Interaction networks and behavioral analysis from trajectory data. (A) Example of a social network graph created from directed, pairwise initiator–responder counts. Node color denotes network (out-edges Katz) centrality of dominant (Dom) and subordinate (Sub) group members. (B) Aggregation of all individuals from the routine social interaction recordings showing the effect of social status on network centrality (network randomization test, P < 0.001). (C) Onset of speed events across all dominant and subordinate male event initiations (delay = 0) and responses (delay > 0). Dominant individuals were found to be more frequently the initiators of events than subordinates (network randomization test, P < 0.001). (D) Representative examples of speed traces of dominant and subordinate males. Upper represents onset and duration of speed events that exceed a 95% threshold of all speeds (v95%).
