Perceptions of Science and Expertise Among Alternative Ranchers in Alberta, Canada: A Qualitative and Actor-Network Analysis
DownloadFall 2021
Dlusskaya, Kira Konstantinovna
Raising animals has been an important aspect of human food systems for millennia, but with growing climate concerns, the management of animal agriculture, including beef production, needs to adhere to environmental best practices. Determining what these practices are has been the subject of much...

Performance and stability of performance of spring wheat variety mixtures in organic and conventional management systems in western Canada
Download2009
O'Donovan, John T., Navabi, Alireza, Kaut, A. H. E. E., Spaner, Dean, Mason, Heather E.
Wheat (Triticum aestivum L.) variety mixtures represent a relatively unexplored avenue for maintaining and stabilizing yield for both organic and conventional producers. The present study examined the responses of three Canadian western red spring wheat varieties in sole crop and in variety...

Physical and Hydrological Characteristics of Ponds in Reclaimed Upland Landscape Settings and Their Impact on Agriculture Capability
Download1990
Pigot, M. E., Macyk, T. M., Moran, S. R., Trudell, M. R.
In 1985, a one hectare pond developed in the upland reclaimed landscape at Vesta Mine in an area where extensive ponding had not previously been observed. Because of the thickness of the spoil, about 20 to 25 m, and the proximity to the active pit, a few hundred metres, it was inferred that the...

Trudell, M. R., Cheel, D. B., Moran, S. R., Macyk, T. M.
Between 1979 and 1988, the Plains Hydrology and Reclamation Project (PHRP) investigated interactions of groundwater, soils, and geology as they affect successful reclamation of surface coal mines in the plains of Alberta. The overall goal of PHRP was: (1) to predict the long-term success and the...

Predicting Patterns of Regeneration on Seismic Lines to Inform Restoration Planning in Boreal Forest Habitats
DownloadFall 2014
Mapping of oil reserves involves the use of seismic lines (linear disturbances) to determine size of reserves. These linear disturbances fragment forests and in many cases fail to regenerate trees even decades following their use. With the continued rise in anthropogenic disturbances,...

Present and potential effects of anthropogenic activities on waters associated with peatlands in Alberta
Download1990
A literature review and problem analysis of the present and potential effects of human activities in peatlands on the quality and quantity of associated waters is presented in this report. The specific objectives were to describe: 1. The present state of knowledge about waters associated with...

Progress towards the sustainable risk management of clubroot (Plasmodiophora brassicae) of canola on the Canadian prairies
Download2011-01-01
Strelkov, Stephen E., Hwang, Sheau-Fang, Howard, Ronald J., Hartman, Murray, Turkington, T. Kelly
Clubroot, caused by the obligate parasite Plasmodiophora brassicae Woronin, has recently emerged as an important disease of canola (Brassica napus) in central Alberta. Disease development is characterized by the formation of large galls on the roots of affected plants, which hinder water and...

Projecting boreal bird responses to climate change considering uncertainty, refugia, vegetation lags, and post-glaciation history
DownloadSpring 2016
Often referred to as North America’s bird nursery, the boreal forest biome provides a productive environment for breeding birds, supporting high species diversity and bird numbers. These birds are likely to shift their distributions northward in response to rapid climate change over the next...

Regional and local controls of surface water chemistry in the Boreal Plain and Shield transition of Canada
DownloadFall 2010
The Western Boreal Forest exhibits complex hydrogeology juxtaposed with rapid resource development. Predicting surface water chemistry to assess the influence of landuse and climate change is needed. The research purpose was to test if a global model (Gibbs), used to assess water chemistry...

Reimaging Resource Constraints and Affordances: Smallholder, Environment and State Dynamics in Wello, Ethiopia
DownloadFall 2012
In this dissertation, I explore and analyze smallholders’ perceptual and cultural understandings of environmental opportunities and constraints regarding land, soil, rain and trees in mixed-crop-livestock agriculture among rural communities of Wärräbabbo in Wello, northeast Ethiopia. Also, I...
