From: Protist communities are more sensitive to nitrogen fertilization than other microorganisms in diverse agricultural soils

Fig. 3

The networks visualize fertilization treatment (including no nitrogen addition (control), nitrogen addition (N), nitrogen + straw addition (NS)) effects on the co-occurrence pattern between protist, bacterial, and fungal taxa at family level in soils. The networks in (a) were constructed based on fertilization treatment of all soil types. The networks in (bd) were constructed based on fertilization treatment for each soil type. The node size is proportional to the abundance of taxa, and the nodes filled in blue are bacterial taxa, in pink are fungal taxa, and in gray are protist taxa. The edges are colored according to interaction types; positive correlations are labeled with green and negative correlations are coloured in red
