All of the factors listed can affect the size of primate groups. Nocturnal activity can reduce the amount of time that primates have to forage for food, which can lead to smaller group sizes. The amount and density of food can also affect group size, as primates will tend to form larger groups in areas where food is scarce. Competition over resources can also lead to smaller group sizes, as primates will tend to avoid areas where there is a lot of competition for food and other resources.
