Centromere function and evolution in maize (Zea mays)
(University of Missouri--Columbia, 2006)
A dispensable supernumerary chromosome present in maize, the B chromosome, was the focus of many centromere studies. First, I examine the variation in copy number of centromeric elements and other repeats among different ...
Seasonality and elevational migration in an Andean bird community
(University of Missouri--Columbia, 2010)
Life history strategies of many birds in the Neotropics remain poorly known. In particular, details on the seasonal movements of individuals and populations within the Neotropics remain largely unknown, including short-distance ...
Amphibians as wetland restoration indicators on Wetlands Reserve Program sites in Lower Grand River basin, Missouri
(University of Missouri--Columbia, 2010)
My research goal was to determine if hydrological and biological wetland characteristics had been restored to Wetlands Reserve Program (WRP) sites in the Lower Grand River basin, north-central Missouri, as indicated by distribution, recruitment...
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 ...
Regulation of plant development in Arabidopsis
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The development of a complex organism, such as a plant, requires the function of multiple pathways that regulate various aspects of the developmental process. Here pathways...
Agent-based modeling of seasonal population movement and the spread of the 1918-1919 flu: the effect on a small community
(University of Missouri--Columbia, 2004)
Agent-based modeling provides a new approach to the study of virgin soil epidemics like the 1918-1919 flu. By using this bottom-up simulation approach, a landscape can be created and populated with a heterogeneous group ...
Patria o muerte: ideograph and metanarrative in Cuban state-produced media during the battle of ideas
(University of Missouri--Columbia, 2009)
Cuba's state-run media outlets have long acted as conduits for the construction and reinforcement of Revolutionary ideology. This was particularly true during the Battle of Ideas, an ideological campaign that aimed to ...
Innate immunity in Arabidopsis : molecular mechanisms of HOPA1 and AVRRS4 - specific disease resistance signaling pathways
(University of Missouri--Columbia, 2009)
Plants have evolved several layers of predetermined defenses, collectively called the innate immune system. Because of its effectiveness effector-triggered immunity (ETI) is a highly valuable agronomic trait. However, ETI ...
Characterization of resistance to tombusvirus in nicotiana species
(University of Missouri--Columbia, 2009)
Our lab studies resistance to tombusviruses such as Tomato bushy stunt virus (TBSV), Cymbidium ringspot virus (CymRSV), and Cucumber necrosis virus (CNV) in Nicotiana species, according to the ''gene for gene'' model, which ...
Damn with faint praise : a historical commentary on Plutarch's On the fortune or virtue of Alexander the Great 1
(University of Missouri--Columbia, 2009)
Plutarch's On the Fortune or Virtue of Alexander the Great is as much a revelation of Plutarch's philosophical thought as it is a display of his rhetorical skill. Writing during the Second Sophistic movement, Plutarch ...
Alleviation of heat stress with Tasco in dairy cows
(University of Missouri--Columbia, 2010)
The present study determined the impact of Tasco, Ascophyllum nodosum, on heat stress in dairy cows. Thirty-two Holstein cows were utilized in a randomized complete block design, during 63 days in summer 2008. Feed intake, ...
Pottery production at Fort Hill (27CH85) a seventeenth-century refugee community in northern New England
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This thesis formulates a model for explaining stylistic, functional, and compositional diversity in ceramic artifacts produced during the contact period (A.D. 1590...
An ecological systems approach to reduce children's encounters with obscenity on the internet
(University of Missouri--Columbia, 2007)
This dissertation explores how to reduce children's encounters with obscenity on the Internet. Congress has been trying to shield children from encountering online obscenity and some of Congress' attempts failed because ...
