Using a native plant-pathogen system as a model to investigate success of the invasive mountain pine beetle in jack pine
DownloadFall 2017
Tree-infesting organisms have recently expanded their ranges into many novel habitats where they will not only interact with new host tree species, but also with a myriad of other organisms that also share these hosts. Understanding the major factors and mechanisms that mediate...

Understanding the Role of Secondary Metabolites and Endophytic Fungi in White Spruce Defenses Against Eastern Spruce Budworm
DownloadFall 2023
As a boreal tree species, white spruce (Picea glauca Moench Voss) is under a constant threat by outbreaks of defoliators (foliar feeders) including eastern spruce budworm (Choristoneura fumiferana). Historically, applications of biological insecticides and silvicultural treatments have been used...

Soil fungi after pine beetle outbreak: Diagnosis of fungal community composition and treatment of outplanted seedlings with tailored soil inoculum
DownloadSpring 2019
Soil fungal communities play vital roles in boreal forests as key organisms that cycle nutrients, facilitate uptake of resources for mycorrhizal plants, and store carbon. Forest disturbances often result in shifts in soil fungal community composition, yet, it is unclear if these effects are...

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,...

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...

Fall 2012
Intra and inter-plant signalling was investigated in jack pine (Pinus banksiana) seedlings in response to jack pine budworm (Choristoneura pinus, Lepidoptera: Tortricidae) feeding. Defoliation was followed by a fungal inoculation by blue stain fungus (Grosmannia clavigera) to assess resistance....

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...

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...

Host Plant Chemistry Affects Fungal Interactions, Which Influence the Production of Volatile Fungal Metabolites
DownloadSpring 2019
Mountain pine beetle (MPB) has recently expanded its host range to novel jack pine forests in Alberta. Invasion success of MPB may depend on the outcome of interactions between its primary symbiotic fungus Grosmannia clavigera with other organisms sharing the same host. Among resources-sharing...

Ecology and life history of Coccophagus gossypariae (Hymenoptera: Aphelinidae), a parasitoid of Eriococcus spurius (Hemiptera: Eriococcidae)
DownloadSpring 2018
The American elm (Ulmus americana) is a valuable component of urban forests in Alberta. In many Alberta municipalities, the health of these trees is being heavily impacted by the invasive scale insect Eriococcus spurius (Hemiptera: Eriococcidae). Biological control of scales using hymenopteran...
