Vegetational Characteristics in Natural Habitat and Population Structure of the Endangered Plant Tigridiopalma Genus

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
First comprehensive ecological assessment of the endangered genus Tigridiopalma, covering two China endemic Plant Species with Extremely Small Populations (PSESP), T. magnifica and the newly described T. exalata. T. magnifica exhibits broader habitat diversity and understory resilience, while T.

Fern Habitats and Rare Ferns in Oklahoma

open access: yesOklahoma Native Plant Record, 2008
This paper features some of the more common fern habitats in Oklahoma and provides information on four rare Oklahoma ferns from two fern families: Aspleniaceae and Pteridaceae. Surprisingly, ferns can be found in a variety of habitats across Oklahoma.

IUCN Red List Regional Assessment of the Flora of Niue Utilising Indigenous Local Knowledge and Botanical Information

open access: yesJournal of the Royal Society of New Zealand, Volume 56, Issue 2, April 2026.
A regional assessment of the indigenous vascular plants of Niue is presented using the IUCN Red List criteria. The assessment was undertaken during a community workshop that drew on the indigenous local knowledge and scientific information. The assessment comprised 197 named taxa and 8 indeterminate entities, with 4 (2.0%) taxa assessed as Extinct and ...

Evolutionary mobility and genetic dynamics of MORFFO genes: shuttling among ancient plant lineages

open access: yesNew Phytologist, Volume 250, Issue 2, Page 1248-1264, April 2026.
Summary Plastid genomes (plastomes) of land plants are characterized by their architectural and genic content stability. However, fern plastomes exhibit unexpected dynamism, characterized by the presence of mobile protein‐coding genes (CDS) – Mobile Open Reading Frames in Fern Organelles (MORFFOs). We investigate the evolutionary dynamics of MORFFOs in

Plants and Insect Eggs: First Report of a Katydid Using a Fern as Host for Oviposition

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 1, March 2026.
Ferns are the second most diverse lineage of vascular plants worldwide and are particularly abundant in tropical forests. However, the ecological significance of such remarkable diversity has been often underestimated. In this article, we report for the first time the observation of ferns, specifically Polytaenium cajenense (Desv.) Benedict ...

Validation of the family name Pteridaceae

open access: yesWebbia, 1982
Summary Recent research has shown that the name Pteridaceae cannot be used even if the family is circumscribed in a narrow sense. A Latin description of the family is provided in order that the name Pteridaceae be qualified to be conserved.

Adaptive Significance of Nickel Hyperaccumulation by Plants

open access: yesEcological Research, Volume 41, Issue 2, March 2026.
Metal hyperaccumulation may enhance plant fitness through multiple, non‐exclusive mechanisms, including elemental defense against herbivores and pathogens, altered pollinator interactions, and increased reproductive performance in metal‐rich soils. Metals may also affect plant–plant interactions via elemental allelopathy and improve stress tolerance ...

Gametophytic phase of "Doryopteris triphylla" (Pteridaceae, Polypodiopsida).

open access: yesBotanica Complutensis, 2016
Gametophytes of the Pteridaceae are moderately well known but there is still a quite large set of species to describe. Among these is Doryopteris triphylla, a member of the cheilanthoid clade (subgroup hemionitids). The main objective of this work is to describe the gametophyte of D. triphylla.

Undervalued Ecosystems: Ponds Boost Regional Macrophyte Diversity

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Ponds—depressional wetlands with ≤ 2 ha—are largely undervalued worldwide, despite serving as crucial diversity reservoirs. However, the extent to which ponds support diversity at the landscape scale is still underappreciated. Here, we investigate the contributions of ponds to macrophyte beta and gamma diversity in a subtropical wetland ...
