Abstract:
In this article, we study a lattice differential model for a single
species with distributed age-structure in an infinite patchy environment.
Using method of approaches by Diekmann and Thieme, we develop a comparison
principle and construct a suitable sub-solution to the given model,
and show that there exists a spreading speed of the system which
in fact coincides with the minimal wave speed.
