Palaeoclimatic Significance Of Perennial Ice Accumulations In Caves: An Example From Scarisoara Ice Cave, Romania, Aurel Persoiu Tiritu

USF Tampa Graduate Theses and Dissertations

Stable isotopes in ice cores drilled in the polar and high-mountain region have been used intensively to reconstruct past climatic changes and atmospheric dynamics. However, no similar studies have been conducted on perennial ice accumulations in caves due to a limited understanding of the links between the external and cave environments, and the way in which the climatic signal can be recorded by the cave ice.

In this thesis, we successfully designed and build a research methodology for the reconstruction of past climatic changes based on perennial ice accumulation in caves, using as example the Scarisoara Ice Cave, Romania. The …

The Influence Of Meteorological Parameters On Rainfall And Severe Weather In Pinellas County, Fl, Cristina A. Mazza

USF Tampa Graduate Theses and Dissertations

Pinellas County is located on a peninsula in Florida that experiences daily patterns of sea breeze associated rainfall mainly during the summer months of June through August. Previously, rainfall patterns, amounts and timing and severe weather in Pinellas County have not been examined considering dominant wind flow patterns, sea breeze circulations and other atmospheric variables. To improve forecasting of local mesoscale phenomena, this project examined the rainfall patterns, amounts and timing and severe weather occurrences that occur as a result of sea breezes and associated prevailing wind regimes within Pinellas County for the months of June, July and August for …

Human-Wildlife Conflict Across Urbanization Gradients: Spatial, Social, And Ecological Factors, Amanda H. Gilleland

USF Tampa Graduate Theses and Dissertations

As suburban and exurban residential developments continue to multiply in urban areas, they encroach on wildlife habitats leading to increased human-wildlife interactions. The animals involved in direct conflict with homeowners are often relocated or exterminated by the homeowners. Often the homeowners contact state licensed wildlife trappers to eliminate the problem animal. In this study I examined how landscape, ecological, and social factors influence the incidence of human-wildlife conflict of thirty two residential areas in the Tampa, Florida metropolitan area. These residential areas, totaling over 300 km2, are part of the urban development gradient representing a range of urban land use …

Application And Refinement Of The Karst Disturbance Index In West Central, Florida, Leslie A. North

USF Tampa Graduate Theses and Dissertations

A hierarchical and standardized environmental disturbance index, specifically designed for karst landscapes, was created by van Beynen and Townsend (2005). To assess the applicability of the index and provide recommendations for its refinement, the index was applied in four west-central Florida counties and interviews were conducted with local and state officials, community planners, and land resource managers. The karst disturbance index consists of 30 indicators contained within five broad categories: geomorphology, hydrology, atmosphere, biota, and culture. Data was readily available for most environmental indicators used to construct the index. Overall, levels of disturbance vary between the counties due to the …

Danger Afoot: Sidewalks, Environmental Justice, And Pedestrian Safety In Pinellas County, Florida, Craig W. Harmak

USF Tampa Graduate Theses and Dissertations

Though often taken for granted, few everyday activities involve so much genuine danger as the hazards associated with motor vehicles. Urban areas are built, modified, and/or deconstructed with motoring in mind. Also true is that few are at as much risk, as are those pedestrians who dare to cross paths with motor vehicles. Unfortunately, all too often, pedestrians are casualties of encounters with the ubiquitous automobile. The Tampa-St. Petersburg-Clearwater, Florida metropolitan statistical area (MSA) has recently been deemed, by one study, to be the nation's second most dangerous MSA for pedestrians. Using information on pedestrian/motor vehicle accident sites, sidewalk location …

Hurricane Forecasting, Warning And Response Systems: A Lake Wales Public Perception Study, April E. Raulerson

USF Tampa Graduate Theses and Dissertations

This research investigates the public perception of hurricane forecasting and warning systems with a view to improving response activities. The hazard literature shows that the effectiveness of such systems is contingent upon on the smooth operation of all components of the system and that warning recipients fully understand the implications of the warning message by taking appropriate action. It is argued that public perception of warning systems will vary depending on various socio-demographic factors, such as age, gender, level of education, socioeconomic status and area, factors that will ultimately influence overall effectiveness. To test this, a questionnaire survey was undertaken …

Assessing Human-Environmental Impacts On Colorado's 14,000- Foot Mountains, Jon J. Kedrowski

USF Tampa Graduate Theses and Dissertations

This research focuses on documenting and analyzing the factors that affect mountain climbing in the state of Colorado and assessing the potential environmental impacts caused by the growing number of climbers visiting the Fourteeners—the 58 mountain peaks located within the Rocky Mountains exceeding an elevation of 14,000 feet. Key objectives were to: 1. identify factors that have a significant effect on mountain climbing frequency; 2. collect information from physical trail and route evaluation to develop an interim classification index; 3. combine relevant variables to formulate a composite Fourteeners Environmental Degradation Index (FEDI) and use it to evaluate, rank, and compare …

Modeling Community Risk And Vulnerability To Multiple Natural Hazards: Hillsborough County, Florida, Christopher T. Emrich

USF Tampa Graduate Theses and Dissertations

Multiple hazard risk and vulnerability are two topics that are at the forefront of hazards research that looks at the hazardousness ofplace. However, no definitive framework that encapsulates measures o f both risk and vulnerability into hazards theory has been developed. Indeed, risk and vulnerability have been used interchangeably. Consequently, populations often encounter high risk environments with little understandingofwaystolimitvulnerability. Thesituationisaggravatedbyincreasing populations and concomitant development ofhigh risk areas. Hillsborough County, Florida, is perhaps the archetype ofthis problem, having experienced rapid urban growth while giving scant attention to the hazardousness ofthe environment.

This research, therefore, looks at the hazardousness of place, focusing …

Habitat Disturbance Within An Urban Forest Fragment, Tampa, Florida, John Forest Turbiville Jr.

USF Tampa Graduate Theses and Dissertations

The purpose of this study is to determine the effects of forest fragmentation on a forest fragment in south Tampa, Florida. To determine these effects, several research objectives are defined, which include: (1) an historical analysis of the development and fragmentation of the study area; (2) documentation of the effects of fragmentation on the site; and (3) development of a management policy relating to site-specific fragmentation effects.

Forest fragmentation and its attendant human impacts have altered many of the natural physical and biological processes associated with the three ecosystem types present within this forest fragment. These ecosystems include pine flatwoods, …

Analysis Of Lead In Soils Adjacent To Interstate 275 In Tampa, Florida, Mark R. Hafen

USF Tampa Graduate Theses and Dissertations

Analysis of two hundred and twenty-four soil samples collected at logarithmic intervals on perpendicular transects adjacent to Interstate Highway 275 in Tampa, Florida revealed that thirty-five percent of the samples contained health-threatening levels of lead (greater than 500 ppm), although the pattern of contamination was not predictable. Twenty-two of the thirty-two transect locations extended toward residential areas and, of these, twenty contained soil lead values dangerous to humans. This analysis also revealed that soil lead does not decrease logarithmically with distance from the highway, as shown in other studies. Soil lead at 3, 9, 27, 81, 243, 729, and 2187 …
