Association Between Folate Levels And Preterm Birth In Tampa, Florida, Carolyn Heeraman Nov 2016

Trophic Ecology And Habitat Use Of Atlantic Tarpon (Megalops Atlanticus ), Benjamin Neal Kurth Nov 2016

Trophic Ecology And Habitat Use Of Atlantic Tarpon (Megalops Atlanticus ), Benjamin Neal Kurth

USF Tampa Graduate Theses and Dissertations

Fish can have complex life histories and use multiple habitats and resources throughout their life span. Consequently, their life histories are often poorly understood. The Atlantic Tarpon, Megalops atlanticus, is a large, typically migratory, elopomorph fish that is both ecologically and economically important. Atlantic Tarpon are under threat due to regional exploitation, loss of natal and juvenile habitat, poor water management, and offshore impacts. In addition, little is known about its lifelong habitat and resource use. In Chapter 1, I used stable isotope analysis of eye lens δ¹³C and δ¹⁵N values to explore patterns in …

Fish Names Variability Traces The Geo-Historical Dynamics Of Moroccan Fishermen Communities, Hicham Masski, Abdelaziz Ait Hammou Nov 2016

Fish Names Variability Traces The Geo-Historical Dynamics Of Moroccan Fishermen Communities, Hicham Masski, Abdelaziz Ait Hammou

Journal of Ecological Anthropology

Fish vernacular names in Morocco needs a structuring system. Though used widely, these names are highly variable and do not necessarily meet trade requirements. The 138 species considered in this study have 691 vernacular names and the vernacular names lists of the 16 study sites show large disparities. The most part of this variability is of linguistic origin coming from four geographic regions and thus cultural groups. Even if possible, the adoption of a unique standard, which is the goal of the national fisheries regulation authorities, might encounter resistance to its dissemination throughout fishermen and the local population.

Human-Associated Bacteroides Spp. And Human Polyomaviruses As Microbial Source Tracking Markers In Hawaii, Marek Kirs, Roberto A Caffaro-Filho, Mayee Wong, Valerie J. Harwood, Philip Moravcik, Roger S Fujioka

Integrative Biology Faculty and Staff Publications

Identification of sources of fecal contaminants is needed to (i) determine the health risk associated with recreational water use and (ii) implement appropriate management practices to mitigate this risk and protect the environment. This study evaluated human-associated Bacteroides spp. (HF183TaqMan) and human polyomavirus (HPyV) markers for host sensitivity and specificity using human and animal fecal samples collected in Hawaii. The decay rates of those markers and indicator bacteria were identified in marine and freshwater microcosms exposed and not exposed to sunlight, followed by field testing of the usability of the molecular markers. Both markers were strongly associated with sewage, although …

Contribution Of Epithelial Hypoxia Signaling To Pulmonary Fibrosis: Role Of Fak1 And Galectin-1 As Driver Molecules, Jaymin J. Kathiriya Oct 2016

Contribution Of Epithelial Hypoxia Signaling To Pulmonary Fibrosis: Role Of Fak1 And Galectin-1 As Driver Molecules, Jaymin J. Kathiriya

USF Tampa Graduate Theses and Dissertations

Idiopathic Pulmonary Fibrosis (IPF) is a deadly disease of unknown origin, which causes 80,000 deaths every year in the US and Europe combined. Unknown etiology and late diagnosis, combined with limited treatment options, contribute to a dismal survival rate of 3-5 years post diagnosis. Although molecular mechanisms underlying IPF pathogenesis and progression have been studied for over two decades, lack of in vivo models that recapitulate chronic, progressive, and irreversible nature of IPF have contributed to limited therapeutic success in clinical trials. Currently, only two drugs, Pirfenidone and Nintedanib, are approved for IPF treatment in the US, with their efficacy …

Cardiovascular Regulation By Kvβ1.1 Subunit, Jared Tur Oct 2016

Cardiovascular Regulation By Kvβ1.1 Subunit, Jared Tur

USF Tampa Graduate Theses and Dissertations

Heterologous expression systems such as COS-7 cells have demonstrated the profound effects of KCNAB1-3 or Kvβ1-3 proteins on voltage gated potassium channels (Kv) channels. Indeed, in the presence of these β-subunits transiently expressed Kv channels are often modulated in multiple ways. Kv channel membrane expression is often increased in the presence of β-subunits. In addition, non-inactivating Kv currents suddenly become fast-inactivating and fast-inactivating channels become even faster. While much research has demonstrated the profound effects the β-subunits in particular the Kvβ1 subunit have on transiently expressed Kv currents little to date is known of the physiological role it may play. …

Importance Of Forest Structure For Amphibian Occupancy In North-Central Florida: Comparisons Of Naturally Regenerated Forests With Planted Pine Stands, Christopher J E Haggerty Oct 2016

Importance Of Forest Structure For Amphibian Occupancy In North-Central Florida: Comparisons Of Naturally Regenerated Forests With Planted Pine Stands, Christopher J E Haggerty

USF Tampa Graduate Theses and Dissertations

Once dominant, longleaf pine forests of the southeastern United States have been modified by 97 percent, resulting in several animal species being listed as endangered and threatened. Pine plantation silviculture (tree plantings) now occupies half of the original longleaf range where several animal species of conservation concern have experienced recent local population declines. In North America, the accepted practice of pine plantations is to plant pines densely in rows for wood production. Given that land use is considered a primary local driver for the 30% of amphibian species currently at risk of extinction, and planted pine is predicted to expand …

The Skp1 Homologs Skr-1/2 Are Required For The Caenorhabditis Elegans Skn-1 Antioxidant/Detoxification Response Independently Of P38 Mapk., Cheng-Wei Wu, Andrew Deonarine, Aaron Przybysz, Kevin Strange, Keith P. Chloe

Molecular Biosciences Faculty Publications

SKN-1/Nrf are the primary antioxidant/detoxification response transcription factors in animals and they promote health and longevity in many contexts. SKN-1/Nrf are activated by a remarkably broad-range of natural and synthetic compounds and physiological conditions. Defining the signaling mechanisms that regulate SKN-1/Nrf activation provides insights into how cells coordinate responses to stress. Nrf2 in mammals is regulated in part by the redox sensor repressor protein named Keap1. In C. elegans, the p38 MAPK cascade in the intestine activates SKN-1 during oxidative stress by promoting its nuclear accumulation. Interestingly, we find variation in the kinetics of p38 MAPK activation and tissues with …

The Archaeopalynology Of Crystal River Site (8ci1), Citrus County, Florida, Kendal Jackson Oct 2016

The Archaeopalynology Of Crystal River Site (8ci1), Citrus County, Florida, Kendal Jackson

USF Tampa Graduate Theses and Dissertations

The Woodland-period (ca. 1000 B.C. to A.D. 1050) fisher-hunter-gatherers of the Crystal River drainage on Florida’s Big Bend Coast are well known among southeastern archaeologists for their elaborate shell mound architecture, maritime lifeway, and exotic exchange goods. Recent archaeological investigations at the Crystal River site have employed high-resolution topographic mapping, geophysical surveys, trench excavations, and coring to model the temporality of mound construction and occupation at the site; this work has set the stage for subsequent research focusing on community structure, resource extraction, and human-ecosystem dynamics. However, like many central and north peninsular Gulf Coast sites, our understanding of Crystal …

Feeding Patterns And Trophic Food Web Dynamics Of Armases Cinereum Across A Mangrove/Upland Ecotone, Erin Paige Kiskaddon Oct 2016

Feeding Patterns And Trophic Food Web Dynamics Of Armases Cinereum Across A Mangrove/Upland Ecotone, Erin Paige Kiskaddon

USF Tampa Graduate Theses and Dissertations

The feeding ecology of a common saltmarsh crab, Armases cinereum (Armases), was investigated to determine how habitat (mangrove vs. ecotone, natural mangrove vs. modified mangrove fringe) influenced this species’ feeding behavior and trophic ecology in its southwestern Florida, USA, distribution. In the laboratory, Armases’ preference for mangrove material was examined using leaves of three mangrove species (Avicennia germinans, Laguncularia racemosa, and Rhizophora mangle) and leaves of different degradation levels (fresh, senescent, and partially-decomposed). Leaf material from A. germinans was preferentially consumed over the other taxa at fresh and partially-decomposed levels of leaf decay. When Armases were …

Quantifying Trace Element And Isotope Fluxes At The Ocean-Sediment Boundary: A Review., William B. Homoky, Thomas Weber, William M. Berelson, Tim M. Conway, Gideon M. Henderson, Marco Van Hulten, Catherine Jeandel, Silke Severmann, Alessandro Tagliabue Oct 2016

Quantifying Trace Element And Isotope Fluxes At The Ocean-Sediment Boundary: A Review., William B. Homoky, Thomas Weber, William M. Berelson, Tim M. Conway, Gideon M. Henderson, Marco Van Hulten, Catherine Jeandel, Silke Severmann, Alessandro Tagliabue

Marine Science Faculty Publications

Quantifying fluxes of trace elements and their isotopes (TEIs) at the ocean's sediment-water boundary is a pre-eminent challenge to understand their role in the present, past and future ocean. There are multiple processes that drive the uptake and release of TEIs, and properties that determine their rates are unevenly distributed (e.g. sediment composition, redox conditions and (bio)physical dynamics). These factors complicate our efforts to find, measure and extrapolate TEI fluxes across ocean basins. GEOTRACES observations are unveiling the oceanic distributions of many TEIs for the first time. These data evidence the influence of the sediment-water boundary on many TEI cycles, …

Hearing In The Juvenile Green Sea Turtle (Chelonia Mydas): A Comparison Of Underwater And Aerial Hearing Using Auditory Evoked Potentials, Wendy E D Piniak, David A Mann, Craig A Harms, T Todd Jones, Scott A Eckert

Marine Science Faculty Publications

Sea turtles spend much of their life in aquatic environments, but critical portions of their life cycle, such as nesting and hatching, occur in terrestrial environments, suggesting that it may be important for them to detect sounds in both air and water. In this study we compared underwater and aerial hearing sensitivities in five juvenile green sea turtles (Chelonia mydas) by measuring auditory evoked potential responses to tone pip stimuli. Green sea turtles detected acoustic stimuli in both media, responding to underwater stimuli between 50 and 1600 Hz and aerial stimuli between 50 and 800 Hz, with maximum sensitivity between …

Processes Of Multibathyal Aragonite Undersaturation In The Arctic Ocean, Jonathan G. Wynn, Lisa Robbins, L. G. Anderson Oct 2016

Processes Of Multibathyal Aragonite Undersaturation In The Arctic Ocean, Jonathan G. Wynn, Lisa Robbins, L. G. Anderson

School of Geosciences Faculty and Staff Publications

During 3 years of study (2010–2012), the western Arctic Ocean was found to have unique aragonite saturation profiles with up to three distinct aragonite undersaturation zones. This complexity is produced as inflow of Atlantic‐derived and Pacific‐derived water masses mix with Arctic‐derived waters, which are further modified by physiochemical and biological processes. The shallowest aragonite undersaturation zone, from the surface to ∼30 m depth is characterized by relatively low alkalinity and other dissolved ions. Besides local influence of biological processes on aragonite undersaturation of shallow coastal waters, the nature of this zone is consistent with dilution by sea‐ice melt and invasion …

Chemical, Biological and Materials Engineering Faculty Publications

Analysis of individual cells at the subcellular level is important for understanding diseases and accelerating drug discovery. Nanoscale endoscopes allow minimally invasive probing of individual cell interiors. Several such instruments have been presented previously, but they are either too complex to fabricate or require sophisticated external detectors because of low signal collection efficiency. Here we present a nanoendoscope that can locally excite fluorescence in labelled cell organelles and collect the emitted signal for spectral analysis. Finite Difference Time Domain (FDTD) simulations have shown that with an optimized nanoendoscope taper profile, the light emission and collection was localized within ~100 nm. …

Dissolved Iron And Iron Isotopes In The Southeastern Pacific Ocean, Jessica N. Fitzsimmons, Tim M. Conway, Jong-Mi Lee, Richard Kayser, Kristen M. Thyng, Seth G. John, Edward A. Boyle

Marine Science Faculty Publications

The Southeast Pacific Ocean is a severely understudied yet dynamic region for trace metals such as iron, since it experiences steep redox and productivity gradients in upper waters and strong hydrothermal iron inputs to deep waters. In this study, we report the dissolved iron (dFe) distribution from seven stations and Fe isotope ratios (δ⁵⁶Fe) from three of these stations across a near‐zonal transect from 20 to 27°S. We found elevated dFe concentrations associated with the oxygen‐deficient zone (ODZ), with light δ⁵⁶Fe implicating porewater fluxes of reduced Fe. However, temporal dFe variability and rapid δ⁵⁶Fe …

Experimental Assessment Of Lionfish Removals To Mitigate Reef Fish Community Shifts On Northern Gulf Of Mexico Artificial Reefs, Kristin A. Dahl, William F. Patterson Iii, Richard A. Synder Oct 2016

Experimental Assessment Of Lionfish Removals To Mitigate Reef Fish Community Shifts On Northern Gulf Of Mexico Artificial Reefs, Kristin A. Dahl, William F. Patterson Iii, Richard A. Synder

C-IMAGE Publications

Substantial declines in reef fishes were observed at northern Gulf of Mexico artificial reef sites between 2009−2010 and 2011−2012, a period that bracketed the appearance of invasive lionfish in this ecosystem. Small demersal reef fishes, the predominant prey of lionfish in other systems, displayed the greatest declines. However, a confounding factor during this time was the Deepwater Horizon Oil Spill (DWH) in summer 2010. In some areas, targeted lionfish removals have been demonstrated to mitigate negative effects on native fishes. Therefore, we conducted a 2 yr experiment to examine the effectiveness and ecological benefits of targeted lionfish removals at artificial …

How Did The Deepwater Horizon Oil Spill Affect Coastal And Continental Shelf Ecosystems Of The Gulf Of Mexico?, Steven Murawski, John E. Fleeger, William F. Patterson Iii, Chuanmin Hu, Kendra L. Daly, Isabel C. Romero, Gerardo Toro-Farmer Sep 2016

How Did The Deepwater Horizon Oil Spill Affect Coastal And Continental Shelf Ecosystems Of The Gulf Of Mexico?, Steven Murawski, John E. Fleeger, William F. Patterson Iii, Chuanmin Hu, Kendra L. Daly, Isabel C. Romero, Gerardo Toro-Farmer

Marine Science Faculty Publications

The Deepwater Horizon (DWH) oil spill originated at the base of the continental shelf in the northern Gulf of Mexico (GoM), but large quantities of the oil were transported to the shelf (≤200 m water depth) and into coastal waters (herein defined as ≤15 km from the coast). Water-column effects were generally limited to the period of the ongoing oil releases, although, due to an extensive oil sedimentation event (“dirty blizzard”), effects on the benthos have the potential to be chronic, especially in soft sediments. Impacts on phytoplankton, zooplankton, and ichthyoplankton were relatively short-lived, and the abundance and species composition …

A Hybrid Method To Estimate Suspended Particle Sizes From Satellite Measurements Over Bohai Sea And Yellow Sea, Deyong Sun, Zhongfeng Qiu, Chuanmin Hu, Shengqiang Wang, Lin Wang, Lufei Zheng, Tian Peng, Yijun He

Marine Science Faculty Publications

Particle-size distribution (PSD), a measure of particle concentrations at different sizes, is of great importance to the understanding of many biogeochemical processes in coastal marine ecosystems. Here, a hybrid method, including analytical, semianalytical, and empirical steps, is developed to estimate PSD through the median diameter of suspended particles ( ). Four cruise surveys were conducted to measure optical scattering properties, particle concentrations, spectral reflectance, and particle-size distributions (obtained with a LISST instrument covering a size range of 2.5–500 μm) in coastal waters of Bohai Sea, Yellow Sea, and Jiangsu coastal region. Based on the Mie scattering theory, is closely related …

How Did The Deepwater Horizon Oil Spill Impact Deep-Sea Ecosystems?, Charles R. Fisher, Paul A. Montagna, Tracey T. Sutton

C-IMAGE Publications

Approximately 90% of the volume of the Gulf of Mexico is contained in water deeper than 200 m, a region where the Deepwater Horizon (DWH) blowout had more impact on ecosystems than any previous oil spill. The remoteness and relative inaccessibility of the deep sea makes documenting even acute impacts to the animals that live in this realm difficult. This article reviews Natural Resource Damage Assessment studies and follow-up work funded as part of the Gulf of Mexico Research Initiative that targeted deepwater pelagic and benthic fauna. Oil was incorporated into the pelagic food web, and a reduction in planktonic …
