Extreme Solar Events: Setting up a Paradigm
The Sun is magnetically active and often produces eruptive events on different energetic and temporal scales. Until recently, the upper limit of such events was unknown and believed to be […]

Polar lake microbiomes have distinct evolutionary histories
Read more of: Polar lake microbiomes have distinct evolutionary historiesToward the poles, life on land is increasingly dominated by microorganisms, yet the evolutionary origin of polar microbiomes remains poorly understood. Here, we use metabarcoding of Arctic, sub-Antarctic, and Antarctic […]

Diving efficiency at depth and pre-breeding foraging effort increase with haemoglobin levels in gentoo penguins
Read more of: Diving efficiency at depth and pre-breeding foraging effort increase with haemoglobin levels in gentoo penguinsIndividual differences in oxygen storage and carrying capacity have been associated with fitness-related traits and, for air-breathing aquatic animals, to diving ability and foraging success. In winter, many seabirds must […]

Spatial, temporal, and demographic variability in patagonian toothfish (Dissostichus eleginoides) spawning from twenty-five years of fishery data at South Georgia
Read more of: Spatial, temporal, and demographic variability in patagonian toothfish (Dissostichus eleginoides) spawning from twenty-five years of fishery data at South GeorgiaPatagonian toothfish (Dissostichus eleginoides) are a commercially important species that support a longline fishery at the subantarctic island of South Georgia (CCAMLR Subarea 48.3). Understanding the life history of Patagonian […]

Investigating non-fungal eukaryotic diversity in snow in the Antarctic Peninsula region using DNA metabarcoding
Read more of: Investigating non-fungal eukaryotic diversity in snow in the Antarctic Peninsula region using DNA metabarcodingSnow is a unique microhabitat, despite being a harsh environment, multiple life forms have adapted to survive in it. While algae, bacteria and fungi are dominant microorganisms in Antarctic snow, […]
