Habitat Use in Undisturbed Forest and the Effect of Variable Retention Harvesting on Pollinator Assemblages (Apoidea, Syrphidae) in the Boreal Forest of Alberta
DownloadSpring 2019
While pollination in agricultural areas has been well studied, pollinators in forests have received much less attention, particularly in the boreal forest. Bees, especially native bees, and hoverflies are the two most important groups of pollinators providing crucial ecological and economical...

An evaluation of hitchhiker seedlings with native boreal species as a revegetation tool of industrially disturbed sites in Alberta, Canada
DownloadSpring 2020
Herbaceous forbs hitchhiked, or co-grown, with a woody species, is a solution to establish both native woody and herbaceous species at recently disturbed sites. The broad study objectives were to (1) assess the growth of fireweed hitchhiked with three deciduous woody species and one conifer over...

Genetic mapping and physiological characterization of water-use efficiency in barley (Hordeum vulgare L.) on the Canadian Prairies
DownloadFall 2011
Temporal or seasonal water deficit is one of the major factors limiting crop yield on the Canadian Prairies. Empirical knowledge suggests that carbon isotope discrimination (Δ13C), through its negative relationship with water-use efficiency (WUE), is a good index for selecting crop varieties...

The role of fine sediment in phosphorus dynamics and stream productivity in Rocky Mountain headwater streams: Possible long-term effects of logging
DownloadSpring 2014
Headwater streams in Alberta’s Rocky Mountains are important in regulating aquatic ecosystem function and a range of downstream water resources but are vulnerable to stresses imposed by disturbances including those exerted by logging. The objectives of this research were to determine if the...

Reaching new heights: Chemical signatures of lodgepole pine trees change with elevation, but not with latitude
DownloadFall 2019
The lodgepole pine (Pinus contorta var. latifolia) is Alberta’s provincial tree and critical to the forest industry. This pine species is the historical host for mountain pine beetle (Dendroctonus ponderosae Hopkins, Coleoptera: Curculionidae, Scolytinae). In western Canada, mountain pine beetle...

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...

Natural and anthropogenic inputs of arsenic and selenium to the environment in the Athabasca Bituminous Sands Region
DownloadSpring 2019
Industrial development of the Athabasca Bituminous Sands (ABS) in northern Alberta, Canada, has raised concerns that emissions of arsenic and selenium to the surrounding landscape and waterbodies have been increasing over time. To test this hypothesis, a comprehensive study of arsenic and...
