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...
Response of natural and artificial pin oak reproduction to mid- and understory removal in a bottomland hardwood forest
(University of Missouri--Columbia, 2006)
bottomland forest sites in southeastern Missouri. The mid- and understory removal treatment increased the amount of photosynthetically active radiation reaching the understory from 3 percent of full sunlight to 16 percent of full sunlight. This increase...
Roadway effects on the hydrologic regime of temporary wetlands in the Missouri River floodplain in Missouri
(University of Missouri--Columbia, 2005)
on the hydrologic regime of temporary wetland basins within the agricultural landscape of the Missouri River floodplain from Hartsburg to Independence, Missouri. This study is part of a larger existing research project designed by the Missouri Department...
Power in the garden : exploring the lives of Missouri farm women and their vegetable gardens during the Great Depression
(University of Missouri--Columbia, 2007)
Today, when fresh, canned, and frozen vegetables are plentiful and taken for granted, the home vegetable garden is regarded as something between a hobby and a luxury. But in the Great Depression of the 1930s, the household ...
A multi-scale investigation of ecologically relevant effects of agricultural runoff on amphibians
(University of Missouri--Columbia, 2008)
Modification of landscapes for agricultural production can introduce agrochemicals into surface waters and degrade aquatic habitats used by many amphibians for breeding and larval development. Although many ecotoxicological studies have shown...
Fire risk assessment of the western portion of the central hardwoods forest region
(University of Missouri--Columbia, 2008)
This study examined how fire risk, a combination of fuels conditions and fire probabilities, varied across a large portion of Missouri, Illinois, and Indiana. Case studies were conducted to evaluate the fuel loading variability in Missouri Ozark...
Long-term study of successional trends in an oak-dominated forest of central Missouri
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Changes in species composition and forest structure were studied over a 36-year period in the Baskett Research and Education Area (BREA) in central Missouri. Permanent plots were...
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 comparison of grant-funded outdoor classrooms in rural and nonrural Missouri schools
(University of Missouri--Columbia, 2009)
This study addressed the question: How do outdoor classrooms in rural and nonrural areas of Missouri compare? Data was collected from applications for state funded grants awarded from 2004- 2006 to elementary schools in rural and nonrural areas...
Land cover classification from satellite imagery, and its applications in cellular network planning
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] To further increase the classification accuracies, radar image processing techniques were investigated to preprocess the Radarsat data before classification. Eight processing...
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...
Economic Vulnerabilities and opportunities of Hispanics in non-metro Missouri
(Cambio Center, 2004)
Non-metro Missouri has observed a net in-migration in the last decennial period and a great part of these immigrants are Latinos. This research addresses the factors explaining vulnerabilities and economic opportunities of Latinos in non...
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 ...
Intraguild interactions between native and domestic carnivores in central India
(University of Missouri--Columbia, 2008)
Bustard Sanctuary, Maharashtra, India and assessed resource selection based on landcover characteristics. Indian foxes chose for grassland habitats at the scale of both landscape and home-range level and avoided human-dominated areas such as agricultural...
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...
