Allelopathic effects and removal of overseeded ryegrass on bermudagrass
(University of Missouri--Columbia, 2010)
is essential for bermudagrass recovery or decline of bermudagrass is inevitable. However, underlying reasons for this decline is unknown. Objectives of this research were to assess allelopathic effects of ryegrasses on bermudagrass and determine best management...
Impacts of Precipitation, Land use Land cover and Soil type on the Water Balance of Lake Chad Basin
(2013)
the runoff from the agricultural land. The annual mean interception in LCB for the period 2003 - 2010 ranges from 0 - 63 mm with the mixed forest intercepting more water than open vegetation such as grass and shrub. Also the annual mean actual...
Winter bird densities and eastern wood-pewee breeding demography across a savanna-woodland-forest gradient in the Missouri Ozarks
(University of Missouri--Columbia, 2012)
and woodland is needed to inform management. Our objective was to determine densities of common winter migrants and resident birds in savannas, woodlands, and non-managed forests in the Missouri Ozark Highlands. We estimated detection probabilities...
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...
Pre-harvest water quality of ephemeral streams in Missouri Ozark forests
(University of Missouri--Columbia, 2006)
The Missouri Department of Conservation (MDC) developed a best management practice that leaves a riparian buffer next to streams to reduce the possibility of water quality degradation. The purpose of this study is to quantify water quality in upland...
Effects of amending a gravel based growing medium with calcined clay on medium physical properties and growth of Gymnocladus dioicus seedlings
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Missouri Gravel Bed (MGB) is a system that uses pea gravel with 10% sand (v/v) as a root growth medium, allowing bare root plants to be removed from the gravel and planted...
Elephant in the room : a study of the impact of emotional experiences on burnout among Chinese reporters
(University of Missouri--Columbia, 2020)
and reporters' experience of engaging in surface acting magnify their levels of job burnout. Meanwhile, the use of problem-focused coping strategies can reduce reporters' job burnout caused by emotional labor engagement. Findings in this study fill the gap...
Habitat use and home range of American bitterns (Botuarus lentiginosus) and monitoring of inconspicuous marsh birds in northwest Minnesota
(University of Missouri--Columbia, 2007)
), Pied-billed Grebes (Podilymbus podiceps), Soras (Porzana carolina), and Virginia Rails (Rallus limicola)) is needed to inform conservation and management actions. My research, from 1999 - 2002, examined breeding habitat use and home range of American...
Detection and modeling of bat species occupancy at multiple scales across a forested landscape in southeastern Missouri
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Populations of forest dwelling bats have been in decline in recent years, and have therefore become increasing foci in forestry research efforts. Difficulty in bat species...
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...
Simulating cottonwood tree growth in flood plains using the LIGNUM modeling method
(University of Missouri--Columbia, 2006)
simulation model, was applied to simulation of the cottonwood growth in a flood plain area in central Missouri. The key characteristics of the LIGNUM model are the linkage between tree spatial structure and physiological function. L-system was adopted...
Fertilizer effects on soil pH, soil nutrients, and nutrient uptake in swamp white and pin oak seedlings on an alkaline Missouri River bottomland
(University of Missouri--Columbia, 2008)
There is growing interest among forest and wildlife managers in the reforestation of bottomlands with mast producing hardwoods in the Lower Missouri River and Mississippi River Alluvial valleys. However, it is common for bottomland hardwood...
Forest pest control : commercial pesticide applicator training (2011)

A Python-based GIS simulation of a water balance for wetland decision-making
(University of Missouri--Columbia, 2021)
wetland site to determine the potential existence of the excess water component. The study area is a location within Pershing State Park within Linn County, Missouri. Three goals have been set in this research in order to achieve the ultimate goal...
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...
Rheological and morphological evolution of basaltic lava flows
(University of Missouri--Columbia, 2018)
the following research questions: (1) How does the rheology of active flows evolve during emplacement; and (2) How can we use flow morphology to infer the rheology of inactive flows? ... At Piton de La Fournaise (La R�union, FR DOM), I addressed the longstanding...
Experiences of racialized classism among first-generation and economically-marginalized U.S. college students of color : a critical thematic analysis
(University of Missouri--Columbia, 2023)
"-class status. These forces contribute to their regular exposure to racialized forms of classism. This study investigates how classism is experienced as racialized among first-generation and economically-marginalized (FGEM) university students from these groups...
Macroinvertebrate assemblage composition along a longitudinal multiple-land-use gradient in a midwestern stream
(University of Missouri--Columbia, 2012)
Land use changes often alter hydrogeomorphology and hydrologic flow regimes, which can adversely impact stream aquatic biota. Hinkson Creek Watershed (HCW, 231km2) located in Boone County, central Missouri, is comprised of 50% agriculture, 26...
