时变环境中的分子进化
Molecular Evolution in Time Dependent Environments
摘要:
研究了动态复制景观中的拟种理论。一个有意义的渐近拟物种被定义为周期时间依赖。准种的组成在振荡周期内不断变化。对于高振荡频率,误差阈值朝向时间平均景观的位置移动,并且对于低振荡频率,误差阈值紧密地跟随景观。
英文摘要:
The quasispecies theory is studied for dynamic replication landscapes. A meaningful asymptotic quasispecies is defined for periodic time dependencies. The quasispecies' composition is constantly changing over the oscillation period. The error threshold moves towards the position of the time averaged landscape for high oscillation frequencies and follows the landscape closely for low oscillation frequencies.
