DOI: 10.1002/ece3.4049
Abstract: Abstract Southern elephant seals (Mirounga leonina) are known to move and aggregate while molting, but little is known about their behavior on land during this time. In this study, 60 adult females were monitored (23… read more here.

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.

Slow to change? Individual fidelity to three-dimensional foraging habitats in southern elephant seals, Mirounga leonina

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.

DOI: 10.1016/j.anbehav.2017.05.007
Abstract: The marginal value theorem models patch departure decisions for foraging animals when resources are unevenly distributed. A key component of these models is the decelerating energy gain function used to represent patch depletion. However, the… read more here.

DOI: 10.1016/j.anbehav.2020.06.014
Abstract: Dominance hierarchies structure the adult social networks of many mammals. To identify the conditions that support the establishment of stable hierarchical relationships within groups of familiar rivals, we explored the ontogeny of spatial, social and… read more here.

Conditions influencing the appearance of thermal windows and the distribution of surface temperature in hauled-out southern elephant seals

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: 10.1152/physiol.2023.38.s1.5794987
Abstract: Marine mammals face increased human activities in the ocean, including shipping, recreation, and seismic exploration. Such disturbances may alter short-term behavior and long-term life history patterns; however, many of the mechanistic details of responses remain… read more here.

Adiposity and fat metabolism during combined fasting and lactation in elephant seals
Sign Up to like & getrecommendations! Published in 2018 at "Journal of Experimental Biology"
DOI: 10.1242/jeb.161554
Abstract: ABSTRACT Animals that fast depend on mobilizing lipid stores to power metabolism. Northern elephant seals (Mirounga angustirostris) incorporate extended fasting into several life-history stages: development, molting, breeding and lactation. The physiological processes enabling fasting and… 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.
