Long‐term warming effects on the microbiome andnifHgene abundance of a common moss species in sub‐Arctic tundra
Summary Bacterial communities form the basis of biogeochemical processes and determine plant growth and health. Mosses harbour diverse bacterial communities that are involved in nitrogen fixation and carbon cycling. Global climate change is causing changes in aboveground plant biomass and shifting s...
