MotivationThe 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.Main Types of Variables ContainedThe data contained trophic interactions between resources (prey) and consumers (predators).Spatial Location and GrainThe mainland of South Korea and Jeju Island.Time Period and Grain2008–2021.Major TaxaMicroalgae (belonging to the phyla Cyanobacteria, Bygra, Cryophyta, Myozoa, Ochrophyta, Charophyta, Chlorophyta, Euglenozoa and Mycetozoa), zooplankton (belonging to the phyla Arthropoda and Rotifera), benthic macroinvertebrates (Platyhelmenthes, Annelida, Arthropoda and Mollusca) and fish.Level of MeasurementMinimum taxonomic resolution was at the genus level for fish and benthic macroinvertebrates and order level for zooplankton and microalgae.Software FormatExcel (*.xlsx).

KF-metaweb：韩国淡水生态系统的营养元网络

动机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 个分类群之间的 23,074 种相互作用。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。包含的变量的主要类型数据包含资源（猎物）和消费者（捕食者）之间的营养相互作用。空间位置和谷物韩国大陆和济州岛。时间周期和谷物2008 –2021.主要分类微藻类（属于蓝细菌门、Bygra门、冰藻门、Myozoa、Ochrophyta、轮藻门、绿藻门、眼虫门和霉菌门）、浮游动物（属于节肢动物门和轮虫门）、底栖大型无脊椎动物（扁形动物门、环节动物门、节肢动物门和软体动物门）加州）和鱼类。测量水平鱼类和底栖大型无脊椎动物的最小分类分辨率为属水平，浮游动物和微藻的最低分类分辨率为目水平。软件格式Excel (*.xlsx)。
