Grooming and aggression networks. The (a, b) grooming and (c, d) aggression networks for (a, c) 2010 and (b, d) 2011. Node colour represents partition membership where Evicted females are red, Resident females purple, matriline 004 females green and matriline 073 females blue. Colour intensity of the edge arrows indicates the relative weight of the interaction, with darker edges indicating greater intensity. Each network is force-directed using the Fruchterman–Reingold algorithm. Inset chord diagrams: width of chords represents the summation of interactions initiated by a given partition and directed at other partitions. Chords take the colour of the initiating partition.
