增长种群中Muller棘轮效应的分析结果
Analytical results on the Muller's ratchet effect in growing populations
摘要:
Fontanari等人介绍了[Phys. Rev. Lett. 91,218101(2003)]的一个模型,用于研究穆勒的棘轮现象在不断增长的无性种群。他们研究了两种情况,包括或不包括每个新生儿的死亡概率,但只能在无衰变的情况下找到解析(递归)表达式。在本文中,一个分支过程的形式主义是用来找到recorrence方程,除了确认有趣的效果,他们的模拟显示,推广的分析结果的原始文件。
英文摘要:
Fontanari et al introduced [Phys. Rev. Lett. 91, 218101 (2003)] a model for studying the Muller's ratchet phenomenon in growing asexual populations. They studied two situations, either including or not a death probability for each newborn, but were able to find analytical (recursive) expressions only in the no-decay case. In this paper a branching process formalism is used to find recorrence equations that generalize the analytical results of the original paper besides confirming the interesting effects their simulations revealed.
