摘要

本文提出了具有排他性替代资源的非对称种群捕食系统的数学模型。特别地，本文分析了排他性替代资源对系统中IG捕食者和IG被捕食者消耗/捕食行为的影响。本文的研究结果表明，如果IG捕食者在消耗共享资源方面的竞争力和转换效率低于IG捕食者，则IG捕食者为确保其在系统中生存和共存而应维持的捕食率参数值存在一个下界。

Modeling and bifurcation analysis of an intraguild predation system

This paper proposes a mathematical model of an asymmetric intraguild (IG) predation system with an exclusive alternative resource. In particular, this paper analyzes the effects that the exclusive alternative resource has on the consumption/predation behaviors of both the IG predator and IG prey species in the system. The results presented on this paper show that, if the IG predator is less competitive in consumption and less efficient in conversion of the shared resource than that of the IG prey, then there exists a lower bound on the value of the predation rate parameter that should be maintained by IG predator species to ensure its survival and co-existence in the system.
