Long‐term warming effects on the microbiome and nifH gene abundance of a common moss species in sub‐Arctic tundra
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 species c...
