Quantifying The Effects Of Boat Wakes On Intertidal Oyster Reefs In A Shallow Estuary, Donna Campbell

Electronic Theses and Dissertations

There have long been concerns about the negative impacts of recreational boating activity in the Indian River Lagoon system (IRL), especially in Mosquito Lagoon (ML), the northernmost part of the IRL. My research is focused on the impacts of boat wakes on intertidal reefs formed by the eastern oyster, Crassostrea virginica. There has been a 24% loss of oyster habitat in ML since 1943, where natural oyster reefs have been replaced by dead oyster reefs which do not serve the same ecological function. While there is anecdotal and correlative evidence that this loss is a result of boat wakes, no …

Enduring Impact Of Childhood Stressors On Adult Health: Testing Psychological And Behavioral Pathways, Tracy Keirns

Doctoral Dissertations

Stress and health has been a topic of interest among researchers in a variety of fields such as medical sociology, psychology, public health, child abuse, and epidemiology. For decades this research had largely been conducted in silos within each of the respective fields. In recent years, these silos have started to diminish. Sociologists have begun to consider the accumulation of stressors over the life course, including how serious childhood stressors (such as child abuse) impact morbidity and mortality later in life. Using Wave I, Wave III and Wave IV data from the National Longitudinal Study of Adolescent to Adult Health …

A Physiocratic Systems Framework For Open Source Agricultural Research And Development, Dorn Cox

Doctoral Dissertations

This dissertation presents a new participatory approach to agricultural research and development. It surveys the biological, sociological, economic, and technical landscape and proposes a framework for adaptive management based on the 18th century Physiocratic school of land-based economics. Industrial specialization and heavy emphasis on deductive approaches to science have contributed to the disconnection of large portions of the population from natural systems. Conventional agriculture and agricultural research methods following this pattern have created expensive social, environmental, and economic external costs, while adaptive management and resilient agricultural systems have been hindered by the cost and complexity of quantifying environmental services. However, …

Survey Of The Charge Properties Of Phospholipids Using Nanodiscs And Membrane-Confined Electrophoresis, Cheng Her

Doctoral Dissertations

Phospholipids (PL) are a major, diverse constituent of cell membranes. PL diversity arises from the nature of the fatty acid chains, as well as the head group structure. The head group charge is thought to contribute to both the strength, and specificity of protein-membrane interactions. Furthermore, the divalent cations Ca2+ and Mg2+, have been shown to be essential for optimal binding for some of these interactions. Because it has been difficult to measure membrane charge, it has been impossible to quantitate the role charge plays in these interactions. However, Nanodiscs provide a stable, planar membrane bilayer suitable for biophysical studies. …

Genetic And Evolutionary Analysis Of Plant Replication Protein A 1 (Rpa1), Behailu Birhanu Aklilu

Doctoral Dissertations

Challenging human health issues include treatments for genetic diseases and providing improved agricultural crop output to feed the growing world population. The project described here, which focuses on how cells respond to chromosomal (genomic) damage, has significant implications in each example. In humans, accumulation of DNA damage induced mutations can result in genetic diseases such as cancer, and in plants can similarly result in genome instability, reducing productivity. Organisms from human to plants have conserved mechanisms to counteract DNA damage. However, detailed genetic and biochemical information on plant DNA repair systems is still limited. The goal of this dissertation was …

Genomic Resource Development And Candidate Gene Evaluation In Fragaria Vesca (L.), Melanie Eileen Shields

Doctoral Dissertations

The wild strawberry Fragaria vesca (L. Rosaceae) is an important diploid model plant system for the study of processes associated with crop production, plant physiology, and cultivar development of the octoploid cultivated strawberry (F. ×ananassa), an economically important crop plant. A fosmid clone library developed from F. vesca ssp. americana ‘Pawtuckaway’, and a mapping population of 96 F2 progeny (YPF2) resulting from a cross of F. vesca ssp. semperflorens “Yellow Wonder’ with F. vesca ssp. americana ‘Pawtuckaway’, were employed to further develop genetic and genomic resources and advance the search for the molecular identity of the classically defined fruit color …

Hybrid Zone Dynamics Between Saltmarsh (Ammodramus Caudacutus) And Nelson's (Ammodramus Nelsoni) Sparrows, Jennifer Walsh

Doctoral Dissertations

Hybrid zones in nature have long been equated to “windows on the evolutionary process” providing unique environments to understand patterns of gene flow and introgression and the role of these mechanisms in maintaining biodiversity. Ongoing hybridization and introgression can lead to a number of conservation and evolutionary outcomes; as such, identifying the role of introgression in natural populations can provide new insights into species interactions while contributing to our understanding of evolutionary theory.

The research presented below characterizes hybrid zone dynamics between two tidal marsh endemics – the Saltmarsh (Ammodramus caudacutus) and Nelson’s (Ammodramus nelsoni) sparrow. Both species co-inhabit salt …

Formal Synthesis Of Cj-12,954 And Cj-13,014 Using Zinc-Mediated Tandem Chain Extension-Aldol Reaction And Synthesis And Investigation Of Diastereoselectivity Of Hydroxy-Cyclopropyl Peptide Isosteres, Yashoda Naga Deepthi Bhogadhi

Doctoral Dissertations

A formal synthesis of the natural products CJ-12,954 and CJ-13,014 was successfully accomplished using the zinc-mediated tandem chain extension-aldol reaction methodology. This chemistry was performed on a chiral β-keto imide synthesized using a DCC coupling reaction. The diastereoselectivity of the aldol reaction was controlled by an Evans chiral auxiliary. Comparison between the reported and experimental spectral data for the spiroketals confirmed the structural assignment.

The diastereoselectivity of the homologation-cyclization-rearrangement-lactonization reaction of β-keto imide derived from phenyl carbamate-protected proline was studied. Tetra-n-butylammonium fluoride-mediated rearrangement of trimethylsilyl cyclopropanol demonstrated the role of chiral auxiliary and the amino acid stereocenter in controlling the …

Development Of An Isotopic Approach For Detailing Heparin Sequences, Qing Guo

Doctoral Dissertations

Heparin/heparin sulfates are carbohydrate polyionic polymers that participate in a host of critically important biological processes such as blood anticoagulation, pathogen infection, cell differentiation, growth, migration and inflammation, to mention a few. A century has passed since heparin’s initial discovery with a fair understanding of its overall composition. Unfortunately, there has been no structural work at the detailed chemical level that might support a synthetic effort. In this study, I utilize a chemical derivatization strategy (dual permethylation) that imparts isotopic structural specificity, which can be followed by step-wise disassembly in an ion trap mass spectrometer, (MSn). A set of analytical …

The Application Of Analytical Ultracentrifugation With Fluorescence Detection System To The Study Of Macromolecular Complexes In Biological Systems, Wen Xi

Doctoral Dissertations

Using the novel technique of analytical ultracentrifugation with fluorescent detection (AU-FDS), I have conducted the analysis of the properties of two types of intracellular macromolecular complexes: the translational mRNP complex and the intermediate soluble aggregates present in Huntington’s disease. With AU-FDS it is possible to differentiate a broad size range of soluble molecules from complex mixtures and determine the size and abundance of each individual complex based on its sedimentation rate under a centrifugal field.

In the first part of my thesis, the characteristics of the translational repressor SBP1 was determined by analyzing the mRNP complexes it was associated with. …

Unraveling Depositional And Diagenetic Signals In Magnetic Susceptibility In Methane-Bearing Sediments Along The Indian, Cascadia, And Japanese Margins, Stephen C. Phillips

Doctoral Dissertations

Magnetic susceptibility is a bulk measure that reveals variation in ferromagnetic mineral content. High-resolution measurement of magnetic susceptibility in ocean drilling records reveals variability that can be attributed to primary depositional processes and/or secondary diagenetic processes that occur after deposition. Each chapter of my dissertation investigates magnetic susceptibility records along with geochemical, mineralogical, and rock magnetic techniques in methane-bearing marine sediments along the Indian, Cascadia, and Japanese margins. The overall goal of this work is to improve the understanding of the effects of detrital and biogeochemical processes on magnetic mineralogy, and thus magnetic susceptibility, in these continental margin marine environments. …

Single Chain Technology: Toward The Controlled Synthesis Of Polymer Nanostructures, Christopher Kenneth Lyon

Doctoral Dissertations

A technique for fabricating advanced polymer nanostructures enjoying recent popularity is the collapse or folding of single polymer chains in highly dilute solution mediated by intramolecular cross-linking. We term the resultant structures single-chain nanoparticles (SCNP). This technique has proven particularly valuable in the synthesis of nanomaterials on the order of 5 – 20 nm. Many different types of covalent and non-covalent chemistries have been used to this end.

This dissertation investigates the use of so-called single-chain technology to synthesize nanoparticles using modular techniques that allow for easy incorporation of functionality or special structural or characteristic features. Specifically, the synthesis of …

Catch Share Management In The Northeast Multispecies Fishery: Implications For The Commercial Groundfish Fishery In New Hampshire, Rachel G. Feeney

Doctoral Dissertations

This dissertation tests theories about catch share approaches to fishery management, examining their validity and limits relative to the Northeast groundfish sector program, and potentially modifies them in light of research outcomes. Participants of the groundfish fishery based in New Hampshire are the particular focus of research, but broader impacts are considered. Studies of this catch share program have been limited to date, and studies of catch share programs generally have focused on a particular dimension (e.g., biological, social, economic) rather than integrate across dimensions, despite increasing needs to do so for management. Here, six key aspects of fishing are …
