Table S2. Model-averaged results based on SAR error (err)and SAR lagged (lag)models for the effect of structural (locations and zone) and environmental (AGS and Sorting) factors on gastrotrichs,macrodasyid and chaetonotid richness. Coefficients, their SEs, z-, p- values showed for each level of the factor. The first alphabetically level of each factor is used as intercept, and all subsequent levels are tested against the first. The remaining coefficients are differences from the mean. Results with z-values > 2.0 are shown in bold. For SAR error model,the lambda () representes the spatial structure (W) in the spatially dependent error term. For SAR lagged model,the rho () representesa term (W) for the spatial autocorrelation in the response variable (see Kissling and Carl, 2008).
