Active interventions accelerate native plant recolonization following agricultural abandonment

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our results show that combined canopy thinning and prescribed burning can accelerate natural recolonization in savanna systems. However, additional measures (e.g. seed addition) may be needed for weak‐dispersing species. These findings highlight the utility of integrating passive processes with active interventions to conduct efficient landscape‐scale ...

Selenium reverses Pteridium aquilinum-induced immunotoxic effects

open access: yes, 2011
We have previously shown that bracken fern (Pteridium aquilinum) has immunomodulatory effects on mouse natural killer (NK) cells by reducing cytotoxicity. Alternatively, it has been demonstrated that selenium can enhance NK cell activity.

Forest Plants Decrease in Occupancy and Contract Their Edaphic Niches Towards Their Climatic Range Margins

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 5, May 2026.
ABSTRACT Aim For improved predictions of the redistribution of species under climate change, there is a need to better understand how interactions among multiple abiotic drivers affect species distributions. We examined whether occupancy patterns of forest plant species change consistently along geographic and macroclimatic gradients. We further tested

A First Quantification of Plant Endemism in the Manica Highlands (Zimbabwe–Mozambique) and the Significance of Open Habitats

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We present here the first quantitative assessment of plant endemics from the Manica Highlands (Zimbabwe‐Mozambique), totalling 216 taxa, representing over 9% of the estimated total flora. A major finding is that 173 (80%) endemic taxa are principally or entirely confined to open montane habitats such as grassland, bare rock, crags and scrub or dwarf ...

Modeling Neglected and Underutilized Crops for Future Food Resilience: A Regional MaxEnt Workflow

open access: yesPlant-Environment Interactions, Volume 7, Issue 2, April 2026.
ABSTRACT Increasing agrobiodiversity is a widely supported idea and prevalent topic in academic discussion recently as a means to combat the effects of climate change. However, there is a lack of connection between academic discussion and application.

Glycosyltransferases expression analysis of gastric mucosa from Pteridium aquilinum exposed mice. Panel A –

open access: yes, 2012
Heatmap of the Glyco-gene Chip array analysis obtained when comparing group 1 (control mice) with group 2 (mice treated with Pteridium aquilinum). Red and blue indicate increased and decreased expression relative to the mean transcript expression value ...

Hematologycal, biochemical, Urinary and histopathological changes in natural intoxication in bovine by bracken fern (Pteridium aquilinum) (L.) Kühn/
Alterações hematológicas, bioquímicas, urinárias e histopatológicas na intoxicação natural em bovinos pela samambaia Pteridium aquilnum (L.) Kühn

open access: yesSemina: Ciências Agrárias, 2005
Enzootic hematuria is a cronic disease of cows clinically characterized by intermittent hematuria that can be caused by bracken fern (Pteridium aquilinum) and the papilomatosis virus.

Regionalization of European Habitat Classification (EUNIS) for Effective Ecosystem Assessment

open access: yesApplied Vegetation Science, Volume 29, Issue 2, April/June 2026.
The study presents a regionalization framework for EUNIS habitat classification. We relied on European concepts to define 99 regional ecologically meaningful habitats that were strongly linked to environmental drivers and legal conservation categories.

Detecting Pteridium arachnoideum and Tithonia diversifolia in a Multiclass Land‐Cover Framework in the Cerrado: A Deep Learning Time‐Series Benchmark With Spatial Cross‐Validation

open access: yesTransactions in GIS, Volume 30, Issue 2, April 2026.
ABSTRACT This study presents the first deep‐learning time‐series benchmark for detecting two encroaching species in the Brazilian Cerrado: the native super‐dominant fern Pteridium arachnoideum and the invasive alien shrub Tithonia diversifolia. We evaluate 43 architectures across six families (CNNs, RNNs, Transformers, and three hybrid groups) on ...

Essential oil composition and antibacterial activity of Pteridium aquilinum (L.) Kuhn

open access: yesBiologia Futura, 2019
Introduction The present work aims to study the chemical composition of Pteridium aquilinum (L.) Kuhn essential oil and its antibacterial activity against three important phytopathogenic Gram-negative bacteria: Erwinia amylovora, Pectobacterium ...
