RESUMO

The study of population dynamics becomes even more important nowadays because of its applications in a wide range of subjects, such as evolutive biology, ecology, economics and computational sciences, among many others. The use of networks, as well as cellular automata, to simulate populational dynamics is an ordinary tool because of its simplicity in the treatement of very complicated problems. In this work we use cellular automata to simulate populational dynamics where non equilibrium phase transitions in replicator models in one and two dimensions are analyzed and characterized by their universality classes. We also use cellular automata to study the possible origins of prime number cycling present in northern american Magicicada, showing that it is possible to generate prime number year life cycles whithout any predation effects.
