title: Data from: A global database of butterfly species native distributions

description: Butterflies represent a diverse group of insects, playing key ecosystem
 roles such as pollination and their larval form in herbivory. Despite
 their importance, comprehensive global distribution data for butterfly
 species is lacking. This lack of comprehensive global data has hindered
 many large-scale questions in ecology, evolutionary biology, and
 conservation at regional and global scales. Here, I use an integrative
 workflow that combines occurrence records, alpha hull polygons, species’
 dispersal capacity, natural habitat and environmental variables within a
 framework of species distribution models to generate species-level native
 distributions for butterflies at a global scale in contemporary period.
 The database releases native range maps for 10,372 extant species of
 butterflies at a spatial grain resolution of 5 arcmin (~10 km). This
 database has the potential to allow unprecedented large-scale analyses in
 ecology, biogeography, and conservation of butterflies. The maps are
 available in the WGS84 coordinate reference system (EPSG:4326 code) and
 stored as vector polygons in GEOPACKAGE format for maximum compression,
 allowing easy data manipulation using a standard computer. I additionally
 provide each species’ spatial raster. All maps and R scripts are open
 access and available for download at Dryad, and are guided by FAIR
 (Findable, Accessible, Interoperable, and Reusable) data principle. By
 making this data available to the scientific community, I aim to advance
 the sharing of biological data to stimulate more comprehensive research in
 ecology, biogeography, and conservation of butterflies.
description: # A global database of butterfly species native distributions **Data
 description within the folder "ButterflyMaps.zip":** All scripts
 and code necessary to repeat the analyses described here have been made
 available in the R package phyloregion This folder includes all the data
 for the Daru paper. The folder is structured as follows: \ButterflyMaps
 (contains all the input data files) \GreenMaps\CODES (contains all the R
 scripts that were generated and used in this project) The full folder
 structure is below: +---ButterflyMaps.zip \| +---Model_test_statistics.csv
 \| ---polygons \| ---rasters \| ---raw_rasters +---Data S1.zip \| ---Data
 S1.docx 1. ButterflyMaps.zip * Model_test_statistics.csv: a file with
 values of the three model test statistics quantifying the predictive
 accuracy of the models for each species: area under the curve (AUC), True
 Skill Statistic (TSS), and Boyce Index. Cells containing "NA"
 correspond to cells with missing data. * polygons: a folder with
 individual species polygons in geopackage format. Each species polygon has
 two fields: binomial, indicating the species binomial name, and origin
 corresponding to the native status of the species (1 for native species).
 The current dataset considered only native distributions. * rasters:
 folder with individual modeled spatial rasters in GeoTiff format at a
 grain resolution of 5–arc min (~10 km at the equator). * raw_rasters:
 folder with raster layers in GeoTiff format at a grain resolution of 5–arc
 min (~10 km at the equator) of the raw suitability scores to explore
 alternative approaches of thresholding the predictions. 2. Data_S1.zip\_ *
 Data S1.docx: A file in Word format with the ODMAP (Overview, Data, Model,
 Assessment and Prediction) protocol of reporting species distribution
 models. 3. phyloregion_1.0.9.tar.gz  R package used to run the analyses.
