Results of network-based diffusion analysis (NBDA).

The difference between the fit of the nonsocial model and the fit for the social model is denoted by the change in AIC (ΔAIC). Therefore, positive values indicate a better fit for the social model (p values indicate significance). The social transmission estimate reflects the degree to which social interactions between bees influence the diffusion of string pulling. Positive social transmission estimates that do not cross zero (intervals) indicate significant influence of social interactions.
