A comparison of coarse woody debris in post-harvest and post-fire island remnants a decade after disturbance in northern Alberta

Retention forestry is the practice of retaining forest structure within cut-blocks at harvest sites and is practiced widely throughout the world. Although retention practices are modelled on the propensity for fires to leave behind a variety of biological legacies or structural elements, the...

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...

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...
