Abstract

We consider a hybrid model of an annual species with the timing of a stage transition governed by density dependent phenology. We show that the model can produce a strong Allee effect as well as overcompensation. The density dependent probability distribution that describes how population emergence is spread over time plays an important role in determining population dynamics. Our extensive numerical simulations with a density dependent gamma distribution indicate very rich population dynamics, from stable/unstable equilibria, limit cycles, to chaos.

与密度相关的物候学带来的近邻效应。

我们考虑了一个一年生物种的混合模型，该模型的阶段转换时间受密度相关物候学的影响。我们发现，该模型会产生强烈的阿利效应和过度补偿。与密度相关的概率分布描述了种群出现在时间上的分布情况，它在决定种群动态方面起着重要作用。我们利用与密度相关的伽马分布进行了大量数值模拟，结果表明种群动态非常丰富，从稳定/不稳定平衡、极限循环到混乱。

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.
