Abstract

Velloziaceae comprises five genera and approx. 250 species, mostly amphiatlantic. The majority of species is Neotropical, and in Brazil, the family is represented by Barbacenia and Vellozia, comprising 213 species. In recent phylogenetic reconstructions using Bayesian and Parsimony inferences, Barbacenia formed two basal clades. One of them, the Barbacenia inselbergs clade, comprises only endemic species from Brazilian inselbergs s.l., such as Barbacenia fanniae, B. gounelleana, B. irwiniana, B. mantiqueirae, B. purpurea, and B. spectabilis. Its sister clade includes the other 44 species of Barbacenia analyzed, all from the Campo Rupestre Archipelago, in central/south-eastern Brazil. Given this scenario, this internship aims to obtain data in order to understand the biogeographic history of the Barbacenia inselbergs clade. For these studies we propose: (i) to use phylogenetic inferences based on molecular and morphological data of Barbacenia inselbergs clade plus external group consisting of Barbacenia species from Campos Rupestres, and species of Vellozia, Barbaceniopsis, Xerophyta, Acantoclamys, Cyclanthaceae, and Pandanaceae, to obtain a robust time-tree for these terminals; (ii) to gather geo-referenced locality datasets and elaborate distribution maps for the species; (iii) to perform analysis of reconstruction of the ancestral area. This proposal will be developed during a BEPE at the Nees-Institut für Biodiversität der Pflanzen, Universität Bonn, Germany, which houses an important research group of studies on plant systematics and evolution, taxonomy, biogeography and conservation.
