Co-occurrence network in the intermediate (a) and distal (b) wells. Each connection represents a strong positive and significant Spearman’s correlation (ρ > 0.6, P < 0.01) and the thickness of the connections is proportional to the correlation coefficient. The size of the nodes is proportional to the node degree (number of connections), and the node colours represent microbial phyla
