Individuals fall into distinct contacting clusters. A Dendrogram showing how individuals were clustered into four contacting clusters using hierarchical clustering: non-contacters (NC; n = 215), low-contacters (LC; n = 181), intermediate-contacters (IC; n = 166) and high-contacters (HC; n = 85). B Log weighted degree as a function of contacting cluster. Large circles are means; small circles are individuals; bars show plus or minus two standard deviations
