Canopy recruitment dynamics in naturally regenerated longleaf pine (pinus palustris) woodlands
(University of Missouri--Columbia, 2017)
. While research has elucidated much about regeneration dynamics, there is a paucity of information regarding the recruitment period between the grass stage and canopy status. The overall goal of this project was to determine the factors influencing canopy...
Analysis of twenty-five years of heavy rainfall events in the Texas Hill Country
(University of Missouri--Columbia, 2008)
climate stations in the region; the period examined for this study was 1982-2006. Days with measurable precipitation were treated as a gamma distribution in order to determine the top 2%, 1%, and 0.5% to define events as unusual, rare, and extreme...
Understanding students' technology appropriation and learning perceptions in online learning environments
(University of Missouri--Columbia, 2005)
Distance education has the unique characteristic of using technologies as the primary means of delivery of instruction and interaction. The present study contributes to research dedicated to explaining or predicting phenomena related to distance...
Effects of dormant season soil flooding and soil temperature on pin oak (Quercus palustris) seedlings
(University of Missouri--Columbia, 2022)
. During soil flooding, root mass was significantly less in flooded seedlings than those that were not flooded. However, following drainage this difference was no longer present. By the end of the experiment, seedlings that received flooding exhibited...
A quarterly econometric model of the United States beef sector
(University of Missouri--Columbia, 1982)
The United States beef sector has been modeled in many studies, perhaps, because beef represents a large proportion of the consumer food dollar and agriculture’s income. The predictive performance of these models has been, however, quite...
Designing a LANDIS PRO harvest module and examining the effects of temporal resolution on simulation outcomes
(University of Missouri--Columbia, 2012)
The development and testing of forest landscape models is an ongoing process. This thesis documents a portion of this process working with the LANDIS PRO 7.0 forest landscape model in two parts. In the first chapter I ...
Polyacrylamide amendment for erosion and runoff control on soils of differing characteristics
(University of Missouri--Columbia, 2009)
The use of anionic polyacrylamide (PAM) as a soil amendment is an emerging conservation practice. However, guidelines have not been developed with considerations of soil properties and topographic characteristics. The ...
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...
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 functional morphology...
Evolution of the Bahamian coastal environment of San Salvador Island over the last 3,500 years based on triangle pond sediment cores
(2014-07-25)
The multiproxy examination of ten soft sediment cores extracted from Triangle Pond
was used in order to establish alterations in the northwestern coastal environment of San
Salvador Island, The Bahamas over the last 3,500 ...
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...
Elemental concentration changes in soil and stockpiled tall fescue leaves after liming
(University of Missouri--Columbia, 2006)
of stockpiled tall fescue. Others have predicted that liming will increase P and decrease aluminum (Al) availability to plants in the types of soils used in this study. Study sites were located at the University of Missouri's Southwest Center (SWC) and Bradford...
Regeneration of soil microbial, physical, and chemical properties in restored bottomland hardwood forest wetlands
(University of Missouri--Columbia, 2023)
(WRP)] was initiated with the goal of reducing the loss of wetlands and restoring wetlands previously converted to agricultural land use. Despite the importance of preserving and restoring wetlands, the benefits of wetland restoration have not been well...
Adsorption of fluorescent labeled E. coli in selected vegetative buffer systems
(University of Missouri--Columbia, 2022)
cases, the first landing zone for pathogens is soil, from which they transport into the water. Increasing global industrialization and polluting soil with contaminants from both agricultural processes and industrial waste products has caused several life...
Ambrosia beetle habitat use, host use, and influence on early wood colonizing microbes in an oak-hickory forest
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Knowledge of how exotic ambrosia beetles influence microbe communities and how forest characteristics affect ambrosia beetle abundance will improve policy and management...
An evaluation of pre- and post-timber harvest water quality in low-order streams in the Missouri Ozarks
(University of Missouri--Columbia, 2009)
Missouri Department of Conservation's (MDC) best management practices (BMPs) for Regenerative Oak Clear Cutting (ROCC) practice was evaluated on effectiveness to preserve downstream water quality. Fifteen sites, located on MDC lands in Shannon...
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...
