A test of differential GPS correction methods at Fort Huachuca, Arizona
(University of Missouri--Columbia, 2009)
in differential correction has previously proven unreliable. The effectiveness of base data acquired through use of a second field unit as an on-site base station was compared with the use of CORS. The accuracy of data differentially corrected using base data...
Overstory density and its effect on oak regeneration abundance and oak understory height growth in the Missouri Ozark Highlands
(University of Missouri--Columbia, 2008)
This study examined how overstory density affects regeneration abundance and understory height growth in the Missouri Ozark Highlands. Data were collected on three different treatment types, no harvest management, uneven-aged management, and even...
Mizzou weekly, volume 23, number 10 (October 25, 2001)

Stand structure development effects on wood quality of Melina (Gmelina arborea roxb.)
(University of Missouri--Columbia, 2009)
A stem analysis was perform to examines the effects of thinning treatments on Melina (Gmelina arborea) wood quality and tree architecture in the North Coast of Colombia. 27 plots under forest management regimes and age ...
Restoration treatments and regeneration dynamics in East Texas mixed wood forests
(University of Missouri--Columbia, 2023)
Extensive harvesting, fire exclusion, and plantation forestry altered composition and structure, and thus function and habitat values of east Texas Pineywoods uplands. Upland restoration efforts are made difficult by the ...
Latinos in Missouri : the media role in the acculturation process
(University of Missouri--Columbia, 2008)
The influx of Hispanics into the United States is significant and will most likely continue to be important for some time to come. Many immigrate to Missouri and attempt to settle there, to form a home and to integrate themselves into the greater...
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...

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)
to establish a self-sustaining population. In this project we focused on the following research objectives: (1) elucidate the factors that influence movement patterns of Missouri River Lake Sturgeon, (2) investigate survival and dispersal of stocked age-0 Lake...
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...
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...
Effects of prescribed fire and timber harvest on terrestrial salamander abundance, behavior, and microhabitat use
(University of Missouri--Columbia, 2014)
surveys for three years and used a statistical modeling approach that accounted for the tendency of terrestrial salamanders to be belowground and unavailable for surveys. I found that terrestrial salamander density at our Missouri Ozark study site ranged...
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...
Social inequalities and mortality during the 1918 influenza pandemic on the island of Newfoundland
(University of Missouri--Columbia, 2022)
Pandemics are anthropogenic events, and an anthropological perspective can be advantageous for a comprehensive understanding of the impact of the 1918 influenza pandemic. Research on the 1918 influenza pandemic has shown that there are considerable...
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...
Identification and characterization of health-promoting benefits and bioactive molecules in black walnuts (Juglans nigra l.) and waste materials from agroforestry systems
(University of Missouri--Columbia, 2020)
selected and cultivated for nut production by the University of Missouri - Center for Agroforestry (Columbia, MO, USA). Additionally, it is likely that the bioactive activities of black walnut are correlated with its bioactive constituents including...
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 ...
