(University of Missouri-Columbia, College of Agriculture, Agricultural Experiment Station, 1978)
Career development events as a predictor of fall-to-fall retention of first-year college students
(University of Missouri--Columbia, 2020)
examined whether participation and performance in agricultural education CDEs in high school can predict retention of first-year, first-time, full-time college students enrolled in agricultural sciences at a regional, Midwest, public university...
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...
Agroforestry buffer, biomass crop, and grain crop effects on soil quality and soil water use
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Soil degradation, impaired water quality, and reduced soil organic carbon have become major concerns in the management of degraded claypan soils with their associated ecological...
An assessment of the light and nutrient regimes constraining phytoplankton dynamics in Missouri reservoirs
(University of Missouri--Columbia, 2021)
Worldwide, nutrient pollution, or eutrophication, is one of the most pervasive environmental issues threatening water quality. Anthropogenic influences, primarily urbanization and agriculture, have drastically increased inputs of bioavailable...
Roles of dynamin-related protein network in plant immune responses and development
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] At the host-pathogen interphase, the PM's protein composition has a critical role in how plants perceive and respond to the invading pathogenic attacks. However...
Influence of various wetting agents on water status in USGA greens as determined by their physical properties
(University of Missouri--Columbia, 2021)
Soil hydrophobicity is an increasing issue in sandy soils, affecting agricultural land and golf courses. This phenomenon causes water repellency and bypassing of hydrophobic root zones, limiting water accessibility. Due to golf course putting greens...
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...
Interactions between neuroanatomy, cognition, and ecology in Anolis lizards
(University of Missouri--Columbia, 2021)
, such as in dispersal to islands, biotic invasions, and urban adaptation. Cognitive specializations may also be associated with specific ecological traits, such as habitat complexity. Furthermore, our understanding of the neural substrates of cognition in the brain...
Assessing costs and environmental impacts of municipal food waste treatment options in Columbia, Missouri : a decision support tool integrating life cycle analysis and robust optimization
(University of Missouri--Columbia, 2021)
and targets, decisionmakers need data-driven analysis to understand both the costs and environmental impacts of their plans. This study develops a decision support tool applied in Columbia, Missouri, USA, with aims to model the economic and environmental...
Implications of ovarian and uterine maturity evaluated in replacement heifer candidates
(University of Missouri--Columbia, 2021)
days after the end of the breeding season. The incidence of disparate ovarian score (OS) and uterine score (US) was 33.7 percent (n = 158/469) in Experiment 1 and 16.3 percent (n = 3,622/22,174) in Experiment 2. Heifers assigned a RTS of less than 3-3...
Phytoplankton response to water quality threats in Midwest reservoirs
(University of Missouri--Columbia, 2021)
Harmful cyanobacterial blooms and invasive species threaten water quality. These threats are expected to worsen in the future, emphasizing the need for creative management solutions and a thorough understanding of their ...
Monitoring of an urban level spreader as part of the collaborative adaptive management process
(University of Missouri--Columbia, 2020)
Irregular flows, such as the high flows caused by stormwater runoff after a rain event are a major cause of stream impairment in urbanized watersheds. The Hinkson Creek CAM (Collaborative Adaptive Management) approach is ...
Efficient closed-form estimators in multistatic target localization and motion analysis
(University of Missouri--Columbia, 2021)
an object location estimator. Two measurements are sufficient in 2-D and three in 3-D to yield a solution if they are consistent. The derived minimum measurement solution is exact and reduces the computation to the roots of a quadratic equation. The solution...
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...
Investigation of the initial steps of jasmonic acid biosynthesis and a study of differential regulation of the ribosomal association of mRNA transcripts in jasmonate-dependent wound response
(University of Missouri--Columbia, 2020)
in both wildtype (WT) and a mutant defective in JA-dependent wound response in Arabidopsis. Previous research indicated some wound-responsive JA marker proteins were less abundant in the mutant, b1b3, after wounding although their respective transcripts...
Spatiotemporal variation in Lake Sturgeon movement and habitat selection in Missouri river tributaries : implications for the management and recovery of populations at range margins
(University of Missouri--Columbia, 2021)
over 3.5 years and 187 age-0 juvenile Lake Sturgeon during the fall/winter of two years. Missouri River tributaries were important habitats for adult and subadult Lake Sturgeon throughout the year. Lake Sturgeon use of the Osage River was greater in all...
The Impact of Climate Variability and Land Cover Change on Groundwater Resources in The Niger River Basin
(2021)
from 2001-2013, the precipitation increased during the dry season by about 3%, but no significant change was observed during the wet season. The change in the LULC increased substantially in the areas dominated by agriculture, forests, and shrubs...
