KF-metaweb: A trophic metaweb of freshwater ecosystems of South Korea (Version 1.0)

Motivation: 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 23074 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.

This dataset contains two files. One is the dataset and another is R code to reproduce the result. The dataset contains trophic interactions about different organisms found in freshwater ecosystems of South Korea which includes: Microalgae (belongs to the phylum Cyanobacteria, Bygra, Cryophyta, Myozoa, Ochrophyta, Charophyta, Chlorophyta, Euglenozoa and Mycetozoa), Zooplanktons (belongs to the phylum Arthropoda and Rotifera), Benthic macroinvertebrates (represented by the phylum Platyhelmenthes, Annelida, Arthropoda and Mollusca) and Fishes.

## Description of the data and file structure

The database (KF-metaweb) is available in the latest Excel Workbook (*.xlsx) format and includes four sheets: ‘Metaweb,’ ‘Node taxonomy,’ ‘Reference’ and ‘Trophic level.’ The first sheet contains the interactions among different node...
