Results of the generalised additive mixed model (GAMM) predicting the effect of degree of mismatch, flower head density and flower head display size on interaction probability, fitting a binomial (link=logit) distribution. Insect species was included as a random factor in the model (R ² _adj = 0.15, N = 1040)
