Adaptation of trembling aspen and hybrid poplars to frost and drought: implications for selection and movement of planting stock in western Canada
DownloadFall 2012
This study contains a series of experiments to evaluate growth performance and survival of hybrid poplars (Populus spp.) and trembling aspen (Populus tremuloides Michx.) in boreal planting environments in western Canada. Ecophysiological traits related to drought resistance and winter survival...

This two papers thesis explores the economics of hybrid poplar plantations as a potential bioethanol feedstock in Canada. The first paper (Chapter 2) is the stand-level analysis of the financial viability of producing hybrid poplar on private lands for both single-stem and coppice production...

Fall 2012
Variation in xylem structure and function has been extensively studied across different species with a wide taxonomic, geographical and ecological coverage. In contrast, our understanding of how xylem of a single species can adjust to different growing conditions remains limited. In this thesis,...

Forest level programming

This is a collection of the source codes I used in Remsoft (2013) to investigate different policy scenarios with two different forestry initial inventories.

Genetic variation of hydraulic and wood anatomical traits in hybrid poplar and trembling aspen
Download2011
Hacke, U.G., Schreiber, S.G., Hamann, A., Thomas, B.R.
•Intensive forestry systems and breeding programs often include either native aspen or hybrid poplar clones, and performance and trait evaluations are mostly made within these two groups. Here, we assessed how traits with potential adaptive value varied within and across these two plant groups....

Heterogeneous distribution of pectin epitopes and calcium in different pit types of four angiosperm species
Download2011
Intervessel pits act as safety valves that prevent the spread of xylem embolism. Pectin–calcium crosslinks within the pit membrane have been proposed to affect xylem vulnerability to cavitation. However, as the chemical composition of pit membranes is poorly understood, this hypothesis has not...

Luckert, Martin K., Armstrong, Glen W., Adamowicz, Wiktor L., Anderson, Jay A.
Previous studies suggest that management intensity zoning systems, such as the triad approach, could allow Canada’s forest industry to maintain or increase timber harvest levels while simultaneously reducing its environmental impact. In most such studies, the zones are exogenously specified. In...

Pit membrane structure is highly variable and accounts for a major resistance to water flow through tracheid pits in stems and roots of two boreal conifer species
Download2015
Schulte, P.J., Schoonmaker, A.L. , Hacke, U.G.
The flow of xylem sap in conifers is strongly dependent on the presence of a low resistance path through bordered pits, particularly through the pores present in the margo of the pit membrane. A computational fluid dynamics approach was taken, solving the Navier–Stokes equation for models based...

The role of water channel proteins in facilitating recovery of leaf hydraulic concutance from water stress in Populus trichocarpa
Download2014
Gas exchange is constrained by the whole-plant hydraulic conductance (Kplant). Leaves account for an important fraction of Kplant and may therefore represent a major determinant of plant productivity. Leaf hydraulic conductance (Kleaf) decreases with increasing water stress, which is due to xylem...
