Exploring elementary student energy literacy outcomes in the outdoor classroom : a comparative study
(University of Missouri--Columbia, 2020)
Environmental issues such as global warming, air and water pollution, and excessive consumption of fossil fuels are the challenging problems that endanger the future of our planet and, consequently, humankind. These problems ...
Endocrine associations with beef carcass quality and yield
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Serum concentrations of insulin, insulin-like growth factor I (IGF-I) and leptin were investigated relative to their association to beef carcass quality and yield grades...
Behavioral responses of drosophila suzukii (diptera: drosophilidae) to olfactory and visual cues
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Selected fruit and leaf volatiles were assessed to determine their attractiveness to Drosophila suzukii Matsumura (Diptera: Drosophilidae). Two- and four-choice assays were...
Fire effects and litter accumulation dynamics in a montane longleaf pine ecosystem
(University of Missouri--Columbia, 2009)
A common obstacle for public land managers developing fire management plans in the eastern and southern United States is the lack of quantitative information on historic fire regimes and the effects that varying fine fuel ...
The impacts of partner abundance on benefits from facultative pollination mutualism
(University of Missouri--Columbia, 2010)
, Trifolium dasyphyllum and T. parryi, that vary in specialization on a shared bumblebee pollinator, Bombus balteatus. I examined a) foraging choices of queen B. balteatus among the clovers and explanatory mechanisms behind observed foraging biases, b) how...
Accrual persistence and accrual anomaly
(University of Missouri--Columbia, 2007)
The first essay, "Inter-temporal accrual persistence and accrual anomaly" investigates whether accrual persistence and accrual anomaly vary with the state of economy. Prior accounting research argues that diminishing ...
An ecological study of American Ginseng (Panax quinquefolius L.) in the Missouri Ozark Highlands: effects of herbivory and harvest, ecological characterization and wild simulated cultivation
(University of Missouri--Columbia, 2006)
Matrix population analysis was used to analyze eight years of demographic data from six American ginseng (Panax quinquefolius L.) populations in east-central Missouri to examine effects of herbivory by white-tailed deer (Odocoileus virginianus Zimm...
Politics and ideology in the Kingdom of Callaway
(University of Missouri--Columbia., 1963)
"This is a study of politics in the town of Fulton, the county of Callaway, in the state of Missouri. It is a study which, from one standpoint, is limited in its scope and focus. No attempt is made to describe and to delineate in great detail...
Synthesis, Characterization and Device Studies of Conjugated Foldamers
(University of Missouri--Kansas City, 2017)
Conjugated polymers have found a wide range of electronic applications in last few
decades due to their superior combination of optoelectronic, mechanical properties, and
solution processability. In the past few years, ...
Genomics of seasonal hair shedding and ecoregion-specific growth to identify environmentally-adapted beef cattle
(University of Missouri--Columbia, 2020)
Recently, interest has increased in augmenting current national scale cattle evaluations with precision genetic predictions tailored to specific environmental conditions. Some efforts to develop environmentally-aware ...
Nutrients, chlorophyll and bacterial fecal indicators in coves and open water areas of Lake of the Ozarks, Missouri
(University of Missouri--Columbia, 2009)
Urban development and use of septic tanks in porous soils of Lake of the Ozarks poses a threat to public health via leaching into drinking wells and coves used for swimming. During 2 summers, phosphorus (TP), nitrogen (TN), ...
Multi-scale investigations of gray treefrong movements: patterns of migration, dispersal, and gene flow
(University of Missouri--Columbia, 2005)
determining microhabitat use. Further, I have demonstrated the effects of matrix composition on the frequency of inter-pond movements and elucidated historical patterns of gene flow across central Missouri. My data indicate that migration through terrestrial...
Influence of various wetting agents on water status in USGA greens as determined by their physical properties
(University of Missouri--Columbia, 2021)
Soil hydrophobicity is an increasing issue in sandy soils, affecting agricultural land and golf courses. This phenomenon causes water repellency and bypassing of hydrophobic root zones, limiting water accessibility. Due to golf course putting greens...
Site preparation for longleaf pine restoration on hydric sites : stand development and ground flora responses 15 years after planting
(University of Missouri--Columbia, 2019)
Longleaf pine (Pinus palustris Mill.) restoration is an important land management goal throughout the Southeast. On hydric sites within the Atlantic Coastal Plain, restoration may involve site preparation prior to planting ...
Value addition to acid whey from Greek yogurt processing with millets (kodo and proso) for development of nutritious food products
(University of Missouri--Columbia, 2022)
The disconnect between massive demand and abundant supply of food has resulted in millions of people suffering from hunger and billion metric tons of food being wasted. Circular food economy could be a solution to the ...
Effects of continous administration of low-dose of Escherichia coli lipopolysaccharide in chicks and poults fed non toxic doses of aflatoxin B1 and T-2 toxin
(University of Missouri--Columbia, 2005)
Six studies (three with broilers and three with turkeys) were conducted to determine if E. coli lipopolysaccharide (LPS) would enhance the effects of aflatoxin B1 (AFB1) and the T-2 toxin (T-2) in chicks and poults fed ...
Uterine regulation of preimplantation embryo development in fertility-classified heifers
(University of Missouri--Columbia, 2018)
, serial embryo transfer (3-4 rounds) was used to classify heifers based on pregnancy success on day 28 as high fertile (HF; 100%), subfertile (SF; 25%), or infertile (IF; 0%). Next, a series of experiments were conducted using the fertility...
