a The networks represent random matrix theory-based correlation models derived from all samples for each dataset, where nodes represent OTUs, and links between the nodes represent significant correlations. The node size is proportional to its degree, and the color indicates the abundance category (i.e., abundant, intermediate, and rare biospheres). The sample sizes for network analysis are as follows: Hangzhou Bay, 72; Plymouth Harbor, 66; coastal Sydney, 60; Dois Rios Estuary, 9; the Tara Oceans, 139. b A summary of the network links by the abundance categories of the associated OTUs. Source data are provided in the Source Data File.
