Local weather and body condition influence habitat use and movements on land of molting female southern elephant seals (Mirounga leonina)

recommendations! Published in 2018 at "Ecology and Evolution"

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.

DOI: 10.1038/s41467-024-53766-5

Abstract: H5N1 high pathogenicity avian influenza virus has killed thousands of marine mammals in South America since 2022. Here we report epidemiological data and full genome characterization of clade 2.3.4.4b H5N1 HPAI viruses associated with a… read more here.

DOI: 10.1038/s41598-025-87433-6

Abstract: Assessing the biological characteristics of high-latitude winter habitats of migratory marine predators is necessary for conservation and management in Antarctica. Tracking data from chinstrap penguins (Pygoscelis antarcticus) and southern elephant seals (Mirounga leonina), key Antarctic… read more here.

Breaking the fast: first report of dives and ingestion events in molting southern elephant seals

recommendations! Published in 2024 at "Communications Biology"

DOI: 10.1038/s42003-023-05720-2

Abstract: Southern elephant seals (SES) experience a ‘catastrophic molt’, a costly event characterized by the renewal of both hair and epidermis that requires high peripheral vascular circulation. Molting animals are therefore constrained by high metabolic heat… read more here.

DOI: 10.1038/s42003-025-08049-0

Abstract: The intricate relationship between trophic levels in marine ecosystems remains largely unexplored, particularly in the Southern Ocean. To investigate the complex composition of water constituents, notably the phytoplankton community, we used machine learning techniques to… read more here.

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

Sign Up to like & get
recommendations! Published in 2021 at "Conservation Physiology"

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: 10.1098/rsos.230666

Abstract: Understanding the ontogeny of diving behaviour in marine megafauna is crucial owing to its influence on foraging success, energy budgets, and mortality. We compared the ontogeny of diving behaviour in two closely related species—northern elephant… read more here.
