Demographic and Structural Variability Modulate Growth Dynamics in European Beech Primary Forests

open access: yesGlobal Change Biology, Volume 32, Issue 5, May 2026.
Climate change is increasing drought and heat stress on European beech (Fagus sylvatica L.), causing widespread tree vitality losses and growth declines across Europe. Using a large tree ring network from montane primary beech forests, we found that trees of various ages and sizes respond differently to climate warming, leading to contrasting within ...

Modeling Acidification Recovery on Threatened Ecosystems: Application to the Evaluation of the Gothenburg Protocol in France [PDF]

open access: yes, 2007
To evaluate the acid deposition reduction negotiated for 2010 within the UNECE LRTAP Gothenburg Protocol, sulphur and nitrogen deposition time-series (1880–2100) were compared to critical loads of acidity on five French ecosystems: Massif Central basalt (

Micropropagation of hornbeam (Carpinus betulus L.) and ash (Fraxinus excelsior L.)

open access: yesBiologia Plantarum, 1990
Shoot multiplication of hornbeam was stimulated onWPM, QL andDKW medium supplemented with a low concentration of BAP or BPA (0.1-0.2 mg I -1) andIBA (0.1 mg I -1). Low concentration of thidiazuron promoted axillary bud formation, higher concentration inhibited shoot elongation.

Nutrition Status of Trees on Spoil Heaps After Coal Mining Can Be Inferred From Seasonal Dynamics of Foliar Nutrient Concentrations

open access: yesLand Degradation &Development, Volume 37, Issue 7, Page 2583-2596, 30 April 2026.
ABSTRACT A stable vegetation cover on given habitat conditions can be one of the possible requirements for post‐mining sites, as it can prevent erosion and dustiness of these anthropogenic surfaces and bring several practical future benefits, such as biomass production and microclimate improvement.

Continuous Stem Water Potential Measurements With Microtensiometry Reveal Species Identity and Soil Matric Potential Control of Stem Water Potential in Temperate Forests

open access: yesEcohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Water potential gradients govern water fluxes, and plants respond with species‐specific hydraulic traits that influence ecosystem function. While understanding these traits is key to predicting vegetation responses to climate change, traditional methods like the pressure chamber limit temporal resolution and continuity.
