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....
Characterizing the physical and genetic structure of the lodgepole pine × jack pine hybrid zone: mosaic structure and differential introgressionDownload
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...
Forest die-off caused by mountain pine beetle (MPB; Dendroctonus ponderosa) is rapidly transforming western North American landscapes. The rapid and widespread death of lodgepole pine (Pinus contorta) will likely have cascading effects on biodiversity. One group particularly prone to such...
Ecology of understory and below-ground communities in lodgepole pine forests under changing disturbance regimesDownload
As climate changes and disturbance regimes shift, there is a need to better understand and anticipate potential impacts of both natural and anthropogenic disturbance agents on forest ecosystems. Lodgepole pine forests in western Canada are experiencing an unprecedented mountain pine beetle (MPB)...
In recent decades mountain pine beetle (MPB) has become an important natural disturbance agent in western Canada, thus the impact of this disturbance will likely be an important component affecting water resources in this region. Despite the widespread recognition of the potential changes, there...
Inconsistent growth response to fertilization and thinning of lodgepole pine in the Rocky Mountain Foothills is linked to site indexDownload
Fertilization of conifers often results in highly variable growth responses across sites which are difficult to predict. The goal of this study was to predict the growth response of lodgepole pine (Pinus contorta var. latifolia) crop trees to thinning and fertilization using basic site and foliar...
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...
Interactions Between Host Trees, Bacteria, and Fungi: Impacts on Mountain Pine Beetle (Dendroctonus ponderosae) ReproductionDownload
Warming winter trends due to climate change have allowed for a range expansion of the mountain pine beetle, and the beetle now threatens Canada’s economically and ecologically important jack pine forests. The beetle’s success in jack pine trees will depend upon successful colonization of the...
Molecular analysis of lodgepole and jack pine seedlings response to inoculation by mountain pine beetle fungal associate Grosmannia clavigera under well watered and water deficitDownload
To date mountain pine beetle (MPB) has affected more than 19 million ha. of pine forests in Canada. The primary species affected by the current outbreak has been lodgepole pine (Pinus contorta), however as MPB range expands eastward beyond its historical habitat, the bark beetle has encountered a...
Mountain pine beetle outbreak and ectomycorrhizal feedback: the ecology of recovery in beetle killed forestsDownload
The expansion of mountain pine beetle (Dendroctonus ponderosae; MPB) into naïve host ecosystems has been met by gaps in two key areas of research: (A) affects on the chemistry of forest soils, and (B) impacts on the regeneration of tree seedlings. To investigate linkages between both, we paired...
