5. Discussion
- 26 bioregions, including BNMF.
- Common and exclusive species: Byrsonima coccolobifolia, Manilkara
rufula, Wedelia villosa e Guettarda angelica.
Indicative species: Guettarda angelica, Byrsonima coccolobifolia,
Eschweilera apiculata and Manilkara rufula.
- Our results indicates that past connections between the Neotropical
rainforests resulted from specific climatic conditions and support BNMF as
an unique biogeographical region as they were shaped by different climate
conditions.
