Table 3.
The strength of evidence for ecological models of variation in mating rate, measured under laboratory conditions, after controlling for variation in mating behaviour associated with sexual morphology. Model variables and AICc results are described in table 1. The set of models includes a baseline (intercept-only) model for comparison.
