Fig 1.
Elo ratings for adult females in eight social groups between January 2010 and July 2016.
Elo ratings were calculated using long-term dominance interactions dating back to the date of each group formation (or to 2000 for PAB group). For clarity data are only shown for the period 2010–2016. Each symbol denotes a female and each point represents an interaction between females, with lines between points representing the change in Elo rating for the two interacting females.

Mean, range, sample size (N) and coefficients of variation (CV) among females and males for the two morphological traits: Back breadth and body length.

Relationship between dominance rank and inter-birth interval duration.
Dominance rank is standardized between 0 (lowest rank) and 1 (highest rank). The area of the circles represents sample size (N = 29 inter-birth intervals; 16 adult females). The dashed line is the fitted model line and the shaded area is its 95% confidence intervals.
