Abstract: | We carry out analytical and numerical analysis of a model of an ecological system described by a system of nonlinear partial differential equations of reaction-diffusion type. We find conditions for the bifurcation of periodic spatially homogeneous and inhomogeneous solutions from the thermodynamic branch of the system. We show that the passage to diffusion chaos in the model occurs, in complete agreement with the universal Feigenbaum-Sharkovskii-Magnitskii bifurcation theory, via a subharmonic cascade of bifurcations of stable limit cycles. |
