Foraging energetics of Antarctic fur seals in relation to changes in prey availability
account for the observed between-year difference in at-sea FMR of C. ursinus while foraging-trip duration ... lactating female Antarctic fur seals, Arctocephalus gazella, foraging at sea was measured in two years using ... doubly labeled water at South Georgia Island. There was no difference between years in mass gain, water ... influx, mass-specific field metabolic rate (FMR), or absolute FMR. Mean at-sea FMR over both years was ...
