Cover crop effects on soil moisture dynamics & thermal properties
(University of Missouri--Columbia, 2021)The climate change induced weather uncertainty has increased the environmental extremes such as severe droughts and floods affecting volumetric soil moisture content (θ), thus food security. It also has increased the weather ... -
Determining electrofishing response thresholds of smallmouth bass (micropterus dolomieu), flathead catfish (pylodictus olivaris), and blue catfish (ictalurus furcatus)
(University of Missouri--Columbia, 2018)We examined the response to electrofishing of three Missouri sportfish: Smallmouth Bass, Blue Catfish, and Flathead Catfish. We had three objectives for this research effort: 1) determine the effective conductivity of each ... -
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 ... -
Educating for adoption : understanding long-term outcomes of the Agroforestry Academy
(University of Missouri--Columbia, 2020)Agroforestry adoption remains low in temperate regions despite academic acceptance of diverse benefits. And while education is often cited as a tool for empowering adoption, researchers have struggled to identify generalizable ... -
Effect of climate change, drought, and insects on oak-pine forests in the Ozark highlands
(University of Missouri--Columbia, 2020)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Oak-dominated forests in the Ozarks Highlands of Arkansas and Missouri have been suffering severe oak decline and this became a chronic ... -
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 large fires on boreal forests of China : historical reconstruction and future prediction through landscape modeling
(University of Missouri--Columbia, 2020)Boreal forests of China store about 350 Tg tree biomass carbon, which is approximately 24–31 [percent] of the total forest carbon storage in China, and thus, play an important role in maintain national carbon balance. ... -
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 ... -
ENSO and PDO related variability in seasonal range prediction for the Bolivian Altiplano region in South America
(University of Missouri--Columbia, 2019)This study uses the methodology of some experiences in seasonal range prediction related to El Niño-Southern Oscillation (ENSO) and Pacific Decadal Oscillation (PDO) in North America. Previous studies (e.g Garreaud and ... -
ENSO and PDO-related variability in South Pacific circulation patterns and seasonal range prediction for Bolivia in South America
(University of Missouri--Columbia, 2018)Seasonal range prediction over North America has been based on intraseasonal and interannual variability related to the Pacific North America (PNA) pattern and El Nino and Southern Oscillation (ENSO), respectively. These ... -
Estimating above and below ground vegetation biomass and carbon storage across an intra-urban land-use gradient in mid-Missouri
(University of Missouri--Columbia, 2015)*Urbanization includes a gradient of disturbance along which impacts on vegetative communities can widely vary. Urban forests play a vital role as carbon sinks for atmospheric carbon dioxide. In order to further understanding ... -
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, ... -
Evaluating phytochemical contributions to atrazine degradation
(University of Missouri--Columbia, 2020)Surface water contamination from the herbicide atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) has been a concern for many years. The use of vegetated buffer strips (VBS) is known to improve water quality ... -
Evaluation and development of first order fire effects mortality model predictions for eastern hardwood forests
(University of Missouri--Columbia, 2018)The First Order Fire Effects Model (FOFEM) is a useful tool for predicting fire-induced mortality in western coniferous forests. However, it lacks robust models for eastern hardwood species. Managers in the eastern United ... -
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 ... -
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 ... -
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 ... -
Exploring positive youth development and civic engagement in an environment action program : a Saint Louis Zoo case study
(University of Missouri--Columbia, 2020)To become thriving and contributing members of society, a vital skill for youth to learn is civic engagement behaviors. Civic engagement can manifest itself as volunteering, community engagement, or behaviors such as voting ... -
Factors influencing practitioner adoption of agroforestry : a USDA SARE case study
(University of Missouri--Columbia, 2020)Agroforestry practices offer a compelling alternative to conventional agriculture as they provide a broad range of economic, ecological and social benefits. Despite its' recognized potential, on-the-ground adoption of U.S. ... -
Flower production and effect of flower harvest on berry yields within six American elderberry genotypes
