Schreiber, Stefan Georg

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...

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....

Barber, Quinn E.

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...

Gray, Laura

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,...

Mbogga, Michael Ssekaayi

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....

Ding, Chen

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...

Li, Haitao

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...

Liepe, Katharina J

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...

Isaac-Renton, Miriam G

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...

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...
