In Proceedings of the ITI 2012 34th International Conference on Information Technology Interfaces (ITI), Book Series: ITI. IEEE, 2012. ISSN: 1330-1012. Pp. 319-324978-953-7138-24-01330-1012http://hdl.handle.net/10400.21/5133A 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.engBeta(p, 2) densitiesAllee effectSymbolic dynamicsTopological entropyconference object10.2498/iti.2012.0438
