Additional file 4 of The yellow perch (Perca flavescens) microbiome revealed resistance to colonisation mostly associated with neutralism driven by rare taxa under cadmium disturbance

Additional file 4: Table S4. Summary of correlation network features in host and water microbial communities. The networks of gut microbial communities are composed of 30, 46, 65 of CC (connected components or hubs), respectively in Control, CV, and CC groups (see sheet 1). Therefore, the nodes number (NN) was lower in the Control group (ControlNN: 410) compared to Cd regimes networks (CVNN:488; CCNN:526). On the contrary, an average of neighbours (AN) was higher in the Control network (Control AN: 4) than in Cd groups networks (CVAN:2.98; CCAN:2.82). Skin microbial networks were composed of 47, 10, 3 of CC (connected components), respectively in Control, CV, and CC groups (see sheet 1). The number of CC was inversely proportional to nodes number, and low in Control group network (ControlNN: 651) in comparison with Cd networks (CV NN: 661; CC NN:759). Similarly, the average of neighbours (AN) was lower in the Control network (Control AN: 4) compared to Cd group networks (CVAN: 10.7; CCAN: 24.6). This high connectivity in CV and CC at T1 was proportional to the high percentage of strong negative correlations (R neg. Corr. < − 0.6; B-H p-value
