Modeling of Stochastic Evolutionary Dynamics

在这个项目中，研究了随机进化动力学和种群动力学的建模。特别是，利用基于个体的模型模拟宿主与寄生虫之间的共同进化相互作用，并广泛研究了二维连续空间中生灭过程的随机性影响。基于个人的建模的介绍已经开发出来，实现基于个人的模型的库现在通过PI的网页http://gi.ics.nara-wu.ac.jp/~takasuFour向公众开放，论文由这项资助发表。Stokke b.g.， F.

In this project, modeling of stochastic evolutionary dynamics together with population dynamics has been explored. Especially, co-evolutionary interactions between hosts and parasites were simulated using individual-based models and the effect of stochasticity of birth-death process in two-dimensional continuous space was extensively studied.Introduction to individual-based modeling was developed and the library to implement individual-based models in general is now open public through the PI's web page at http://gi.ics.nara-wu.ac.jp/~takasuFour papers are published supported by this grant.Stokke B.G., F.
