Table 1.

Statistics of multi-linear and clustering analyses of the relationships between relative abundance of bacterial and fungal families and basal soil respiration, straw mineralization, and the priming effect. Analyses of relative abundance of bacteria, fungi, and bacteria and fungi get together.
