Fire risk assessment of the western portion of the central hardwoods forest region
(University of Missouri--Columbia, 2008)
forests, determine the temporal variability in fuel accumulation rates, and quantify the role of topographic roughness in fire regimes. Using knowledge gained from these case studies two regional scale studies were conducted describing 1) variability...
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 classes were evaluated. Split...
Factors influencing upland oak advance reproduction in the Missouri Ozarks
(University of Missouri--Columbia, 2011)
Successful oak stand regeneration requires an abundance of well developed advance reproduction. Past studies have found that oak reproduction varies on upland landscapes by inferred measures of nutrient and water supply ...
Estimation of total height, growth, and mortality of forest trees in Missouri
(University of Missouri--Columbia, 2005)
predicting the mean height-diameter trend for each species (pseudo-R2 values ranged from 0.56 to 0.88), but for a given tree diameter observed tree heights were highly variable. In addition, an evaluation of the Central States variant of the Forest Vegetation...
Validating Missouri landtype associations using tree species composition, forest structure, and productivity
(University of Missouri--Columbia, 2005)
Missouri's Landtype Associations (LTAs) were delineated from 1995-1998, and are currently being used by natural resource managers, but these LTAs have never undergone a validation showing that they can encompass patterns ...
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...
Effects of light availability and herbivory on planted white oak (Quercus alba) seedlings and acorns
(University of Missouri--Columbia, 2022)
from 800 planted bare-root white oak seedlings across 32 experimental units located in the river hills region of Missouri. Experimental units were equally divided between two different upland oak stands in order to contrast the responses of underplanted...
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)
-benefits including improvement of soil and water quality in the MINK region. The environmental results indicate that the level of biomass yields and change in soil organic carbon differ with type of bioenergy crop, soil type, climatic conditions, and cultural...
The socioeconomic and cultural significance of food gardening in the Vladimir Region of Russia
(University of Missouri--Columbia, 2008)
of a 2006 survey of 1,500 families in the Vladimir region, show that gardens not only perform a wide range of economic, social and cultural functions, but also represent a highly sustainable practice embedded in the region's and the country...
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)
multi-objective auto-calibration better predicted monthly flow (PBIAS=1%, NSE=0.8) than single-objective calibration (PBIAS=16%, NSE=0.5). SWAT performs well in Central U.S. urbanizing watersheds. Accuracy can improve with auto-calibration as presented...
The survival and growth of shortleaf pine systems in the Missouri Ozarks : effects of competition, genetics, and site preparation
(University of Missouri--Columbia, 2019)
Establishing shortleaf pine (Pinus echinata) across portions of its historical range has proven challenging due to shade intolerance, slow early growth, and poor competitive ability. The objectives of this study were to ...
Analysis of landscape characteristics surrounding deer vehicle accidents in St. Louis County, Missouri
(University of Missouri--Columbia, 2008)
in regions with average road density relative to other roads in St. Louis County, and close to grasslands. The analysis and model can be used as predictive tools during road planning and assessment stages. They will also be useful for identifying areas...
Ambrosia beetle habitat use, host use, and influence on early wood colonizing microbes in an oak-hickory forest
(University of Missouri--Columbia, 2010)
native and seven exotic ambrosia beetle species occurred in a central Missouri oak-hickory forest, however, the exotic component dominated the ambrosia beetle community. Stand characteristics influenced ambrosia beetle abundance but not the percent...
Designing a LANDIS PRO harvest module and examining the effects of temporal resolution on simulation outcomes
(University of Missouri--Columbia, 2012)
The development and testing of forest landscape models is an ongoing process. This thesis documents a portion of this process working with the LANDIS PRO 7.0 forest landscape model in two parts. In the first chapter I ...
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 ...
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. ...
