A test of differential GPS correction methods at Fort Huachuca, Arizona
(University of Missouri--Columbia, 2009)
in differential correction has previously proven unreliable. The effectiveness of base data acquired through use of a second field unit as an on-site base station was compared with the use of CORS. The accuracy of data differentially corrected using base data...
Three essays on phosphorus runoff and water quality
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Water pollution caused by nutrients, and the resulting eutrophication, have increased over time. This water pollution is increasingly caused by non-point source pollution, both...
Climate and land use effects on hydrologic processes and water allocation in a primarily rain-fed, agricultural watershed
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] There is a need to raise our understanding of the impact of climate variability and change on hydrologic processes at the watershed scale. This is important, particularly...
Upper Shoal Creek Watershed: Water Quality Analysis
(Food and Agricultural Policy Research Institute (FAPRI) at the University of Missouri-Columbia, 2004-02)
FAPRI, with significant input from the local community, has developed this analysis defining how current agricultural practices in the upper Shoal Creek Watershed affect water quality....
Cover crop effects on soil moisture dynamics & thermal properties
(University of Missouri--Columbia, 2021)
properties of a corn (Zea mays L.) cropping system. The study was conducted at the Elsberry Plant Material Center - USDA, Missouri, USA, with 1) no-till cover crop (NC), 2) conventional till no cover crop (CN), and 3) no-till no cover crop (NN) treatments. A...
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 ...
Effects of stress, genetics, and environment on microbiome composition in western corn rootworm (Diabrotica virgifera virgifera Leconte)
(University of Missouri--Columbia, 2023)
practice of cover cropping and no-till to improve belowground pest management. Food security in the future will rely on successful integration of sustainable management practices in agricultural systems to balance productivity and broader ecosystem...
Body size and shape in insular environments and applications of the island rule in biological anthropology
(University of Missouri--Columbia, 2021)
The discovery of small-bodied hominin fossils in 2004 on the island of Flores, Indonesia, unearthed a large debate within biological anthropology. This debate has exemplified that there are questions and research areas that biological...
The impact analysis of structural change in Korean agriculture with respect to the Korean-United States free trade agreement : dynamic simultaneous equation model approach
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The main objective of this study is the analysis of the impacts of the Korean-United States Free Trade Agreement. On April 2, 2007, Korea and the United States concluded a...
Development and validation of standardized sampling protocols for assessing freshwater mussel populations in Missouri
(University of Missouri--Columbia, 2017)
step in assessing populations. We surveyed 14 sites in the Meramec River Basin in East-central Missouri to determine the effectiveness of visual sampling methods and to determine the effects of habitat variability on the effectiveness of these methods...

(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 ...
