两性群体的性状进化

Trait evolution in two-sex populations

Paweł Zwoleński

摘要:

提出了一个基于个体的两性群体表型性状进化模型,该模型包括异性个体的半随机交配、自然死亡和种内竞争。通过将个体数传递到无穷大,我们得到了描述雄性和雌性亚群中性状分布演化的宏观非线性微分方程系统。我们研究的解决方案,持久性或灭绝的标准,状态定理的渐近稳定性,我们稍后将适用于特定的例子性状遗传。

英文摘要:

We present an individual-based model of phenotypic trait evolution in two-sex populations, which includes semi-random mating of individuals of the opposite sex, natural death and intra-specific competition. By passing the number of individuals to infinity, we derive the macroscopic system of nonlinear differential equations describing the evolution of trait distributions in male and female subpopulations. We study solutions, give criteria for persistence or extinction, and state theorem on asymptotic stability, which we apply later to particular examples of trait inheritance.
