Effect of oil palm plantations on social partner diversity in Macaca nemestrina. Shown are individual scores of partner diversity, i.e. the number of different affiliative partners per point time scan, in the forest and at the plantation edge. The dashed lines show the fitted model and the shaded areas its 95% confidence interval, conditional on continuous control predictors being on their average, and based on age-sex class, group and time of the day manually dummy coded and then centred. For visual clarity, observation values were averaged per individual, with circle areas corresponding to respective observation hours per focal animal (Total N = 1206 focal observations of 50 individuals (36 of AMY, 14 of VOL).
