A population model explicitly describing the dynamics of an arbitrary population size distribution is presented. One consequence of the model is an equation for the exact shape of the size distribution of a stationary or steady-state population. The shape is expressed as a function of sizespecific mortality and growth rates. From the equation, various mortality estimation formulas can be derived, two of which are discussed in detail. One of the methods permits estimation of size-specific mortality rates without the assumption of a theoretical growth model.
提出了一个明确描述任意种群规模分布动态的种群模型。该模型的一个结果是得到了一个关于静态或稳态种群规模分布精确形状的方程。其形状表示为特定规模死亡率和增长率的函数。从该方程可以推导出各种死亡率估计公式，其中两个将详细讨论。其中一种方法允许在不假设理论增长模型的情况下估计特定规模死亡率。
