Range dynamics for a spatially structured asexual population

By Gaël Raoul (CNRS) Abstract: Natural populations live in a heterogeneous environment and tend to adapt their pheno-types to their local environment. To understand the range dynamics of a population, we thus need to consider the spatial propagation of the population, but also its evolutionary dynamics. Starting from simple 1D linear environments, we will discuss how we can try to consider more complex situations: populations living in the 2D plane, and populations living in an environment that has a general heterogeneity at large scales. We will dis-cuss how we can take advantage of stochastic phenomena to derive a simple macroscopic description of a population range. ---------------------------------- Institut Henri Poincaré, 11 rue Pierre et Marie Curie, 75005 PARIS http://www.ihp.fr/
