  • Generalized models from Beta(p,2) densities with strong allee effect: dynamical approach
    Publication . Aleixo, Sandra; Rocha, J. Leonel
    A dynamical approach to study the behaviour of generalized populational growth models from Bets(p, 2) densities, with strong Allee effect, is presented. The dynamical analysis of the respective unimodal maps is performed using symbolic dynamics techniques. The complexity of the correspondent discrete dynamical systems is measured in terms of topological entropy. Different populational dynamics regimes are obtained when the intrinsic growth rates are modified: extinction, bistability, chaotic semistability and essential extinction.

  • Modeling Allee Effect from Beta(p, 2) Densities
    Publication . Rocha, J. Leonel; Aleixo, Sandra
    In this work we develop and investigate generalized populational growth models, adjusted from Beta(p, 2) densities, with Allee effect. The use of a positive parameter leads the presented generalization, which yields some more flexible models with variable extinction rates. An Allee limit is incorporated so that the models under study have strong Allee effect.
