In this talk, I will discuss the spreading properties of solutions of some diffusive prey-predator (or combustion) systems, for which the comparison principle does not hold. Both species are assumed to initially inhabit a compactly supported region. We will see that spreading then occurs, for both species, with a definite speed. Intriguingly, the spreading speeds may be different between the prey and the predator, depending on the situation. This is a joint work with A. Ducrot and H. Matano.
