International audienceWe are interested in the dynamical behaviour of the solution set to a two component reaction–diusion system posed on non coincident spatial do- mains. The underlying biological problem is a predator–prey system featuring a non local numerical response to predation involving an integral kernel. Quite interesting while complex dynamics emerge from preliminary numerical simu- lations, driven both by diusivities and by the parametric form or shape of the integral kernel. We consider a simplied version of this problem, with constant coecients, and give some hints on the large time dynamics of solutions
