Resumen:
We study the influence of altruistic behavior in a preypredator model permitting the preys to commit suicide by confronting the predators instead of escaping. Surprising, altruistic behavior at microscopic (local) scale, leads to the emergence of new complex macroscopic (global) phenomena characterized by dramatic changes in the dynamic topology of the preypredator spatiotemporal distribution, yielding spiral patterns. We show that such dynamics enhances the prey´s survivability.
