  1. Bold: P < 0.05. a) Generalized linear mixed model (GLMM): influence of predictors on vertex strength centrality and deviation from edge weight disparity subsequent to re-socialisation of the ex-laboratory chimpanzees. b) GLMM: influence of predictors on vertex strength centrality and deviation from edge weight disparity during the second year of group-life of the ex-laboratory chimpanzees. (Best models were chosen according to comparisons of cAIC’s).
