Coupled decline in growth and fine‐branching signals the onset of drought‐induced European beech mortality

open access: yesNew Phytologist, EarlyView.
Conceptual synthesis of drought‐induced mortality in European beech. Summary Severe and recurrent droughts have caused widespread canopy decline and mortality in European forests. Drought‐induced mortality occurs when structural damage and physiological dysfunction impair a tree's ability to recover, yet it remains unclear when trees transition from ...

The Ash Dieback Pathogen Resists the Chemical Defences of Its Host Tree, European Ash, by Depleting Them From the Growth Medium

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plant pathogenic fungi are major drivers of disease in forest trees, often causing substantial ecological and economic damage. Ash dieback, caused by the ascomycete Hymenoscyphus fraxineus, has resulted in the widespread decline of Fraxinus excelsior populations throughout Europe.

Mobile mapping and GeoSLAM for the characterisation and modelling of karst morphologies at the conduit scale

open access: yes
Predicting contaminant and solute transport, forecasting floods and modelling speleogenetic stages are key questions of karst hydrogeology for which some theoretical foundations are still missing.

The impact of seasonal variations in inner bark width and xylem growth on irreversible annual stem diameter measurements

open access: yesPlant Biology, EarlyView.
The seasonal variation in inner bark width differed from that of xylem growth, indicating that xylem phenology cannot be reliably assessed without cellular observations. Abstract To better interpret continuous xylem growth measurements from dendrometers, we evaluated how the widths of developing xylem and phloem, along with seasonal trends in inner ...

Stress‐specific metabolic and physiological responses to drought and waterlogging in Allium cepa L. and Allium × cornutum Clementi ex Vis.

open access: yesPlant Biology, EarlyView.
Drought and waterlogging induce distinct species‐specific metabolic, physiological and transcriptional responses in Allium cepa and Allium × cornutum. Abstract Increasing variability in water availability, caused by changing climatic conditions, is a major constraint for onion production.

A Simple Method to Quantify Bedrock Map Error

open access: yesTerra Nova, EarlyView.
ABSTRACT Geologic maps are foundational to geology. However, most geologic map contacts lack quantitative estimates of uncertainty, typically displaying known contacts as a solid line and uncertain contacts as a dashed line. To address this gap, an easily applied method is presented that provides a quantitative measure of the location of a mapped ...

‘I think it's a rebrand…’: Pre‐service teachers' conceptualisations of adaptive teaching and differentiated instruction

open access: yesJournal of Research in Special Educational Needs, Volume 27, Issue 1, January 2027.
Abstract This paper explores how pre‐service teachers (PSTs) conceptualise adaptive teaching in relation to differentiation within the contemporary policy landscape in England. Drawing on qualitative focus group data and informed by Bourdieu's theory of practice, the study examines how pedagogical understandings are shaped by social justice concerns ...

Karst

open access: yes
Le mot karst est le toponyme germanisé de Kras, une région de plateaux calcaires appartenant aux Alpes dinariques (Slovénie). L’ouvrage de Jovan Cvijic [Das Karstphänomen, 1893] a fait rentrer ce terme dans le vocabulaire scientifique. Il désigne désormais tous les modelés superficiels et souterrains issus de la dissolution par l’eau des roches ...

Schismatoglottideae (Araceae) of Borneo LXXXII: Six New Species of Borneoa

open access: yesFeddes Repertorium, Volume 137, Issue 4, December 2026.
ABSTRACT Six new species of the genus Borneoa (Araceae: Schismatoglottideae) are described from Borneo, increasing the number of accepted species to 30. The new taxa are distinguished by a combination of vegetative and reproductive characters, including leaf morphology, anthomorph structure, spathe and spadix proportions, and floret details.
