Construction Of A Reference Allelic Ladder For An Odocoileus Str Multiplex, Jolene Strand

Master's Theses

Odocoileus is a genus of Cervidae (deer) consisting of white-tailed deer (Odocoileus virginianus, Zimmerman, 1780), mule deer (Odocoileus hemionus, Rafinesque, 1817) and blacktailed deer (Odocoileus hemionus hemionus, Rafinesque, 1817). Hunting Odocoileus is only legal with proper permits according to laws that dictate when, where, how, and what can be hunted. Anything outside the legal limits is considered to be poaching. A useful tool for investigating poaching cases is Short Tandem Repeat (STR) DNA analysis. This is commonly used in human forensic casework to link DNA evidence found at crime scenes to either victims or suspects. In poaching cases, it can …

Effectiveness Of Windrow Composting Methodology In Killing A Thermo-Tolerant Species Of Salmonella During Mortality Composting, Spencer Gabriel Myers

Master's Theses

In a large agricultural operation, such as the one at Cal Poly San Luis Obispo, disposal of deceased animals is an immense issue. The cost of transporting and rendering every dead animal is inhibitory to the general function of the agricultural operations and their thin budget. Therefore, we propose that composting mortalities could be an economical alternative. Composting is a recognized method for taking animal waste products along with carbon waste and turning it into a pathogen-free, nutrient-rich topsoil. Carcass composting is in fact performed in other countries and states to varying degrees of success. However, the California EPA limits …

Suitability Of Cultivated Forms Of Native Shrubs To Support Pollinators, Jacob Gordon Ricker

Master's Theses

There is increased interest in native plants for landscaping to support pollinators. The majority of native plants sold by nurseries are cultivars. Some consumer and conservation groups question the suitability of native cultivars to support pollinators. This work evaluated insect pollinator visitation for six native shrub species, and one or more cultivars of each species. The following species were installed in a full sun field behind the University of Connecticut Floriculture Greenhouse Facility in a randomized complete block design with three replicates: Aronia melanocarpa, A. melanocarpa ‘UCONNAM012’ Ground Hog®, A. melanocarpa ‘UCONNAM165’ Low Scape Mound®, Clethra alnifolia, C. …

Synthesis And Evaluation Of Novel Silica Hydride-Based Stationary Phases For Bioanalytical Applications, Seiichiro Watanabe

Master's Theses

Most HPLC columns are packed with silanol (Si-OH)-rich type-B silica that often participates in undesired electrostatic interactions with sample solutes and produces a poor analyte peak shape. These silanols are also known to facilitate the surface hydration required for HILIC mode to retain polar analytes. However, the hydrated surface composition can easily fluctuate, which results in poor reproducibility and requires a lengthy equilibration step. In this study, four novel stationary phases have been developed by using the TYPE-C™ silica material, in which up to 95% of the surface silanols have been replaced with Si-H group. One of the advantages of …

Seasonal Diet Variation In Thirteen-Lined Ground Squirrel (Ictidomys Tridecemlineatus) In Southernwestern Michigan, Austin Menzmer

Master's Theses

Thirteen-lined ground squirrels (Ictidomys tridecemlineatus) are omnivorous ground squirrels that range from Texas to Alberta and from Michigan to Utah. The amount and type of both animal and plant matter in their diet may vary both geographically and seasonally. The present study was motivated by prior work, based on δ13C analysis of incisor enamel of thirteen-lined ground squirrels from a colony in southwestern Michigan, suggesting that these animals underwent a pronounced, late-season shift in diet from predominantly C3 to C4 plants. However, this inferred dietary shift was not directly demonstrated. Here, I tracked diet of thirteen-lined ground squirrels in southwestern …

A Biblical Overview Of The Concept Of Fruit With An Emphasis On The "Fruit Of The Spirit" In Galatians 5, Timothy Selinger

Master's Theses

Problem

The topic of the Holy Spirit and especially the meaning of "being filled with the Spirit" is a relevant topic. Generally, it is thought to be related to miracles, healings, and explosive church growth among Adventists or to speaking in tongues and other manifestations, especially among Charismatic Christians. Few identify the fullness of the Spirit with holiness of character. In Paul, the presence of the Spirit in the life of the believer results in the presence of the "fruit of the Spirit" (Gal 5:22). Just like an apple tree produces apples, a person filled with the Spirit will produce …

Mllt3 Regulates Expression Of Genes Critical To Liver Metabolic Homeostasis, Jonathan Richard Dixit

Master's Theses

Hepatic steatosis (fatty liver) is increasingly prevalent in the US, and is characterized by triglyceride accumulation within hepatocytes. This is a direct result of an imbalance between lipid import, export, de novo lipogenesis, and beta oxidation. Hepatic steatosis can also progress to nonalcoholic steatohepatitis (NASH) which is characterized by increased hepatocyte damage, inflammation, and fibrosis. Further progression can lead to liver failure or hepatocellular carcinoma, requiring liver transplant or causing death. Our lab recently created Mllt3 conditional whole body knockout mice. These mice developed hepatic steatosis and NASH following Mllt3 deletion. MLLT3 is a master gene regulator that is part …

Ecological Stoichiometry: What Role Does It Play In The Competition And Spatial Distribution Patterns Of Aedes Albopictus And Aedes Aegypti?, James Deerman

Master's Theses

Ecological stoichiometry is the balance of chemical substances within animal bodies through interactions and processes within their ecosystem. Though relatively underexplored, it provides a wealth of information linking interactions across different levels of organization. Detritus is the base of the food web within the small aquatic ecosystems occupied by the mosquitoes Aedes albopictus and Aedes aegypti. Nutrient content of detritus varies, but it can have a negative effect on mosquito growth and survival if nutrient thresholds are not met. I investigated nutrient environments and species abundance in cemetery vases in New Orleans, LA to assess detrital heterogeneity and its …

Freshwater Invertebrate Assimilation Nutrients From Detrital Biofilms Under Light And Phosphorus Manipulation, Taylor Price

Master's Theses

Anthropogenic influences are increasing algal biomass and activity within aquatic ecosystems, stimulating debate regarding interactions between “green” and “brown” food webs. Specifically, in forested streams, the removal of forest canopy or riparian zones increases light exposure and nutrient fluxes to streams affecting primary productivity and carbon (C) flows across aquatic food webs. Further understanding the synergistic effects of light and nutrients on detrital biofilms may explain how aquatic detritivores respond to anthropogenic change. The objective of this study was to employ C and phosphorus (P) isotopic radiolabels to understand how microbial biofilm constituents (i.e heterotroph and autotroph) contribute C and …

Investigating Possible Scurvy In The Postclassic Maya Of Tipu, Emmalea Gomberg

Master's Theses

Although residing in a tropical environment, numerous researchers have posited the possibility of scurvy in the Maya in recent years. The historic population of Tipu in western Belize dating to AD 1541-1638 is one of the largest and best preserved Maya series, and was therefore evaluated for possible presence of scurvy since the diet appears typical of the pre-contact Petén populations. The temporal bones and greater wings of the sphenoid were analyzed for scorbutic activity in 143 individuals, along with periodontal disease and antemortem tooth loss to determine if there was a co-occurrence with scurvy.

Overall, 27% of the sample …

Pseudomonas/Brachypodium As A Model System For Studying Rhizosphere Plant Microbe Interactions Under Water Stress, Janiece Mcwilliams

Master's Theses

In contrast to well-studied mechanisms of drought tolerance in plants, the interactions between plants and their microbiome during water stress are still poorly understood. This missing knowledge is crucial for the exploitation of beneficial microbial communities to improve the sustainability of agriculture under changing climatic conditions. The research described here bridged this gap by focusing on the molecular interactions between beneficial rhizobacterium Pseudomonas synxantha 2-79 and annual grass Brachypodium distachyon Bd21. 2-79 exemplifies a group of rhizobacteria associated with dryland wheat, while B. distachyon originates from the Middle East and has emerged as a model for valuable biomass, food, forage, …

Cleaver: Classification Of Everyday Activities Via Ensemble Recognizers, Samantha Hsu

Master's Theses

Physical activity can have immediate and long-term benefits on health and reduce the risk for chronic diseases. Valid measures of physical activity are needed in order to improve our understanding of the exact relationship between physical activity and health. Activity monitors have become a standard for measuring physical activity; accelerometers in particular are widely used in research and consumer products because they are objective, inexpensive, and practical. Previous studies have experimented with different monitor placements and classification methods. However, the majority of these methods were developed using data collected in controlled, laboratory-based settings, which is not reliably representative of real …

The goal of this study was to understand the relationship between food neophobia and bitterness in consumer liking. Fruit and vegetable consumption is necessary for elementary school children to build healthy habits. Free and reduced lunch programs (FRL) in schools provide nutritional opportunities to students. Bitterness sensitivity and food neophobia were examined as separate drivers of liking in acceptance testing (n=161, ages 6-12) from two local elementary schools (high and low %FRL). The food neophobia scale and the fruit and vegetable neophobia instrument (FNVI) were used to determine food neophobia. FNVI scores distinguished consumers in hierarchical cluster analysis of overall …

Comparative Transcriptomic Analysis Of Developmental Stages In Isolated Mammary Epithelial Cells, Nicole K. Einfalt

Master's Theses

The mammary gland is an organ common to all mammals; it is of value for neonatal nourishment, human nutrition through dairy consumption, and is a source of pathology in humans through the development of breast cancer. While transcriptomic analyses have been applied to cultured mammary epithelial cells (MEC) and to whole gland samples, few have studied purified MEC isolated directly from the gland in vivo. To identify the differentially expressed genes influencing MEC development during pregnancy and the differences between the nulliparous and primiparous quiescent states, primary MEC were isolated from virgin, pregnant, and primiparous quiescent sibling mice. Computational …

The Effect Of Spill Contaminants On Marine Biofilms And Microbially-Induced Corrosion Of Carbon Steel, Rachel Mugge

Master's Theses

There are over 2,000 known historic shipwrecks located in the northern Gulf of Mexico which are ecological and cultural resources that support the diversity of life found in the deep-sea when they become artificial reefs. Spilled crude oil and chemical dispersant from the Deepwater Horizon (DWH) spill may have impacted the preservation of deep-sea historic shipwrecks and their microbiomes if they are located in areas where oil and dispersant were deposited on the seafloor. Oil potentially accelerates corrosion of metal through a biologically-mediated process called microbially-induced corrosion (MIC). Introduction of spill contaminants may accelerate MIC on shipwreck hulls, which may …

Biochemical Study Of A Chymotrypsin-Like Serine Protease, Aachymo, From The Female Aedes Aegypti Mosquito, Olive Escalicas Burata

Master's Theses

The Aedes aegypti female mosquito is a dominant vector of four bloodborne viruses: dengue, chikungunya, yellow fever, and Zika. Defenses against viral infection are reliant on human competence to limit interactions with the vector or through abatement using

methods that are either too expensive or ecologically invasive upon other species. An alternative vector control approach focuses specifically on blood meal protein digestion, which is a required process to fuel the gonotrophic cycle. Reduction of eggs laid can be

observed by inhibiting midgut serine proteases that are afterward released in the midgut in the presence of a blood meal. Trypsin-like serine …
