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 biologis…
The global expansion of arid and semiarid habitats is often associated with climate changes that occurred during the Miocene and Pleistocene. Despite the relevance of these climatic events for the diversification of plants in xeric (dry) environments, few studies have been conducted related to the role of the expansion of aridity as a mechanism of diversification in South America. Besides…
The recent development of new probabilistic methods based on the multispecies coalescent model has enabled the hypothesis testing of species delimitation even in groups that originated recently, with tiny morphological distinction among lineages and complex geographic variation among populations. Among the most diverse genera of Cactaceae in Brazil, Pilosocereus comprises 41 recognized sp…

A large part of the Cactaceae diversity in northeastern Brazil belongs to the Cereinae subtribe, which is marked by uncertainties about the phylogenetic relationships between its constituent genera. Arrojadoa Britton & Rose is one of the genera in Cereinae that exhibits uncertainties about its monophyly and hybrid origin of two species (Arrojadoa albiflora and A. marylaniae), as well as a…
The campo rupestre are highly diverse environments, but they are suffering from predatory human actions and there are still gaps in our knowledge about their diversification processes. To better study these processes, it is essential to obtain phylogenetic information from groups present in this ecosystem. In this project, we will use nuclear genomic data from Cipocereus (Cactaceae), a ge…

The Dry Diagonal is a corridor of open dry formations that separates the Amazon Forest from the Atlantic Forest in South America. Despite the high biodiversity, the mechanisms related to the ecological speciation in these xeromorphic environments are still poorly understood. The use of genomic data integrated with phenotypic and environmental variations stands out as a potential strategy …
The Neotropical region is well known due to its species richness, although how this species richness was established and is maintained is poorly understood. Biotics interchanges were identified in large numbers in the Neotropical regions, indicating a key role for the establishment of regional biota. However, studies about biotic interchange changing the diversification rate are scare in …
Hybridization is a relatively common and important phenomenon in plant evolution. Although it is well documented in taxa of the Cactaceae family, most studies have used only species morphology to investigate the extent of hybridization. For example, the cactus species Pilosocereus arrabidae and P. brasiliensis occur in sympatry on the northern coast of Rio de Janeiro, where they are frequ…

The Neotropical region is well known due to its species richness, but how this biodiversity was established and maintained is still subject to discussion. Biome shifts were identified extensively in the Neotropical region, indicating a key role in the regional biota assembling. However, the role of biome shifts in changing diversification rates in plant lineages from dry and open environ…
