Protected Areas (ICoMMPA), the International Union for Conservation of Nature (IUCN), the Vice-Chair of the World Commission on Protected Areas (WCPA), and the Members of the IUCN Species Survival Commission (SSC).
This group organises scientific Read More

Krill faecal pellets drive hidden pulses of particulate organic carbon in the marginal ice zone A. Belcher, S.A. Henson, C. Manno, S.L. Hill, A. Atkinson, S.E. Thorpe, P. Fretwell, L. Ireland and G.A. Tarling
Résumé:
The biological carbon pump drives a flux of particulate organic carbon (POC) through the ocean and affects atmospheric levels of carbon dioxide. Short term, episodic flux events are hard to capture with current observational techniques and may thus be underrepresented in POC flux estimates. We model the potential hidden flux of POC originating from Antarctic krill, whose swarming behaviour Read More

Krill (Euphausia superba) distribution contracts southward during rapid regional warming A. Atkinson, S.L. Hill, E.A. Pakhomov, V. Siegel, C.S. Reiss, V.J. Loeb, D.K. Steinberg, K. Schmidt, G.A. Tarling, L. Gerrish and S.F. Sailley
Résumé:
High-latitude ecosystems are among the fastest warming on the planet. Polar species may be sensitive to warming and ice loss, but data are scarce and evidence is conflicting. Here, we show that, within their main population centre in the southwest Atlantic sector, the distribution of Euphausia superba (hereafter, ‘krill’) has contracted southward over the past 90 years. Near their Read More

Stable isotope analysis reveals trophic variation in adult Antarctic krill (Euphausia superba) around the Antarctic Peninsula from austral fall to early winter H.T. Zhang, G.P. Zhu, Q. Song, S.Q. Wang, Y. Yang and Q.Y. Yang
Résumé:
The Antarctic krill (Euphausia superba) is a key species in the Southern Ocean ecosystem and an important link in the food web of the Antarctic ecosystem. The trophic information for this species during the transition from the austral fall to the winter is important to understand its poorly known overwintering mechanisms. However, the few studies on the topic differ in their results, Read More

How trophic dynamics of adult Antarctic krill Euphausia superba responses to the condition of no ice in the water during the winter: a case study at South Georgia? G.P. Zhu, H.T. Zhang, B. Deng and Q.Y. Yang
Résumé:
Understanding the variation in krill diet during winter is crucial to elucidate the overwintering of krill in the Southern Ocean. The information on trophic variation of krill under ice-free waters during the winter can also provide the insight for understanding the response of krill to global warming. Stable isotope analyses (15N/14N and 13C/12C) Read More
