NB, Networks and sub-networks include OTUs and environmental factors. Di = Network diameter. De = Network density. Largest clique = size of the largest clique(s) in the network, and in brackets, the number of them. Mod = Network modularity inferred using edge betweenness
*Includes nodes and edges shared between pico- and nanoplankton
^** Includes nodes and edges shared between bacteria and protists. Random ER network: follows the Erdős-Rényi model. Random WS network: “Small world” random network (Watts-Strogatz model). Random BA network: Scale free-random network (Barabási-Albert model)
