Biodiversity research typically focuses on species richness and has often neglected interactions, either by assuming that such interactions are homogeneously distributed or by addressing only the interactions between a pair of species or a few species at a time. In contrast, a network approach provides a powerful representation of the ecological interactions among species and highlights their global interdependence. Understanding how the responses of pairwise interactions scale to entire assemblages remains one of the great challenges that must be met as society faces global ecosystem change.
生物多样性研究通常侧重于物种丰富度，并且常常忽视物种间的相互作用，要么是假定这些相互作用是均匀分布的，要么是一次仅研究一对物种或少数几个物种之间的相互作用。相比之下，网络方法能够有力地呈现物种间的生态相互作用，并突显它们的全球相互依存关系。理解成对相互作用的响应如何扩展到整个群落，仍然是社会面临全球生态系统变化时必须应对的重大挑战之一。
