Diversity and evolution of the sauropsid trigeminal sensory system
(University of Missouri--Columbia, 2022)
Understanding the evolution of sensory perception is essential in explaining organismal behavior. Organisms using environmental stimuli to navigate their environments, avoid predation, capture prey, and find a mate, have ...
Utilizing unoccupied aerial systems and artificial intelligence for monitoring nonbreeding waterfowl abundance in Missouri
(University of Missouri--Columbia, 2023)
aerial survey techniques that are less disturbing to waterfowl, but there is limited information on how waterfowl in winter respond to UAS. Therefore, we compared the behavioral responses of waterfowl to helicopters and UAS on Missouri Department...
Irrigation practices and costs in southeastern Missouri - 1959
(University of Missouri--Columbia, 1961)
Field crop irrigation is a relatively new production technique in Missouri. Prior to this investigation, only United information was available concerning costs and returns. The research reported here was assigned to determine (1) the costs...
Highway impacts on Ozark incomes and employment
(University of Missouri--Columbia, 1970)
Introduction and problem review: Confronted by depressed economic and social conditions of extensive regions within the United States, the Federal Government through its various agencies is waging "war on poverty." Many ...
On the ability of rocks to conduct heat in the Lithosphere
(University of Missouri--Columbia, 2019)
This work focuses on creating a model for the conductive thermal transport properties of rocks using measured thermal diffusivity (D) with the Laser Flash Analysis (LFA) method, which eliminates common errors associated ...
Biogeochemistry and inorganic geochemistry as indicators of the paleoenvironment and paleohydrology of the Al-Azraq Basin, Jordan
(2013)
This study investigates the biogeochemical and inorganic geochemical
indicators for past environments and paleohydrology of a high resolution sediment record
from the Al-Azraq Basin, Jordan. The second largest basin in ...
Quantifying neonicotinoid concentrations in Missouri wetlands, their driving factors, and the potential effects on the reliant avian community
(University of Missouri--Columbia, 2018)
Neonicotinoid insecticides became available for commercial use in North America in the late 20th Century. Since their introduction, studies of surface waters where neonicotinoids are available for use have measured neonicotinoid concentrations...
Methods for high-resolution soil-landscape modeling in midwest upland landscapes
(University of Missouri--Columbia, 2008)
. These methods were tested in the upland landscapes of northern Missouri. Sensors, especially DRS, successfully estimated profile clay and organic carbon. Peak functions were valuable for modeling profile clay content and covariates of clay. Coherent depth...
Effects of temperature, photoperiod, and substrate on the maturation and reproductive behavior of the Topeka shiner (Notropis topeka)
(University of Missouri--Columbia, 2008)
The Topeka shiner (Notropis topeka) is a federally-listed endangered cyprinid species native to small headwater prairie streams in the mid-west of the United States. It generally spawns over and around sunfish (Lepomis ...
The relative impact of principal managerial, instructional, and transformational leadership on student achievement in Missouri middle level schools
(University of Missouri--Columbia, 2007)
of a larger study of middle level education being conducted by the Middle Level Leadership Center at the University of Missouri-Columbia. Two survey forms were used to collect data for this study. One survey collected data on managerial...
Neurochemical, epigenetic, and structural brain changes associated with prenatal stress exposure, and the mitigating effects of DHA
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 5/1/2024] The Developmental Origins of Health and Disease (DOHaD) hypothesis posits that in utero stress exposure can modify developmental trajectories, influencing adult health. Research indicates that ...
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...
Effects of prescribed burning in Missouri Ozark upland forests
(University of Missouri--Columbia, 2007)
Prescribed fire is used in Missouri to achieve various silvicultural goals, but the use of burning in upland Ozark forests raises many questions that research has yet to answer. The purpose of this study is to examine the effects of prescribed...
Flow and heat transfer properties of Mono Craters rhyolites : effects of temperature, water content, and crystallinity
(University of Missouri--Columbia, 2008)
The nature of volcanic processes, including rate of magma ascent, exsolution of volatiles, eruption style, and flow distance, is highly dependent on the viscosity of the associated magma and its ability to transfer heat. ...

(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This paper analyzes the effect of stock market liberalization and trade liberalization on the relationship between FDI and economic growth using the data of 124 countries...
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...
