DOI: 10.1007/s00300-017-2144-x
Abstract: Unlike most phocid species (Phocidae), Mirounga leonina (southern elephant seals) experience a catastrophic moult where they not only replace their hair but also their epidermis when ashore for approximately 1 month. Few studies have investigated behavioural and… read more here.

DOI: 10.1016/j.anbehav.2017.03.006
Abstract: Long-term fidelity to foraging areas may have fitness benefits to individuals, particularly in unpredictable environments. However, such strategies may result in short-term energetic losses and delay responses to fast environmental changes. We used satellite tracking… read more here.

Abstract: The area west of the Kerguelen Islands (20–70°E/45–60°S) is characterized by a weak mesoscale activity except for a standing meander region of the Antarctic Circumpolar Current (ACC) localized between 20 and 40°E. A unique bio-physical… read more here.

DOI: 10.1093/conphys/coaa141
Abstract: Using thermographic images, we found that southern elephant seals use their flippers as body heat controllers, regulating their temperature in response to ambient conditions, especially air temperature. The appearance of thermal windows, specific areas on… read more here.

DOI: 10.1371/journal.pone.0172396
Abstract: Humans have devised fishing technologies that compete with marine predators for fish resources world-wide. One such fishery for the Patagonian toothfish (Dissostichus eleginoides) has developed interactions with a range of predators, some of which are… read more here.
