Survey Of Endosymbionts In The Diaphorina Citri Metagenome And Assembly Of A Wolbachia Wdi Draft Genome, Surya Saha, Wayne B. Hunter, Justin Reese, J. Kent Morgan, Mizuri Marutani-Hert, Hong Huang, Magdalen Lindeberg

School of Information Faculty Publications

Diaphorina citri (Hemiptera: Psyllidae), the Asian citrus psyllid, is the insect vector of Ca. Liberibacter asiaticus, the causal agent of citrus greening disease. Sequencing of the D. citrimetagenome has been initiated to gain better understanding of the biology of this organism and the potential roles of its bacterial endosymbionts. To corroborate candidate endosymbionts previously identified by rDNA amplification, raw reads from the D. citri metagenome sequence were mapped to reference genome sequences. Results of the read mapping provided the most support for Wolbachia and an enteric bacterium most similar to Salmonella. Wolbachia-derived reads were extracted using …

Phytoplankton Responses To Atmospheric Metal Deposition In The Coastal And Open-Ocean Sargasso Sea, Katherine Mackey, Kristen N. Buck, John Casey, Abigail Cid, Michael Lomas, Yoshiki Sohrin, Adina Paytan

Marine Science Faculty Publications

This study investigated the impact of atmospheric metal deposition on natural phytoplankton communities at open-ocean and coastal sites in the Sargasso Sea during the spring bloom. Locally collected aerosols with different metal contents were added to natural phytoplankton assemblages from each site, and changes in nitrate, dissolved metal concentration, and phytoplankton abundance and carbon content were monitored. Addition of aerosol doubled the concentrations of cadmium (Cd), cobalt (Co), copper (Cu), iron (Fe), manganese (Mn), and nickel (Ni) in the incubation water. Over the 3-day experiments, greater drawdown of dissolved metals occurred in the open ocean water, whereas little metal drawdown …

Present And Potential Future Distribution Of Common Vampire Bats In The Americas And The Associated Risk To Cattle, Dana N. Lee, Monica Papeş, Ronald A. Van Den Bessche

KIP Articles

Success of the cattle industry in Latin America is impeded by the common vampire bat, Desmodus rotundus, through decreases in milk production and mass gain and increased risk of secondary infection and rabies. We used ecological niche modeling to predict the current potential distribution of D. rotundus and the future distribution of the species for the years 2030, 2050, and 2080 based on the A2, A1B, and B1 climate scenarios from the Intergovernmental Panel on Climate Change. We then combined the present day potential distribution with cattle density estimates to identify areas where cattle are at higher risk for the …

Dha Derivatives Of Fish Oil As Dietary Supplements: A Nutrition-Based Drug Discovery Approach For Therapies To Prevent Metabolic Cardiotoxicity, Yonggang Ma, Merry L. Lindsey, Ganesh V. Halade

Internal Medicine Faculty Publications

Introduction: During the early 1970s, Danish physicians Jorn Dyerberg and colleagues observed that Greenland Eskimos consuming fatty fishes exhibited low incidences of heart disease. Fish oil is now one of the most commonly consumed dietary supplements. In 2004, concentrated fish oil was approved as a drug by the FDA for the treatment of hyperlipidemia. Fish oil contains two major omega-3 fatty acids: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). With advancements in lipid concentration and purification techniques, EPA- or DHA-enriched products are now commercially available, and the availability of these components in isolation allows their individual effects to be examined. …

State-Induced Famine And Penal Starvation In North Korea, Rhoda E. Howard-Hassmann

Genocide Studies and Prevention: An International Journal

This article discusses North Korea as a case of state-induced famine, or faminogenesis. A famine from 1994 to 2000 killed 3–5% of North Korea’s population, and mass hunger reappeared in 2010– 2012, despite reforms meant to address the shortage of food. In addition, a prison population of about 200,000 people is systematically deprived of food; this might be considered penal starvation. There seems little recourse under international law to punish the perpetrators of state-induced fam- ine and penal starvation. State-induced famine does, however, fit some of the criteria of genocide in the United Nations Convention against Genocide, and could also …

Relationships Of Heat Stress Levels To Heat-Related Disorders And Acute Injury During Deepwater Horizon Cleanup Operations, Michael H. Hiles

USF Tampa Graduate Theses and Dissertations

Outdoor workers are often subjected to thermal conditions beyond the comfort zone, but to what degree do such conditions affect the health and safety of those workers is still a matter requiring further investigation. The purpose of this study is to examine the relationship between thermal conditions and (1) heat-related disorders and (2) acute injuries using injury and illness data collected during the BP Deepwater Horizon clean-up operations. Over an eleven month period, 5,485 cases were identified as either heat-related or an acute injury (incident type) and further divided by severity. Daily weather data were used to estimate the wet …

A Mother's Love: A Narrative Analysis Of Food Advertisements In An African American Targeted Women's Magazine, Janine Danielle Beahm

USF Tampa Graduate Theses and Dissertations

This thesis examines how food advertisers contributed to the cultural identity of the "good mother" in the 1990s and 2000s. It expands on previous research that investigated traditional gender ideologies in food advertisements by narrowing in on the specific stories presented to African American women. It highlights a time when advertisers were responding to the demands of African American activists to recognize the African American consumer, and depict African American characters in a positive light. A narrative method of inquiry is utilized to deconstruct the stories in 117 food advertisements running in Essence magazine (an African American targeted women's magazine) …

Investigating The Status Of Early Numeracy Skills In Bilingual Dual Language Learner Latino Children Attending Head Start And The Association With Parent Demographic Characteristics, Chavely Lissette Iglesias

USF Tampa Graduate Theses and Dissertations

Research on mathematics achievement has become increasingly important with today's technological advances and demand for specialized knowledge. Though there is much literature regarding mathematics achievement in monolingual speakers, little is known regarding the mathematical abilities of Dual Language Learner (DLL) Latino children. This study examined the early numeracy skills in English and Spanish of 132 DLL Latino children attending Head Start programs in five counties across Florida. Relationships and differences among their performance in both languages were examined, along with the contribution of specific parent demographic variables to math achievement. Findings indicated that DLL Latino Head Start children's performance on …

Availability And Quality Of Vegetation Affects Reproduction Of The Gopher Tortoise (Gopherus Polyphemus) In Improved Pastures, Anna Louise Hathaway

USF Tampa Graduate Theses and Dissertations

As part of a state-funded Gopher Tortoise (Gopherus polyphemus Daudin) translocation project, I monitored actively grazed improved pastures to determine if they could serve as suitable recipient sites for the threatened Gopher Tortoise displaced by human development. For cattle ranches to be considered suitable recipient sites females must be able to acquire sufficient energy to produce a clutch of viable eggs, and sufficiently high quality vegetation must be available to support juvenile recruitment into the population. Vegetation surveys were conducted to determine the composition and percent cover of plant species, especially those containing high amounts of nutrients, specifically nitrogen. Resident …

Butterbeer, Cauldron Cakes, And Fizzing Whizzbees: Food In J.K. Rowling's Harry Potter Series, Leisa Anne Clark

USF Tampa Graduate Theses and Dissertations

ABSTRACTThis thesis situates the Harry Potter books into the greater body of food studies and into the extant children's literary tradition through an examination of how food can be used to understand cultural identity. Food is a biological need, but because we have created social rules and rituals around food consumption and sharing, there is more to eating than simple nutritional value. The Harry Potter series is as much about overcoming childhood adversity, and good versus evil, as it is about magic, and food in the Harry Potter series is both abundant and relevant to the narrative, context, and themes …

The Complex Origin Of Astyanax Cavefish, Joshua B. Gross

KIP Articles

Background The loss of phenotypic characters is a common feature of evolution. Cave organisms provide excellent models for investigating the underlying patterns and processes governing the evolutionary loss of phenotypic traits. The blind Mexican cavefish, Astyanax mexicanus, represents a particularly strong model for both developmental and genetic analyses as these fish can be raised in the laboratory and hybridized with conspecific surface form counterparts to produce large F2 pedigrees. As studies have begun to illuminate the genetic bases for trait evolution in these cavefish, it has become increasingly important to understand these phenotypic changes within the context of cavefish origins. …

Learning Without Being Taught: A Look At How Schools, The Home And The Neighborhood Influence "Race" Conceptualization, Owen Christopher Gaither

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Where do we get our ideas about the concept of `race'? The conceptualization of `race' has long been a topic of interest in the social sciences and society in general. The word `race' has been used and defined in different ways and different purposes throughout U.S. history. The definition of `race' therefore is arbitrary, changing according to the situation, but the consequences of how the word `race' is used are concrete and effect peoples lives daily. This research, in accord with much of the literature on the topic, shows that public schools play a major role in the conceptualization …
