Terrestrial Spatial Distribution and Summer Abundance of Antarctic Fur Seals (Arctocephalus gazella) Near Palmer Station, Antarctica, From Drone Surveys [PDF]

Ecology and Evolution
The shifting climatic regime of maritime Antarctica is driving complex changes across trophic levels that are manifesting differentially across its resident species and regions. Land‐breeding pinnipeds have increased their seasonal attendance near Palmer

Individual foraging strategies reveal niche overlap between endangered galapagos pinnipeds. [PDF]

PLoS ONE, 2013
Most competition studies between species are conducted from a population-level approach. Few studies have examined inter-specific competition in conjunction with intra-specific competition, with an individual-based approach.

Wintertime overlaps between female Antarctic fur seals (Arctocephalus gazella) and the krill fishery at South Georgia, South Atlantic.

PLoS ONE, 2021
The diet of Antarctic fur seals (Arctocephalus gazella) at South Georgia is dominated by Antarctic krill (Euphausia superba). During the breeding season, foraging trips by lactating female fur seals are constrained by their need to return to land to ...

Using accelerometers to develop time-energy budgets of wild fur seals from captive surrogates [PDF]

PeerJ, 2018
Background Accurate time-energy budgets summarise an animal’s energy expenditure in a given environment, and are potentially a sensitive indicator of how an animal responds to changing resources. Deriving accurate time-energy budgets requires an estimate

Nasopulmonary mites (Halarachnidae) of coastal Californian pinnipeds: Identity, prevalence, and molecular characterization

International Journal for Parasitology: Parasites and Wildlife, 2021
Mites from the family Halarachnidae Oudemans 1906 are obligate endoparasites that colonize the respiratory tracts of free-living and captive marine mammals.

First-Year Survival of Northern Fur Seals (Callorhinus ursinus) Can Be Explained by Pollock (Gadus chalcogrammus) Catches in the Eastern Bering Sea

Journal of Marine Science and Engineering, 2021
The Pribilof northern fur seal (Callorhinus ursinus) herd in the eastern Bering Sea has declined by ~70% since the 1970s, for elusive reasons. Competition for pollock (Gadus chalcogramma) with the commercial fishery has been suspected as a contributing ...

Sustained reduction in numbers of Australian fur seal pups: Implications for future population monitoring

PLoS ONE, 2022
Fur seal populations in the Southern Hemisphere were plundered in the late 1700s and early 1800s to provide fur for a clothing industry. Millions of seals were killed resulting in potentially major ecosystem changes across the Southern Hemisphere, the ...

The behavioural response of Australian fur seals to motor boat noise. [PDF]

PLoS ONE, 2012
Australian fur seals breed on thirteen islands located in the Bass Strait, Australia. Land access to these islands is restricted, minimising human presence but boat access is still permissible with limitations on approach distances. Thirty-two controlled

Factors that influence Cape fur seal predation on Cape gannets at Lambert’s Bay, South Africa [PDF]

PeerJ, 2022
Seabird populations experience predation that can impact their breeding density and breeding success. The Cape gannet Morus capensis is endemic to the Benguela upwelling ecosystem and is classified as Endangered by the IUCN.

Comparative Microbial Community Analysis of Fur Seals and Aquaculture Salmon Gut Microbiomes in Tasmania

Oceans, 2023
In Tasmania, Australian fur seals (Arctocephalus pusillus doriferus) regularly interact with Atlantic salmon (Salmo salmar L.) aquaculture lease operations and opportunistically consume fish. The microbial communities of seals and aquaculture salmon were
