| Abstract: |
| In this talk, we investigate the impact of threshold harvesting rules on discrete-time population models with age structure. Specifically, we analyze how different thresholds for each age class influence the dynamics of the population. We discuss the existence of equilibria and their stability. We establish precise conditions for hydra effects and demonstrate that harvesting does not destabilize globally stable equilibria. In addition, our research yields insights into the emergence of unusual bifurcations, such as border-collision bifurcations. This is joint work with E. Liz (University of Vigo). |
