Microbial co‐occurrence analysis patterns. (a) The distribution of C‐scores, a measure of species co‐occurrence, is shown here with OTUs aggregated at the genus level. As indicated by the arrow, the actual C‐score is significantly lower than that of the simulated communities, indicating a nonrandom species assembly process. (b) Network analysis reveals a lack of microbial competition in the Ixodes pacificus microbiome. The interaction network shows the pairwise correlations between all OTUs (genera) found across all samples and treatments. Nodes represent genera found in the microbiome and are colored by phylum. Edges represent significant pairwise correlations between genera. Red edges denote negative correlations, and green edges denote positive correlations
