Soil surface-seal measurement using high-resolution x-ray computed tomography (HRCT)
(University of Missouri--Columbia, 2006)
Rainfall on bare soil breaks soil aggregates, detaching particles, plugging pores and decreasing porosity in the top few mm of soil. This reduces hydraulic conductivity and increases runoff through a process known as surface ...
Death and burial in ancient Alexandria: the Necropolis of Moustapha Pasha
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] As study of the Alexandrian monumental rock-cut tombs in the eastern necropolis of Moustapha Pasha, leads to a re-examination of their artifacts, ...
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)
- and 4-leaf plants are removed. If seed from harvested plants is sown at 2 cm, up to 52% of the 3-leaf and 62% of the 4-leaf plants can be harvested annually. Deer browse disproportionately affected reproductive stage classes. In the year following browse...
Evaluation and development of first order fire effects mortality model predictions for eastern hardwood forests
(University of Missouri--Columbia, 2018)
at the stand and individual tree levels by comparing outputs from FOFEM 6.4 to mortality observed at 5 prescribed burn studies across the eastern US. FOFEM was found to overestimate mortality for all sites and all species based on predicted crown scorch...
Investigation of smart work zone technologies using mixed simulator and field studies
(University of Missouri--Columbia, 2020)
Safety is the top concern in transportation, especially in work zones, as work zones deviate from regular driving environment and driver behavior is very different. In order to protect workers and create a safer work zone ...
The impacts of partner abundance on benefits from facultative pollination mutualism
(University of Missouri--Columbia, 2010)
Partner abundance affects costs and benefits in obligate mutualisms, but its role in facultative partnerships is less clear. I investigated this topic in a small alpine pollination web in the Colorado Rocky Mountains ...
An assessment of UAV technology and shattercane population dynamics to improve pest management
(University of Missouri--Columbia, 2023)
Unmanned aerial vehicles (UAVs) outfitted for pesticide application have the potential to improve application efficiency under conditions challenging for traditional, ground-based equipment. UAV-applied treatments had 21-32 ...
Habitual subsistence practices among prehistoric Andean populations: fishers and farmers
(University of Missouri--Columbia, 2006)
This research tested the hypothesis that it is possible to differentiate fishers from farmers using muscle marker patterns. Muscle markers are imprints (tuberosities, grooves, and/or bony projections) left on the skeleton ...
Approaches for unveiling the kinetic mechanisms of voltage gated ion channels in neurons
(University of Missouri--Columbia, 2019)
Ionic currents drive cellular function within all living cells to perform highly specific tasks. For excitable cells, such as muscle and neurons, voltage-gated ion channels have finely tuned kinetics that allow the ...
Canopy recruitment dynamics in naturally regenerated longleaf pine (pinus palustris) woodlands
(University of Missouri--Columbia, 2017)
The ecological and cultural values of the longleaf pine (Pinus palustris) ecosystem, in combination with an approximately 97 percent loss in historic range, has led to increasing interest in ecosystem restoration and ...
Applying deep learning technologies to discovery and characterization of genetic variants in animal genomes
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 12/1/2024] The scale of publicly available genomic data has rapidly expanded by an order of magnitude within the last decade. However, research with these aggregated public data requires minimizing the ...
Tales of an 'invisible' life stage : survival and physiology among terrestrial juvenile ambystomatid salamanders
(University of Missouri--Columbia, 2019)
The vital rates (e.g., survival, growth, and reproduction) of distinct life stages within a species are known to influence the growth and persistence of populations. As such, studies describing stage-specific vital rates, ...
Seasonality and elevational migration in an Andean bird community
(University of Missouri--Columbia, 2010)
Life history strategies of many birds in the Neotropics remain poorly known. In particular, details on the seasonal movements of individuals and populations within the Neotropics remain largely unknown, including short-distance ...
The socioeconomic and cultural significance of food gardening in the Vladimir Region of Russia
(University of Missouri--Columbia, 2008)
Russia's family gardens currently produce over half of the country's agricultural output and represent a major sector of the country's economy, involving two thirds of the population. Despite this prominence, household ...
Leveraging large scale beef cattle genomic data to identify the architecture of polygenic selection and local adaptation
(University of Missouri--Columbia, 2020)
Since the invention of the first array-based genotyping assay for cattle in 2008, millions of animals have been genotyped worldwide. Leveraging these genotypes offers exciting opportunities to explore both basic and applied ...
Knowledge construction, social identity and social network structure in completely online groups
(University of Missouri--Columbia, 2009)
Working, learning and informal information-seeking behavior is rapidly moving online. It will increasingly involve collaboration within small groups meeting online. While this process is being driven by technological ...
