  1. For each explanatory variable (sampling site, size, and interactions between these two factors), the portion of variation accounted for by each variable and the p value for statistical significance of the variable are expressed. Sampling site refers to the specific location for each sample (i.e., River A vs. River B). For this analysis, only large and small bacteria groups were included for size (“All bacteria” was excluded from analysis). Large bacteria is the HNA-dominated community collected on a 0.4 µm filter, and Small bacteria is the LNA-dominated community in the 0.4 µm filtrate, collected on a 0.2 µm filter
