Data from: Geopolitical impacts on the description of new terrestrial mollusc species

Description This repository provides the raw data and codebase for analyzing scientific colonialism in the global discovery of mollusk species from 2003 to 2022. The code fully reproduces all analyses reported in the manuscript, including the classification of species descriptions by research collaboration type (domestic, mixed, or parachute research), extraction of socioeconomic variables from global datasets, statistical comparisons of taxonomic practices across geopolitical regions, and generation of all figures for the main text and supplementary materials. The workflow ensures transparent and replicable results, from data processing to visualization. File content RawData.xlsx: it represents the raw data on mollusc species descriptions published between 2003 and 2022. It contains 24 fields informing taxonomic ranks, authors' affiliation country, geographical coordinates of species type-locality, and details on methods and resources applied to each species description. R-code: script to reproduce all analyses and figures. Shapefiles.zip: it represents the "Shapefiles" folder directory, which includes four shapefiles in this zip. (i) landcover_SIMP, boundaries of land areas worldwide. (ii) world_limit, bounding box of world extent. (iii) world-administrative-boundaries, country-level geopolitical boundaries (see https://data.ipu.org/content/regional-groupings). (iv) wwf_realms, the biogeographical realm limits extracted from https://ecoregions.appspot.com/). Citation Abreu, E.C.T., Silva, E.L. & Moura, M.R. (2025).
