AICc-based model selection to investigate the effect of group composition on ln-transformed mean group speed (MGS) and net displacement rate (NDR) using linear mixed-effects models.

Models included fission ID as a random effect between initial vs. post-fission groups (models including Origin) and between the smallest vs. largest post-fission groups (models including Post-fission group size). Group composition is indicated by either sex segregation (male-only, female-only vs. mixed sex groups) or the proportion of adult males or females.
