The Role of Nutrient and Carbon Reserve Status of Aspen Seedlings in Root-Soil Interactions
DownloadFall 2015
The boreal forest is one of the largest forest ecosystems in the world, covering 14.7 million km2 globally. The Canadian boreal forest has a wealth of natural resources, including coal, timber, and oil; as resource exploration and exploitation has expanded, anthropogenic disturbance in the boreal...

Food availability and grizzly bear (Ursus arctos) selection of post-fire and thinned forests in the mountain national parks of Canada
DownloadFall 2018
Human-caused mortality and habitat loss have led to the extirpation of grizzly bears (Ursus arctos) across much of their North American range. Today, these factors continue to limit extant grizzly bear populations as productive habitats often occur in areas with elevated mortality risk creating...

Fall 2017
Legacy propagule banks of salvaged topsoils are excellent sources of plant propagules for reclamation of mine sites. However, prior studies show that less than 50% of species found in original propagule banks actually establish. We hypothesize that the expression of this legacy propagule bank is...

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...

Salt Affected Soils And Their Relationships With Plant Communities On Reclamation Well Sites
DownloadFall 2020
Salt affected soils are common around the world from natural causes or anthropogenic activities. Over 1030 million hectares of land worldwide are affected by salt or at risk of being affected. In Alberta, saline and sodic soils may occur with oil and gas production, increasing the risk of...

Resource allocation, water relations and crown architecture examined at the tree and stand-level in northern conifers
DownloadFall 2013
Variation in quantity of light has driven plants to employ many strategies in order to persist in high and low light. It is also a primary driver of lower branch mortality and crown recession. Fine roots and leaves are complimentary tissues representing belowground and aboveground resource...

Rhizosphere microbial response to predicted vegetation shifts and changes in rhizodeposition in boreal forest soils
DownloadFall 2018
The boreal forest is the single largest terrestrial store of carbon on Earth. In Canada’s boreal forest, approximately 23% of these carbon stocks are found in forest floors and 40% within mineral soils. The rhizosphere, soil under the direct influence of plant roots, is a hotspot for microbial...
