Pre-Commercial Thinning Increases Merchantability and Reduces Western Gall Rust Infections in Lodgepole Pine
DownloadFall 2023
Alberta’s forest industry is predicted to be impacted by a short to medium-term decline in timber supply. Intensive silviculture tools, such as pre-commercial thinning, have been shown to increase individual tree growth, shorten rotation lengths and improve stand merchantability in important...

Beyond mountain pine beetle: soil carbon storage a decade after tree mortality and the possible influence of soil fungi
DownloadSpring 2024
Mountain pine beetle (MPB; Dendroctonus ponderosae) disturbances, amplified by climate change, have led to extensive tree mortality and ecosystem succession in boreal forests across western Canada. Often following attack, former ectomycorrhizal (EM) pine stands in Alberta are replaced by...

Impact of Mountain Pine Beetle Attack on Water Balance of Lodgepole Pine Forests in Alberta
DownloadSpring 2013
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...

Observations of Sun-Induced Chlorophyll fluorescence (SIF), Photochemical Reflectance Index (PRI) and Chlorophyll:Carotenoid Index (CCI) during spring recovery in two evergreen conifers from the Boreal Forest.
DownloadFall 2022
Northern hemisphere evergreen forests assimilate a significant fraction of global atmospheric CO2. Conifers undergo winter-downregulated photosynthetic activity and spring-onset photosynthetic activation. Currently, increased temperatures are leading to shifts in photosynthetic phenology (early...

Molecular analysis of lodgepole and jack pine seedlings response to inoculation by mountain pine beetle fungal associate Grosmannia clavigera under well watered and water deficit
DownloadFall 2016
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...

Interactions Between Host Trees, Bacteria, and Fungi: Impacts on Mountain Pine Beetle (Dendroctonus ponderosae) Reproduction
DownloadFall 2012
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...

Mountain pine beetle outbreak and ectomycorrhizal feedback: the ecology of recovery in beetle killed forests
DownloadSpring 2014
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...

Spatial and temporal stand dynamics of mature lodgepole pine forests of the Canadian Rocky Mountains
DownloadFall 2015
In forest ecosystems, structure and species composition change over time as a function of ageing and minor disturbances and it is important to understand these changes for predicting forest productivity and habitat suitability for other plant and animal biota. Disturbances play a major role in...

Ecology of understory and below-ground communities in lodgepole pine forests under changing disturbance regimes
DownloadSpring 2013
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)...
