Investigation of the rest period of seeds
(University of Missouri--Columbia, 1913)
In all plants, including fungi and algae, as well as higher forms, this periodicity of growth, due to season, nutrition, environment, etc., is seen. Practically all temperate zone plants exhibit a yearly periodicity. The ...
A feedlot beef cattle production function study with an economic analysis of corn-silage rations
(University of Missouri--Columbia, 1971)
or the psychology of the individual as a consumer is available on the other hand. The idea contained in the statement above applies to the bundle of economic problems--micro and macro--that economists encounter. This research project is concerned with a...
Three essays on phosphorus runoff and water quality
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Water pollution caused by nutrients, and the resulting eutrophication, have increased over time. This water pollution is increasingly caused by non-point source pollution, both...
Determinants of Beef and Pork Brand Equity
(2003-11)
A set of consumer-level characteristic demand models were estimated to determine the level of brand equity for pork and beef meat cuts. Results indicate that brand premiums and discounts vary by private, national, and store ...
Impact study of a steel I-beam highway bridge
(University of Missouri--Columbia, 1964)
Predator-prey interactions involving the soybean aphid (Hemiptera: Aphididae) in Missouri
(University of Missouri--Columbia, 2007)
The recently introduced soybean aphid, Aphis glycines Matsumura, is found in all soybean growing areas within Missouri. Despite soybean aphid's widespread distribution, it has reached economic threshold in few soybean fields in Missouri. We...
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...
Turning up the heat: fire ecology and climate adaptive silviculture in longleaf pine forests
(University of Missouri--Columbia, 2022)
. While research has shown that this regeneration within patches alters fuel composition, specific changes of fuel loads, and subsequent alterations of fire behaviour and fire effect is unknown. Results indicate that patches reduce fuel loads and fire...
Effects of dormant season soil flooding and soil temperature on pin oak (Quercus palustris) seedlings
(University of Missouri--Columbia, 2022)
. During soil flooding, root mass was significantly less in flooded seedlings than those that were not flooded. However, following drainage this difference was no longer present. By the end of the experiment, seedlings that received flooding exhibited...
An evaluation of pre- and post-timber harvest water quality in low-order streams in the Missouri Ozarks
(University of Missouri--Columbia, 2009)
-and post-harvest samples showed that six of the twelve water quality parameters (TSS, TVSS, Ca, K, NO[superscript 3 -] and SRP) had probabilities that the post-harvest concentration would exceed the pre-harvest concentration, after taking climatic factors...
Regeneration of soil microbial, physical, and chemical properties in restored bottomland hardwood forest wetlands
(University of Missouri--Columbia, 2023)
agricultural practices. SWA had significantly lower values than the other habitat types. Aggregate stability was lowest in the Regeneration (28 percent) and highest in the Reference (46 percent) habitats. The restored habitats had the lowest total carbon (~1...
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...
The impact analysis of structural change in Korean agriculture with respect to the Korean-United States free trade agreement : dynamic simultaneous equation model approach
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The main objective of this study is the analysis of the impacts of the Korean-United States Free Trade Agreement. On April 2, 2007, Korea and the United States concluded a...
Multi-scale factors influencing detection, site occupancy and resource use by foraging bats in the Ozark Highlands of Missouri
(University of Missouri--Columbia, 2007)
Conservation of bat populations requires understanding the associations between bats and their use of resources. We used maximum likelihood to estimate probability of site occupancy using acoustic data for ten species of ...
An ecological study of American Ginseng (Panax quinquefolius L.) in the Missouri Ozark Highlands: effects of herbivory and harvest, ecological characterization and wild simulated cultivation
(University of Missouri--Columbia, 2006)
Matrix population analysis was used to analyze eight years of demographic data from six American ginseng (Panax quinquefolius L.) populations in east-central Missouri to examine effects of herbivory by white-tailed deer (Odocoileus virginianus Zimm...
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...
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...
