Figure S3. Social network map of mouse lemurs based on trapping data and louse exchanges. This figure represents the social contacts based on trapping data alone (black dashed line), based on louse transfers (dotted blue line), and contacts that occurred based on both trapping data and louse exchange data (solid purple line). 28 contacts were predicted based on trap locales, and 21 contacts were seen according to louse transfer data. Of the 21 louse exchange contacts, 8 of those were also paired based on trapping data; however, 13 lemur contacts based on louse exchanges can not be explained by trapping data. Of the 8 pairs with overlapping trap and louse contacts, 5 of those pairs belong to one individual (Mam), the same individual found to range widely throughout the trapping transect. These data suggests that while some lemur-lemur contacts may be predicted by trapping data, a majority of the louse exchanges seen in this study could not have been predicted based on trapping data alone. Additionally, the lemurs with the highest eigenvector centrality scores (indicating how well a lemur is connected to other lemurs) differed when calculating networks based on trapping and louse marking data separately. This means that calculating a social network based on trapping data alone would not have exposed the lemur with the most social contacts (Nap) as was revealed using louse marking data.
