Fig. 1 — Structure of the CESTES database. The database includes 80 Excel files for 80 datasets. Each dataset is composed of four matrices of data stored in spreadsheets: comm (species abundances [n = 68] or presences/absences [n = 12]), traits (species traits), envir (environmental variables), and coord (spatial coordinates). Each dataset also includes a DataKey (description of the entries of the Data tables), a Notes sheet (contact information for the dataset, and, when relevant, processing information), a Species list, and a Site list. The grey components can be the original data matrices, and additional information and do not appear in all the datasets, depending on specific needs (see Methods - Data processing section).
