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...
A multi-configuration evaluation of the soil and water assessment tool (SWAT) in a mixed land use watershed in the central U.S.A.
(University of Missouri--Columbia, 2011)
. Watershed and soil resolution had negligible impact; climate input had considerable impact. Single climate station input is best used for applications requiring monthly predictions; distributed climate station input is needed for daily predictions. SWAT...
Overcoming the Challenges of Using Unmanned Aircraft for Bridge Inspections
(2016)
Applications for small unmanned aerial vehicles have exploded over the past
decade. Small size, maneuverability, low cost, and versatility enable utilization for applications
not readily accessible by traditional manned ...
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...
Delineation of critical management areas at plot, field, and watershed scales for claypan soils
(University of Missouri--Columbia, 2010)
and water quality and given rise to non-point source pollutants. The claypan soil region of Missouri has a high runoff potential that increases the possibility of transport of non-point source pollutants to downstream sites. The Agricultural Policy...
Rivers running through : an urban environmental history of the Kansas Cities and the Missouri River
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] An environmental history of Kansas City and an urban history of the Missouri River, this dissertation shows how interconnected the city and the river were through the twentieth...
The portfolio problem in agricultural cooperatives: an integrated framework
(University of Missouri--Columbia, 2005)
A portfolio problem within agricultural cooperatives arises as a result of the traditional cooperative's property rights structure. As members' investment is tied to patronage, this traditional structure prevents them from adjusting cooperative...
Establishing pin oak reproduction in bottomland forests in southeastern Missouri
(University of Missouri--Columbia, 2010)
In pin oak (Quercus palustris Muenchh.) bottomland forests in southeast Missouri, we revisited clearcuts, shelterwood harvests, and controls within the Mingo Basin. Seventeen years later, we found significant changes, in both the change in basal...
Effects of low crude protein diets with amino acid supplementation on broiler performance in the starter period
(University of Missouri--Columbia, 2009)
A series of experiments were conducted to examine the effects of feeding low crude protein (CP) corn and soybean meal diets with crystalline amino acid supplementation to broilers from 0-3 weeks of age. It was hypothesized that these diets would...
Development of high protein soybean experimental lines with enhanced sulfur amino acid content
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Soybean is one of the most important field crops grown in the United States. Commercial soybeans contain about 36 - 40 [percent] protein and 18 - 20 [percent] oil, by dry weight...
Desegregation at Kansas City's Central High School: Illuminating the African American student experience through oral history
(2014-07-17)
Central High School, the oldest high school in Kansas City, serves as an example of how radically education in Kansas City, Missouri, has changed over the course of the last 150 years. Beginning as part of Kansas City, Missouri’s, segregated public...
Integrating cover crops into crop rotations in upstate Missouri
(University of Missouri--Columbia, 2018)
"There is an increasing emphasis on management strategies such as reduced tillage, use of cover crops, and implementation of conservation practices (i.e. terraces, no-till, and cropping systems) in Missouri cropping systems. By combining best...
Data-Driven Modeling of the Lake Chad Basin Hydrologic Systems
(University of Missouri -- Kansas City, 2019)
The drying of the Lake, located in Central Africa, is one example of a water crisis,
which requires more research and studies. The lake has been progressively shrinking since the
1960s due to climate change and anthropogenic ...
Electromagnetic effects on soybeans
(University of Missouri--Columbia, 2007)
on Magellan for repeat experiments were inconclusive at best. Germination for case studies with two hundred samples showed marked improvement but the statistical significance for much larger sample (1000 seeds) decreased. All the experiments were conducted...
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...

(University of Missouri--Columbia, 2008)
and 2006. A quantitative content analysis of 456 stories, a qualitative framing analysis on a subset of that coverage, and interviews with a science or medical reporter at each newspaper provided converging lines of inquiry. This study finds that one...
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 ...
Small newspapers, big changes: awareness of market-driven journalism and consequences for community newspapers
