Fig. 7.
Topological profiling of bacterial (a) and fungal (b) symbiont networks.
The circle represents the species, and the size of the circle represents the average abundance of the species; line represents the correlation between the two species, the thickness of the line represents the strength of the correlation, the color of the line: red represents a positive correlation, green represents a negative correlation.
