A quarterly econometric model of the United States beef sector
(University of Missouri--Columbia, 1982)
The United States beef sector has been modeled in many studies, perhaps, because beef represents a large proportion of the consumer food dollar and agriculture’s income. The predictive performance of these models has been, however, quite...
Winter bird densities and eastern wood-pewee breeding demography across a savanna-woodland-forest gradient in the Missouri Ozarks
(University of Missouri--Columbia, 2012)
and woodland is needed to inform management. Our objective was to determine densities of common winter migrants and resident birds in savannas, woodlands, and non-managed forests in the Missouri Ozark Highlands. We estimated detection probabilities...
Maternity roost selection of Indiana bats (myotis sodalis) and occupancy of two threatened myotine bat species on national wildlife refuges in northern Missouri
(University of Missouri--Columbia, 2020)
maternity habitat characteristics of the endangered Indiana bat (Myotis sodalis) in northern Missouri to identify factors that drive selection and 2) identify local- and landscape-scale habitat characteristics associated with occupancy of M. sodalis and M...
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...
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...
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...
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...
Drainage water management practices affect water quality, soil properties, and crop production
(University of Missouri--Columbia, 2023)
. This dissertation includes results from four studies conducted at the MU Greenley Research Center, Grace Greeley farm, and Ross Jones farm. Long-term, no-till research evaluated the influence of a wheat (Triticum aestivum L.), radish (Raphanus raphanistrum subsp...
Behavioral choice and demographic consequences of wood frog habitat selection in response to land use
(University of Missouri--Columbia, 2007)
, Missouri, and South Carolina are determining the effects of timber harvest on the persistence of amphibian populations. The purpose of my dissertation research was to define adult wood frog nonbreeding habitat in continuous oak-hickory forest...

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...
The value of in-breeding in the improvement of the domestic animals
(University of Missouri--Columbia, 1917)
In this paper I shall take the stand of a neutral, and all literature and available material of value upon the subject both for and against, will be studied with a view of determining our present knowledge of in-breeding ...
Rheological and morphological evolution of basaltic lava flows
(University of Missouri--Columbia, 2018)
the following research questions: (1) How does the rheology of active flows evolve during emplacement; and (2) How can we use flow morphology to infer the rheology of inactive flows? ... At Piton de La Fournaise (La R�union, FR DOM), I addressed the longstanding...
Assessing red wolf conservation based on analyses of habitat suitability and human perception of carnivores
(University of Missouri--Columbia, 2018)
research was published on the original wild red wolf population, a literature review of red wolf landscape use and suitability analyses was conducted to identify primary habitat metrics for inclusion. We examined how much of the overall landscape of the red...
