Restoration treatments and regeneration dynamics in East Texas mixed wood forests
(University of Missouri--Columbia, 2023)
Extensive harvesting, fire exclusion, and plantation forestry altered composition and structure, and thus function and habitat values of east Texas Pineywoods uplands. Upland restoration efforts are made difficult by the ...
Effects of riparian buffer width on stream salamander populations in the southern Appalachian Mountains
(University of Missouri--Columbia, 2008)
Salamanders in the Appalachian region have been extensively studied, but the majority of research assessing the impacts of logging has focused on terrestrial species that are not dependent on stream habitats for egg deposition or larval development...
Investigation upon the nitrogen, phosphorus, sulfur, and ash content of three beef animals, with special study upon the forms of sulfur
(University of Missouri--Columbia, 1917)
This thesis explores the chemical composition of beef cattle, with special attention given to nitrogen, phosphorus, sulfur, and ash content. A review of previous research is provided as well as a description of an experiment carried out...
Effects of dormant season soil flooding and soil temperature on pin oak (Quercus palustris) seedlings
(University of Missouri--Columbia, 2022)
. During soil flooding, root mass was significantly less in flooded seedlings than those that were not flooded. However, following drainage this difference was no longer present. By the end of the experiment, seedlings that received flooding exhibited...
Playa wetland plant and soil response to predicted climate and land use change in the southern Great Plains
(University of Missouri--Columbia, 2019)
. The research included fourexperiments with various temperature, hydroperiod, and nitrogen treatments to simulate climate and land use change projections. In the first study,atemperature-controlled growth chamber experiment was used to evaluate treatment effects...

(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The spread of infectious disease among human populations is heavily influenced by social relationships and interactions between humans. This project examines the role of social...
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 functional morphology...
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...
Evolution of the Bahamian coastal environment of San Salvador Island over the last 3,500 years based on triangle pond sediment cores
(2014-07-25)
The multiproxy examination of ten soft sediment cores extracted from Triangle Pond
was used in order to establish alterations in the northwestern coastal environment of San
Salvador Island, The Bahamas over the last 3,500 ...
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...

A Python-based GIS simulation of a water balance for wetland decision-making
(University of Missouri--Columbia, 2021)
wetland site to determine the potential existence of the excess water component. The study area is a location within Pershing State Park within Linn County, Missouri. Three goals have been set in this research in order to achieve the ultimate goal...
Estimation of demand parameters : an empirical analysis of consumer behavior in the United States
(University of Missouri--Columbia, 1971)
Demand analysis is a key element of economics. It has the attractive feature of being important in theory as well as in application. Its purpose is to explain consumer behavior in the market place, i.e., demand analysis ...
