Reimagining The Potential Of Earth Observations For Ecosystem Service Assessments, Frank Muller-Karger

Marine Science Faculty Publications

The benefits nature provides to people, called ecosystem services, are increasingly recognized and accounted for in assessments of infrastructure development, agricultural management, conservation prioritization, and sustainable sourcing. These assessments are often limited by data, however, a gap with tremendous potential to be filled through Earth observations (EO), which produce a variety of data across spatial and temporal extents and resolutions. Despite widespread recognition of this potential, in practice few ecosystem service studies use EO. Here, we identify challenges and opportunities to using EO in ecosystem service modeling and assessment. Some challenges are technical, related to data awareness, processing, and access. …

The Upwelling Groundwater Flow In The Karst Area Of Grassano-Telese Springs (Southern Italy), Francesco Fiorillo, Guido Leone, Mauro Pagnozzi, Vittorio Catani, Giovanni Testa, Libera Esposito

KIP Articles

The hydraulic phenomenon of upwelling groundwater flow affecting the karst area of the Grassano-Telese springs (southern Italy) has been investigated through piezometric measurements, discharge, and chemical–physical monitoring of springs, radon activity included. Locally, both large karst springs and sulfurous thermal springs are closely located, and raise several questions on their origin. In this study, the phenomenon of the upwelling flow is supported by different types of evidences: Amazing density of sinkholes connected to hypogenic speleogenesis processes, constancy of temperature, and hydraulic conductivity of spring water, change of radon activity during the hydrological year, increasing of the hydraulic head with depth. …

Documenting Evolution: Comparing And Contrasting Late Mesozoic And Late Cenozoic Molluscan Patterns, Joshua Slattery

USF Tampa Graduate Theses and Dissertations

Despite major advances, evolutionary theory still has numerous shortcomings in terms of fully understanding the controls on speciation and diversification. A major factor limiting our knowledge is how biology and paleobiology view speciation from separate micro- and macro-evolutionary perspectives, respectively. Biologists typically examine microevolutionary changes within species from various biogeographic, behavioral, morphological, and genetic perspectives, which contrasts to the macroevolutionary approach of most paleobiologists, who have examined the same phenomena at larger scales but with the standpoint of time, have also concentrated on aspects of global or regional diversification (e.g., richness, origination rates, and extinction rates) over the long-term. Noticeably …

Environmental Legacies Of Pre-Contact And Historic Land Use In Antigua, West Indies, Anthony Richard Tricarico

USF Tampa Graduate Theses and Dissertations

Hurricanes Irma and Maria have recently demonstrated once again the susceptibility of contemporary populations across the Caribbean to climate-driven events. For islands such as Antigua in the eastern Caribbean, this vulnerability is partly a legacy of prior land use. As such, the actions of pre-Contact and historic period inhabitants are intertwined with contemporary socio-ecological challenges faced by Antiguans today. This research sought to understand the relationship between land use and land degradation from ca. AD 100 to the present in eastern Antigua utilizing two markers of anthropic activity: soil stability and soil quality. Specifically, this research sought to examine how …

Anton Wilhelm Amo's Philosophy And Reception: From The Origins Through The Encyclopédie, Dwight Kenneth Lewis Jr.

USF Tampa Graduate Theses and Dissertations

Diversity and the concept of race are, or should be, central concerns both for the history of philosophy and for our current political reality. Within academic philosophy, these concerns are expressed in the growing demand for minority representation within the canon, which is overwhelmingly white and male, especially in early modern philosophy. Furthermore, until now, historians of philosophy have not spent the time necessary to uncover various designations such as “Negro”, “Moor”, “Ethiopian”, etc., in early modern Europe, and from there to understand how these shaped philosophical reflections on human diversity. In my research, I relate Anton Wilhelm Amo (c. …

Low-Income Access To Employer-Based Transit Benefits: Evidence From 10 Large Metropolitan Regions, Andrea Hamre

Journal of Transportation Demand Management Research

While national aggregate statistics suggest employer-based transit subsidies may be inaccessible to the majority of the working poor, this is the first study to investigate the subject with disaggregate data while controlling for additional factors. This study uses household travel surveys for 10 of the largest Metropolitan Planning Organizations, grouped into seven cases. In each case, the share of workers offered an employer-based transit subsidy is lowest for workers in the lowest income quintile. Binary logistic regression results for the odds of being offered an employer-based transit subsidy are presented for two cases, Washington, DC, and Denver, CO, and the …

Support Received From The Dissertation Advisor And The Graduate Student Success Of Doctoral Students Majoring In The Sciences, Brittany N. Sheehy

USF Tampa Graduate Theses and Dissertations

This quantitative study utilized surveys to explore how science doctoral students receive support from their dissertation advisors and its relationship to graduate student success outcomes. The survey was distributed to active doctoral students majoring in the sciences at one large, public, Southeastern University. Within examining how the support science doctoral students receives relates to graduate student success outcomes, the study also examined additional factors that could influence graduate student success such as the participant size of the laboratory group, experience with undergraduate research, and time in program.

Findings revealed that on average science doctoral students report receiving more psychosocial support …

Essays On Migration Flows And Finance, Suin Lee

USF Tampa Graduate Theses and Dissertations

In the first essay, I examine stock market implications of state-to-state migration flows that are known to provide the basis for social and business networks. I observe sizeable and robust excess return comovement between migration-flow receiving and sending states at both the individual stock and the state portfolio levels. Although I find that migration flows are associated with firms’ business activities, this comovement is not fully explained by economic fundamentals and decreases substantially when firms relocate to other states. In line with the view that migration networks form the basis for a common investor base for receiving and sending states …

Population Fragmentation Leads To Morpho-Functional Variation In British Red Squirrels (Sciurus Vulgaris), Philip G. Cox, Philip J.R. Morris, Andrew C. Kitchener

School of Geosciences Faculty and Staff Publications

It is well-known that population fragmentation and isolation can lead to rapid morphological and functional divergence, with the effect being particularly well-documented in rodents. Here, we investigated whether such a phenomenon could be identified in the Eurasian red squirrel (Sciurus vulgaris), which was once widespread across the majority of Great Britain, but suffered a severe population decline across the 20^th century, leaving a highly fragmented distribution. The aim was to test for morphological and biomechanical variation of the mandible between the remaining British red squirrel populations. Linear and geometric morphometric methods were used to analyse shape in …

Water Scarcity In The Face Of Hurricanes: Improving The Resilience Of Potable Water Supplies In Selected Florida Counties, Fautemeh Sajadi Bami

USF Tampa Graduate Theses and Dissertations

Severe storms can threaten the reliability and accessibility of drinking water supplies. The state of Florida is frequently impacted by hurricanes and is often struck more than once a year. An example of this can be found in 2017 when hurricanes Harvey, Irma, and Maria caused much damage. Compromised utilities, well contamination, and shortages in bottled water and ice are just some of the problems that may threaten peoples’ drinking water.

Faced with these issues, preparation and response efforts must be effective in order to promote human health. Recent events like Hurricane Irma caused shortages in potable water which suggest …

Genome Size And Host Specialization In Parasites, Nicholas Theodore Ogburn

USF Tampa Graduate Theses and Dissertations

In parasites, there are several examples of changes in genome size linked to a parasitic lifestyle—with some species having greatly reduced or expanded genome sizes relative to free-living non-parasitic relatives. What is unknown is whether there is correlated evolution between genome size and host specialization, and whether there is a generalizable framework in predicting genome size evolution in parasites using their genetic architecture and host use ecology. Here, I tested whether genome size of 96 eukaryotic parasites across a wide variety of taxa correlates with host specialization, quantified by the number and phylogenetic relatedness of host species they parasitize. I …

Assessing Palm Decline In Florida By Using Advanced Remote Sensing With Machine Learning Technologies And Algorithms., Christopher B. Hanni

USF Tampa Graduate Theses and Dissertations

Native palms, such as the Sabal palmetto, play an important role in maintaining the ecological balance in Florida. As a side-effect of modern globalization, new phytopathogens like Texas Phoenix Palm Decline have been introduced into forest systems that threaten native palms. This presents new challenges for forestry managers and geographers. Advances in remote sensing has assisted the practice of forestry by providing spatial metrics regarding the type, quantity, location, and the state of heath for trees for many years. This study provides spatial details regarding the general palm decline in Florida by taking advantage of the new developments in deep …

Storm Surge And Evacuations In Pinellas County, Christianne Pearce

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to determine evacuation decisions of residents in Pinellas County, a vulnerable area in Florida, during Hurricane Irma in 2017, and whether those decisions will impact their future decisions to evacuate. This study also examines the resident’s perception of storm surge flooding during a hurricane. To understand evacuation decisions and storm surge perceptions a survey was conducted on residents in vulnerable areas of Pinellas County. The survey examined multiple aspects including the role of media, relationships, and sociodemographic status on decision making. Another aspect examined if their decision to evacuate for Hurricane Irma will impact …

Moving Away From The West Or Taking Independent Positions: A Structural Analysis For The New Turkish Foreign Policy, Suleyman Senturk

USF Tampa Graduate Theses and Dissertations

This paper focuses on understanding and explaining the change of Turkish foreign policy,particularly in the last decade. Many observers have expressed a suspicion that Turkey is abandoning its Western-centric alignment and gradually shifting its axis. The thesis argues that rather than a shift, Turkey is taking an independent position. It maintains that the end of the Cold War and the change in the international structure from bipolarity to unipolarity has provided incentives for countries with some degree of material capabilities to pursue independence from the U.S. policy preferences. This study analyses structural effects on the behavior of Turkey.

Dna Barcoding Of Fish Eggs In The Gulf Of Mexico, Makenzie Burrows

USF Tampa Graduate Theses and Dissertations

DNA barcoding of fish eggs is a relatively new technique that enables more accurate identification of early life stages of ecologically and economically important fish species. Using DNA barcoding of individual planktonic percomorph eggs, this thesis determines putative spawning locations of neritic and oceanic fish species in the Gulf of Mexico (GoM). Surveys at 40 stations in the Gulf of Mexico showed a clear delineation of spawning sites, with neritic fish eggs generally found on continental shelves, and oceanic fish eggs found at the surface of deeper waters. However, samples collected between Florida and Cuba revealed exceptions to this trend …

Estimation Of Number Of People Living In Developing Countries That Received Water From A Spring Source, Prapti Shinde

USF Tampa Graduate Theses and Dissertations

In the year 2000, 170 countries decided to stand together and solve some primary and common global problems like poor health, water, and sanitation. Obtaining access to safe drinking water is every individual’s right. The UN defines safe drinking water as “the water required for each personal or domestic use must be safe, therefore free from micro-organisms, chemical substances and radiological hazards that constitute a threat to a person's health” (UNDESA, 2014). This thesis focuses on identifying the number of people who potentially receive spring water from a piped source in rural mountainous areas. There are three significant steps and …

"I Think Of The Future": The Long 1850s And The Origins Of The Americanization Of The World, Joshua Taylor

USF Tampa Graduate Theses and Dissertations

While historians often point to the rise of the United States as a major global player and technological leader on the world stage in the 1890s and early 1900s, this study argues it was the 1850s, not the 1890s, that this transition occurred. It utilizes transnational methodologies to analyze European perceptions of the United States, American international businessmen, and new ways Americans thought and talked about their place in the world. During the 1850s, European travelers to the United States began to recognize the young nation was taking the lead in technological innovation, while American businessmen like Samuel Colt began …

Off-The-Grid In An On-Grid Nation: Household Energy Choices, Intra-Community Effects, And Attitudes In A Rural Neighborhood In Utah, Eileen Smith-Cavros, Arianna Sunyak

Journal of Ecological Anthropology

This research is an investigation of the perceived positive and negative aspects of off grid living in a middle to upper-class neighborhood in rural Utah in which no public utility grid was available for connection. Off-grid living is defined as unconnected to a public utility power grid, water, or sewer system. In the researched community, all individuals lived off-grid on minimum twenty-acre lots of land with single-household dwellings. We used surveys with closed and open-ended questions to qualitatively explore the local social effects (from individual attitudes to group identity to household economics to conservation attitudes) off-grid living had on individuals …

Mississippi River And Campeche Bank (Gulf Of Mexico) Episodes Of Cross-Shelf Export Of Coastal Waters Observed With Satellites, Daniel Otis

Marine Science Faculty Publications

The cross-shelf advection of coastal waters into the deep Gulf of Mexico is important for the transport of nutrients or potential pollutants. Twenty years of ocean color satellite imagery document such cross-shelf transport events via three export pathways in the Gulf of Mexico: from the Campeche Bank toward the central Gulf, from the Campeche Bank toward the Florida Straits, and from the Mississippi Delta to the Florida Straits. A catalog of these events was created based on the visual examination of 7280 daily satellite images. Water transport from the Campeche Bank to the central Gulf occurred frequently and with no …

Biogeochemical Argo floats, profiling to 2,000-m depth, are being deployed throughout the Southern Ocean by the Southern Ocean Carbon and Climate Observations and Modeling program (SOCCOM). The goal is 200 floats by 2020, to provide the first full set of annual cycles of carbon, oxygen, nitrate, and optical properties across multiple oceanographic regimes. Building from no prior coverage to a sparse array, deployments are based on prior knowledge of water mass properties, mean frontal locations, mean circulation and eddy variability, winds, air-sea heat/freshwater/carbon exchange, prior Argo trajectories, and float simulations in the Southern Ocean State Estimate and Hybrid Coordinate Ocean …

Subglacial Hydrological Control On Flow Of An Antarctic Peninsula Palaeo-Ice Stream, Robert D. Larter, Kelly A. Hogan, Claus-Dieter Hillenbrand, James A. Smith, Christine L. Batchelor, Matthieu Cartigny, Alex J. Tate, James D. Kirkham, Zoë A. Roseby, Gerhard Kuhn, Alastair G. Graham, Julian A. Dowdeswell

Marine Science Faculty Publications

Basal hydrological systems play an important role in controlling the dynamic behaviour of ice streams. Data showing their morphology and relationship to geological substrates beneath modern ice streams are, however, sparse and difficult to collect. We present new multibeam bathymetry data that make the Anvers-Hugo Trough west of the Antarctic Peninsula the most completely surveyed palaeo-ice stream pathway in Antarctica. The data reveal a diverse range of landforms, including streamlined features where there was fast flow in the palaeo-ice stream, channels eroded by flow of subglacial water, and compelling evidence of palaeo-ice stream shear margin locations. We interpret landforms as …

Ocean colour is recognised as an Essential Climate Variable (ECV) by the Global Climate Observing System (GCOS); and spectrally-resolved water-leaving radiances (or remote-sensing reflectances) in the visible domain, and chlorophyll-a concentration are identified as required ECV products. Time series of the products at the global scale and at high spatial resolution, derived from ocean-colour data, are key to studying the dynamics of phytoplankton at seasonal and inter-annual scales; their role in marine biogeochemistry; the global carbon cycle; the modulation of how phytoplankton distribute solar-induced heat in the upper layers of the ocean; and the response of the marine ecosystem to …

From Land To The Ocean: The Interplay Between Allochthonous And Autochthonous Contribution To Particles In Nepheloid Layers Of The Cariaco Basin, Venezuela, Laura Lorenzoni, Robert C. Thunell, Claudia R. Benitez-Nelson, Enrique Montes, Ramón Varela, Yrene Astor, Frank E. Muller-Karger

Marine Science Faculty Publications

Lithogenic sediment input to the Cariaco Basin on the eastern Venezuelan shelf is controlled by small mountainous rivers (SMRs). The Cariaco Basin is also an area of high phytoplankton productivity as a result of strong Trade Wind-driven coastal upwelling. Characterizing the sources that supply particulate organic carbon (POC) to the deep Cariaco Basin is important for interpreting the paleoclimate record stored in its sediments. We measured suspended POC in the four main rivers draining into the Caraiaco Basin, the Tuy, Unare, Neveri, and Manzanares, between September 2008 and September 2009 and conducted basin-wide oceanographic cruises in September 2008 (rainy season) …
