Simulating cottonwood tree growth in flood plains using the LIGNUM modeling method
(University of Missouri--Columbia, 2006)
As a flood-tolerant and fast-growing species, cottonwood is a promising species in flood plain and short-rotation forestry. Understanding tree growth will provide critical assistance in flood plain forest management and ...
Utilizing on-line surveys to gather data: an application to help evaluate Missouri's interpretive programs
(University of Missouri--Columbia, 2005)
Most state and federal agencies involved in the management of natural resources offer educational programs that serve several purposes. In Missouri, the Departments of Conservation and Natural Resources play this vital ...
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 ...
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 ...
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 ...
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 ...
Effects of regeneration harvests on stand development and oak (Quercus spp.) regeneration through 15 years in bottomland hardwood forests of Northern Missouri
(University of Missouri--Columbia, 2016)
Bottomland hardwood forests provide important economic and ecological values within the midwestern United States, yet silvicultural guidelines for reaching management objectives have been poorly developed outside the ...
Modeling regeneration and early stand dynamics of Missouri Ozark forests
(University of Missouri--Columbia, 2015)
Projecting the effects of silvicultural choices on forest regeneration has traditionally been difficult. In an effort to improve upon this, a collection of empirical models based on leading hypotheses and theories of tree ...
The Land Capability Potential Index: a decision support tool for the management of Missouri River floodplain habitat
(University of Missouri--Columbia, 2015)
The Land Capability Potential Index (LCPI) is a hydrogeomorphic model of potential flow-return interval and soil drainage developed as a decision support tool for the restoration and management of floodplain habitat on the ...
Conservation payments to reduce tropical deforestation and degradation : evidence from the Ecuadorian Andes to the Amazon basin
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Payment for Environmental Services (PES) are market-based policy instruments. Which compensate private resource managers financially for the environmental ...
Investigating soil carbon, nitrogen and respiration across an intra-urban gradient in mid-Missouri
(University of Missouri--Columbia, 2015)
Carbon (C) storage by urban soils is an attractive option to reduce atmospheric CO2. However, C dynamics are complicated by the gradient of land use and vegetation assemblages associated with urban development. Soil total ...
Effects of biochar on yield and nitrogen nutrition of warm-season biomass grasses
(University of Missouri--Columbia, 2015)
Majority of the global energy supply depends on fossil fuel sources such as coal, petroleum, and natural gas. However, energy production by these sources has significant environmental impacts such as air and water pollution, ...
Ozark ground flora response to landscape-scale prescribed fire
(University of Missouri--Columbia, 2015)
Restoration of natural communities has increasingly become important to many organizations. One challenge to restoration of natural communities is understanding how to best assess restoration success when several metrics ...
The socioeconomic and cultural significance of food gardening in the Vladimir Region of Russia
(University of Missouri--Columbia, 2008)
Russia's family gardens currently produce over half of the country's agricultural output and represent a major sector of the country's economy, involving two thirds of the population. Despite this prominence, household ...
A multi-dimensional investigation into the effects of flooding on the physical, chemical and biotic properties of riparian soils
(University of Missouri--Columbia, 2008)
Understanding soil abiotic and biotic influences on ecosystem processes will enhance success of riparian restoration efforts. The goal of this research was to characterize changes in soil chemical and microbial community ...
