Changes in stable carbon isotopes of methane along a salinity gradient in a hypersaline microbial mat system
(University of Missouri--Columbia, 2007)
the mat. POM d13C values (-6.7 to -13.5 permil) and DIC d13C values (-1.4 to -9.6 permil) were similar to previously reported values. However, there are no prior reports of methane d13C values within the mats, and we found considerable variability among...
Resolving space-time strain paths of the Panamint and Cottonwood Mountains, eastern California, through bedrock thermochronology and detrital geochronology
(University of Missouri--Columbia, 2020)
The landscape in Death Valley region is the result of a complex history that includes Miocene Basin and Range extension and Miocene to recent transtension. Despite being one of the best studied regions in the world, ...
Resource selection by black-footed ferrets in relation to the spatial distribution of prairie dogs
(University of Missouri--Columbia, 2007)
Once extinct in the wild, the black-footed ferret (Mustela nigripes) is one of the rarest mammals in North America. Reintroductions of ferrets at 13 sites over 10 years have resulted in only 3 self-sustaining populations. ...
The sublethal effects of methoxyfenozide on the field orientation and courtship behavior of Cydia pomonella (Linnaeus) (Lepidoptera: tortricidae)
(University of Missouri--Columbia, 2008)
The sublethal effects of ecdysone agonist methoxyfenozide on the mating behavior and field orientation of codling moth, Cydia pomonella (Linnaeus), was examined. Five different lure types were placed in the upper canopy ...
Insight and executive function: investigating the role of dynamic assessment
(2013)
The aim of this dissertation was to investigate the relationship among clinical insight,

standard format. Thirty-six participants with ...
A Quack on Trial: Advertising and Education in Missouri's Medical Marketplace, 1850--1890
(2014-09-30)
This study compares the lives and practices of Dr. Galen Bishop (1824-1902) and Dr. George Catlett (1828-1886), physicians emblematic of a larger struggle to shape the future of medical practice in America. The orthodox ...
Hydrodynamic characteristics and capillary-assisted heat transfer enhancement of non-condensing/condensing two-phase flows
(University of Missouri--Columbia, 2020)
Interfacial characteristics of two-phase flows were studied through visualization experiments and numerical simulation using computational fluid dynamics (CFD) based on the volume-of-fluid (VOF)-continuum surface force (CSF) method...
Effects of temperature, photoperiod, and substrate on the maturation and reproductive behavior of the Topeka shiner (Notropis topeka)
(University of Missouri--Columbia, 2008)
The Topeka shiner (Notropis topeka) is a federally-listed endangered cyprinid species native to small headwater prairie streams in the mid-west of the United States. It generally spawns over and around sunfish (Lepomis ...
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...
Constraining the slip rate of the Owl Lake Fault by using LiDAR data and fault scarp degradation models
(University of Missouri--Columbia, 2022)
interval. Neotectonic investigations allowed to constrain the slip rate of the Owl Lake Fault as 1.1 - 1.4 mm/yr. The Owl Lake Fault can produce earthquake with the magnitude M=7.2 with the 1030 -- 1430-yr recurrence interval. This study demonstrates...
Top-soil root architecture characteristics of obsolete and modern soybean cultivars and shoot and seed nutrient contents
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Soybean (Glycine max Merr.) is one of the most important cash crops worldwide. It is widely used to produce oil and protein for food and animal feed. Soybean grain...
A shellabration of early life : exploring the taphonomy, diversity, and distribution of small shelly fossils surrounding archaeocyathid reef systems in the Harkless System, Death Valley, NV
(University of Missouri--Columbia, 2023)
poorly preserved; however, µCT volume imaging confirms that external morphological features are insufficient alone to differentiate species from other similar coniform fossils. The second study investigates changes in SSF richness and diversity...

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...
