The Espinhaço Range is known for its unique plant diversity and richness of endemic species. We identified the distribution patterns, areas of endemism, floristic similarity, and the areas of richness and diversity of Convolvulaceae within the Espinhaço Range by analyzing a database of approximately 2600 occurrence records. One hundred and eighty-four taxa were categorized into one of four distribution patterns: continuous, disjunct, centered in the Bahia sector, and centered in the Minas Gerais sector. Nineteen Convolvulaceae species are endemic to Espinhaço Range. Endemic species had all of the different distribution patterns. Parsimony analysis of endemism indicated two main centers of endemism for the family: one in the Minas Gerais sector, on the Diamantina Plateau, and another in the Bahia sector, in the Chapada Diamantina. The floristic similarity, richness, and diversity analyses evidenced a principal group in each portion, mainly concentrated in the Chapada Diamantina, and secondarily in the Iron Quadrangle. Such studies are important both for understanding biodiversity and for decision-making in public conservation policies. |
