Volterra incorporating a logisitic limitation of the P. F. Verhulst type on growth of the prey and a limitation of the G. F. Gause type on the intensity of predation of the predator on the prey and of the top-predator on the predator. This study highlights that this model has several Hopf bifurcations and a period-doubling cascade generating a snail shell-shaped chaotic attractor.<\/jats:p><jats:p>With the aim of facilitating the choice of the simplest and most consistent model a comparison is established between this model and the so-called Rosenzweig\u2013MacArthur and Hastings\u2013Powell models. Many resemblances and differences are highlighted and could be used by the modellers.<\/jats:p><jats:p>The exact values of the parameters of the Hopf bifurcation are provided for each model as well as the values of the parameters making it possible to carry out the transition from a typical phase portrait characterizing one model to another (Rosenzweig\u2013MacArthur to Hastings\u2013Powell and vice versa).<\/jats:p><jats:p>The equations of the Volterra\u2013Gause model cannot be derived from those of the other models, but this study shows similarities between the three models. In cases in which the top-predator has no effect on the predator and consequently on the prey, the models can be reduced to two dimensions. Under certain conditions, these models present slow\u2013fast dynamics and their attractors are lying on a slow manifold surface, the equation of which is given.<\/jats:p>","DOI":"10.1142\/s0218127405012934","type":"journal-article","created":{"date-parts":[[2005,7,7]],"date-time":"2005-07-07T13:48:02Z","timestamp":1120744082000},"page":"1689-1708","source":"Crossref","is-referenced-by-count":16,"title":["CHAOS IN A THREE-DIMENSIONAL VOLTERRA\u2013GAUSE MODEL OF PREDATOR\u2013PREY TYPE"],"prefix":"10.1142","volume":"15","author":[{"given":"JEAN-MARC","family":"GINOUX","sequence":"first","affiliation":[{"name":"PROTEE Laboratory, University of South Toulon Var, B.
