Bird Window Strikes On A College Campus: Mortality Estimates And Possible Mitigation, Antarius D. Mclain

College of Graduate Studies: Theses & Dissertations

Understanding the impact that human development has on wildlife populations is essential to preserving biodiversity. Bird populations are a good indicator of anthropogenic threats because they are sensitive to environmental change. Window strikes are a major source of mortality for bird populations. Studies have begun to monitor factors that cause window strikes and estimate the amount of birds killed annually by strikes. However, these estimates can be greatly affected by site dependent variables and scavenging of carcasses. My study addresses this issue by answering four questions: First, how many birds are killed annually on campus? Second, what factors complicate making …

Synthesis Of N-Heterocyclic Molecules And Their Applicability Towards Ion Sensing: Polymeric Chemosensors, Aikohi M. Ugboya

College of Graduate Studies: Theses & Dissertations

Critical to biological and environmental processes are anions because often times their relative concentration in our body can be an indicator of one’s well-being. Therefore, highly sensitive and cost-efficient methods for ions recognition is necessary for human health. In recent times, polymeric chemosensors have become a vital tool for sensing ions because of its higher sensitivity and good mechanical properties compared to their monomeric counterparts. These sensors are designed to produce a measurable response in the presence of a targeted ion such as an electrochemical or optical signal. The unique structure and the photophysical properties of the 1,2,3-triazole core coupled …

Effects Of Climate Variability: A Long-Term Perspective On Leaf Litter Processing In The Ogeechee River, Jose A. Sanchez

College of Graduate Studies: Theses & Dissertations

The Intergovernmental Panel for Climate Change (IPCC) predicts a rise in temperatures and changes to precipitation patterns for the 21^st century. These changes are expected to lead to a higher frequency of extreme events such as drought and floods which lead to the alteration of the hydrology, communities, and processes of freshwater ecosystems. Leaf litter decomposition in stream ecosystems is an important component of the energy and nutrient cycle representing a food source for aquatic organisms. This has made it a tool for assessing long term responses to disturbance due to changes in the assemblage of macroinvertebrates that …

Effect Of Group Size On The Activity Budget Of Two Captive Chimpanzees (Pan Troglodytes), Kaeley Sullins

All Master's Theses

Captive facilities housing chimpanzees are required to provide adequate care and provisions such as dietary, social, and environmental enrichment to promote the psychological well-being of the apes in their care. Chimpanzees are social creatures and changes in groups as well as relocation to a facility with new social partners, can impact each individual chimpanzee’s welfare. By tracking each chimpanzee’s activity budgets, managers can assess welfare and make improvements or adjustments if necessary. I looked at the activity budgets of two captive chimpanzees after the death of a group member and the two chimpanzees’ subsequent relocation to a novel, more socially …

Extending The Morpheme Order Studies: Acquisition Of Modal And Non-Modal Verbal Morphemes By Esl Learners, Amal Alshehry

All Master's Theses

The morpheme order studies have long prevailed in the field of second language acquisition. However, these studies are often undermined by their extent and focus on a limited number of morphemes. Thus, the present study extends the scope of morphemes to include modal verbs within other verbal morphemes and studies the order of their acquisition. Discourse Completion Tests (DCTs) were used to examine a total of twenty-seven ESL learners from a wide range of L1 backgrounds: Japanese, Arabic, Chinese, Thai, Spanish, Turkish, Urdu, and Vietnamese. The study reveals a universal pattern in ESL learners’ acquisition of English verb morphology. …

Measuring Trace Element Concentrations In Artiodactyl Cannonbones Using Portable X-Ray Fluorescence, Joshua L. Henderson

All Master's Theses

Artiodactyl bones are the most common faunal remains found in Washington prehistoric archaeology sites, but they are often too fragmented to accurately identify a family, genus, or species. Traditional faunal analysis can only organize unidentifiable bone fragments into size class, and chemical methods often require the destruction of bone samples. In this thesis research, I tested a new, nondestructive faunal analysis technique using portable X-ray fluorescence (pXRF) to measure trace element concentrations in comparative collection and archaeological bone samples. Using cannonbones from five different artiodactyl species, I collected trace element data from 50 comparative collection specimens and 18 archaeological specimens …

Excavations At The Seila Pyramid And Ritual Ramifications, Kerry Muhlestein

Faculty Publications

In modern times it was not apparent that the structure many travelers had seen atop the remote escarpment in Gebel El-Rus was actually a pyramid. Before its excavation it was locally known as el-Qalah, meaning “the fortress,” though it has since come to be called Harem Seila, or the Seila Pyramid. Even before excavation it could be easily seen as far away as Hawara when the air was clear. Though it stood six miles straight west of the Meidum Pyramid, there was nothing about the visible square covered in aeolian sand that would make explorers or archaeologists think it was …

The Madagascar Research and Conservation Institute (MRCI) is a CBC organization that utilizes volunteers as a data collection resource and workforce for conservation and community outreach initiatives. The current study analyzed data from volunteer experience evaluations (VEE), which included pre- and post-experience self-report surveys comprised of qualitative and quantitative response sections, completed by 45 voluntourists over a three-month span. The quantitative findings indicate that the voluntourist experience improved participants’ self-reported attitudes …

The Activity Budgets Of Captive Javan Gibbons (Hylobates Moloch) And Their Response To Visitor Presence Or Absence, Kalli Kohnen

All Master's Theses

Anthropogenic stress can negatively impact the health of captive animals. Visitors may be a source of stress to captive animals in zoos and sanctuaries. Javan gibbons (Hylobates moloch) are endangered, and healthy captive populations are important to the species’ conservation. The purpose of this study is to assess the impact of visitor presence on the activity budgets of captive Javan gibbons. Using continuous sampling, I recorded the activity budgets of 10 Javan gibbons housed at the Gibbon Conservation Center (GCC) in Santa Clarita, California. I collected data in the mornings, middays, and afternoons on visitor days and non-visitor …

Effects Of Initial Thermal Structure On The Evolution Of Continental Rifting, Alexandra Wernle

All Master's Theses

Continental rifting is a fundamental earth process that displays a wide variety of styles ranging from narrow to wide, symmetric and asymmetric, magmatic and amagmatic. The key conditions and processes that control the evolution of rifts remain enigmatic. Previous research suggests that the initial thermal structure may have a first order control on the evolving styles of these systems. This project examines the impact of the initial thermal structure on the spatial and temporal evolution of continental rifts using finite element thermo-mechanical modeling. The initial thermal structure is a product of crustal heat production rates and heat conducted from the …

Effect Of Carbonaceous Nanoparticles On Naturally Occurring Iron Reduction By Carboxylates, Ashleen Reddy

All Master's Theses

The emission of ambient particulate matter (PM) is regulated by many institutions due to the detrimental effects on health, environment and climate; yet many underlying mechanisms of PM reactivity are still not well understood. In the current study, the effect of carbonaceous nanoparticles (CNPs), contained within ultrafine PM (particle diameter ≤ 100 nm), is investigated on naturally occurring processes that increase the abundance of bioavailable iron. Enhancing iron bioavailability (i) increases primary productivity of iron-limited microorganisms, affecting the carbon cycle and global climate, and (ii) increase toxicity of inhaled particles through the associated production of reactive oxygen species (ROS). Specifically, …

The Chemical Analysis And Biological Activities Of The Secondary Metabolites From Dalea Mollis And Dalea Albiflora, Nicholas Peter Hansen

All Master's Theses

Multidrug resistance has increased since the introduction of drugs used to prevent growth and kill microorganisms in a host. This has caused a worldwide search to discover new drugs effective against microorganisms. Mechanisms of drug resistance include, but are not limited to, the production of biofilms and efflux pumps. Efflux pumps prevent antimicrobial drugs from reaching their biological target, so the coordinated use of efflux pump inhibitors and antimicrobial drugs has been identified as a potential treatment for multidrug-resistant microorganisms. The secondary metabolites of Dalea mollis and Dalea albiflora were tested against multidrug-resistant (MDR) and engineered strains of the fungi …

Exploring Locus Of Control In Offender Cognition And Recidivism Paradigms, Anistasha Lightning, Danielle Polage

All Master's Theses

Working with four Washington State county jails to administer surveys to currently incarcerated inmates, we investigated locus of control and beliefs in the likelihood of continued legal involvement as possible antecedents to criminal recidivism. The surveys examined whether there was any connection between legal involvement frequency and the externalization of locus of control. We investigated external locus of control with specific respect to involvement with the law, the prospect of future incarceration, and feelings concerning the overall cause of original and/or sustained legal involvement utilizing the Revised Causal Dimension Scale (McAuley, Duncan, & Russell, 1992). We identified statistically significant interactions …

The Effect Of Sound On Captive Chimpanzees (Pan Troglodytes), Grace Coffman

All Master's Theses

Sound exposure can have detrimental physiological and psychological effects on humans, but effects on nonhuman primates are not as well understood. Captive chimpanzees are exposed to markedly different acoustic environments than their wild counterparts. This study assessed the organic soundscape of a chimpanzee sanctuary, the Fauna Foundation, in Carignan, Québec, Canada. Noninvasive, observational data collection assessed for frequency of behavior and correlations between chimpanzee behavioral categories, arousal level, and decibel level. Agonistic behavior occurred more frequently in the highest decibel level category. There was a positive correlation between decibel level and arousal level. These findings suggest the need for increased …

Behavior skills training (BST), composed of modeling, instructions, rehearsal, and feedback, is an efficient and commonly used training package that has been proven effective in fostering behavior change in a variety of learners and with a multitude of behaviors, including those related to health and fitness. Feedback has been deemed a critical component of BST and there are various ways in which feedback can be administered. This study compared the effectiveness and efficiency of providing verbal feedback versus acoustical feedback within a BST package when teaching beginning yoga postures to participants who have never before practiced yoga. No feedback method …

Evaluations Of Health In Sympatric Free-Ranging Saguinus Imperator And Leontocebus Weddelli Using Neopterin, Urinalysis, And Blood Chemistry Analyses, Alexandra J. Sacco

All Master's Theses

This thesis is composed of one journal-ready article and one chapter that includes a preliminary interpretation of data for later publication. In summary, this thesis proposes the use of three different methods of evaluating the health status of New World Monkeys: urinary neopterin measurement, blood chemistry analyses, and urinalysis. Chapter II addresses the question of whether or not the neopterin molecule, a biomarker for cell-mediated immune system activation, is conserved across primate taxa. To do so, we collected urine samples across three New World Monkey (NWM) families including captive Leontopithecus rosalia and Pithecia pithecia, and wild populations of Leontocebus …

Music, Video And Perception: An Investigation Into Shaping Attitudes Toward Fish And Their Natural Habitat, Kayla-Ann Hemmings

All Master's Theses

The current study investigated the influence of music and video on perceptions of fish, willingness to help aquatic conservation efforts, and attitudes about the marine environment. Participants were randomly distributed to one of six groups which varied by presenting information about marine life in a video format or through printed text (i.e., video or pamphlet) and on the background music that played during the presentation of that information (i.e., ominous, uplifting, or no sound). Participants, then, completed several counterbalanced measures, including rating how much six different words (i.e., three positive and three negative) applied to fish, Willingness to Conserve questions …

Ethnoprimatology Of Urban Cebus Yuracus: An Evaluation Of Human-Non-Human Interactions And Local Perceptions In Misahualli, Ecuador, Sofia Castro-Loza

All Master's Theses

Little is known about the group of white-fronted capuchins (Cebus yuracus) coexisting alongside humans in the town of Misahuallí, Tena, Ecuador. This ethnoprimatological study focuses on the human-nonhuman interactions and the perceptions of the local people about the capuchin group. Behavioral interactions were examined using all-occurrence sampling, and the local perceptions of the Misahuallí people were assessed using semi-structured interviews. In total, 2,103 human-capuchin behavioral interactions were recorded. The majority of interactions were positive (55.6%), and 69.6% revolved around food. Overall, the capuchins initiated more negative interactions and in contrast, humans initiated more positive interactions. When interviewed about …

Cold Tolerance, Temperature Mediated Discontinuous Gas Exchange, And Emergence Of The Blue Orchard Mason Bee (Osmia Lignaria), Logan Kral

All Master's Theses

The relationship between low temperatures, emergence and supercooling point of Osmia lignaria were the subject of this study. One hundred sixty-eight bees were subjected to 5 pre-wintering temperature treatments (two constant temperature controls - 22^oC, 14^oC, one of which with and one without a 12h photoperiod, and three 12h:12h thermoperiod treatments – 14:10^oC, 14:5^oC, and 14:0^oC) and were then evaluated in terms of emergence time and post-emergence vigor. An additional 70 bees were tested for metabolic rate and discontinuous gas exchange in response to test temperature conditions. An additional sample …

Modular Synthesis And Hydroalkylation Of Vicinally Functionalized Ketopiperazines: A Solution To The Piperazine Problem, Antonio Moreno

All Master's Theses

The stereocontrolled synthesis of functionalized piperazines is of great interest to pharmaceutical companies owing to their multiple biological activities such as antidepressant, antiparasitic, anticancer and antiretroviral. Current methods towards functionalized piperazines include intramolecular cyclization of appropriately tethered on acyclic precursors as well as α-C–H functionalization of intact piperazine rings. Although effective for the most part, these methods suffer from drawbacks such as the use of expensive catalysts, potentially toxic reagents, limited scope and functional group compatibility. Seeking to side-step some of the aforementioned limitations, we herein describe a step-economical-, cost-effective-, transition metal-free-, and mild approach to highly functionalized piperazines, including …

A Novel Snp Genotyping Technique To Determine Orangutan Relatedness And Genetic Diversity At Camp Leakey In Tanjung Puting, Central Kalimantan, Ruth Ella Linsky

All Master's Theses

Genetic studies of dispersal patterns in wild populations of orangutans (Pongo spp.) have sought to confirm behavioral observations that female orangutans tend to stay near their natal range while males disperse. In order to genotype a previously unsampled wild population of endangered orangutans at Tanjung Puting National Park I developed novel application of a methyl based magnetic capture for enrichment of fecal DNA and commercial human targeted single nucleotide polymorphism (SNP) microarray technology. I confirmed results of this new genotyping technique through standard microsatellite short tandem repeat (STR) micro-capillary genotyping. I estimate genetic diversity and relatedness (r) …

Dna Methylation And Genetic Divergence Associated With An Inducible Defensive Response In Mimulus Guttatus, David Farr

All Master's Theses

Phenotypic plasticity allows many organisms to respond to their environment by changing their phenotype, but the mechanisms to do so are not well understood. Yellow Monkeyflower (formerly Mimulus guttatus; now Erythranthe guttata) is one such organism that can serve as a model to promote our understanding of these mechanisms due to its striking response to insect herbivory. Monkeyflower responds to leaf damage by increasing the number of hair-like glandular trichomes, a putative defensive trait that reduces the magnitude of damage by insects. This plastic response is transgenerationally inherited in a way that is sensitive to genome-wide demethylation when …

Gorilla-Visitor Interface At A Zoo Exhibit: Positioning Effects Of Western Lowland Gorillas (Gorilla Gorilla Gorilla) And Zoo Visitors, Alan Bergman

All Master's Theses

Zoos have missions to provide high-quality care for their animals and an enjoyable and educational experience for visitors. Looking at the animal-visitor interface can allow zoos to evaluate their success in these efforts and to build upon what they have already accomplished. The present study was conducted to investigate the relationship between visitors and gorillas in a zoo environment. The effect of gorilla proximity to visitor viewing areas on visitor attentiveness was examined in indoor and outdoor gorilla exhibits. Visitor experience surveys were collected from visitors exiting the outdoor exhibit. Stepwise multiple regressions revealed group and individual gorilla proximity effects …

A Cognitive Task As Enrichment For Chimpanzees (Pan Troglodytes) In Sanctuary, Federico Rubio

All Master's Theses

Chimpanzees (Pan troglodytes) hold an especially powerful attraction for researchers interested in cognition and how it developed to the degree observed in humans specifically and primates more generally. Chimpanzees are behaviorally complex primates with compelling data supporting their possession of intricate internal lives. The objective of this study was to simultaneously learn more of the cognitive process of inductive reasoning while also assessing the efficacy of a computerized box as a novel form of enrichment to aid in improving the environment of captive chimpanzees. Three social groups at the retired medical research chimpanzee sanctuary Project Chimps were given …

Water And Life. A Cross-Sectional Study On Determinants Of Beverage Consumption And Water Access In One Tribal Community, Christina White

All Master's Theses

Increasingly, poor diet has been shown to be one of the most crucial factors associated with cause of death, even more critical than smoking. Research in the past two decades has consistently linked increased consumption of sugar-sweetened beverages (SSB) to the obesity epidemic contributing to a public health crisis all over the United States. Native Americans, among other minority groups, suffer obesity disproportionately from the rest of the US population, yet they continually fail to be included in research on the subject. Traditional research methods, sparse care coverage on reservations, consolidation of unique tribes into one classification, and failure to …
