Spatially-Weighted Ethnic Density And Residential Segregation: Effects On Health Status Among Older Mexican Americans, Sung Han Rhew

USF Tampa Graduate Theses and Dissertations

Research suggests that living in communities with high densities of persons from their own ethnic group improves the overall health of older Mexican Americans. One hypothesis is that residing in high ethnic density areas allows characteristics of Mexican culture such as strong social ties and social cohesion, to have a beneficial effect. The majority of investigations focused on ethnic density effects, however, have utilized relatively loose interpretations of what constitutes the appropriate social-geographic area to be studied. Moreover it is not clear how certain dimensions of residential segregation are protective or harmful toward health, particularly when measuring ethnic residential segregation …

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 …

Isotopic Incorporation Rates And Discrimination Factors In Mantis Shrimp Crustaceans., Maya Devries, Carlos Del Rio, Tate Tunstall, Todd Dawson

Faculty Publications, Biological Sciences

Stable isotope analysis has provided insights into the trophic ecology of a wide diversity of animals. Knowledge about isotopic incorporation rates and isotopic discrimination between the consumer and its diet for different tissue types is essential for interpreting stable isotope data, but these parameters remain understudied in many animal taxa and particularly in aquatic invertebrates. We performed a 292-day diet shift experiment on 92 individuals of the predatory mantis shrimp, Neogonodactylus bredini, to quantify carbon and nitrogen incorporation rates and isotope discrimination factors in muscle and hemolymph tissues. Average isotopic discrimination factors between mantis shrimp muscle and the new diet …

Growth And Nickel Uptake By Serpentine And Non-Serpentine Populations Of Fimbristylis Ovata (Cyperaceae) From Sri Lanka, P. K. D. Chathuranga, S. K. A. T. Dharmasena, Nishanta Rajakaruna, M.C.M. Iqbal

Biological Sciences

Compared with serpentine floras of Southeast Asia, the serpentine vegetation of Sri Lanka is impoverished in regard to serpentine endemics and nickel hyperaccumulators. All species so far documented from the serpentine outcrops of Sri Lanka also have non-serpentine populations; it is unclear whether the serpentine populations are physiologically distinct and deserve ecotypic recognition. We conducted a preliminary study to examine whether serpentine and non-serpentine populations of Fimbristylis ovata represent locally adapted ecotypes by investigating their growth and potential for nickel uptake and tolerance under greenhouse conditions. Although both populations of F. ovata showed a similar growth pattern in serpentine soil …

A month into the new school year, a secondgrade teacher stopped me in the hallway to ask about Kyle, one of my former Reading Recovery students. The teacher said he was in the lowest reading group, and she didn’t see how his Reading Recovery intervention could have been discontinued last year. I couldn’t understand it; he finished strong at the end of the year, reading a level 18 text with ease. I tried to explain this, but she looked skeptical. I told her I would work with him in a booster group to get him back up to speed, but …

A Descriptive Analysis Of Gastric Cancer In Alaska, Fabrice Evengue

Student Projects for Graduate Degrees

Gastric cancer or stomach cancer represents a major public health problem in the contiguous United States and in Alaska. Stomach cancer is the fourth most common malignancy and the second most common cause of cancer-related deaths throughout the world. A retrospective study of gastric cancer cases from 1996 to 2011 was undertaken and data were extracted from the Alaska Cancer Registry where cases are consistently recorded and centralized. Data were analyzed using the National Cancer Institute’s SEER* Stat statistical software (version 8.1.5). The goal of the project was to provide a detailed epidemiologic descriptive analysis of gastric cancer to better …

Documenting Annual Differences In Vegetation Cover, Height And Diversity Near Barrow, Alaska, Timothy Frederick Botting

Masters Theses

Vegetation in the Arctic has been shown to respond to climate change. Documented changes have the potential to result in numerous ecosystem consequences. Therefore, understanding vegetation change is of great importance. This study documents changes in tundra vegetation with a focus on understanding the influence of annual differences in weather. Vegetation was sampled using a point frame method on 98 1-m² plots in 2010 and 2013 near Barrow, Alaska. A subset of 30 of these plots was also sampled in 2012 and 2014. Plant encounters were identified to species and grouped into one of the following functional groups: bryophytes, …

The Ecological Significance Of Emerging Deltas In Regulated Rivers, Malia A. Volke, Michael L. Scott, W. Carter Johnson, Mark Dixon

Natural Resource Management Faculty Publications

Sedimentary deltas forming in the world’s regulated rivers are a glaring gap in our knowledge of dammed riverine ecosystems. Basic ecological information is needed to inform the current debate about whether deltas should be retained and managed to gain ecosystem services lost under reservoirs or whether they should be partially removed to improve flow conveyance and to resupply sediment-starved reaches below dams. An examination of nine deltas on the heavily regulated upper and middle Missouri River showed the following: The sizes, dynamics, and biotic communities vary widely across deltas; riparian forest has established on portions of most deltas; the current …

Harvest Demographics Of Temperate-Breeding Canada Geese In South Dakota, 1967–1995, Jeffrey S. Gleason, Jonathan A. Jenks, David E. Naugle, Paul W. Mammenga, Spencer J. Vaa, Jennifer M. Pritchett

Natural Resource Management Faculty Publications

In South Dakota, breeding giant Canada geese (Branta canadensis maxima) have increased substantially, and harvest management strategies have been implemented to maximize hunting opportunity (e.g., special early-September seasons) on local, as well as molt-migrant giant Canada geese (B. c. interior) while still protecting lesser abundant Arcticbreeding Canada geese and cackling geese (e.g., B. hutchinsii, B. minima). Information on important parameters, such as survival and recovery rates, are generally lacking for giant Canada geese in the northern Great Plains. Patterns in Canada goose band recoveries can provide insight into the distribution, chronology, and harvest pressures to which a given goose population …

Fauna Census Of Intertidal Cliffs, Mangapwani, Zanzibar, Emily Jankowski

Independent Study Project (ISP) Collection

Due to their extreme variations in condition over the course of a day, intertidal zones are challenging environments. Organisms that live there must be prepared to cope with both exposure and submersion, not to mention the temperature variations that accompany these conditions. The differing tolerances and adaptations of various organisms to these conditions generally cause patterns of vertical zonation to occur in the intertidal zone, especially when the shore is steep and rocky. Understanding the ecology of shore environments is important to future conservation and management efforts. This study was conducted on a beach in Mangapwani, Zanzibar at at 6˚ …

The Industrial Impact On Wetlands In Jinja And The Nexus Of Industry, Wetlands, And Community (A Rights-Based Sustainable Development Approach), Ranger Ruffins

Independent Study Project (ISP) Collection

Uganda is a beautiful country filled with an extensive amount of natural resources, one of the most profound being wetlands. It is said that these wetlands are a crucial source of food and water for almost 3 million people (NEMA, 2012 and Oguttu et.al, 2008). They also provide many more invaluable socioeconomic benefits for the country. As Uganda experiences increasing development as well as a rapidly increasing population, the wetlands become increasingly necessary, at the same time they become increasingly threatened. It is written in the 1995 Ugandan constitution that Ugandan policy is aimed at ensuring sustainable development for the …

Association Between Air Temperature And Heart Disease Death Rates In Georgia Counties, John Hart

Journal of the Georgia Public Health Association

Background: In this ecological study, global warming theory was tested on a local level, in Georgia. The hypothesis was that warmer counties would be associated with higher death rates.

Methods: Heart disease death rates (HDDR) for 2008-2010 by Georgia county were compared to air temperature, also by county for the same years. Three race categories for HDDR were studied: black, white, and all races. Since there is evidence that living at higher land elevations provides a protective effect against heart disease, land elevation by county was included as a second predictor.

Results: Correlation analyses revealed low strength, statistically significant correlations …

Is Radon Emission In Caves Causing Deletions In Satellite Dna Sequences Of Cave-Dwelling Crickets?, Giuliana Allegrucci, Valerio Sbordoni, Donatella Cesaroni

KIP Articles

The most stable isotope of radon, 222Rn, represents the major source of natural radioactivity in confined environments such as mines, caves and houses. In this study, we explored the possible radon-related effects on the genome of Dolichopoda cave crickets (Orthoptera, Rhaphidophoridae) sampled in caves with different concentrations of radon. We analyzed specimens from ten populations belonging to two genetically closely related species, D. geniculata and D. laetitiae, and explored the possible association between the radioactivity dose and the level of genetic polymorphism in a specific family of satellite DNA (pDo500 satDNA). Radon concentration in the analyzed caves ranged from 221 …

The Status Of Fishes In The Missouri River, Nebraska: Blue Sucker Cycleptus Elongatus, Kirk D. Steffensen, Sam Stukel, Dane A. Shuman

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Blue Sucker Cycleptus elongatus are a large-bodied, benthic fish that are considered an indicator species for riverine health. A combination of historic commercial fishing and anthropogenic modifications to riverine habitat led to blue suckers being listed as a candidate species for the federal threatened or endangered species list in 1993. However, they were never designated a federally protected species. Locally, Blue Suckers are currently listed as a Nebraska Natural Legacy Project’s Tier 1 species but population changes and trends have not been quantified. Therefore, the objective of this paper was to evaluate the current population status of Blue Sucker in …

Publications and Research

Background
As climate change increases the frequency and intensity of extreme heat events researchers and public health officials must work towards understanding the causes and outcomes of heat-related morbidity and mortality. While there have been many studies on both heatrelated illness (HRI), there are fewer on heat-related morbidity than on heatrelated mortality.

Objective
To identify individual and environmental risk factors for hospitalizations and document patterns of household cooling.

Methods
We performed a pooled cross-sectional analysis of secondary U.S. data, the Nationwide Inpatient Sample. Risk ratios were calculated from multivariable models to identify risk factors for hospitalizations. Hierarchical modeling was also …

Development Modeling Of Lucilia Sericata (Diptera: Calliphoridae), Amanda Roe, Leon G. Higley

School of Natural Resources: Faculty Publications

The relationship between insect development and temperature has been well established and has a wide range of uses, including the use of blow flies for postmortem (PMI) interval estimations in death investigations. To use insects in estimating PMI, we must be able to determine the insect age at the time of discovery and backtrack to time of oviposition. Unfortunately, existing development models of forensically important insects are only linear approximations and do not take into account the curvilinear properties experienced at extreme temperatures. A series of experiments were conducted with Lucilia sericata, a forensically important blow fly species, that met …

Microbial Iron Mats At The Mid-Atlantic Ridge And Evidence That Zetaproteobacteria May Be Restricted To Iron-Oxidizing Marine Systems, Jarrod J. Scott, John A. Breier, George W. Luther Iii, David Emerson

School of Earth, Environmental, & Marine Sciences Faculty Publications

Chemolithoautotrophic iron-oxidizing bacteria play an essential role in the global iron cycle. Thus far, the majority of marine iron-oxidizing bacteria have been identified as Zetaproteobacteria, a novel class within the phylum Proteobacteria. Marine iron-oxidizing microbial communities have been found associated with volcanically active seamounts, crustal spreading centers, and coastal waters. However, little is known about the presence and diversity of iron-oxidizing communities at hydrothermal systems along the slow crustal spreading center of the Mid-Atlantic Ridge. From October to November 2012, samples were collected from rust-colored mats at three well-known hydrothermal vent systems on the Mid-Atlantic Ridge (Rainbow, Trans-Atlantic Geotraverse, and …

The Entrance As A Complex Ecotone In A Neotropical Cave, Xavier Prous, Rodrigo Lopes Ferreira, Claudia Maria Jacobi

International Journal of Speleology

Cave entrances are transition zones with intermediate characteristics between epigean environments, which bear lower environmental stability, and hypogean environments, with lower food resources. Associated to these interfaces there is a specific community, capable of exploiting its unique and intermediate characteristics. This work investigated this community in a Brazilian limnestone cave, identifying its arthropod species composition and spatial distribution, and exploring its relationships with climatic and structural environment characteristics and trophic relations. An ecotone zone was identified, with 55 species found only in the ecotone, 49 species were shared with the epigean community, 37 species with the hypogean community, and 14 …

Recurrent Evolution Of Melanism In South American Felids, Alexsandra Schneider, Corneliu Henegar, Kenneth Day, Devin Absher, Constanza Napolitano, Leandro Silveira, Victor A. David, Stephen J. O'Brien, Marilyn Menotti-Raymond, Gregory S. Barsh, Eduardo Eizirik

Biology Faculty Articles

Morphological variation in natural populations is a genomic test bed for studying the interface between molecular evolution and population genetics, but some of the most interesting questions involve non-model organisms that lack well annotated reference genomes. Many felid species exhibit polymorphism for melanism but the relative roles played by genetic drift, natural selection, and interspecies hybridization remain uncertain. We identify mutations of Agouti signaling protein (ASIP) or the Melanocortin 1 receptor (MC1R) as independent causes of melanism in three closely related South American species: the pampas cat (Leopardus colocolo), the kodkod (Leopardus guigna), and Geoffroy’s cat …

Sulfidic Spring In The Gypsum Karst System Of Monte Conca (Italy): Chemistry And Microbiological Evidences, Marianna Messina, Tiziana Grech, Fiorenzo Fiorenza, Alessandro Marlettta, Pietro Valenti, Salvatore Petralia

International Journal of Speleology

Monte Conca Cave is a karst system placed in Messinian evaporites, consisting of an active cave and a resurgence located on the massif of Monte Conca, Campofranco within the "Riserva Naturale Integrale di Monte Conca". A sulfidic spring is located in the terminal gallery of the cave. To characterize the physical and chemical parameters of the Monte Conca cave and of the sulfidic spring, air temperature, relative humidity, water pH, and concentrations of dissolved sulfides, nitrates and sulfates were monitored. The high sulfide consumption rate in the sulfidic spring, evaluated by a kinetic study, suggests that biotic consumption is dominant. …
