1954年，Hutchinson和Slobodkin提出，种群可以被视为反馈系统，它可以响应于环境波动，以大约一代人的时间频率共振。在本文中，我们通过构建几个基于控制人口年龄结构的人口方程的数学模型来追求这一观察结果。对于通过特定年龄的交互作用耦合的种群，研究了这种影响和其他几种生态重要性的影响的存在。
In 1954 Hutchinson and Slobodkin suggested that populations can be viewed as feedback systems that could resonate in response to environmental fluctuation with a frequency of approximately one generation time. In this paper we pursue this observation by constructing several mathematical models based on the demographic equations governing population age structure. The existence of this and several other effects of ecological importance are investigated for populations coupled by age—specific interactions.
