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 …

The Arctic region is a unique environment, subject to extreme environmental conditions,
shaping life therein and contributing to its sensitivity to environmental change. The Arctic is …

Snow environments can occupy over a third of land surface area, but little is known about
the dynamics of snowpack bacteria. The effect of snow melt on bacterial community structure …

Modelling the development of soils in glacier forefields is necessary in order to assess how
microbial and geochemical processes interact and shape soil development in response to …

The aggregation of surface debris particles on melting glaciers into larger units (cryoconite)
provides microenvironments for various microorganisms and metabolic processes. Here we …

Low nitrogen availability in the high Arctic represents a major constraint for plant growth,
which limits the tundra capacity for carbon retention and determines tundra vegetation types …

Northern permafrost soils contain important carbon stocks. Here we report the long-term
response of carbon stocks in high Arctic dwarf shrub tundra to short-term, low-level nutrient …

The central Arctic is within the range of air pollution transported from industrial areas of
Eurasia and North America. A poor network of weather stations means that there is limited …

Low nitrogen (N) availability in the Arctic and Subarctic constrains plant productivity,
resulting in low litter inputs to soil. Increased N availability and litter inputs as a result of …

Arctic snowpacks are often considered as chemical reactors for a variety of chemicals
deposited through wet and dry events, but are overlooked as potential sites for microbial …
