Temporary streams are characterized by the alternation of dry and wet hydrological phases,
creating both a harsh environment for the biota as well as a high diversity of opportunities for …

Antarctica is arguably the world's most important continent for influencing the Earth's climate
and ocean ecosystem function. The unique physico-chemical properties of the Southern …

Psychrophilic (cold-adapted) microorganisms make a major contribution to Earth's biomass
and perform critical roles in global biogeochemical cycles. The vast extent and …

Microorganisms inhabit very different soil habitats in the ice-free areas of Antarctica, playing
a major role in nutrient cycling in cold environments. We studied the soil characteristics and …

Antarctic continent comprises diverse ecosystems like snow, glacier ice, sea ice, melt pools,
glacial soils, supraglacial and subglacial lakes that accommodate numerous microbial and …

Cyanobacteria are commonly thought of as microbial phototrophs that are characteristic of
warm water environments such as hot springs (Steunou et al., 2006), stratified lakes during …

River and stream biofilms in mediterranean fluvial ecosystems face both extreme
seasonality as well as arrhythmic fluctuations. The hydrological extremes (droughts and …

The global biogeography of microorganisms remains poorly resolved, which limits the
current understanding of microbial resilience toward environmental changes. Using high …

Cyanobacteria often account for a large and sometimes dominant fraction of phototrophic
biomass and primary production in high latitude lakes, ponds, streams and wetlands …

Soil‐dominated ecosystems, with little or no plant cover (ie deserts, polar regions, high‐
elevation areas and zones of glacial retreat), are often described as 'barren', despite their …
