Associated to the scholarship:10/09473-0 - Revision, phylogeny and biogeography of the clade Myrcia pulchra Group (Myrcia s.l., Myrtaceae), BP.DR


The tribe Myrteae contains the neotropical species of Myrtaceae and shows remarkable taxonomic complexity, thus resulting in difficult identification of their taxa. The tribe comprises 49 genera and about 2500 species. Lucas et al. (2007) propose 7 clades inside Myrteae, among which is "Myrcia Group" (=Myrcia s.l.), comprising about 700 species and exclusively neotropical. The phylogenetic study of Lucas et al. (2011) shows 9 clades in "Myrcia Group", one of them been the "Pulchra" clade, containing 30 species distributed mainly in mountain areas of the Atlantic Forest, Cerrado and Guiana Shield. This Project aims to conclude the nomenclatural revision of the "Pulchra" clade, to obtain molecular data and to carry out phylogenetic and biogeographic analyses of this clade. The importance of this study is based on the lack of taxonomic, phylogenetic and biogeographic studies concerning this group, one of the most diverse of the neotropical flora. European herbaria containing type specimen of the study group will be visited for the nomenclatural revision. Molecular sequences (ETS, ITS, psbA-trnH e trnL) will be extracted, amplified and sequenced in order to be used in the phylogenetic analyses (Parsimony and Bayesian), conducted according to the procedure described in Lucas et al. (2011). The morphological and molecular characters will be analysed separately and in a combined analysis. The biogeographic study will be based on the phylogenetic analyses; DIVA, DEC and molecular dating methods (e.g., BEAST) will be used to complete it. The project will be developed in the Royal Botanic Garden of Kew together with Dr. Eve Lucas, one of the specialists in the Systematics of neotropical Myrtaceae. (AU)
