在这项工作中，我们研究了当选择对生殖、生存或两者都起作用时，人口结构对进化动力学的影响。与先前发现的中性突变体的固定概率随着群体变得年轻而下降的模式相反，我们证明了具有恒定选择优势的突变体在年轻个体比例居中的群体中可能具有最大或最小的固定概率。这凸显了生活史和人口结构在研究进化动力学中的重要性。我们还说明了在年龄结构存在的情况下，生殖选择和生存选择的根本区别。此外，我们还评估了种群大小和结构在决定突变的固定概率方面的相对重要性。我们的工作为在人口结构不可忽视的情况下也研究人口密度和频率依赖效应奠定了基础。
In this work, we study the effects of demographic structure on evolutionary dynamics when selection acts on reproduction, survival, or both. In contrast to the previously discovered pattern that the fixation probability of a neutral mutant decreases while the population becomes younger, we show that a mutant with a constant selective advantage may have a maximum or a minimum of the fixation probability in populations with an intermediate fraction of young individuals. This highlights the importance of life history and demographic structure in studying evolutionary dynamics. We also illustrate the fundamental differences between selection on reproduction and selection on survival when age structure is present. In addition, we evaluate the relative importance of size and structure of the population in determining the fixation probability of the mutant. Our work lays the foundation for also studying density- and frequency-dependent effects in populations when demographic structures cannot be neglected.
