Spatial patterns in soil organic matter dynamics are shaped by mycorrhizosphere interactions in a treeline forest
Aims In the Swedish sub-Arctic, mountain birch (Betula pubescens ssp. czerepanovii) forests mediate rapid soil C cycling relative to adjacent tundra heaths, but little is known about the role of individual trees within forests. Here we investigate the spatial extent over which trees influence soil p...
