Most of the Earth's biosphere is characterized by low temperatures (< 5° C) and cold-
adapted microorganisms are widespread. These psychrophiles have evolved a complex …

Although Antarctica was once believed to be a sterile environment, it is now clear that the
microbial communities inhabiting the Antarctic continent are surprisingly diverse. Until the …

Bacteria grow and transform elements at different rates, and as yet, quantifying this variation
in the environment is difficult. Determining isotope enrichment with fine taxonomic resolution …

Background Winter carbon loss in northern ecosystems is estimated to be greater than the
average growing season carbon uptake and is primarily driven by microbial decomposers …

Bacterial diversity from McMurdo Dry Valleys in Antarctica, the coldest desert on earth, has
become more easily assessed with the development of High Throughput Sequencing (HTS) …

Imbalances in C: N: P supply ratios may cause bacterial resource limitations and constrain
biogeochemical processes, but the importance of shifts in soil stoichiometry are complicated …

The Antarctic continent is widely considered to be one of the most hostile biological habitats
on Earth. Despite extreme environmental conditions, the ice-free areas of the continent …

Microbial communities play a major role in the degradation of soil organic matter (SOM) in
soils. Despite its significance, the functional diversity of the highly diverse microbial …

The benthos in estuarine environments often experiences periods of regularly occurring
hypoxic and anoxic conditions, dramatically impacting biogeochemical cycles. How oxygen …

Highly adapted and often endemic microbial taxa inhabit soils and rocks of extremely cold
and dry Antarctic deserts. However, the source populations of these organisms have not yet …
