Abstract

Flocking is a striking example of collective behaviour that is found in insect swarms, fish schools and mammal herds. A major factor in the evolution of flocking behaviour is thought to be predation, whereby larger and/or more cohesive groups dilute the effects of predators. In this work used global...

A major factor in the evolution of flocking behaviour is thought to be predation, whereby larger and/or more cohesive groups dilute the effects of predators. In this work used global positioning system (GPS) data to characterise the response of a group of prey animals (a flock of sheep) to an approaching predator (a herding dog).
