From random times to fractional kinetics

In this paper we study the effect of the subordination by a general random time-change to the solution of a model on spatial eco- logy in terms of its evolution density. In particular on traveling waves for a non-local spatial logistic equation. We study the Cesaro limit of the subordinated dynamics in a number of particular cases related to the considered fractional derivative making use of the Karamata Tauberian theorem.
