Abstract: We study the role of age structure in determining the diffusive population dynamics. More precisely, by comparing principal eigenvalues between a diffusion operator with age structure and another one without age structure, we find that the former one is more complicated than the latter one and there even does not exist a definitive relation between them in the limiting sense with respect to the diffusion rate. Next we apply the above findings to a nonlinear diffusive age-structured equation and investigate the threshold dynamics and propagation dynamics respectively. The obtained results will explain how age structure effects the dynamics nontrivially.
