Abstract:
Dispersal is one of the critical process during the spreading stage of biological invasions. In particular, long distance dispersal events may increase dispersal ability of invasive species and thus accelerate the spread of the biological invasion. These events might also have huge consequences on the genetic diversity of the species. During my talk, I will present non-local equations model which can take into account long distance dispersal events. I will first focus on the propagation properties of the solutions of these nonlocal equations. I will show that the tail of the dispersal kernel play a critical role in the spreading speed of the invasion. Then, I will present some results on the inside dynamics of these solutions.
