Soil viruses are highly abundant and have important roles in the regulation of host dynamics
and soil ecology. Climate change is resulting in unprecedented changes to soil ecosystems …

The Arctic cryosphere is collapsing, posing overlap** environmental risks. In particular,
thawing permafrost threatens to release biological, chemical and radioactive materials that …

Methane (CH4) is produced in many natural systems that are vulnerable to change under a
warming climate, yet current CH4 budgets, as well as future shifts in CH4 emissions, have …

The physical and chemical changes that accompany permafrost thaw directly influence the
microbial communities that mediate the decomposition of formerly frozen organic matter …

Microbial decomposition of soil carbon in high-latitude tundra underlain with permafrost is
one of the most important, but poorly understood, potential positive feedbacks of …

Permafrost constitutes a major portion of the terrestrial cryosphere of the Earth and is a
unique ecological niche for cold-adapted microorganisms. There is a relatively high …

Permafrost represents a largely understudied genetic resource. Thawing of permafrost with
global warming will not only promote microbial carbon turnover with direct feedback on …

The Arctic is currently warming at unprecedented rates because of global climate change,
resulting in thawing of large tracts of permafrost soil. A great challenge is understanding the …

Microorganisms in cold ecosystems play a key ecological role in their natural habitats. Since
these ecosystems are especially sensitive to climate changes, as indicated by the worldwide …

Global atmospheric methane (CH 4) concentrations are now approaching 1800 ppbv as a
result of the growing imbalance between the net CH 4 emissions from natural and …
