A Regression coefficients of variables explaining bacterial and eukaryotic richness (as estimated by the Abundance-based Coverage Estimator (ACE) on 16S rRNA gene data) from partial least square (PLS) models. B Results of multiple correlations using environmental variables and beta-diversity ordinations (non-parametric multidimensional scaling - NMDS) of bacterial and eukaryotic 16S rRNA gene data to evaluate community organization across measured gradients. Only statistically significant (p < 0.05) correlations between variables and community composition are given. The size of the bubbles is inverse to the p value while color indicates the correlation coefficient (R value). TP total phosphorus, TOC total organic carbon, TN total nitrogen, O2 oxygen concentrations, N2O N2O concentrations, N2O_sat N2O saturation, gl_dist distance from glacier, DOC dissolved organic carbon, CO2 CO2 concentrations, CO2_sat CO2 saturation, CH4 CH4 concentrations, CH4_sat CH4 saturation, C counts cell counts, bird bird impact, altitude.
