(University of Missouri--Columbia, 2005)
who enrolled in Pre-Calculus courses a at doctoral/research-extensive university. It verified quantitatively that the presence of animated agents with verbal audio in WBI can improve students' mathematics achievement and attitudes toward mathematics...
Integrating cover crops into crop rotations in upstate Missouri
(University of Missouri--Columbia, 2018)
"There is an increasing emphasis on management strategies such as reduced tillage, use of cover crops, and implementation of conservation practices (i.e. terraces, no-till, and cropping systems) in Missouri cropping systems. By combining best...
Cover crop effects on soil moisture dynamics & thermal properties
(University of Missouri--Columbia, 2021)
properties of a corn (Zea mays L.) cropping system. The study was conducted at the Elsberry Plant Material Center - USDA, Missouri, USA, with 1) no-till cover crop (NC), 2) conventional till no cover crop (CN), and 3) no-till no cover crop (NN) treatments. A...
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)
and development of an UGS but also in the day to day management of the area. My research was prompted by park stewards looking for a non-lethal method in which to manage an ever-growing muskrat population. To address this topic, my research established twenty...
Evaluation and development of first order fire effects mortality model predictions for eastern hardwood forests
(University of Missouri--Columbia, 2018)
The First Order Fire Effects Model (FOFEM) is a useful tool for predicting fire-induced mortality in western coniferous forests. However, it lacks robust models for eastern hardwood species. Managers in the eastern United ...
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 ...

(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...
An economic analysis of the agricultural development potential for Southern Honduras
(University of Missouri--Columbia, 1975)
for various resources r which would provide guidance for making investment decisions; and (3) to derive policy recommendations for the purpose of agricultural development in Southern Honduras. A survey of 449 randomly selected sample farms, including 686...
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...

Salvador Island, The Bahamas over the last 3,500 ...
The demography of Atlantic brant (Branta bernicla hrota)
(University of Missouri--Columbia, 2022)
for greatest understanding of population level processes and to inform prioritization of conservation efforts for Atlantic brant. Future brant research should focus on nutrient dynamics of James Bay staging areas, identifying core breeding areas and quantifying...
Yeast mutants containing elevated methionine
(University of Missouri--Columbia, 1983)
Yeasts are deficient in methionine which restricts the nutritive value of the protein. The objective of this research was to produce a methionine-rich mutant. Mutants of Candida tropical is ATCC 1369, Candida tropica!is ATCC 9968, Candida util...
