A digestive phospholipase a2 in Midguts of worker honey bees, Apis mellifera : significance in lipid nutrition and health
(University of Missouri--Columbia, 2018)
studies on honey bee nutrition and physiology, the enzymes acting in digesting dietary lipids remain understudied. This is an important lacuna because it bears directly on meeting essential dietary fatty acid requirements, which I addressed...
Spring establishment of tall fescue utilizing sunn hemp as a companion crop under rotational grazing management
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 12/01/2024] Tall fescue (Schedonorus arundinaceus (Schreb.) Dumort.) is the predominant perennial cool season grass used for forage in Missouri. It demonstrates a bi-modal seasonal yield distribution with forage production periods...
The evolution and genetic basis of complex traits in Drosophila melanogaster
(University of Missouri--Columbia, 2022)
: constant high nutritional diet (CHA), fluctuating nutritional diet (FA), and deteriorating nutritional diet (DA). These three treatments have been ongoing for over 50 generations. For my experiment, a duplicated set of flies from all replicates...
Pathobiological analysis of developmental dysplasia of the hip and its progression to osteoarthritis
(University of Missouri--Columbia, 2022)
Developmental dysplasia of the hip (DDH) is recognized as one of the leading causes of early-onset hip osteoarthritis and a primary reason for undergoing total hip arthroplasty prior to 50 years of age. Even with an increase ...
Three essays on phosphorus runoff and water quality
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Water pollution caused by nutrients, and the resulting eutrophication, have increased over time. This water pollution is increasingly caused by non-point source pollution, both...
Taxonomic and metagenomic approaches to diet, health, and breeds of ruminants
(University of Missouri--Columbia, 2020)
Ruminant mammals maintain a symbiotic relationship with their gut microbiome, the organisms of which break complex plant matter into metabolites that are absorbed by the host animal for its nutrition. Building on prior work describing the taxonomic...
Quantifying neonicotinoid concentrations in Missouri wetlands, their driving factors, and the potential effects on the reliant avian community
(University of Missouri--Columbia, 2018)
been proposed as indicator taxa as they are reliant on insect food reserves and have recently experienced population declines. Thus, we developed two studies in floodplain wetlands to quantify neonicotinoids in Missouri wetlands and potential effects...
The relationship between high school sport participation and subsequent health behaviors of college young adults
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Researchers have gathered irrefutable evidence substantiating that the increase in childhood obesity rates is primarily due to environmental and lifestyle factors such as (a...
Development of high protein soybean experimental lines with enhanced sulfur amino acid content
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Soybean is one of the most important field crops grown in the United States. Commercial soybeans contain about 36 - 40 [percent] protein and 18 - 20 [percent] oil, by dry weight...
Music Education Professors’ Beliefs Regarding Essential Musical, Academic, and Emotional Skills in Undergraduate Music Education
(University of Missouri--Kansas City, 2017)
Undergraduate music education majors sometimes lack the musical, academic, or
emotional skills needed to successfully complete the degree program. Improvement in
academic and emotional skills has been shown to have a ...
Prairie stream ecology : temporal and spatial patterns of macroinvertebrates
(University of Missouri--Columbia, 2018)
patches to enable recolonization of streams after disturbance. Leptophlebia konza Burian was thought to be restricted to its type locality of Konza Prairie, Kansas; however, a population was discovered at Hi Lonesome Prairie in Missouri during an extensive...
The influence of body mass and body composition on bone functional adaptation
(University of Missouri--Columbia, 2023)
The proposed dissertation follows a three article format. The articles are distinct, but each pertains to the same subject of research. The first article applies structural equation modeling to factors influencing bone ...
In vitro digestion and beta-carotene delivery of emulsion stabilized by heated WPI and pectin mixture
(University of Missouri--Columbia, 2018)
and extensive coalescence. These changes have been found to decrease bioaccessibility of beta carotene. The presence of pectin could lead to oil droplet flocculation with much lower extent of coalescence which resulted in decreased beta-carotene release and thus...
The role of serum-glucocorticoid-regulated kinase (SGK1) in arterial reactivity
(University of Missouri--Columbia, 2023)
genes including the SGK1, EnNaC, and Na+/K+ -ATPase. Preliminary studies from our group observed a change in EnNaC current in SGK1 global knockout mice with aldosterone (10nM) treatment for 24 hours. We thus hypothesized that altered expression of SGK1...
Nitrogen management strategies to improve corn growth and reduce soil greenhouse gas emissions from claypan soils
(University of Missouri--Columbia, 2018)
. The objective of this study was to determine the effects of urea fertilizer placement with and without the addition of a nitrification inhibitor (NI) on corn yield, N use efficiency (NUE), and cumulative soil N[2]O emissions on a Northeastern Missouri claypan...
Molecular approaches to improve soybean plant architecture and seed composition
(University of Missouri--Columbia, 2021)
Soybean is an important agronomic crop which has been widely used as a vegetable oil as well as a source of protein for animals and humans. Among various desired traits for genetic improvement to improve the value of ...
