Cottonwood Riparian Site Selection On The Cheyenne River Sioux Reservation, Julie A. Thorstenson, Diane Rickerl, Janet H. Gritzner

Great Plains Research: A Journal of Natural and Social Sciences

The construction of the Oahe Dam on the Missouri River eliminated thousands of acres ofriparian and floodplain lands on the Cheyenne River Sioux Reservation in South Dakota. Restoration is needed to replace wildlife habitat. This study focused on site selection for native cottonwood (Populus deltoides Bartr. Ex Marsh. ssp. Monilifers (Ait.) Eckenwalde) restoration to help mitigate this loss. Geographic information systems technologies were used to develop a suitability model for cottonwood restoration. Tribal lands were extracted from a digital dataset oflandownership. Those touched by or included in a 46 m border of the Moreau River were candidate sites. Of …

Food Deserts' And 'Food Swamps' In Hillsborough County, Florida: Unequal Access To Supermarkets And Fast-Food Restaurants, Dana Beth Stein

USF Tampa Graduate Theses and Dissertations

Research has shown that the suburbanization of supermarkets has created `food deserts', defined as areas where socially disadvantaged individuals lack access to nutritious food outlets. Additionally, the growing presence of fast-food restaurants has created `food swamps', or areas where socially disadvantaged individuals encounter an overabundance of unhealthy food outlets. While previous studies have analyzed either `food deserts' or `food swamps' using conventional statistical techniques, a more comprehensive approach that includes samples of both healthy and unhealthy entities and considers the variety of available food options is necessary to improve our understanding of the local food environment and related disparities.

The Clash Of Heritage And Development On The Island Of Roatã¡N, Honduras, Alejandro J. Figueroa

USF Tampa Graduate Theses and Dissertations

The present study examines the spatial relationship between archaeological sites on the island of Roatán, Honduras and their topographical and biophysical location, as well as how these relationships are and continue to be impacted by the island's current socioeconomic context. Despite several studies and explorations conducted on the island's history, archaeology, and geography since the early twentieth century, little is known of its place and role within the larger cultural and socioeconomic spheres of interaction in this region: Mesoamerica and the Intermediate Area. Previous archaeological research has shown that hilltops on Roatán were chosen in prehispanic times for the location …

Park Access And Distributional Inequities In Pinellas County, Florida, Kyle Ray Hirvela

USF Tampa Graduate Theses and Dissertations

Although environmental justice research has traditionally focused on environmental disamenities and health hazards, recent studies have begun to examine social inequities in the distribution of urban amenities such as street trees and parks that provide several direct and indirect health benefits to local residents. This thesis adds to this knowledge by evaluating distributional inequities in both distribution and access to parks in Pinellas County, the most densely populated and one of the most racially segregated counties in Florida. An important objective was to determine if neighborhoods with lower levels of park access are more likely to contain a significantly higher …

Nearer, My Farm, To Thee: A Spatial Analysis Of African American Settlement Patterns In Hillsborough County, Florida, Matthew Andrew O'Brien

USF Tampa Graduate Theses and Dissertations

Geographic Information Systems (GIS) have demonstrated their utility in predictively modeling the location of archaeological sites, and providing a framework for cataloging sites eligible for heritage management status. The intent of this GIS-based study is to begin to create a geohistorically organized database of information culled from historic documents and archaeological excavation. In this case study of postbellum land tenure in Hillsborough County, Florida, a GIS-based approach is used to demonstrate the impacts of federal and state land ownership policy decisions during the Reconstruction Era and beyond. GIS data are also used to reveal information about how people use their …

The Dirt On Prehispanic Water Management At Palmarejo, Honduras, Zaida Darley

USF Tampa Graduate Theses and Dissertations

Water is an essential resource for human life. Even in the tropical environment of the Maya Lowlands, water scarcity is a concern, because the region cycles between abundant rainfall and seasonal droughts. To understand how societies flourished during periods of water scarcity, archaeologists have studied prehispanic water management in the Maya Lowlands. Yet, water management research has tended to focus predominantly on large urban Maya populations, excluding smaller-scale societies that face the same challenges associated with water scarcity. This study investigates the neighboring non-Maya society of Late Classic (A.D.650-900) Palmarejo in northwestern Honduras to explore how water management was organized …

Potential Habitat Of Acropora Spp. On Florida Reefs, Katherine Wirt

USF Tampa Graduate Theses and Dissertations

Elkhorn and Staghorn corals (Acropora palmata, A. cervicornis) were listed as threatened species under the Endangered Species Act (ESA) in 2005. The threatened status of these species is unprecedented given the vital role they historically played as major constructors of western Atlantic and Caribbean coral reefs. The goal of my study was to evaluate the current extent of habitat of the two species using a database of reported in situ observations. From these observations, potential habitat maps were produced based on benthic substrata and depth parameters throughout the Florida reef tract using GIS software. Locations of 99% of …

Modeling Roadside Safety Hazards To Predict Annual Crash Cost To Encroaching Vehicles In Rural Road Networks, Isidro Delgado

USF Tampa Graduate Theses and Dissertations

Roadside crashes account for a large portion of total fatal crashes that occur annually in the United States. About 30% of those fatalities are the result of single vehicle run-off-road crashes. A large proportion of these fatal crashes occur in rural roads when vehicles depart from the travel lane and collide with trees or other roadside safety hazards. Many of these run-off-road accidents occur in local roads that carry traffic volumes between 1,000 and 20,000 vehicles per day. Many of these roads are part of the jurisdiction of county authorities faced with the dilemma of having too many "potentially dangerous" …
