Identifying Genetic Factors Influencing Sperm Mobility Phenotype In Chicken Using Genome Wide Association Studies, Primordial Germ Cell Transplantation, And Rnaseq., Sohita Ojha
Graduate Theses and Dissertations
Sperm mobility is a major determinant of male fertility in chicken. In spite of low heritability of reproductive traits, sperm mobility has high heritability index which suggests presence of quantitative trait loci (QTLs) governing the trait. Our research focused on three objectives: i) to identify the QTLs affecting low mobility phenotype in chicken, ii) to understand the impact of Sertoli-cells and germ cells interactions in influencing the mobility phenotype and iii) to identify the genes and gene networks differentially expressed in male and female PGCs. To detect the QTLs, genome wide association studies (GWAS) was conducted which revealed the presence …
Effects Of Pre-Chiller Temperature On The Microbial Ecology Of Whole Bird Carcass Rinses, Rachael Elizabeth Blevins
Effects Of Pre-Chiller Temperature On The Microbial Ecology Of Whole Bird Carcass Rinses, Rachael Elizabeth Blevins
Graduate Theses and Dissertations
Upon entering a poultry processing facility, birds are already contaminated with a variety of microorganisms. It is the responsibility of the processor to reduce these numbers to deliver a wholesome product to customers. This is not an easy task as there are ample opportunities for further microbial contamination. Some of these opportunities are obvious. For example, any areas where contaminants could be washed off one bird and onto another are always an area for concern, i.e. the scalder or the chiller. There are numerous opportunities for contamination that are not so obvious. These incidents of contamination are not necessarily due …

Chemistry & Biochemistry Dissertations - Archive
Post-translational modification of proteins plays a significant role in the regulation of cellular processes. During the translation, process proteins undergo different modifications, which are known as post-translational modifications (PTMs). Due to their low abundances, PTM analysis presents several challenges; therefore, efficient and sensitive PTM detection methods are required. Arginine is an essential amino acid in a cell, which undergoes several kinds of PTMs. Finding these functional arginine residues in a protein is a challenging task. The task was successfully addressed, and the findings are not only reported herein, but an assessment was recently reported covering the new chemical labeling methods …

Distributions Of Krill And Antarctic Silverfish And Correlations With Environmental Variables In The Western Ross Sea, Antarctica, L. Brynn Davis, Eileen E. Hofmann, John M. Klinck, Andrea Piñones, Michael S. Dinniman
CCPO Publications
Antarctic krill Euphausia superba, crystal krill E. crystallorophias, and Antarctic silverfish Pleuragramma antarctica are key mid-trophic level species in the Ross Sea, connecting primary production to the upper trophic levels. Distributions of these species were constructed from observations made in the western Ross Sea from 1988 to 2004. Distributions of environmental conditions were obtained from a 5-km resolution circulation model (temperature, mixed layer depth, surface speed) and satellite-derived observations (chlorophyll, sea ice cover). A hierarchy of statistical methods determined correlations and relationships between species and environmental conditions. Each species occupies a localized habitat defined by different environmental characteristics. …
Horticulture For Pollinator Conservation, Carter M. Westerhold
Horticulture For Pollinator Conservation, Carter M. Westerhold
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Pollinators worldwide are declining. Consequently, the agricultural and ecological services these insects provide are in danger of being lost. Land use intensification, via urbanization, has greatly influenced this decline in pollinators. Luckily, through targeted horticultural practices, stable populations of pollinators can be sustained within urban areas. The horticultural practices of planting diverse floral resources and managing pollinator habitat in urban areas can sustain these populations. Two studies were conducted with the intent to identify horticultural knowledge gaps that could be reduced to aid in pollinator conservation efforts. First, a study to compare Nebraska native and non-native ornamental plants was conducted. …

Flushing Responses Of Golden Eagles (Aquila Chrysaetos) In Response To Recreation, Robert J. Spaul, Julie A. Heath
Biology Faculty Publications and Presentations
Disturbance because of human activity, including recreation on wildlands, can affect bird behavior which in turn can reduce breeding success, an important consideration for species of management concern. We observed Golden Eagles (Aquila chysaetos) during the breeding season to determine whether the probability of flushing was affected by the type of recreationist, distance to encounter, eagle nest attendance, or date. We monitored eagles in 23 nesting territories from distant (600-1,200 m) observation points and recorded recreation activity within 1,200 m of eagles in the Owyhee Front of southwestern Idaho. In most (86%, n = 270) encounters, eagles did …

Preschoolers And Pandas Making Friends: A Journey About Healing From Brain Injury, Barbara Anne Doucette
Museum Studies Projects
Preschoolers that have obtained Non-Accidental Injury (NAI) from familial child abuse are in need of having a unique place for neurorehabilitation in correlation with traditional therapies. My thesis project suggests adding an exhibit annex to an existing giant panda exhibit that will give preschoolers an opportunity to help develop new neuropathways when exposed to mediation and creative activities. Meditation and creative activities are being examined by neuroscientists as an aid in neuroplasticity after brain injury. This thesis reviews the neurotypical preschooler’s milestones and the playful means by which they are achieved. Conjoining the contemporary museums’ and zoological gardens’ outreach to …

Strengthening The Teacher Toolkit: Effective Autism Inclusion Methods, Roxanne Guel
Capstone Projects and Master's Theses
The focus of this Capstone Project is on Autism inclusion methods. This is an important issue for teachers because they are often not given the tools and resources to effectively include their students with Autism Spectrum Disorders into a general education classroom. It is argued that some of the most effective methods include peer-mediated instruction, antecedent procedures, and school-wide organizational change. Considerations of the issue, should include the perspectives of both Special Education and General Education teachers. Three themes/action options emerged from an analysis of the data and were explored as ways to address the issue presented. Antecedent procedures are …

Slipping Through The Cracks: A Look Into Special Education Referrals, Courtney Musselman
Capstone Projects and Master's Theses
Special Education is offered in many schools today and more and more students are being referred to this type of education. For this capstone project three local special education teachers were interviewed about the referral process and what could be done to improve it. This is an important issue because many students are slipping through the cracks when it comes to be identified and others are being overly identified. The referral process is important because it provides students with an equal opportunity for education. Findings from the interviews and information from a relevant literature review were used to develop an …

Sanders-Brown Center on Aging Faculty Publications
People with Down syndrome (DS) are at high risk for developing Alzheimer disease (AD) with age. Typically, by age 40 years, most people with DS have sufficient neuropathology for an AD diagnosis. Interestingly, atherosclerosis and hypertension are atypical in DS with age, suggesting the lack of these vascular risk factors may be associated with reduced cerebrovascular pathology. However, because the extra copy of APP leads to increased beta-amyloid peptide (Aβ) accumulation in DS, we hypothesized that there would be more extensive and widespread cerebral amyloid angiopathy (CAA) with age in DS relative to sporadic AD. To test this hypothesis CAA, …

The decision to become an international student is a choice that is as challenging as it is rewarding, and is one that I am familiar with from both a professional and personal standpoint. Per a recent Open Doors’ account, 1,043,839 students from around the world have made the decision to study in the United States in 2016. These individuals make up 9% of New York State’s student population, and 10.1% of the State University of New York system (SUNY, 2016). Currently SUNY Oneonta is host to 56 of these international students, whom I was excited to work with through my …
Control Surfaces Of Aquatic Vertebrates: Active And Passive Design And Function, Frank E. Fish, George V. Lauder
Control Surfaces Of Aquatic Vertebrates: Active And Passive Design And Function, Frank E. Fish, George V. Lauder
Biology Faculty Publications
Aquatic vertebrates display a variety of control surfaces that are used for propulsion, stabilization, trim and maneuvering. Control surfaces include paired and median fins in fishes, and flippers and flukes in secondarily aquatic tetrapods. These structures initially evolved from embryonic fin folds in fishes and have been modified into complex control surfaces in derived aquatic tetrapods. Control surfaces function both actively and passively to produce torque about the center of mass by the generation of either lift or drag, or both, and thus produce vector forces to effect rectilinear locomotion, trim control and maneuvers. In addition to fins and flippers, …

Comparing Two Alternate Assessments: Dynamic Learning Maps And Multi-State Alternate Assessment, Dana N. Sir
Seton Hall University Dissertations and Theses (ETDs)
In 2001 under No Child Left Behind, states were required to create an alternate assessment for students with significant cognitive disabilities using alternate achievement standards. In 2003, all states had created an alternate assessment. All fifty states independently developed, implemented, and revised their alternate assessments. By 2014, Dynamic Learning Map (DLM) and Multi-State Alternate Assessments (MSAA) (formerly National Center and State Collaborative)––two alternate assessments developed through consortiums consisting of state departments, universities, and organizations using federal funding––were created. At the time of this study, the DLM and MSAA were used by approximately 49% of states for their alternate assessment. This …

Individual, Ecological, And Anthropogenic Influences On Activity Budgets Of Long-Finned Pilot Whales, Saana Isojunno, D. Sadykova, Stacy L. Deruiter, C. Cure
University Faculty Publications and Creative Works
Time allocation to different activities and habitats enables individuals to modulate their perceived risks and access to resources and can reveal important trade-offs between fitness-enhancing activities (e.g., feeding vs. social behavior). Species with long reproductive cycles and high parental investment, such as marine mammals, rely on such behavioral plasticity to cope with rapid environmental change, including anthropogenic stressors. We quantified activity budgets of free-ranging long-finned pilot whales in order to assess individual time trade-offs between foraging and other behaviors in different individual and ecological contexts, and during experimental sound exposures. The experiments included 1-2 and 6-7 kHz naval sonar exposures …

Comparing The Effectiveness Of Alternative And Prescription Antibiotics Against Gram-Positive Bacteria, Rachel Jenkins, Roan Dickenson, Sam Turnbull, Marcela Torres
Senior Theses
The rapid emergence of antibiotic-resistant bacteria is a global public health concern that threatens the efficacy of antibiotic drugs. We found that natural remedies, specifically coconut oil, honey and cinnamon essential oil, have the potential to be used as a clinical alternative to treat antibiotic-resistant infections. In this experiment, we performed a disk diffusion test and measured the area of inhibition of each treatment to compare the effectiveness of natural and prescription antibiotics. Cinnamon essential oil showed significantly greater antibiotic activity compared to a prescription treatment, amoxicillin. With bacterial resistance continuously expanding, more work needs to be done to determine …

Assessment And Attitudes: Biodiversity In Urban Landscapes Of North Central Texas, Gray Harrison Kerry A.
Landscape Architecture Masters & Design Theses - Archive
North Central Texas is expected to undergo increased population growth and density inside and outside of current municipal boundaries. As development increases to meet the needs of the growing population, the landscape is transformed, which results in the loss or homogenization of species (McKinney, 2006; Vitousek, Mooney, Lubchenco, & Melillo, 1997). This study examined how landscape architects can quickly assess biodiversity on a project site before and after construction without specialized knowledge or skills. Three methods were used to collect data for this study: interviews, a DNA assessment of soil fungi, and a rapid biological assessment (BioBlitz). Two groups were …
