Direction-Dependent Communication in an Individual-Based Model of Collective Behaviour


Flocks of birds, schools of fish, and insect swarms provide examples of animals exhibiting collective behaviour. Models of collective behaviour connect mechanisms and behavioural rules to group-level pattern formation. In this presentation, direction-dependent communication mechanisms are incorporated into a one-dimensional individual-based model (IBM) of collective behaviour. The IBM is formulated in terms of the three social interaction forces: repulsion, alignment, and attraction, and includes information regarding conspecifics’ direction of travel. The IBM produces a variety of complex spatial patterns and adding density-dependent movement speed to the IBM results in splitting and merging patterns. This suggests the importance of directional communication in collective behaviour.
