This page lists the scientific contributions of an author, who either does not have a ResearchGate profile, or has not yet added these contributions to their profile.
It was automatically created by ResearchGate to create a record of this author's body of work. We create such pages to advance our goal of creating and maintaining the most comprehensive scientific repository possible. In doing so, we process publicly available (personal) data relating to the author as a member of the scientific community.
If you're a ResearchGate member, you can follow this page to keep up with this author's work.
If you are this author, and you don't want us to display this page anymore, please let us know.

Phylogenetic analyses show that a group of species of Miconia (Melastomataceae: Miconieae) from the Greater Antilles
all form a clade. They share the presence of backward-deflexed filaments with the entire androecium turning pink to red after
anthesis and placentation reduced axile to basal. Additionally, many of these species are deciduous, and ha...
The Neotropics harbor over a third of all known seed plant species, and their distribution is not homogenous. Understanding how this diversity arose and is maintained is a complex endeavor and likely dependent upon the area, vegetation type, or group of organisms studied. The Miconieae, with ca. 1900 species, are the largest tribe of the plant fami...
Improved quantification of species’ ranges is needed to provide more accurate estimates of extinction risks for conservation planning. Highland tropical biodiversity may be particularly vulnerable to the anthropogenic changes in land cover and climate and is subject to overestimation of geographic range size in IUCN assessments. Here, we demonstrat...

... Naudin a sexual species (Maia et al. 2016). Although Miconia has been widely studied in systematics and phylogeny (Michelangeli et al. 2019), reproductive biology (Goldenberg and Shepherd 1998;Caetano et al. 2013;Caetano et al. 2018), and biogeography (Caddah et al. 2022;Michelangeli et al. 2022b), its investigation in the field of culture of plant tissues in vitro is still limited. Prudente et al. (2016Prudente et al. ( , 2017 contributed with an in vitro culture protocol via indirect organogenesis and cryopreservation for Miconia ligustroides (DC.) ...

... It is important to note that forest cover can change over time and is crucial for habitat specialists with limited vagility across non-habitat areas, such as arboreal primates. Therefore, model-based range maps can be adjusted to exclude areas that currently lack the necessary cover (Gavrutenko et al., 2021). To ensure accuracy, we overlaid all records with a deforestation raster updated in 2022 at a spatial resolution of 30 m, which covered the entire study region. ...

... Supporting the link between herkogamy and self-pollen deposition, our RF model indicated that herkogamy was the major predictor of self pollination in Miconia species, also indicating self pollination in both AF-endemic and nonendemic Miconia species of our study system (Figure 4). This trend toward reduced herkogamy has been recorded across other Miconia lineages (Gavrutenko et al., 2020), suggesting an overall increase in self pollination in this genus. An increase in self pollination has been thought to reflect frequent failure of cross pollination (Goodwillie et al., 2005), representing a reproductive assurance strategy (Busch and Delph, 2012). ...
