Stable isotopes document inter- and intra-specific variation in feeding ecology of nine large southern Procellariiformes
Read more of: Stable isotopes document inter- and intra-specific variation in feeding ecology of nine large southern ProcellariiformesInvestigating the foraging ecology of seabirds is especially challenging given their wide-ranging movements and the practical difficulties of obtaining unbiased information on their feeding behavior. Despite the development of animal-borne […]

The terrestrial and freshwater invertebrate biodiversity of the archipelagoes of the Barents Sea; Svalbard, Franz Josef Land and Novaya Zemlya
Read more of: The terrestrial and freshwater invertebrate biodiversity of the archipelagoes of the Barents Sea; Svalbard, Franz Josef Land and Novaya ZemlyaArctic terrestrial ecosystems are generally considered to be species poor, fragile and often isolated. Nonetheless, their intricate complexity, especially that of the invertebrate component, is beginning to emerge. Attention has […]

A new estimate of the adopted gravity value at Rothera Station, Antarctic Peninsula
Read more of: A new estimate of the adopted gravity value at Rothera Station, Antarctic PeninsulaBecause of the lack of a definitive air link to an international gravity base station, the Antarctic Peninsula gravity network was originally, and still is, tied to the Potsdam gravity […]
