In ecological models complexity often arises due to the presence of interactions complicating the trophic network. An example of this it is the case of kleptoparasitism: a herbivorous scavenger B competes with the predator W for carcasses of its prey D. B may also be preyed on by W, in its juvenile age, and it competes with D for vegetation. This scenario is inspired by the behavior of wild boar observed in the Northern Apennine, Italy, competing with wolves for carcasses of fallow deer. The dynamical system presented here is a version of a model already studied by the authors, simplified in order to single out the essence of kleptoparasitism as an interaction giving rise to complexity.

Abstract
In ecological models complexity often arises due to the presence of interactions complicating the trophic network. An example of this it is the case of kleptoparasitism: a herbivorous scavenger B competes with the predator W for carcasses of its prey D. B may also be preyed on by W, in its juvenile age, and it competes with D for vegetation. This scenario is inspired by the behavior of wild boar observed in the Northern Apennine, Italy, competing with wolves for carcasses of fallow deer. The dynamical system presented here is a version of a model already studied by the authors, simplified in order to single out the essence of kleptoparasitism as an interaction giving rise to complexity.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
