The role of Quaternary glaciations in shaping biogeographic patterns in a recently evolved clade of South American epiphytic orchids.
To contribute to what is known about involvement of vegetation dynamics in Neotropical speciation, we used the Epidendrum latilabre complex, a taxonomically well-defined species group, to investigate past connections between Amazonian (AM) and Atlantic (AF) forests and address the following topics: (1) divergence times between sister species currently distributed in... -

Too many species: morphometrics, molecular phylogenetics and genome structure of a Brazilian species complex in Epidendrum (Laeliinae; Orchidaceae) reveal fewer species than previously thought
In this study, we analyse a species complex in Epidendrum, a mega-diverse Neotropical orchid genus, that is formed by the 11 Brazilian species of the E. difforme group. Although this group (c. 100 taxa) exhibits relatively high levels of floral variation, the Brazilian species are similar, making delimitation problematic. Here... -

Advanced understanding of phylogenetic relationships, morphological evolution and biogeographic history of the mega-diverse plant genus Myrcia and its relatives (Myrtaceae: Myrteae)
Myrcia is the largest exclusively Neotropical genus of the plant family Myrtaceae with c. 770 species. Although several studies have elucidated the relationships within particular sections of the genus, to date no phylogeny has been produced that includes a broad taxonomic and geographic representation. Here we present a phylogenetic hypothesis...Amorim, Bruno ; Vasconcelos, Thais ; Souza, Gustavo ; Alves, Marccus ; Antonelli, Alexandre …
