Show moreThis study contributed information for consideration as school districts determine grade span configuration as part of school design. The problem addressed was the extent to which student achievement may be impacted by the transition from one school to another from fifth to sixth grade in Florida public schools in order to provide data to school policy makers and school district administrators and add to the body of knowledge on the grade level configuration that contributed the most to student achievement in sixth grade. This was a causal-comparative study using quantitative data to analyze student scores at the school level for reading and mathematics on the 2014 Florida Comprehensive Achievement Test (FCAT) 2.0 assessment to explore the difference in achievement for sixth grade students with no school transition compared to those who had school transitions during middle school. A multivariate analysis of covariance (MANCOVA) was used to examine if a difference existed in the dependent variables of sixth-grade reading and mathematics achievement as measured by school mean developmental scale scores and the school percentage of students making learning gains on the FCAT 2.0 between schools with sixth grade as the transition year and without sixth grade as the transition year. The analyses were controlled for the covariates of the school percentages of socio-economic status as determined by free and reduced lunch rate, English Learner status, and exceptional student education status. Findings signified that schools with no school transition between fifth and sixth grade in Florida public schools had higher sixth-grade mean scores in reading and mathematics as measured by school mean developmental scale scores and in reading as measured by the percentage of school learning gains. This study offers insight into what grade configuration is more likely to positively impact student achievement during the middle grades and supports students remaining in an elementary setting with fewer transitions during the middle grades to most benefit reading and mathematics achievement. Findings are useful to school boards, superintendents, and school district administrators interested in educational policy development and research on transition especially when restructuring school grade configurations and building new school sites.

Title: A Comparison of Student Achievement in Florida Charter Schools with Not-For-Profit and For-Profit Management Models.
Creator: Kaprow, Maurice, Johnson, Jerry, Baldwin, Lee, Murray, Kenneth, McGee, Janet, University of Central Florida
Abstract / Description: In this study, the researcher compared student achievement in Florida charter schools by investigating differences in those managed by for profit and not-for-profit entities in all 530 charter schools that reported results on the 2016 Florida Standards Assessments in Grades 4, 8, and 10 in English Language Arts (ELA) and mathematics.

Show moreIn this study, the researcher compared student achievement in Florida charter schools by investigating differences in those managed by for profit and not-for-profit entities in all 530 charter schools that reported results on the 2016 Florida Standards Assessments in Grades 4, 8, and 10 in English Language Arts (ELA) and mathematics. Using a two-way analysis of covariance, this investigation found statistically significant achievement differences only in 10th-grade ELA when using poverty as a moderator variable and eighth-grade mathematics using both school cohort size and poverty as moderator variables. Also, the covariates of percentage of minority students, percentage of disabled students, and percentage of English language learners accounted for some of the variance in achievement results. These findings are similar to the extant literature where prior similar studies found mixed results between traditional public schools and charter schools and between not-for-profit and for-profit charter schools. Questions are raised by this research regarding the public funding of for-profit or proprietary charter schools if they do not routinely achieve superior results to traditional public schools. Implications for future research both building on this study and investigating other aspects of charter school performance include conducting similar studies on a recurring basis to better evaluate charter school performance, closer study on the role the covariates (minority status, disability status, and English language learner status) has on charter school student achievement, and a comparison of Florida's charter schools with Florida's traditional public schools.

Show moreWith the passage of the No Child Left Behind Act, schools and school districts have come under increased pressure to demonstrate student proficiency and success at the elementary, middle and high school levels. Each state is required to use standardized test data as evidence of student proficiency. The data is collected by each state and reported to the federal government to demonstrate progress. In Florida, the exam used to record proficiency is the Florida Comprehensive Assessment Test (FCAT). At all three levels, the FCAT is administered annually and the results are used to create school grades ranging from A-F. Florida high schools fall in the lowest 10% in the nation for graduation rates, graduating less than 60% of high school students. The pressure created by these high stakes tests have led to a growth in Florida secondary schools implementing the Advancement Via Individual Determination (AVID) program. AVID seeks to offer a rigorous curriculum with additional support to underserved students. However, some literature demonstrates that schools with AVID improve the success of not only AVID students, but the overall population as well. This is commonly referred to as the "AVIDization" of a school. This study used an independent t-test to compare middle schools in eleven Florida county school districts with AVID to non-AVID schools in the 2007-2008 school year in six main areas; a) FCAT Math scores, b) FCAT Reading scores, C) overall FCAT scores, d) frequency of disciplinary incidences, e) attendance rates, and f) overall FCAT scores with controlled data. In this study, 85 middle schools had AVID and 179 middle schools were non-AVID. In comparing AVID to non-AVID students in the six areas, the t-test demonstrated that schools with the AVID program did not outperform non-AVID schools in the three FCAT tested areas. Also, the data shows that AVID schools were more likely to have higher reported rates of disciplinary incidences then non-AVID schools.

Show moreThis digital thesis project examines the folk song collecting expeditions of the Federal Writers' Project (FWP) in Florida between 1935 and 1942. The FWP carried out numerous folk music collecting expeditions in Florida through the Works Progress Administration. Folklorists such as Zora Neale Hurston, Alan Lomax, and Stetson Kennedy led the expeditions and traveled throughout Florida to record blues, (")jook(") songs, work songs, and traditional music from African American, Cuban, Czech, Greek, Minorcan, Seminole, and Slavic communities. While romantic notions of nationalism in the 1930s often promoted homogenization, the FWP emphasized inclusiveness and highlighted cultural diversity. The FWP's approach challenged popular concepts concerning the homogeneousness of American culture and identity. Their recordings indicate that Florida was a patchwork of varied cultures. Yet, Florida's diversity is not adequately highlighted in popular history. Historians often see Florida history through the eyes of the mythologized (")Florida Cracker("), the Celtic pioneer who settled in Florida in the eighteenth century, but the Cracker perspective represents but a square in the patchwork quilt that makes up Florida's cultural history. An exploration of the FWP folk song recordings brings Florida's diversity to the forefront and increases the public's understanding of the state's cultural variety. The project includes a podcast series that features stories about the FWP expeditions, the folklorists, the performers, and the music. It also includes an interactive exhibit that is currently a work in progress. Source materials derived from open-access public archives create an immersive, interactive learning experience.

Show moreThis thesis is an examination of the unique conditions for African-descended slaves in St. Augustine, Florida, during the First Spanish Period. St. Augustine was an important garrison at a remote point in the Spanish Empire at the edge of a hostile frontier. As such, economics were less a priority than defense. Slaves, therefore, received different treatment here than in English colonies or even other Spanish colonies. Due to the threat of Protestantism, religious adherence was more important as a test of loyalty than ethnicity and slaves and freed-people were able to integrate better than in other Spanish holdings. In order to explore this integration, the meticulous records of the St. Augustine clergy are used. Infant baptism rates are used to show the influence of Spanish culture as well as at least a semblance of adherence on the part of African-descended people. The baptism of adults, meanwhile, and the role of the godparent are examined to show integration and the complex nature of this unique religious phenomenon.

Show moreThe purpose of this study was to identify the perceptions that central Florida public high school principals had regarding the Florida School Indicators Report (FSIR) and its usefulness. The FSIR, published by the Florida Department of Education, was designed to be a comprehensive, single source document for parents, lawmakers, and school administrators to compare key performance indicators to similar schools or districts state wide. It provided information on 74 different indicators of school or district performance. A total of 70 public high school principals from 13 central Florida school districts responded to a postal survey and provided their perceptions regarding the importance of indicators in the FSIR, how they used the FSIR at their schools, and what barriers they felt affected the ability of their administrative staffs to collect and analyze data on the FSIR indicators. Eighteen of the 70 principals participated in follow-up telephone interviews. Quantitative and qualitative analysis of the postal surveys and interviews revealed the principals perceived FSIR indicators related to Florida's mandated Florida Comprehensive Assessment Test (FCAT) as the most important indictors in the FSIR. The indicators FCAT Results and FCAT Writes were ranked first and second respectively in priority by the participating principals. This finding demonstrated the importance that principals placed on the state's high-stakes test. Other categories of FSIR indicators are were also ranked in the findings reported in this study, along with how the principals used the FSIR at their schools. The data collected from the postal survey revealed there was a statistically significant relationship between the priority principals assigned to the FSIR indicators and their ability to collect and analyze data related to them. In addition, survey data allowed development of multiple regression models that could be used to predict the priority principals assigned to several FSIR categories of indicators based on the ability to collect and analyze data. The study findings indicated that principals perceived lack of time for data analysis as the biggest barrier they faced when evaluating the FSIR indicators. After the lack of time, principals rated lack of administrator training in data analysis as the second biggest obstacle to using the FSIR. The findings indicated that principals felt the availability of data and technology were not significant barriers to their staff's ability to conduct data analysis on the FSIR. The conclusions drawn from the study were that central Florida high school principals perceived the results on the state's mandated Florida Comprehensive Assessment Test (FCAT) to be the most important indicators in the FSIR. In addition, the research identified that the lack of time was the single greatest barrier principals encountered when it came to collecting and analyzing data on the FSIR. A lack of training programs in data collection and analysis for administrators was also noted in the findings.

Show moreThis thesis project incorporates podcasts and high resolution digital imagery visualizations into a single online exhibit to democratize archival material on the web. It employs contemporary new museology and digital history methodological frameworks, and utilizes the burgeoning medium of podcasting to increase public understanding and interaction with an historical period. For this project I have partnered with the Florida Historical Society and have utilized original materials from their collection relating to the colonial fur trade in Florida. The study of the North American fur trade has recently expanded to include more information about the indigenous societies engaged in the trade through closer examination of primary source documents, and this digital exhibit, hosted by the Florida Historical Society, created a series of module entities to achieve that end. The exhibit consists of three sections, each exploring a different aspect of the traditional discourse surrounding the colonial American fur trade in Florida, including the voices of indigenous populations and their agency in trade negotiations. Each podcast has aired as part of the Florida Historical Society's weekly radio magazine, Florida Frontiers, which is broadcast throughout the state, and is archived on the Society's website. The exhibit enhances the scholarly discussion on public history and digital history, while utilizing new media such as podcasts and interactive digital maps to create a more immersive user experience with primary source material to answer questions concerning the colonial fur trade in Florida. The project has combined new mediums of historical interpretation with traditional museum methodology and historical analysis to create a multi-faceted, unique digital experience on the web.

Show moreEvaluating relative species competitive strength is a central question in community ecology, with strong implications for invasion ecology. Models assessing invader success consider three components: distribution, abundance and per-capita impact. However, relative strength and interactions among these factors remain unclear when applying to specific invasion scenarios. We hypothesized that performance of native and non-native species will vary as a function of direct and indirect effects at different abundances and scales. We conducted a replacement experiment between two dominant grasses in subtropical grasslands (the native Axonopus fissifolius and the non-native Paspalum notatum) in central Florida, USA. Thirty fenced plots (1 m x 3 m each) representing a gradient (15 levels) of increasing non-native groundcover and decreasing native groundcover were set up in November 2017. We transplanted individuals of these two species in subplots (12 subplots and 36 transplants per plot; 1080 plants in total) in a 2*2 factorial design (mixed /single focal species * 2/4 transplants per subplot). Leaf length/number and plant biomass were evaluated at the beginning and end of the experiment along with plot species composition and soil nutrients. Over 92% of transplants of each grass species survived until harvest (11 months). There were significant differences in leaf length, leaf number and plant biomass between conspecific/allospecific subplots. Both P. notatum and A. fissifolius performed better when transplanted in non-native P. notatum subplots. There were also interactions between conspecific/allospecific subplot treatment (direct effects) and the gradient of increasing Paspalum notatum /decreasing Axonopus fissifolius groundcover (indirect effects) treatments. Increasing P. notatum in the whole plot made environments more favorable for both grass species. Effects were consistent for leaf length/number and biomass of the two focal species. More comprehensive evaluation on indirect effects need to be considered when examining competition between non-native species and native species.

Show moreDomestic violence (DV) is a global issue that can affect anyone regardless of what role they play in a family household. It does not discriminate by education, age, religion, etc. DV includes any type of violence or abuse that occurs within a domestic setting. For the purposes of this study, this content primarily focuses on intimate partner violence (IPV) as the main form of DV and is used interchangeably throughout the text. This study examines the influence of population density on arrest rates for DV and some factors behind the likelihood of arrests in urban and rural areas. The literature between both of these societies has demonstrated a clear difference in social behaviors that shape the response to DV (Websdale and Johnson 1998). Normative social influence theory suggests that people's influence may lead someone to conform in order to be liked or accepted by a group (Izuma 2017). This theory hypothesizes that the proportion of people living in rural per county will have fewer arrests for DV than the proportion of people living in non-rural areas because of the need for positive relationships that can lead to conformity (Izuma 2017). Furthermore, it is predicted that there are less arrests in rural areas because of the effects of informal social controls in these areas. Informal social controls can take place between police and citizens that may interact more personally through socialization. An example is when citizens take matters into their own hands, therefore prolonging the reporting of crimes to police. This study uses secondary data provided by sources such as the Florida Department of Law Enforcement (FDLE) website and Social Explorer. Broader implications of this research are that it could shed some light on the social dynamics that impact the outcome of crime in both densely populated and sparsely populated areas.

Show moreSea level rise (SLR) is posing a great risk of flooding and inundation to coastal areas in Florida. Some coastal nesting species, including sea turtle species, have experienced diminished habitat from SLR. In an effort to assess the economic and ecosystem service loss to coastal areas with respect to sea turtles Contingent Valuation Method (CVM) and Habitat Equivalency Analysis (HEA) were used. The CVM was used to measure the economic impacts of SLR on sea turtles. Open-ended and dichotomous choice CVM was used to obtain the willingness to pay (WTP) values of Florida residents to implement certain mitigation strategies which would protect Florida's east coast sea turtle nesting areas. The problem of sample selection bias was reduced by surveying residents of two cities that would potentially have varying interest in coastal conservation due to their relative distance from the coast. The hypothetical WTP of Florida households to implement policies designed to protect sea turtle habitat from development encroachment was estimated to be between $21 and $29 per year for a maximum of five years. Characteristics of respondents were found to have statistically significant impacts on their WTP. Findings include a negative correlation between the age of a respondent and the probability of an individual willing to pay the hypothetical WTP amount. Counter intuitively, it was found that WTP of an individual was not dependent on prior knowledge of the effects of SLR on sea turtle habitat. As the level of this awareness increased, the probability to pay the hypothetical WTP value decreased. The greatest indicators of whether or not an individual was willing to pay to protect sea turtle habitat were the respondents' perception regarding the importance of sea turtle population health to the ecosystem, and their confidence in the conservation methods used. Concepts of Habitat Equivalency Analysis were used in order to determine the ecosystem service lost due to SLR. The study area of Archie Carr National Wildlife Refuge (ACNWR) has a continually increasing sea turtle population due to various conservation efforts. However, how the inundation of the coastal area will injure this habitat was assessed, and if mitigation strategies to compensate for the loss are necessary. The carrying capacity (CC) of the refuge was chosen as the metric of the ecosystem service. Using the estimated area of ACNWR and the approximate area needed by a sea turtle to nest, the theoretical number of sea turtle nests possible on the refuge was calculated. This value was then projected to the year 2100 using the sea level rise scenarios provided by IPCC (2007) and NRC (2010). In order to quantify the injury caused by the decrease in the refuge's CC, the number of sea turtle nests on the refuge was projected to the year 2100 using the data obtained over the past 30 years. The analysis concludes a potential loss of service to be experienced as early as 2060's due to the carrying capacity of the refuge diminishing with the loss of the habitat due to the increase in the mean sea level.

Show moreNorth American grassland birds show long-term population declines that generally exceed the declines of other bird groups. Efforts to conserve grassland birds require knowledge of diet and habitat requirements during both the breeding and nonbreeding periods of annual life cycles. This dissertation investigated sparrow habitat associations within two defined plant communities of the dry prairie ecosystem, the dry-mesic and wet-mesic prairie, for four prescribed fire treatments over two consecutive winters. Grasshopper and Henslow's sparrows showed higher relative abundance in wet-mesic prairie and Bachman's Sparrows were more abundant in dry-mesic prairie across all fire treatments. Abundances of Grasshopper and Bachman's sparrows were best predicted by plant community association and secondly by time since fire; whereas for Henslow's Sparrows, habitat and time since fire were equally important. Fall molt-period diets and diet overlap were modeled for resident Florida Grasshopper and Bachman's sparrows using stable carbon and nitrogen isotope ratios of bird feathers and potential food sources, e.g., arthropods and seeds. Grasshoppers (Orthoptera, including a variety of species foraging on both C3 and C4 herbs), spiders, dragonflies, flies, beetles and weevils comprised the majority of the diets of adult and juvenile Florida Grasshopper Sparrows and Bachman's Sparrows, but in differing proportions. Despite the similarity in reconstructed diets for the two sparrow species, analysis of diet overlap suggested that approximately half of the Florida Grasshopper Sparrows had diets consisting of higher trophic level prey than Bachman's Sparrows. Winter diets and diet overlap among Grasshopper, Henslow's, and Bachman's sparrows were reconstructed using stable carbon and nitrogen isotope ratios of feathers and potential arthropod and seed food sources. Sparrows were captured and recaptured in winter 2007-2008 using systematic flush-netting, removing a tail feather at first capture and then removing the regrown feather when birds were recaptured. Winter diets of all three sparrows included a variety of arthropods, grass seeds, and sedge seeds, but Bachman's Sparrow winter diets spanned greater trophic diversity than either of the migratory sparrows. Estimated diets of Henslow's and Grasshopper sparrows differed from that of Bachman's Sparrow but Henslow's Sparrow diets did not differ from Grasshopper Sparrow diets. This is the first study of fall and winter sparrow diets in Florida based on stable isotopes and the first study in peninsular Florida on habitat associations of ground-dwelling sparrows.

Show moreWet detention ponds are used for stormwater treatment across the United States and reduce most pollutants by at least 60%, but only remove 30% of total nitrogen. Floating Treatment Wetlands (FTWs) are an emerging technology that uses aquatic plants suspended in the pelagic zone to remove nitrogen through vegetative assimilation and microbial denitrification. A before-after field experiment evaluated nitrogen removal in a an existing pond in Orlando, FL, retrofitted with BioHaven(&)#174; FTWs planted with the aquatic macrophytes Juncus effusus (Soft Rush) and Pontederia cordata (Pickerelweed). Surface water samples were used to compare the nitrogen-removal performance of the pond under both storm and non-storm conditions during a pre-analysis phase (control) to post-analysis after FTW deployment. The evaluation revealed similar TN removals in non-storm conditions during pre-analysis and post-analysis periods (-1% and -3%, respectively). During storm conditions, there was a negative TN removal of -26% in the pre-analysis compared to the positive 29% removal post-analysis. In addition, nitrogen concentrations for organic-nitrogen, ammonia/ammonium, and nitrites/nitrates were used as input for calibrating and validating a system dynamics model to predict multiple, interacting nitrogen species' transformation and translocation across the abiotic and biotic components of water, sediment, plants, and atmosphere. The validated model created in STELLA v.9.4.1 was used to simulate alternative designs to achieve maximum nitrogen removal based on the treatment efficiency in the evaluation. Simulations predicted 60% FTW coverage at the experimental planting density (22 per square meter) could achieve maximum nitrogen removal. Alternatively, similar nitrogen removal could be achieved at only 15% FTW coverage by increasing plant density. The model can be used as a low-cost tool for designing FTW technology applications and monitoring nitrogen transport.

Show moreThe purpose of this study was to determine if first year teachers in Florida perceived they were adequately prepared by their preservice education programs to meet the National Educational Technology Standards for Teachers (NETS-T). The study was designed to gather data about first year teacher perceptions of personal technology proficiency and self-reported technology integration practices. The data were measured using the First Year Teacher Perceptions Related to Preparedness to Meet National Educational Technology Standards for Teachers (NETS-T) survey instrument. The sample (N=257) for this study was drawn from the population of Florida first year PreK-12 public classroom teachers from the 2005–2006 school year who were still teaching during the 2006-2007 school year. Demographic variables, perceptions of personal technology skills, and self-reported technology integration practices were collected on the sample. Descriptive and comparative statistics were used to identify relationships between the variables. It was concluded that first year teachers in Florida who held a professional teaching certificate or graduated from a Florida public university's teacher education program perceived they were better prepared to meet national educational technology standards than first year teachers in Florida who did not. It was also determined that there was a statistically significant relationship between first year teacher perceptions for preparedness for technology integration and their perceived personal technology skills, as well as between self-reported technology integration practices of first year teachers and their perceptions of their ability to integrate technology. Two additional findings came to light during the study. The majority of first year teachers in Florida did not take the traditional university teacher preparation program as their path to certification. Additionally, the vast majority of first year teachers in Florida gave credit to independent learning in increasing their own personal technology skills.

Title: Flying under the LiDAR: relating forest structure to bat community diversity.
Creator: Butterfield, Anna, Weishampel, John, Noss, Reed, King, Joshua, University of Central Florida
Abstract / Description: Bats are important to many ecological processes such as pollination, insect (and by proxy, disease) control, and seed dispersal and can be used to monitor ecosystem health. However, they are facing unprecedented extinction risks from habitat degradation as well as pressures from pathogens (e.g., white-nose syndrome) and wind turbines.

Show moreBats are important to many ecological processes such as pollination, insect (and by proxy, disease) control, and seed dispersal and can be used to monitor ecosystem health. However, they are facing unprecedented extinction risks from habitat degradation as well as pressures from pathogens (e.g., white-nose syndrome) and wind turbines. LiDAR allows ecologists to measure structural variables of forested landscapes with increased precision and accuracy at broader spatial scales than previously possible. This study used airborne LiDAR to classify forest habitat/canopy structure at the Ordway-Swisher Biological Station (OSBS) in north central Florida. LiDAR data were acquired by the National Ecological Observatory Network (NEON) airborne observation platform in summer 2014. OSBS consists of open-canopy pine savannas, closed-canopy hardwood hammocks, and seasonally inundated basin marshes. Multiple forest structural parameters (e.g., mean, maximum, and standard deviation of canopy height) were derived from LiDAR point clouds using the USDA software program FUSION. K-means clustering was used to segregate each 5x5 m raster across the ~3765 ha OSBS area into six different clusters based on the derived canopy metrics. Cluster averages for maximum, mean, and standard deviation of return heights ranged from 0 to 19.4 m, 0 to 15.3 m, and 0 to 3.0 m, respectively. To determine the relationships among these landscape-canopy features and bat species diversity and abundances, AnaBat II bat detectors were deployed from May to September in 2015 stratified by these distinct clusters. A statistical regression model selection approach was performed in order to evaluate how forest structural attributes such as understory clutter, vertical canopy structure, open and closed canopy, etc. and landscape metrics influence bat communities. The most informative models showed that a combination of site-specific (e.g., midstory clutter and entropy) and landscape level attributes (e.g., area of water and service road length) contributed to bat community patterns. This knowledge provides a deeper understanding of habitat-species interactions to better manage survival of these species and provides insight into new tools for landscape management as they apply to specific species.

Show moreA major hurdle in freight demand modeling has always been the lack of adequate data on freight movements for different industry sectors for planning applications. Freight Analysis Framework (FAF), and Transearch (TS) databases contain annualized commodity flow data. The primary motivation for our study is the development of a fused database from FAF and TS to realize transportation network flows at a fine spatial resolution (county-level) while accommodating for production and consumption behavioral trends (provided by TS). Towards this end, we formulate and estimate a joint econometric model framework grounded in maximum likelihood approach to estimate county-level commodity flows. The algorithm is implemented for the commodity flow information from 2012 FAF and 2011 TS databases to generate transportation network flows for 67 counties in Florida. The data fusion process considers several exogenous variables including origin-destination indicator variables, socio-demographic and socio-economic indicators, and transportation infrastructure indicators. Subsequently, the algorithm is implemented to develop freight flows for the Florida region considering inflows and outflows across the US and neighboring countries. The base year models developed are employed to predict future year data for years 2015 through 2040 in 5-year increments at the same spatial level. Furthermore, we disaggregate the county level flows obtained from algorithm to a finer resolution - statewide transportation analysis zone (SWTAZ) defined by the FDOT. The disaggregation process allocates truck-based commodity flows from a 79-zone system to an 8835-zone system. A two-stage factor multiplication method is proposed to disaggregate the county flow to SWTAZ flow. The factors are estimated both at the origin and destination level using a random utility factional split model approach. Eventually, we conducted a sensitivity analysis of the parameterization by evaluating the model structure for different numbers of intermediate stops in a route and/or the number of available routes for the origin-destinations.

Show moreCrayfish are an economically and ecologically important invertebrate, however, research on crayfish in native habitats is patchy at best, including in Florida, even though the Southeastern U.S. is one of the most speciose areas globally. This study investigated patterns of abundance and habitat distribution of two crayfishes (Procambarus paeninsulanus and P. fallax) in two Florida spring-fed rivers (Wakulla River and Silver River, respectively). Study sites were surveyed once each season from April 2015 to March 2016 with baited minnow traps checked every other day, four times each survey. Habitat and environmental parameters evaluated included dominant vegetation or bottom type, percent cover, organic matter content, water depth, moon illumination and dissolved oxygen. Abundance was estimated with N-mixture models. Model selection judged the relative evidence between hypotheses relating habitat and environmental covariates to crayfish abundance. P. paeninsulanus distribution and abundance in Wakulla River was explained by time of year, dissolved oxygen and dominant bottom and vegetation type. P. fallax distribution and abundance in Silver River was explained by time of year and percent coverage of vegetation. Detection of P. paeninsulanus was higher than P. fallax and abundance of P. paeninsulanus was more heterogenous than P. fallax (6-18 versus 12-14 per site in summer survey). Distribution of P. paeninsulanus as described by vegetation and bottom type also seems to follow heterogeneity in management areas in Wakulla River. Results will assist managers in understanding potential impact of herbicidal control of Hydrilla verticillata on crayfish. This study also fills knowledge gaps on Florida crayfish natural history and ecology.

Show moreLegends of the Fabricated Wild is a feature-length body of work of landscape films. Voice-Destroy, Self-Portrait: Impermanence and the titular Legends of the Fabricated Wild are the experimental films that comprise my body of work. Keep your Distance, a single-channel installation, is a supplemental piece.Legends of the Fabricated Wild frames the complex interaction between a filmmaker and the collective unconsciousness of the natural environment, a theory outlined by Carl Jung, considering the implications and discoveries along the way. Subtle movement and precise compositions provide a transcendental perspective on the natural Florida landscape. Images of landscapes devoid of human figures are structured together in my work to meditate on the environment and the way humanity has shaped the landscape. Super 8mm and 16mm analog film frames expansive landscapes in a square image and challenges modern cinematic representations by applying the texture of celluloid. High definition digital video contrasts analog film. I foreground artificiality and the ways humanity has utilized the landscape through this medium.While searching for places to document (")pure(") or untouched landscapes, I discovered that modern landscapes are always influenced by the exchange between humanity and the natural environment. I wanted to foreground my own interaction with the natural Florida environment and challenge my interests and dominant ways of viewing landscapes. Through the assembly of a cinematic essay of landscape images with subtle motion, I foster an appreciation for the natural environment in an age of hyper-activity and exploitation of the landscape.

Show moreLonely Monsters is a full-length feature screenplay that explores the ways in which a classic damsel narrative may be reconsidered. It offers ideas on how death and girlhood may find symmetry. The characters within Lonely Monsters deal with loss, identity of the self versus the world's ideas on self-identity, place, gender, and class. Utilizing the elements of a fairy tale, the narrative seeks to complicate the roles of gender in a cautionary tale. Set in the fictional Florida town of Puerto Palmera, an economic divide between the Estates and the Glades makes for a ripe, troublesome environment for a foul modern-day aristocrat who masquerades as a grandiose and romantic prince. The story's protagonist, Fisher Franklin, loses two key relationships(-)as well as her sound mind(-)in the wake of the false prince's folly. Utilizing her experiences as a child within the lavish lives of the Estates(-)at the desire of a wealthy and secretive benefactor with motives of her own(-)Fisher creates a persona who becomes entangled in a lustful and dangerous liaison with Wyatt Sharpe, the villainous playboy. By assuming this persona, Fisher recasts herself as the damsel, the monster, and the heroine.
