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

Knowledge of soils in the permafrost region has advanced immensely in recent decades,
despite the remoteness and inaccessibility of most of the region and the sampling limitations …

The Arctic is a water-rich region, with freshwater systems covering about 16% of the northern
permafrost landscape. Permafrost thaw creates new freshwater ecosystems, while at the …

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

Microorganisms exist throughout the soil profile and those microorganisms living in deeper
soil horizons likely play key roles in regulating biogeochemical processes. However, the …

The paradigm that permafrost-affected soils show restricted mineral nitrogen (N) cycling in
favor of organic N compounds is based on the observation that net N mineralization rates in …

In the Arctic, environmental factors governing microbial degradation of soil carbon (C) in
active layer and permafrost are poorly understood. Here we determined the functional …

Microorganisms dominate terrestrial environments in the polar regions and Arctic soils are
known to harbour significant microbial diversity, far more diverse and numerous in the …

The subarctic region is highly responsive and vulnerable to climate change. Understanding
the structure of subarctic soil microbial communities is essential for predicting the response …

Thawing of permafrost soils is expected to stimulate microbial decomposition and respiration
of sequestered carbon. This could, in turn, increase atmospheric concentrations of …
