A range-wide common garden experiment of white spruce indicates population differentiation in drought tolerance traits
DownloadFall 2019
In western regions of the Canadian boreal forest, mean annual temperature has increased by 1.5 to 2.5 °C, significantly exceeding the mean global temperature increase. Climate conditions have also become drier and together these climate trends have induced widespread growth reductions, dieback...

Estimating the mechanical contribution of willows and balsam poplar in soil bioengineering projects in Alberta
DownloadFall 2019
After the floods in 2013 in Alberta, the effort towards reducing the impact of conventional approaches on the environment and improving the desirable effects of vegetation protecting the water bodies has been an increasing trend in most cities. Soil bioengineering designs with fast-growing plants...

Primates play an important role in the maintenance and functioning of tropical ecosystems. However, habitat loss due to land use conversion threatens the persistence of primates worldwide. Colombia has a diverse fauna of primates with 12% of its terrestrial territory protected under the country’s...

Laboratory-Measured Soil Organic Carbon Mineralization in Soil Samples from Six Long-Term Crop Rotations in Alberta as a Function of Sample Disturbance
DownloadFall 2015
Soil organic carbon (SOC) plays a dual role in soil; as a key compound determining the function and performance of agricultural soils and as the main terrestrial pool of carbon. The carbon content of cultivated soils has been found to depend on management practices. This laboratory incubation...

Species extinctions are inevitable, irreversible and a time-delayed process that is accelerating due to the warming climate and the loss of habitats worldwide. The most threatened vertebrate group in terrestrial ecosystems is amphibians. In this thesis, I assess potential range shifts and...

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...

Trends, causes, and actors of deforestation and forest degradation in the Kalasha valleys of Pakistan: A multi-level analysis
DownloadSpring 2019
Prevention of forest loss is a high priority in Pakistan, where deforestation has been linked to catastrophic flooding in 1992 and 2010. Under the United Nation's REDD+ program, new incentive schemes are developed to encourage forest protection and reforestation, while implementing social...

Analytical developments in the use of resemblance measures in community ecology and applications to boreal forest Carabidae
DownloadFall 2012
Understanding the factors influencing the distribution of species is one of the main goals of ecology. This thesis presents three contributions to better and more efficiently understand the factors defining the composition of ecological communities. First, I studied the impact of anthropogenic...

Tillage Reversal and Nitrogen Fertilization Affected Greenhouse Gas Emissions and Soil Carbon Stability Differently in a Black Chernozem and a Gray Luvisol
DownloadSpring 2015
Improving soil carbon (C) sequestration through land management practices is of great interest due to concerns over global climate change caused by increased atmospheric greenhouse gas (GHG) concentrations. Soil disturbance by conventional tillage (CT) generally accelerates soil organic carbon...

The potential of forest floor transfer for the reclamation of boreal forest understory plant communities
DownloadFall 2011
We examined a direct forest floor transfer reclamation technique to establish a native boreal forest understory plant community on a reclamation site at a coal mine. Forest floor material was salvaged from an aspen-dominated (Populus tremuloides Michx.) donor forest at two depths (15 and 40 cm)...
