The data included in this database are mainly derived from expert-based databases, published material and bat researchers, therefore ensuring the accuracy of the included data. We provided the corresponding reference (when applicable) for each cave record for cross-referencing and data validation purposes. When published “cave datasets” were unclear or lacked detailed information, we contacted the corresponding authors. We encourage continued contributions to the DarkCideS database as we aim to regularly update the entries for species checklists, traits, geographical locations of caves, and species occurrence data. For species ecological status (e.g., current conservation status, population trends, geopolitical endemism), we will update entries after every IUCN Red List assessment cycle. Datasets that were originally entered as “unpublished” or “personal data'' will also be updated after the respective author or contributor has published their findings. The database will be updated when new data are contributed and will be corrected when an error in the data entries are reported to any of the corresponding authors. Quality screening of new entries based on the criteria listed above will be made before adding new records to the database (Figure 5). Once an update is made, a release note will be published on the database website. When updating new versions of DarkCideS, we will continue to make available previous releases. Contributors will be included as co-authors when the next version of the database is published. Furthermore, as each cave has a unique ID, additional surveys of other taxa at the same locality can be integrated into the database, to provide a backbone for enhancing our understanding of cave biodiversity through time.
