Urban runoff simulation and prediction: How do land use and land cover change patterning and geospatial data quality impact model outcome?
(2020)
With the increase in global urbanization, satellite imagery and other types of geospatial data have been extensively used in urban landscape change research, which includes environmental modeling in order to assess the ...
The role of terrrestrial habitat in the population dynamics and conservation of pond-breeding amphibians
(University of Missouri--Columbia, 2007)
-structured demographic models for two pond-breeding amphibian species and used these models to determine the potential effects of a range of core terrestrial habitat areas on population size and persistence. I next carried out field experiments designed to improve model...
A method of sociological investigation
(University of Missouri--Columbia, 1913)
"It is the purpose of the author of this thesis to present, from his limited experience as a social surveyor and from a rather extended study of social surveys, the meaning and value of the survey method to the science of sociology." --Text taken...
Missouri soybean handbook (1987)
(University of Missouri. Extension Division, 1987)
"Understanding the growth and development of a soybean plant can be useful in making many management decisions on soybean production. This presentation draws heavily on Iowa State University Cooperative Extension publications SR 53 'How a Soybean...
Evaluation of a solid-liquid manure separation operation
(University of Missouri--Columbia, 2018)
, and barn construction and operating costs. A full-scale barn in Missouri was closely monitored to perform these objectives. Laboratory scale pretreatments and filtrations were conducted to evaluate the practicality of nutrient/water recycling from...
Effects of prescribed fire and timber harvest on terrestrial salamander abundance, behavior, and microhabitat use
(University of Missouri--Columbia, 2014)
surveys for three years and used a statistical modeling approach that accounted for the tendency of terrestrial salamanders to be belowground and unavailable for surveys. I found that terrestrial salamander density at our Missouri Ozark study site ranged...
Ecology and management of oak regeneration in bottomland hardwood forests in Missouri
(University of Missouri--Columbia, 2023)
Managing oak regeneration is a challenge in bottomland hardwood forests due to variations in acorn production, acorn predation, competition with other species, and flooding. This study was designed to investigate bottomland ...
Evaluation and development of first order fire effects mortality model predictions for eastern hardwood forests
(University of Missouri--Columbia, 2018)
The First Order Fire Effects Model (FOFEM) is a useful tool for predicting fire-induced mortality in western coniferous forests. However, it lacks robust models for eastern hardwood species. Managers in the eastern United ...
An ecological study of American Ginseng (Panax quinquefolius L.) in the Missouri Ozark Highlands: effects of herbivory and harvest, ecological characterization and wild simulated cultivation
(University of Missouri--Columbia, 2006)
Matrix population analysis was used to analyze eight years of demographic data from six American ginseng (Panax quinquefolius L.) populations in east-central Missouri to examine effects of herbivory by white-tailed deer (Odocoileus virginianus Zimm...
Effects of Selected Contaminants on the Physical, Chemical, and Geotechnical Properties of Aquifer Solid
(2014)
The primary objective of this study was to investigate the potential effects of hydrocarbons on the geotechnical properties of sand. A series of laboratory experiments were carried out to ascertain the influence of some common and widespread organic...
Canopy recruitment dynamics in naturally regenerated longleaf pine (pinus palustris) woodlands
(University of Missouri--Columbia, 2017)
The ecological and cultural values of the longleaf pine (Pinus palustris) ecosystem, in combination with an approximately 97 percent loss in historic range, has led to increasing interest in ecosystem restoration and ...
2009 Missouri Pest Management Guide : corn, grain sorghum, soybean, winter wheat (2008)
(University of Missouri. Extension Division, 2008)
at MU and elsewhere. Pesticides named in this publication are registered by the U.S. Environmental Protection Agency and the Missouri Department of Agriculture. Trade names are included with the understanding that no discrimination is intended...
Monitoring of an urban level spreader as part of the collaborative adaptive management process
(University of Missouri--Columbia, 2020)
Irregular flows, such as the high flows caused by stormwater runoff after a rain event are a major cause of stream impairment in urbanized watersheds. The Hinkson Creek CAM (Collaborative Adaptive Management) approach is ...
Tensile strength, shear strength, and effective stress for unsaturated sand
(University of Missouri--Columbia, 2006)
It is generally accepted in geotechnical engineering that non-cohesive materials such as sands exhibit no or negligible tensile strength. However, there is significant evidence that interparticle forces arising from capillary ...
Site preparation for longleaf pine restoration on hydric sites : stand development and ground flora responses 15 years after planting
(University of Missouri--Columbia, 2019)
control treatments (chopping or herbicide) with three soil manipulation treatments (flat [no treatment], mounding, or bedding), and an herbicide-chopping-bedding treatment. Our objectives were to determine the long-term impacts of site preparation...
Solidarity infrastructure : gender and race solidarity and cross-class coalitions in the Kansas City general strike of 1918
(University of Missouri--Columbia, 2021)
This dissertation investigates alliances across gender, race, and class in the dynamics of working class solidarity. The analysis examines the geographically bounded organizational networks, community spatial organization, ...
Developing a modern recycled mix design and automatic pavement monitoring system
(University of Missouri--Columbia, 2021)
. To this end, the performance of eighteen different dense-graded asphalt mixtures paved in Missouri were investigated. The sections contain a wide range of reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS), and different types of additives...
Tales of an 'invisible' life stage : survival and physiology among terrestrial juvenile ambystomatid salamanders
(University of Missouri--Columbia, 2019)
of the many amphibian species for which stage-specific data are lacking. Next, I reared larvae of five species (A. annulatum, A. maculatum, A. opacum, A. talpoideum, and A. texanum) from populations along an ~200 km latitudinal gradient in Missouri, USA...
Persistence of plague : determining which environmental factors contribute to maintenance of Yersinia pestis within sylvatic cycles
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 5/1/2024] Plague is a prioritized zoonotic disease caused by Yersinia pestis, a gram-negative bacterium. Sylvatic cycles of rodent host and flea vectors have established endemic foci responsible for the ...
