摘要

本文建立了幼食饵、成年食饵和捕食者之间的捕食-食饵相互作用模型，考虑了食饵物种的阶段结构。功能响应被认为是比例相关的。据推测，成年猎物足够强壮，因此具有反捕食者的特征。利用几何方法讨论了共存平衡点的全局动力学问题。进一步证明了该系统对一些重要参数存在Hopf分岔。最后，通过数值模拟对理论结果进行了验证。

Dynamics of a stage structure prey-predator model with ratio-dependent functional response and anti-predator behavior of adult prey

In this paper, a predator-prey interaction model among juvenile prey, adult prey and predator has been developed where stage structure is considered on prey species. The functional responses has been considered as ratio dependent. It is assumed that that the adult prey is strong enough such that it has an anti-predator characteristic. Global dynamics of the co-existing equilibrium point has been discussed with the help of the geometric approach. Furthermore, it is established that the proposed system undergoes through a Hopf bifurcation with respect to some important parameters. Finally, some numerical simulations have been done to test our theoretical results.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
