Spatiotemporal variation in Lake Sturgeon movement and habitat selection in Missouri river tributaries : implications for the management and recovery of populations at range margins
(University of Missouri--Columbia, 2021)
Lake Sturgeon were nearly extirpated from Missouri by the 1970s leading the Missouri Department of Conservation (MDC) to list the species as endangered within the state. Recovery efforts commenced with the publication of the first edition...
Great Lakes lake trout early mortality syndrome (EMS) : contaminants, thiamin status, and their possible interaction
(University of Missouri--Columbia, 2006)
Salmonid populations in the Great Lakes experienced a decline in the early twentieth century, presumably due to over-fishing combined with the introduction of exotic parasites such as the sea lamprey. Despite intensive ...
Multi-scale factors influencing detection, site occupancy and resource use by foraging bats in the Ozark Highlands of Missouri
(University of Missouri--Columbia, 2007)
Conservation of bat populations requires understanding the associations between bats and their use of resources. We used maximum likelihood to estimate probability of site occupancy using acoustic data for ten species of ...
Relationship of habitat variables and observation data on muskrat occupancy in an urban green space waterway : a case study from Forest Park, St. Louis, USA
(University of Missouri--Columbia, 2023)
Urban green spaces (UGS) are high value areas that strive to serve both ecological and social goals. Quality stewardship of these areas require that all components affecting the ultimate site goals be addressed in not only ...
Characterization of diverse soybean genotypes for phosphorus uptake and use efficiency
(University of Missouri--Columbia, 2021)
was aimed at identifying and characterizing soybean genotypes which contrast in their ability to take up P and in their PUE. Results from pot and field experiments with diverse soybean genotypes, including SoyNAM parents, obsolete cultivars, commercial...

(University of Missouri--Columbia, 2008)
The rapid rise of St. Louis from eighteenth-century frontier outpost to turn of the century metropolis was due in no small part to its German community. During the middle of the nineteenth century tens of thousands of ...
The influence of body mass and body composition on bone functional adaptation
(University of Missouri--Columbia, 2023)
The proposed dissertation follows a three article format. The articles are distinct, but each pertains to the same subject of research. The first article applies structural equation modeling to factors influencing bone ...
Investigations of Mississippi valley-type mineralizing fluids via analytical geochemistry, numerical modeling, and experimental geochemistry
(University of Missouri--Columbia, 2021)
-stage mineral in MVT deposits, thus it has a high potential for this purpose. However, experimental distribution coefficients (D) for the partitioning of Zn between dolomite and aqueous solution are unknown. A series of dolomite precipitation experiments...
Knickerbockers west : how three playwrights shaped the image of the American west
(University of Missouri--Columbia, 2009)
The American West has remained a compelling force in films, literature and the modern stage, but little research has been directed towards the emergence of the West on the early American stage. The three earliest plays to ...

After President Polk’s announcement in December 1848 of the gold discovery in
California, thousands flocked to the region. Lured by the ready market of potential
customers, daguerreotypists also made their way. The ...
Use of main channel and shallow-water habitat by larval fishes in the lower Missouri River
(University of Missouri--Columbia, 2006)
I developed a series of research objectives organized in a spatial hierarchy to characterize larval fish nursery habitat within the lower Missouri River. Native carpsucker spp./buffalo spp. (Carpiodes spp./Ictiobus spp.) and chub spp. (Macrhybopsis...
