Modeling the impacts of recent climate change on ecosystem productivity across North America
DownloadFall 2015
There is evidence of warming and changes in precipitation over recent decades in most regions of North America (NA) that are affecting ecosystem productivity. The impacts of these changes on land-atmosphere carbon exchange over a wide range of biomes are spatially heterogeneous and uncertain. In...

Identifying historical climate-growth limitations of white spruce (Picea glauca) populations across North America
DownloadSpring 2021
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...

Fall 2015
Given high levels of human disturbance and projected rates of climate change, many species will be unable to keep pace with their shifting climatic ranges and thus face increased risk of extinction. This research investigated the use of assisted migrations for two rare and range-restricted plant...

Wildfires and climate change: their effects on moose (Alces alces) and white-tailed deer (Odocoileus virginianus) winter habitat in the boreal mixedwoods of Alberta, Canada
DownloadFall 2021
Understanding how species respond to wildfires and climate change is fundamental for land use management and biodiversity conservation. Wildfires provide generalist ungulates, such as moose (Alces alces) and white-tailed deer (Odocoileus virginianus), with high quantity and quality of winter...

Influence of wildfire and permafrost thaw on dissolved organic carbon (DOC) in northern peatlands; implications for lability and downstream transport
DownloadFall 2017
Peatlands in Canada’s western boreal forest are a major source of dissolved organic carbon (DOC) to downstream ecosystems, where DOC regulates carbon cycling, and can affect ecosystem productivity and habitat quality. Subarctic ecosystems are becoming increasingly vulnerable to the effects of...

Soil Organic Carbon Content and Stability, and Greenhouse Gas Emissions in Three Agroforestry Systems in Central Alberta, Canada
DownloadFall 2016
Western Canada’s prairie region is extensively cultivated for agricultural production, which is a large source of greenhouse gas (GHG) emissions. Agroforestry systems are common land uses across Canada, which integrate trees into the agricultural landscape and could play a substantial role in...

Climate change, adaptive capacity and new land innovations implemented by local farmers and indigenous people in Puerto Carreno, Colombia
DownloadFall 2012
A case study research was conducted in the city of Puerto Carreño, Colombia to assess adaptive capacity for the Farmers’ community and indigenous people to face climate change. Some of these inhabitants understand these changes in the weather as natural processes, others as climate change. The...

Mountain pine beetle outbreak and ectomycorrhizal feedback: the ecology of recovery in beetle killed forests
DownloadSpring 2014
The expansion of mountain pine beetle (Dendroctonus ponderosae; MPB) into naïve host ecosystems has been met by gaps in two key areas of research: (A) affects on the chemistry of forest soils, and (B) impacts on the regeneration of tree seedlings. To investigate linkages between both, we paired...

Fall 2010
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....

Guiding Douglas-fir seed selection in Europe under changing climates: bioclimatic envelope model predictions versus growth observed in provenance trials
DownloadFall 2013
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...
