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 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 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…
Despite the high diversity and levels of endemism in the xeric enclaves scattered throughout the Brazilian Cerrado biome, the mechanisms of diversification in these environments are still poorly understood. Among the plant taxa ecologically restricted to these xeric enclaves, the group of cactus species PILOSOCEREUS AURISETUS is composed by eight species exhibiting disjunct distribution i…
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 …
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 convergent evolution and phenotypic plasticity highly observed in the family Cactaceae make the understanding of the systematic and evolutionary history of its taxa very difficult. As a way to deal with this challenge, systematic studies of the family have been focusing on the use of molecular data to develop phylogenetic hypotheses. One of the taxa of Cactaceae that carries a conflic…
