Biogeochemical Cycling and Microbial Communities in Native Grasslands:Responses to Climate Change and Defoliation
DownloadSpring 2010
Ongoing climate change has emerged as a major scientific challenge in the current century. Grassland ecosystems are considered net carbon (C) sinks to mitigate climate change. However, they are in turn, influenced by climate change and management practices, providing feedback to climate change...

Climate Change Impacts on Logging Operations and Winter Roads: Costs and Mitigation Strategies
DownloadFall 2020
Many cold regions of North America rely on frozen ground for forestry operations to reduce environmental impacts, decrease costs, and access difficult areas surrounded by wet soils. Climate change may influence forestry operations by reducing winter access in those cold regions. In this thesis, I...

Playing with fire: Dendroctonus ponderosae (mountain pine beetles) in post-burn lodgepole pine forests
DownloadSpring 2015
Dendroctonus ponderosae, an aggressive tree-killing bark beetle, is one of the most significant insects in the coniferous forests of western North America. Although D. ponderosae is restricted to weakened host trees at low-density populations, fire can suddenly increase the number of suitable,...

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...
