Vegetation structure determines the spatial variability of soil biodiversity across biomes

Abstract The factors controlling the spatial variability of soil biodiversity remain largely undetermined. We conducted a global field survey to evaluate how and why the within-site spatial variability of soil biodiversity (i.e. richness and community composition) changes across global biomes with c...
