Diverting Resources to Turn on Resistance: Influences of Biotic and Abiotic Stresses on Aspen SeedlingsDownload
The interactions between biotic and abiotic stresses and their influence on plant reserves in non-photosynthetic tissues (i.e., roots and stems) and the role of plant reserves in tree defenses are poorly understood. Aspen seedlings grown under different conditions (light, fertilizer) were grouped...
Aspen is a widespread forest tree of high economic and ecological importance in western Canada. The species has also been subject to tree improvement efforts over the past two decades to increase productivity of the forested land base. Successful selection and breeding programs rely on both...
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...
Forest floor protection during drilling pad construction and its benefits for natural regeneration of native boreal forest vegetationDownload
I tested forest floor protection techniques in the construction and reclamation of temporary drilling pads to restore native boreal canopy and understory cover. By covering and delineating the forest floor I hoped to reduce damage to the vegetative propagule bank, so clonal species such as aspen...
Project Report 2002-6
Quality aspen (Populus tremuloides Michx.) nursery seedlings are difficult to produce. In this thesis I explored methods to improve the nutrient status (loading) of aspen seedlings. Tissue nutrient concentrations doubled in seedlings treated with a shoot growth inhibitor (SGI) compared to...
Abstract: Retention of residual trees in \"cutblocks,\" logged blocks of forest, has been proposed as a method to conserve songbirds in landscapes fragmented by clear-cut logging. We examined songbird communities in the boreal mixed-wood forest of Alberta, Canada, to investigate the effect on...
