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

Journal 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 ...

Living in Staghorn Fern Nests Alters the Distribution of Zealandia pustulata (Polypodiaceae) Along an Elevational Gradient on Lord Howe Island

New Zealand Journal of Botany, Volume 64, Issue 1, March 2026.
The staghorn fern (Platycerium bifurcatum, Cav. Polypodiaceae) is an epiphyte that lives in cooperative colonies whose members work together to build a communal water and nutrient store. Previous research has shown that staghorn colonies are sometimes invaded by Zealandia pustulata (G.Forst.

Adetogramma (Polypodiaceae), a new monotypic fern genus segregated from Polypodium

PhytoKeys, 2017
Polypodiaceae is one of the most diverse and abundant families of ferns in tropical and subtropical forests. Despite multiple studies investigating its phylogeny and taxonomy, several generic boundaries within the family still need clarification.

Global Diversification Rates of Ferns Across Spatial and Climatic Gradients

Advanced Science, Volume 13, Issue 3, 14 January 2026.
Diversification rates of fern genera across the phylogeny. Abstract Geographic patterns of diversity in any group of plants are the result of the interplay of environmental conditions and the evolutionary dynamics of the respective plant group. Here, the geographic distribution of current mean diversification rates (MDR) is explored at the genus level ...

Medicinal Plants Used by Tanzanians for Human Paediatric Ailments: A PRISMA‐Guided Systematic Review of Ethnomedicinal Evidence

The Scientific World Journal, Volume 2026, Issue 1, 2026.
Paediatric ailments (PAs) pose an increasing health and economic challenge in many low‐ and middle‐income countries. In Tanzania, over 80% of the rural population relies on traditional medicine for primary healthcare. Although documentation of medicinal plants (MPs) used to treat and manage PAs remains fragmented, this systematic review consolidates ...

Water availability and evolutionary similarity shape the global distribution of ferns with chlorophyllous spores

Ecography, Volume 2025, Issue 11, November 2025.
About 14% of all fern species have chlorophyllous spores, which lack dormancy, have thin walls, and have a shorter viability (only a few days in some species). These spores should have limited dispersal distances and be more susceptible to harsher climatic conditions, raising questions about the evolutionary and ecological significance of this trait ...
