Antarctic active volcanoes can disperse pyroclastic minerals at long distances, transporting
nutrients and microorganisms to the surrounding glacial environment. The sedimented …

The Antarctic continent hosts exceptional niches, making it an ideal environment for studying
polyextremophilic microorganisms. These organisms are uniquely shaped by the …

Glaciers constitute a polyextremophilic environment characterized by low temperatures, high
solar radiation, a lack of nutrients, and low water availability. However, glaciers located in …

Glaciers are populated by a large number of microorganisms including bacteria, archaea
and microeukaryotes. Several factors such as solar radiation, nutrient availability and water …

The Greenland Ice Sheet is a biome which is mainly microbially driven. Several different
niches can be found within the glacial biome for those microbes able to withstand the harsh …

Measurement of gases entrapped in clean ice from basal portions of the Taylor Glacier,
Antarctica, revealed that CO2 ranged from 229 to 328 ppmv and O2 was near 20% of the …

It has been demonstrated that the englacial ecosystem in volcanic environments is inhabited
by active bacteria. To know whether this result could be extrapolated to other Antarctic …

Little is known about the viability of eukaryotic microorganisms preserved in icy regions.
Here we report on the diversity of microbial eukaryotes in ice samples derived from four …

It has been demonstrated that the englacial ecosystem in volcanic environments is inhabited
by active bacteria. To know whether this result could be extrapolated to other Antarctic …

Microorganisms in Antarctica are recognized for having crucial roles in ecosystems
functioning and biogeochemical cycles. To explore the diversity and composition of …
