摘要：Biological invasions contribute significantly to the loss of global biodiversity. Despite the growing number of works on the subject, studies that address the distribution of these species are still needed. The objective of this study was to evaluate the dispersion of five invasive exotic species (Artocarpus heterophyllus, Crotalaria retusa, Leucaena leucocephala, Megathyrsus maximus and Prosopis juliflora) according to biome, climate, Federal Conservation Units and land use and occupation. For this, georeferenced occurrence points of the species were obtained from the specieslink and Gbif databases. These points were plotted on thematic maps made in the Qgis 3.18.3 software. The species M. maximus was the one with the highest number of records in Brazil (644), followed by C. retusa (446), L. leucocephala (426), A. heterophyllus (315) and P. juliflora (150). The biome with the highest occurrence of invasive exotics was the Atlantic Forest (948), followed by the Caatinga (423) and Cerrado (334). Most taxa were found in almost all climate classes. Regarding the distribution of species in federal conservation units, C. retusa was present in 40 of them, M. maximus in 20, L. leucocephala in 10, A. heterophyllus in five and P. julifora in four. All species showed higher occurrence in sites with use and occupation of anthropic soils. Our results revealed that the evaluated species have a wide distribution throughout the Brazilian territory and occur in most of the investigated conditions, therefore, it is necessary that public policies are created in order to promote the eradication of these species.
