How Simple Sensing and Movement Rules Generate Diverse and Stable Predator–Prey Behaviors (IMAGE)
Caption
Researchers used computational simulations to demonstrate how simple sensing and movement rules—such as detection of distance and speed changes—constrain predator–prey interactions.
In a simplified model, detection alone (without directional information) triggers movement responses, producing chasing, ambush, escape, or freezing behaviors. Varying sensory ranges and movement rules lead to predictable, stable attack and defense strategies consistent with Nash equilibrium, while also allowing flexible behavioral switching and sensory advantages to emerge naturally.
