An analysis of the economic viability of farm credit system banks and combined associations
(University of Missouri--Columbia, 1991)
Restoring forest composition and structure of riparian corridors in the Missouri Ozarks
(University of Missouri--Columbia, 2008)
bottomland agricultural fields. These afforestation practices most often consist of planting bare-root tree seedlings of a select number of hardmast species and managing vegetation with a number of pre- and postemergent herbicides, or planting a perennial...
Effects of riparian buffer width on stream salamander populations in the southern Appalachian Mountains
(University of Missouri--Columbia, 2008)
Salamanders in the Appalachian region have been extensively studied, but the majority of research assessing the impacts of logging has focused on terrestrial species that are not dependent on stream habitats for egg deposition or larval development...
The demography of Atlantic brant (Branta bernicla hrota)
(University of Missouri--Columbia, 2022)
for greatest understanding of population level processes and to inform prioritization of conservation efforts for Atlantic brant. Future brant research should focus on nutrient dynamics of James Bay staging areas, identifying core breeding areas and quantifying...
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...
Drainage water management practices affect water quality, soil properties, and crop production
(University of Missouri--Columbia, 2023)
. This dissertation includes results from four studies conducted at the MU Greenley Research Center, Grace Greeley farm, and Ross Jones farm. Long-term, no-till research evaluated the influence of a wheat (Triticum aestivum L.), radish (Raphanus raphanistrum subsp...
An economic analysis of the agricultural development potential for Southern Honduras
(University of Missouri--Columbia, 1975)
for various resources r which would provide guidance for making investment decisions; and (3) to derive policy recommendations for the purpose of agricultural development in Southern Honduras. A survey of 449 randomly selected sample farms, including 686...
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...
Accrual persistence and accrual anomaly
(University of Missouri--Columbia, 2007)
The first essay, "Inter-temporal accrual persistence and accrual anomaly" investigates whether accrual persistence and accrual anomaly vary with the state of economy. Prior accounting research argues that diminishing marginal returns on new...
Tales of an 'invisible' life stage : survival and physiology among terrestrial juvenile ambystomatid salamanders
(University of Missouri--Columbia, 2019)
of the many amphibian species for which stage-specific data are lacking. Next, I reared larvae of five species (A. annulatum, A. maculatum, A. opacum, A. talpoideum, and A. texanum) from populations along an ~200 km latitudinal gradient in Missouri, USA...
Nutrients, chlorophyll and bacterial fecal indicators in coves and open water areas of Lake of the Ozarks, Missouri
(University of Missouri--Columbia, 2009)
Urban development and use of septic tanks in porous soils of Lake of the Ozarks poses a threat to public health via leaching into drinking wells and coves used for swimming. During 2 summers, phosphorus (TP), nitrogen (TN), ...
Body size and shape in insular environments and applications of the island rule in biological anthropology
(University of Missouri--Columbia, 2021)
The discovery of small-bodied hominin fossils in 2004 on the island of Flores, Indonesia, unearthed a large debate within biological anthropology. This debate has exemplified that there are questions and research areas that biological...
Evolution of the Bahamian coastal environment of San Salvador Island over the last 3,500 years based on triangle pond sediment cores
(2014-07-25)
The multiproxy examination of ten soft sediment cores extracted from Triangle Pond
was used in order to establish alterations in the northwestern coastal environment of San
Salvador Island, The Bahamas over the last 3,500 ...
Development and validation of standardized sampling protocols for assessing freshwater mussel populations in Missouri
(University of Missouri--Columbia, 2017)
step in assessing populations. We surveyed 14 sites in the Meramec River Basin in East-central Missouri to determine the effectiveness of visual sampling methods and to determine the effects of habitat variability on the effectiveness of these methods...
