Controls On Terrestrial Evapotranspiration From A Forest-Wetland Complex In The Western Boreal Plain, Alberta, Canada, Scott M. Brown

Theses and Dissertations (Comprehensive)

The Western Boreal Plain (WBP) of North Central Alberta consists of a mosaic wetlands and aspen (Populus tremuloides) dominated uplands. This region operates within a moisture deficit regime where precipitation (P) and evapotranspiration (ET) are the dominant hydrologic fluxes. As such these systems are extremely susceptible to the slightest to the slightest climatic variability that may upset the balance between P and ET. Vegetation composition is the dominant control on wetland ET, and itself is extremely dynamic within these wetland environments, which can be attributed to varying moisture regimes along with micrometeorological variations. To address this variability in …

Place And Food: A Relational Analysis Of Personal Food Environments, Meanings Of Place And Diet Quality, Ellen Desjardins

Theses and Dissertations (Comprehensive)

This study investigates the relational layers of meanings that people experience at places in their food environment, and how individuals express a sense of place through their collective interactions with, and understandings of, food places. It also explores the patterns of difference among these meanings of place and sense of place in terms of their potential association with dietary quality. The context of this inquiry was two-fold: first, the need identified by several population health researchers and to re-imagine place as relational and include it in the study of behavioural responses to the changing food environment; and secondly, my interest …

Spatial And Spatial-Temporal Analysis Of Grizzly Bear Movement Patterns As Related To Underlying Landscapes Across Multiple Scales, Barbara Lynn Carra

Theses and Dissertations (Comprehensive)

Studying the movements of grizzly bears (Ursus arctos) in Alberta is imperative for scientifically informed management practices. To properly balance industry requirements with conservation imperatives, it is necessary to understand the spatial and spatial-temporal movement patterns of grizzly bears as they relate to underlying landscape properties. As part of the Foothills Research Institute Grizzly Bear Research Program, this dissertation explored both fine and largescale movement patterns generated from global positioning system (GPS) radiotelemetry data.

Between 1999 and 2005, grizzly bears were captured and radio-collared across western Alberta. The temporal resolution of GPS data collection had a large impact …

Tundra Snow Cover Properties From In-Situ Observation And Multi-Scale Passive Microwave Remote Sensing, Andrew Rees

Theses and Dissertations (Comprehensive)

Tundra snow cover is important to monitor as it influences local, regional, and global scale surface water balance, energy fluxes, and ecosystem and permafrost dynamics. Moreover, recent global circulation models (GCM) predict a pronounced shift in high latitude winter precipitation and mean annual air temperature due to the feedback between air temperature and snow extent. At regional and hemispheric scales, the estimation of snow extent, snow depth and, snow water equivalent (SWE) is important because high latitude snow cover both forces and reacts to atmospheric circulation patterns. Moreover, snow cover has implications on soil moisture dynamics, the depth, formation and …

Bringing Medicine To The Hamlet: Exploring The Experiences Of Older Women In Rural Bangladesh Who Seek Health Care, Md. Abul Hossen

Theses and Dissertations (Comprehensive)

The purpose of this study was to explore the experiences of older women in rural Bangladesh who seek health care. Qualitative methods were used to collect data from 17 older women in Bibirchar Union, Sherpur District, Bangladesh in June 2006. The study is intended to generate findings to help policy makers plan appropriate strategies to improve the health of this highly vulnerable population group.

The findings reveal that women’s culturally and socially determined roles greatly impair their health and play an important role in health-seeking behaviour through a complex web of social, economic, religious/cultural and behavioural interrelationships and synergies that …

Grounding Diaspora In Experience: Niagara Mennonite Identity, Cynthia Anne Jones

Theses and Dissertations (Comprehensive)

This qualitative case study grounds theoretical notions of diaspora in personal accounts of Russian Mennonites living on the Niagara peninsula of Canada. The focus is on successive, complex interrelationships with ‘place’ (in a fixed sense, and a globally connected sense), with attention to gender, generation, and life-stage. How have these individuals experienced diaspora, and how has this influenced their culture and identity? Interrelationships with place are examined within an analytical framework composed of three key elements as identified in diaspora literature: cultural hybridity, social heterogeneity (internal divisions), and responsibility flows. The results are both descriptive and theoretical, featuring first person …

Identifying Potential Carbon Flux Responses To Shifting Hydroecological And Climactic Regimes In The Peace-Athabasca Delta, Caleb W. Light

Theses and Dissertations (Comprehensive)

The CO2 flux response of organic carbon stored in lake sediments and littoral peat contained in sensitive, northern wetlands may contribute to accelerating atmospheric CO2 concentrations. Temperature and moisture conditions are important variables that affect the rate and quantity of CO2 released to the atmosphere from organic matter stored in lake sediments and peat. Antecedent hydroecological conditions also influence the direction and magnitude of CO2 fluxes to the atmosphere in a changing environment. To better understand and characterize the role of antecedent conditions on CO2 fluxes, this study combines paleolimnological reconstructions with laboratory incubations of littoral peat and lake sediment …

Forestry-Based Livelihoods In Central Vietnam: An Examination Of The Acacia Commodity Chain: A Case From Thua Thien Hue Province, Vietnam, Robert Pietrzak

Theses and Dissertations (Comprehensive)

Forestry-based livelihoods in remote Vietnamese communities have been influenced in recent years by forest land allocation schemes, changes to property rights, and forest management devolution initiatives. Examples include the Five Million Hectare Reforestation Program, Project 327, and official “Red Books” that grant long-term land use rights and access rights to villagers. Major challenges to forestry-based livelihoods include disputes over land tenure, conflict between different levels of government, illegal logging practices and harvesting of NTFPs and competition over land for natural versus plantation forests. As a result, forest degradation and rural poverty continue to be debilitating obstacles to development in Central …

An Apple A Day: Exploring Food And Agricultural Knowledge And Skill Among Children In Southern Ontario, Shannon Alberta Kornelsen

Theses and Dissertations (Comprehensive)

While the literature on food has somewhat addressed rudimentary food skills and their importance in the creation and maintenance of a healthy population, there remains a serious lack of research into the importance of food and agricultural skills and knowledge transference to children, especially given the rise in diet-related illnesses. This study focuses on the perceived importance of food and agricultural education initiatives, as well as the opportunities and barriers that exist within the elementary school classroom to incorporate food and agricultural topics, in the context of southern Ontario, specifically Wellington County. Drawing on Wilkin's concept of ‘food citizenship’ as …

A Time Series Analysis: Exploring The Link Between Human Activity And Blood Glucose Fluctuation, Eric A. Sadowski

Theses and Dissertations (Comprehensive)

In this thesis, time series models are developed to explore the correlates of blood glucose (BG) fluctuation of diabetic patients. In particular, it is investigated whether certain human activities and lifestyle events (e.g. food and medication consumption, physical activity, travel and social interaction) influence BG, and if so, how. A unique dataset is utilized consisting of 40 diabetic patients who participated in a 3-day study involving continuous monitoring of blood glucose (BG) at five minute intervals, combined with measures for sugar; carbohydrate; calorie and insulin intake; physical activity; distance from home; time spent traveling via public transit and private automobile; …
