Lourenço da Silva, Edson Data from Costa et al[Macroecological invisibility in apple snails (Gastropoda: Ampullariidae): uneven occurrence and molecular coverage across public repositories] Mendeley Data This dataset supports the manuscript “Macroecological invisibility in apple snails (Gastropoda: Ampullariidae): uneven occurrence and molecular coverage across public repositories”. The study evaluates how publicly available occurrence and molecular data represent the accepted recent diversity of Ampullariidae and how data gaps constrain macroecological inference. The dataset includes cleaned and taxonomically standardised occurrence records, a MolluscaBase-derived accepted-species reference list, GenBank and BOLD molecular records, repository/spatial-usability summaries, threshold-based visibility summaries, and sampling-completeness outputs across multiple spatial grains. The occurrence data distinguish scientific collections from observation-based records and classify records according to native, invasive or exotic distribution status. Spatial analyses are restricted to native-range scientific-collection records to avoid conflating native diversity patterns with introduced or invasive distributions. The data show that, although public repositories contain a substantial number of Ampullariidae records, coverage is highly uneven across taxa, regions and data types. The public occurrence dataset comprises 13,349 spatially unique records representing 119 accepted species, but only 3,614 native-range scientific-collection records representing 113 species were retained for the main spatial analyses. Repository presence and spatial usability are treated separately: some species are present in GBIF but lack directly usable coordinates, whereas others are not detected in the reprocessed GBIF species-level records. Literature-derived locality evidence is provided separately and was not incorporated into the spatial analyses. The molecular data also show uneven public representation. BOLD and GenBank together provide molecular records for 58 accepted species, leaving 113 species without public molecular data. The dataset should therefore be interpreted as a measure of public molecular coverage and molecular breadth, not as an estimate of true genetic diversity. BOLD BIN information is included as repository-provided barcode clustering information and should not be interpreted as formal species delimitation. Overall, the data show that Ampullariidae species become rapidly excluded from broad-scale inference as minimum occurrence thresholds increase, and that sampling completeness remains low and spatially uneven, especially in the main tropical centres of native diversity. These outputs can be used to reproduce the manuscript analyses, evaluate repository presence versus spatial usability, inspect threshold-based macroecological visibility, assess public molecular coverage, and identify priority regions and taxa for future sampling, digitisation and molecular work.
