Assemblage structure and shallow-water habitat use by small-bodied fishes at lower Missouri River sandbars
(University of Missouri--Columbia, 2007)
Populations of many native big-river fishes have declined since channelization and flow regulation contributed to losses of shallow-water habitat (SWH) on lower Missouri River (LMOR). Existing point and wing-dike sandbars represent a potentially...
Impacts of municipal wastewater effluent on seed banks, chemistry, and microorganisms of soils excavated from wetland impoundments designated for wildlife
(University of Missouri--Columbia, 2009)
To evaluate the effects of municipal wastewater effluent (WWE) and Missouri River water (MOR) as irrigation sources on soil chemistry, seed banks, and microorganisms, a field study was conducted in conjunction with a set of greenhouse studies...
Theoretical and experimental study of an evaporative cooler embedded with parallel plates
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In the current investigation, a theoretical model predicting the temperature variation of ambient air flowing through an evaporative cooler embedded with parallel plates...
Spatial, temporal, and petrogenetic relationships of basaltic and lamprophyric dikes and sills of the Raton Basin, southern Colorado and northern New Mexico
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Alkali basalts and lamprophyres commonly occur as sheet intrusions along the flanks of continental rifts. The Raton Basin, on the eastern shoulder of the Rio Grande rift, is host...
Are structural changes in the agri-food sector causing the instability of parochial ag-producers?
(University of Missouri--Columbia, 2009)
Parochial (Amish and Mennonites) agriculture producers have been known for their stability (historically large numbers) (Kollmorgen, 1943). Though, more recently, the percentage of parochial members who are ag-producers has been steadily declining...
Effects of prescribed burning in Missouri Ozark upland forests
(University of Missouri--Columbia, 2007)
Prescribed fire is used in Missouri to achieve various silvicultural goals, but the use of burning in upland Ozark forests raises many questions that research has yet to answer. The purpose of this study is to examine the effects of prescribed...
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...
Synergy of wide-field infrared survey explorer (WISE) and the Sloan Digital Sky Survey in Stripe 82
(University of Missouri--Columbia, 2018)
from the Sloan Digital Sky Survey (SDSS) Stripe 82 and the infrared data from the Wide-field Infrared Survey Explorer (WISE), and constructs a unique catalog of galaxies that have their spectral energy distributions (SEDs) measured consistently from 0.3...
Effect of plagioclase crystallization on liquid and magma viscosity in the Anorthite-diopside-dorsterite-quartz system
(University of Missouri--Columbia, 2006)
SiO2 (CMAS) glasses were synthesized as analogs for dacitic and basaltic lavas. Liquid viscosities were measured between 101 and 1013 Pa s, over the temperature range of approximately 1600 to 700⁰C, using concentric cylinder ...
Importance of agritourism for agripreneur goal accomplishment
(University of Missouri--Columbia, 2010)
associated with the importance of agritourism in accomplishment within four goal dimensions via descriptive-relational survey research. Agritourism farms in Missouri are in the business of agricultural production, rather than maintaining their land...
Effects of levels of statistics and the role of number anxiety on perceived story credibility and personal involvement
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The purpose of this research is to examine effects of levels of statistics on perceived story credibility and personal involvement and the role of number anxiety on these results...
Surface and deep water circulation in late Cretaceous North Atlantic greenhouse ocean
(University of Missouri--Columbia, 2009)
This research provides the first of its kind empirical data regarding the evolution of Maastrichtian surface to deep ocean circulation in the North Atlantic. Differences in foraminiferal abundances and oxygen and carbon ...
The Spoon Toe Site (11MG179): Middle Woodland gardening in the lower Illinois River Valley
(University of Missouri--Columbia, 2005)
This thesis is an examination of archaeobotanical remains from the Spoon Toe site, a Middle Woodland Massey phase site located in the uplands above the Lower Illinois River valley in Morgan County in western Illinois. The ...
Nutrients, chlorophyll and bacterial fecal indicators in coves and open water areas of Lake of the Ozarks, Missouri
(University of Missouri--Columbia, 2009)
Urban development and use of septic tanks in porous soils of Lake of the Ozarks poses a threat to public health via leaching into drinking wells and coves used for swimming. During 2 summers, phosphorus (TP), nitrogen (TN), ...
Development of implementation methods of water quality trading policy : using the Hydrological simulation program-Fortran (HSPF)
(University of Missouri--Columbia, 2010)
between different locations within a watershed, as long as water quality standards are not violated along the stream. Many pilot programs and projects have generated useful information on how to implement water quality trading, but the number of actual...
Seismic anisotropy beneath the southern Puna Plateau
(University of Missouri--Columbia, 2009)
The central Andean plateau is a prime region to study mantle flow above an active plateau margin, where it has been suggested that a link exists between plateau uplift and removal of the lower crust and lithospheric mantle. ...
Flexure shear response in fatigue of fiber reinforced concrete beams with FRP tensile reinforcement
(University of Missouri--Columbia, 2007)
of polypropylene fibers by volume, individual compressive tests were performed on both lab-mix and ready mix concrete specimens. In the lab, concrete mixes with 0.0%, 0.5%, and 1.0% by volume, fibrillated polypropylene fibers were produced. Along with these...
Wildlife response to spatial and temporal changes in forest habitat
(University of Missouri--Columbia, 2008)
A common goal in land-management planning is to describe the relationship between management actions, vegetation and wildlife habitat conditions for large landscapes. Achieving this goal can be challenging because ecological ...
