Seasonal variation in nutrient availability and uptake by oak saplings following four nitrogen treatments on Missouri River floodplain
(University of Missouri--Columbia, 2008)
Bottomland restoration of native hardwood species provides a variety of benefits to the environment and the landowners. However, when reforesting agricultural floodplains along the Missouri River, high soil pH often causes nutrient deficiencies...
The potential of producing bioenergy crops on conservation reserve program land in Missouri, Iowa, Nebraska, and Kansas (MINK Region) to mitigate carbon dioxide emissions : an integrated economics and biological modeling approach
(University of Missouri--Columbia, 2010)
policymakers develop sustainable and balance of energy-agriculture-environmental policies....
Estimation of total height, growth, and mortality of forest trees in Missouri
(University of Missouri--Columbia, 2005)
A model for predicting total tree height as a function of tree diameter was calibrated for twelve tree species common to the Missouri Ozarks. Model coefficients were derived from nearly 10,000 observed trees. The calibrated model did a good job...
A multi-configuration evaluation of the soil and water assessment tool (SWAT) in a mixed land use watershed in the central U.S.A.
(University of Missouri--Columbia, 2011)
. Watershed and soil resolution had negligible impact; climate input had considerable impact. Single climate station input is best used for applications requiring monthly predictions; distributed climate station input is needed for daily predictions. SWAT...
Factors influencing upland oak advance reproduction in the Missouri Ozarks
(University of Missouri--Columbia, 2011)
in the Missouri Ozarks, we used regression models for estimating the advance reproduction density of red oaks, white oaks, and non-oaks. The abundance of red oak advance reproduction was smaller on northeast-facing slopes and inversely related to soil plant...
Effects of prescribed burning in Missouri Ozark upland forests
(University of Missouri--Columbia, 2007)
Prescribed fire is used in Missouri to achieve various silvicultural goals, but the use of burning in upland Ozark forests raises many questions that research has yet to answer. The purpose of this study is to examine the effects of prescribed...
Quantifying riparian canopy energy attenuation and stream temperature using an energy balance approach
(University of Missouri--Columbia, 2011)
of the central U.S. Hydroclimate data were collected from two intensively instrumented stream reaches of opposite orthogonal compass orientation in a semi-karst watershed on the border of southern Missouri's Ozark region, USA, during the 2010 water year. Data...
Stand structure development effects on wood quality of Melina (Gmelina arborea roxb.)
(University of Missouri--Columbia, 2009)
A stem analysis was perform to examines the effects of thinning treatments on Melina (Gmelina arborea) wood quality and tree architecture in the North Coast of Colombia. 27 plots under forest management regimes and age ...
Long-term study of successional trends in an oak-dominated forest of central Missouri
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Changes in species composition and forest structure were studied over a 36-year period in the Baskett Research and Education Area (BREA) in central Missouri. Permanent plots were...
Economic analysis of woody biomass harvesting in the Missouri Ozarks
(University of Missouri--Columbia, 2010)
An integrated mechanized timber harvest thinning treatment to remove small diameter trees and merchantable saw logs was conducted on 30 acres of the Missouri, Ozarks in the summer of 2009. Two silvicultural treatments (single tree selection...
Evaluation of the Private Forestland Ownership Paracelization and its effects on the forest landscape in the southeastern Missouri Ozarks
(University of Missouri--Columbia, 2005)
This study investigates the impacts of the forestland ownership parcelization on species composition, age structure and spatial pattern of the forest landscape. First, a computer model was developed to create ownership ...
Macroinvertebrate assemblage composition along a longitudinal multiple-land-use gradient in a midwestern stream
(University of Missouri--Columbia, 2012)
Land use changes often alter hydrogeomorphology and hydrologic flow regimes, which can adversely impact stream aquatic biota. Hinkson Creek Watershed (HCW, 231km2) located in Boone County, central Missouri, is comprised of 50% agriculture, 26...
Detection and modeling of bat species occupancy at multiple scales across a forested landscape in southeastern Missouri
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Populations of forest dwelling bats have been in decline in recent years, and have therefore become increasing foci in forestry research efforts. Difficulty in bat species...
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)
Matrix population analysis was used to analyze eight years of demographic data from six American ginseng (Panax quinquefolius L.) populations in east-central Missouri to examine effects of herbivory by white-tailed deer (Odocoileus virginianus Zimm...
Woody species and forest structure in northern Missouri riparian forests with different ages and watershed sites
(University of Missouri--Columbia, 2006)
A chronosequence (1 to 250+ years) of 160 woody species plots was established throughout northern Missouri riparian forests to explain the influence of site hydrology and stand age on species distribution and forest structure. Stand age was found...
Linking ecological and social dimensions of Missouri landscapes
(University of Missouri--Columbia, 2005)
A recent study by the Brookings Institution concluded that patterns of growth in Missouri are eroding the quality of life and rural heritage, and threatening the environment. Reversing these trends will require better understanding the relationship...
A multi-dimensional investigation into the effects of flooding on the physical, chemical and biotic properties of riparian soils
(University of Missouri--Columbia, 2008)
