(a) Summary of linear model representing the trip duration according to the type of resources collected by mixed foragers. Trip duration was natural-log transformed to obtain a Gaussian distribution. Significant effects are in bold. Model selection shown in Table S2A. (b) Summary of linear model representing the mass on departure according to the trip duration for mixed foragers. Trip duration has been natural log transformed to obtain a Gaussian distribution. Significant effects are in bold. Model selection shown in Table S2B.
