Growth of understory spruce following mountain pine beetle attack and recalibration and validation of the Mixedwood Growth Model for black spruce
DownloadFall 2018
Effective forest management requires reliable growth and yield models and adequate information on changes in the forest resulting from climate change, insect outbreak and competition from neighboring trees. Growth responses of white spruce (Picea glauca (Moench) Voss) and black spruce (Picea...

Interactions Between Host Trees, Bacteria, and Fungi: Impacts on Mountain Pine Beetle (Dendroctonus ponderosae) Reproduction
DownloadFall 2012
Warming winter trends due to climate change have allowed for a range expansion of the mountain pine beetle, and the beetle now threatens Canada’s economically and ecologically important jack pine forests. The beetle’s success in jack pine trees will depend upon successful colonization of the...

Molecular analysis of lodgepole and jack pine seedlings response to inoculation by mountain pine beetle fungal associate Grosmannia clavigera under well watered and water deficit
DownloadFall 2016
To date mountain pine beetle (MPB) has affected more than 19 million ha. of pine forests in Canada. The primary species affected by the current outbreak has been lodgepole pine (Pinus contorta), however as MPB range expands eastward beyond its historical habitat, the bark beetle has encountered a...

Observations of Sun-Induced Chlorophyll fluorescence (SIF), Photochemical Reflectance Index (PRI) and Chlorophyll:Carotenoid Index (CCI) during spring recovery in two evergreen conifers from the Boreal Forest.
DownloadFall 2022
Northern hemisphere evergreen forests assimilate a significant fraction of global atmospheric CO2. Conifers undergo winter-downregulated photosynthetic activity and spring-onset photosynthetic activation. Currently, increased temperatures are leading to shifts in photosynthetic phenology (early...

PLANT FATTY ACIDS INFLUENCE BROOD DEVELOPMENT OF MOUNTAIN PINE BEETLE AND GROWTH OF ITS SYMBIOTIC FUNGUS: IMPLICATIONS TO HOST-RANGE EXPANSION OF AN HERBIVOROUS INSECT
DownloadSpring 2015
Nutritional composition of plants can affect the performance of insect herbivores and their associated microbial symbionts. Mountain pine beetle (Dendroctonus ponderosae) is an important bark beetle species that colonizes many species of Pinus within its historical range and encounter host...

Client sexual advances may be a common occurrence in therapy, yet there is little information available with strategies for managing them. In hope of initiating a dialogue, five female therapists’ experiences were examined for possible insights. Informal semi-structured interviews provided data...

Ecology of understory and below-ground communities in lodgepole pine forests under changing disturbance regimes
DownloadSpring 2013
As climate changes and disturbance regimes shift, there is a need to better understand and anticipate potential impacts of both natural and anthropogenic disturbance agents on forest ecosystems. Lodgepole pine forests in western Canada are experiencing an unprecedented mountain pine beetle (MPB)...

Variations in jack pine (Pinus banksiana) monoterpene composition and subsequent effects on pheromone production by mountain pine beetle (Dendroctonus ponderosae)
DownloadSpring 2015
The secondary compounds of pines (Pinus) can strongly affect the physiology, ecology and behaviour of bark beetles (Coleoptera: Curculionidae, Scolytinae) that feed on host sub-cortical tissues. Jack pine (Pinus banksiana) has a wide distribution range in North America and thus variations in its...

Induced monoterpene responses in jack pine: defence against jack pine budworm and a fungal associate of the mountain pine beetle
DownloadFall 2010
My thesis research investigated monoterpene responses in jack pine (Pinus banksiana Lamb.) to different agents to better understand how these responses may influence the spread of the mountain pine beetle (Dendroctonus ponderosae Hopkins; MPB) in the boreal forest. The results support that...
