Lista y conservación de la flora en un área ecotonal de la microregión del Bico do Papagaio, estado de Tocantins, Brasil

The Amazon and Cerrado biomes form a wide and complex savanna–forest ecotone, particularly in northern Brazil. The Bico do Papagaio micro-region is an important area of biodiversity due to its floristic diversity. This study aimed to provide a species list of Angiosperm Flora of Bico do Papagaio micro-region, Tocantins state, Brazil. The species list was compiled from Brazilian and international herbaria, in collections available in Reflora Herbário Virtual and SpeciesLink. A total of 928 species, distributed in 475 genera and 117 families were reported to Bico do Papagaio micro region. The families with the greatest number of species were Fabaceae (148 species), Poaceae (63), Euphorbiaceae (38), Myrtaceae (26), Bignoniaceae (22), Malvaceae (24), Melastomataceae (26), Cyperaceae (29), Convolvulaceae (24) and Apocynaceae (23). The families were highlighted due to ecotonal characteristics of the studied area, since those are plants easily found on these biomes, as well as diverse phytogeographic domains, since they easily adapt to diverse environments, like Cerrado and Amazon. This study indicates the importance of specific data species compilation from herbaria collections to comprehend the already historical record of species in the region and which are no longer collected, be it for low data collection effort or the extinction of these species.
