The survival and growth of shortleaf pine systems in the Missouri Ozarks : effects of competition, genetics, and site preparation
(University of Missouri--Columbia, 2019)
survival and growth rates of planted shortleaf pine relative to artificial and natural hardwoods, identify barriers to regeneration success, and develop tools for individual tree assessment. Data from three long-term studies in southeastern Missouri were...
Effect of irrigation on fertilizer nitrogen requirement, economic returns, and water availability in a corn-soybean rotation
(University of Missouri--Columbia, 2019)
application. Two irrigation experiments were conducted at University of Missouri Greenley Research Center near Novelty, MO from 2015 to 2018. In each experiment, three irrigation treatments: sprinkler irrigation, subsurface drip irrigation, and no...
Data-Driven Modeling of the Lake Chad Basin Hydrologic Systems
(University of Missouri -- Kansas City, 2019)
The drying of the Lake, located in Central Africa, is one example of a water crisis,
which requires more research and studies. The lake has been progressively shrinking since the
1960s due to climate change and anthropogenic ...
A partial equilibrium model of Afghanistan wheat market
(University of Missouri--Columbia, 2019)
This study focuses on the construction of a structural economic model for the wheat market in Afghanistan. We create two models with alternative approaches to model closure, one based on a price linkage approach and the ...
Three essays on agglomeration, strategic orientation, and organizational form
(University of Missouri--Columbia, 2019)
This dissertation consists of three essays, trying to fill a gap in the literature by exploring the interaction of agglomeration, ownership structure, and strategic orientation. Much research has been focused on each ...
Looking broadly and deeply into perspectives of local climate change impacts among visitors to Missouri state parks
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Missouri's outdoor recreation resources provide numerous mental, physical, and social values to millions of people each year and serve as a major contributor to the statewide...
The distribution of financial responsibility within the family and its effect on family risk behaviors
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Men are more willing to take risks and invest more in stocks than women. Do gender differences with respect to risk tolerance still exist within married and cohabiting couples...
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...
