8. Time budgets and foraging characteristics of lactating Antarctic fur seals

   (1) We investigated time allocation to parental care ashore and foraging at sea by lactating Antarctic fur seals at Bird Island, South Georgia, during 1988-89 and 1989-90 and related this […]

9. Mass changes and metabolism in territorial male Antarctic fur seals (Arctocephalus gazella)

   Energy expenditure of fasting territorial male Antarctic fur seals at South Georgia was measured by mass loss and analysis of carcass composition using tritium dilution in 1987 and 1988. Mean […]

10. Diving behaviour in relation to water temperature in the southern elephant seal: foraging implications

    A time-depth-temperature recorder provided a continuous record of diving by a female southern elephant seal in relation to water temperature for 27 days (1939 dives) after completion of moult. Mean […]

11. Environmental and physiological factors controlling the reproductive cycles of pinnipeds

    The reproductive pattern of pinnipeds is characterised by embryonic diapause, annual reproduction, and synchronous breeding cycles. Active gestation lasts about 8 months in most species, but the duration of embryonic […]

12. Changes in plasma progesterone and prolactin concentrations during the annual cycle and the role of prolactin in the maintenance of lactation and luteal development in the Antarctic fur seal (Arctocephalus gazella)

    Progesterone in Antarctic fur seals was undectable from 1–2 days before parturition to 4–6 days after parturition. There was a rapid increase in progesterone to 20 ng/ml between 6 and […]
