Spatial And Temporal Levels Of Microplastics In Tampa Bay Surface Waters, Laurinda Kinsley Mceachern Jan 2018

Spatial And Temporal Levels Of Microplastics In Tampa Bay Surface Waters, Laurinda Kinsley Mceachern

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

This study focused on collecting microplastics in Tampa Bay estuarine surface waters in order to identify temporal and spatial differences. While there have been many studies of microplastic contamination in the marine environment over the past decade, quantifying microplastics in urban estuaries is constrained. This study provides an understanding of the abundance, distribution, and composition of microplastics at twenty sites in Tampa Bay as well as four ancillary tributary stations. The objectives of the study were to identify how surrounding land use type, freshwater sources, seasonal changes in precipitation, and wastewater treatment plant discharge affect microplastic concentrations. Water samples were …

Determining Potential Uptake Pathways Of Persistent Organic Pollutants And Heavy Metals In Jobos Bay National Estuarine Research Reserve, Puerto Rico, Ashley Huber Jan 2018

Determining Potential Uptake Pathways Of Persistent Organic Pollutants And Heavy Metals In Jobos Bay National Estuarine Research Reserve, Puerto Rico, Ashley Huber

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

Fiddler Crab (U. rapax) tissue, mangrove tissue and sediment from crab burrows were collected in Jobos Bay National Estuarine Research Reserve, Puerto Rico, to quantitate Persistent Organic Pollutants (OCs, PCBs, PBDEs) and selected heavy metals (cadmium, barium, mercury, lead, vanadium, chromium, cobalt, nickel, copper, zinc, arsenic and selenium). Once quantified, the concentrations were applied to a bioconcentration factor equation to determine potential uptake pathways of the target analytes. Bioconcentration factors determined that fiddler crabs were the most efficient at concentrating OC pesticides, while mangroves were the most efficient at concentrating PCBs and heavy metals.

Soil Accumulation, Accretion, And Organic Carbon Burial Rates In Mangrove Soils Of The Lower Florida Keys: A Temporal And Spatial Analysis, Amanda R. Chappel Jan 2018

Soil Accumulation, Accretion, And Organic Carbon Burial Rates In Mangrove Soils Of The Lower Florida Keys: A Temporal And Spatial Analysis, Amanda R. Chappel

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

This study compared the temporal variability in rates of soil accumulation, accretion, and organic carbon (OC) burial from three sites in the Lower Florida Keys using two different radiometric dating techniques (210Pb, 14C). Comparison of these rates across various timescales (decadal, centurial, and millennial) permitted examination of temporal responses and drivers. Further, spatial variability was measured for these associated site rates. Differences in geographic location and site morphologies as predicted, were supported by spatial variability in all rates across sites with the exception of centurial rates of accretion. All rates were greater when assessed over shorter (e.g. decadal) timescales. The …

Impacts Of 40 Years Of Land Cover Change On Water Quality In Tampa Bay, Florida, Matthew J. Mccarthy, Frank E. Muller-Karger, Daniel Otis, Pablo Méndez-Lázaro Jan 2018

Impacts Of 40 Years Of Land Cover Change On Water Quality In Tampa Bay, Florida, Matthew J. Mccarthy, Frank E. Muller-Karger, Daniel Otis, Pablo Méndez-Lázaro

Marine Science Faculty Publications

Land cover changes in the Tampa Bay watershed (Florida) over the past four decades were examined along with precipitation and wind observations to help understand causes of long-term changes in turbidity and chlorophyll concentration within the Tampa Bay estuary. Water quality showed a statistically significant relationship to land cover fraction in the watershed compared to long-term precipitation or wind stress. Redundancy Analyses with Akaike’s Information Criterion and non-parametric multiple regressions determined that turbidity and chlorophyll concentration decreased bay-wide from 1974–2012 with increased developed land fraction (R2 > 0.75, p-value < 0.05). Various segments of the estuary showed different significant responses to developed land (R2 > 0.75, p-value < 0.05), agricultural land (R2 > 0.93, p-value < 0.02), bare land (R2 = 0.77, p-value = 0.001), and wind stress (R2 = 0.91, p-value = 0.04) at different times of year.

Intentional Cultural Destruction In Armed Conflicts, Zorana Knezevic Jan 2018

Intentional Cultural Destruction In Armed Conflicts, Zorana Knezevic

USF St. Petersburg campus Honors Program Theses (Undergraduate)

The intentional destruction of cultural sites during warfare provokes the question of why would armed actors invest significant resources into carrying out this activity, and what impact does it have in an anned conflict? This thesis identifies four main motivation types of intentional cultural destruction and how they may contribute to intensifYing a conflict. It hypothesizes that as intentional cultural destruction events increase in an armed conflict, so does the occurrence of battles, intensifYing conflict. To test its hypothesis, it utilizes the case studies of Syria and Yemen, conducting a S T A TA regression test for both. The Syrian …

Future Of Rural Transit, Jill Hough, Ali Rahim Taleqani Jan 2018

Future Of Rural Transit, Jill Hough, Ali Rahim Taleqani

Journal of Public Transportation

This paper provides a contemplative description of the future of rural public transportation. It considers emerging technologies along with their long-term implications and corresponding impacts on rural communities. The authors used their collective knowledge to identify key drivers of change in rural areas. As a result, the authors expect the future definition of rural areas to change and a new geographical classification to emerge. This classification is a continuum of population density gradient from highly populated urban areas to sparsely populated areas. The paper also suggests that automated vehicles and hologram telecommuting could dominate the U.S. transportation industry, even in …

Is It Time For A Public Transit Renaissance?: Navigating Travel Behavior, Technology, And Business Model Shifts In A Brave New World, Susan Shaheen, Adam Cohen Jan 2018

Is It Time For A Public Transit Renaissance?: Navigating Travel Behavior, Technology, And Business Model Shifts In A Brave New World, Susan Shaheen, Adam Cohen

Journal of Public Transportation

Travel behavior is undergoing a period of significant change in the United States. In 2016, public transit ridership fell in almost all major U.S. metropolitan regions. While Americans are still heavily dependent on the personal automobile for mobility, technological and societal changes are transforming how mobility is accomplished. This paper reviews the convergence of five trends leading to fundamental changes in public transportation: (1) changing generational behavior toward suburbanization and automobility; (2) new attitudes toward information communications technology; (3) shifting attitudes toward sharing and mobility on demand; (4) innovative alternatives to work and non-work travel; and (5) an increasing number …

Transit In The 2000s: Where Does It Stand And Where Is It Headed?, Michael Manville, Brian D. Taylor, Evelyn Blumenberg Jan 2018

Transit In The 2000s: Where Does It Stand And Where Is It Headed?, Michael Manville, Brian D. Taylor, Evelyn Blumenberg

Journal of Public Transportation

U.S. public transit has experienced something of a renaissance in the 2000s, with per capita service levels increasing nationwide and public investment growing even faster—particularly expenditures on rail transit. Despite this expansion, overall transit patronage has been relatively flat, and has declined significantly since 2014. What is behind these trends, and what do they portend for the future of transit? In this paper we consider three challenges shaping transit today and in the years ahead: (1) the asymmetry of transit supply and use make it especially vulnerable to changes and disruptions; (2) many of the factors that determine transit ridership, …

Satellite Sensor Requirements For Monitoring Essential Biodiversity Variables Of Coastal Ecosystems, Frank E. Muller-Karger Jan 2018

Satellite Sensor Requirements For Monitoring Essential Biodiversity Variables Of Coastal Ecosystems, Frank E. Muller-Karger

Marine Science Faculty Publications

The biodiversity and high productivity of coastal terrestrial and aquatic habitats are the foundation for important benefits to human societies around the world. These globally distributed habitats need frequent and broad systematic assessments, but field surveys only cover a small fraction of these areas. Satellite-based sensors can repeatedly record the visible and near-infrared reflectance spectra that contain the absorption, scattering, and fluorescence signatures of functional phytoplankton groups, colored dissolved matter, and particulate matter near the surface ocean, and of biologically structured habitats (floating and emergent vegetation, benthic habitats like coral, seagrass, and algae). These measures can be incorporated into Essential …

Unprecedented Diversity Of Ssdna Phages From The Family Microviridae Detected Within The Gut Of A Protochordate Model Organism (Ciona Robusta), Alexandria Creasy, Karyna Rosario, Brittany A. Leigh Jan 2018

Unprecedented Diversity Of Ssdna Phages From The Family Microviridae Detected Within The Gut Of A Protochordate Model Organism (Ciona Robusta), Alexandria Creasy, Karyna Rosario, Brittany A. Leigh

Marine Science Faculty Publications

Phages (viruses that infect bacteria) play important roles in the gut ecosystem through infection of bacterial hosts, yet the gut virome remains poorly characterized. Mammalian gut viromes are dominated by double-stranded DNA (dsDNA) phages belonging to the order Caudovirales and single-stranded DNA (ssDNA) phages belonging to the family Microviridae. Since the relative proportion of each of these phage groups appears to correlate with age and health status in humans, it is critical to understand both ssDNA and dsDNA phages in the gut. Building upon prior research describing dsDNA viruses in the gut of Ciona robusta, a marine invertebrate model system …

The Politics Of Organic Food Consumption, Recycling And Solar Power Use, Ana Maria Quintero Jan 2018

The Politics Of Organic Food Consumption, Recycling And Solar Power Use, Ana Maria Quintero

USF St. Petersburg campus Honors Program Theses (Undergraduate)

The Republican and Democratic parties have long had different agendas, and I want to see if there is any evidence to suggest that Republicans are less supportive of environmental issues while Democrats are more supportive of environmental issues.1 There are many environmental issues, but I am interested in organic food consumption, recycling and solar energy. This research contains a literature review of these environmental subjects, a review of the two major political party platforms, an online survey of more than 100 USFSP students, and an analysis of the survey results. The most important finding is that there is no relationship …

Flowstone Growth In Gournier River (Vercors, France): A Diachronic Landscape Analysis By 3d Modelling And Photo Draping, Kim Genuite, Yves Perrette, Stéphane Jaillet Dec 2017

Flowstone Growth In Gournier River (Vercors, France): A Diachronic Landscape Analysis By 3d Modelling And Photo Draping, Kim Genuite, Yves Perrette, Stéphane Jaillet

International Journal of Speleology

Calcite surface has been reported by cavers and scientists over the last decades. Here, we present a methodological work aimed at quantifying that growth. We suggest a method of draping old photographs of a part of the Gournier Cave onto a 3D model. This work relies on a collection of photographs taken by cavers. We have chosen to study a site for which the maximum number of photographs was available. The series of photographs over time makes it possible to overcome the limitation of calcite crust dating. The acquisition of the 3D model has been achieved using terrestrial LIDAR. Then, …

Groundwater Flood Hazards And Mechanisms In Lowland Karst Terrains, Owen Naughton, Ted Mccormack, Laurence Gill Dec 2017

Groundwater Flood Hazards And Mechanisms In Lowland Karst Terrains, Owen Naughton, Ted Mccormack, Laurence Gill

KIP Articles

The spatial and temporal complexities of flooding in karst terrains pose unique challenges in flood risk management. Lowland karst landscapes can be particularly susceptible to groundwater flooding due to a combination of low aquifer storage, high diffusivity and limited or absent surface drainage. Numerous notable groundwater flood events have been recorded in the Republic of Ireland throughout the twentieth century, but flooding during the winters of 2009 and 2015 was the most severe on record, causing widespread and prolonged disruption and damage to property and infrastructure. Effective flood risk management requires an understanding of the recharge, storage and transport mechanisms …

Assessing Preservation Priorities Of Caves And Karst Areas Using The Frequency Of Endemic Cave-Dwelling Species, Eugen Nitzu, Marius Vlaicu, Andrei Giurginca, Ioana N. Meleg, Ionut Popa, Augustin Nae, Ştefan Baba Dec 2017

Assessing Preservation Priorities Of Caves And Karst Areas Using The Frequency Of Endemic Cave-Dwelling Species, Eugen Nitzu, Marius Vlaicu, Andrei Giurginca, Ioana N. Meleg, Ionut Popa, Augustin Nae, Ştefan Baba

International Journal of Speleology

Endemic and rare species as bioindicators of habitat vulnerability were used to develop protection and management plans for biotope prioritization (mainly islands habitats, lava tubes or groundwaters). Due to their narrow distribution, the endemic species (species confined to a restricted geographic area) are more susceptible to ecological disequilibrium and habitat loss than the widespread ones. Consequently, endemics become endangered in the context of ecological disturbance caused by anthropogenic pressure, making them suitable candidates to assess environmental preservation needs. Taking into consideration that most of the stygobitic and troglobitic species are endemic and confined to specific karst areas, based on their …

Profiling The Immunome Of Little Brown Myotis Provides A Yardstick For Measuring The Genetic Response To White-Nose Syndrome, Michael E. Donaldson, Christina M. Davy, Craig K. R. Willis, Scott Mcburney, Allysia Park, Christopher J. Kyle

KIP Articles

White‐nose syndrome ( WNS ) has devastated populations of hibernating bats in eastern North America, leading to emergency conservation listings for several species including the previously ubiquitous little brown myotis ( Myotis lucifugus ). However, some bat populations near the epicenter of the WNS panzootic appear to be stabilizing after initial precipitous declines, which could reflect a selective immunogenetic sweep. To investigate the hypothesis that WNS exerts significant selection on the immunome of affected bat populations, we developed a novel, high‐throughput sequence capture assay targeting 138 adaptive, intrinsic, and innate immunity genes of putative adaptive significance, as well as their …

Wangari Maathai The Educator: Straddling Tradition And Modernity, Namulundah Florence

Journal of Global Education and Research

Wangari Muta Mary Jo Maathai’s (April 1, 1940 – September 25, 2011) public image highlights her nationality, her education both in and outside Kenya, her establishment of the Green Belt Movement (GBM) for which she received a Nobel Peace Prize in 2004, and her political activism. Advocates for female empowerment take solace in success stories like Maathai’s rise from a village girl to become a global icon of leadership. Yet, her mobility was more circumstantial than it was deliberate, and is inseparable from the uneasy compromise between the traditional gender roles of her youth with the critical consciousness nurtured in …

On The Loop Current Penetration Into The Gulf Of Mexico, Robert H. Weisberg, Yonggang Liu Dec 2017

On The Loop Current Penetration Into The Gulf Of Mexico, Robert H. Weisberg, Yonggang Liu

Marine Science Faculty Publications

The Gulf of Mexico Loop Current generally intrudes some distance into the Gulf of Mexico before shedding an anticyclonic eddy and retreating back to its more direct entry to exit pathway. The control of this aperiodic process remains only partially known. Here we describe the evolution of the Loop Current throughout the era of satellite altimetry, and offer a mechanistic hypothesis on Loop Current intrusion. As a complement to the known effects of Loop Current forcing on the west Florida shelf circulation, we argue that the west Florida shelf, in turn, impacts the Loop Current evolution. A Self-Organizing Map analysis …

International Journal of Speleology

In order to use speleothems in the reconstruction of past climate and environmental changes it is necessary to understand the environmental and hydrological processes that determine the physico-chemical conditions of carbonate precipitation and hence speleothem formation. Therefore, in this study an extended monitoring program was conducted in the Béke and Baradla caves located in the Aggtelek region (Northeastern Hungary). The studied caves are rich in speleothem and flowstone occurrences with great potential for paleoclimatology studies. The monitoring activity included measurements of atmospheric and cave temperatures, CO2 concentration in cave air, as well as chemical and isotopic compositions of water …
