Imidacloprid sorption and transport in cropland, grass buffer and riparian buffer soils
(University of Missouri--Columbia, 2016)
sorption and column leaching experiments were performed using soils collected from cropland (crop), grass vegetative buffer strips (VBS), and riparian VBS. Single-point, solid-to-solution partition coefficients (Kd) were determined by reacting soil...
Glyphosate resistance : pollen movement within a common ragweed (Ambrosia artemisiifolia L.) population and herbicide release from common waterhemp (Amaranthus rudis sauer) plants
(University of Missouri--Columbia, 2011)
Common ragweed and Common waterhemp are native, summer annual weeds distributed widely throughout the United States. Both weed species have developed resistance to the broad-spectrum herbicide glyphosate. Research was conducted to determine...
Fire risk assessment of the western portion of the central hardwoods forest region
(University of Missouri--Columbia, 2008)
This study examined how fire risk, a combination of fuels conditions and fire probabilities, varied across a large portion of Missouri, Illinois, and Indiana. Case studies were conducted to evaluate the fuel loading variability in Missouri Ozark...
Delineation of critical management areas at plot, field, and watershed scales for claypan soils
(University of Missouri--Columbia, 2010)
and water quality and given rise to non-point source pollutants. The claypan soil region of Missouri has a high runoff potential that increases the possibility of transport of non-point source pollutants to downstream sites. The Agricultural Policy...
Analysis of landscape characteristics surrounding deer vehicle accidents in St. Louis County, Missouri
(University of Missouri--Columbia, 2008)
). This study quantifies landscape factors that contribute to deer vehicle accidents in St. Louis County, Missouri, and provides a predictive model of areas in which DVA's would likely be found. Geographic Information Systems (GIS) was used to plot deer...
Missouri crop performance, 2004 : Corn
(2004)
Compares hybrids and includes experimental procedures, seed corn characteristics and seed corn company addresses.
The kinetics of non-catalyzed supercritical water reforming of ethanol
(University of Missouri--Columbia, 2008)
Agriculturally produced ethanol, a renewable resource, may be reformed noncatalytically into hydrogen by a novel process utilizing supercritical water, which acts synergistically both as a solvent and as a reactant. By utilizing supercritical water...
Pediatric Lead Poisoning and The Built Environment in Kansas City, Missouri 2000-2013
(2021)
This study examines relationships between pediatric lead poisoning and the built environment. Focusing on Kansas City, Missouri between the years 2000 and 2013 this dissertation informs policy options and identifies under-explored lines of inquiry...
Evaluation of the Private Forestland Ownership Paracelization and its effects on the forest landscape in the southeastern Missouri Ozarks
(University of Missouri--Columbia, 2005)
This study investigates the impacts of the forestland ownership parcelization on species composition, age structure and spatial pattern of the forest landscape. First, a computer model was developed to create ownership ...
Resource extraction, resistance, and religion in Nicaragua
(University of Missouri--Columbia, 2019)
My dissertation examines the causes of protest over resource extraction in Nicaragua, and underlines the role of religion as a catalyst for sustained and successful challenges against resource extraction. With few exceptions, existing research has...
Characterization of diverse soybean genotypes for phosphorus uptake and use efficiency
(University of Missouri--Columbia, 2021)
was aimed at identifying and characterizing soybean genotypes which contrast in their ability to take up P and in their PUE. Results from pot and field experiments with diverse soybean genotypes, including SoyNAM parents, obsolete cultivars, commercial...
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...
Multi-scale factors influencing detection, site occupancy and resource use by foraging bats in the Ozark Highlands of Missouri
(University of Missouri--Columbia, 2007)
Conservation of bat populations requires understanding the associations between bats and their use of resources. We used maximum likelihood to estimate probability of site occupancy using acoustic data for ten species of ...
Cover crop effects on soil moisture dynamics & thermal properties
(University of Missouri--Columbia, 2021)
properties of a corn (Zea mays L.) cropping system. The study was conducted at the Elsberry Plant Material Center - USDA, Missouri, USA, with 1) no-till cover crop (NC), 2) conventional till no cover crop (CN), and 3) no-till no cover crop (NN) treatments. A...
Seasonality and elevational migration in an Andean bird community
(University of Missouri--Columbia, 2010)
Life history strategies of many birds in the Neotropics remain poorly known. In particular, details on the seasonal movements of individuals and populations within the Neotropics remain largely unknown, including short-distance ...
Effects of Selected Contaminants on the Physical, Chemical, and Geotechnical Properties of Aquifer Solid
(2014)
The primary objective of this study was to investigate the potential effects of hydrocarbons on the geotechnical properties of sand. A series of laboratory experiments were carried out to ascertain the influence of some common and widespread organic...
Genetic mapping of soybean cyst nematode resistance and evaluation of resistant germplasm in soybean and pennycress
(University of Missouri--Columbia, 2022)
pennycress germplasm. We identified one common susceptible germplasm, eight resistant germplasm against HG type 1.2.5.7, and four resistant germplasm against HG type 7. The resistant pennycress germplasm identified here opens a new research avenue...
