Acoustic Analysis Of Saproxylic Arthropod Diversity In North And Central American Pine Forests, Kristy Marie Mcandrew
Acoustic Analysis Of Saproxylic Arthropod Diversity In North And Central American Pine Forests, Kristy Marie Mcandrew
Theses and Dissertations
Biodiversity of arthropods living in dead wood is often understudied despite their potential effects on ecological processes such as wood decomposition and nutrient cycling. More time-efficient and less destructive methods are needed to study these saproxylic organisms to fully understand their global diversity. Because ecoacoustic methods have never been applied to saproxylic communities before, field and analytical methods such as waveguides, and soundproofing were developed, tested, and optimized. After developed methods were implemented in the field, Pearson's correlation tests were conducted to compare ecoacoustic index performance to traditional biodiversity indices. We found five significant correlations, all of which occurred at …

Interactions Between Aedes Albopictus (Skuse 1894) And Mycobacterium Ulcerans, Jillian Masters
Theses and Dissertations
Mycobacterium ulcerans is an acid-fast bacillus that is the causative agent of Buruli ulcer, a necrotizing skin disease. The transmission route for M. ulcerans is unknown, but many insects have been posited as part of the web, including Belostomatids, Naucorids, and Culicids. Aedes albopictus was selected for use in a set of experiments where the first-generation larvae were inoculated with M. ulcerans, and mosquitoes were reared throughout the third generation to interrogate presence and quantity of the bacteria. Using qPCR, second and third generations displayed positivity (22% and 5.6% respectively). 16S V4 sequencing was used to obtain microbiota for all …

Pharmacokinetics And Pharmacodynamics Of Dexmedetomidine In Horses, Sarah E. Shane
Pharmacokinetics And Pharmacodynamics Of Dexmedetomidine In Horses, Sarah E. Shane
Theses and Dissertations
An ideal dexmedetomidine protocol has yet to be determined for standing sedation in horses. It was hypothesized that an intravenous (IV) bolus followed by continuous rate infusion (CRI) dexmedetomidine would have a quicker increase in plasma concentrations compared to repeated intramuscular (IM) injections. In a cross-over design, eight adult, female horses were randomly placed in two groups: the CRI group (IV bolus dexmedetomidine at 0.005 mg/kg followed by a CRI at 0.01 mg/kg/hr for 15 minutes then 0.005 mg/kg/hr for 60 minutes) and the IM group (dexmedetomidine at 0.01 mg/kg, followed by 0.005 mg/kg in 30-minute intervals for 60 minutes). …

Assessing Effects Of Habitat Amount Vs. Configuration On Avian Diversity In Managed Pine Landscapes, Craig Sklarczyk
Assessing Effects Of Habitat Amount Vs. Configuration On Avian Diversity In Managed Pine Landscapes, Craig Sklarczyk
Theses and Dissertations
Understanding how habitat amount and configuration affect species richness, occurrence or abundance has been one of the major foci of research in ecology and biogeography, given its central importance for conservation planning and landscape management. We conducted bird point counts within clearcuts and mature pine stands of different sizes and configuration in working pine forest in north-central Mississippi to determine species associations. Early-successional and mature pine focal species showed varying response to the proportion and proximity of vegetation conditions in the landscape. While elements of configuration exhibited a greater influence on predicted avian abundance in this landscape, meaning many species …
The Role Of The Endocannabinoid System In Immune Homeostasis With An Emphasis On The Immune Effects Of Carboxylesterase Inhibition By Chlorpyrifos In Murine Lung Tissue, Brittany Nichole Szafran
The Role Of The Endocannabinoid System In Immune Homeostasis With An Emphasis On The Immune Effects Of Carboxylesterase Inhibition By Chlorpyrifos In Murine Lung Tissue, Brittany Nichole Szafran
Theses and Dissertations
The endocannabinoid system is composed of endocannabinoids (eCBs), their cognate receptors, and their biosynthetic and catabolic enzymes. Inhibition of serine hydrolases (catabolic enzymes), such as carboxylesterases (CES), might result in the accumulation of eCBs. eCBs, such as 2-arachidonoylglycerol (2-AG), have been shown to increase or reduce inflammation via engagement with cannabinoid receptors on immune cells. This research focuses on exploring the ability of eCBs and their metabolizing enzymes to regulate inflammation. First, a negative feedback mechanism between inflammation and the eCB system was examined by identifying serine hydrolases inhibited by lipopolysaccharide (LPS) stimulation in mice. Ces2g activity was inhibited and …
Sperm Functional Genome And Epigenome Regulating Bull Fertility And Sperm Freezability, Muhammet Rasit Ugur
Sperm Functional Genome And Epigenome Regulating Bull Fertility And Sperm Freezability, Muhammet Rasit Ugur
Theses and Dissertations
Artificial insemination (AI) using cryopreserved sperm has an important positive impact on cattle production. Fertility is the most critical trait controlling livestock production; however, molecular, cellular, and physiological determinants of bull fertility and sperm freezability are not well understood. Better understanding of molecular, cellular, and physiological underpinnings of bull fertility may increase the success rate of AI. The objective of this study was to test the hypothesis that expression dynamics of sperm nuclear proteins, post-translational modifications (PTM) of sperm Histone 4 (H4), and seminal plasma metabolome are associated with bull fertility and sperm freezability (P = 0.043). Flow cytometry experiments …
Influence Of Boat Activity On Wave Climate In Back Bay Of Biloxi, Ms, Matthew Virden
Influence Of Boat Activity On Wave Climate In Back Bay Of Biloxi, Ms, Matthew Virden
Theses and Dissertations
Wave energy is a major driver for many coastal processes and influences wetland vegetation and shoreline stability. Coastal conservation and restoration projects often include wave climate estimations in the decision-making process for project design. The current method primarily used to estimate a project area's wave climate is the use of wind-wave models. These models use wind speed, wind direction, bathymetry, and fetch to estimate site-specific wave activity. However, these models neglect boat wake which is an important contributor to wave energy in fetch-limited environments. This study used site-specific wave measurements to compare wind-protected and open sites in Back Bay, Mississippi. …
The Influenza Ribonucleoprotein Complex And Its Impact On Viral Replication And Evolution, Kaitlyn Waters
The Influenza Ribonucleoprotein Complex And Its Impact On Viral Replication And Evolution, Kaitlyn Waters
Theses and Dissertations
The ribonucleoprotein (RNP) complex of influenza A viruses (IAVs) is responsible for replication and transcription of viral RNA and genome, respectively. Mutations in the RNP genes have been identified to play a role in host adaptations and tissue tropisms of IAVs, and compatibility among these genes has been implicated as an important factor for facilitating reassortment of IAVs. Furthermore, mutations and reassortment can drastically impact the polymerase activities of the RNP complex in vitro. However, the simultaneous role both of these mechanisms play in enhancing or diminishing polymerase activities of divergent IAVs remains opaque, and therefore, a greater understanding of …
Occupied: The Civilian Experience In Montélimar, 1939-1945, Cameron Zinsou
Occupied: The Civilian Experience In Montélimar, 1939-1945, Cameron Zinsou
Theses and Dissertations
The vast literature of World War II in France contains a major gap. There is little on the daily life of civilians prior to France's defeat during the Battle of France or civilian life after the liberation of France from the German occupier. Most literature on France during the war focuses on the Vichy years from 1940-1944. This dissertation extends the timeline to encapsulate the whole war from 1939-1945. By doing so, historians can uncover other themes central to the French civilian experience besides the German presence. This dissertation shows the benefits of this chronological extension through its investigation of …

Thinking And Talking About Kinds, Ye Ji Seoung
Theses and Dissertations
Three experiments investigated whether definite singular generics (e.g., the dog barks) require that the kind does not contain multiple subkinds. No effect of generic form was found in experiment 1 and 3. However, experiment 2 found people thought there were fewer subkinds when definite singulars referred to the kind.
The Impact Of Location And Time Of Day On The Expression Of Social And Physical Maintenance Behaviors In Wild Asian Elephants (Elephas Maximus) In Thailand, Summer Fiori
Theses and Dissertations
Much of what we know about Asian elephant (Elephas maximus) behavioral ecology is the result of long-term ethological studies on wild elephants in India and Sri Lanka or experimental research on captive elephant behavior and cognition. While it is important to study the behavior and ecology of elephants to understand the evolution of adaptations that have made them well-suited for their natural environments, there is also a growing need to study populations of wild Asian elephants for applied conservation purposes. More specifically, elephants are endangered and are facing increasing threats such as human-elephant conflict. In this study, behavioral data …

A Nonhuman Primate Model Of The Out Of Africa Theory Utilizing Chinese- And Indian-Derived Rhesus Macaques (Macaca Mulatta), Jacob N. Hunter
Theses and Dissertations
Evidence suggests that certain genotypic variants associated with novelty-seeking and aggressiveness, such as the 7-repeat dopamine D4 receptor variant (DRD4-7R), short (s) allele of the serotonin transporter (5-HTT), and the low-activity variant of the MAOa promoter (MAOa-L), are more prevalent in human groups that radiated out of Africa than human groups that remained in Africa. Rhesus macaques (Macaca mulatta), like humans, are a widespread species of primates that needed to adapt to different regional environments with one group, Indian-derived rhesus macaques, largely occupying predictable and resource-rich environments, while the other group, the Chinese-derived rhesus macaques, has come to occupy less …

Body States Of Asian Elephants Within And Around Protected Areas In The Salakpra Wildlife Sanctuary, Kanchanaburi, Thailand, Caitlyn Thai
Theses and Dissertations
Researchers are becoming increasingly aware that studying a species’ landscape of fear or, more broadly, their emotional states, can better inform cognitive questions about how animals navigate their environments. Vigilance behaviors are one way to determine how certain species perceive and respond to risky situations. Due to rapid environmental change, large animals such as elephants are experiencing risky encounters with humans more often than ever before. This study aims to investigate Asian elephants’ expressions of body states and how they might regulate their behavior based on perceived environmental risk or change. Specifically, we investigated the behavioral responses of Asian elephants …

Theses and Dissertations
Naked Mole Rats (NMR) and their close relative the Damaraland Mole Rat are the only eusocial mammals. This study investigated whether NMR juveniles engage in play-like behavior within a crèche chamber in a laboratory colony and whether the frequent interruption of juvenile social interactions by adults suppress social play. One colony at the College of Staten Island, CUNY, was observed over the course of six months. An ethogram based on the NMR literature was used to code juvenile behavior in the crèche chamber one to two times a week for a total of thirty video sessions ~ 25-40 minutes in …
Effectiveness Of A Novel Paradigm Examining The Impact Of Phubbing On Attention And Mood, Kimberly Marynowski
Effectiveness Of A Novel Paradigm Examining The Impact Of Phubbing On Attention And Mood, Kimberly Marynowski
Theses and Dissertations
Human beings are social in nature, but what happens when a tool used to facilitate social interaction instead acts as a disruptor? “Phubbing” describes everyday interruptions in social interactions that occur due to mobile device use (e.g., texting, receiving calls; Chotpitayasunondh & Douglas, 2018). Little is known about how phubbing influences our cognitive and emotional functioning. The aim of the present study is to explore the initial effectiveness of a novel experimental manipulation of phubbing during a joint problem-solving task, evaluate its impact on mood and anxiety-related attention bias, and explore the moderating role of trait anxiety and phubbing induced …
Tessellated Pictures And Traditional Piety, Matthew K. Higham
Tessellated Pictures And Traditional Piety, Matthew K. Higham
Theses and Dissertations
Nearly 300 years before the rise of a ‘Christianized,’ Eastern Roman Empire, generations of inhabitants in the Eastern Mediterranean and Near East had witnessed a considerable variety and evolution of religious thought. As a result of the expansion of Christian sects throughout the Near East and Mediterranean, in 325 CE, Emperor Constantine I convened a theological council to unite his vast kingdom in the East under a single religious creed. While revisions to the text of the first ‘Nicene Creed’ and subsequent councils would be organized, many dissenting factions refused to relinquish their long-held beliefs and traditions. Some of these …
Redemption Through Representation: Grace Carpenter Hudson And Her Portraits Of American Indian Children, Meagan Camille Anderson
Redemption Through Representation: Grace Carpenter Hudson And Her Portraits Of American Indian Children, Meagan Camille Anderson
Theses and Dissertations
In his 1978 biography of Grace Carpenter Hudson, Searles R. Boynton refers to the artist as "the best in California," praising her life-long dedication to depicting the Pomo children of Northern California. During her lifetime (1865-1937), Hudson's work traveled to museums, world fairs, and expositions across the United States. The purpose of this research is to assert that Hudson's work is evidence of, and a response to, turn-of-the-twentieth-century Euro-Americans' hopes that the American Indian child could be "redeemed," or "saved," from their "savage" or "undomesticated" past. Additionally, this paper aims to convince the reader of the significance of Hudson’s art …

Imago Clipeata, The Liturgy, And Giovanni Pisano's Man Of Sorrows Lectern: A Classical Reappropriation In The Gothic Era, Joslyn Elise Ableman
Theses and Dissertations
The monumental sculpture, especially the pulpits, of the father and son duo, Nicola and Giovanni Pisano, have often been compared to ancient Roman and early Christian sarcophagi. Giovanni produced a pulpit with two accompanying lecterns for the Pisa Cathedral, which is just a few steps away from the Camposanto, a “holy field”, or cemetery, built around sacred soil from Golgotha which serves to house a huge collection of sarcophagi. Iconography, composition, relief style, and even the materiality of Giovanni’s Pisa pulpit is in part governed by, and connected to, these sarcophagi. This influence is especially highlighted by the Epistles lectern, …
Does Subjective Time Cost Explain Cognitive Task Choices?, Raina Ashley Isaacs
Does Subjective Time Cost Explain Cognitive Task Choices?, Raina Ashley Isaacs
Theses and Dissertations
The current literature suggests that subjective time duration could be the common currency used for task choice. However, few studies have been conducted that use non-physical tasks for their task choice options. Thus, the purpose of the current study was to examine if subjective time duration is the common currency for task choice regardless of task type. Participants first provided their subjective time estimates for each of the perceptual-motor and cognitive tasks that have been a priori determined to be at the medium difficulty level. Two cognitive tasks (item generation and math problem task) and one perceptual-motor task with a …
