Pteridaceae endémicas del Perú
Esta familia es reconocida en el Perú con 18 géneros y más de 150 especies (Tryon & Stolze, 1989b; Smith et al., 2005). Si bien la familia Pteridaceae es la más rica en especies de la flora pteridofítica peruana; solamente ocho especies en cuatro ...

As pteridófitas exibem forte mecanismo de dominância nas áreas onde crescem, formando associações quase que puras, onde apenas poucas espécies coexistem.

Helechos de Veracruz: Adiantum (Pteridaceae)
En este trabajo se presenta una clave para la identificación de veinte especies del género Adiantum. Aunque tres de las especies no han sido recolectadas en el estado de Veracruz, se sospecha su existencia por encontrarse en áreas vecinas de los estados

Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous-Paleogene boundary in western North America. [PDF]
Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

Diel net CO<sub>2</sub> exchange of carnivorous Pinguicula is consistent with low-level CAM photosynthesis. [PDF]
In carnivorous butterworts (Pinguicula), CO2 uptake occurs primarily in the light via C3 photosynthesis, yet low‐level CAM photosynthesis, including net CO2 dark fixation, significantly improves the carbon balance of plants, especially under water‐deficit conditions.

Genomics is modifying our concepts of evolution in homosporous and heterosporous vascular plants. [PDF]
Abstract Across the tree of life, and particularly within land plants, there is a wide diversity and disparity of genome structure. The most well‐studied are angiosperms, comprising mostly small and dynamic genomes, with a history of ancient whole genome duplications.

<i>Aleuritopteris hainanensis</i> (Pteridaceae), a New Species From Hainan, China. [PDF]
A new fern species, Aleuritopteris hainanensis, is described from Hainan Province, China, closely resembling A. squamosa but differing in fertile/sterile frond length and scale morphology. Plastome analysis confirms its distinctness, showing significant genetic divergence from A. squamosa.
