Large-scale insect outbreak homogenizes the spatial structure of ectomycorrhizal fungal communities
Download2019-01-01
Ectomycorrhizal fungi (plant symbionts) are diverse and exist within spatially variable communities that play fundamental roles in the functioning of terrestrial ecosystems. However, the underlying ecological mechanisms that maintain and regulate the spatial structuring of ectomycorrhizal fungal...

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...

Morphological variation associated with dispersal capacity in a treekilling bark beetle Dendroctonus ponderosae Hopkins
Download2018-01-01
Shegelski, Victor A., Evenden, Maya L., Sperling, Felix AH
Intrinsic factors influencing the dispersal of insect pests during outbreaks are poorly understood, yet these factors need to be quantified to parameterize dispersal in models that predict population spread. The present study related wing and body morphology of female mountain pine beetles...

Fall 2020
Dispersal by flight is a complex life history phase in many insects that is essential to gene flow and range expansion. Many elements contribute to realized dispersal, including biotic and abiotic environmental conditions, as well as intrinsic factors such as morphology, physiology and behavior....

Multilocus species identification and fungal DNA barcoding: insights from blue stain fungal symbionts of the mountain pine beetle
Download2020-01-08
Roe, Amanda, Rice, Adrianne, Bromilow, Sean, Cooke, Janice, Sperling, Felix
There is strong community-wide interest in applying molecular techniques to fungal species delimitation and identification, but selection of a standardized region or regions of the genome has not been finalized. A single marker, the ribosomal DNA internal transcribed spacer region, has frequently...

Nitrogen and Ergosterol Concentrations Varied in Live Jack Pine Phloem Following Inoculations With Fungal Associates of Mountain Pine Beetle
Download2020-01-01
Guevara-Rozo, Sydne, Hussain, Altaf, Cale, Jonathan A., Klutsch, Jennifer G., Rajabzadeh, Rahmatollah, Erbilgin, Nadir
Bark beetles form symbiotic associations with multiple species of fungi that supplement their metabolic needs. However, the relative contributions of each symbiont to the nutrition of bark beetles have been largely unexplored. Thus, we evaluated the ability of three fungal symbionts of mountain...

Optimization of semiochemical monitoring for pea leaf weevil, Sitona lineatus (Coleoptera: Curculionidae), in the Prairie Provinces
DownloadFall 2017
The pea leaf weevil, Sitona lineatus Linnaeus (Coleoptera: Curculionidae) is an invasive pest of increasing concern to pulse producers in the Canadian Prairie Provinces. Pea leaf weevil larvae cause damage to field pea (Pisum sativum) and faba bean (Vicia faba) crops by feeding on root nodules...

Seasonal shifts in accumulation of glycerol biosynthetic gene transcripts in mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae), larvae
Download2017
Fraser, Jordie D., Bonnett, Tiffany R., Keeling, Christopher I., Huber, Dezene P.W.
Winter mortality is a major factor regulating population size of the mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae). Glycerol is the major cryoprotectant in this freeze intolerant insect. We report findings from a gene expression study on an overwintering...

Short- and long-term cold storage of jack pine bolts is associated with higher concentrations of monoterpenes and nutrients
Download2019-01-01
Guevara-Rozo, Sydne, Classens, Gail, Hussain, Altaf, Erbilgin, Nadir
Studies with conifer-infesting bark beetles commonly use bolts cut from trees 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...

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...
