Elephant seal dive behaviour responds consistently to changes in foraging success regardless of sex or ocean habitat PeerJ, 2025 (Ref: 17475)
Category 1: Peer-reviewed literature

Understanding how air-breathing diving animals moderate their dive behaviour when foraging successfully is foundational in the study of their foraging ecology. Yet, this fundamental relationship remains unresolved with previous research pointing to inconsistent relationships…

Elephant seals as sentinels of the ongoing changes affecting the Southern Ocean: Disentangling environmental and maternal effects on pup size and body condition Science of the Total Environment, 2025 (Ref: 17372)
Category 1: Peer-reviewed literature

The weaning mass of southern elephant seal pups (Mirounga leonina) is a key predictor of their first-year survival probability. However, variations in pup morphometric characteristics (length, mass and body condition i.e. the residual of the allometric relationship between log(mass) and log(length))…

Oceanic Regime Shift to a Warmer Continental Shelf Adjacent to the Shackleton Ice Shelf, East Antarctica Journal of Geophysical Research: Oceans, 2023 (Ref: 17460)
Category 1: Peer-reviewed literature

The long-held view that the East Antarctic margin is isolated from warm offshore waters has been challenged by recent observations showing incursions of warm modified Circumpolar Deep Water (mCDW) reaching several East Antarctic ice shelves. However…

Southern Ocean pinnipeds provide bathymetric insights on the East Antarctic continental shelf. Communications Earth and Environment, 2023 (Ref: 17075)
Category 1: Peer-reviewed literature

Poor coverage of the Antarctic continental shelf bathymetry impedes understanding the oceanographic processes affecting Antarctica’s role in global climate. Continental shelf bathymetry influences warm modified Circumpolar Deep Water movement onto the shelf…

Variability in sea ice cover and climate elicit sex specific responses in an Antarctic predator Scientific Reports, 2017 (Ref: 17049)
Category 1: Peer-reviewed literature

Contrasting regional changes in Southern Ocean sea ice have occurred over the last 30 years with distinct regional effects on ecosystem structure and function.

Under the sea ice: Exploring the relationship between sea ice and the foraging behaviour of southern elephant seals in East Antarctica Progress in Oceanography, 2017 (Ref: 17050)
Category 1: Peer-reviewed literature

Investigating ecological relationships between predators and their environment is essential to understand the response of marine ecosystems to climate variability and change. This is particularly true in polar regions, where sea ice (a sensitive climate variable)…

Catch removals due to killer and sperm whale interactions across sub-Antarctic fisheries Working Group on Fish Stock Assessment, Hobart, Australia 7-18 October 2019, 2019 (Ref: 16975)
Category 2: International meeting papers

Fisheries are human activities that alter resource availability for species in marine ecosystems. While fisheries remove fish biomass, they may also provide new feeding opportunities to various marine predators. These species, depredating on catches directly on the fishing gear…

Elephant seal foraging success is enhanced in Antarctic coastal polynyas Proceedings of the Royal Society B - Biological Sciences, 2022 (Ref: 16578)
Category 1: Peer-reviewed literature

Antarctic polynyas are persistent open water areas which enable early and large seasonal phytoplankton blooms. This high primary productivity, boosted by iron supply from coastal glaciers, attracts organisms from all trophic levels to form a rich and diverse community.

Foraging habitats of top predators, and Areas of Ecological Significance, on the Kerguelen Plateau. The Kerguelen Plateau: marine ecosystem and fisheries, 2011 (Ref: 14718)
Category 1: Peer-reviewed literature

Avian and mammalian predators play a key role in the Kerguelen Plateau ecosystem, both with respect to structuring the marine community and its response to anthropogenic influences, such as climate change and commercial fisheries.

Colony-based foraging segregation by Antarctic fur seals at the Kerguelen Archipelago. Marine Ecology Progress Series, 2008 (Ref: 13845)
Category 1: Peer-reviewed literature

The foraging behaviour of conspecific female Antarctic fur seals (AFS) was compared … simultaneously at 2 breeding colonies at Iles Kerguelen (S Indian Ocean). A remnant colony at IIes … Nuageuses (IN)…

Variations in behavior and condition of a Southern Ocean top predator in relation to in situ oceanographic conditions Proceedings of the National Academy of Science, 2007 (Ref: 13380)
Category 1: Peer-reviewed literature

Responses by marine top predators to environmental variability … have previously been almost impossible to observe directly. By … using animal-mounted instruments simultaneously recording … movements, diving behavior, and in situ oceanographic properties…

Comparison of mass-transfer and isotopic dilution methods for estimating milk intake in Antarctic fur seal pups Polar Biology, 2004 (Ref: 13398)
Category 1: Peer-reviewed literature

The efficacy of a new mass-transfer method for … estimating milk intake was examined in Antarctic fur … seals (Arctocephalus gazella) at Iles Kerguelen. Our … method differed from previous mass-transfer approaches … in that we estimated milk-mass transfer as the maternal … mass lost (MML; kg)…
