Gardner和Ashby（1970）的计算机研究表明，大型随机连接系统的稳定概率随着连接数量的增加而降低。这些结论并不适用于某些看似合理的食物网模型。如果食物网的特点是低同化效率，偏向于强自我调节的高营养级物种，或偏向于捐助者的依赖性，稳定的概率可以增加连接。
Computer studies by Gardner and Ashby (1970) show that large randomly connected systems have a decreasing probability of being stable as the number of connections increases. These conclusions are not appropriate to some plausible food web models. If the food web is characterized by low assimilation efficiencies, a bias toward strong self-regulation of higher trophic level species, or a bias toward donor dependence, the probability of stability can increase with increasing connectance.
