Western Juniper (Juniperus Occidentalis) Ecology With An Exercise In Remote Sensing Techniques, Elizabeth A. Goralski

Geography Masters Research Papers

Western juniper (Juniperus occidentalis var. occidentalis) has been expanding its biogeographic range since the mid-1800's, resulting in decreased biodiversity, altered wildlife habitat, increased soil erosion, reduced stream flows and reduced forage production. The direct causes of western juniper aforestation are unclear but appear to be related to altered fire regimes, over grazing, and climatic shifts.

This study seeks to determine how Landsat images combined with Digital Orthoquads (DOQs) can be used to examine the geographic distribution of western juniper. Satellite imagery has yet to be applied to the large scale mapping of western juniper aforestation, resulting in the lack of …

Comparing Pixel- And Object-Based Classification Methods For Determining Land-Cover In The Gee Creek Watershed, Washington, Tyler Vick

Geography Masters Research Papers

This study analyzes land-cover types in the Gee Creek Watershed of southern Washington using the pixel-based and object-based image analysis approaches. Landsat imagery has traditionally been used for pixel-based classification and change detection in land-cover studies. In recent years, the availability of high-resolution satellite and aerial imagery have enabled for land-cover classification to occur at scales not possible using traditional Landsat imagery. High-resolution aerial imagery of 1 meter or greater has become readily available for free. Yet, commonly found black and white (or panchromatic) aerial imagery is without the multiple spectrum bands found in Landsat imagery, thereby limiting the accuracy …

Overfishing And Environmental Justice In Marine Fisheries, Kristin Novak

Honors Capstone Projects - All

This thesis focuses on the depletion of marine fisheries, as a resource, from a geographical perspective. The decline and collapse of abundant fisheries worldwide has serious, though largely unaddressed, social implications, and should be considered as an issue of environmental justice. I analyze the processes that have lead to fisheries collapses all over the world, as well as the governance structures, management strategies, and political and economic forces involved. This is examined through two case studies: one, the collapse of cod stocks in Newfoundland and New England in the 1990s after centuries of intensive fishing, and two, the currently stressed …

The Hope Of A New College Town At Western Michigan Through Mixed-Use Development And Creation Of A Student Consumer District, James Paul Eichstaedt

Masters Theses

My research will start with investigations into what an American college town is, what are the uses of Smart Growth and Mixed-Used Development in college towns, and the real estate development practices of universities in The United States and one Canadian university. The four case studies in the thesis are The Ohio State University, The University of Norte Dame, The University of Connecticut, Victoria University at The University of Toronto. Other data was collected from survey respondents of close to 200 hundred students at Western Michigan University. The purpose of the survey was to determine what amenities and housing styles …

The Effects Of Climate Change And Urbanization On The Runoff Of The Rock Creek Basin, Jon J. Franczyk

Dissertations and Theses

Climate changes brought on by global warming are expected to have a significant affect on the Pacific Northwest hydrology during the 21^st Century. Current research anticipates higher mean annual temperatures and an intensification of the hydrological cycle. This is of particular concern for highly urbanized basins, which are considered more vulnerable to changes in climate. Because the majority of previous studies have addressed the influences of either climate or urban land cover changes on runoff, there is a lack of research investigating the combined effect of these factors. The Rock Creek basin (RCB), located in the Portland, OR, metropolitan …

Ecosystem Restoration In The Ouachita National Forest: Evaluating The Pragmatism Of Pre-European Settlement Benchmarks, John Lawrence Davenport

University of Kentucky Doctoral Dissertations

This paper looks at the intersections of nature and culture through a study of forest ecosystem restoration efforts in the Ouachita National Forest (Arkansas and Oklahoma). Ecosystem restoration goals are often informed by a pre-European settlement (PES) condition, with an implicit (and occasionally explicit) assertion that such conditions are both more natural than and preferable to the contemporary state. In many cases resuming pre-suppression fire regimes remains a key mechanism for achieving this restored condition. This study’s three main objectives include: (1) determining how PES benchmarks arose in restoration thought, (2) examining how the choice to use a PES benchmark …

The Relationship Of Globalization In The Development And Success Of The Chilean Wine Industry, Jeanette Kripas

Theses, Dissertations and Capstones

This thesis considers the economic geography of location, distribution and spatial organization of activities across the earth by focusing on the aspects of international trade and development. This will be accomplished by examining the process of globalization within the Chilean wine industry. This research explores several themes: 1) Globalization as a process, including the effects such as interdependence and global brands; 2) The role of globalization in the development of the wine industry; and 3) Whether or not the development of the wine industry accounts for generally positive attitudes toward globalization in Chile. Data analysis includes an examination of how …

Paleohydrologic Reconstruction Of Three Shallow Basins, Slave River Delta, Nwt, Using Stable Isotope Methods, Cherie Mongeon

Theses and Dissertations (Comprehensive)

p>The long-term natural hydrological variability of the Slave River Delta (SRD), NWT, is not well documented and needs to be further developed to provide temporal context to understand and evaluate impacts of Slave River (SR) floodwater influence and climate variability and change on contemporary hydro-ecological doncidiotns of the SRD. The SRD has broad ecological and cultural significance, as it provides extensive habitate for wildlife and is important for local First Nations community who have an historical connection with the delta and its resources. Concners have been raised over recently reported drying trends in the SRD over the past few …

Quantifying Twentieth Century Glacier Change In The Sierra Nevada, California, Hassan J. Basagic

Dissertations and Theses

Numerous small alpine glaciers occupy the high elevation regions of the central and southern Siena Nevada, California. These glaciers change size in response to variations in climate and are therefore important indicators of climate change. An inventory based on USGS topographic maps (l :24,000) revealed 1719 glaciers and perennial snow and ice features for a total area of 39.l5 ±7.52 km². The number of 'true' glaciers, versus non-moving ice, is estimated to be 118, covering 15.87 ± 1.69 Km². All glaciers were located on north to northeast aspects, at elevations >3000 m. Historical photographs, geologic evidence, …

Hydrological Response Patterns And Solute Flux In Canadian Shield Basins: Role Of Different Physical Features And Antecedent Moisture Conditions, Jessica Mueller

Theses and Dissertations (Comprehensive)

Patterns of stream flow in relatively undisturbed Canadian Shield basins are closely linked to their physical and vegetative characteristics and meteorological conditions. The physical characteristics include topography, soil-till composition, depth and structure, slope morphology and bedrock geology. Hydrological flowpaths through, and in-situ chemical processes in the soil-till matrix are influenced greatly by the composition of these features and by the antecedent hydrological conditions preceding a given storm or snowmelt event.

A long term data set, collected by the Dorset Environmental Science Centre, is used to examine eight forested basins within the Muskoka-Haliburton region of south-central Ontario. The basins have a …

Reconstruction Of Peace River Flood Frequency And Magnitude For The Past ∼600 Years From Oxbow Lake Sediments, Peace-Athabasca Delta, Canada, Suzanne Jarvis

Theses and Dissertations (Comprehensive)

Ice-jam flooding in the Peace-Athabasca Delta (PAD) is an important hydrological process for the replenishment of shallow perched basins that support a highly productive northern ecosystem. The PAD is also used by nearby First Nations communities for traditional lifestyle occupations such as hunting and trapping. Previous research on laminated sediments collected from two oxbow lakes periodically connected to major Peace River distributaries has resulted in a 300-year record of flood frequency. In an effort to extend this record and broaden the understanding of the relationships among climate variability, Peace River hydrology, and delta hydroecology, a series of vibracores and gravity …
