Amazon plant diversity revealed by a taxonomically verified species list
A comprehensive dataset of Amazonian seed plant species from published sources that includes falsifiable data based on voucher specimens identified by taxonomic specialists is assembled, providing a valid starting point for macroecological and evolutionary studies aimed at understanding the origin, evolution, and ecology of the exceptional biodiversity ofAmazonian forests.

Phylogeny of Miconia (Melastomataceae): Patterns of Stamen Diversification in a Megadiverse Neotropical Genus
The major evolutionary diversifications within the Neotropical tribe Miconieae have been obscured by convergence in stamen morphology, leading to many arbitrary generic and sectional circumscriptions. Expand
Studies on the reproductive biology ofMelastomataceae in “cerrado” vegetation
Controlled pollinations and observations of pollen tube growth, pollen fertility and cytological data were studied in 11 species of Melastomataceae growing in “cerrado” in SE Brazil, suggesting the existence of very extensive apomictic complexes comparable to those reported in mainly temperate genera of Asteraceae andRosaceae.

How long does the Atlantic Rain Forest take to recover after a disturbance? Changes in species composition and ecological features during secondary succession
We evaluated floristic and ecological changes in plant communities after disturbance in Southern Atlantic Rain Forests, in the Brazilian states of Rio de Janeiro, Sao Paulo, Parana´ and SantaExpand
Multiple Events of Dispersal and Radiation of the Tribe Miconieae (Melastomataceae) in the Caribbean
A phylogenetic analysis of 460 accessions from 450 species of the tribe Miconieae shows that most of the Caribbean endemics are the product of five radiation events: a clade containing the Caribbean endemic (or near-endemic) genera Pachyanthus, Calycogonium, Tetrazygia and Charianthus, as well as a few representatives of Miconia and Leandra.

A phylogenetic evaluation of Leandra (Miconieae, Melastomataceae): a polyphyletic genus where the seeds tell the story, not the petals
An analysis of nrITS sequence data for a sample of 63 species of Leandra shows that Seed appendages in Leandra have evolved independently at least four times and are better correlated with the phylogeny than traditional characters, such as petal morphology. Expand
Pattern of tree species diversity in riparian forest fragments of different widths (SE Brazil)
The existence in riparian corridors of a drier forest, in general richer and more diversified than the annually flooded forest, seems to favor the maintenance of regional species diversity in fragmented landscapes. Expand
Nomenclator botanicus for the neotropical genus Miconia (Melastomataceae: Miconieae)
This nomenclator attempts to enumerate all currently accepted species of Miconia with place of publication, information on types, synonymy, sectional placement, and distributional notes organized by country. Expand
Flower color change accelerated by bee pollination in Tibouchina (Melastomataceae)
Abstract Floral color changes are common among Melastomataceae and have been interpreted as a warning mechanism for bees to avoid old flowers, albeit increasing long-distance flower display. Here theExpand
Shifts from specialised to generalised pollination systems in Miconieae (Melastomataceae) and their relation with anther morphology and seed number.
In actinomorphic small-flowered Miconieae, changes in anther morphology can be related to generalisation in the pollination system incorporating flies and wasps as pollinators and lessening the importance of buzzing bees in such process. Expand
