1. Bringing home the trash: Do colony-based differences in foraging distribution lead to increased plastic ingestion in Laysan albatrosses?

   When searching for prey, animals should maximize energetic gain, while minimizing energy expenditure by altering their movements relative to prey availability. However, with increasing amounts of marine debris, what once […]

2. Effects of post-breeding moult and energetic condition on timing of songbird migration into the tropics

   Each autumn billions of songbirds migrate between the temperate zone and tropics, but little is known about how events on the breeding grounds affect migration to the tropics. Here, we […]

3. Bunched black (and grouped grey) swans: Dissipative and non-dissipative models of correlated extreme fluctuations in complex geosystems

   I review the hierarchy of approaches to complex systems, focusing particularly on stochastic equations. I discuss how the main models advocated by the late Benoit Mandelbrot fit into this classification, […]

4. Warming constrains bacterial community responses to nutrient inputs in a southern, but not northern, maritime Antarctic soil

   We investigated the effects of increased soil temperature, water and nutrient availability on soil bacterial communities at Wynn Knolls on Signy Island (60 °S) in the northern maritime Antarctic and […]

5. High-latitude ocean and sea ice surface fluxes: Challenges for climate research

   Polar regions have great sensitivity to climate forcing; however, understanding of the physical processes coupling the atmosphere and ocean in these regions is relatively poor. Improving our knowledge of high-latitude […]

6. Use and abuse of alcohol and other drugs during the heroic age of Antarctic exploration

   During the heroic age of Antarctic exploration, there was much discussion on the role of alcohol. The explorers expected to be able to consume alcohol, and the expeditions were supported […]

7. When celibacy matters: Incorporating non-breeders improves demographic parameter estimates

   In long-lived species only a fraction of a population breeds at a given time. Non-breeders can represent more than half of adult individuals, calling in doubt the relevance of estimating […]

8. Significant reduction of cold temperature extremes at Faraday/Vernadsky station in the Antarctic Peninsula

   This study examines the daily observed temperature at the Faraday/Vernadsky station in the Antarctic Peninsula for the period February 1947 through January 2011. Faraday/Vernadsky is experiencing a significant warming trend […]

9. On estimating local climate sensitivity

   Climate sensitivity is commonly taken to refer to the equilibrium change in the annual mean global surface temperature following a doubling of the atmospheric carbon dioxide concentration. Evaluating this variable […]

10. Rapid climatic driven shifts of diatoms at high latitudes

    The composition of marine ecosystems is determined by spatial and temporal patterns of global biogeochemical cycles. Shifts in marine ecosystem composition driven by changes in climate can in turn affect […]

11. Predicting the distribution of a threatened albatross: The importance of competition, fisheries and annual variability

    The ability to predict the distribution of threatened marine predators is essential to inform spatially explicit seascape management. We tracked 99 individual black-browed albatrosses Thalassarche melanophris from two Falkland Islands’ […]

12. Rates and mechanisms of turbulent dissipation and mixing in the Southern Ocean: Results from the Diapycnal and Isopycnal Mixing Experiment in the Southern Ocean (DIMES)

    The spatial distribution of turbulent dissipation rates and internal wave field characteristics is analysed across two contrasting regimes of the Antarctic Circumpolar Current (ACC), using microstructure and finestructure data collected […]
