                         tools to predict areas with potential for occurrence of native, 
                         invasive and endangered species, based on current and future 
                         environmenal and climate conditions. Despite their global use, 
                         evaluating the accuracy of SDMs based only on presence records is 
                         still a challenge. The performance of models depends on the sample 
                         size and species prevalence. Recently, studies to model the 
                         distribution of species in the Caatinga biome in Northeast Brazil 
                         have gained force, raising the question about the minimum number 
                         of presence records adjusted to different prevalences that are 
                         necessary to generate accurate SDMs. In this context, the 
                         objective of this study was to indicate minimum numbers of 
                         presence records for species with different prevalences in the 
                         Caatinga biome to obtain accurate SDMs. For that purpose, we used 
                         a method involving simulated species and performed repeated 
                         evaluations of the models performance in function of the sample 
                         size and prevalence. The results indicated that for this approach 
                         in the Caatinga biome, the minimum required numbers of specimen 
                         records were 17 and 30 for species with narrow and widespread 
                         distributions, respectively.",
