1. Initial results from light level geolocator trials on Ruddy Turnstone Arenaria interpres reveal unexpected migration route

   With the development of archival light level geolocators weighing only 1 g, their deployment on medium size waders is now possible. Trials showed that attachment via leg flag rather than […]

2. Lévy flight search patterns of wandering albatrosses

   LéVY flights are a special class of random walks whose step lengths are not constant but rather are chosen from a probability distribution with a power-law tail. Realizations of Lévy […]

3. Anomalous fluctuations in the dynamics of complex systems: from DNA and physiology to econophysics

   We discuss examples of complex systems composed of many interacting subsystems. We focus on those systems displaying nontrivial long-range correlations. These include the one-dimensional sequence of base pairs in DNA, […]

5. 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 […]

6. 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 […]

7. 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, […]

8. 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 […]

9. 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 […]

10. 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 […]

11. 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 […]

12. 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 […]
