Historicity of a Simple Competition Model

A Lotka–Volterra competition model was constructed to demonstrate historicity in community assemblage through competitive exclusion. Gilpin previously showed that if two five-species subcommunities have been self-organized through competitive exclusion, the resultant assemblage was dominated by either one of the subcommunities. I have extended his experiment and confirmed his results using two subcommunities consisting of three species as well as five species. Further experiments with two subcommunities of different sizes showed not only asymmetry but also a new feature that the smaller subcommunities tended to overcome the larger one.
