Augmented Realities And Uneven Geographies: Exploring The Geolinguistic Contours Of The Web, Mark Graham, Matthew Zook

Geography Faculty Publications

This paper analyzes the digital dimensions of places as represented by online, geocoded references to the economic, social, and political experiences of the city. These digital layers are invisible to the naked eye, but form a central component of the augmentations and mediations of place enabled by hundreds of millions of mobile computing devices and other digital technologies. The analysis highlights how these augmentations of place differ across space and language and highlights both the differences and some of the causal factors behind them. This is performed through a global study of all online content indexed within Google Maps, and …

The Effect Of Visual Wulst Lesions And Trigeminal Nerve Sectioning On The Discrimination Of Magnetic Inclination In The Homing Pigeon (Columba Livia), Merissa Acerbi

Honors Projects

The ability of homing pigeons to return to their loft from unknown places has fascinated scientists for centuries. It is well established that homing pigeons, like migratory birds, posses an innate magnetic inclination compass to determine direction by measuring the angle between the magnetic field vector and the Earth's surface. Recent work has indicated that the avian magnetic compass is light mediated and appears to mediate magnetic information to the brain. This occurs via a visual pathway with processing in the visual Wulst area of the forebrain. There is, however, also evidence from other avian species that magnetic direction may …

Factors Influencing The Capacity Of Communities To Respond To Coastal Erosion In The Upper Gulf Of Thailand, Chatchai Intatha

Theses: Doctorates and Masters

Local communities must have a capacity to ameliorate coastal erosion impacts. Since coastal erosion operates over long time frames, understanding this capacity, or the abilities of communities to respond to the impacts and recover to maintain community functions, requires analysis of the past and the present. This study explores factors which influence the capacity of communities to respond to coastal erosion and conversely how exposure to coastal erosion itself affects community capacity.

Mixed methods research was used to investigate the views of respondents in seven coastal villages in the upper Gulf of Thailand, three from an area that has experienced …

Sagebrush Ecosystem Characterization, Monitoring, And Forecasting With Remote Sensing: Quantifying Future Climate And Wildlife Habitat Change, Collin G. Homer

Electronic Theses and Dissertations

Sagebrush (Artemisia spp.) ecosystems constitute the largest single North American shrub ecosystem and provide vital ecological, hydrological, biological, agricultural, and recreational ecosystem services. Disturbances continue to alter this ecosystem, with climate change possibly representing the greatest future disturbance risk. Improved ways to characterize and monitor gradual change in this ecosystem are vital to its future management. A new remote sensing sagebrush characterization approach was developed in Wyoming which integrates three scales of remote sensing to derive four primary continuous field components (bare ground, herbaceousness, litter, and shrub), and four secondary components (sagebrush, big sagebrush, Wyoming sagebrush, and shrub …

Impacts Of Land Cover Changes On Ecosystem Services Delivery In The Black Hills Ecoregion From 1950 To 2010, Suzanne Cotillon

Electronic Theses and Dissertations

Environmental degradation generated by land use choices and human activities is the first driver of change in the provision of ecosystem goods and services. One of the challenges in ecosystem services research is to evaluate the contribution of each land cover unit to ecosystem services delivery while considering multiple services. In this thesis, I develop a framework to assess the capacity of many land covers to independently produce ecosystem services (i.e., potential production) and the capacity of the whole landscape to deliver multiple services to the population (i.e., potential supply). In the first part, this methodology is used to report …

Threshold Responses Of Forest Birds To Landscape Changes Around Exurban Development, Todd R. Lookingbill, Marcela Suarez-Rubio, Scott Wilson, Peter Leimgruber

Geography and the Environment Faculty Publications

Low-density residential development (i.e., exurban development) is often embedded within a matrix of protected areas and natural amenities, raising concern about its ecological consequences. Forest-dependent species are particularly susceptible to human settlement even at low housing densities typical of exurban areas. However, few studies have examined the response of forest birds to this increasingly common form of land conversion. The aim of this study was to assess whether, how, and at what scale forest birds respond to changes in habitat due to exurban growth. We evaluated changes in habitat composition (amount) and configuration (arrangement) for forest and forest-edge species around …

Cartografía, Corredores Y Cooperación: La Búsqueda De Soluciones Transfronterizas En Las Fronteras Amazónicas, David S. Salisbury, Diego B. Leal, Andrea B. Chávaz Michaelsen, Bertha Balbín Ordaya, A. William Flores De Melo, Pedro Tipula Tipula, Maria Luiza Pinedo Ochoa

Geography and the Environment Faculty Publications

Implementation of conservation and development in the Amazon borderlands requires effective transboundary coordination. Updated, readily understandable, and transboundary cartography becomes increasingly essential in Southwestern Amazonia as residents and decision makers attempt to mitigate the socio-environmental challenges and impacts in the borderlands. The lack of updated borderland cartography complicates the planning of development, integration, and conservation projects at a variety of different scales. The Transboundary Geographic Group of Southwestern Amazonia (GTASO) has created a network to continuously exchange geographic information, resulting in a June 2013 workshop and the creation of five transboundary thematic maps of the Amazon regions of Ucayali and …

Plant Community Composition And Structure Monitoring For Agate Fossil Beds National Monument, 2012 Annual Report, Isabel W. Ashton, Stephen K. Wilson, Daniel J. Swanson, Michael Prowatzke, Phil Graeve

United States National Park Service: Publications

Executive Summary

Agate Fossil Beds National Monument (AGFO) plays a vital role in protecting and managing some of the last remnants of native mixed-grass prairie in the region. The Northern Great Plains Inventory & Monitoring Network (NGPN) and Fire Ecology Program (FireEP) surveyed 12 long-term monitoring plots in Agate Fossil Beds National Monument in 2012 as part of an effort to better understand the condition of plant communities in the park. We measured plant diversity and cover, looked for the presence of exotic species that may be newly invading the park, and evaluated the amount of human and natural disturbance …

Analyzing The Foodshed: Toward A More Comprehensive Foodshed Analysis, Meara Butler

Geography Masters Research Papers

Foodshed Analysis is a tool used by researchers to measure the feasibility of providing more local food to a community. That there are economic, environmental, and societal benefits provided by eating locally produced food is a central assumption of Foodshed Analysis research. These benefits, however, are not inherent to a localized food system, but instead are goals that local food system participants must work to achieve. Foodshed Analysis may be a helpful tool that can be used to advise food system reform to the benefit of a community’s economy, environment, and society, but, in order for this tool to be …

An Evaluation Of Data Collected By Middle School And College-Level Students In Stream Channel Geomorphic Assessment, Martin D. Lafrenz

Geography Faculty Publications and Presentations

This project tested the accuracy and repeatability of geomorphic stream channel assessments conducted by two different middle school classes from the Walt Morey Middle School in Troutdale, OR and college students from Portland State University in Portland, OR. Each group surveyed the same three cross-sections in Fairview Creek, a tributary to the Lower Columbia River, in order to assess stream channel geometry, discharge, composition of the bed material, and water quality. The three student groups were all able to accurately document the stream channel geometry, including stream width and mean depth, indicating that these data can be successfully collected by …

Disinvestment And Suburban Decline, Robert Streetar

School of Business Student Theses and Dissertations

Beginning in the mid-1970s, U.S. suburbs started to experience many of the same problems typically associated with earlier inner-city decline including accelerating income decline, increasing family poverty, falling housing prices, growing income polarization, escalating crime, and increasing racial and ethnic diversity.

Conventional wisdom often lays the blame for neighborhood decline on who moves in and who moves out. This is understandable, as neighborhood migration is easily observable. It is the hypothesis of this research, though, that the less visible disinvestment of capital from suburban neighborhoods is an initial cause of suburban decline that precedes and coincides with the more observable …

Gis Prototype Modeling Of Landslide Susceptibility And Risk Perception - Aguas Calientes (Machu Picchu Pueblo), Peru: An Exploratory Approach, Alicia Felice Tyson

Geography and the Environment: Graduate Student Capstones

Tourism is an increasingly important and developing sector of the Peruvian economy and the country is fast-tracking development to accommodate an influx of tourists, reportedly over 1.8 million/year. Situated in the southwest region of Peru, Aguas Calientes (Machu Picchu Pueblo) continues to develop infrastructure to keep pace with this burgeoning tourism industry. Regional geology and hydrology are importation factors influencing the ability to accommodate tourism in Aguas Calientes. Located at the confluence of three rivers, the town is also situated in a watershed with high return intervals for flooding and mass wasting triggered by the sudden, intense rainfall characterizing the …

The Educational Training Of Storm Chasers And Storm Spotters In Relation To Geographical Dispersion Across The United States, Paul R. Zunkel

All Graduate Theses, Dissertations, and Other Capstone Projects

When severe weather strikes, storm chasers and storm spotters confirm that what forecasters and meteorologists are seeing on a radar screen is actually occurring in the field. While some documenters are classically trained (i.e. they have a background in atmospheric science and or meteorology attained from a 4 year university) many others are not. There are currently two organizations available for the weather enthusiast to be a part of, SKYWARN and SpotterNetwork. These organizations give weather enthusiasts a background knowledge into severe weather; however, many weather enthusiasts are not classically trained and most have not taken any formal education in …
