Agroforestry education for high school agriculture science : a case study of novel content implementation
(University of Missouri--Columbia, 2017)High school agriculture science programs are recognized as meaningful arenas to reach young agriculture professionals as they gain a foundational understanding of their field. While sustainability is at the forefront of ... -
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 ... -
Comparison of dual-polarization radar-derived and disdrometer drop-size distributions with S- and X- band radars
(University of Missouri--Columbia, 2017)There have been many studies on the evaluations of drop-size distributions and the parameters that affect these distributions, however, few, if any, have directly compared the relationship between the radar-derived parameters ... -
Effects of fire and thinning on Kansas oak woodlands
(University of Missouri--Columbia, 2017)Prior to Euro-American settlement, a mosaic of prairie, savanna, woodland, and forest existed within the Forest-Prairie Transition Region of the United States, with anthropogenic fire acting as an important driver in the ... -
Effects of stand density on mitigation and adaptability to climate change in pine and hardwood forests of Missouri
(University of Missouri--Columbia, 2017)Understanding how forests respond to traditional management in the context of climate change is increasingly important for developing multi-objective management strategies. In the Missouri Ozarks, the influence of long-term ... -
An evaluation of historical fire occurrence, drought, and the El Niño southern oscillation in the greater Cross Timbers region, U.S.A
(University of Missouri--Columbia, 2017)A concern over wildfire occurrence, and its relationship to drought and a changing climate has brought increased focus to the interface between the public and fire. Multiple factors, including an increase in fuel loading ... -
Flower production and effect of flower harvest on berry yields within six American elderberry genotypes
(University of Missouri--Columbia, 2017)Cultivation of American elderberry (Sambucus canadensis) is increasing in North America for its use in dietary supplements. While the flowers of European elderberry (S. nigra) are commonly consumed as an anti-viral in ... -
Identifying bioactive phytochemicals in spent coffee grounds for cosmetic application through global metabolite analysis
(University of Missouri--Columbia, 2017)Annually, more than 6 million tons of spent coffee grounds (SCG) are generated worldwide. The present study explores the possible use of spent coffee grounds as the raw materials for cosmetics industry. The main objective ... -
Impacts of forest management on medicinal herbs in the Missouri Ozarks
(University of Missouri--Columbia, 2017)As agroforestry becomes more accepted in the Midwestern US, understanding how non-timber forest product growth is impacted by forest management practice becomes increasingly important. Timber harvest and prescribed fires ... -
Nitrogen and harvest impact on warm-season grass biomass yield and feedstock quality
(University of Missouri--Columbia, 2017)Perennial warm-season grasses including switchgrass (Panicum virgatum L.), big bluestem (Andropogon geradii Vitman), and Indiangrass (Sorghastrum nutans L.) have drawn interest as bioenergy feedstocks due to their high ... -
The predictability of Northern Hemispheric blocking using an ensemble mean forecast system
(University of Missouri--Columbia, 2017)Some weather extremes can be the result of atmospheric blocking. Like atmospheric patterns that tend to repeat themselves, atmospheric blocking leads to the stagnation of weather patterns. This repetition can last for ... -
Soil quality assessment for an alfisol undergoing alternative organic weed management systems
(University of Missouri--Columbia, 2017)As organic agriculture farmland continues to increase on a global scale with 6.5 million hectares added during 2014-2016, the increased number of organic producers will be expected to fulfill sustainability obligations. ... -
Use of non-lethal endpoints to establish water quality requirements and optima of the Topeka Shiner (notropis topeka)
(University of Missouri--Columbia, 2017)Water quality influences growth, development, and physiology of aquatic vertebrates. Current criteria on water quality assessments are primarily based on lethal level experiments (e.g. LC50 tests), which are poorly suited ...
