Contribution of High Resolution FTIR imaging for the study of changes of wood components during sucessive ring formation...

Age-related variation in carbon allocation at tree and stand scales in beech (Fagus sylvatica L.) and sessile oak (Querc...

Published in Tree physiology

Two types of physiological mechanisms can contribute to growth decline with age: (i) the mechanisms leading to the reduction of carbon assimilation (input) and (ii) those leading to modification of the resource economy. Surprisingly, the processes relating to carbon allocation have been little investigated as compared to research on the processes g...

Sensitivity of French temperate coniferous forests to climate variability and extreme events (Abies alba, Picea abies an...

Questions: (1) How do extreme climatic events and climate variability influence radial growth of conifers (silver fir, Norway spruce, Scots pine)? (2) How do elevation and soil water capacity (SWC) modulate sensitivity to climate? Location: The sampled conifer stands are in France, in western lowland and mountain forests, at elevations from 400 to ...

Variation of wood density and hydraulic properties of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) clones related ...

Drought response of three Douglas-fir clones (slow, intermediate and fast growing) inhabiting two different climatic regimes in France was examined. We used the hydraulic conductivity and the percent loss of conductivity due to embolism from stems and branches as well as wood microdensity measurements to determine the role of genetics in the contro...

Changes in environmental controls on the growth of Abies alba Mill. in the Vosges Mountains, north-eastern France, durin...

We analyse the radial growth of silver fir (Abies alba Mill.) in the Vosges mountain in north-eastern France in relation to soil, climate and interspecific competition factors and to check the temporal stability of their effects during the 20th century. Data were collected from 143 plots regularly distributed over three altitude ranges (from 330 to...

Tree-ring responses to interannual climate variability within the Fluxnet-Canada network: an isotope approach

Tree-ring width provides a retrospective record of the amount of growth that has taken place during one year. Carbon isotope composition in tree-rings provides an integrated record of the balance between CO2 assimilation rate and stomatal conductance during the period in which the ring was produced. We compared the influence of climatic variations ...

Relationships between tree increment, climate and above-ground biomass of grass: a case study in the typical steppe, nor...

Meyer spruce (Picea meyeri Rehd. et Wils.) is a relict conifer, and Chinese leymus (Leymus chinensis [Trin.] Tzvel.) is a dominant grass in typical steppe of the Xilin River Basin, northern China. Herein, we evaluated the relationships between tree-ring width index of Meyer spruce, climate and above-ground biomass of Chinese leymus, and reconstruct...
