A range-wide common garden experiment of white spruce indicates population differentiation in drought tolerance traits
DownloadFall 2019
In western regions of the Canadian boreal forest, mean annual temperature has increased by 1.5 to 2.5 °C, significantly exceeding the mean global temperature increase. Climate conditions have also become drier and together these climate trends have induced widespread growth reductions, dieback...

Adaptation of white spruce populations to extreme climate events: implications for assisted migration practices in Western Canada
DownloadSpring 2019
The movement of seed sources from south to north has been proposed as a tool to mitigate the effect of climate change on forest productivity and mortality. Southern provenances, coming from warmer regions are expected to better utilize the extended growing seasons expected under climate warming....

Application of LiDAR DEM Metrics to Estimate Road-stream Sediment Connectivity in Alberta Eastslopes Salmonid Habitats
DownloadFall 2019
In forest lands, through surface erosion and stream fragmentation, roads can be an important source of sediment generation and supply to streams. Disturbances on salmonid habitats and downstream values such as drinking water are considered to be one of the major concerns of road sediment...

Application of manure from cattle fed with different diets affects soil properties and greenhouse gas emissions
DownloadSpring 2019
Cattle production contributes the largest portion of livestock agricultural greenhouse gas (GHG) emissions in Canada mostly in the form of methane (CH4). Efforts to reduce CH4 emissions have led to modification of diet composition for livestock, resulting in a corresponding change in manure...

Spring 2019
Trembling aspen (Populus tremuloides Michx.) is a common species in Canadian boreal forests. As a shade intolerant and dynamic species (i.e., stand density and structure change over time), it naturally regenerates by root suckering and grows rapidly. Aspen has a short life compared to spruce or...

Burn severity and fire history in the northwestern Canadian boreal forest: drivers and ecological outcomes
DownloadSpring 2019
Wildfire is the dominant stand-renewing disturbance in the northwestern Canadian boreal forest. Fires burn extensive areas in Canada, disturbing an average of 1.96 Mha yr−1, primarily in the boreal zone. Fires generally occur every ~30 – > 200 years in this region, due in part to a lack of fuel...

Changes in soil fungal communities following logging and salvage logging disturbances decrease lodgepole pine (Pinus contorta var. latifolia) seedling performance
DownloadSpring 2019
Disturbances are frequent events across the Canadian boreal forests and can affect both below and above ground ecosystem processes at various temporal and spatial scales. We have limited understanding of how changes in the below ground fungal communities affect above ground plant communities....

Climate data and climate-based seed zones for Mexico: guiding reforestation under observed and projected climate change
DownloadFall 2019
Seed zones for forest tree species have been used for decades to guide seed movement in reforestation programs, ensuring that seedlings are well adapted to their planting environments. Seeds may be collected and planted anywhere within a zone, but not across zone boundaries. The zones are...

Drought and defoliation-induced alterations to the structure and function of the vascular tissue in trees
DownloadSpring 2019
Observations of tree dieback and mortality from climate change-induced drought has been documented across the world, however the mechanisms of tree mortality are not fully understood. Infestations of insect pests may also contribute to the process of drought-induced dieback. Tree physiological...
