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 ...
Administrative behavior : an annotated bibliography with emphasis on public administration
(University of Missouri--Columbia. Extension Division, 1968)
"No new observation is being made when it is said that information retrieval is one of the problems which academicians and practitioners alike find most pressing. This bibliography of research abstracts is designed to facilitate the location...
Sustainable management of invasive species
(University of Missouri--Columbia, 2023)
invasions. The main objectives of this dissertation were to: 1) evaluate the efficacy of an attract-and-kill strategy targeting Japanese beetle, 2) quantify how attract-and-kill impacts arthropod short- distance dispersal in an agricultural setting, and 3...
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...
Macroinvertebrate assemblage composition along a longitudinal multiple-land-use gradient in a midwestern stream
(University of Missouri--Columbia, 2012)
Land use changes often alter hydrogeomorphology and hydrologic flow regimes, which can adversely impact stream aquatic biota. Hinkson Creek Watershed (HCW, 231km2) located in Boone County, central Missouri, is comprised of 50% agriculture, 26...
Amphibian metamorphosis and juvenile terrestrial performance following chronic cadmium exposure in the aquatic environment
(University of Missouri--Columbia, 2005)
degradation and amphibian declines. Manipulative experiments were conducted to investigate the performance (i.e., growth, survival) of amphibians that metamorphose from chemically-contaminated aquatic breeding sites. The heavy metal cadmium (Cd) was selected...
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...
Effects of prescribed fire and timber harvest on terrestrial salamander abundance, behavior, and microhabitat use
(University of Missouri--Columbia, 2014)
surveys for three years and used a statistical modeling approach that accounted for the tendency of terrestrial salamanders to be belowground and unavailable for surveys. I found that terrestrial salamander density at our Missouri Ozark study site ranged...
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 ...
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...
Effects of a consortia probiotic inoculant on soil microorganisms and impacts on autoinducers employed in quorum sensing
(University of Missouri--Columbia, 2013)
Disease control in plant agriculture is largely achieved through application of various antimicrobials. Manipulation of indigenous soil microbial communities received attention as it promises improved pathogen control and enhanced plant outputs...
Monetary Policies for Full Employment and Price Stability in Saudi Arabia: An Endogenous Money Approach
(University of Missouri--Kansas City, 2017)
Despite being a relatively young and prosperous country, Saudi Arabia has recently suffered from substantial rises in unemployment. This dissertation thus examines the root
causes for the rise in unemployment and limited ...
Managerial perceptions and responses to climate change in Missouri state parks and historic sites
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Climate change has been described as one of the greatest, long-term challenges facing modern society. Its impacts range from alteration of ecosystem structure and function...
Impacts of suspended and deposited sediment on benthic invertebrates and fishes in a Missouri Ozark stream
(University of Missouri--Columbia, 2006)
Sediment is suspected in the decline of sensitive-aquatic organisms in the Osage River basin of Missouri. In this study, I monitored sediment dynamics and evaluated corresponding linkages with benthic invertebrate and fish assemblages as it related...
Nectar in nicotiana : pollinator associations, sources of variation, and evolutionary consequences
(University of Missouri--Columbia, 2007)
genetic basis. However, some differences in trait means and genotype by environment interactions were detected between the novel environment in which the experiment was conducted (Missouri), and the ancestral habitat of this species (Brazil). Therefore...
An economic analysis of the agricultural development potential for Southern Honduras
(University of Missouri--Columbia, 1975)
for various resources r which would provide guidance for making investment decisions; and (3) to derive policy recommendations for the purpose of agricultural development in Southern Honduras. A survey of 449 randomly selected sample farms, including 686...
