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...

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...

Spatial characteristics of volatile communication in lodgepole pine trees: Evidence of kin recognition and intra-species support
Download2019-11-01
Hussain, Altaf, Rodriquez-Ramos, Jean C., Erbilgin, Nadir
Plant interactions using volatile organic compounds, particularly in the context of kin recognition have received considerable attention in recent years, but several discrepancies and conflicting results have restricted our understanding. We propose that some of these discrepancies in literature...

Testing for trade-offs between flight and reproduction in the mountain pine beetle (Coleoptera: Curculionidae) on two pine hosts
Download2019-01-01
Wijerathna, Asha, Whitehouse, Caroline, Proctor, Heather, Evenden, Maya
Mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae) adults fly to disperse before host colonization. The effect of flight on reproduction was tested by comparing the number and quality of offspring from beetles flown on flight mills to that of unflown...

Where did mountain pine beetle populations in Jasper Park come from? Tracking beetles with genetics
Download2018-01-01
Trevoy, Stephen AL, Janes, Jasmine K, Sperling, Felix AH
The invasion of mountain pine beetle (Dendroctonus ponderosae Hopk.) into Alberta has been an ongoing concern for forest management. The beetle’s recent appearance and spread in Jasper National Park now poses ecological and economic threats to forestry in regions to the east. By applying recent...
