Abstract.In this paper, we study a two stream species Lotka–Volterra competition patch model with the patches aligned along a line. The two species are supposed to be identical except for the diffusion rates. For each species, the diffusion rates between patches are the same, while the drift rates vary. Our results show that the convexity of the drift rates has a significant impact on the competition outcomes: if the drift rates are convex, then the species with the larger diffusion rate wins the competition; if the drift rates are concave, then the species with the smaller diffusion rate wins the competition.

漂移速率不同的平流斑块环境中的扩散演化

SIAM 应用动力系统期刊》第 23 卷第 1 期第 696-720 页，2024 年 3 月。摘要.在本文中，我们研究了一个双流物种 Lotka-Volterra 竞争斑块模型，该模型中的斑块沿一条线排列。除了扩散率之外，这两个物种应该是相同的。对于每个物种，斑块间的扩散率相同，而漂移率不同。我们的结果表明，漂移率的凸性对竞争结果有显著影响：如果漂移率是凸性的，则扩散率较大的物种在竞争中获胜；如果漂移率是凹性的，则扩散率较小的物种在竞争中获胜。

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.
