We study a simple model of a foraging animal that modifies the substrate onwhich it moves. This substrate provides its only resource, and the foragermanage it by taking a limited portion at each visited site. The resourcerecovers its value after the visit following a relaxation law. We studydifferent scenarios to analyze the efficiency of the managing strategy,corresponding to control the bite size. We observe the non trivial emergence ofa home range, that is visited in a periodic way. The duration of thecorresponding cycles and the transient until it emerges is affected by the bitesize. Our results show that the most efficient use of the resource, measured asthe balance between gathering and travelled distance, corresponds to foragersthat take larger portions but without exhausting the resource. We also analyzethe use of space determining the number of attractors of the dynamics, and weobserve that it depends on the bite size and the recovery time of the resource.
