Figure 4. Association indices for the Colobus angolensis
ruwenzorii core units at Nabugabo, Uganda that males transferred
between (solid lines) for the 3 months following each male dispersal
event from Aug. 2017 to May 2019. Dashed lines represent expected levels
of association, given how much these core units (i.e. those involved in
male transfers) continued to associate with other core units not
involved in the male dispersal event. (*) indicates association indices
that were significantly higher in the core units with male transfer than
would be expected at α= 0.05.
