Pairwise correlation of log₁₀ relative abundances for each microbial taxa between different preservation methods within sampling rounds. Correlations for sampling round 1 are given in the first column (a,c,e) and correlations for sampling round 2 are given in the second column (b,d,f). Each label in the scatter plots gives the pairwise correlation estimate (between the two methods on the x-axis compared to the two methods marked on the y-axis) in log₁₀ relative abundances of each taxon for each sampling round. Taxon labels are colored based on whether the taxon is archaeal (blue), bacterial with a gram-positive wall (black) or bacterial with a gram-negative wall (green). The size of the taxon labels on the plots are proportional to the mean relative abundance of each taxon
