For treatment abbreviations see Table 1 and for an explanation of network topographical parameters see network community modeling in the results section. For network taxonomy, node # is the total number of nodes or OTUs in a given order for a network. The relative recovery of nodes is the summation of mean relative recoveries of the nodes within the order from P and CP or U and W communities.
