Spatial patterns in soil organic matter dynamics are shaped by mycorrhizosphere interactions in a treeline forest
Abstract 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 influ...
