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...

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...

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...

Spatial and Temporal Variations in Tree Growth, Mortality, and Biodiversity in Alberta Forests
DownloadSpring 2014
Understanding the spatial and temporal variation of tree demographic rates and biodiversity is essential for predicting the dynamics of forest ecosystems and their responses to changing environments. This thesis contributes to that understanding through modeling the long-term change in tree...

Spheroidal gall formation and seedborne infestation by Plasmodiophora brassicae as overlooked aspects of clubroot biology and epidemiology
DownloadFall 2011
Plasmodiophora brassicae, the causal agent of clubroot, can infect many species of the Brassicaceae. Infection results in the formation of galls on the roots of susceptible plants. Most galls are spindle-shaped, but spheroid galls can also develop and are regarded as resistance structures....

Fall 2021
Clubroot, caused by Plasmodiophora brassicae, is an important soilborne disease of canola (oilseed rape; Brassica napus). The effective and sustainable management of clubroot requires a deeper understanding of clubroot epidemiology and improved durability of host resistance. This research aimed...

Clarke, Wayne E., Taheri, Ali, Rolfe, Stephen A., Malinowski, Robert, Haddadi, Parham, Links, Matthew G., Kagale, Sateesh, Strelkov, Stephen E., Djavaheri, Mohammad, Robinson, Stephen J., Parkin, Isobel A. P., Borhan, M. Hossein
Background The protist Plasmodiophora brassicae is a soil-borne pathogen of cruciferous species and the causal agent of clubroot disease of Brassicas including agriculturally important crops such as canola/rapeseed (Brassica napus). P. brassicae has remained an enigmatic plant pathogen and is a...
