...…composition in regulating multiple soil processes, soil microbial diversity also plays a pivotal role in maintaining ecosystem multifunctionality (Delgado-Baquerizo et al., 2017b, 2016; Wagg et al., 2014), corroborating the strong correlations between bacterial/archaeal/fungal richness/diversity…...

...Interestingly, no effects of microbial richness or diversity on the soil C process matrix or on microbial respiration or CUE were detected, in accordance with previous field study that showed no relation between basal respiration with bacterial richness (Delgado-Baquerizo et al., 2017b)....

...We also observed substantial associations between microbial richness/ diversity and soil enzyme patterns and single soil enzyme activities (Tables S6A and B), in line with findings from previous soil multifunctionality studies (Delgado-Baquerizo et al., 2017b, 2017a)....

...The positive effect of Solibacteres on the resistance of labile C mineralisation is consistent with results from previous studies suggesting that oligotrophic communities (sensu Fierer et al. 2007; Trivedi et al. 2013) promote the resistance of functions related to C cycle (de Vries & Shade 2013)....
