5. Survival of sub-zero temperatures by two South Georgian beetles (Coleoptera, Perimylopidae)

   The ability of adults and larvae of two species of perimylopid beetles (Hydromedion sparsutum, Perimylops antarcticus) to survive sub-zero temperatures was studied at Husvik, South Georgia in summer during October–December […]

6. Long-term population studies of seabirds

   Long-term studies of seabirds, some now 30–40 years old, have begun to reveal significant age-related changes in the survival and reproduction o f these long-lived animals. Evidence for density-dependent regulation […]

7. Dinoflagellate cysts from the Marambio Group (Upper Cretaceous) of Humps Island

   Thirty samples from two sections on south-western Humps Island, James Ross Basin, northern Antarctic Peninsula, contain moderately diverse dinoflagellate cyst assemblages deposited in shallow shelf, open marine conditions. Assemblages contain […]

8. The influence of global and local atmospheric pollution on the chemistry of Antarctic snow and ice

   The Antarctic ice sheet is the main sink for atmospheric pollution reaching the Antarctic atmosphere from other continents. The ice preserves a historical record of the atmosphere that can be […]

9. Diving Pattern and Performance in Nonbreeding Gentoo Penguins (Pygoscelis papua) during Winter

   We studied diving patterns and performance (dive depth, duration, frequency and organization during the foraging trip) in relation to diet in nonbreeding Gentoo Penguins (Pygoscelis papua) over 59 days (involving […]

10. Breeding and moulting fasts in macaroni penguins: Do birds exhaust their fat reserves?

    1. Plasma concentrations of urea, uric acid and total lipid were compared in pre- and late-fast breeding and moulting macaroni penguins (Eudyptes chrysolophus) to test the hypothesis that birds exhaust […]

11. Diving pattern and performance in relation to foraging ecology in the gentoo penguin,Pygoscelis papua

    We present data on diving pattern and performance (dive depth, duration, frequency and organization during the foraging trip) in gentoo penguins Pygoscelis papua, obtained using time-depth recorders (n= 9 birds, […]

12. Annual variation in return rate, mate and nest-site fidelity in breeding Gentoo and Macaroni Penguins

    Annual variation in return rate of breeding birds, mate and nest-site fidelity was studied in the resident Gentoo (Pygoscelis papua) and migratory Macaroni (Eudyptes chrysolophus) Penguin from 1986 to 1990 […]
