网络和群落生态学的一个主要探索集中在理解物种相互作用网络中结构模式的重要性——在给定地点和时间谁与谁相互作用的综合。在过去的几十年中，人们致力于通过特定结构承受对其结构或动力学的外部扰动的能力来推断其重要性。在这里，我们证明这种观点会导致不一致的结论。也就是说，网络结构的重要性随着在任何给定时间点作用于社区的外部扰动的函数而变化。因此，我们讨论了一个研究议程，以调查环境依赖框架下生态网络结构的相对重要性。我们假设，只有在环境依赖的框架下系统地研究网络结构和群落动态之间的联系，我们才能揭示群落容忍环境变化的极限。 “变化是唯一有意义的现实”斯蒂芬·J·古尔德。
A major quest in network and community ecology has been centered on understanding the importance of structural patterns in species interaction networks—the synthesis of who interacts with whom in a given location and time. In the past decades, much effort has been devoted to infer the importance of a particular structure by its capacity to tolerate an external perturbation on its structure or dynamics. Here we demonstrate that such a perspective leads to inconsistent conclusions. That is, the importance of a network structure changes as a function of the external perturbations acting on a community at any given point in time. Thus, we discuss a research agenda to investigate the relative importance of the structure of ecological networks under an environment-dependent framework. We hypothesize that only by studying systematically the link between network structure and community dynamics under an environment-dependent framework, we can uncover the limits at which communities can tolerate environmental changes. “Variation stands out as the only meaningful reality” Stephen J. Gould.
