  We investigated the relationships between search efficiency, movement
strategy, and non-local communication in the biological context of animal
foraging. We considered situations where the members of a population of
foragers perform either Gaussian jumps or Levy flights, and show that the
search time is minimized when communication among individuals occurs at
intermediate ranges, independently of the type of movement. Additionally, while
Brownian strategies are more strongly influenced by the communication
mechanism, Levy flights still result in shorter overall search durations.
