A re-analysis of their data rather led us to conclude that, when accounting for the singular effect of storm Klaus, the rate of change in harvested area depended on the change year used to separate the two periods to compare. Moreover, the comparison with data on harvested volumes from different sources brought contrasted results depending on the source. Therefore, it cannot be concluded that wood harvest increased in France in 2016–2018 compared to 2004–2015. The discrepancy between Ceccherini et al.’s data and other data on harvested volumes points out the difficulty of reconciling different approaches to estimate wood harvest at a country level.

Diversity of water use efficiency among Quercus robur genotypes: contribution of related leaf traits / Magali Roussel in Annals of Forest Science, Vol 66 n° 4 (June 2009)

In the present study, twelve genotypes with extreme phenotypic values of Δ13C were selected within this family to (i) asses the stability of genotype differences across contrasting environments and for different measures Wi; (ii) quantify the relationship between Δ13C and Wi within this family; (iii) identify which leaf traits drive the diversity in Wi observed in this family. Genetic variability of Δ13C and Wi was largely independent from different temporal integration scales and their correlation was found to be strong (R2 = 88% for leaf sugars) within this family. Weak correlations between measures of Wi with estimators of photosynthetic capacity, suggest a minor role of the latter in the diversity of Wi. However, the tight correlation between gs and Δ13C as well as Wi, and the related genotypic variation in stomatal density, suggest that the genotypic diversity in Wi within this pedunculate oak family might be due to differences in gs.
