Wading Bird Prey Production And Prey Selection In A Dynamic Wetland, Jessica A. Klassen

Electronic Theses and Dissertations 2010 - 2019

Anthropogenic impacts, such as habitat destruction and spread of exotic species, are contributing to the sixth major extinction event in Earth’s history. To develop effective management and conservation plans, it is important to understand the ecological drivers of at-risk populations, assess the ability of a population to adapt to environmental change, and develop research methods for long-term ecosystem monitoring. I used wading birds nesting in the Florida Everglades, USA as a model system to address the challenges of managing and monitoring populations within an ecosystem greatly impacted by anthropogenic activities. Specifically, my project investigated 1) the prey selection of wading …

Verb Memory And Text Comprehension, Lamiya Khan

Electronic Theses and Dissertations 2010 - 2019

Kersten, Earles, and Berger (2015) reported a distinction between two kinds of motion representations. Extrinsic motions involve the path of a person or object, with respect to an external frame of reference. Intrinsic motions involve the manner in which the various parts of a person or object move. They found that intrinsic motions are encoded and remembered with the corresponding actor performing the motions in a unitized memory representation. Extrinsic motions are encoded as separate memory representations, making them more difficult to accurately associate with the correct actor. In the proposed experiment, I will examine the generality of this distinction …

Wading Bird Reproductive And Physiological Responses To Environmental Disturbance In A Managed Lake Ecosystem, Jennifer E. Chastant

Electronic Theses and Dissertations 2010 - 2019

Wetlands are some of the most diverse and productive ecosystems on earth. Water-level fluctuations determine the ecological function of shallow lakes and wetlands. Currently, anthropogenic modification to water-level fluctuations is the leading source of ecological degradation in lake and wetland ecosystems worldwide. I used wading birds nesting in Lake Okeechobee, as a model system to address the challenges of environmental restoration within an ecosystem greatly impacted by anthropogenic activities. Specifically, I 1) identified environmental factors most important for predicting the number of wading bird nests, 2) tested the assumptions of both the match-mismatch and the threshold hypothesis by modeling the …

Women’S Plasticity During Childhood And Their Influence On Rape-Avoidance Behaviors, Sammy Penaloza

Electronic Theses and Dissertations 2010 - 2019

Evolutionary theory predicts that sexual coercion and rape are likely to occur in any species in which males are more aggressive, more eager to mate, more sexually assertive, and less discriminating in choosing a mate (Thornhill & Palmer, 2000). McKibbin and Shackelford (2011) state that males of many species have evolved strategies to sexually coerce and rape females. It is for this reason that researchers have speculated that several female traits or behaviors evolved to reduce the risks of being raped (McKibbin & Shackelford, 2011). The rationale behind the proposed experiment examined whether parents’ childrearing practices and women’s plasticity during …

Creating A Religious Divide: Journeys Through Hell In British And American Science Fiction, Advitiya Sachdev

Electronic Theses and Dissertations 2010 - 2019

Science fiction, like any other genre, is sub-divided into categories. Yet scholars in the field have long debated the existence of multiple, regional sf genres. The most critiqued of these classifications is between sf produced in Britain, and America. Though Britain remains the birthplace of sf, American author have undoubtedly left a mark on the genre. Scholars mark this difference in the writing styles and themes of authors in these regions. To examine this difference, I analyze two authors that have worked on a common theme: religion and in particular, the concept of hell. Evaluating the arguments put forth by …

Complexity And Blocked Trial Presentation In A Novel Verb Generalization Task, Rita Pruzansky

Electronic Theses and Dissertations 2010 - 2019

The current study examined the role of complexity and initial variability of exemplars during learning in verb generalization. Children and adults learned two novel verbs in the context of two novel creatures across two sessions. After a second training session, participants completed a generalization task during which they were required to identify the verbs when presented with seven novel creatures of varying levels of complexity. Performance was compared across age group and condition. Participants who initially learned the verbs in the context of a single, simple exemplar demonstrated a higher proportion of correct responses than participants who initially learned the …

Design And Deployment Analysis Of Morphing Ocean Structure, Yanjun Li

Electronic Theses and Dissertations 2010 - 2019

As humans explore greater depths of Earth’s oceans, there is a growing need for the installation of subsea structures. 71% of the earth’s surface is ocean but there are limitations inherent in current detection instruments for marine applications leading to the need for the development of underwater platforms that allow research of deeper subsea areas. Several underwater platforms including Autonomous Underwater Vehicles (AUVs), Remote Operated Vehicles (ROVs), and wave gliders enable more efficient deployment of marine structures. Deployable structures are able to be compacted and transported via AUV to their destination then morph into their final form upon arrival. They …

Determining The Effects Of Fire On Ridge Shape Complexity In The Central Everglades, Jacob Dombrowski

Electronic Theses and Dissertations 2010 - 2019

Self-organized spatial patterning of microtopographic features is a trademark characteristic of the Everglades landscape. Anthropogenic modifications to Everglades’ hydrology have reduced and degraded pattern, where ridges occur at higher elevations and spread into open water sloughs under dryer conditions. Wildfire is an important ecological force in the central Everglades and may maintain ridge-slough patterning through reducing ridge size and complexity, and thus preserve habitat heterogeneity. To investigate fire as a patterning mechanism in the central Everglades I examined the shape complexity and area distribution of ridges along a chronosequence of time since fire. Shape complexity did not change following fire, …

Discovery Of Loxosomella Vivipara (Entoprocta: Loxosomatidae) In The Marine Sponge Hippospongia Cf. Gossypina (Porifera: Spongiidae) In The Florida Keys, Rachel Plunkett

Electronic Theses and Dissertations 2010 - 2019

Populations of a marine invertebrate symbiont were found on the outer surface and internal spaces of a keratose sponge from a shallow bay in the Florida Keys in May 2014. A total of 24 specimens of the seagrass and reef-dwelling sponge were collected between May 2014 and August 2015 to provide material to identify both host and symbiont, and elucidate information on the nature of the association. Based on a morphological analysis via light microscopy, histology, and scanning electron microscopy (SEM), and 99% similarity in aligned partial sequences from 28S and 18S nuclear ribosomal genes (rDNA), the symbiont was identified …

Determinants Of Aid Effectiveness In Agriculture: Non-Governmental Organizations (Ngos) In Haiti, Jean M. Pierre

Electronic Theses and Dissertations 2010 - 2019

For years, scholars have investigated the effectiveness of aid dollars. Some scholars measure aid effectiveness at the country level in terms of achieving good governance, promoting democratic accountability, accomplishing growth goals, or attaining macroeconomic goals. This study looks at the aid flowing through nongovernmental organizations (NGOs). It posits that effective aid consists of resources and processes that promote sustainability. It attempts to uncover the meaning of sustainability for the NGOs and recipients that are involved in agriculture while surveying how the aid process works. It looks at NGOs and recipients, resource flow, and activities, and sought to understand the elements …

Distribution And Diversity Of Benthic Foraminifera Within The Nearshore Ridge Complex Off Pompano Beach, Broward County, Florida., Caitlin Hanley

Electronic Theses and Dissertations 2010 - 2019

Benthic foraminifera are exceptional organisms with distinctive features that allow for interpretation of both past and present environmental conditions. Some benthic foraminifera are widely distributed while some are restricted to specific environments due to their way of life. Foraminiferal assemblages south of Biscayne Bay and north of Cape Canaveral have previously been investigated; however, a gap exists in data covering a transitional zone along the Florida coast between the tropical waters of the western Atlantic and the cooler coastal waters along the North American coast. The purpose of this study was to collect baseline data on the benthic foraminifera of …

Diamonds And Ash: Class And Social Mobility In Seventeenth Century Cinderella, De Arce Laura Diaz

Electronic Theses and Dissertations 2010 - 2019

This thesis discusses the intersections of class and the lack of social mobility in three versions of Cinderella from the seventeenth century. The works covered are are Giambattista Basile's "La Gatta Cennerentola" ["The Cat Cinderella"] (c.1634), Charles Perrault's "La Petite Pantoufle de Verre" ["The Glass Slipper"] (1697), and Marie- Catherine D'Aulnoy's "Finette Cendrone" ["Clever Cinderella"] (1697). The seventeenth-century versions of Cinderella all reaffirm the existing class system. In each of these versions the message is that the ruling elite must maintain or regain to their status. We can see this by the ways in which the characters gain and lose …

Effect Of Deepwater Horizon Crude Oil On Olfaction And Electroreception In The Atlantic Stingray, Dasyatis Sabina, Eloise Cave

Electronic Theses and Dissertations 2010 - 2019

Crude oil causes both lethal and sublethal effects on marine organisms, but the impact upon sensory function remains unexplored. Elasmobranchs rely upon the effective functioning of their sensory systems for use in feeding, mating, and predator avoidance. The objective of this study was to test the effect of crude oil upon the olfactory and electroreceptive sensitivity of the Atlantic stingray, Dasyatis sabina. The magnitudes of the electro-olfactogram (EOG) responses were significantly depressed by 26% (Glutamic Acid) to 157% (Cysteine) for all amino acids when stingrays were exposed to crude oil. The shapes of the EOG responses when exposed to oil …

Tracking A Deadly Virus Highly Pathogenic Avian Influenza In Wild Birds, Tom Deliberto, Gail Keirn

United States Department of Agriculture Wildlife Services: Staff Publications

For Dennis Kohler, the call was somewhat unexpected. On a cold, windy morning in December 2014, Kohler sat in his Colorado office reviewing research plans for upcoming disease studies. A few hours later, Koehler's colleagues at the National Wildlife Health Center in Madison, Wis., called to notify him and other members of the U.S. Department of Agriculture's National Wildlife Disease Program (NWDP) that recent samples collected from wild birds in Washington State had tested positive for highly pathogenic avian influenza (HPAI).

Earlier that month, a die-off of mallards (Anas platyrhynchos), American wigeon (A. Americana) and northern …

Characterization Of A Phosphonate-Specific Cytidylyltransferase, Kissa Batul

Theses and Dissertations (Comprehensive)

Antibiotic resistance is a major global health concern that requires new therapeutic approaches. Furthermore, a lack of narrow spectrum antibiotics on the market produces unintended consequences with respect to changes in our microbial make up. Phosphonates are reduced versions of phosphates that possess a C-P bond which is more resistant to enzymatic and chemical degradation. The role of phosphonate containing macromolecules (e.g. cell surface polysaccharides) remains enigmatic, however their presence suggests that they may confer an advantage. The biosynthesis of phosphonate-containing macromolecules is unknown, but a pathway is proposed involving aLicC type cytidylyltransferase-catalyzed conjugation to a phosphonate followed by a …

Children’S Ability To Identify An Unusual Occurrence Of A Repeated Event, Mckenzie K. Vanderloon

Theses and Dissertations (Comprehensive)

Abstract

Research on script memory shows that individuals have a difficult time isolating single instances of a repeated event because a generic script (e.g., one has a generic script for typical grocery shopping; grab a cart, gather items, then pay) has formed over time. Scripts capture the “gist” of what usually happens and allow individuals to predict what probably occurred based on the robustness of the script. Thus, individuals are able to identify details of what occurs; however, piecing which details came from a particular incident poses its challenges, especially for children. Source monitoring is the ability to accurately differentiate …

Characterization Of The Protective Role Of Regulatory T Cells In Experimental Periapical Lesions Development And Its Chemoattraction Manipulation As A Therapeutic Tool, Carolina Favaro Francisconi, Andreia Espindola Vieira, Cláudia Cristina Biguetti, Andrew J. Glowacki, Ana Paula Favaro Trombone, Ariadne Letra, Renato Menezes Silva, Charles S. Sfeir, Steven R. Little, Gustavo P. Garlet

School of Podiatric Medicine Publications

Introduction

The pathogenesis of periapical lesions is determined by the balance between host pro-inflammatory immune response and counteracting anti-inflammatory and reparative responses, which include regulatory T cells (Tregs) as potential immunoregulatory agents. In this study, we investigated (in a cause-and-effect manner) the involvement of CCL22-CCR4 axis in Tregs migration to the periapical area and the role of Tregs in the determination of outcomes in periapical lesions.

Methods

Periapical lesions were induced in C57Bl/6 (WT) and CCR4KO mice (pulp exposure and bacterial inoculation), and treated with anti-GITR to inhibit Tregs function or alternatively with CCL22-releasing, PLGA particles to induce site-specific migration …

Differentiating Deference, Anya Bernstein

Journal Articles

When an administrative agency’s interpretation of an ambiguous statutory term is challenged in court, the Chevron doctrine instructs judges to evaluate whether it is reasonable. But how does a court know reasonableness when it sees it? Here, I first show that reasonableness review is more complex than it might seem. Contrary to common images, for instance, courts do not determine a range of reasonable interpretations; and that is a good thing, because they are not competent to do so. Moreover, because traditional statutory interpretation approaches presume the existence of one correct meaning for a given word, they are not well …

Plasma Steroid Hormones In Loggerhead And Green Sea Turtle Hatchlings, Andrea Reis

Electronic Theses and Dissertations 2010 - 2019

Florida’s sea turtle populations are increasing due to conservation efforts; however, sea turtle species are vulnerable to climate change. Turtles exhibit temperaturedependent sex determination, in which nest environment influences sex. Environmental changes may produce altered sex ratios that limit reproduction potential; therefore hatchling sex ratios should be monitored. Hatchlings are not externally sexually dimorphic, making sex identification difficult. This study established baseline plasma hormone concentrations in hatchling and post-hatchling green (Chelonia mydas) and loggerhead (Caretta caretta) sea turtles using High Performance Liquid Chromatography. Five hormones were assayed and were present in the majority of samples (testosterone: N.D.-10.12, progesterone: N.D.-0.43, estradiol: …

Monitoring Cryptic Amphibians And Reptiles In A Florida State Park, Richard M. Engeman, Walter E. Meshaka Jr., Robert Severson, Mary Ann Severson, Greg Kaufman, N. Paige Groninger, Henry T. Smith

United States Department of Agriculture Wildlife Services: Staff Publications

We monitored cryptic herpetofauna at Savannas Preserve State Park, Florida, by combining artificial cover counts with a quantitative paradigm for constructing and calculating population indices. Weekly indices were calculated from two consecutive days of data collection each week for 7 months from mid-winter to mid-summer in three habitats. Seventeen species were observed at least once, and time trends using index values were followed for six species. Among these, abundance and seasonal pattern information were obtained for an exotic species (greenhouse frog) and a species identified by the Florida Committee on Rare and Endangered Plants and Animals as threatened (Florida scrub …

Is There A Future For Genome-Editing Technologies In Conservation?, J. A. Johnson, R. Altwegg, D. M. Evans, J. G. Ewen, I. J. Gordon, N. Pettorelli, J. K. Young

United States Department of Agriculture Wildlife Services: Staff Publications

In a recent review, Pimm et al. (2015) highlight emerging technologies in protecting biodiversity. While their list is noteworthy, the authors’ exclusion of innovations in genomic research, with the exception of single-species DNA barcoding methods, was surprising given recent advances in genome-editing technology and its potential application to conservation. Taylor & Gemmell (2016) address that deficiency in a subsequent commentary identifying three avenues where emerging genomic technologies have great potential for increasing our ability to conserve biodiversity. Those areas include the use of next-generation sequencing technologies and methods such as RADseq for monitoring genetic diversity, effective population size, and …

A Benefit-Cost Analysis Decision Framework For Mitigation Of Disease Transmission At The Wildlife–Livestock Interface, Stephanie A. Shwiff, Steven J. Sweeney, Julie L. Elser, Ryan S. Miller, Matthew Farnsworth, Pauline Nol, Steven S. Shwiff, Aaron M. Anderson

United States Department of Agriculture Wildlife Services: Staff Publications

The economics of managing disease transmission at the wildlife–livestock interface have received heightened attention as agricultural and natural resource agencies struggle to tackle growing risks to animal health. In the fiscal landscape of increased scrutiny and shrinking budgets, resource managers seek to maximize the benefits and minimize the costs of disease mitigation efforts. To address this issue, a benefit-cost analysis decision framework was developed to help users make informed choices about whether and how to target disease management efforts in wildlife and livestock populations. Within the context of this framework, we examined the conclusions of a benefit-cost analysis conducted for …

Limited Transmission Of Emergent H7n9 Influenza A Virus In A Simulated Live Animal Market: Do Chickens Pose The Principal Transmission Threat?, Angela Bosco-Lauth, Richard A. Bowen, J. Jeffrey Root

United States Department of Agriculture Wildlife Services: Staff Publications

Emergent H7N9 influenza A virus has caused multiple public health and financial hardships. While some epidemiological studies have recognized infected chickens as an important bridge for human infections, the generality of this observation, the minimum infectious dose, and the shedding potential of chickens have received conflicting results. We experimentally tested the ability of domestic chickens (Gallus gallus domesticus) to transmit H7N9 to co-housed chickens and to several other animal species in an experimental live animal market. Results indicated that an infected chicken failed to initiate viral shedding of H7N9 to naIve co-housed chickens. The infected chicken did, however, …

Supplementary Feeding And Endangered Avian Scavengers: Benefits, Caveats, And Controversies, Ainara Cortés- Avizanda, Guillermo Blanco, Travis L. Devault, Anil Markandya, Munir Z Virani, Joseph Brandt, José A Donázar

United States Department of Agriculture Wildlife Services: Staff Publications

Large avian scavengers are among the most vulnerable vertebrates, and many of their populations have declined severely in recent decades. To help mitigate this marked reduction in abundance, supplementary feeding stations (SFS; colloquially termed “vulture restaurants”) have been created worldwide, often without consideration of the scientific evidence supporting the suitability of the practice. SFS have been effective and important tools for conservation and reintroduction of avian scavengers. However, negative consequences can result from large aggregations of individual birds, disrupting intraguild processes and promoting density-dependent decreases in productivity. At the community level, SFS favor the congregation of predators (ie facultative scavengers), …

Review Of Anthraquinone Applications For Pest Management And Agricultural Crop Protection, Shelagh T. Deliberto, Scott J. Werner

United States Department of Agriculture Wildlife Services: Staff Publications

We have reviewed published anthraquinone applications for international pest management and agricultural crop protection from 1943 to 2016. Anthraquinone (AQ) is commonly found in dyes, pigments and many plants and organisms. Avian repellent research with AQ began in the 1940s. In the context of pest management, AQ is currently used as a chemical repellent, perch deterrent, insecticide and feeding deterrent in many wild birds, and in some mammals, insects and fishes. Criteria for evaluation of effective chemical repellents include efficacy, potential for wildlife hazards, phytotoxicity and environmental persistence. As a biopesticide, AQ often meets these criteria of efficacy for the …

American Robins (Turdus Migratorius) And Cedar Waxwings (Bombycilla Cedrorum) Vary In Use Of Cultivated Cherry Orchards, Rachael A. Eaton, Catherine A. Lindell, Jeffrey Homan, George M. Linz, Brian A. Maurer

United States Department of Agriculture Wildlife Services: Staff Publications

Some fruit-eating bird species commonly consume cultivated fruit. Species-specific variation in diet preferences could result in varying use of orchards and impacts on the fruit-producing industry. However, species specific studies of avian orchard use are lacking, particularly throughout the fruit-growing season. Our objectives were to quantify the frequency of daily bird visits to orchards and the amount of time birds spent visiting orchards each day over the fruit-ripening season. Birds are well-documented consumers of cultivated sweet cherries (Prunus avium), which are relatively high in sugar and low in proteins and lipids. American Robins (Turdus migratorius) and …
