Photosynthesis and heat tolerance of soybean
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Photochemical Reflectance Index (PRI) is determined from canopy spectral reflectance measurements and can provide important information about photosynthesis. The PRI can...
Development and application of vegetative buffer width modeling using geographic information systems
(University of Missouri--Columbia, 2009)
of performance could potentially require wider or narrower buffer widths in order to meet certain stormwater management criteria. This method was successfully demonstrated within the LaBarque Creek watershed located southwest of St. Louis, Missouri for three...
Motives for savings and portfolio choice : evidence from micro-data for Japan
(University of Missouri--Columbia, 2006)
This study investigates the effects of income risk and liquidity constraints on household portfolio choice and saving behavior using Japanese household-level data (POSFAL) from 1989 to 2003. An integrated analysis for three ...
Ambrosia beetle habitat use, host use, and influence on early wood colonizing microbes in an oak-hickory forest
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Knowledge of how exotic ambrosia beetles influence microbe communities and how forest characteristics affect ambrosia beetle abundance will improve policy and management...
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 ...
Simulating prehistoric population dynamics and adaptive behavioral responses to the environment in Long House Valley and Black Mesa, Arizona
(University of Missouri--Columbia, 2018)
produce unexpected results, including those that deviate from the population patterns observed archaeologically. Despite these unexpected interactions, the results support the importance of variations in agricultural productivity in driving human...
Resource selection, movement patterns, and survival of post-fledging grassland birds in Missouri
(University of Missouri--Columbia, 2005)
meadowlarks (Sturnella magna) in southwestern Missouri, from 2002 to 2004 using radio telemetry. Across species at the micro-scale, there was support for the predation hypothesis (both species) and the thermal refuge hypothesis (dickcissels only). Woody cover...
A quarterly econometric model of the United States beef sector
(University of Missouri--Columbia, 1982)
The United States beef sector has been modeled in many studies, perhaps, because beef represents a large proportion of the consumer food dollar and agriculture’s income. The predictive performance of these models has been, however, quite...
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...
Impact of alternate host phenology amd alternate hose-transgenic corn interactions on the Western corn rootworm (Coleoptera: Chrysomelidae)
(University of Missouri--Columbia, 2006)
With the increasing adoption of transgenic maize with resistance to rootworms, combined with glyphosate tolerance, as a control tactic for western corn rootworm, Diabrotica virgifera virgifera LeConte, an understanding of ...
Woody species and forest structure in northern Missouri riparian forests with different ages and watershed sites
(University of Missouri--Columbia, 2006)
A chronosequence (1 to 250+ years) of 160 woody species plots was established throughout northern Missouri riparian forests to explain the influence of site hydrology and stand age on species distribution and forest structure. Stand age was found...
Hydraulic Characterization of Interlocking Concrete Permeable Pavement
(2015-08-12)
The environmental benefits of permeable pavements are vast and include stormwater
quantity reduction, stormwater quality improvement, urban heat island mitigation, and
groundwater recharge, among others. Permeable ...
Agent-based modeling of the spread of the 1918-1919 Spanish Flu in three Canadian fur trading communities
(University of Missouri--Columbia, 2006)
In this project, an agent-based computer simulation was developed to model the spread of the 1918-1919 influenza pandemic within and among three Aboriginal communities in central Manitoba. Data from model simulations ...
Genetic and nutritional effects on reproduction in lactating dairy cows
(University of Missouri--Columbia, 2020)
Good reproductive performance is a prerequisite for profitable pasture-based seasonal calving systems of milk production. The objective of this dissertation was to elucidate the physiological mechanisms contributing to ...
Fluctuating asymmetry as a measure of developmental instability in Arikara bioarchaeological assemblages
(University of Missouri--Columbia, 2018)
from skeletal assemblages excavated from numerous Arikara archaeological sites along the Missouri River in South Dakota. These assemblages were selected for this study because they represent a single, culturally and genetically affiliated population...
Evaluation of Cement-Based Reactive Media for Contaminant Remediation
(University of Missouri -- Kansas City, 2018)
Water contaminated with heavy metals, arsenic, and other industrial pollutants
poses a severe risk to human health. Reactive media present an opportunity to intercept
contaminants but have high material or environmental ...
Neighborhood effects, convergence and growth in open economies of U.S. and Mexico
(University of Missouri--Columbia, 2007)
differentials. I used a logit model to estimate whether or not Missouri cities will participate or not in the 2004 sales tax holiday. I found that cities consider their own characteristics and their neighbor's characteristics when making the decision...
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 livestock, trees...
Entangled collaborations : a study of cross-disciplinary research collaboration in the field of user experience and data-intensive technologies in campus cyberinfrastructure
