摘要

我们考虑了一个两个物种的竞争模型，在该模型中，除了运动策略外，两个种群都是相同的：一个物种沿着适应度梯度向上移动，而另一个物种不扩散。虽然两个物种都可以在均匀的环境中共存，但我们表明，在某些测量中，有定向运动的物种比不扩散的物种有一些优势。相比之下，如果一个物种通过随机扩散移动，而另一个物种不扩散，那么非扩散种群可能具有优势。理解这些ODE-PDE混合系统的全部动力学提出了具有挑战性的数学问题。AMS受试者分类：35K57、35Q92、92D25

Advantage and Disadvantage of Dispersal in Two-Species Competition Models

We consider a two-species competition model in which both populations are identical except their movement strategies: One species moves upward along the fitness gradient, while the other does not diffuse. While both species can coexist in homogeneous environment, we show that the species with directed movement has some advantage over the non-diffusing species in certain measurement. In contrast, if one species moves by random dispersal while the other does not diffuse, then the non-diffusing population could have advantage. Understanding the full dynamics of these ODE-PDE hybrid systems poses challenging mathematical questions. AMS subject classifications: 35K57, 35Q92, 92D25

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.
