GeX: an automated tool for generating XYD files for analysis of endemicity using VNDM

In the last decade, a method widely used to delimit areas of endemism is the analysis of endemicity (AE), a non‐hierarchical and grid‐dependent algorithm implemented through the package NDM/VNDM. Its input files are based on lists of georeferenced taxa, and any mistakes in their preparation will influence the results of the analyses. We describe here a free online automated tool for generating the input files for VNDM from simple spreadsheets.
