FIG 3.

Density plots for the degree of NCLDV nodes in co-occurrence networks. The degree of an NCLDV node is given by the associations between this node and eukaryotes in the networks. The numbers of NCLDV nodes are given at the top of the density values. (A) Positive degree (number of positive associations per node) for NCLDV nodes in five size fraction networks. (B) Negative degree (number of negative associations per node) for NCLDV nodes in five size fraction networks. Size fractions are presented in μm. NCLDV nodes with degree = 1 and degree > 1 are separated using a vertical line, and the number of nodes is given.
