Oscillatory Patterns from Social Foraging


Pattern formations in predator-prey
systems have been widely studied in the past. In contrast to existing studies
where growth and predation functional forms are analyzed, I will discuss the
effect of social interactions during foraging. Motivated by chemotaxis
equations, such as the Keller-Segel system, our model includes taxis terms where
foragers are attracted to prey. I will show that simple taxis of foragers and
randomly moving prey will not lead to any spatiotemporal pattern. However, a
population of foragers with two types of behaviours can lead to spontaneous
emergence of oscillatory patches. I will also discuss the conditions under which
one or another of these behavior is more beneficial to the individual by
measuring the food intake.
