Undergraduate research is one of the five areas of opportunity, (along with internships, service, leadership, and international experience), which students are encouraged to participate in during their undergraduate career. Once again, a record number of undergraduate researchers will present posters this year. Three hundred and twenty-four posters and four performances will be presented. This group represents all UF colleges. Thirty-five UF undergraduate researchers representing eight colleges have presented their work at professional conferences from Louisiana to Oregon, and Massachusetts to California. This year CUR sponsored 44 students who presented their research work at the 8th Annual Florida Undergraduate Research Conference at Eastern Florida College. Additionally, over 2000 students have taken advantage of the opportunity to register for the research courses offered by each College. Each of these students has benefitted from mentoring provided by exceptional faculty and graduate student researchers. We thank them for their efforts on behalf of these students. Faculty mentors are listed following the abstracts. We encourage you to visit the presentations, talk with the students about their research, and read the collection of abstracts.

An expression for the characteristic dimension of the rectangular electrode was found that can be used to estimate the frequency associated with geometry-induced frequency dispersion. These results may serve to guide the design of rectangular-shaped sensors that employ impedance measurements. PRESENTER(S): Melendez, Laura AUTHOR(S): Laura Melendez, Eden Schoepflin, Dr. Jocelyn Wider FACULTY MENTOR: Jocelyn Widmer Impact of Youth Engagement in Technologically Based Water Well Surveying: Punta Cana, Dominican Republic Efforts to address issues in resource-challenged contexts can often be disconnected from the realities on the ground. This is true for Verón, a sprawling, informal, urban area in the Punta Cana touristic region of the Dominican Republic. Despite good intentions, past projects in the region have been disconnected from social, cultural, and environmental dynamics of the community impacted. To eliminate this disconnection, we took an interdisciplinary approach towards sustainable development. By capturing the spatial distribution of water points and their characteristics through youth engagement objectives, we promoted a foundation for development that promotes local participation in decision -making and regional policy development. With a team of local youth, this research inventoried household water point in Verón and captured GPS points, photos, and general characteristics associated with each water point. A training certification program was developed within cultural contexts in which youth participants were trained to conduct water wells surveys. Youth were observed throughout this certification process to understand how transferable skills of data collection could be beneficial for future educational or employment opportunities. A base layer of water-related infrastructure in the region was complied from water points, to conduct appropriate spatial analysis, and communicate data to key decision -makers in the region. 4 PRESENTER(S): Secades, Marissa AUTHOR(S): Marissa Secades FACULTY MENTOR: Barbara Mennel Culture Through Color Perception in "West Side Story" My project focuses on the use of color theory to clearly characterize members of rival ethnic gangs in the 1961 film adaptation of "West Side Story", which captured audiences with its groundbreaking innovation in choreography and music and earned praise from critics for delving into issues like immigration and gang -related violence. While much of the existing research focuses on the film’s references to vying cultures made explicitly through song and dance, this research instead focuses on the non -verbal representations of these cultures that are expressed through color in the film. By studying its iconic art direction and investigating audiences’ subsequent perceptions of characters, I argue that the colors featured in the costume designs are used to denote a culturally-charged power structure between the Jets and the Sharks. Based on close examination of various designs, its overall color palette, and published scholarship, I conclude that "West Side Story”'s non-verbal references are uniquely dangerous to its explicit references, as they subliminally promote harmful stereotypes and suggest that gang violence brings life to an otherwise drab city. Studying the connection between color theory and culture ultimately illuminates the historical roots of society's perceptions of colors and their seemingly inherent associations to certain traits. PRESENTER(S): Swanson, Samuel AUTHOR(S): Samuel Swanson FACULTY MENTOR: Maia Martcheva A Simple Epidemiological Model for Human Immunodeficiency Virus Based On Erlang's Method of Stages This research is to select an epidemiological model for HIV that uses few parameters while fitting the world prevalence and death data well. Here we consider a set of models based on Erlang's method of stages, including some with and some without social distancing. The use of stages is supported by biological studies which suggest that HIV passes through stages in each individual, although the exact number is not known. This set of models represents such stages by using a successive number of classes. To perform model selection, we compute R0 and use it to estimate initial values of the parameters in this model. We run thousands of iterations of a Nelder -Mead simplex search algorithm to determine the optimal values of parameters for each model and the error associated with each model. These errors are used to compute AICc values and then the AICc values are compared to select the most likely model. The selected model from this experiment contains the social distancing term as well as four infected classes/stages. We then perform identiability analysis and determine that the "true values" of the parameters for this model are uniquely determinable based on the data points. 5 PRESENTER(S): Zhang, Terrence AUTHOR(S): Terrence (Yidong) Zhang FACULTY MENTOR: Mahendrarajah Nimalendran Predicting Credit Default Swap (CDS) Returns with Machine Learning Credit Default Swaps (“CDS”) are contracts that insure one party against default in an underlying financial instrument, usually a bond. Therefore, the price of CDS reflects the perceived risk of default in an underlying financial instrument. This project applied Support Vector Machines (“SVMs”) to the prediction of CDS price changes for several individual companies across time. Previous research applying SVMs to predicting CDS prices used historical CDS prices as model inputs. This project proposed and applied several new input variables. Tests over a period of several years, across a group of CDS time-series, indicate that a combined model which uses the new input variables in addition to historical CDS price changes outperforms models that only use historical CDS price changes. 6 UF College of the Arts School of Theatre & Dance University Scholars Performances PRESENTER(S): Baeta, Sabrina AUTHOR(S): Sabrina Baeta FACULTY MENTOR: Brenda Smith The

  • Does Access to Opuntia Humifusa Cactus Seeds Affect Egg Production in the Cactus Bug, Narnia Femorata (Hemiptera: Coreidae)?
    Does access to Opuntia humifusa cactus seeds affect egg production in the cactus bug, Narnia femorata (Hemiptera: Coreidae)? Anthony Riggio and Christine Miller University of Florida Department of Entomology and Nematology Abstract Animals face challenges in acquiring the resources necessary for their survival and reproduction. Our study considered Narnia femorata, a species of true-bug which feeds on the fruits of the Opuntia humifusa cactus. We sought to determine if N. femorata is feeding on the seeds contained within O. humifusa cactus fruits, information which could help explain environmental and social factors affecting the life histories of true bugs. We compared the egg production of N. femorata breeding pairs provided O. humifusa fruits with the seeds intact with breeding pairs provided O. humifusa cactus fruits where the seeds were physically removed. We found that significantly more eggs were laid in the presence of fruit, as predicted from the results of prior studies showing the importance of proteins and lipids to egg production in insects. Our results suggest that N. femorata feeding on cactus fruit seeds will produce more eggs than those which do not. Therefore we posit that O. cactus fruit seeds are an important food resource for Narnia femorata because the seeds persist within the fruits throughout much of the annual growing season and contain higher concentrations of proteins and lipids relative to other O. cactus tissues. Keywords: Narnia femorata, Opuntia, Cactus, Reproduction Introduction Animals are not always able to acquire the resources necessary to maximize their survival and reproduction (Batzli & Lesieutre 1991). There are food resources present within environments that can enhance the fitness of those animals that selectively feed on them (Batzli & Lesieutre 1991).

  • Crapemyrtle Bark Scale Acanthococcus Lagerstroemiae Kuwana (Hemiptera: Eriococcidae): Analysis of Factors Influencing Infestation and Control
    CRAPEMYRTLE BARK SCALE ACANTHOCOCCUS LAGERSTROEMIAE KUWANA (HEMIPTERA: ERIOCOCCIDAE): ANALYSIS OF FACTORS INFLUENCING INFESTATION AND CONTROL A Thesis by KYLE ANDREW GILDER Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE Chair of Committee, Kevin M. Heinz Co-Chair of Committee, Mengmeng Gu Committee Members, Mike Merchant Head of Department, Phillip Kaufman December 2020 Major Subject: Entomology Copyright 2020 Kyle Andrew Gilder ABSTRACT Crapemyrtle bark scale, Acanthococcus lagerstroemiae (Kuwana), a new non-native pest from Asia first discovered in the U.S. in 2004 has now been reported in 14 states. The scale jeopardizes the future of crapemyrtles use as a popular ornamental landscape tree in the U.S. Management of this pest will likely include biological strategies. Before such strategies can be implemented it is important to examine relative abundances and distributions of arthropod species associated with the scale in the geographic area targeted for biological control. In the first objective, surveys of crapemyrtle ecology from two varietal groups of crapemyrtle trees (Lagerstroemia spp.) were undertaken in Tarrant and Brazos counties across six consecutive seasons in 2018 – 2019. A rich arthropod community was discovered. The most common predators were spiders, coccinellids, and chrysopids. Insects in the families Eriococcidae, Aphididae, and Thripidae were common herbivores on Lagerstroemia spp. Numerous phytophagous and mycophagous mites were also collected. These herbivores constitute a reservoir of alternative prey for generalist predators that may also feed on A. lagerstroemiae. A food web was constructed to illustrate direct and indirect effects of the predator community on A.

Biodiversity Data Journal 5: e13067. https://doi.org/10.3897/BDJ.5.e13067 Abstract Background Coreidae bugs are mostly sap-sucking insects feeding on a variety of plants. Despite their abundance and economic importance in Honduras there is little information on the species, their distribution and affected crops. Since knowledge of pest species allows for better management of crops, we aimed to document the diversity of this economically important group. Specimens from four entomological collections in Honduras were studied and an exhaustive search of all available literature was conducted. New information A total of 2,036 insects were examined. The fauna of Honduran coreids is now composed of 68 species. Nineteen species are recorded for the country for the first time and 17 species were found only in literature. Little is known about the biology and economic importance of most of the species. Keywords Taxonomy, diversity, agriculture, pest, Central America. © Linares C, Orozco J.

  • Biodiversity Changes in Vegetation and Insects Following the Creation of a Wildflower Strip
    Hochschule Rhein-Waal Rhine-Waal University of Applied Sciences Faculty of Communication and Environment Biodiversity changes in vegetation and insects following the creation of a wildflower strip A Case Study Bachelor Thesis by Johanna Marquardt Hochschule Rhein-Waal Rhine-Waal University of Applied Sciences Faculty of Communication and Environment Biodiversity changes in vegetation and insects following the creation of a wildflower strip A Case Study A Thesis Submitted in Partial Fulfillment of the Requirements of the Degree of Bachelor of Science In Environment and Energy by Johanna Marquardt Matriculation Number: 23048 Supervised by Prof. Dr. Daniela Lud Prof. Dr. Petra Blitgen-Heinecke Submission Date: 22.02.2021 Abstract With the Global Climate Change, the loss of biodiversity is one of the most current and biggest crises of today and the future. The loss i.e., the decrease of biodiversity, does not only have negative effects on vegetation and animals, but also on humans. If nature is doing well, people are doing well. In order to counteract the loss, this bachelor thesis attempts to increase plant and insect biodiversity at a specific location with insect-friendly seed mixtures and by measuring the change using comparison areas. Accordingly, the two research questions were addressed: (1) "How does plant-biodiversity change in the backyard and front yard on the seed mixture plot compared to plant-biodiversity in the backyard and front yard next to the seed mixture plot?" and (2) "How does insect-biodiversity change in the backyard and front yard on the seed mixture plot compared to insect-biodiversity in the backyard and front yard next to the seed mixture plot?" To answer these research questions and to obtain more suitable data, a wildflower strip was established in the backyard and one in the front yard, each with an adjacent reference field, to ensure equal environmental conditions and to detect changes in flora and fauna.

  • Conspecific and Heterospecific Cues Override Resource Quality to Influence Offspring Production
    Conspecific and Heterospecific Cues Override Resource Quality to Influence Offspring Production Christine W. Miller1*, Robert J. Fletcher Jr.2, Stephanie R. Gillespie1¤ 1 Department of Entomology and Nematology, University of Florida, Gainesville, Florida, United States of America, 2 Department of Wildlife Ecology and Conservation, University of Florida, Gainesville, Florida, United States of America Abstract Animals live in an uncertain world. To reduce uncertainty, animals use cues that can encode diverse information regarding habitat quality, including both non-social and social cues. While it is increasingly appreciated that the sources of potential information are vast, our understanding of how individuals integrate different types of cues to guide decision-making remains limited. We experimentally manipulated both resource quality (presence/absence of cactus fruit) and social cues (conspecific juveniles, heterospecific juveniles, no juveniles) for a cactus-feeding insect, Narnia femorata (Hemiptera: Coreidae), to ask how individuals responded to resource quality in the presence or absence of social cues. Cactus with fruit is a high-quality environment for juvenile development, and indeed we found that females laid 56% more eggs when cactus fruit was present versus when it was absent. However, when conspecific or heterospecific juveniles were present, the effects of resource quality on egg numbers vanished. Overall, N. femorata laid approximately twice as many eggs in the presence of heterospecifics than alone or in the presence of conspecifics. Our results suggest that the presence of both conspecific and heterospecific social cues can disrupt responses of individuals to environmental gradients in resource quality.
