Evidence of climate effects on the height-diameter relationships of tree species
By Isabelle Fabrissin On 12 February 2019 In All published articles, Data in repository, Research paper, Special issue/Topical collection
The mean temperature from March to September affects the height-diameter relationship of many tree species in France. For most of these species, the temperature effect is nonlinear, which makes the identification of an optimal temperature possible. Increases

Soil aggregation may be a relevant indicator of nutrient cation availability
Aggregation was studied in two acidic forest soils (NE France) to investigate the potential link between available Ca and Mg content and soil aggregate size distribution and properties. Clay content influenced the aggregation status while clay mineralogy

Performance of strength grading methods based on fibre orientation and axial resonance frequency applied to Norway spruce (Picea abies L.), Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) and European oak (Quercus petraea (Matt.) Liebl./Quercus robur L.)
Machine strength grading of sawn timber is an important value adding process for the sawmilling industry. By utilizing data of local fibre orientation on timber surfaces, obtained from laser scanning, more accurate prediction of bending strength can

Below-ground hydraulic constraints during drought-induced decline in Scots pine
By Isabelle Fabrissin On 8 February 2019 In All published articles, Data in repository, Research paper
Below-crown hydraulic resistance, a proxy for below-ground hydraulic resistance, increased during drought in Scots pine, but larger increases were not associated to drought-induced defoliation. Accounting for variable below-ground hydraulic conductance in response to drought may be needed

Can forest structural diversity be a response to anthropogenic stress? A case study in old-growth fir Abies alba Mill. stands
From 1973 to 1991, Polish SO2 emissions above 3250 Gg/year resulted in a decline of fir Abies alba Mill. After stresses connected with these emissions, five main diameter at breast height (DBH) structural types were described. This
