Assessing operational silviculture and modeling juvenile growth in Saskatchewan white spruce (Picea glauca (Moench) Voss) plantations
DownloadFall 2015
White spruce (Picea glauca (Moench) Voss) plantations are often established with mechanical site preparation and tending. These silvicultural treatments encourage plantation survival and can influence growth, composition, and yield. To assess operational silviculture and model managed stand...

Benthic Responses to Nitrogen and Phosphorus Deposition on Alpine Ponds in Banff National Park: A Replicated Whole-Ecosystem Experiment
DownloadFall 2012
Nitrogen (N) and Phosphorous (P) deposition at high elevations has increased by 40% over the last fifteen years, causing concern for the 3000+ alpine ponds in Banff National Park. A novel whole-ecosystem experiment was used to test for the effects of elevated N and P deposition on benthic...

Lighting, fire is the dominant natural disturbance of the western mixedwood boreal forest of North America. We quantified the independent effects of weather and forest composition oil lightning fire initiation (a detected and recorded fire start) patterns in Alberta, Canada, to demonstrate how...

Boreal trees can grow on saline sites – implications for reclamation success on saline soils
Download2015-03-04
Soils from oil sands mining can be affected by salts leached from tailings or overburden materials – resulting in saline soil conditions. As a result, re-establishment of forests on saline sites is an important goal on reclaimed oil sands mines. Forest vegetation is typically thought to be...

Breeding Bird Communities in Boreal Forest of Western Canada: Consequences of "Unmixing" the Mixedwoods
Download2000
Silvicultural practices following clearcutting in boreal forest may encourage the creation of monospecific, single-aged stands having less vegetation heterogeneity and diversity than original stands. We conducted point counts in central Saskatchewan, Canada, 1993–1995, in pure and mixedwood...

Characteristics of alpine plants and soils along an elevational gradient, Northern Selkirk Mountains, British Columbia
DownloadSpring 2019
Rates of climate change are accelerated at higher elevations, a pattern termed elevation-dependent warming (EDW). Consequently, the impacts of climate change on community patterning and soil development may be particularly evident in alpine environments. Alpine ecotone boundaries, such as...

Chemical similarity between historical and novel host plants promotes range and host expansion of the mountain pine beetle in a naïve host ecosystem
Download2013-01-01
Evenden, Maya, Shan, Bin, Ma, Cary, Najar, Ahmed, Erbilgin, Nadir, Whitehouse, Caroline
Host plant secondary chemistry can have cascading impacts on host and range expansion of herbivorous insect populations. We investigated the role of host secondary compounds on pheromone production by themountain pine beetle (Dendroctonus ponderosae) (MPB) and beetle attraction in response to a...

Fall 2014
Canada’s boreal forest is the breeding ground for some 288 species of resident and migratory birds. Approximately 65% of the species that are currently of highest conservation priority in the boreal region are associated with wetlands and riparian areas. Although estimates vary with scale and...

Conservation of forest-dwelling arthropod species: simultaneous management of many small and heterogeneous risks
Download2008
Volney, W.J.A., Langor, D. W., Jacobs, J. M., Work, T. T., Spence, J. R.
The Canadian insect fauna is too inadequately Understood to support well-informed assessments about its conservation status: however, the foregoing collection of synthetic papers illustrates potential threats front industrial forestry. Loss of forest species and dramatic changes in forest insect...
