Conservation of boreal moth communities in the mixedwood boreal forests of northwestern Alberta: Impacts of green tree retention and slash-burning
DownloadFall 2012
Green tree retention (GTR), which involves leaving dispersed or clustered live trees on harvested stands, is being adopted as an alternative to clear-cutting, and to conserve biodiversity on managed forests. This thesis examines the post-harvest (7-10yrs) recovery of boreal moths following...

Long Term Dynamics And Potential Remediation Of Fine Textured Soils And Ground Water Contaminated With Chlorinated Organic Compounds And Salts
DownloadFall 2019
Contamination of land, water, and air is a widespread concern often associated with anthropogenic activities. Remediation of contaminated sites is necessary to minimize negative impacts on human health and the environment and allow for safe, productive use of land. Although contaminated sites...

A century of landscape change in the southern Rocky Mountains and Foothills of Alberta: Using historical photography to quantify ecological change
DownloadSpring 2017
Throughout the Rocky Mountain regions of North America fire regimes have been altered towards longer fire return intervals in the 20th century as compared to the 18th and 19th centuries; this has been accompanied by losses of grassland and open canopy woodlands due to encroachment by closed...

Modeling the impacts of recent climate change on ecosystem productivity across North America
DownloadFall 2015
There is evidence of warming and changes in precipitation over recent decades in most regions of North America (NA) that are affecting ecosystem productivity. The impacts of these changes on land-atmosphere carbon exchange over a wide range of biomes are spatially heterogeneous and uncertain. In...

A Proposed Experimental Methodology for Assessing the Effects of Biophysical Properties and Energy Content on Live Fuel Flammability
DownloadFall 2016
The effectiveness of fire management tactics and safety of firefighters strongly depend on the reliability of fire behaviour predictions that is currently limited by a lack of understanding of the flammability of live fuel. Until now fire modeling has been primarily based on the flammability of...

Assessment of soil capping for phosphogypsum stack reclamation at Fort Saskatchewan, Alberta
DownloadFall 2009
Phosphogypsum (PG), an acidic byproduct of phosphoric acid production during phosphate fertilizer manufacturing, is commonly stacked on the facilities and capped with soil at decommissioning. The research evaluated soil capping depth (0, 8, 15, 30, 46, 91 cm) effects on response of five seeded...

Restoration Of Sagebrush Grassland For Greater Sage Grouse Habitat In Grasslands National Park, Saskatchewan
DownloadFall 2020
Populations of Greater Sage-grouse (Centrocercus urophasianus Bonaparte [Phasianidae]; hereafter Sage-grouse) have been in decline in North America for the last 100 years; since 1988, the Canadian population has declined by 98 %. Initial declines of Sage-grouse populations were likely due to...
