Abstract

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 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 Contained

The data contained trophic interactions between resources (prey) and consumers (predators).

Spatial Location and Grain

The mainland of South Korea and Jeju Island.

Time Period and Grain

2008–2021.

Major Taxa

Microalgae (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 Measurement

Minimum taxonomic resolution was at the genus level for fish and benthic macroinvertebrates and order level for zooplankton and microalgae.

Software Format

Excel (*.xlsx).

KF-元网：韩国淡水生态系统营养元网

元网是为特定地区开发的节点及其潜在相互作用的字典，侧重于特定类型的生态系统。根据不同时空尺度的地方生物多样性信息，区域元网可以很容易地分解成地方网。生成的地方网有助于了解特定区域生态相互作用的时空变化。本研究尝试为韩国淡水生态系统开发了一个营养元网，称为 KF-元网。该元网包含从 730 项研究中收集的 446 个分类群之间的 23,074 种相互作用。该元网可用于了解不同地方食物网的时空变异性以及环境对食物网特性的影响。此外，这是首个为亚洲生态系统开发的元网，其中包含许多现有数据库无法提供的相互作用信息。此外，这项元网研究还丰富了我们对全球生态相互作用的了解。

期刊介绍： Global Ecology and Biogeography (GEB) welcomes papers that investigate broad-scale (in space, time and/or taxonomy), general patterns in the organization of ecological systems and assemblages, and the processes that underlie them. In particular, GEB welcomes studies that use macroecological methods, comparative analyses, meta-analyses, reviews, spatial analyses and modelling to arrive at general, conceptual conclusions. Studies in GEB need not be global in spatial extent, but the conclusions and implications of the study must be relevant to ecologists and biogeographers globally, rather than being limited to local areas, or specific taxa. Similarly, GEB is not limited to spatial studies; we are equally interested in the general patterns of nature through time, among taxa (e.g., body sizes, dispersal abilities), through the course of evolution, etc. Further, GEB welcomes papers that investigate general impacts of human activities on ecological systems in accordance with the above criteria.
