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
