Figure 3. — Social unit sizes across three gorilla populations follow a consistent scaling relationship close to that observed in other mammalian species showing HSM. Social tier values 1–7 represent g1 (individuals), mother–offspring units, g2 (family units), g3 (dispersed extended family group), g4 (aggregated group), g5 (sub-population), and g6 (overall population). (a) For three separate populations Mbeli (blue), Lokoué (red), Maya Nord (purple) with their fitted exponentials shown by dashed lines. (b) For the mean of social unit sizes at each level from all populations, with dashed line indicating the fitted exponential (scaling ratio = 2.70, R² = 0.991, p = 6.37 × 10⁻¹⁰).
