Physical aggression received by painted chameleons increases with colour signal/behaviour mismatch. Physical aggression received by painted chameleons depends on the interaction between their external, experimentally manipulated colour and their overall level of aggression. Parameters calculated using GLMM with painted chameleon identity included as random effect and Poisson distribution. Estimate, slope estimate; s.e., standard error. Italicized values indicate significant effects.
