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...

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...
