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 ...
Measuring and modeling suspended sediment and nutrient yields in a mixed-land use watershed of the central United States
(University of Missouri--Columbia, 2016)
Science-based information is needed to better understand mixed-land-use contributions of suspended sediment and nutrient loads to receiving water bodies. Water samples were analyzed for suspended sediments and nutrients ...
Analysis of severe elevated thunderstorms using DCIN and DCAPE
(University of Missouri--Columbia, 2018)
A 10-year study of elevated severe thunderstorms was performed using The National Centers for Environmental Information (NCEI) Storm Report database. This research further corroborates previous studies of occurrence, ...
Estimating the water budget of extratropical cyclones with the precipitation efficiency
(University of Missouri--Columbia, 2018)
Estimating the water budget of three mid-latitude extratropical cyclones is attempted from the perspective of the precipitation efficiency (PE), using a method proposed for the study of convective columns. Using a lagrangian, ...
Interpreter perceptions of climate change and impacts in Missouri state parks
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Parks are an ideal setting for climate change communication because visitors have an affinity for natural and cultural resources. Interpretation, an ...
Nitrogen management strategies to improve corn growth and reduce soil greenhouse gas emissions from claypan soils
(University of Missouri--Columbia, 2018)
Adoption of nitrogen (N) management strategies to minimize gaseous N loss from agriculture while maintaining high yield production is increasingly important for an exponentially growing population. Agricultural management ...
An integrated modeling approach for estimating the potential hydrologic impacts of urbanization and climatic changes in Hinkson Creek watershed
(University of Missouri--Columbia, 2016)
Land-use changes and climatic changes are two of the most significant phenomena impacting water regimes globally. Since ongoing land-use changes in the form urbanization and projected climate changes are expected to have ...
An evaluation of Discover Nature Schools /
(University of Missouri--Columbia, 2017)
Fidelity of implementation (FOI) is the extent to which a program is implemented as designed. There needs to be more work on conceptualizing and measuring FOI in conservation education programs. There also needs to be a ...
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 ...
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 ...
Developing and evaluating the effectiveness of a place based climate change education toolkit in Missouri
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Climate change is the most serious environmental issue facing humans in modern society. It is more relevant today than ever before since a massive ...
Integrated regional enstrophy and its correlation with regime transitions in the Northern Hemisphere
(University of Missouri--Columbia, 2019)
Integrated regional enstrophy (IRE) is the enstrophy integrated over a portion of the globe at a specific level in the atmosphere. Previous work has shown this quantity is correlated to the positive Lyapunov Exponent for ...
Managerial perceptions and responses to climate change in Missouri state parks and historic sites
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Climate change has been described as one of the greatest, long-term challenges facing modern society. Its impacts range from alteration of ecosystem ...
Assessment and diversity of fish communities in non-wadeable tributaries of the Missouri and Mississippi rivers
(University of Missouri--Columbia, 2020)
As the geographical centers of riverscapes, rivers support fish populations at local and basin-wide scales. However, refinements to fish sampling protocols and theories underpinning basin-wide community ecology have been ...
The variability of the El Nino southern oscillation and Modoki mode and their impacts on New York State climate
(University of Missouri--Columbia, 2020)
The El Nino Southern Oscillation (ENSO) has long been an influential climate and weather driver for many regions. Many studies have examined the variability of the phases of ENSO, leading to discovery of a separate mode ...
Exploring educational values of deliberative pedagogy as a means of climate change communication
(University of Missouri--Columbia, 2020)
Climate change is a major obstacle facing the world today, impacting the environment and communities across the globe. With rising greenhouse gas emissions and subsequent rising surface temperatures, evidence shows that ...
Using soil moisture as a predictor for spring convection within the state of Missouri
(University of Missouri--Columbia, 2020)
Previous studies have shown that increased soil moisture can affect the overlying water vapor in the atmospheric boundary layer (ABL), potentially moistening this layer. Increased buoyancy can create more turbulence and ...
Habitat use and distribution of lithophilic spawning and riffle fishes in the East Fork Black River
(University of Missouri--Columbia, 2020)
Freshwater streams are dynamic ecosystems that house diversity of taxa adapted to and dependent on habitat characteristics these flowing systems. Conservation of these ecosystems, requires an understanding of the abiotic ...
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 ...
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 ...
