    Complex Behavior in a Discrete Coupled Logistic Model for the Symbiotic Interaction of Two Species by Ricardo López-Ruiz, Danièle Fournier-Prunaret

    Published 2004-06-01
    “…The coupling depends on the population sizeof both species and on a positive constant $\lambda$, called the mutual benefit.Different dynamical regimes are obtained when the mutual benefit is modified.For small $\lambda$, the species become extinct. For increasing $\lambda$,the system stabilizes in a synchronized state or oscillates in a two-periodic orbit.For the greatest permitted values of $\lambda$, the dynamics evolves into a quasiperiodic,into a chaotic scenario, or into extinction. …”
