Development of implementation methods of water quality trading policy : using the Hydrological simulation program-Fortran (HSPF)
(University of Missouri--Columbia, 2010)
-fortran (HSPF) was used to estimate the hydrology and sediment loading throughout the Brush Creek, MO watershed for future land use development scenarios between upstream and downstream locations. Brush Creek does not have a proper monitoring station...
Overseeding annual ryegrass and cereal rye into soybean for winter forage and as a cover crop for weed control and soil conservation
(University of Missouri--Columbia, 2005)
Annual ryegrass (Lolium multiflorum Lam.) and cereal rye (Secale cereale L.) are two forages that fit well into mixed row crop/livestock operations as they can be used both as a cover crop and as a source of winter pasture. Few researchers have...
Quantifying riparian canopy energy attenuation and stream temperature using an energy balance approach
(University of Missouri--Columbia, 2011)
of the central U.S. Hydroclimate data were collected from two intensively instrumented stream reaches of opposite orthogonal compass orientation in a semi-karst watershed on the border of southern Missouri's Ozark region, USA, during the 2010 water year. Data...
Analysis of landscape characteristics surrounding deer vehicle accidents in St. Louis County, Missouri
(University of Missouri--Columbia, 2008)
). This study quantifies landscape factors that contribute to deer vehicle accidents in St. Louis County, Missouri, and provides a predictive model of areas in which DVA's would likely be found. Geographic Information Systems (GIS) was used to plot deer...
Conservation and ecology of breeding landbirds in a riparian restoration context
(University of Missouri--Columbia, 2006)
of floodplain forest restoration on a large, regulated river in an agricultural valley. I used infrared, time-lapse video to identify agriculture-associated nest predators as a primary source of nest mortality in the Sacramento River Valley, California. Then...
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...
Golden-cheeked warbler nest success and nest predators in urban and rural landscapes
(University of Missouri--Columbia, 2007)
We studied nesting success of Golden-cheeked Warblers (Dendroica chrysoparia) from 2005-2006 in urban and rural landscapes in central Texas. We used an information-theoretic approach to evaluate models representing hypotheses ...
Glyphosate resistance : pollen movement within a common ragweed (Ambrosia artemisiifolia L.) population and herbicide release from common waterhemp (Amaranthus rudis sauer) plants
(University of Missouri--Columbia, 2011)
Common ragweed and Common waterhemp are native, summer annual weeds distributed widely throughout the United States. Both weed species have developed resistance to the broad-spectrum herbicide glyphosate. Research was conducted to determine...
Beyond the border war : student civil rights activism at the University of Kansas and the University of Missouri, 1946-1954
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] This dissertation examines post-World War II student civil rights activism at two Midwestern college campuses, the University of Missouri (MU) and the University...
Using attitutudes and motivations to segment the landowner audience: a typology of family forest owners in the Missouri Ozarks and description of management and information behaviors
(University of Missouri--Columbia, 2005)
With 74% of Missouri's forestland controlled by family forest owners, understanding this ownership group is important to ensuring the sustainable management of the state's forests. Audience segmentation techniques can help us to understand...
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...
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...
Analysis of twenty-five years of heavy rainfall events in the Texas Hill Country
(University of Missouri--Columbia, 2008)
climate stations in the region; the period examined for this study was 1982-2006. Days with measurable precipitation were treated as a gamma distribution in order to determine the top 2%, 1%, and 0.5% to define events as unusual, rare, and extreme...
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...
Effects of forest fragmentation on reproductive effort and productivity of Indigo buntings (Passerina cyanea)
(University of Missouri--Columbia, 2005)
and offspring quality, I measured maternal condition and reproductive output of Indigo Buntings breeding in a fragmented and a contiguously forested landscape in Missouri. Renesting females had lower body condition than those that nested once successfully...
Assessment of a voluntary nonlead ammunition outreach program on midwestern national wildlife refuges
(University of Missouri--Columbia, 2020)
at four managed hunts, 29 semi-structured interviews of program staff, and an online survey of 325 NWR staff. Objectives were to (1) examine lead exposure risks and suggest communication strategies, (2) explore attitudes and experiences of NWR staff...
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...
