摘要

对于双斑块logistic模型，我们研究了分散强度和分散不对称性对种群总体丰度及其分布的影响。给出了两种完整的模型参数空间分类:一种是关于扩散导致总生物量比没有扩散时更小或更大，另一种是关于总生物量如何随扩散强度和扩散不对称性而变化。每个斑块的种群丰度对扩散强度和扩散不对称性的依赖关系也得到了充分的表征。此外，对于具有任意数量斑块的logistic模型，确定了分散引起的最大和最小种群大小，并建立了局部种群丰度与非分散之间的弱序保持结果。

Total biomass of a single population in two-patch environments

For the two-patch logistic model, we study the effect of dispersal intensity and dispersal asymmetry on the total population abundance and its distribution. Two complete classifications of the model parameter space are given: one concerning when dispersal causes smaller or larger total biomass than no dispersal, and the other addressing how the total biomass changes with dispersal intensity and dispersal asymmetry. The dependencies of the population abundance of each individual patch on dispersal intensity and dispersal asymmetry are also fully characterized. In addition, the maximal and minimal total population sizes induced by dispersal are determined for the logistic model with an arbitrary number of patches, and a weak order-preserving result correlated the local population abundances with and without dispersal is established.

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.
