Co-occurrence and mutual exclusion network based on significant correlations (P ≤ 0.1) of relative abundance of major classified genera (each detected in at least 50% of the sample) of ruminal microbiota of pair-fed thermal neutral (PFTN) control cows and heat-stressed (HS) cows (A), and the genus-level nodes exclusively found in the PFTN cows and the HS cows (B). The size of the nodes represents the sum of the weights of the interactions connected. The exclusive nodes were marked as red asterisks within each exclusive microbial network. Blue and red lines indicate co-occurrence and mutual exclusion, respectively
