Adaptation of trembling aspen and hybrid poplars to frost and drought: implications for selection and movement of planting stock in western CanadaDownload
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...
Adaptation of white spruce populations to extreme climate events: implications for assisted migration practices in Western CanadaDownload
The movement of seed sources from south to north has been proposed as a tool to mitigate the effect of climate change on forest productivity and mortality. Southern provenances, coming from warmer regions are expected to better utilize the extended growing seasons expected under climate warming....
Assessing the vulnerability of rare plants using climate change velocity, habitat connectivity and dispersal abilityDownload
Climate change generally requires species to migrate northward or to higher elevation to maintain constant climate conditions, but migration requirement and migration capacity of individual species can vary greatly. Individual populations of species occupy different positions in the landscape...
A changing climate is the largest threat to forest productivity in western Canada and to the ability of forested landscapes to provide ecological and economic services, both now and in the future. As climate changes, locally adapted tree populations become mismatched with local conditions,...
Bioclimate envelope models are widely used to project potential species habitat under changing climate. Conceptually, these models are also well suited to match natural resource management practices to new climatic realities, for example by guiding species choice in reforestation programs....
Aspen is a widespread forest tree of high economic and ecological importance in western Canada. The species has also been subject to tree improvement efforts over the past two decades to increase productivity of the forested land base. Successful selection and breeding programs rely on both...
Genetic adaptation of aspen populations to spring risk environments: a novel remote sensing approachDownload
This study investigates geographic patterns of genetic variation in aspen spring phenology to understanding how tree population adapts to climatically risk environments. These finding suggest rules to guide seed transfer between regions. I use a classical common garden experiment to reveal...
Genetic variation in lodgepole pine and interior spruce: adaptation to climate and implications for seed transferDownload
This thesis investigates genetic variation of two commercially important conifers in western Canada, interior spruce and lodgepole pine. The goals were to quantify genetic diversity and geographic structure, to describe multitrait adaptation to local climates, and to use this information for the...
Guiding Douglas-fir seed selection in Europe under changing climates: bioclimatic envelope model predictions versus growth observed in provenance trialsDownload
Douglas-fir (Pseudotsuga menziesii (Mirbel) Franco) is one of the most ecologically and economically important tree species in both its native range in North America and in its introduced range in Europe. The aim of this research is to inform the European Douglas-fir reforestation strategy under...
Identifying historical climate-growth limitations of white spruce (Picea glauca) populations across North AmericaDownload
Climate change may cause reduced forest productivity and higher tree mortality due to water deficits that result from increased evapotranspiration. Such limitations may occur in some areas of the North American boreal forest, where precipitation is low and warming trends are high. This thesis...
