The difficulty in predicting responses to press perturbation is largely due to the tangled nature of indirect interactions in natural ecological networks. Although previous theories have paved the way for evaluating net interaction effects by incorporating direct and indirect effects related to press perturbation, there are still critical knowledge gaps regarding the relationships between net interaction effects and network topologies because of lack of comparable interaction strengths across ecosystems.

将网络交互效应与食物网中的网络拓扑联系起来

预测对压力扰动的反应的困难主要是由于自然生态网络中间接相互作用的复杂性。尽管先前的理论通过结合与新闻扰动相关的直接和间接影响来评估净交互效应铺平了道路，但由于缺乏跨生态系统的可比交互强度，在净交互效应和网络拓扑之间的关系方面仍然存在关键的知识差距。
