Simultaneous quantitation of Escherichia coli O157:H7, salmonella and shigella in ground beef by multiplex real-time PCR and immunomagnetic separation
(University of Missouri--Columbia, 2006)
outbreaks. Genomic DNA for the real-time PCR was extracted by the boiling method. Three sets of primers and corresponding TaqMan® probes were designed to target these three pathogens. Multiplex real-time PCR was carried out with TaqMan® Universal PCR Master...
Soil surface-seal measurement using high-resolution x-ray computed tomography (HRCT)
(University of Missouri--Columbia, 2006)
Rainfall on bare soil breaks soil aggregates, detaching particles, plugging pores and decreasing porosity in the top few mm of soil. This reduces hydraulic conductivity and increases runoff through a process known as surface ...
An Anatomy of a Cartel: The National Industrial Recovery Act of 1933 and the Compliance Crisis of 1934
(Research in Economic History, 2008)
This paper explores the nature and causes of the cartel compliance crisis that befell the National Industrial Recovery Act (NIRA) one year after its passage in 1933. We employ a simple game-theoretic model of the NIRA's ...
Characterization of a diverse USDA collection of wild soybean (glycine soja siebold & zucc.) accessions and subsequent mapping for seed composition and agronomic traits in a RIL population
(University of Missouri--Columbia, 2018)
the phenotypic diversity within a core collection of 80 G. soja plant introductions (PIs) in the United States Department of Agriculture National Genetic Resources Program that were collected in China, Japan, Russia, and South Korea, and to analyze...
Response of beef cattle selected for tolerance to tall fescue toxicosis
(University of Missouri--Columbia, 2019)
Tall fescue (Schedonorus arundinaceus (Schreb.) Dumort.) infected with the endophytic fungus, Epichlooجا coenophiala [(Morgan-Jones & W. Gams) C.W. Bacon & Schardl, comb. nov.] produces ergot alkaloids that result in a ...
The effects of state term limits on natural resource spending
(University of Missouri--Columbia, 2022)
This paper examines how term limits operate as an institutional characteristic of state legislative branches. First, I describe the history of the term limit movement to contextualize public opinion. I then review relevant ...
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...
Amphibian metamorphosis and juvenile terrestrial performance following chronic cadmium exposure in the aquatic environment
(University of Missouri--Columbia, 2005)
[mu]g Cd/L. The experimental endpoints were survival, mass and age at metamorphosis, and whole body Cd content. Both species had a decrease in survival and increase in larval period and Cd content with increasing aqueous Cd concentration. However...
Insight into the roles of prescribed fire and hardwood competition in the survival and growth of shortleaf pine throughout its early life
(University of Missouri--Columbia, 2023)
pine is competition from hardwoods. In Missouri specifically, many sites formerly occupied by shortleaf pine are now dominated by oak species with established and highly competitive advanced regeneration. Prescribed fire is a tool often used...
Three essays on the Conservation Reserve Program
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Over 35 years, the Conservation Reserve Program (CRP) has provided a variety of envi-ronmental benefits, reducing run-off of sediment, nitrogen, and phosphorus...
Development and evaluation of pattern recognition habitat models for the ruffed grouse, gray squirrel, and fox squirrel in Missouri
(University of Missouri -- Columbia., 1987)
Pattern recognition (PATREC) models are single-species models that use habitat characteristics to arrive at an estimation of population abundance. Currently, personnel of the Mark Twain National Forest in Missouri are using this type of model as a...
Landscape and inchannel factors affecting the distribution and abundance of riverine smallmouth bass in Missouri
(University of Missouri--Columbia, 2008)
I developed a series of spatially-nested research objectives to identify habitat elements related to the distribution and abundance of riverine smallmouth bass Micropterus dolomieu in Missouri. The range of smallmouth bass was identified using a few...
Biomineralizers from the proterozoic to today : assessing taxonomy and paleoecology through the lens of taphonomy
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The onset of metazoan predation is presumed to have triggered an evolutionary arms race of prey defenses, including the advent of biomineralization. Escalating biological...
Potential diagnostic methods and nutritional changes to combat bovine respiratory disease in receiving cattle

Bovine respiratory disease (BRD) accounts for up to 70 percent of health disruptions and $500 million in associated medical costs and production losses, thus receiving considerable attention from cattle health personnel ...
Measuring and comparing the spatiotemporal evolution of accident hot spots
(University of Missouri--Columbia, 2022)
One reality of transportation systems is that vehicular accidents can happen practically anywhere and at any time. An increasing body of research suggests though that spatial and/or temporal dependencies (i.e., clusters ...
