Areas of endemism of Pteridaceae (Polypodiopsida) in Brazil: a first approach

Cladistics, 2023
Areas of endemism (AoE) comprise regions host to two or more endemic taxa, whose distributional limits are congruent and not random. These areas are important for two reasons: they comprise the smallest geographic units for biogeographic analyses and ...

Adiantum viscosum (Pteridaceae), a new species endemic to sclerophyllous forest of Central Chile

Phytotaxa, 2023
Adiantum viscosum (Pteridaceae) is a new species of fern endemic to Central Chile that inhabits the sclerophyllous forest of the Valparaíso Region. Adiantum viscosum is morphologically similar to A. gertrudis and A.

An updated account of Adiantum (Pteridaceae: subfamily Vittarioideae) in Thailand

Australian Systematic Botany, 2023
An updated account of Thailand’s maidenhair ferns, Adiantum L. (Pteridaceae), is presented. The genus consists of 20 taxa, including 19 indigenous and 1 naturalised, distributed in various habitats throughout Thailand, and 5 of them are endemic.

Resolving Deep Relationships and Revealing Ancient Whole-Genome Duplications in Pteridaceae using Transcriptomic Data

American Fern Journal, 2023
. Relationships among the major subclades in the fern family Pteridaceae have proven difficult to resolve. Here, we examine the backbone of this large and heterogeneous lineage using both phylotranscriptomic methods and a more focused, curated approach ...

Integrative taxonomy supports the recognition of four taxa in the Notholaena trichomanoides complex (Pteridaceae) in Cuba

Biological Journal of the Linnean Society, 2023
With nearly 40 species, the fern genus Notholaena has its evolutionary centre in the deserts of Mexico and the southwestern United States. Previous studies have focused on assessing the monophyly of the genus and the patterns of farina evolution, but ...

Green Synthesis of Silver‐Doped ZnO Nanoparticles From Adiantum venustum D. Don (Pteridaceae): Antimicrobial and Antioxidant Evaluation

Journal of Basic Microbiology
One of the main difficulties in nanotechnology is the development of an environmentally friendly, successful method of producing nanoparticles from biological sources. Silver‐doped zinc oxide nanoparticles (Ag‐ZnO NPs), with antibacterial and antioxidant

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

Journal of Biogeography
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

Phylogeny and systematics of the fern genus Pellaea and its allies (Pteridaceae)

Phytotaxa
The pellaeid ferns constitute a monophyletic, xeric-adapted lineage in the large fern family Pteridaceae. Previous studies, with relatively small taxon and character sampling, resolved the major relationships in the pellaeid ferns and found the most ...

A phylogenetically informed generic reclassification of the hemionitid ferns (Pteridaceae: Cheilanthoideae)

Taxon
The roughly 500 species of cheilanthoid ferns exhibit a diversity of morphological adaptations to xeric environments. However, most of these traits have evolved independently multiple times, impeding past efforts to establish a natural classification for
