We ran models twice – first without including focal female weight (“Not controlling for female weight) and then with focal female weight (“Controlling for female weight”). Results are from mixed models fitted in ASReml‐R. Factors related to characteristics of competitors were fit as conditional effects. F statistics are conditional and taken from Wald's test. p‐values < .05 are shown in bold. Shaded rows show the effects of primary interest.
