<i>Rheomergy</i> : collective behaviour mediated by active flow-based recruitment

The physics of signal propagation in a collection organisms that communicate with each other both enables and limits how active excitations at the individual level reach, recruit lead to collective patterning. Inspired by patterns planar swarm bees release pheromones, use fanning flows additional bees, we develop theoretical framework for patterning via flow-based recruitment. Our model generalizes well-known Patlak-Keller-Segel diffusion-dominated aggregation leads more complex phase space spanned two dimensionless parameters measure scaled stimulus/activity chemotactic response. Together these determine efficacy communication variety migration consistent observations.
