Abstract

This paper considers a biological model in which two stages of the population, adults and preadults, are modeled by a Beverton-Holt type function and a logistic-type function. Two new models are proposed, each with an additional parameter representing the compensation. This new parameter is introduced in adult and juvenile populations. As a result, the Allee effect is observed in both models. The scenario of almost sure extinction can appear when the dynamic is chaotic enough.

论具有阿利效应和几乎肯定灭绝的线性-双曲线种群模型的动态变化
本文研究了一个生物模型,在该模型中,种群的两个阶段--成虫和幼虫--分别由一个贝弗顿-霍尔特型函数和一个逻辑型函数来模拟。本文提出了两个新模型,每个模型都有一个代表补偿的附加参数。在成体和幼体种群中引入了这一新参数。结果,在这两个模型中都观察到了阿利效应。当动态足够混乱时,几乎肯定会出现灭绝的情况。

期刊介绍: Applied Mathematics and Computation addresses work at the interface between applied mathematics, numerical computation, and applications of systems – oriented ideas to the physical, biological, social, and behavioral sciences, and emphasizes papers of a computational nature focusing on new algorithms, their analysis and numerical results. In addition to presenting research papers, Applied Mathematics and Computation publishes review articles and single–topics issues.
