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...
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)
over 3.5 years and 187 age-0 juvenile Lake Sturgeon during the fall/winter of two years. Missouri River tributaries were important habitats for adult and subadult Lake Sturgeon throughout the year. Lake Sturgeon use of the Osage River was greater in all...
Phytoplankton response to water quality threats in Midwest reservoirs
(University of Missouri--Columbia, 2021)
Harmful cyanobacterial blooms and invasive species threaten water quality. These threats are expected to worsen in the future, emphasizing the need for creative management solutions and a thorough understanding of their ...
Development and validation of standardized sampling protocols for assessing freshwater mussel populations in Missouri
(University of Missouri--Columbia, 2017)
step in assessing populations. We surveyed 14 sites in the Meramec River Basin in East-central Missouri to determine the effectiveness of visual sampling methods and to determine the effects of habitat variability on the effectiveness of these methods...
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...
Turning up the heat: fire ecology and climate adaptive silviculture in longleaf pine forests
(University of Missouri--Columbia, 2022)
Frequent fire is required to maintain the characteristic structure, function, and high biodiversity of longleaf pine woodlands. Longleaf pine regeneration is exposed to this frequent fire, yet persists as both patches and ...
Agro-pastoral Landuse Transformation: Implications and Perspectives in the Northwest Region of Cameroon
(2015-08-11)
This dissertation centers on the human-environmental problem of agro-pastoral
landuse transformation in Northwest Cameroon, identifying population pressure, climate
change, environmental degradation, land grabbing, change ...
Movement, habitat use, and spawning characteristics of flathead and blue catfish on the lower Missouri River and tributaries
(University of Missouri--Columbia, 2010)
The movement and habitat use patterns of adult flathead and blue catfish were studied via acoustic and radio telemetry in the lower Missouri River and adjacent tributaries including the Grand, Lamine, Chariton, and Little Chariton Rivers...
Creating a zero-waste soy processing system and developing vitamin B12 fortified non-GMO high oleic soy-based products using encapsulation technology
(University of Missouri--Columbia, 2023)
temperature stability factor to our diet due to their high temperature tolerance. In line with sustainability standards, a newly developed variety at the University of Missouri and the USDA (non-GMO-HO soybean). The soybean processing industry generates...
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 ...
Derivation of walk-in cooler and freezer Performance Standard equations as they pertain to the ANSI/AHRI Standard 1250 and 1251
(University of Missouri--Kansas City, 2012)
-in refrigeration units to validate the revised calculation method. Raw results show improved correlation of compressor runtime, because a specific compressor runtime was targeted, reducing variation between hourly simulations and the 1250 calculation from -29...
Forgetting strength : Coffeyville, the black freedom struggle, and the vanishing of memory
(2013)
When a white lynch mob of 3,000 stormed the city jail in Coffeyville, Kansas, in 1927, incited by rumors that three "negroes" had raped two white high school girls, the incident ended very differently from so many others in the Jim Crow era. No one...

The influence of climate and population structure on East Asian skeletal morphological variation
(University of Missouri--Columbia, 2022)
Objectives: Recent studies have shown that global variation in body proportions is more complex than previously thought as some traits formerly associated with climate adaptation are better explained by geographic proximity ...
