The effects of sexual selection treatment, IPI, and their interaction on the response variable (mating latency or mating probability) were tested using likelihood ratio tests. Treatment is the sexual selection treatment (E is for polyandrous and M for monogamous), IPI is the artificial song tested (EE-like, E-like, M-like, or persimilis-like IPI), β is the model estimate, LR is the likelihood ratio statistics, and P is the P-value with bolded values being significant.
