The metaweb is a dictionary of nodes and their potential interactions developed for a particular region, focusing on a particular type of ecosystem. Based on the local biodiversity information at different spatial and temporal scales, the regional metaweb can be easily decomposed into local webs. The generated local webs are useful for understanding spatiotemporal variations in ecological interactions in a particular region. In this study, an attempt was made to develop a trophic metaweb for freshwater ecosystems in South Korea, called the KF-metaweb. The metaweb contains 23,074 interactions between 446 taxa collected from 730 studies. This metaweb can be used to understand the spatiotemporal variability of different local food webs and the effects of the environment on food web properties. Furthermore, this is the first metaweb developed for any Asian ecosystem that contains information about many interactions that are unavailable in any other existing database. In addition, this metaweb study enriches our global understanding of ecological interactions.

KF-metaweb：韩国淡水生态系统的营养元网络


元网络是为特定区域开发的节点及其潜在交互的字典，重点关注特定类型的生态系统。基于不同时空尺度的局部生物多样性信息，区域元网络可以很容易地分解为局部网络。生成的局部网络有助于理解特定区域生态相互作用的时空变化。在这项研究中，尝试为韩国淡水生态系统开发一个营养元网络，称为 KF-元网络。该元网络包含从 730 项研究中收集的 446 个分类单元之间的 23,074 个相互作用。该元网络可用于了解不同当地食物网的时空变化以及环境对食物网特性的影响。此外，这是为任何亚洲生态系统开发的第一个元网络，其中包含任何其他现有数据库中不可用的许多交互信息。此外，这项元网络研究丰富了我们对生态相互作用的全球理解。
