摘要
Discrete-time dynamics, mainly arising in boreal and temperate ecosystems for 物種 with non-overlapping generations, have been largely studied to understand the dynamical outcomes due to changes in relevant ecological parameters. The local and global dynamical behaviour of many of these models is difficult to investigate analytically in the parameter space and, typically, numerical approaches are employed when the dimension of the phase space is large. In this article we provide topological and dynamical results for a map modelling a discrete-time, three-物種 food chain with two 捕食者 物種 interacting on the same 獵物. The domain where dynamics live is characterised, as well as the so-called escaping regions, which involve 物種 extinctions. We also provide a full description of the local stability of
