Persistence of subsoiling effects on the soil physical and hydraulic properties in a reconstructed soil
DownloadSpring 2016
Surface mining is one of the most significant forms of anthropogenic disturbance to natural and managed ecosystems. In Alberta, mining disturbs large areas in the Mixedwood Boreal natural region and recovery is often slow because of poor soil quality, specifically the high degree of compaction....

Identification of salt- resistant tree species and genotypes is needed for rehabilitation of lands affected by salinity in Mexico. This dissertation consists of four studies for analyzing the responses of Pinus leiophylla seedlings to salt. In the first study, resistance to salt stress was...

Oil Sands Reclamation With Woody Debris Using LFH Mineral Soil Mix And Peat Mineral Soil Mix Cover Soils: Impacts On Select Soil And Vegetation Properties
DownloadFall 2014
Prior to mining oil sands, soil is salvaged for reclamation and forest stands are harvested for their merchantable timber. Harvest operations leave large amounts of residual woody debris, which has been historically burned or mulched. Woody debris has significant ecological effects and can be...

A simulation/optimization system for modelling timber and old forest under stochastic fire disturbance
DownloadSpring 2011
Stochastic wildfire disturbance contributes to uncertainty in forest management planning. In this study, a system composed of an optimizing forest estate model nested within a Monte Carlo simulation model of stand replacing fires is used to investigate the impact stochastic fire may have on the...

Nitrogen and Sulfur Fertilization Effects on Carbon Sequestration and Greenhouse Gas Emissions in S-deficient Soils
DownloadFall 2016
Depending on management practices, agricultural soils have the potential to be both a source and a sink of greenhouse gases (GHGs). Long-term fertilization and crop rotation management practices are considered to have an impact on carbon (C) sequestration and nitrous oxide (N2O) emissions. Sulfur...

Factors affecting the detectability and eastern distribution of grizzly bears in Alberta, Canada
DownloadFall 2013
Effective and adaptive conservation of a species requires knowledge of trend in abundance and distribution. Monitoring species that are highly mobile, cryptic, and occurring at low densities is especially challenging. This research investigates the local factors affecting the detectability of...

Ecophysiology And Carbon Allocation Of Aspen And Balsam Poplar Seedlings In Response To Drought
DownloadFall 2012
Drought-induced forest mortality has been recorded in every forested continent. Although the effect of drought on plant growth, physiology and ecology have been extensively studied in the past, the physiological mechanism leading to plant mortality under drought conditions are far from being...
