Distance-based linear model (DistLM) of N-cycle processes against biotic (micro- and macrofauna) and abiotic factors.

DistLM analyses were run two times for every process separating microbial species richness and diversity in each model (processes run using 1Shannon diversity or 2OTU richness). Predictor variables subjected to a sequential step-wise selection procedure using the AIC criterion.aMGS = median grain size;bBPc = Bioturbation Potential of the Community;cPAP ratio = The ratio of phaeopigments to the sum of chl-a + phaeopigments [41].Distance-based linear model (DistLM) of N-cycle processes against biotic (micro- and macrofauna) and abiotic factors.
