Ocurrence of dry forest endemic amphibians in the Neotropic
The data includes georeferenced records of 39 endemic amphibian species to seasonally dry tropical forests (N-SDTF), using WGS 1984 decimal geographic coordinates (longitude and latitude). To obtain occurrence records, we conducted a comprehensive search was conducted using online databases (GBIF) and field data. We considered the taxonomic synonymy of the species and standardized the names according to the system proposed by Frost (1999) 2023 to ensure accuracy.
Steps to reproduce
The data curation process followed the methodology proposed by Hijmans and Ellith (2013), which involved four key steps. First, data with typographical errors in the coordinates or values that indicate no data were eliminated. Secondly, duplicate records were removed. Thirdly, records whose coordinates did not correspond to the registered country were eliminated. Finally, a single record was selected per pixel of 30 seconds of arc (~1 km) to reduce sampling bias. Data curation was carried out using the R package Dismo (Hijmans et al., 2017). Finally, we retained those species with at least 14 occurrence records which would allow us to model the distribution
