Please interpret these results in the context of your study design and field conditions. The statistics above are based on spatial intersections with hexagonal grid cells and should complement — not replace — expert ecological judgment. check-Engine provided by World of Crayfish® (Ion et al. 2024).
WoC® Literature Coverage Analysis
This tool evaluates how well the baseline species is represented in the World of Crayfish® database relative to what is available in open scholarly and genomic repositories. It cross-references WoC® records against external sources to quantify indexing coverage. Note: many publications retrieved from these sources may not contain faunistic distribution data — low coverage percentages are expected and should not be interpreted as data gaps.

This is a preliminary contextual assessment. OpenAlex indexes scholarly works broadly — many results represent taxonomic, molecular, or ecological studies that may not include distributional records. GenBank sequences reflect genetic data deposits, not occurrence records. Coverage percentages indicate indexing overlap, not data completeness. check-Engine provided by World of Crayfish® (Ion et al. 2024).

Would you like to contribute your data?
Occurrence data are valuable for the broader scientific community. If you have been using this dataset as part of an ongoing publication, you can use our portal as a data repository — we will provide you with accession codes reserved for your dataset since submission. You can revisit and update publication details once your paper is published.
Remember: your data has not been saved — proceeding will submit it to WoC®.
FAIR-aligned data management. The World of Crayfish® platform follows FAIR principles (Findable, Accessible, Interoperable, Reusable) with a community-oriented data stratification model:
Level 0Open access — visible and downloadable by everyone. Typically used for non-indigenous (invasive) species records.Level 1Community access — visible and downloadable by registered users. Default for most indigenous species data.Level 2Restricted access — locations masked as hexagonal cells. Contact the data owner to request access.
Regardless of confidentiality level, all data contribute to aggregated spatial artefacts (hexagonal summaries) without revealing exact coordinates.
Data types accepted: unpublished field data, data under review (WoC® accession codes serve as repository identifiers), or records digitised from published literature. Before submitting, verify whether these records exist — use Search to check by DOI, citation, or species.
