Quantifying competition in white spruce (Picea glauca) plantations.
By Erwin Dreyer On 27 March 2017 In Research paper
In mixed forest plantations in sub-boreal forests with high levels of natural regeneration ingrowth, competition must be quantified differently for each species, with distant-independent indices working better for the planted species and distant-dependent indices for ingrown balsam

A critical analysis of methods for rapid and nondestructive determination of wood density in standing trees
By Erwin Dreyer On 27 March 2017 In Research paper
Field methods for rapid determination of wood density in trees have evolved from increment borer, torsiometer, Pilodyn, and nail withdrawal into sophisticated electronic tools of resistance drilling measurement. A partial resistance drilling approach coupled with knowledge of

Forward selection in a maritime pine polycross progeny trial using pedigree reconstruction
By Erwin Dreyer On 9 March 2017 In Research paper
Molecular markers were used for paternity recovery in a maritime pine (Pinus pinaster Ait.) polycross trial, facilitating forward selection. Different breeding strategies for seed orchard establishment were evaluated by comparing genetic gains and diversity. This work opens

Modelling wood formation and structure: power and limits of a morphogenetic gradient in controlling xylem cell proliferation and growth
By Erwin Dreyer On 9 March 2017 In Research paper
The emergence of the characteristic tree-ring pattern during xylogenesis is commonly thought to be controlled by a gradient of morphogen (auxin, TDIF peptide…). We show that this hypothesis accounts for several developmental aspects of wood formation, but

Changes of secondary metabolites in Pinus sylvestris L. needles under increasing soil water deficit
By Erwin Dreyer On 9 March 2017 In Research paper
A multiphasic response to water deficit was found in Scots pine primary and secondary metabolism. First, an increase of terpenoids coincided with the stomatal closure. Second, an accumulation of proline, ABA, and shikimic acid was detected when

Improving the utility, performance, and durability of wood- and bio-based composites
By Erwin Dreyer On 9 March 2017 In Review paper
This paper briefly reviews the state of the art in various types of wood- and bio-based composites, summarizes recent advances, and then discusses future possibilities for improving the durability of wood- and bio-based composites. Abstract Wood can

Mortality, re-sprouting vigor and physiology of coppice stumps after mechanized cutting
By Erwin Dreyer On 13 February 2017 In Research paper
Mechanized cutting may result in higher stump damage levels, especially if cutting is performed with shears. Nevertheless, stumps cut with mechanized technology do not show higher mortality rates than do stumps cut manually with a chainsaw. One-year

Site factors as predictors for Pinus halepensis Mill. productivity in Spanish plantations
By Erwin Dreyer On 12 February 2017 In Research paper
This work presents a discriminant model to predict Pinus halepensis forest productivity using parameters related to water availability (Annual Hydric Index, soil porosity and slope) and information about the N immobilization by soil microorganisms (microbial biomass N).

Model performance of tree height-diameter relationships in the central Congo Basin
By Erwin Dreyer On 12 February 2017 In Research paper
Tree heights in the central Congo Basin are overestimated using best-available height-diameter models. These errors are propagated into the estimation of aboveground biomass and canopy height, causing significant bias when used for calibration of remote sensing products
