Characterizing the changes in host tree chemistry after cutting and revisiting the nutritional role of fungi in the novel mountain pine beetle host jack pine
DownloadFall 2018
Studies with conifer-infesting bark beetles commonly use tree bolts to evaluate the effects of host tree quality on various aspects of insect biology. Yet, whether host quality changes between live trees and bolts cut from these trees has not been assessed. Particularly, changes in concentrations...

Chemotypic variations of lodgepole pine affect mountain pine beetle behaviour and growth of its symbiotic fungus
DownloadSpring 2020
Plants generally show large chemotypic variations in susceptibility to phytophagous insects and pathogens. Plant chemical defenses, or secondary compounds, are important components of plant resistance to pest organisms. Among plants, coniferous trees produce complex oleoresins that contain toxic...

Effects of Changing Climate on Interactions Among Mountain Pine Beetle, Host Tree, and Microorganisms
DownloadFall 2024
Environmental factors such as elevated levels of CO2 and O3 are increasingly affecting forest trees globally. Changes in climate have led to shifts in the geographic distribution of pests and pathogens associated with forests, with predictions of more native and invasive pests in the future. In...

Legacy Effects of Mountain Pine Beetle Outbreak: Defense, Growth and Survival of Residual Lodgepole Pine Trees in Alberta
DownloadFall 2019
Periodic mountain pine beetle outbreaks have affected millions of hectares of lodgepole pine forests in western North America. Within these stands often some pine trees remain alive. In addition to causing direct pine mortality, outbreaks also have short- and long-term legacy effects on both...

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...
