F-values and p-values are given. “Social” refers to the composition of the social environment (i.e. homogeneous or heterogeneous) (see Methods). The Female Experiment–varying female body size; The Male Experiment–varying male body size; The Female-Male Experiment–varying both male and female body size. Bold–p–value ≤ 0.05.
