In north-central Alberta, lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia) and jack pine (Pinus banksiana Lamb.) form a mosaic hybrid zone, the spatial extent of which remains poorly defined. We sought to refine the genetic and geographic distribution of this hybrid zone in western...

Effect of water stress and plant defense stimulation on monoterpene emission from a historical and a new pine host of the mountain pine beetle

Cooke, Janice E. K., Blanchet, F. Guillaume, Lusebrink, Inka, Erbilgin, Nadir, Evenden, Maya L.
The mountain pine beetle (Dendroctonus ponderosae, MPB) has killed millions of lodgepole pine (Pinus contorta) trees in Western Canada and recent range expansion has resulted in attack of jack pine (Pinus banksiana) in Alberta. Establishment of MPB in the Boreal forest will require use of jack...

Characterizing the physical and genetic structure of the lodgepole pine × jack pine hybrid zone: mosaic structure and differential introgression

Coltman, David W., James, Patrick M. A., Cullingham,Catherine I., Cooke, Janice E. K.
Understanding the physical and genetic structure of hybrid zones can illuminate factors affecting their formation and stability. In north-central Alberta, lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia) and jack pine (Pinus banksiana Lamb) form a complex and poorly defined hybrid...

Spatial community structure of mountain pine beetle fungal symbionts across a latitudinal gradient

Roe, Amanada D., James, Patrick M. A., Cooke, Janice E. K., Sperling, Felix A. H., Rice, Adrianne V.
Symbiont redundancy in obligate insect–fungal systems is thought to buffer the insect host against symbiont loss and to extend the environmental conditions under which the insect can persist. The mountain pine beetle is associated with at least three well-known and putatively obligate...

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....

Gene discovery for enzymes involved in limonene modification or utilization by the mountain pine beetle-associated pathogen Grosmannia clavigera

Lah, Ljerka, Wang, Ye, Breuil, Colette, Madilao, Lina, Bohlmann, Joerg, Lim, Lynette
To successfully colonize and eventually kill pine trees, Grosmannia clavigera (Gs cryptic species), the main fungal pathogen associated with the mountain pine beetle (Dendroctonus ponderosae), has developed multiple mechanisms to overcome host tree chemical defenses, of which terpenoids are a...

Consequences of distributional asymmetry in a warming environment: Invasion of novel forests by the mountain pine beetle
Download2017
Burke, Jordan Lewis, Bohlmann, Joerg, Carroll, Allan L.
The range of many Holarctic forest insects does not comprise the entire range of their hosts, as they are often limited to more southern latitudes by the adverse effects of cold temperatures. Global climate warming has led to the increased potential for forest insects to invade novel habitats of...

Comparative genomics of the chitinase gene family in lodgepole and jack pines: contrasting responses to biotic threats and landscape level investigation of genetic differentiation.

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...

Functions of mountain pine beetle cytochromes P450 CYP6DJ1, CYP6BW1 and CYP6BW3 in the oxidation of pine monoterpenes and diterpene resin acids

Chiu, Christine C., Keeling, Christopher I., Henderson, Hannah M., Bohlmann, Joerg
The mountain pine beetle (MPB; Dendroctonus ponderosae) is a forest insect pest that attacks several different pine (Pinus) species in its native range of distribution in western North America. MPB are exposed for most of their life cycle to the chemical defenses of their hosts. These defenses...

A species-diagnostic SNP panel for discriminating lodgepole pine, jack pine, and their interspecific hybrids

Dang, S. , Cullingham, Catherine I. , Cooke, Janice E. K., Coltman, David W.
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....
