Title:Random Walks, Circuits, and Spatial Statistical Models for Gene Flow in Heterogeneous Landscapes
Seminar:Mathematical Biology and Physiology Seminar
Speaker:Ephraim Hanks, Penn State University
Abstract:
Abstract: Genetic data collected over space are commonly used to study how landscape features such as mountains, rivers, and roads affect connectivity in animal species. One approach correlates observed genetic distance with the circuit-theoretic resistance distance of a graph representation of the landscape. We examine links between this circuit modeling approach and random walk models for gene flow in heterogeneous environments. We show that a Gaussian Markov random field model can be constructed which matches the spatial structure implied by circuits and by the equilibrium state of a random walk model. This provides a spatial statistical model with links to a spatio-temporal data generating process.
