Virophage control of antarctic algal host–virus dynamics
Viruses are abundant ubiquitous members of microbial communities and in the marine environment affect population structure and nutrient cycling by infecting and lysing primary producers. AntarcticExpand
An integrative study of a meromictic lake ecosystem in Antarctica
In nature, the complexity and structure of microbial communities varies widely, ranging from a few species to thousands of species, and from highly structured to highly unstructured communities.Expand
Antarctic terrestrial life – challenging the history of the frozen continent?
Antarctica is a continent locked in ice, with almost 99.7% of current terrain covered by permanent ice and snow, and clear evidence that, as recently as the Last Glacial Maximum (LGM), ice sheetsExpand
Annual cycle of fCO2 under sea-ice and in open water in Prydz Bay, East Antarctica
The annual cycle of dissolved nutrients and the fugacity of CO2 (fCO2), calculated from the concentration of dissolved inorganic carbon (DIC) and pH, was studied over a 14-month long period (DecemberExpand
A global diatom database – abundance, biovolume and biomass in the world ocean
Phytoplankton identification and abundance data are now commonly feeding plankton distribution databases worldwide. This study is a first attempt to compile the largest possible body of dataExpand
Short Note: Natural seasonal variability of aragonite saturation state within two Antarctic coastal ocean sites
. The observed threefold changes in Ω ARAG shown here over a few months are of the same order of magnitude as those conditions used in artificial laboratory CO2 experiments. This makes theExpand
High level of intergenera gene exchange shapes the evolution of haloarchaea in an isolated Antarctic lake
Significance Horizontal gene exchange across species boundaries is considered infrequent relative to vertical inheritance that maintains species coherence. However, haloarchaea living in hypersalineExpand
Metagenomic insights into strategies of carbon conservation and unusual sulfur biogeochemistry in a hypersaline Antarctic lake
Organic Lake is a shallow, marine-derived hypersaline lake in the Vestfold Hills, Antarctica that has the highest reported concentration of dimethylsulfide (DMS) in a natural body of water. ToExpand
Vulnerability of Polar Oceans to Anthropogenic Acidification: Comparison of Arctic and Antarctic Seasonal Cycles
Polar oceans are chemically sensitive to anthropogenic acidification due to their relatively low alkalinity and correspondingly weak carbonate buffering capacity. Here, we compare unique CO2 systemExpand
Evidence for a lacustrine faunal refuge in the Larsemann Hills, East Antarctica, during the Last Glacial Maximum
Aim There is no previous direct evidence for the occurrence of lacustrine refuges for invertebrate fauna in Antarctica spanning the Last Glacial Maximum (LGM). In the absence of verified LGMExpand
