Abstract Genetic information is crucial for species identification, population genetics structure, evolutionary relationships, and biodiversity monitoring. It helps address gaps related to Linnean (taxonomic uncertainty) Darwinian (phylogenetic knowledge) shortfalls. Understanding these can guide data collection reduce This study focuses on compiling genetic 748 fish in the Tocantins-Araguaia basin, examining number of unique genomic regions individual sampled per species. We also investigated factors that determine availability by linking it with macroecological predictors. Our findings reveal fewer than one-third endemic have resources available. The shortfall - lack phylogenetic knowledge a key factor limiting data, experiencing more this having less information. underscores need increased sampling better assess biological like structure.
