The Effect of Water Limitation on Volatile Emission, Tree Defense Response, and Brood Success of Dendroctonus ponderosae in Two Pine Hosts, Lodgepole, and Jack Pine
Download2016
Lusebrink, Inka, Erbilgin, Nadir, Evenden, Maya L.
The mountain pine beetle (MPB; Dendroctonus ponderosae) has recently expanded its range from lodgepole pine forest into the lodgepole × jack pine hybrid zone in central Alberta, within which it has attacked pure jack pine. This study tested the effects of water limitation on tree defense response...

The genetic signature of rapid range expansions: How dispersal, growth and invasion speed impact heterozygosity and allele surfing

Lewis, Mark A. , Coltman, David W. , Goodsman, Devin W., Cooke, Barry
As researchers collect spatiotemporal population and genetic data in tandem, models that connect demography and dispersal to genetics are increasingly relevant. The dominant spatiotemporal model of invasion genetics is the stepping-stone model which represents a gradual range expansion in which...

The lodgepole x jack pine hybrid zone in Alberta, Canada: A stepping stone for the mountain pine beetle on its journey east across the Boreal forest?

Evenden, Maya L., Erbilgin, Nadir, Lusebrink, Inka
Historical data show that outbreaks of the tree killing mountain pine beetle are often preceded by periods of drought. Global climate change impacts drought frequency and severity and is implicated in the range expansion of the mountain pine beetle into formerly unsuitable habitats. Its expanded...

Dispersal can push population density below strong Allee thresholds ensuring the demise of small founding populations. As a result, for isolated populations of dispersing organisms, the minimum founding population size that enables establishment can be quite different from the Allee threshold. 2....

The mountain pine beetle (MPB) is among the most destructive eruptive forest pests in North America. A recent increase in the frequency and severity of outbreaks, combined with an eastward range expansion towards untouched boreal pine forests, has spurred a great interest by government, industry...

Chiu, Christine C., Bohlmann, Jeorg, Keeling, Christopher I.
The mountain pine beetle (Dendroctonus ponderosae; MPB) is an eruptive bark beetle species afecting pine forests of western North America. MPB are exposed to volatile monoterpenes, which are important host defense chemicals. We assessed the toxicity of the ten most abundant monoterpenes of...

Transcriptome resources and functional characterization of monoterpene synthases for two host species of the mountain pine beetle, lodgepole pine (Pinus contorta) and jack pine (Pinus banksiana)

Hall, Dawn E., Arango-Velez, Adriana, Dullat, Harpreet K., Keeling, Christopher I., Breuil, Colette, Liao, Nancy Y., Henderson, Hannah, Bohlmann, Jörg, Cooke, Janice E. K., Quesada, Alfonso L., Jones, Steven J. M., Chan, Simon K., Jancsik, Sharon, Docking, Roderick T., Li, Maria, Yuen, Macaire M. S.
Background The mountain pine beetle (MPB, Dendroctonus ponderosae) epidemic has affected lodgepole pine (Pinus contorta) across an area of more than 18 million hectares of pine forests in western Canada, and is a threat to the boreal jack pine (Pinus banksiana) forest. Defence of pines against...

TRIA-Net: 10 years of collaborative research on turning risk into action for the mountain pine beetle epidemic

James, Patrick M.A., Huber, Dezene P.W.
Forest insects are showing increasing intensity of outbreaks and expanded ranges, and this has become a major challenge for forest managers. An understanding of these systems often depends upon detailed examination of complex interactions involving multiple organisms. In 2013, a team of...

Unequal recombination and evolution of the mating-type (MAT) loci in the pathogenic fungus Grosmannia clavigera and relatives. G3: Genes, Genomes, Genetics

Hamelin, Richard C., Tsui, Clement K.M., Bohlmann, Jörg, DiGuistini, Scott, Dhillon, Braham, Feau, Nicolas, Wang, Ye
Sexual reproduction in fungi is regulated by the mating-type (MAT) locus where recombination is suppressed. We investigated the evolution of MAT loci in eight fungal species belonging to Grosmannia and Ophiostoma (Sordariomycetes, Ascomycota) that include conifer pathogens and beetle symbionts....

Water-deficit and fungal infection can differentially affect the production of different classes of defense compounds in two host pines of mountain pine beetle

Erbilgin, Nadir, Cale, Jonathan, Lusebrink, Inka, Najar, Ahmed, Klutsch, Jennifer, Sherwood, Patrick, Bonello, Pierluigi, Evenden, Maya
Bark beetles are important agents of tree mortality in conifer forests and their interaction with trees is influenced by host defense chemicals, such as monoterpenes and phenolics. Since mountain pine beetle (Dendroctonus ponderosae Hopkins) has expanded its host range from lodgepole pine (Pinus...
