Stamen dimorphism in bird‐pollinated flowers: Investigating alternative hypotheses on the evolution of heteranthery

Evolution, Volume 75, Issue 10, Page 2589-2599, October 2021., 2021
Abstract Heteranthery, the presence of distinct stamen types within a flower, is commonly explained as functional adaptation to alleviate the “pollen dilemma,” defined as the dual and conflicting function of pollen as pollinator food resource and male reproductive agent.

Molecular phylogenetics of the Dissochaeta alliance (Melastomataceae): Redefining tribe Dissochaeteae

TAXON, Volume 70, Issue 4, Page 793-825, August 2021., 2021
Abstract The Dissochaeta alliance (= subtribe Dissochaetinae) is a group of woody climbing taxa within tribe Dissochaeteae (Melastomataceae) and comprises 90 species mainly distributed in Southeast Asia. The circumscription of the alliance and its genera has been problematic when based on only morphological characters. With a broad sampling of relevant

A nuclear phylogenomic study of the angiosperm order Myrtales, exploring the potential and limitations of the universal Angiosperms353 probe set

American Journal of Botany, Volume 108, Issue 7, Page 1087-1111, July 2021., 2021
Premise To further advance the understanding of the species‐rich, economically and ecologically important angiosperm order Myrtales in the rosid clade, comprising nine families, approximately 400 genera and almost 14,000 species occurring on all continents (except Antarctica), we tested the Angiosperms353 probe kit.

Low bee visitation rates explain pollinator shifts to vertebrates in tropical mountains

New Phytologist, Volume 231, Issue 2, Page 864-877, July 2021., 2021
Summary Evolutionary shifts from bee to vertebrate pollination are common in tropical mountains. Reduction in bee pollination efficiency under adverse montane weather conditions was proposed to drive these shifts. Although pollinator shifts are central to the evolution and diversification of angiosperms, we lack experimental evidence of the ecological ...

Comparison of DPPH Free Radical Scavenging, Ferric Reducing Antioxidant Power (FRAP), and Total Phenolic Content of Two Meriania Species (Melastomataceae)

Revista de Ciencias, 2015
Searching for new antioxidants used in pharmaceuticals, cosmetics or agrochemicals have increased  today.  Many  phenolic  compounds  have  been  reported  as  promising  for  this  goal. Melastomataceae is rich in these compounds. Consequently, in this

Phylogenomic use of low‐copy nuclear markers from genome skimming data: An example from Melastomataceae

TAXON, Volume 75, Issue 2, April 2026.
Abstract The emergence of conflicting signals among different genomic regions, individual genes, and inference methods has been frequently reported in phylogenomic studies. Conflicts can occur from methodological error and biological processes, and disentangling the contribution of each putative source of discordance became a major challenge.
