Title: A Generalized Population Model based on Indian River Lagoon Dolphins.
Creator: Stonger, Jon, Noonburg, Erik G., Graduate College
Abstract/Description: For over a decade, researchers at Harbor Branch Oceanographic Institute have conducted surveys of the population of bottlenose dolphins, Tersiops truncatus, in Indian River Lagoon along the east coast of Florida. I have constructed a detailed 4-stage population model using the statistical program R. The model is used as a tool for conducting a viability analysis that projects the dolphin population into the future by analyzing the relationship between birth, calf survival and adult survival...
Show moreFor over a decade, researchers at Harbor Branch Oceanographic Institute have conducted surveys of the population of bottlenose dolphins, Tersiops truncatus, in Indian River Lagoon along the east coast of Florida. I have constructed a detailed 4-stage population model using the statistical program R. The model is used as a tool for conducting a viability analysis that projects the dolphin population into the future by analyzing the relationship between birth, calf survival and adult survival rates. The model also includes a power analysis, which compares survey frequency to expected confidence intervals in estimating abundance. The model shows a strong chance of viability over a 50 year time span, primarily due to the large population size of approximately 700 adult dolphins. The population is vulnerable to long periods of decline if birth, calf or adult survival rates fall below certain thresholds. The sensitivity analysis, based on the partial derivatives of the eigenvalue with respect to each matrix element, shows that the population is most sensitive to changes in adult survival, followed by birth rate and calf survival. Overall, the model simulates the future impacts of demographic change, and thereby provides a tool for conservation efforts.

Title: A Lime Softening System for Individual-Household Use Powered through Solar Energy.
Creator: Slater-Williams, Alexandria, Abtahi, Homayoon, Graduate College
Abstract/Description: In a study conducted by the World Health Organization WHO and United Nations Children’s Fund UNICEF, approximately 768 million people worldwide are not receiving sanitary drinking water suitable for consumption. The greatest levels of water contamination are within the less developed countries where individuals are unable to afford modern water treatment facilities. While there are many water treatment methods, lime softening proves to be one of the more effective approaches as it removes...
Show moreIn a study conducted by the World Health Organization WHO and United Nations Children’s Fund UNICEF, approximately 768 million people worldwide are not receiving sanitary drinking water suitable for consumption. The greatest levels of water contamination are within the less developed countries where individuals are unable to afford modern water treatment facilities. While there are many water treatment methods, lime softening proves to be one of the more effective approaches as it removes calcium, magnesium, arsenic, barium, beryllium, chromium, cooper, fluoride, lead, mercury, cadmium, nickel, uranium, radium, and radionuclides under the correct conditions. The US Environmental Protection Agency EPA has even defined lime softening as the best available technology BAT for removing uranium and radium. The issue with lime softening is that it is typically used for larger systems that serve whole communities. This project utilizes previous knowledge of lime softening to design a cost-efficient water clarification system with the ability to function on an individual-household basis while being powered by a solar unit. By condensing the system, we hope to make lime softening technology available for a wider spectrum of societies and expend the applications of lime softening.

Title: A Local Regression Approach to Computing the Cauchy Green Strain Tensor.
Creator: Kepley, Shane, Kalies, William D., Graduate College
Abstract/Description: The Cauchy Green strain tensor provides an effective tool for understanding unsteady flows. In particular, the dominant eigenvalue of this tensor has been seen to be a reliable estimator of the finite time Lyapunov exponent. We propose a new method for computing the CG strain tensor using a local quadratic regression LOESS technique. We compare this LOESS method with several classical methods using closed form flows, noisy flows, and simulated time series. In each case, the CG strain tensor...

In each case, the CG strain tensor produced by the LOESS method is remarkably accurate and robust compared to classical methods.

Title: A survey of Red Mangrove Rhizophora mangle prop root community diversity along a latitudinal gradient.
Creator: Aquino-Thomas, Jessene, Proffitt, C. Edward, Graduate College
Abstract/Description: Climate change is causing shifts in species geographic distributions. This trend is seen throughout the globe but the impact is especially noticeable in marine environments, which are highly sensitive to phenological and ecological alterations. Here, systemic shifts have cascading effects on the food web, productivity, and event timing. Throughout the tropics and the subtropics, mangrove trees act as the primary foundation species that dominate the intertidal zone. In particular, red...
Show moreClimate change is causing shifts in species geographic distributions. This trend is seen throughout the globe but the impact is especially noticeable in marine environments, which are highly sensitive to phenological and ecological alterations. Here, systemic shifts have cascading effects on the food web, productivity, and event timing. Throughout the tropics and the subtropics, mangrove trees act as the primary foundation species that dominate the intertidal zone. In particular, red mangroves Rhizophora mangle play a crucial role by acting as substrate for sessile species within their ecosystems. In these ecosystems, secondary foundation species that can colonize the prop roots of the red mangroves thereby further affecting the structure of the community. The original habitat architecture limits species variety and the effectiveness of species to utilize the space. Habitat architecture is strongly influenced by the foundation species that form the base for community structure. Investigating the connections between a primary foundation species, secondary foundation species, and the resulting biodiversity of sessile species is critical to understanding the variability of the ecosystem. Association with certain foundation species may provide a more positive environment for certain taxa than others and thus ease stressors that otherwise could functionally eliminate a species from the ecosystem. In addition, these associations can have cascading effects on neighboring species and neighboring ecosystems. Here, we conducted a presence/absence survey from Key West to the Kennedy Space Center to identify the species that utilized mangrove prop roots as habitat, their associations, and distributions.

Title: A Survival Analysis of Adolescent Friendships: The Downside of Dissimilarity.
Creator: Hartl, Amy C., Laursen, Brett, Cillessen, Antonius H. N., Graduate College
Abstract/Description: Friendships are important for adolescent adjustment and development; however, adolescent friendships are fleeting. Friend dissimilarity and undesirable individual attributes have been hypothesized to predict friendship dissolution. The present study tests each as predictors of adolescent friendship dissolution. A sample of 410 U.S. adolescents participated in a total of 573 reciprocated friendships originating in the 7th grade. These friendships were followed annually from 8th-12th grade to...
Show moreFriendships are important for adolescent adjustment and development; however, adolescent friendships are fleeting. Friend dissimilarity and undesirable individual attributes have been hypothesized to predict friendship dissolution. The present study tests each as predictors of adolescent friendship dissolution. A sample of 410 U.S. adolescents participated in a total of 573 reciprocated friendships originating in the 7th grade. These friendships were followed annually from 8th-12th grade to determine when each friendship dissolved. In the 7th grade, participants completed a peernomination inventory, and teachers completed a survey of each participant’s school competence. Discrete-time survival analyses used 7th grade friend dissimilarity and individual characteristics of sex, age, ethnicity, number of friends, peer acceptance, peer rejection, leadership, physical aggression, relational aggression, peer victimization, and school competence as predictors of the occurrence and timing of friendship dissolution. Friendships originating in the 7th grade were at greatest risk for dissolution during the first year. Only 1 percent of friendships that started in the 7th grade lasted 5 years. Friend dissimilarity on sex, peer acceptance, physical aggression, and school competence predicted friendship dissolution. At each grade, the odds of friendship dissolution were higher for friends dissimilar on these characteristics. Individual characteristics failed to predict friendship dissolution. The findings suggest compatibility is a function of similarity between friends rather than the presence or absence of a specific individual trait. Adolescents seeking friendships with individuals dissimilar from them on school-related characteristics risk suffering the downside of dissimilarity, namely rapid friendship dissolution.
