Table 1 The relative contribution (%) of each of the eight root traits to the variation in root mass loss for single-species treatments and two-species mixtures (based on community-weighted mean (CWM) traits) using hierarchical partitioning analyses (HPA), and the relationships between CWM trait and mass loss for single-species and two-species mixture using linear regression
From: Root mixing effects on belowground decomposition depend on mycorrhizal type
