(a) The correlation between the 16S rRNA gene sequences detected and all 71 C sources used before and after invasion; (b) The correlation between those taxa found to increase at least 1% in at least two of six diversity treatments upon invasion (see Fig. 2a) and the community-exclusive carbon sources upon invasion. RELATE tests were used to calculate the strength of the correlation, Rho, using Spearman’s correlation
