我们对生态系统的统计特性进行了分析研究,该生态系统由通过赫布规则给出的成对相互作用耦合并具有确定性自相互作用的物种组成。在模型中,每个物种都由一组无限的 p= αN 特征来表征。作为我们的主要结果之一,我们观察到,随着物种复杂性(性状数量)的增加,生态系统的合作性变得越来越差。
We do an analytical study of the statistical properties of an ecosystem composed of species that are coupledviapairwise interactions that are given by the Hebb rule and have deterministic self-interactionsu. In the model each species is characterized by an infinite set ofp= αNtraits. As one of our main results, we observe that the ecosystem becomes less cooperative as the complexity of species (number of traits) is increased.
