Quantifying the Earth’s forest above-ground biomass (AGB) is indispensable for effective climate action and developing forest policy. Yet, current allometric scaling models (ASMs) to estimate AGB suffer several...

Drought response of European beech trees is not straight forward
Drought and rising temperatures can cause massive forest diebacks around the world. When a tree is experiencing drought, “shedding off” the leaves can enhance tree water status by reducing canopy transpiration. Whilst...

Core business: X-ray CT toolchain for tree-ring analysis
Disentangling tree growth requires more than ring width only. Although X-ray densitometry is an established technique to determine key wood density parameters, tedious manual procedures hamper fast analyses. De Mil et...
Temperature responses of photosynthesis under elevated CO2
Plants growing under elevated atmospheric CO2 concentrations often have reduced stomatal conductance and subsequently increased leaf temperature. Šigut et al. find that this is indeed the case for broadleaved Fagus...
Responses of beech and spruce foliage to elevated carbon dioxide, increased nitrogen deposition and soil type
Although enhanced carbon fixation by forest trees may contribute significantly to mitigating an increase in atmospheric CO2, capacities for this fixation vary greatly among different tree species and locations. In a...

Density × species evenness effects on coexistence and growth
Collet et al. study a tree plantation that mixes beech and sycamore according to a double gradient of density and species’ proportion, and find that density and tree size are the primary factors determining individual...
Water stress, xylem hydraulic failure and tree death
The results of this study demonstrate that massive cavitation is probably a causal factor for tree mortality under extreme water stress conditions.
Light and competition fail to explain seedling coexistence
The coexistence of forest tree species has often been linked to differences in their response to light availability during the regeneration stage. Van Couwenberghe et al. study natural regenerated shade-tolerant Fagus...
Trunk epicormics and growth in Fagus sylvatica
Epicormic shoots in European beech, Fagus sylvatica, may be associated with decreased radial growth. Colin et al. study the number of axillary buds, shoot length, ring width profiles, epicormic shoots and other...
CO2 effects on reproduction versus vegetative growth
Increased atmospheric CO2 concentrations may affect competition for resources between reproduction and shoot growth in forest species. Han et al. examine mature beech (Fagus sylvatica) trees in masting and non-masting...
Stem uprighting in tree saplings
Tree saplings growing in a forest understorey undergo frequent changes in their light environment, to which they must adapt. Collet et al. analyse changes in sapling stem inclination over 4 years after canopy opening in...
