Federal laws protecting groundwater and surface water [eq 0022] (2017)
(University of Missouri--Columbia. Extension Division, 2017)
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...
Operational analysis of cross-country trips on rail in Vietnam
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The analysis of current transit conditions is vital for planning and forecasting future transit demand. Previous analyses of Vietnam railways have been limited in both data...
The politics of CO2 emissions
(University of Missouri--Columbia, 2020)
in responding to tackling climate change problems. Therefore, investment and strategic intervention for maintaining institutional quality and adopting institutional reform where needed merit more in-depth research initiatives....
GIS-based, python modeling of the spatial and temporal distribution of water on the landscape for wetlands decision making
(University of Missouri--Columbia, 2020)
Wetlands provide many benefits for humans and the natural environment, but land use changes have reduced their number and areal extent. Interest has grown in examining surface water distribution both spatially and temporally, ...
Three essays on the economics of pesticide use
(University of Missouri--Columbia, 2022)
Pesticides primarily benefit humans in terms of protection of food production, prevention of diseases, and weed control, but also potentially harm people and the environment. Given increasing current interest in human health and environmental...
Studies of ruminant digestion, ecology, and evolution
(University of Missouri--Columbia, 2008)
This thesis examines ruminant digestion, ecology, and evolution, particularly where they can improve livestock production systems. We performed an experiment that estimated ruminal in situ degradation parameter values of ...
Estimating Water Quality, Air Quality, and Soil Carbon Benefits of the Conservation Reserve Program
(Food and Agricultural Policy Research Institute (FAPRI) at the University of Missouri-Columbia, 2007-01)
This report estimates how field and buffer practices affect the amount of soil and nutrients leaving the field.
Establishment of native plant species for livestock forage in silvopasture systems
(University of Missouri--Columbia, 2022)
the cool season grasses. All remaining forages were no-till drilled each winter prior to the growing season. Environmental (PAR, ambient temperature, soil water content), plant community composition, herbage accumulation, and forage quality data were...
Adoption of nutrient management practices
(University of Missouri--Columbia, 2008)
Off-farm income has recently been incorporated into the analysis of technology adoption, due to its increasing share in total farm household income in the U.S. Previous studies, however, found inconsistent results with ...
An evaluation of pre- and post-timber harvest water quality in low-order streams in the Missouri Ozarks
(University of Missouri--Columbia, 2009)
Missouri Department of Conservation's (MDC) best management practices (BMPs) for Regenerative Oak Clear Cutting (ROCC) practice was evaluated on effectiveness to preserve downstream water quality. Fifteen sites, located on MDC lands in Shannon...
Evaluating phytochemical contributions to atrazine degradation
(University of Missouri--Columbia, 2020)
Surface water contamination from the herbicide atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) has been a concern for many years. The use of vegetated buffer strips (VBS) is known to improve water quality but the use of specific...
Investigation of CO2 capture systems, Lewis acid-base pairs, and oscillating reactions with electronic structure theory and kinetics-based approaches
(University of Missouri--Columbia, 2020)
the capture of CO2 by small alkylamines. The quality of that discussion was tested directly with the work described in Chapter 2. The work that led to Chapter 2 was an enormous learning experience; it was amazing to see all the pieces of the complicated multi...
Great Lakes lake trout early mortality syndrome (EMS) : contaminants, thiamin status, and their possible interaction
(University of Missouri--Columbia, 2006)
Salmonid populations in the Great Lakes experienced a decline in the early twentieth century, presumably due to over-fishing combined with the introduction of exotic parasites such as the sea lamprey. Despite intensive ...
The economics of land disposal of municipal effluent
(University of Missouri--Columbia, 1972)
"Objectives of the study: The study attempts to analyze the possibilities of utilizing wastewater for agricultural production, particularly involving the use of irrigation. Various economic questions concerning the economics ...
Organic groundwater contamination evaluation and prediction
(1983)
Adsorption of two organic compounds, Trichloroethylene (TCE) and Pentachlorophenol (PCP), on several Missouri soils were determined. The soils used were of the Coppock, Parsons, Putnam, Grundy and Lebanon series. TCE concentrations were determined...
Impact of woody biomass production and biopower generation on US forests
(University of Missouri--Columbia, 2022)
This dissertation presents a study of environmental impact of woody biomass production and consumption on the eastern US forests. The first part is concerned with the impact of the exponential growth in trading of US pelletized wood fibers triggered...
Agroforestry and cover crops for improving surface water and groundwater quality
(University of Missouri--Columbia, 2023)
and human health. Conservation practices prevent water pollution by reducing runoff and retaining sediment and nutrients in agricultural watersheds. Since the environmental effects of agricultural pollution are severe and cost plenty of resources...
Bridging the gap : comparative analysis of a gap filling X-band radar QPE algorithms and their implications for nowcasting and hydrological modeling
(University of Missouri--Columbia, 2023)
Accurate Quantitative Precipitation Estimations (QPE) are foundational for hydrological modeling and proactive watershed management. This research examines how a single X-Band radar bridges the gap in QPE estimation and ...
