Factors: state (resident or disperser), t = time (day), and sex (male or female).
Covariates: sr = sex-ratio and d = density.
K = number of parameters.
Competing best models, having ΔAICc values lower than 2, are models 1 to 5 and the one including all significant effects is model 3 in bold (see Table 3 for LRT statistics associated). The 20 best models are shown.
