Resumen:
We study a simple model of a foraging animal that modifies the substrate on which it moves.This substrate provides its only resource, and the forager manages it by taking a limited portion at eachvisited site. The resource recovers its value after the visit following a relaxation law. We study differentscenarios to analyze the efficiency of the managing strategy, corresponding to control the bite size. Weobserve the non trivial emergence of a home range, that is visited in a periodic way. The duration of thecorresponding cycles and the transient until it emerges is affected by the bite size. Our results show thatthe most efficient use of the resource, measured as the balance between gathering and traveled distance,corresponds to foragers that take larger portions but without exhausting the resource. We also analyze theuse of space determining the number of attractors of the dynamics, and we observe that it depends on thebite size and the recovery time of the resource.
