We hypothesise that foraging group size (FGS) and population group size (PGS) in primates and carnivores are related to quantifiable variables indexing the intensity of exploitative competition. Group size is predicted to increase with both food density and travel capabilities, as estimated by the “constraint-free day-range” (DRs), i.e. the day-range of a solitary individual uninfluenced by competition from conspecifics. We test this “exploitation competition” hypothesis among primates and… CONTINUE READING
