Geographical distribution of the observations of Eupulmonata on iNaturalist in Brazil.
Eupulmonata is used as an example since it’s the gastropod taxon with the largest number of observations. In general, observations are mostly concentrated around large metropolitan areas. The map was created with QGIS software (https://QGIS.org) using map data from Natural Earth (https://naturalearthdata.com) and observation coordinates from iNaturalist.
