Geographical, temporal, and individual‐based differences in the trophic ecology of female Cape fur seals
Sign Up to like & getrecommendations! Published in 2023 at "Ecology and Evolution"
DOI: 10.1002/ece3.9790
Abstract: Abstract Information on resource use and trophic dynamics of marine predators is important for understanding their role in ecosystem functioning and predicting population‐level responses to environmental change. Where separate populations experience different local environmental conditions,… read more here.

Canine morphometrics as a tool for distinguishing species, sex, and age class in Southern Ocean fur seals
Sign Up to like & getrecommendations! Published in 2022 at "Journal of Morphology"
DOI: 10.1002/jmor.21521
Abstract: Carcasses resulting from natural mortalities are invaluable for use in scientific studies, provided species, sex, and age class are known. When such data are unavailable, identifying skeletal remains is necessary if one is to use… read more here.

Fish prey of sub-Antarctic fur seals Arctocephalus tropicalis at the Tristan da Cunha Islands, South Atlantic Ocean
Sign Up to like & getrecommendations! Published in 2021 at "Polar Biology"
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.

Fur Seals Suppress REM Sleep for Very Long Periods without Subsequent Rebound
Sign Up to like & getrecommendations! Published in 2018 at "Current Biology"
DOI: 10.1016/j.cub.2018.05.022
Abstract: Virtually all land mammals and birds have two sleep states: slow-wave sleep (SWS) and rapid eye movement (REM) sleep [1, 2]. After deprivation of REM sleep by repeated awakenings, mammals increase REM sleep time [3],… read more here.

DOI: 10.1016/j.marpolbul.2021.112759
Abstract: Marine pollution is increasing, and pinnipeds are commonly affected by entanglement in waste. We investigated entanglement rates, common materials, and the demographic profile of Cape fur seals (Arctocephalus pusillus pusillus) affected at two Namibian colonies.… read more here.

DOI: 10.1093/conphys/coz103
Abstract: Abstract Quantifying metabolic rates and the factors that influence them is key to wildlife conservation efforts because anthropogenic activities and habitat alteration can disrupt energy balance, which is critical for reproduction and survival. We investigated… read more here.

Eye state asymmetry during aquatic unihemispheric slow wave sleep in northern fur seals (Callorhinus ursinus)
Sign Up to like & getrecommendations! Published in 2019 at "PLoS ONE"
DOI: 10.1371/journal.pone.0217025
Abstract: Unihemispheric slow wave sleep (USWS) is a unique form of sleep in which one brain hemisphere maintains low voltage electrical activity indicative of waking while the opposite exhibits slow wave electrical activity indicative of sleep.… read more here.
