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 …
Inter-Species Interactions: Effects Of Spatial Proximity Of Breeding Burrowing Owls (Athene Cunicularia) And Mountain Plovers (Charadrius Montanus) On Mountain Plover Nest Success, Lindsey Messinger
Geography and the Environment: Graduate Student Capstones
Predator-prey interactions are complex and direct interactions between predator-prey pairs are difficult to distinguish due to direct and indirect effects of additional predator-prey interactions. While most studies evaluating the impact of predators on prey concentrate on consumption (mortality of prey caused by a predator), there are a variety of interactions that take place between predators and prey that may not result in mortality. These in direct impacts of predation have been found to influence micro- and macro- habitat use, time allocation patterns, species distribution, population growth, and species interactions and can be just as strong or stronger than consumptive effects.

The cost, implementation and maintenance of a GIS is a costly endeavor however it benefits both the County, State and the general public. County Assessor Office GIS systems have directly influenced the field of Land Surveying both positively …
Potential Wolverine Habitat Vs. Winter Recreation. Conflict In Colorado!, Paul Quigley
Potential Wolverine Habitat Vs. Winter Recreation. Conflict In Colorado!, Paul Quigley
Geography and the Environment: Graduate Student Capstones
The Global list of endangered species of flora and fauna is growing, with the most highly specialized species often at ‘critically endangered’ status. Managing these populations effectively involves numerous and varied organizations, conflicting motivations, arbitrary anthropogenic boundaries and often most importantly, data compilation and management. We are seeing many more reintroductions of locally extirpated species back into habitats of historical prevalence – and as extreme a method of conservation as this is, there is still a need for more extreme methods. High profile and highly specialized endangered species are often managed in a ‘crisis’ mode, where complex behaviors and interactions …

Surface Modeling Topsoil Distribution On A Reclaimed Coal-Mine Site At Blackmesa Mine Complex, Kayenta, Arizona, Janine Ferarese
Geography and the Environment: Graduate Student Capstones
A necessary precursor to ensure proper vegetation growth on reclaimed coal-mine areas is even distribution of topsoil. This capstone discusses development of surface models to describe the accurate determination and visualization of the distribution of topsoil. Prediction surfaces from topsoil-depth point samples were created using the surface interpolation methods, Inverse Distance Weighted and Kriging. The validity and accuracy of each method was assessed to determine the best method to evaluate actual topsoil distribution at a coal mining site. The model can be utilized by non- spatially trained personnel working in the mining arena as an aid in assessing how appropriately …
From Lakes To Plants: Spatial Assessment Of Vegetation Dynamics Along 52 Disappearing Lakes In The Boreal Forests Of Alaska From 1984-2009 In The Yukon Flats Wildlife Refuge, Steve Ewest
Geography and the Environment: Graduate Student Capstones
A spatial assessment of vegetation change along the areas of shrinking lakes was conducted in 2011. The analysis utilized Landsat TM/ETM imagery bands 3 and 4 to calculate NDVI (normalized difference vegetation index) from 1984 to 2009 and applied cell and zonal statistics to measure the change as well as create an animation of the change. Also, three 30 meter bands and the zonal averages for the maximum values were assessed. The band in the 60-90 buffer bands has the greatest ratio amount of the maximum vegetation values when compared to the 0-30 meter and the 30-60 meter buffered bands. …
Mapping In Philanthropy: Exploring The Use Of Mapping In Foundation Grantmaking, Jim Casey
Mapping In Philanthropy: Exploring The Use Of Mapping In Foundation Grantmaking, Jim Casey
Geography and the Environment: Graduate Student Capstones
Foundations provide grants to nonprofit organizations in our communities, who then provide services locally. Choosing which nonprofit to fund, and which not to fund is difficult. This study examines current uses and upcoming uses of mapping and Geographic Information Systems (GIS) as part of funding decisions made by foundations. Foundations engaged in strategic funding, especially that which targets specific populations are more likely to use GIS and geospatial analysis in funding decisions. Grantmaking in response to proposals requires less strategic analysis and calls for mapping much less by comparison. As a field, nationally foundations and nonprofits have identified many uses …
Developing Tornado Climatology In The Southern Great Plains Per Phases Of Prominent Oceanic Oscillations, Nicholas M. Fillo
Developing Tornado Climatology In The Southern Great Plains Per Phases Of Prominent Oceanic Oscillations, Nicholas M. Fillo
Geography and the Environment: Graduate Student Capstones
Meteorologists are continually working toward a greater understanding of which atmospheric environments are most conducive for tornado development. This Capstone project analyzed tornado occurrences across Texas, Oklahoma, Arkansas and Louisiana during the period 1950 through 2009 to determine if any correlation exists between the location and frequency of tornado activity and the phases of the El Nino-Southern Oscillation, the Atlantic Multidecadal Oscillation and the Pacific Decadal Oscillation. While it was determined that no phase of any of the oscillations studied was significantly more dominant over the other(s) concerning frequency, this project does identify some spatial shifts in tornado activity depending …
Determining Heritage Oak Tree Susceptibility To Sudden Oak Death Using Gis Risk Analysis, Michelle M. Guzdek
Determining Heritage Oak Tree Susceptibility To Sudden Oak Death Using Gis Risk Analysis, Michelle M. Guzdek
Geography and the Environment: Graduate Student Capstones
Sudden Oak Death (SOD), caused by the pathogenic water mold Phytophthora ramorum, has killed hundreds of thousands of oak trees in the California coastal regions, with redwood-tanoak forests being hit the hardest (Shoemaker et al., 2007). The term “sudden oak death” is used to describe the disease, because of how rapidly the pathogen has killed otherwise healthy tanoaks, virtually in a matter of weeks (COMTF 2010). SOD was first reported in California in 1994 and is believed to have originated from infected nursery or ornamental plants, but the source has never been identified (Mascheretti et al. 2008).
Using Gis To Determine Wind Harvesting Potential To Help Offset Boulder County's Yearly Energy Usage To Become A More Sustainable County, Pete Coventry
Geography and the Environment: Graduate Student Capstones
This project focuses on Boulder County, Colorado as a case study to demonstrate how a Geographic Information System (GIS) can identify potential wind harvesting areas. A step by step demonstration will illustrate the steps needed to determine such harvesting areas and their wind potential. Once potential wind harvesting areas have been identified, concluding analysis will determine the amount of energy generated in efforts to offset current energy use. Harvesting wind has dated back to the 7th century and is looked at as a mature technology (Edwards 2003). Over the past few decades, public attitudes towards wind harvesting is becoming …

Creating A Habitat Suitability Index Model For Argali Sheep (Ovis Ammon), And Siberian Ibex (Capra Sibirica) In Ikh Nartin Reserve, Mongolia, Nanette Bragin
Geography and the Environment: Graduate Student Capstones
Mongolia is a country with a park system of protected areas, preserving native flora and fauna. In order to inform decision makers about the status of endangered species and park land health, two species of concern, the Argali sheep (Ovis ammon) and Siberian ibex Capra siberica) in the Ikh Nart Reserve in Mongolia were studied. A Habitat Suitability Index Model was developed to study the Argali and ibex habitat preference and discern if the reserve and core zone offer optimal habitat. A total of 57 animals were examined, creating 95% and 50% home range kernels, and minimum convex polygons. The …

The Scope And Nature Of Panhandling And The Related Crime In Denver, Colorado, Megan A. Gall
Geography and the Environment: Graduate Student Capstones
Nationally, increases in the number of panhandlers and homeless people are associated with social and economic issues and are the subject of public policy debate, sociological inquiry and public interest (DHPG 2003). Panhandlers and homeless people are collectively called transients for this research. In the 1950s, the deinstitutionalization of the mentally ill caused the first major influx of homelessness. Discrepancies between affordable housing and wages grew through the 1960s and 1970s and the problem did not gain national attention until the 1980s (DCEH n.d.). The increased attention is primarily due to the continued scarcity of housing, increasing discrepancies between housing …
