The spatial distribution of foragers and food patches can influence antipredator vigilance

Abstract: Lay Summary In many animal species, individuals can join nearby feeding groups and can also allocate time to vigilance against predators. These 2 mechanisms can reduce the risk of predation, but they have rarely been considered together. In a model, I show that joining tendencies and vigilance levels can be influenced by the number of groups in the same area, by the spatial distribution of resources, and by predator attack tactics.
