1. Stable isotope analysis reveals trophic variation in adult Antarctic krill (Euphausia superba) around the Antarctic Peninsula from austral fall to early winter

   Abstract:  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

2. 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?

   Abstract:  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

3. VME detection thresholds: preliminary results of a study on the case of the sea pens (Pennatulacea) of the CCAMLR sector 58.4.4b

   Abstract:  CCAMLR has defined Vulnerable Marine Ecosystems (VME) detection thresholds based on the benthos bycatch monitoring. When these thresholds are reached during a single longline fishing operation, the data are reported to the Secretariat to inform the CCAMLR about the potential presence of

4. Adult male Antarctic fur seals: tourists, trouble makers or marine ecosystem sentinels?

   Abstract:  Resource competition often results in mechanisms that ameliorate its effects, typically through the partitioning of resource exploitation either temporally or spatially.  Understanding the spatial and temporal overlap between predators that exploit the same resource then is fundamental

5. Population variability of biological parameters of penguins along the Antarctic Peninsula

   Abstract:  A collection of published papers about population variability of several biological parameters and factors affecting penguins biology along the Antarctic Peninsula is presented in order to contribute to the general knowledge of penguin biological variation, to generate a data baseline in

6. Krill physiology and impact of temperature variations: a comparative approach

   Abstract:  The purpose of this "paper" is to present a research project in progress on the physiology of Antarctic krill, with a focus on the response to environmental temperature variations. This study first focused on the study of heat shock proteins (HSP) and the comparative aspect

7. Unfolding connectivity patterns along the Antarctic Circumpolar Current in the sub-Antarctic region

   Abstract:  The sub-Antarctic region-here considered between the sub-Antarctic Front and the southern boundary of the Antarctic Circumpolar Current (ACC)-falls under many distinct jurisdictions, including Exclusive Economic Zones (EEZs) of several countries, as well as the areas of competence of

8. Extinction risk of Antarctic and sub-Antarctic colonies of Pygoscelid penguins under climate change context

   Abstract:  Several studies have emphasized the variable abundance of Pygoscelid penguins from different colonies around Antarctica. In this study, the extinction risk of Adélie, Chinstrap and Gentoo penguins was evaluated in order to identify the most endangered colonies under present-day and

9. Important marine mammal areas (IMMAs) – scientific protocol

   Abstract:  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),

10. Supervised and unsupervised (RapidKrill) estimates of krill density from DY098

    Abstract:  We compare supervised, using the interactive software Echoview™, and unsupervised, using python,  processing  of acoustic  data  collected  during  the  UK  cruise  DY098.  The  same  data processing procedures are applied in both methods, and we show that the unsupervised method comes
