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 …

Warming-induced microbial decomposition of organic matter in permafrost soils constitutes a
climate-change feedback of uncertain magnitude. While physicochemical constraints on soil …

Many biotechnological applications deal with nitrification, one of the main steps of the global
nitrogen cycle. The biological oxidation of ammonia to nitrite and further to nitrate is critical to …

The Arctic is nutrient limited, particularly by nitrogen, and is impacted by anthropogenic
global warming which occurs approximately twice as fast compared to the global average …

Crop rotation is a common farmland management measure, which can effectively improve
soil permeability and soil fertility, reduce crop diseases and pests, and affect microbial …

The distinct climatic and geographical conditions make high‐altitude permafrost on the
Tibetan Plateau suffer more severe degradation than polar permafrost. However, the …

Chemolithoautotrophic production of nitrate is accomplished by the polyphyletic functional
group of nitrite‐oxidizing bacteria (NOB). A widely distributed and important NOB clade in …

Arctic tundra fires have been increasing in extent, frequency and intensity and are likely
impacting both soil nitrogen (N) and phosphorus (P) cycling and, thus, permafrost ecosystem …

Increased nitrogen (N) input from natural factors and human activities may negatively impact
the health of marsh wetlands. However, the understanding of how exogenous N affects the …

Permafrost-affected tundra soils are large carbon (C) and nitrogen (N) reservoirs. However,
N is largely bound in soil organic matter (SOM), and ecosystems generally have low N …
