Density-independent and density-dependent, stochastic and deterministic, discrete-time, structured models are formulated, analysed and numerically simulated. A special case of the deterministic, density-independent, structured model is the well-known Leslie age-structured model. The stochastic, dens

To describe the dynamics of a resource-dependent age structured population, a general non-linear Leslie type model is derived. The dependence on the resources is introduced through the death rates of the reproductive age classes. The conditions assumed in the derivation of the model are regularity a

The instabilities of the equilibria of a class of time discrete population growth models are studied. The models describe the growth of one species with age structure, where the survival probabilities are assumed to depend on the total population. Instability occurs when the fecundities or the survi

A simple population model is presented that exhibits both the period-doubling and the quasi-periodic routes to chaos with the variation of a single parameter. This fact is exploited to contrast the relative robustness of the two routes against structural perturbations in the form of added immigratio
