title: Legume and ant polygons for range size analysis and visualization

description: Mutualism improves organismal fitness, but strong dependence on another
 species can also limit a species’ ability to thrive in a new range if its
 partner is absent. We assembled a large, global dataset on mutualistic
 traits and species ranges to investigate how multiple plant-animal and
 plant-microbe mutualisms affect the spread of legumes and ants to novel
 ranges. We found that generalized mutualisms increase the likelihood that
 a species establishes and thrives beyond its native range, whereas
 specialized mutualisms either do not affect or reduce non-native spread.
 This pattern held in both legumes and ants, indicating that specificity
 between mutualistic partners is a key determinant of ecological success in
 a new habitat. Our global analysis shows that mutualism plays an
 important, if often overlooked, role in plant and insect invasions.

 These files are part of the data used in the manuscript "Generalized
 mutualisms promote range expansion in both plant and ant partners"
 published in September 2023 in the Proceedings of the Royal Society B.
 This dataset contains information on spatial polygons in which various ant
 species are found, and the polygons themselves in various formats. The
 data were assembled using the Global Ant Biodiversity Informatics (GABI)
 database as part of the Antmaps project by co-authors BG and EPE and their
 colleagues. For detailed information on how these data were collated,
 please see https://antmaps.org/about.html Access this dataset on Dryad:

 file structure File list: A) Bentity2\_shapefile\_fullres.dbf B)
 Bentity2\_shapefile\_fullres.prj C) Bentity2\_shapefile\_fullres.shp D)
 Bentity2\_shapefile\_fullres.shx E) GABI\_Data\_Release1.0\_18012020.csv
 The data consist of a CSV file containing the names of the spatial
 polygons in which each ant species was recorded in the GABI database. The
 names of the unique polygons are given in the "bentity2\_name"
 column in the CSV file. The other four files are the spatial polygons
 shapefiles in various formats. Only the .shp file was used in our analysis

 This file (GABI\_Data\_release1.0\_18012020.csv) reflects occurrence data
 for valid ant species and subspecies data compiled as part of the Global
 Ant Biodiversity Informatics (GABI) Project, as of January 18, 2020. Some
 data visualized on Antmaps.org have been excluded from this release,
 notably the Antweb data, because they should be retrieved directly from
 Antweb.org. We also have excluded records that couldn’t be assigned to a
 valid species, couldn’t be assigned to a bentity\_2 polygon, and those
 that we believe are outside the native ranges of the species. Methods: The
 methods for compiling the data are included in the following publication.

 we use to organize our data. * accession\_number: Additional codes that
 are inherited from or refer to the original data source. * citation: The
 source of the record. * genus\_name\_pub: The ant genus name included as
 reported in the original source. * species\_name\_pub: The ant species
 name as reported in the original source. * valid\_species\_name: The valid
 species name based on current taxonomy, determined by us to the best of
 our ability. * type\_of\_data: Refers to the basis of the record
 (Literature, Museum Specimen, Personal collection) * dubious: Indicates
 whether the record has been flagged as potentially invalid. These should
 be filtered out before analysis. * note\_dubious: A note for more info on
 why a record is considered dubious, if available. * locality: Text
 description of the locality. * country: The country. * adm1: The 1st level
 administrative area. * adm2: The 2nd level administrative area. *
 dec\_lat: The latitude in decimal degrees. * dec\_long: The longitude in
 decimal degrees. * bentity2\_name: Since many points do not have
 latitude-longitude point data, we assigned each record to a common system
 of 546 polygons for visualization and analysis. These mostly reflect
 political boundaries but can be on the country level (for small- and
 medium-sized countries) or adm1 levels (for larger countries). Some
 polygons reflect spatial units that are biogeographic in nature rather
 than political, for example island boundaries. The bentity2 polygons are
 included in the accompanying shapefile. * insert\_date: The date the
 record was added to our PostGRES database, although it may have been
 originally recorded by other sources earlier. * update\_date: The date the
 record was last changed. 5. Missing data codes: " " 6.
