The Dry Diagonal (DD) contains a number of environments including the Caatinga and Cerrado that span over 1/3 the area of Brazil, as well as the Chaco of northern Argentina. Because of its perceived lower biodiversity for many taxa than in better known biomes such as the Amazon basin and the Atlantic forest, evolutionary processes in the DD have received much less attention from biologists, even though the DD, in particular the Cerrado, is likely the most endangered major biome in Brazil. The Dry Diagonal Dimensions Project will take a multilevel trait-based approach to understanding the origins and adaptive processes of plants, animals and fungi in the Brazilian DD. We will use a machine-learning approach to identify traits that facilitate or retard speciation for lineages entering the DD. We will then determine how DD biomes act to filter communities from species pools in adjacent habitats (Amazon, AF and others) using a trait-based community-phylogenetic framework that accounts for random assembly, competition, and habitat filtering. Finally, using next-generation sequencing, we will conduct comparative phylogeographic surveys of multiple lineages, whole-genome re-sequencing and transcriptomics to identify genomic drivers of trait divergence in the DD. Together these studies will identify functional, phylogenetic and genomic drivers of adaptation and phenotypic divergence in one of the most poorly understood but consequential habitats in Brazil.
