Comparative genomics of the chitinase gene family in lodgepole and jack pines: contrasting responses to biotic threats and landscape level investigation of genetic differentiation.
Download2021-02-01
Peery, Rhiannon M., McAllister, Chandra H., Cullingham, Catherine I., Mahon, Elizabeth L., Arango-Velez, Adriana, Cooke, Janice E. K.
The sister species, lodgepole pine (Pinus contorta var. latifolia Engelm.) and jack pine (Pinus banksiana Lamb), face pressures from a multitude of biotic agents, including mountain pine beetle (Dendroctonus ponderosae Hopkins, 1902) and their pathogenic fungal associates (e.g., Grosmannia...

Linking genotype to phenotype to identify genetic variation relating to host susceptibility in the mountain pine beetle system
Download2020-01-01
Cullingham, Catherine I., Peery, Rhiannon M., Fortier, Colleen E., Mahon, Elizabeth L., Cooke, Janice E. K., Coltman, David W.
Identifying genetic variants responsible for phenotypic variation under selective pressure has the potential to enable productive gains in natural resource conservation and management. Despite this potential, identifying adaptive candidate loci is not trivial, and linking genotype to phenotype is...

Repurposing population genetics data to discern genomic architecture: A case study of linkage cohort detection in mountain pine beetle (Dendroctonus ponderosae)
Download2019-01-01
Trevoy, Stephen A.L., Janes, Jasmine K., Muirhead, Kevin, Sperling, Felix A. H.
Genetic surveys of the population structure of species can be used as resources for exploring their genomic architecture. By adjusting filtering assumptions, genomewide single-nucleotide polymorphism (SNP) datasets can be reused to give new insights into the genetic basis of divergence and...

Fine-scale genetic diversity and relatedness in fungi associated with the mountain pine beetle
Download2019-01-01
Tsui, Clement K. M., Beauseigle, Stephanie, Ojeda Alayon, Dario I., Rice, Adrianne V., Cooke, Janice E. K., Sperling, Felix A. H., Roe, Amanda D., Hamelin, Richard C.
The mountain pine beetle (MPB; Dendroctonus ponderosae Hopkins, 1902) forms beneficial symbiotic associations with fungi. Here we explored the fine-scale spatial genetic structure of three of those fungi using single nucleotide polymorphism. We found that single mated pairs of beetles carry not...

The contribution of genetics and genomics to understanding the ecology of the mountain pine beetle system
Download2019-01-01
Cullingham, Catherine I., Janes, Jasmine K., Hamelin, Richard C., James, Patrick M.A., Murray, Brent W., Sperling, Felix A.H.
Environmental change is altering forest insect dynamics worldwide. As these systems change, they pose significant ecological, social, and economic risk through, for example, the loss of valuable habitat, green space, and timber. Our understanding of such systems is often limited by the complexity...

Wittische, Julian, Janes, Jasmine K., James, Patrick M. A.
The current mountain pine beetle (MPB; Dendroctonus ponderosae Hopkins, 1902) outbreak has reached more than 25 million hectares of forests in North America, affecting pine species throughout the region and substantially changing landscapes. However, landscape features that enhance or limit...

Selection of the sex-linked Inhibitor of Apoptosis in Mountain Pine Beetle (Dendroctonus ponderosae) driven by enhanced expression during early overwintering

Horianopoulos, Linda C., Boone, Celia K., Samarasekera, Gayathri, Kandola, Gurkirat K., Murray, Brent W.
The mountain pine beetle (Dendroctonus ponderosae) is an insect native to western North America; however, its geographical range has recently expanded north in BC and east into Alberta. To understand the population structure in the areas of expansion, 16 gene‐linked microsatellites were screened...

Polygamy and an absence of fine-scale structure in Dendroctonus ponderosae (Hopk) (Coleoptera: Curcilionidae) confirmed using molecular markers

Janes, Jasmine K., Roe, Amanda D., Rice, A. V., Gorrell, Jamieson C., Coltman, D. W., Langor, David W., Sperling, Felix A.
An understanding of mating systems and fine-scale spatial genetic structure is required to effectively manage forest pest species such as Dendroctonus ponderosae (mountain pine beetle). Here we used genome-wide single-nucleotide polymorphisms to assess the fine-scale genetic structure and mating...

Adaptive and neutral markers both show continent-wide population structure of mountain pine beetle (Dendroctonus ponderosae)
Download2016-01-01
Sperling, Felix A. H., Murray, Brent W., Batista, Philip D., Janes, Jasmine K., Boone, Celia K.
Assessments of population genetic structure and demographic history have traditionally been based on neutral markers while explicitly excluding adaptive markers. In this study, we compared the utility of putatively adaptive and neutral single-nucleotide polymorphisms (SNPs) for inferring mountain...

Population Structure of Mountain Pine Beetle Symbiont Leptographium longiclavatum and the Implication on the Multipartite Beetle-Fungi Relationships

Roe, Amanda D., Farfan, Lina, Cooke, Janice E. K., Hamelin, Richard C., El-Kassaby, Yousry A., Rice, Adrianne V., Tsui, Clement K.
Over 18 million ha of forests have been destroyed in the past decade in Canada by the mountain pine beetle (MPB) and its fungal symbionts. Understanding their population dynamics is critical to improving modeling of beetle epidemics and providing potential clues to predict population expansion....
