报告内容简介:
In this talk, we will introduce some new results on the dynamics of an Intraguild predator(IGP) model with prey subject to strong Allee effects. We mainly consider the influences of the death rates of the IG prey and IG predator, and the influences of strong Allee effects on the dynamics of the model. It is shown that the IGP model exhibits one (extinction of all species), two (bi-stability) or three (tri-stability) global attractors. These results indicates that the IGP model with strong Allee effects has very rich dynamic behaviors.
