The birth and death transition rates for a population are modelled as functions of both the population size and the environmental condition. An assortment of important theoretical results and techniques that can be utilized to analyze such a population's behaviour is covered. Consequently, these results and techniques are used to study two examples. Firstly, we study a population with a stable equilibrium state, whose per capita birth and death rates are linearly related to the environmental condition. (The environmental condition in turn is modelled as an Ornstein-Uhlenbeck process.) Secondly, we study a population affected by two interdependent environmental factors.
一个种群的出生和死亡转换率被建模为种群规模和环境条件的函数。涵盖了一系列可用于分析此类种群行为的重要理论结果和技术。因此，这些结果和技术被用于研究两个例子。首先，我们研究一个具有稳定平衡状态的种群，其人均出生率和死亡率与环境条件呈线性相关。（环境条件又被建模为一个奥恩斯坦 - 乌伦贝克过程。）其次，我们研究一个受两个相互依赖的环境因素影响的种群。
