Feelings Of Connectedness To Nature: A Comparison Of Park & Recreation Management Students And Sport Management Students., N. E. Scarborough

Undergraduate Honors Theses

In the face of the present consumer-based environmental movement, leaders in many industries and disciplines are striving to understand why people are “going green” in order to market to them. Researchers have been studying ways in which people connect to the environmental movement, and researchers in the field of sport and recreation are also conducting such studies. Several surveys have been developed to measure these connections; one such survey instrument is the Connectedness to Nature Scale (CNS). In the present study, the CNS was re-created online, and a link to the survey was sent via email to students studying Park …

Cellular Roles Of Dna Polymerase Beta, Sreerupa Ray, Miriam-Rose Menezes, Ali Senejani, Joann Balazs Sweasy

Biology and Environmental Science Faculty Publications

Since its discovery and purification in 1971, DNA polymerase ß (Pol ߆) is one of the most well-studied DNA polymerases. Pol ß is a key enzyme in the base excision repair (BER) pathway that functions in gap filling DNA synthesis subsequent to the excision of damaged DNA bases. A major focus of our studies is on the cellular roles of Pol ß. We have shown that germline and tumor-associated variants of Pol ß catalyze aberrant BER that leads to genomic instability and cellular transformation. Our studies suggest that Pol ß is critical for the maintenance of genomic stability and that …

Certain Agave Species Exhibit The Capability To Be Moderately Productive Under Conditions Of High Salt And Drought Stress, Steven J. Bergsten Dec 2013

Certain Agave Species Exhibit The Capability To Be Moderately Productive Under Conditions Of High Salt And Drought Stress, Steven J. Bergsten

Theses and Dissertations

Water availability and arable lands are increasingly limiting resources in many parts of the U.S., particularly in semi-arid and arid regions. As a means of addressing food and fuel demands associated with burgeoning population growth, highly productive and water-use efficient crops need to be identified. One potential crop, Agave, merits consideration and evaluation due to its putative capability to provide sustenance and energy despite growing in water-limited regions and on marginal soils. However, little is known regarding the productivity these succulent plants will have under growing conditions of the Southwest, where high concentrated saline soils are abundant, and water is …

Toward Target 2 Of The Global Strategy For Plant Conservation: An Expert Analysis Of The Puerto Rican Flora To Validate New Streamlined Methods For Assessing Conservation Status, James S. Miller, Gary A. Krupnick, Hannah Stevens, Holly Porter-Morgan, Brian Boom, Pedro Acevedo-Rodríguez, James Ackerman, Duane Kolterman, Eugenio Santiago, Christian Torres, Jeanine Velez

Publications and Research

Target 2 of the 2020 Global Strategy for Plant Conservation (GSPC) calls for a comprehensive list of the world's threatened plant species. The lack of such a list is one of the greatest impediments to protecting the full complement of the world's plant species, and work to achieve this has been slow. An efficient system for identifying those species that are at risk of extinction could help to achieve this goal in a time frame sensitive to today's conservation needs. Two systems that efficiently use available data to assess conservation status were tested against a provisional International Union for Conservation …

Mitochondrial Dysfunction And Reactive Oxygen Species In Neurodegeneration, Leah Farina Dec 2013

Mitochondrial Dysfunction And Reactive Oxygen Species In Neurodegeneration, Leah Farina

Honors Theses

Neurodegeneration leads to the loss of normal anatomy and physiology of the neuronal system in a human body. The hallmark of most neurodegenerative diseases is abnormal folding and accumulation of proteins within neuronal cell bodies that is not present in healthy people. These changes in normal protein metabolism often lead to neuronal cell death and failure of the affected regions of the central nervous system. Abnormal protein accumulation may be attributed to dysfunctional mitochondria and damage by reactive oxygen species. In addition to causing altered protein accumulation, dysfunctional mitochondria and an excess of reactive oxygen species also lead to errors …

Land Grabs And Implications On Food Sovereignty And Social Justice In Senegal, Joanna Lafrancesca Dec 2013

Land Grabs And Implications On Food Sovereignty And Social Justice In Senegal, Joanna Lafrancesca

Master's Theses

This thesis focuses on the case study of Senegal to examine the implications of large- scale land acquisitions on the livelihoods of small-scale farmers. I investigate the diverse perspectives of market enthusiasts, human rights organizations, peasants, the state, and international financial organizations on large-scale land acquisitions. Based on primary research, I argue that the state of Senegal plays an active role in permitting “land grabs” and that they pose a threat to food sovereignty among Senegalese host communities. Lastly, I argue there needs to be a broader understanding of long-term consequences and risks to insure social justice in areas affected …

Fumarate Inhibits Tnf-Α Release, Megan Kelly Dec 2013

Fumarate Inhibits Tnf-Α Release, Megan Kelly

Seton Hall University Dissertations and Theses (ETDs)

Vertebrates utilize two forms of immunity to combat pathogens. Innate immunity is considered the first line of defense that utilizes immediate action and three barriers. Innate immunity responses typically occur within minutes of pathogen exposure resulting in cellular receptor activation and acute pro-inflammatory cytokine release. Inflammatory macrophages engage bacterial endotoxins, including Gram-negative lipopolysaccharide (LPS) and Gram-positive lipoteichoic acid (LTA). And respond by releasing tumor necrosis factor-α (TNF-α). While beneficial for neutralizing acute pathogen exposure, prolonged TNF-α release results in chronic inflammation and tissue damage. In the present study, we examined two methylated derivatives of a citric acid cycle intermediate, fumarate, …

Biochemical Assay Optimization And Computational Screening Efforts To Identify Potential Luxs Inhibitors, Keeshia Q. Wang Dec 2013

Biochemical Assay Optimization And Computational Screening Efforts To Identify Potential Luxs Inhibitors, Keeshia Q. Wang

Master's Theses

Quorum sensing (QS) is a process of coordination of bacterial gene expression in response to cell population. System two QS is regulated by the small signaling molecule autoinducer-2 (AI-2) and is implicated in the infectious behaviors of various bacterial species. AI-2 is biosynthesized from S-ribosylhomocysteine (SRH) by the enzyme LuxS and induces interspecies cell-to-cell communication. Inhibition of LuxS would therefore inhibit interspecies QS. Herein, a search for novel molecular species that will competitively bind with SRH in the LuxS binding site is performed in silico. Computational screening results are then validated in vitro using an optimized LuxS inhibition …

Molecular Evolution Of Protein-Rna Mimicry As A Mechanism For Translational Control, Assaf Katz, Lindsey Solden, S. Betty Zou, William Wiley Navarre, Michael Ibba Dec 2013

Molecular Evolution Of Protein-Rna Mimicry As A Mechanism For Translational Control, Assaf Katz, Lindsey Solden, S. Betty Zou, William Wiley Navarre, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Elongation factor P (EF-P) is a conserved ribosome-binding protein that structurally mimics tRNA to enable the synthesis of peptides containing motifs that otherwise would induce translational stalling, including polyproline. In many bacteria, EF-P function requires post-translational modification with (R)-β-lysine by the lysyl-tRNA synthetase paralog PoxA. To investigate how recognition of EF-P by PoxA evolved from tRNA recognition by aminoacyl-tRNA synthetases, we compared the roles of EF-P/PoxA polar contacts with analogous interactions in a closely related tRNA/synthetase complex. PoxA was found to recognize EF-P solely via identity elements in the acceptor loop, the domain of the protein that interacts with the …

Functional Environmental Screening Of A Metagenomic Library Identifies Stla; A Unique Salt Tolerance Locus From The Human Gut Microbiome, Roy D. Sleator, Et. Al. Dec 2013

Functional Environmental Screening Of A Metagenomic Library Identifies Stla; A Unique Salt Tolerance Locus From The Human Gut Microbiome, Roy D. Sleator, Et. Al.

Department of Biological Sciences Publications

Functional environmental screening of metagenomic libraries is a powerful means to identify and assign function to novel genes and their encoded proteins without any prior sequence knowledge. In the current study we describe the identification and subsequent analysis of a salt-tolerant clone from a human gut metagenomic library. Following transposon mutagenesis we identified an unknown gene (stlA, for “salt tolerance locus A”) with no current known homologues in the databases. Subsequent cloning and expression in Escherichia coli MKH13 revealed that stlA confers a salt tolerance phenotype in its surrogate host. Furthermore, a detailed in silico analysis was also …

Identification Of The Binding Partners For Hspb2 And Cryab Reveals Myofibril And Mitochondrial Protein Interactions And Non-Redundant Roles For Small Heat Shock Proteins, Kelsey Murphey Langston

Theses and Dissertations

Small Heat Shock Proteins (sHSP) are molecular chaperones that play protective roles in cell survival and have been shown to possess chaperone activity. As such, mutations in this family of proteins result in a wide variety of diseases from cancers to cardiomyopathies. The sHSPs Beta-2 (HspB2) and alpha-beta crystalline (CryAB) are two of the ten human sHSPs and are both expressed in cardiac and skeletal muscle cells. A heart that cannot properly recover or defend against stressors such as extreme heat or cold, oxidative/reductive stress, and heavy metal-induced stress will constantly struggle to maintain efficient function. Accordingly, CryAB is required …

Nonlinear Spectroscopic Investigation Of Adsorption To C-18 Model Stationary Phase, Anthony D. Peterson Dec 2013

Nonlinear Spectroscopic Investigation Of Adsorption To C-18 Model Stationary Phase, Anthony D. Peterson

Theses and Dissertations

Reversed-phase liquid chromatography (RPLC) is a commonly used separation technique in chemistry. Nevertheless, the mechanistic interactions at the molecular level among the eluent, analyte, and the stationary phase are not fully understood. Because of this limited understanding, optimization of the separation must be done experimentally. Learning more about molecular interactions should aid in improving separations. We are currently using second-harmonic generation (SHG) spectroscopy to investigate how analytes adsorb to the surface. SHG is a spectroscopic technique that produces signal only at places of non-isotropic symmetry; this typically occurs at surfaces. SHG can be used to produce surface isotherms of test …

Life In Groups: The Roles Of Oxytocin In Mammalian Sociality, Allison M.J. Anacker, Annaliese K. Beery

Psychology: Faculty Publications

In recent decades, scientific understanding of the many roles of oxytocin (OT) in social behavior has advanced tremendously. The focus of this research has been on maternal attachments and reproductive pair-bonds, and much less is known about the substrates of sociality outside of reproductive contexts. It is now apparent that OT influences many aspects of social behavior including recognition, trust, empathy, and other components of the behavioral repertoire of social species. This review provides a comparative perspective on the contributions of OT to life in mammalian social groups. We provide background on the functions of OT in maternal attachments and …

Evolution And Functional Morphology Of The Cephalic Lobes In Batoids, Samantha Lynn Mulvany Dec 2013

Evolution And Functional Morphology Of The Cephalic Lobes In Batoids, Samantha Lynn Mulvany

USF Tampa Graduate Theses and Dissertations

Cephalic lobes are unique structures derived from the anterior pectoral fins, found in select myliobatid stingrays. Many benthic batoids utilize undulatory locomotion and use their pectoral fins for both locomotion and prey capture. Pelagic myliobatids that possess cephalic lobes utilize oscillatory locomotion, using their pectoral fins to locomote and their cephalic lobes for prey capture. Despite differences in habitat usage and locomotor modes, these batoids feed on very similar benthic organisms. The purpose of this study was to 1.) compare the morphology of the cephalic lobes and anterior pectoral fins in lobed and lobeless species, looking at skeletal elements, musculature …

Use Of Irf-3 And/Or Irf-7 Knockout Mice To Study Viral Pathogenesis: Lessons From A Murine Retrovirus-Induced Aids Model, Megan A. O'Connor, William R. Green Dec 2013

Use Of Irf-3 And/Or Irf-7 Knockout Mice To Study Viral Pathogenesis: Lessons From A Murine Retrovirus-Induced Aids Model, Megan A. O'Connor, William R. Green

Dartmouth Scholarship

Interferon regulatory factor (IRF) regulation of the type I interferon response has not been extensively explored in murine retroviral infections. IRF-3(-/-) and select IRF-3/7(-/-) mice were resistant to LP-BM5-induced pathogenesis. However, further analyses strongly suggested that resistance could be attributed to strain 129-specific contamination of the known retrovirus resistance gene Fv1. Therefore, caution should be taken when interpreting phenotypes observed in these knockout mice, as strain 129-derived genetic polymorphisms may explain observed differences.

The Evolution Of Floral Symmetry Across The Plant Order Lamiales, Jinshun Zhong Dec 2013

The Evolution Of Floral Symmetry Across The Plant Order Lamiales, Jinshun Zhong

Dissertations

Bilaterally symmetrical corollas have evolved independently numerous times from radially symmetrical ancestors and are thought to represent adaptation to specific pollinators. However, evolutionary losses of bilateral symmetry have occurred sporadically in different lineages. CYC2-like and RAD-like are genes needed for the normal development of bilateral symmetry in snapdragon corollas. However, exactly how changes in the floral symmetry patterning genes correlate with the origin and loss of floral bilateral remains poorly known. To address this question, a densely sampled phylogeny of CYC2-like genes across the order Lamiales was inferred and calibrated. The expression patterns of these genes in early diverging and …

Observing The Unwatchable Through Acceleration Logging Of Animal Behavior, Danielle D. Brown, Roland Kays, Martin Wikelski, Rory Wilson, A. Peter Klimley

Methodology and Animal Models in Research

Behavior is an important mechanism of evolution and it is paid for through energy expenditure. Nevertheless, field biologists can rarely observe animals for more than a fraction of their daily activities and attempts to quantify behavior for modeling ecological processes often exclude cryptic yet important behavioral events. Over the past few years, an explosion of research on remote monitoring of animal behavior using acceleration sensors has smashed the decades-old limits of observational studies. Animal-attached accelerometers measure the change in velocity of the body over time and can quantify fine-scale movements and body postures unlimited by visibility, observer bias, or the …

Understory Vegetation Response To Mechanical Mastication Of Piñon And Juniper Woodlands, Jordan Ann Bybee

Theses and Dissertations

Piñon and juniper encroachment and infilling can alter ecosystem processes and decrease resilience and resistance in sagebrush grasslands. Land managers employ a variety of techniques to eliminate these trees and mitigate their negative effects. Mechanical mastication or shredding is an increasingly popular method of removing these trees in Utah. It is a versatile treatment that can reduce canopy fuels, increase infiltration, and reduced sediment loss. We compared vegetation cover for annual and perennial vegetation functional groups on shredded and adjacent unshredded areas across a range of sites. Our approach was to categorize sites by ecological site type (encroachment or tree) …
