Fall 2012
In this study, growth of seven hybrid poplar clones and one pure poplar clone was investigated in relation to leaf, shoot, and root physiology under field conditions. Clones included: Walker (24 - P. deltoides x P. xpetrowskyana), Assiniboine (25 - open pollinated Walker cv. Assiniboine),...

Trembling aspen (Populus tremuloides Michx.) is a dioecious clonal tree species with broad distribution in North America. In dioecious species, sexes are predicted to perform differently, based on the principle of allocation and the energy costs associated with reproduction. Aspen reproduce...

Spring 2013
A major barrier to reclamation after oil sands mining is lack of commercially available, diverse native plant seeds and propagules for revegetation. Potential of LFH (forest floor material) developed on coarse textured soil for establishing native plants and how salvage, placement and storage...

Regional-scale hydrologic settings buffer black spruce regeneration in the presence of post-fire droughts
DownloadSpring 2024
Lanti-Traikovski, Alexander A.
Climate change is increasing the frequency of droughts and wildfires, reducing tree recruitment, and altering post-fire species composition. In Canada’s western boreal forests, postfire recruitment, particularly of drought-intolerant coniferous species like black spruce, has declined in recent...

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...

Selected Aspects of Plant Responses to Elevated pH, Salinity and Drought: Implications for Oil Sands Revegetation
DownloadSpring 2021
Elevated salinity, high pH, and drought are among the most challenging environmental factors affecting the growth and survival of plants in oil sands reclamation areas. In my thesis research, I focused on the selected aspects of these environmental stresses to better understand their potential...

The effects of subsoil ripping on soil physical properties and soil water dynamics on reconstructed soils at Genesee Prairie Mine, Alberta
DownloadSpring 2014
Surface mining activities have significantly depleted natural tree cover, especially trembling aspen (Populus tremuloides), in the Boreal Forest and Aspen Parkland Natural Regions of Alberta. The natural soil profile is usually destroyed during these mining activities and soil and landscape...

The response of Tropical Dry Forests to meteorological drought and El Niño Southern Oscillation
DownloadSpring 2020
As a result of economic pressures from agricultural development, timber extraction, tourism and the expansion of cattle ranching, Tropical Dry Forests (TDFs) are considered one of the most threatened and least protected ecosystems in the neotropics. Interacting with these human-induced effects,...

Tree population responses to extreme climate events to guide reforestation under climate change
DownloadSpring 2018
As climates warm and extreme climatic events occur with more frequency and severity, maintaining forest health and productivity may involve planting seed sources from warmer, drier areas. To guide such reforestation strategies, this work analyzes the risks of both climate change and assisted...
