METHODS Data Collation Data was collected from published studies or in-press studies that focused on human impacts toward soil biodiversity. Potential relevant studies must compare multiple sites which having different land use type and/or intensity. In addition, species abundance, richness, occurrence, or other diversity metrics must be present in the study, so that diversity can be estimated. Furthermore, the information of the sites location is also very important, studies which have the sites coordinates are more preferable. The coordinates are very useful not just to pinpoint the exact location on the map, but also to help us acquire other information, e.g. climate, biome, and ecoregion (all paper criteria similar to Newbold et al. 2015). To find these potential relevant studies, I used Web of Science ( and Google Scholar ( as the search engine with “soil invertebrate”, “land-use”, “pitfall trap”, and “ground invertebrate” as my search term. The corresponding authors of the suitable studies were contacted, asking whether they are willing to share their raw data (which were not usually made fully available in the paper or supplementary files). From the total of 24 authors contacted, five of them agreed to give me the raw data. After receiving the data, they were coded into a structured pdf form and excel spreadsheet. The pdf form captured the site- and species-specific information provided by the papers or
