Dispersal of male and female Antarctic fur seals (Arctocephalus gazella)
TLDR
Analysis of foraging locations of adult male and female Antarctic fur seals in the Scotia Sea during the postbreeding period suggests that these fur seals are targeting the most abundant exploitable prey.
International policies to reduce plastic marine pollution from single-use plastics (plastic bags and microbeads): A review.
TLDR
Recommendations to further reduce single-use plastic marine pollution include research to evaluate effectiveness of bans and levies to ensure policies are having positive impacts on marine environments, and education and outreach to reduce consumption of plastic bags and microbeads at source.
Seasonal occurrence and diet of leopard seals ( Hydrurga leptonyx ) at Bird Island, South Georgia
TLDR
Seasonal haul-out patterns and diet of individually marked leopard seals were investigated at Bird Island, South Georgia during the 1983–96 winters, finding considerable inter-annual variation in abundance.
Foraging responses of Antarctic fur seals to changes in the marine environment
TLDR
Females appeared to match pup demands by increasing both time feeding at sea and energy delivery to the pup on land, and the importance of sea surface temperature and duration of night in multiple regression models suggested that physical factors were also important in explaining the seasonal pattern of fur seal foraging behaviour.
COVID-19 pandemic repercussions on the use and management of plastics.
TLDR
There is a need to assess alternatives that allow reductions of PPE and reinforce awareness on the proper public use and disposal, and assessment of contamination and impacts of plastics driven by the pandemic will be required once the outbreak ends.
Variation in foraging effort by lactating Antarctic fur seals: response to simulated increased foraging costs
TLDR
It is concluded that behavioral adjustments at the scale of individual dives allowed mothers in the treatment group to compensate for the additional foraging costs, and pup growth rate appears to be less sensitive to the foraging conditions experienced by mothers than foraging trip duration.
Rethinking and optimising plastic waste management under COVID-19 pandemic: Policy solutions based on redesign and reduction of single-use plastics and personal protective equipment
TLDR
The sudden increase in plastic waste and composition due to the COVID-19 pandemic underlines the crucial need to reinforce plastic reduction policies and to implement them into action without delays, to scale up in innovation for sustainable and green plastics solutions and to develop dynamic and responsive waste management systems immediately.
Marine debris surveys at Bird Island, South Georgia 1990–1995
The Antarctic marine environment has relatively few direct sources of man-made marine debris; however, there is concern over the dangers posed to wildlife by increasing amounts of such debris.
Status of southern elephant seals at South Georgia
Approximately 54% of the world population of southern elephant seals (Mirounga leonina) breeds at South Georgia. A partial survey in 1951 and a complete survey in 1985, together with counts at
Can marine mammals be used to monitor oceanographic conditions?
TLDR
Time–depth recorders programmed to record temperature were deployed on female Antarctic fur seals at Bird Island, South Georgia during the breeding seasons 1994 to 1998, suggesting that fur seals travelled northwards from South Georgia towards the warmer waters of the Polar Front.
