The impact of recreational activities on an alpine vascular plant community in the Canadian Rockies
DownloadFall 2010
Alpine tundra is notorious for its fragility and slow recovery following disturbance. Tourism is increasing in alpine areas, creating the need to improve our understanding of the impacts of recreation in these ecosystems. This study examined the impacts of hiking and off-highway vehicle use on...

The Importance and Influence of the Human Dimensions in Grizzly Bear (Ursus arctos) Conservation
DownloadFall 2018
Conservation practitioners increasingly recognize the importance and influence of the social context in conservation outcomes. From local stories to newsprint articles, the language we use, the stories we tell, and the interactions we have with wildlife species can influence human relationships...

The Increasing Prevalence of Smaller Fish in Highly Exploited Fisheries: Concerns, Diagnosis and Management Solutions.
DownloadSpring 2010
A decline in the size of fish within a population is concerning. Large-sized fish are ecologically important and valued for social and economic reasons. Following widespread collapses from angling overharvest, the densities of Walleyes Sander vitreus in Alberta’s lakes increased rapidly with...

Spring 2011
Quantification of the effects of residual forest structure on the understory light environment is needed to guide silvicultural strategies that facilitate regeneration. In this study I measured understory light using various methods in a dry, uneven-aged mixed conifer forest in British Columbia,...

The influence of soil reconstruction materials and targeted fertilization on the regeneration dynamics in boreal upland forest reclamation
DownloadFall 2019
Soil is an essential component supporting the growth and maintenance of terrestrial ecosystems such as forests, providing anchorage, water, and nutrients. In Canada’s boreal forest landscape, surface soils can differ widely in their chemical and physical conditions, ranging from coarse to fine...

The influences of fuel moisture and diameter on pyrogenic carbon production in fine woody debris from three boreal tree species under simulated surface fire conditions.
DownloadSpring 2020
Wildland fires burn millions of hectares annually, releasing a significant amount of carbon into the atmosphere. Wildland fires also produce pyrogenic carbon – thermally-altered biomass that is highly resistant to decay – which accumulates in fire-affected ecosystems over time. Large wildfires,...

The Introduction of Cipangopaludina chinensis and Trophic Effects of Sympatric Freshwater Invaders in Southern Alberta Reservoirs
DownloadSpring 2023
At present, one of the most pervasive risks to freshwater ecosystems are invasive species. Invasive species are among the leading antagonists to global biodiversity, since they can out-compete or predate on native species which leads to changes of the structure of food webs and alteration of...

The long-term effects of crop rotation and fertilizer applications on soil health and crop productivity in Alberta
DownloadFall 2022
Long-term agricultural management practices affect soil health. Five long-term rotations at the University of Alberta Breton Plots were sampled as part of the Soil Heath Institute (SHI) North American Project to Evaluate Soil Health Measurements (NAPESHM) in 2019: (1) check (no fertilizer...
