Goodsman, Devin W., Koch, Daniel, Whitehouse, Caroline, Evenden, Maya L., Cooke, Barry J., Lewis, Mark A.
We investigate the inside dynamics of solutions to integrodifference equations to understand the genetic consequences of a population with nonoverlapping generations undergoing range expansion. To obtain the inside dynamics, we decompose the solution into neutral genetic components. The inside...

Breaking the wall of silence of trees Mining metabolomics to describe hybridization and predict performance in the Populus – Sphaerulina musiva pathosystem
DownloadFall 2017
Stem canker diseases in poplars caused by the fungal pathogen Sphaerulina musiva Peck. remain some of the least understood forest diseases despite causing considerable damage, particularly in hybrid poplar plantations. S. musiva is endemic to eastern Canada in provinces including the Maritimes,...

Chemical similarity between historical and novel host plants promotes range and host expansion of the mountain pine beetle in a naïve host ecosystem
Download2013-01-01
Evenden, Maya, Shan, Bin, Ma, Cary, Najar, Ahmed, Erbilgin, Nadir, Whitehouse, Caroline
Host plant secondary chemistry can have cascading impacts on host and range expansion of herbivorous insect populations. We investigated the role of host secondary compounds on pheromone production by themountain pine beetle (Dendroctonus ponderosae) (MPB) and beetle attraction in response to a...

Diverting Resources to Turn on Resistance: Influences of Biotic and Abiotic Stresses on Aspen Seedlings
DownloadFall 2012
The interactions between biotic and abiotic stresses and their influence on plant reserves in non-photosynthetic tissues (i.e., roots and stems) and the role of plant reserves in tree defenses are poorly understood. Aspen seedlings grown under different conditions (light, fertilizer) were grouped...

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...

Rapid monoterpene induction promotes the susceptibility of a novel host pine to mountain pine beetle colonization but not to beetle-vectored fungi
Download2017-12-01
Cale, Jonathan A, Muskens, Marlena, Najar, Ahmed, Ishangulyyvena, Guncha, Hussain, Altaf, Kanekar, Sanat S, Klutsch, Jennifer G, Taft, Spencer, Erbilgin, Nadir
Chemical induction can drive tree susceptibility to and host range expansions of attacking insects and fungi. Recently, mountain pine beetle (Dendroctonus ponderosae Hopkins; MPB) has expanded its host range from its historic host lodgepole pine (Pinus contorta var. latifolia Douglas ex Loudon)...

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...

Spatial characteristics of volatile communication and the role of soil resources in pine defenses
DownloadFall 2019
Recent unprecedented climate change has increased the frequency and severity of tree-killing Dendroctonus bark beetles (Coleoptera: Curculionidae, Scolytinae). Understanding factors and mechanisms influencing host plant-bark beetle interactions at a landscape level such as plant defenses, edaphic...

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...
