Assessing red wolf conservation based on analyses of habitat suitability and human perception of carnivores
(University of Missouri--Columbia, 2018)The red wolf (Canis rufus) is a critically endangered species endemic to the southeastern United States. Currently the world's only wild population resides in a single locale on the Albemarle Peninsula in northeastern North ... -
Birds, bird habitat, and vacant lots in north St. Louis, Missouri
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The neighborhoods of Baden and Wells-Goodfellow have the largest concentration of vacant lots in St. Louis, MO. The Green City Coalition has set forth ... -
Characterization of agroforestry feedstocks and their biochars and their effects on soil greenhouse gas emissions in a floodplain soil
(University of Missouri--Columbia, 2018)The temperature at which biochar (biocharcoal) is produced is a major factor that determines its chemical and structural characteristics. The objectives of this research were to assess the effects of feedstock source among ... -
Characterizing hormesis and the in vitro effects of sub-lethal fungicide exposure in sclerotinia homoeocarpa
(University of Missouri--Columbia, 2018)Dollar spot, caused by Sclerotinia homoeocarpa F.T. Bennett, is the most economically important disease of turfgrass. Dollar spot reduces aesthetics and playability of turfgrass, and when left uncontrolled can result in ... -
Clothianidin decomposition in Missouri wetland soils
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Neonicotinoids are a class of pesticides that have been prevalently used in agriculture since the 1990s. Globally, most neonicotinoid application ... -
Determining electrofishing response thresholds of smallmouth bass (micropterus dolomieu), flathead catfish (pylodictus olivaris), and blue catfish (ictalurus furcatus)
(University of Missouri--Columbia, 2018)We examined the response to electrofishing of three Missouri sportfish: Smallmouth Bass, Blue Catfish, and Flathead Catfish. We had three objectives for this research effort: 1) determine the effective conductivity of each ... -
ENSO and PDO-related variability in South Pacific circulation patterns and seasonal range prediction for Bolivia in South America
(University of Missouri--Columbia, 2018)Seasonal range prediction over North America has been based on intraseasonal and interannual variability related to the Pacific North America (PNA) pattern and El Nino and Southern Oscillation (ENSO), respectively. These ... -
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 ... -
An exploration of mechanisms for Arabidopsis TCP transcription factor activity at an interface of development and immunity
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] "The work presented in this dissertation aimed to characterize new functions and regulatory targets for TCP8, potentially in both defense and development ... -
Heterogeneity in body condition, survival, and seasonal origins among lesser snow and Ross's geese
(University of Missouri--Columbia, 2018)Individual heterogeneity in fitness within a population is well established and provides the required variability for natural selection to take place. Yet, in the case of overabundant midcontinent lesser snow (Anser ... -
The influence of fusarium species on sweet potato plant performance, root yield and quality
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Sweet potato (Ipomoea batatas (L.) Lam.) is a global important food crop, that has recorded an increase in the consumption, and demand for especially ... -
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. ... -
Iron homeostasis is hierarchically regulated by multiple inputs : evidence for the role of reactive oxygen species and iron-zinc cross talk
(University of Missouri--Columbia, 2018)Iron (Fe) is a heavy metal micronutrient vital for all forms of life. In plants, Fe deficiency results in chlorosis and reduced growth, while Fe excess results in lipid peroxidation through the generation of reactive oxygen ... -
Molecular genetic analysis of DRO1 genes in soybean
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Under drought conditions, a strong and deep root system provides advantages for exploring and exploiting moisture in deeper soil layers where water is ... -
