The organisms show individual geographic distribution patterns that not result of chance. Several past and current events are responsible for the presence of sets of taxa in a given area. The accumulation of events over time makes the reconstruction of the history of the spatial distribution of the biota a complex activity that can be explored in the light of historical biogeography. This approach looks for the correspondence between the phylogenetic relationships of taxa, their geographic distribution and history of Earth. In South America, the diagonal of open landscapes from a broad band stretching from northeastern Brazil to northwestern Argetina including Caatinga, Cerrado, and Chaco. Despite some similarities already detected between these sub-units of the diagonal of open landscapes, there is no consensus about its relations, stressing the importance of historical biogeography studies in these areas. Thus, this project proposes the analysis of the historical relations between the sub-units of the diagonal of open landscapes in South America through geographical data and information on the phylogenetics relationships of snakes. We propose the following specific issues: 1) The Caatinga, Cerrado, and Chaco are a biogeographical unit? 2) What re the historical relationships between these three sub-units in South America? 3) What are the possible geological events and/or modification of the landscape related to the historical connections found between these areas? From these questions, we will test the following hypothesis: common vicariant events between each of the three open areas of South America, Caatinga, Cerrado, and Chaco, and other forested areas make diagonal open a biogeographical area composed, i.e., we expect the Caatinga, Cerrado, and Chaco will not form a natural biogeographical unit. Studies that addressed the history biogeography of the open areas of South America represent a key step towards understanding the evolutionary history of Neotropical biota.
