Speciation, dispersal and the build‐up of fern diversity in the American tropics

open access: yesEcography, Volume 2025, Issue 11, November 2025.
Understanding how the remarkable biodiversity of the American tropics developed has been a long‐standing question, yet knowledge gaps remain. Previous studies examined the roles of bioregions in shaping diversity patterns but often overlooked speciation, a critical driver of species richness, and insufficiently accounted for temporal changes in ...

TRB proteins in moss reveal their evolutionarily conserved roles in plant development and telomere maintenance

open access: yesThe Plant Journal, Volume 124, Issue 3, November 2025.
Significance Statement TRB proteins in the moss P. patens are essential for normal development, telomere maintenance, and transcriptional regulation. Our findings demonstrate the evolutionary conservation of TRB functions across land plants and highlight their ancient origin in streptophytes.

Was the Dry Diagonal of South America a Barrier for Dispersing Pteridaceae (Polypodiopsida) Species Between the Brazilian Atlantic Forest and Amazon Forest?

open access: yesJournal of Biogeography, Volume 52, Issue 8, August 2025.
ABSTRACT Aim We sought to assess how phylogenetic patterns within the fern family Pteridaceae are related to the history of the Amazon Forest and the Brazilian Atlantic Forest, as well as the Dry Diagonal of South America. The age of taxa present in these regions was estimated, as well as those found in previously identified areas of endemism for the ...

New insights into the phylogeny of Pleopeltis and related Neotropical genera (Polypodiaceae, Polypodiopsida)

open access: yesMolecular Phylogenetics and Evolution, 2009
The fern family Polypodiaceae plays an important role in Neotropical epiphyte diversity. Most of its American representatives are assembled in a monophyletic clade that, apart from the grammitids, nearly exclusively comprises species restricted to the New World.
