We ran models twice – first without including focal male weight (“Not controlling for male weight) and then with focal male weight (“Controlling for male 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.
