Abstract

Understanding the effect of dispersal on fragmented populations has drawn the attention of ecologists and managers in recent years, and great efforts have been made to understand the impact of dispersal on the total population size. All previous numerical and theoretical findings determined that the possible response scenarios of the overall population size to increasing dispersal are monotonic or hump-shaped, which has become a common assumption in ecology. Against this, we show in this paper that many other response scenarios are possible by using a simple two-patch discrete-time model. This fact evidences the interplay of local dynamics and dispersal and has significant consequences from a management perspective that will be discussed.

对双斑块种群模型中扩散和局部动态综合效应的新认识

近年来，了解扩散对破碎化种群的影响引起了生态学家和管理者的关注，人们为了解扩散对总种群数量的影响做出了巨大努力。以往所有的数值和理论研究结果都认为，总种群数量对扩散增加的可能响应情况是单调的或驼峰形的，这已成为生态学中的一个常见假设。与此相反，我们在本文中利用一个简单的双斑离散时间模型证明了许多其他的反应情况。这一事实证明了局部动力学与扩散的相互作用，并将从管理角度对其产生重大影响进行讨论。

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.
