"Spatial Heterogeneity and the Coexistence of Competing Species"

Abstract:
In this talk we use reaction-diffusion models to examine the impact of spatial heterogeneity on the coexistence of two competing species simultaneously inhabiting a bounded isolated habitat patch. Specifically, we are interested in the issue of when and how incorporating spatial variation in one or more coefficients in the model equations can lead to a prediction of coexistence in a model which fails to predict coexistence in the absence of the spatial variation. We employ elements of persistence theory, singular perturbation theory and eigenvalue analysis in our study.
