The mountain pine beetle (MPB; Dendroctonus ponderosae Hopkins), a major pine forest pest native to western North America, has extended its range north and eastward during an ongoing outbreak. Determining how the MPB has expanded its range to breach putative barriers, whether physical...
Could the lateral transfer of nutrients by outbreaking insects be a relevant landscape-level biogeochemical process?Download
The processes that transfer nutrients laterally over large distances are limited within ter-restrial ecosystems. Here, we present the hypothesis that outbreaking insects can sometimes transport consequential amounts of embodied nutrients over long distances, thereby connecting ecological...
Aftermath of mountain pine beetle outbreak in British Columbia: Stand dynamics, management response and ecosystem resilienceDownload
The mountain pine beetle (Dendroctonus ponderosae Hopkins) (MPB) has infested and killed millions of hectares of lodgepole pine (Pinus contorta var. latifolia Engelm) forests in British Columbia, Canada, over the past decade. It is now spreading out of its native range into the Canadian boreal...
Comparison of lodgepole and jack pine constitutive and induced resin chemistry: implications for range expansion by the mountain pine beetle, Dendroctonus ponderosae, (Coleoptera: Curculionidae)Download
The mountain pine beetle, Dendroctonus ponderosae, is a significant pest of lodgepole pine in British Columbia (BC), where it has recently reached an unprecedented outbreak level. Although it is native to western North America, the beetle can now be viewed as a native invasive because for the...
Unequal recombination and evolution of the mating-type (MAT) loci in the pathogenic fungus Grosmannia clavigera and relatives. G3: Genes, Genomes, GeneticsDownload
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....
Population Structure of Mountain Pine Beetle Symbiont Leptographium longiclavatum and the Implication on the Multipartite Beetle-Fungi RelationshipsDownload
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....
De novo genome sequence assembly of a filamentous fungus using Sanger, 454 and Illumina sequence dataDownload
Docking, Roderick T., Mardis, Elaine, Hamelin, Richard C., Jones, Steven J. M., Marra, Marco A., Seidel, Michael, Chan, Simon K., Breuil, Colette, Liao, Nancy Y., Birol, Inanc, Robertson, Gordon, Holt, Robert A., Platt, Darren, Bohlmann, Jörg, DiGuistini, Scott, Hirst, Martin
Sequencing-by-synthesis technologies can reduce the cost of generating de novo genome assemblies. We report a method for assembling draft genome sequences of eukaryotic organisms that integrates sequence information from different sources, and demonstrate its effectiveness by assembling an...
Influence of water deficit on the molecular responses of Pinus contorta × Pinus banksiana mature trees to infection by the mountain pine beetle fungal associate, Grosmannia clavigeraDownload
Conifers exhibit a number of constitutive and induced mechanisms to defend against attack by pests and pathogens such as mountain pine beetle (Dendroctonus ponderosae Hopkins) and their fungal associates. Ecological studies have demonstrated that stressed trees are more susceptible to attack by...
A species-diagnostic SNP panel for discriminating lodgepole pine, jack pine, and their interspecific hybridsDownload
Accurate stock identification is important for forest management, yet this can be a challenge for tree species that hybridize naturally. Species discriminating molecular markers provide a means to identify stock with high accuracy. In Canada, lodgepole pine (Pinus contorta Dougl. ex Loud. var....
Background The mountain pine beetle (Dendroctonus ponderosae) is a significant coniferous forest pest in western North America. It relies on aggregation pheromones to colonize hosts. Its three major pheromone components, trans-verbenol, exo-brevicomin, and frontalin, are thought to arise via...
