Microbial interactions visualized through microbial co-occurrence networks. a Microbial interactions are influenced by environmental factors and are separated into positive, neutral, and negative interactions types. b Microbial co-occurrence and co-exclusion networks help visualizing microbial interactions. In such networks, nodes usually represent taxa of microorganisms, and edges represent statistically significant associations between nodes. Green edges usually stay for positive interactions, while red edges visualize negative interactions between the microorganisms. c Testing of the hypotheses resulted from the network analyses in relevant model systems is required for a comprehensive study of microbial interactions
