Abstract

This paper examines the stability of the Rosenzweig–MacArthur model distributed to identical discrete habitat patches. Migration between patches is assumed to follow the non-diffusive rule that individuals have a fixed rate of leaving their local habitat patch and migrating to another. Under this non-diffusive migration rule, we found that population dispersal on a non-regular and connected habitat network can both stabilize and destabilize the Rosenzweig–MacArthur model. It is also shown that our non-diffusive migration rule apparently becomes diffusive if the habitat network is regular.

非正则网络上具有非扩散扩散扩散的Rosenzweig–MacArthur模型的稳定性

本文研究了Rosenzweig–MacArthur模型分布在相同离散生境斑块上的稳定性。斑块之间的迁移被认为遵循非扩散规则，即个体离开当地栖息地斑块并迁移到另一个栖息地斑块的速率是固定的。在这种非扩散迁移规则下，我们发现种群在非规则和连通的栖息地网络上的扩散既可以稳定Rosenzweig–MacArthur模型，也可以破坏其稳定。研究还表明，如果栖息地网络是规则的，我们的非扩散迁移规则显然会变得具有扩散性。

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.
