Abstract

This project aims to incorporate evolutionary processes that occur throughout invasions into range expansion theory, especially spatial sorting and gene-surfing. Spatial sorting consists of the fact that some individuals may present higher dispersal capacity then others, colonizing some regions of the invaded landscape before its co-specifics do. Gene surfing can be explained as mutations having a higher fixation probability, simply by being at the front of an invasion, when compared to well-mixed populations. The main focus is on the development of integro-difference equations models to study such phenomena. Most of the expected results are to come from analytical techniques and approximations with support from numerical methods. (AU)
