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...
Environmental drivers of Northern bobwhite fall and winter survival and resource selection in Southwest Missouri
(University of Missouri--Columbia, 2020)
, while there was a negative effect of grass on winter resource selection. Woody cover was an important component of vegetation contributing to fall and winter survival and resource selection of bobwhite in Missouri. More specifically, proximity to shrubs...
Effects of low crude protein diets with amino acid supplementation on broiler performance in the starter period
(University of Missouri--Columbia, 2009)
A series of experiments were conducted to examine the effects of feeding low crude protein (CP) corn and soybean meal diets with crystalline amino acid supplementation to broilers from 0-3 weeks of age. It was hypothesized that these diets would...
Investigation of transportation innovations for food delivery and truck platoons
(University of Missouri--Columbia, 2022)
Studies find that low-income areas are underserved by food retailers and have less access to healthy food, contributing to health disparities. A section of this thesis examines micromobility, drones, and ridesharing that ...
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...
Agro-pastoral Landuse Transformation: Implications and Perspectives in the Northwest Region of Cameroon
(2015-08-11)
This dissertation centers on the human-environmental problem of agro-pastoral
landuse transformation in Northwest Cameroon, identifying population pressure, climate
change, environmental degradation, land grabbing, change ...
Bed degradation of the lower Missouri River
(2013-06-04)
The phenomenon of bed degradation can be due to a multiplicity of causes, but ultimately reflects a change in either the sediment input or sediment transport capacity of a system. Causes for the accelerated rate of degradation of the lower Missouri...
Integrating cover crops into crop rotations in upstate Missouri
(University of Missouri--Columbia, 2018)
"There is an increasing emphasis on management strategies such as reduced tillage, use of cover crops, and implementation of conservation practices (i.e. terraces, no-till, and cropping systems) in Missouri cropping systems. By combining best...
Methods for high-resolution soil-landscape modeling in midwest upland landscapes
(University of Missouri--Columbia, 2008)
. These methods were tested in the upland landscapes of northern Missouri. Sensors, especially DRS, successfully estimated profile clay and organic carbon. Peak functions were valuable for modeling profile clay content and covariates of clay. Coherent depth...
Playa wetland plant and soil response to predicted climate and land use change in the southern Great Plains
(University of Missouri--Columbia, 2019)
, and microbial community and structure; (2) compare ecosystem response to changing climatic conditions between Northern (Nebraska) and Southern (Texas) playa soils; and (3) assess effectsof increased agricultural nitrogen inputs on playa plant communities...
River restoration in the upper Mississippi River Basin
(University of Missouri--Columbia, 2006)
River restoration has become an important management choice to address causes and effects of surface water impairment and river modification in the Upper Mississippi River Basin (UMRB). I report information on individual ...
The Impact of Climate Variability and Land Cover Change on Groundwater Resources in The Niger River Basin
(2021)
from 2001-2013, the precipitation increased during the dry season by about 3%, but no significant change was observed during the wet season. The change in the LULC increased substantially in the areas dominated by agriculture, forests, and shrubs...
Effects of amending a gravel based growing medium with calcined clay on medium physical properties and growth of Gymnocladus dioicus seedlings
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Missouri Gravel Bed (MGB) is a system that uses pea gravel with 10% sand (v/v) as a root growth medium, allowing bare root plants to be removed from the gravel and planted...
Horticultural crop response to synthetic auxins
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Rising adoption of dicamba-tolerant soybeans increases the potential exposure of grapes to dicamba, where off-target injury may occur via particle or vapor drift. In 2017...
The sublethal effects of methoxyfenozide on the field orientation and courtship behavior of Cydia pomonella (Linnaeus) (Lepidoptera: tortricidae)
(University of Missouri--Columbia, 2008)
The sublethal effects of ecdysone agonist methoxyfenozide on the mating behavior and field orientation of codling moth, Cydia pomonella (Linnaeus), was examined. Five different lure types were placed in the upper canopy ...
Analysis of twenty-five years of heavy rainfall events in the Texas Hill Country
(University of Missouri--Columbia, 2008)
climate stations in the region; the period examined for this study was 1982-2006. Days with measurable precipitation were treated as a gamma distribution in order to determine the top 2%, 1%, and 0.5% to define events as unusual, rare, and extreme...
Habitat use and home range of American bitterns (Botuarus lentiginosus) and monitoring of inconspicuous marsh birds in northwest Minnesota
(University of Missouri--Columbia, 2007)
Information on habitat use of the American Bittern (Botaurus lentiginosus) and a statistically valid survey design for monitoring changes in populations of inconspicuous marsh birds, which include American and Least Bitterns ...
The effects of overstory retention on species composition and height growth following clearcut and group selection regeneration harvests in the Missouri Ozark Highlands
(University of Missouri--Columbia, 2019)
The objectives of this study focus on whether treatment and aspect significantly influence tree regeneration. This study utilizes data from 16-year-old clearcuts and group openings within the Missouri Ozarks to assess the height and quantity...
