Abstract

A general way to compute stochastic transport in a population dynamics model was presented. A Galerkin projection of the Frobenius-Perron operator was used in this technique describing the mass flow from cell to cell. The mass flux across basin boundaries, the probability density function and the Lyapunov exponents using spatial information were determined. Information combined with the topology of the system predicted the stochastic bifurcation to new dynamics, pointing the changes caused by the addition of noise.
