Résumé: MB - Biological invasions: the role of adapation for heterogeneous environments -
Description: Gwenaël Peltier
When the environment is heterogeneous, the situation is much more complex. Depending on the profile of heterogeneities, the invasion may be either slowed or completely blocked. In some cases, the population adaption to the local environment is crucial for invasion to occur. We first consider a linear profile of heterogeneities, and then investigate the fully nonlinear case numerically as well as analytically (in a perturbative framework for the latter).
