Correlation network analysis using SPIEC-EASI. a The ecological correlation network shows two groups of OTUs that are negatively correlated with each other. One group includes OTUs identified as enriched in COPD animals (COPD+) and the other includes OTUs enriched in non-COPD animals (COPD−). Each node represents an OTU and is colored by its assigned taxonomy. Green edges represent positive correlation between OTUs and red represent negative correlation. b Negative edges have been removed to show that the two groups have no positive correlations with each other. This separation emphasizes the shift in community composition that occurred when an animal developed COPD
