2. Diversity of toxin and non-toxin containing cyanobacterial mats of meltwater ponds on the Antarctic peninsula: a pyrosequencing approach

   Despite their pivotal role as primary producers, there is little information as to the diversity and physiology of cyanobacteria in the meltwater ecosystems of polar regions. Thirty cyanobacterial mats from […]

3. The importance of geomagnetic field changes versus rising CO2 levels for long-term change in the upper atmosphere

   The Earth’s upper atmosphere has shown signs of cooling and contraction over the past decades. This is generally attributed to the increasing level of atmospheric CO2, a coolant in the […]

4. Commonness and rarity in the marine biosphere

   Explaining patterns of commonness and rarity is fundamental for understanding and managing biodiversity. Consequently, a key test of biodiversity theory has been how well ecological models reproduce empirical distributions of […]

5. Global diversity and oceanic divergence of humpback whales (Megaptera novaeangliae)

   Humpback whales (Megaptera novaeangliae) annually undertake the longest migrations between seasonal feeding and breeding grounds of any mammal. Despite this dispersal potential, discontinuous seasonal distributions and migratory patterns suggest that […]

6. Survival in macaroni penguins and the relative importance of different drivers: individual traits, predation pressure and environmental variability

   1. Understanding the demographic response of free-living animal populations to different drivers is the first step towards reliable prediction of population trends. 2. Penguins have exhibited dramatic declines in population […]

7. A cool temperate climate on the Antarctic Peninsula during the latest Cretaceous and early Paleogene

   Constraining past fluctuations in global temperatures is central to our understanding of the Earth’s climatic evolution. Marine proxies dominate records of past temperature reconstructions, whereas our understanding of continental climate […]

8. Contrasting strategies of resistance vs. tolerance to desiccation in two polar dipterans

   Low water availability is one of the principal stressors for terrestrial invertebrates in the polar regions, determining the survival of individuals, the success of species and the composition of communities. […]

9. Large mixing ratios of atmospheric nitrous acid (HONO) at Concordia (East Antarctic plateau) in summer: a strong source from surface snow?

   During the austral summer 2011/2012 atmospheric nitrous acid was investigated for the second time at the Concordia site (75°06′ S, 123°33′ E) located on the East Antarctic plateau by deploying […]

10. Post-fledging dispersal of King Penguins (Aptenodytes patagonicus) from two breeding sites in the South Atlantic

    Most studies concerning the foraging ecology of marine vertebrates are limited to breeding adults, although other life history stages might comprise half the total population. For penguins, little is known […]

11. Absence of a Medieval Climate Anomaly, Little Ice Age and twentieth century warming in Skarvsnes, Lützow Holm Bay, East Antarctica

    Palaeoclimate changes, such as the Medieval Climate Anomaly and the Little Ice Age, are well-defined in the Northern Hemisphere during the past 2000 years. In contrast, these anomalies appear to […]

12. Are the Antarctic dipteran, Eretmoptera murphyi, and Arctic collembolan, Megaphorura arctica, vulnerable to rising temperatures?

    Polar terrestrial invertebrates are suggested as being vulnerable to temperature change relative to lower latitude species, and hence possibly also to climate warming. Previous studies have shown Antarctic and Arctic […]
