Description

Invasive species pose major challenges for biodiversity and ecosystem management. In this talk, I present mathematical models to understand how biological invasions emerge, spread, and can be controlled. I first focus on early invasion stages, where stochastic effects are important, and discuss extinction probabilities and invasion thresholds. I then address invasion dynamics at larger spatial and temporal scales, with an application to the invasion of black cherry (Prunus serotina) in France, using an age-structured and spatially explicit model. I conclude with perspectives on spatial control strategies and coordinated management.
