A classification for extant ferns [PDF]

open access: yes, 2006
We present a revised classification for extant ferns, with emphasis on ordinal and familial ranks, and a synopsis of included genera. Our classification reflects recently published phylogenetic hypotheses based on both morphological and molecular data ...

The role of Alpine botanical gardens in integrating germplasm bank collections and mission

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 680-692, March 2026.
This study underscores the vital role of Alpine botanical gardens (ABGs) in safeguarding Europe's alpine biodiversity amid climate change and habitat loss. By acting as living laboratories and reservoirs of plant genetic resources, ABGs bridge ex situ and in situ conservation, supporting ecosystem resilience and informing restoration strategies.

Was the evolution of faster stomata driven by increased gas exchange rates rather than increasing water use efficiency?

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2355-2371, March 2026.
Summary Following changes in light flux, photosynthesis (A) typically adjusts more quickly than stomatal conductance (gs), which is dependent on changes in stomatal aperture. Faster stomatal responses are proposed to reduce water loss and enhance growth in dynamic light environments. Stomatal opening and closing parameters were determined in a range of

Complete chloroplast genome sequence of the medical fern Drynaria roosii and its phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2017
In this study, the complete chloroplast genome of the medical fern Drynaria roosii was completed and analyzed in order to understand the evolution of the genome of the fern lineages. In D. roosii, the circular double-stranded cpDNA sequence of 154,305 bp

Characterization of the Omnivorous Lygus lineolaris Diet in a Strawberry Field by Metataxonomy

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
This study employs metataxonomy to reveal the extensive omnivorous diet of Lygus lineolaris in a strawberry field, identifying 475 host taxa and confirming active ingestion across plant and prey sources. We introduce a novel coefficient of omnivory, demonstrating the species' strong herbivorous bias while highlighting its dietary flexibility and ...

gen. et sp. nov., a fossil fern in the family Pteridaceae (Polypodiales) from the Cretaceous amber forests of Myanmar [PDF]

open access: yes, 2019
Divergence time estimates suggest that most clades constituting the fern family Pteridaceae (Polypodiales) were in existence by the Early Cretaceous. However, fossil evidence to corroborate this remains exceedingly rare.
