DOI: 10.1007/s00300-019-02560-x

Abstract: An adult male sub-Antarctic fur seal, Arctocephalus tropicalis, on Inaccessible Island in the Tristan da Cunha archipelago (TdC), was observed infested with goose barnacles, likely Lepas australis. Although adult females have been recorded to carry… read more here.

DOI: 10.1007/s00300-020-02688-1

Abstract: The most plausible hypothesis for declining population trends of some marine top predators at the northern extent of their breeding ranges in the Southern Ocean is that it results from environmental change. Sub-Antarctic fur seals… read more here.

DOI: 10.1007/s00300-021-02849-w

Abstract: Some top predator populations in the South Atlantic and South Indian oceans are in decline, presumably contingent upon reduced food availability, precipitated by climate change. This phenomenon impacts on the positions of major ocean frontal… read more here.

DOI: 10.1007/s00300-024-03325-x

Abstract: We analysed unpublished data on territory size and tenure in adult male sub-Antarctic fur seals Arctocephalus tropicalis recorded at Gough Island, Southern Ocean, during the 1975/76 austral summer breeding season. Adult males (n=15) remained on… read more here.

DOI: 10.1007/s10164-024-00811-x

Abstract: We recorded intra-sexual behaviour of adult male sub-Antarctic fur seals Arctocephalus tropicalis at Gough Island, Southern Ocean, during the 1975/76 summer breeding season. Our re-analysed data address male ‘contest competition’, which relates to the costs… read more here.

recommendations! Published in 2021 at "Scientific Reports"

DOI: 10.1038/s41598-021-93253-1

Abstract: Tracking studies of juveniles are rare compared to those of adults, and consequently little is known about the influence of intrinsic and extrinsic factors on activity during this critical life stage. We used hourly GPS… read more here.

DOI: 10.3389/fmicb.2025.1603500

Abstract: Comparative studies of microbial communities occupying different body sites in wild vertebrates are scarce, but they are crucial for advancing our understanding of the ecological and evolutionary factors shaping animal microbiomes. We therefore used a… read more here.

DOI: 10.3390/genes13030541

Abstract: Much debate surrounds the importance of top-down and bottom-up effects in the Southern Ocean, where the harvesting of over two million whales in the mid twentieth century is thought to have produced a massive surplus… read more here.
