Selective Framing And Narrative As Anthropocentric Agents In Yellowstone: America’S Eden, Breanna Lee Hansen

USF Tampa Graduate Theses and Dissertations

Yellowstone: America’s Eden is but one example of nature documentaries tackling the complexities of nature-culture relationships during the age of the Anthropocene. Yellowstone National Park, the first to be named, is a primary example of how our relationship to the natural world developed through conservation and commodification. Yellowstone: America’s Eden demonstrates how film techniques conceal nature as a human construct through selective framing and narrative. By analyzing editing techniques made in the representation of Yellowstone National Park, this thesis bridges anthropocentrism to nature documentaries. Drawing on interdisciplinary research from media studies, environmental humanities, and anthropology, this thesis analyzes the ways …

Machine Learning For Species Habitat Analysis, Abigail Lavallin

USF Tampa Graduate Theses and Dissertations

Management and conservation initiatives will always be controlled by finite resources, whether financialor temporal. Understanding a species’ spatial ecology, and how its requirements vary across habitats and locations is key to a successful species management plan. During recent decades, it has been noted how many species populations have declined, despite conservation practices working to increase their numbers. The most prevalent impacts affecting fauna populations have come from anthropogenic change in the form of habitat loss and destruction, along with fragmentation, and global climate change. There is a clear need for management practices to now operate on an entire landscape instead …

Climate Change And Liberation In Latin America, Ernesto O. Hernández

USF Tampa Graduate Theses and Dissertations

The purpose of this dissertation is to propose the liberation movements in Latin America as alternative philosophical frameworks to the crisis of climate change. These movements have provided the grounds to identify inequities and injustices and have practiced ethical methodologies to overcome them. Additionally, the movements seek to represent and reflect the value of non-traditional philosophical agents in Latin America. The work focuses on four major Latin American ecological liberation movements; theology, philosophy, pedagogy, and feminism. Eco-Theology advances the role of Religion as the practice of Religação, reexamination, and resetting our relationship with nature by reconnecting with it. Eco-Philosophy of …

Women In Water: An Interpretative Phenomenological Analysis Of Women's Lived Experience As Water And Wastewater Professionals, Pamela Murawski

USF Tampa Graduate Theses and Dissertations

The purpose of this interpretative phenomenological analysis was to explore the lived experiences of women water and wastewater professionals in California. A qualitative methodology and semi-structured interviews provided detail and a rich understanding of women’s occupational choices, pursuits, and roles as told from their own perspectives. The results revealed that while working in water promoted a sense of pride, accomplishment, and empowerment, women continued to fight for equal access and full participation in lucrative water treatment careers. Key issues the women indicated were lack of knowledge of the industry, the necessity of mentorship, access to technical information, and the male-centered …

“Living Creatures Of Every Kind:” An Ecofeminist Reading Of Genesis 1-3, T. G. Barkasy

USF Tampa Graduate Theses and Dissertations

This work will examine the Genesis creation narratives through an ecofeminist critical lens to illuminate the ambivalence regarding both the ecological and feminist concerns pertinent to ecofeminist criticism. While ecology and feminism are major issues in today’s social and political climates, ecofeminism and its presence in biblical scholarship is not as prevalent as one might think. When it is discussed, authors come to varying conclusions on the Bible’s stance about either nature or gender, and discussions that consciously espouse ecofeminist methodology are so far insufficient. This work utilizes the documentary hypothesis in order to examine the parallel narratives of creation …

Behavioral Thermoregulation And Thermal Mismatches Influence Disease Dynamics In Amphibians, Erin Louise Sauer

USF Tampa Graduate Theses and Dissertations

Amphibians are currently the most threatened vertebra taxa on the planet. Hundreds of species are thought to have gone extinct while thousands more have been listed as threatened or endangered over the past few decades. Habitat loss, invasive species, climate change, and disease are all thought to have partially contributed to these declines. Two pathogens in particular, infectious viruses in the genus Ranavirus (simply referred to as ranavirus) and the fungus Batrachochytrium dendrobatidis (Bd), have been associated with global mass mortality events of amphibians. Virulent pathogens such as these tend to impose strong selective pressures on their hosts driving the …

The Effects Of Gopher Tortoise (Gopherus Polyphemus) Herbivory On Plant Community Composition And Seed Germination, And The Effects Of Gut Passage On The Germinability Of Seeds: A Meta-Analysis, Jason C. Richardson

USF Tampa Graduate Theses and Dissertations

Herbivory produces direct and indirect effects on plants and at different spatial scales will have varied consequences. Consumption of plants by vertebrate grazers may affect the plants on an organismal level through direct mortality, on a community level by changing species composition or by altering the rate of succession, and even at a whole ecosystem level by altering nutrient cycles.

The majority of the scientific literature has focused extensively on herbivory by mammals and birds. With regard to mammals, studies have shown how folivory affects individual plants, plant populations, and communities of plants.

Mammals, as well as birds, also ingest …

Using Green Messages To Cue Recycling Tendencies, Danielle Quichocho

USF Tampa Graduate Theses and Dissertations

Recycling of common plastics is a practical way to limit the amount of waste that ends up in landfills, and eventually contributes to various forms of pollution. However, statistics indicate that it is not currently a normalized, prioritized behavior. A pilot study indicated that relying only on preexisting frameworks such as the Elaboration Likelihood Model to understand consumer perceptions simply does not encompass the scope of the topic. Consumer experiences with green messages, especially in the current climate of a saturated advertising market are incredibly complex. Understanding these experiences is also currently being impeded by inconsistencies in how researchers in …

Playing-With The World: Toy Story's Aesthetics And Metaphysics Of Play, Jonathan Hendricks

USF Tampa Graduate Theses and Dissertations

Pixar’s Toy Story (John Lassiter, 1995) is not just a story about toys and the children that play with them, but a demonstration of how we interact with the world. This thesis looks at the way in which both main children, Andy and Sid, interact with their toys and how this interaction is one that is structured by way of what Martin Heidegger calls “Enframing.” In this modality of playing, toys and other things and entities in the world, and the world itself, appear to the children as on-hand resources for use at any time and can be molded, as …

Climate Change Drives Outbreaks Of Emerging Infectious Disease And Phenological Shifts, Jeremy Cohen

USF Tampa Graduate Theses and Dissertations

Climate change is expected to impact species by altering infectious disease outcomes, modifying community composition, and causing species to shift their phenology, body sizes and range distributions. However, the outcomes of these impacts are often controversial; for example, scientists have debated whether climate change will exacerbate emerging infectious disease and which species are at greatest risk to advance their phenology. There reason for these controversies may be that climate change is impacting diverse processes across a wide range of ecological scales, as the interplay between fine-scale processes and broad-scale dynamics can often cause unpredictable changes to the biosphere. Therefore, it …

Chemical Investigation Of Antarctic Marine Organisms & Their Role In Modern Drug Discovery, Jacqueline Lee Fries

USF Tampa Graduate Theses and Dissertations

The chemicals produced by biological systems, whether proteins, peptides, or terpenes, will always provide an intriguing topic for researchers. Invisibly controlling every aspect of nature, these molecules are responsible for life, evolution, and death. Specifically, here is described the secondary metabolites produced by Antarctic marine organisms as well as others, and how they are used to defend or attract other animals while potentially providing health benefits to mankind. This is done through collection, extraction, and separation of individual specimens. The respective mixtures of compounds after isolation are then analyzed via spectroscopic methods such as nuclear magnetic resonance spectroscopy, mass spectrometry, …

Investigation Of Bioactive Metabolites From The Antarctic Sponge Dendrilla Membranosa And Marine Microorganisms, Chris G. Witowski

USF Tampa Graduate Theses and Dissertations

Natural products continue to be a valuable source of compounds in research involving chemical ecology and drug discovery. Secondary metabolites are biosynthesized to benefit the host organism in its environment (feeding deterrence from predators, antibiotic properties to avoid infection, etc.) but these compounds also serve as useful scaffolds in drug discovery applications. The research herein describes both aspects of these two branches of natural products chemistry. The Antarctic sponge Dendrilla membranosa produces diterpenes, of which membranolide A, deters feeding of the predatory amphipod Gondogenia antarctica. A metabolomic study of several sponges was undertaken to determine environmental factors that govern …

Influences Of Yard Management Intensity On Urban Soil Biogeochemistry, Viviana Penuela Useche

USF Tampa Graduate Theses and Dissertations

Soils are critical to ecosystem function as they provide essential nutrients for primary producers, habitat and organic energy for decomposers, and storage of organic matter. Irrigation with reclaimed water is an increasingly popular water conservation strategy; yet its high salinity and nutrient content potentially affect soil properties. In this study, set in a residential neighborhood of Tampa (U.S.). I tested whether there are distinct lawn system management strategies characterized by systematic differences in reclaimed water usage and irrigation and fertilization practices. I then investigated whether soil biogeochemistry responds to lawn system management strategy.

My results indicated that amendment strategy, which …

Differentiating Geo-Spatiotemporal Aquatic Larval Habitats Of Anopheles Gambiae Complex In Urban Agriculture And Urban Non-Agriculture Environments In Accra, Ghana, Samia Mckeever

USF Tampa Graduate Theses and Dissertations

To meet the rising food demands of communities in Accra,Ghana, urban agriculture has been popularized as a way to increase food security and improve nutrition (Donovan et al., 2012). Urban agriculture is defined as "the cultivation of crops at both the subsistence and commercial levels including the keeping of livestock in open spaces in urban areas (Adjaye, n.d.). In Accra, urban agriculture covers 1,091 hectares, employs over one thousand people, and supplies residents with 90% of its vegetables ("Accra Metropolitan", n.d.). Further, 60% of households in Accra participate in backyard farming ("Accra Metropolitan", n.d.). Although urban agriculture provides many benefits …

Spatiotemporal Distribution Of Genus Culex (Diptera: Culicidae) In Usf Ecopreserve, Hillsborough County, Florida, Emily Schwartz

USF Tampa Graduate Theses and Dissertations

Within the state of Florida, there are three arboviruses of public health importance that can cause neuroinvasive disease in humans: West Nile Virus, Saint Louis Encephalitis Virus, and Eastern Equine Encephalitis Virus. Mosquitoes (Diptera: Culicidae) within the genus Culex are known and suspected vectors of these diseases. The vectors of these diseases can be present in urban wetland habitats that allow for exposure to residential communities. Vector ecology must be investigated in order to understand the dynamics of disease transmission. In Hillsborough County, Florida the spatial and temporal distribution of these vectors are not well established. An ecological study was …

Overwintering And Early Season Amplification Of Eastern Equine Encephalitis Virus In The Southeastern United States, Andrea Bingham

USF Tampa Graduate Theses and Dissertations

Eastern equine encephalitis virus (EEEV) is a highly pathogenic arbovirus that causes severe disease, with a mortality rate of approximately 30-35% in humans and 80-90% in horses. Studies dating back to the 1930's have identified many of the epidemiological and ecological aspects of the virus. However, there are several aspects of EEEV's transmission cycle that remain unclear. In the northeastern states, transmission is seasonal, peaking in the late summer months, while in Florida there is year-round transmission of EEEV. Recent phylogenetic studies have also suggested that Florida may serve as a reservoir for EEEV; the virus may periodically be introduced …

A Comparison Of Avian Abundance And Species Richness In Palustrine Emergent Wetlands In Southwest Florida, Matthew P. Miller

USF St. Petersburg campus Master's Theses (Graduate)

Wetlands are commonly thought of as transition areas between dry, upland habitats and deepwater habitats and can be the hydrologic gradient between a dry landscape and a lake or river, or they be can isolated from a flowing or deepwater system and completely surrounded by a dry landscape (Tiner 2001). Wetlands provide a valuable suite of services including providing foraging, nesting and denning habitat for birds, amphibians and other wildlife (Environmental Law Institute 2008; Stolt, et al. 2001). In southwest Florida, population growth has put enormous pressure on wetland landscapes. Wetland regulations in the state of Florida make clear that …

Investigations For Utilizing Pteropods As Bioindicators Of Environmental Change Along The Western Antarctic Peninsula, Paul Mark Suprenand

USF Tampa Graduate Theses and Dissertations

Pteropods are holoplanktonic gastropod molluscs found globally. Although species diversity is greater at lower latitudes, species abundance is greater at temperate and polar latitudes. Declines in pteropod populations have not only been correlated to declines of their major predators, but pteropods have also been used as bioindicators of global environmental changes such as ocean acidification. With high latitude abundances, pteropods provide significant sustenance for species such as the Atlantic salmon in the Atlantic Ocean and Pleuragramma antarcticum in the Southern Ocean. Because pteropods eat phytoplankton and other pteropods, factors that affect pteropod abundance influence many trophic levels. This dissertation explores …

The study responds to the need identified in the community arts literature to offer robust program evaluations that explain the benefits of such programs. The lack of evidence seems to derive not only from the difficulties …

No Honor Among Snails: Conspecific Competition Leads To Incomplete Drill Holes In The Naticid Gastropod Neverita Delessertiana (R Cluz), Jack A. Hutchings

USF Tampa Graduate Theses and Dissertations

The fossil record of drilling predation has been widely used to study predator-prey interactions and their relative importance on long-term evolutionary processes. Incomplete drill holes have been interpreted as indicators of failed attacks due to well-defended prey. However, this interpretation is based on pair-wise interactions between one predator and one prey, a condition commonly compromised in nature. The hypothesis that interference among drilling predators leads to an increase in the relative frequency of incomplete drill holes was tested in the laboratory using the naticid Neverita delessertiana (R cluz) and a common prey, the bivalve Chione elevata (Say). The experiment consisted …

A Remotely Operated Multi-Tracked Vehicle For Subterranean Exploration Of Gopher Tortoise Burrows, William Keese

USF Tampa Graduate Theses and Dissertations

The gopher tortoise is a land tortoise living in the southeastern United States. It is a species in decline and is listed as threatened or endangered in six different states. The gopher (as commonly referred) digs burrows that it uses for many reasons and spends most of its time underground. Problems occur when trying to estimate a population because a gopher tortoise digs more than one burrow. This thesis demonstrates an innovative way to survey and investigate a gopher tortoise burrow hole by using a multi-tracked remotely operated vehicle. The vehicle carried two cameras (fore and aft) and was equipped …

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 …

Development Of A Mangrove Quality Index In Tampa Bay, Florida, Monetta S. Wilson

USF Tampa Graduate Theses and Dissertations

Mangroves are an important resource. They provide a breeding ground for commercially and recreationally important fish, protect shorelines from erosion and improve coastal water quality. Historically, mangroves were undervalued, leading to a loss of 35% of mangroves worldwide and 44% in Tampa Bay due to anthropogenic stressors. Efforts to protect and restore mangroves have led to a variety of management programs. In Tampa Bay the main management program is the Tampa Bay Estuary Program (TBEP). The program has identified the need for simple and easy to use assessment tools to track mangrove quality and aid in mangrove quality. There are …

Condition / Recondition: Reconstruction Of The City And Its Collective Memory, C Lopez

USF Tampa Graduate Theses and Dissertations

Worldwide, dense urban spaces have been organized and transformed by cultural values. However, in many cases, changes in economic and social conditions have resulted in fragmentation of neighborhood typologies, in terms of their physical characteristics and uses. Such spaces are a manifestation of development, expansion, dislocation and marginalization; a condition that can be improved through an architectural and urban strategy which inscribes emerging forces into the neglected zones of marginal territories. The contemporary context calls for a re-evaluation of public space. To fully engage the people, it is a necessary function of public space to blur landscape, architecture and infrastructure, …

Foraminiferal Responses To Arsenic In A Shallow-Water Hydrothermal System In Papua New Guinea And In The Laboratory, Bryan Mccloskey

USF Tampa Graduate Theses and Dissertations

The tropical Indo-Pacific is the location of highest global foraminiferal biodiversity. However, the shallow-water hydrothermal system in Tutum Bay at Ambitle Island, Papua New Guinea, possesses some of the world's highest naturally-occurring [As]. Foraminifers were collected in this intriguing system in 2003 and 2005 as part of a larger project to examine the possible effects of As and other hydrothermal factors on benthic communities. Despite the high ambient [As], a diverse foraminiferal fauna was observed. Foraminferal communities were examined from surface sediment and from material adhered to rubble at locations from 1-300m from venting and from reference sites, at depths …

Eco_Urbanism Restitching Clearwater's Urban Fabric Through Transit And Nature, Daniel P. Uebler

USF Tampa Graduate Theses and Dissertations

Downtown Clearwater has grown to be disconnected from its surroundings due to an adjacent buffer area and the lack of a transit system to bring people into the city. The downtown core is also separated from its neighboring residential areas by an area of vacant land that holds in it the potential to become a gateway into the city. On a macro scale the city has grown to be separated from the Tampa Bay area due to the lack of a mass transit system.

The goal of this project is to create a new "new urbanism" in which transit and …

Ecological Art: Ruth Wallen And Cultural Activism, Susan Birchler

USF Tampa Graduate Theses and Dissertations

Twentieth century modernity has provoked multiple problems ranging from environmental degradation to human rights violations. Globally, diverse communities of people have organized to promote, not just reactive reforms, but a fundamental alteration of the foundational worldview underlying these issues. Radical activists committed their work to promoting an alternative ethos based on egalitarian, democratic, and ecologically-wise concepts. An array of methodologies emerged from these endeavors. More radical political groups focused on cultural tools to engage people in the construction of an alternative worldview. Radical activists utilized two forms of cultural politics: prefigurative politics, the physical presentation of an envisioned future and …
