Flower production and effect of flower harvest on berry yields within six American elderberry genotypes
(University of Missouri--Columbia, 2017)
production of American elderberry flowers is nascent. A large field experiment with American elderberry was established in 2015 in southwest Missouri, U.S.A to evaluate flower production and to determine the impact of a partial flower harvest on fruit yield...
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 ...
Northern bobwhite brood ecology and population dynamics in southwest Missouri
(University of Missouri--Columbia, 2020)
Northern bobwhite (Colinus virginianus) have experienced widespread, long-term population declines. Bobwhite populations in Missouri have declined 2.7% annually between 1966 and 2015, and 3.5% annually between 2005 and 2015, for a cumulative loss...
Looking broadly and deeply into perspectives of local climate change impacts among visitors to Missouri state parks
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Missouri's outdoor recreation resources provide numerous mental, physical, and social values to millions of people each year and serve as a major contributor to the statewide...
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 problem since the late 1970s...
Nitrogen management strategies to improve corn growth and reduce soil greenhouse gas emissions from claypan soils
(University of Missouri--Columbia, 2018)
. The objective of this study was to determine the effects of urea fertilizer placement with and without the addition of a nitrification inhibitor (NI) on corn yield, N use efficiency (NUE), and cumulative soil N[2]O emissions on a Northeastern Missouri claypan...
Utilizing hydrologic soil grouping to estimate corn nitrogen rate recommendations
(University of Missouri--Columbia, 2019)
Nitrogen fertilizer recommendations in corn (Zea mays L.) that match crop N need are imperative to increasing profitability and preventing environmental contamination. However, processes influencing corn production (i.e. ...
Investigating denitrification from two Missouri claypan soils
(University of Missouri--Columbia, 2020)
. The research sites consisted of two claypan soil fields in Central Missouri. Several sets of soil cores were collected in triplicate in two landscape transects across both fields and N2 and N2O production were measured using a gas flow soil core incubation...
Forage production and diversification for climate-smart tropical and temperate silvopastures
(University of Missouri--Columbia, 2019)
. We examined three distinct silvopastures, two in the country of Panama and one in the state of Missouri, to better understand how the integration of woody perennial trees and shrubs affects forage productivity, availability, and nutritional value...
Identification and characterization of health-promoting benefits and bioactive molecules in black walnuts (Juglans nigra l.) and waste materials from agroforestry systems

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 ...
Assessing red wolf conservation based on analyses of habitat suitability and human perception of carnivores
(University of Missouri--Columbia, 2018)
of carnivores was assessed from over 1,100 surveys distributed across a spectrum of natural resource and general events in Missouri and Arkansas, two regions that ranked high in habitat suitability. The majority of respondents had positive views based...
