Cerrado physiognomies in Chapada das Mesas National Park (Maranhão, Brazil) revealed by patterns of floristic similarity and relationships in a transition zone.

The Chapada das Mesas National Park is a federal reserve located in the State of Maranhão, in an ecotonal region of the Brazilian Northeast Cerrado. Aiming to assess the influence of biogeographic patterns and support restoration actions for regions where information is scarce, we analyzed the floristic composition of savanna and forest Cerrado physiognomies, the floristic relationships with other Brazilian Cerrado areas and investigated the floristic relationships between the Cerrado and the Amazon, and the Caatinga and Atlantic Forest biomes. A total of 242 species in 181 genera and 64 families are recorded in our study.
