本单元的题目实际上是一本很有影响力的书的题目。玛雅在20世纪70年代写道，在这本书中，梅阐述了生态系统中的群落结构与其稳定性之间的关系。当时已经积累了大量的证据表明，在自然界中，结构复杂的群落往往比简单的群落更稳定。这些观察导致了一种几乎是教条式的观点，即稳定性是自然生态系统复杂性的结果。梅在1970年代挑战了这一观点，他用数学方法证明，在模型中，生态系统的稳定性随着群落中物种数量的增加而降低，因此不能被视为复杂性的直接结果。为了得到这个结果，May研究了
The title of this module is in fact the title of an influential book that Robert M. Maya wrote in the 1970’sb. In this book May addressed the relationship between community structure in ecosystems and their properties of stability. At the time considerable evidence had been accumulated to suggest that in nature structurally complex communities tend to be more stable towards perturbations than simple ones. These observations led to an almost dogmatic view that stability results from the complexity of natural ecosystems. May challenged this view in the 1970’sc by showing mathematically that in model ecosystems stability decreases with the number of species in a community and can therefore not be regarded as a straightforward consequence of complexity. To derive this result May investigated the stability properties of
