Nitrogen (N) availability is thought to frequently limit terrestrial ecosystem processes, and
explicit consideration of N biogeochemistry, including biological N2 fixation, is central to …

Ecosystems in the far north, including arctic and boreal biomes, are a globally significant
pool of carbon (C). Global change is proposed to influence both C uptake and release in …

Biological nitrogen (N) fixation (BNF), an important source of N in terrestrial ecosystems,
plays a critical role in terrestrial nutrient cycling and net primary productivity. Currently, large …

Despite recent interest in linkages between above‐and below‐ground communities and
their consequences for ecosystem processes, much remains unknown about their …

The biological fixation of atmospheric nitrogen (N) is a major pathway for available N
entering ecosystems. In N-limited boreal forests, a significant amount of N2 is fixed by …

Biological nitrogen fixation represents the largest natural flux of new nitrogen (N) into
terrestrial ecosystems, providing a critical N source to support net primary productivity of …

Biological nitrogen fixation (BNF) performed by moss‐associated cyanobacteria is one of the
main sources of new nitrogen (N) input in pristine, high‐latitude ecosystems. Yet, the …

Moss‐associated cyanobacteria nitrogen (N2‐) fixation can contribute to support moss
growth and constitutes a major source of new N in boreal forest ecosystems. The biomass of …

Plant productivity is predicted to increase in northern latitudes as a result of climate warming;
however, this may depend on whether biological nitrogen (N)‐fixation also increases. We …

Summary Nitrogen (N2)‐fixing moss microbial communities play key roles in nitrogen
cycling of boreal forests. Forest type and leaf litter inputs regulate moss abundance, but how …
