Modelling phytoplankton across many scales: transient dynamics, human interactions, and niche differentiation in the light spectrum
DownloadFall 2021
In recent decades freshwater lakes have seen an increase in human presence. A common byproduct of this human presence is anthropogenic nutrient pollution resulting in eutrophication, a term that is becoming all too synonymous with harmful algal blooms. It is well known that phytoplankton...

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...

Perceptions of Science and Expertise Among Alternative Ranchers in Alberta, Canada: A Qualitative and Actor-Network Analysis
DownloadFall 2021
Dlusskaya, Kira Konstantinovna
Raising animals has been an important aspect of human food systems for millennia, but with growing climate concerns, the management of animal agriculture, including beef production, needs to adhere to environmental best practices. Determining what these practices are has been the subject of much...

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...

Responses of aquatic invertebrate assemblages to an iron treatment aimed at reducing internal phosphorus loading
DownloadSpring 2013
This mesocosm study investigates changes in aquatic invertebrate assemblages in response to iron application, a remediation treatment that inhibits internal phosphorus loading in culturally-eutrophied freshwaters. To determine the effects of ferric chloride application on aquatic invertebrates, I...

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...

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...

Tradeoffs Between Environmental Quality and Economic Returns from Agriculture: A Case Study of the Lower Little Bow Watershed, Alberta
DownloadFall 2016
The aim of this study is to evaluate both the costs and benefits of implementing changes to agricultural practices, with the goal of identifying cost effective means of achieving environmental targets and providing supplementary information to policymakers. A suite of agricultural land use...
