Spring 2012
Decades of fish introductions into mountain lakes have altered invertebrate communities. I assessed the current status of fish populations and their effects on crustacean zooplankton communities by sampling 37 lakes in the mountain parks, where stocking practices had been halted over 25 years...

Global melting of mountain glaciers is altering downstream ecosystems. As glaciers disappear, downstream water temperatures are rising while turbidity and nutrient concentrations decline. Here, knowledge gaps exist concerning how these abiotic changes will affect primary producers in glacial...

Natural variation and short-term impact of aspen harvesting on surface stream chemistry in the Boreal Plains
DownloadSpring 2011
This thesis describes the natural variation and influence of aspen harvesting on stream chemical concentration and flow-weighted export from catchments typical of the Western Boreal Plain, Alberta, Canada. The catchment stream discharge and stream chemical concentrations presented are taken from...

Nutrient limitation of periphyton in agricultural streams: Implications for watershed management
DownloadSpring 2021
Freshwater streams are ecologically important as sources of habitat, unique biodiversity, and valued ecosystem services. Yet, stream health can be threatened by intensified nutrient loading derived from adjacent anthropogenic land-uses such as agricultural and municipal developments. Since algal...

Phytoplankton communities as indicators of environmental change and nutrient deposition in the Canadian Rockies
DownloadSpring 2020
Remote mountain water bodies integrate the impacts of regional factors (e.g. climate change, atmospheric pollutants) well because of the relative absence of confounding local perturbations (e.g. human land-use). Climatic factors can alter the abiotic environments within mountain lakes through...

Fall 2017
Multiple novel and rapidly changing environmental factors (i.e. anthropogenic stressors) are increasingly affecting ecological communities, and their functional roles in ecosystems. Consequently, freshwater biodiversity has declined worldwide; however, the functional impacts of this loss should...

The Cell Biology And Ecology Of Heterotrophic Eukaryotes In A Tailings Reclamation Site In Northern Alberta
DownloadFall 2020
The wastewater products from the bitumen extraction process, called tailings, are contained in pits which cover over 77km2 of the Northern Albertan landscape. Reclaiming these tailings is an essential part of the life cycle of oil sands mines. One method under development converts tailings ponds...

The Role of Iron in Suppressing Internal Phosphorus Loading and Toxic Cyanobacterial Blooms in Freshwater Lakes
DownloadFall 2013
Harmful algal blooms occur in nutrient-rich lakes around the world, diminishing the value of these ecosystems for wildlife and humans. Management of algal blooms is an on-going challenge for lake managers and policy makers. The overarching goal of this research was to advance our understanding of...
