Supplementary Table 2. Parameters of the regression models fitted to the log-log transformed rank-abundance curves, represented by the equation log10y = a log10x + b, where a is the slope and b is the intercept. The slopes of the models differed significantly between suspended and biofilm communities (Student’s T-test, p < 0.001, n = 6); the slopes of bulk and active communities did not differ significantly.
