Effects of prescribed fire on forest soil properties in the Ozark Highlands
(University of Missouri--Columbia, 2020)
soil bulk density was measured at the 0-10, 10-20, and 20-30 cm depths before fire, and bulk density at the 0-10 cm depth was re-sampled two years post-burn. There was no change in bulk density of the whole soil and the fine soil fraction. Mineral soil...
The role of terrrestrial habitat in the population dynamics and conservation of pond-breeding amphibians
(University of Missouri--Columbia, 2007)
I used both demographic modeling and experimental field research to evaluate the role of terrestrial habitat in the population dynamics and conservation of pond-breeding amphibians. I began by using literature data to ...
Dissipation and carryover of imidazolinone herbicides in imidazolinone-resistant rice (Oryza sativa)
(University of Missouri--Columbia, 2007)
The development of Imidazolinone (IMI) Resistant (IR) rice now allows rice producers to selectively control red rice (Oryza sativa, O. rufipogon, and O.nivara), weedy relatives of commercial rice (O. sativa). Imazethapyr ...
Impacts of municipal wastewater effluent on seed banks, chemistry, and microorganisms of soils excavated from wetland impoundments designated for wildlife
(University of Missouri--Columbia, 2009)
To evaluate the effects of municipal wastewater effluent (WWE) and Missouri River water (MOR) as irrigation sources on soil chemistry, seed banks, and microorganisms, a field study was conducted in conjunction with a set ...
Agroforestry buffer, biomass crop, and grain crop effects on soil quality and soil water use
(University of Missouri--Columbia, 2020)
may avoid soil degradation as well as improve soil and water quality. The objectives of this study were (i) to evaluate the effects of different perennial vegetative management systems and soil depth (10- cm depth increments from the surface to the 40...
Plant community response during establishment of woodland silvopasture in the Missouri Ozarks
(University of Missouri--Columbia, 2022)
forages) on plant community composition and structure during one year of woodland silvopasture establishment in the Missouri Ozarks. Midstory removal (stems [less than or equal to] 25 cm diameter at breast height) significantly increased graminoid...
First quantitative trait loci detected for bearing habit and nut quality traits in eastern black walnut (Juglans nigra L.)
(University of Missouri--Columbia, 2022)
Eastern black walnut (Juglans nigra L.) offers potential as an orchard nut crop throughout the Midwest and eastern parts of the US, where the species has a long history of use by indigenous peoples as food and medicine. ...
Variability of soil hydraulic properties and estimation of plant-available water on claypan-soil landscapes
(University of Missouri--Columbia, 2007)
and landscape position, intact soil core samples (76 by 76 mm) were taken from the 0- to 10-, 10- to 20-, and 20- to 30-cm soil depths. For objective 2, soil profile samples were taken at 18 to 19 locations from each of two close-by fields and PAW capacity...
Macroinvertebrate and crayfish communities in the Meramec River drainage basin: an investigation at multiple spatial scales
(University of Missouri--Columbia, 2006)
Hierarchical classification systems have been widely used to delineate terrestrial ecounits at multiple spatial scales; however there has long been a need for an aquatic based classification system. A newly developed aquatic ...
The role of genetic and phenotypic diversity in maize and its effects on aflatoxin accumulation by the fungus Aspergillus flavus
(University of Missouri--Columbia, 2008)
Accumulation of the potent carcinogen, aflatoxin, in maize poses a significant health risk to humans and animals. Most commercially grown maize lines are susceptible to infection by the fungus that synthesizes aflatoxin, ...
Forage production and diversification for climate-smart tropical and temperate silvopastures
(University of Missouri--Columbia, 2019)
Climate change creates much uncertainty for the future of animal agriculture, particularly due to an increase in summer droughts that result in the loss of range productivity. Silvopasture, the intentional integration of ...

The secret lives of African forest elephants: using genetics, networks, and telemetry to understand sociality
(University of Missouri--Columbia, 2012)
extensive networks of individuals suggesting fission-fusion sociality. Also, adult females at distances of five kilometers or less were more closely related to each other than expected from chance. Known adult females and their associates were tracked...
Alcohol consumption, executive function and risky decision making
(University of Missouri--Columbia, 2009)
Previous research has shown that alcohol intoxication can adversely affect behavior by impairing higher cognitive function (e.g., Giancola, 2000) and can lead to increased risk-taking (Leigh, 1999) via impaired executive ...
Metamorphism of the Wales Group and Moira Group on Prince of Wales and Dall Islands, southeastern Alaska
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This study examines the metamorphic history of the Proterozoic to Early Ordovician Wales Group and the newly-named Ordovician to Silurian Moira Group ...
Specific bio-modeling and analysis techniques at cellular and systems level
(University of Missouri--Columbia, 2006)
focuses on mathematical models at the systems level. Specifically, thermal physiology models of the entire human body are developed using statistical and black box (artificial neural network, ANN) techniques.The MU 2-D Man, a human thermal model has been...
Isotope harvesting from the beam dump cooling loop at the facility for rare isotope beams (FRIB)
(University of Missouri--Columbia, 2018)
Isotope harvesting from the beam dump cooling loop of the Facility for Rare Isotope Beams (FRIB) offers usable quantities of many isotopes unavailable anywhere else in the world. Many of these co-produced isotopes are of ...
