Modeling the financial impact of management decisions on loblolly pine (Pinus taeda) production
(University of Missouri--Columbia, 2010)
Located primarily in the southeastern United States, Loblolly pine (Pinus taeda L.) is a variety of Southern yellow pine that is often planted by non-industrial private landowners seeking a beneficial long-term investment ...
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...
Designing a LANDIS PRO harvest module and examining the effects of temporal resolution on simulation outcomes
(University of Missouri--Columbia, 2012)
and testing of a disturbance module that simulates harvest events in the LANDIS PRO model. The design operates on quantitative attributes such as number of trees and basal area to control harvest events, giving the user the ability to parameterize harvest...
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)
Concerns about global warming and climate change have generated increasing interest in development of bioenergy crops as a potential source of low-carbon energy. The goal of this research was to quantify environmental and ...
Quantifying riparian canopy energy attenuation and stream temperature using an energy balance approach
(University of Missouri--Columbia, 2011)
/ and 0.25 m3/s within the E-W and N-S reaches respectively. Mean stream temperature was greatest in August and was 24.4 [degrees]C in the E-W reach and 24.0 [degrees]C in the N-S reach. Net shortwave radiation was the primary energy flux causing stream...
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)
- and 4-leaf plants are removed. If seed from harvested plants is sown at 2 cm, up to 52% of the 3-leaf and 62% of the 4-leaf plants can be harvested annually. Deer browse disproportionately affected reproductive stage classes. In the year following browse...
Restoring forest composition and structure of riparian corridors in the Missouri Ozarks
(University of Missouri--Columbia, 2008)
on the 1) artificial regeneration of 13 native bottomland tree species, 2) composition of natural tree regeneration, and 3) composition, structure, and diversity of the resulting ground flora at three riparian sites in the Missouri Ozarks. Choice of tree...
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...
The survival and growth of shortleaf pine systems in the Missouri Ozarks : effects of competition, genetics, and site preparation
(University of Missouri--Columbia, 2019)
survival and growth rates of planted shortleaf pine relative to artificial and natural hardwoods, identify barriers to regeneration success, and develop tools for individual tree assessment. Data from three long-term studies in southeastern Missouri were...
Developing a stand density module in LANDIS to improve simulation realism of stand dynamics
(University of Missouri--Columbia, 2009)
Long-term landscape modeling is dependent on various forest dynamics including large-scale disturbances, environmental effects, land management and stand-scale succession. The stand density module was designed for LANDIS ...
Woody species and forest structure in northern Missouri riparian forests with different ages and watershed sites
(University of Missouri--Columbia, 2006)
by watershed size. There were seven significant trends in the tree-watershed data: 1) very flood tolerant species importance values increased in larger watersheds; 2) shade tolerance was the dominant mechanism structuring riparian communities; 3) watershed size...
Simulating cottonwood tree growth in flood plains using the LIGNUM modeling method
(University of Missouri--Columbia, 2006)
simulation model, was applied to simulation of the cottonwood growth in a flood plain area in central Missouri. The key characteristics of the LIGNUM model are the linkage between tree spatial structure and physiological function. L-system was adopted...
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 ...
Ferns as a forest farming crop: effects of light levels on growth and frond quality of selected speicies with potential in Missouri
(University of Missouri--Columbia, 2006)
In Missouri 11.3 million acres of commercial forests are privately owned. The vast majority is under very little - if any - management. Agroforestry, specifically forest farming, has the potential to provide producers an opportunity to put...
Fertilizer effects on soil pH, soil nutrients, and nutrient uptake in swamp white and pin oak seedlings on an alkaline Missouri River bottomland
(University of Missouri--Columbia, 2008)
There is growing interest among forest and wildlife managers in the reforestation of bottomlands with mast producing hardwoods in the Lower Missouri River and Mississippi River Alluvial valleys. However, it is common for bottomland hardwood...
Insight into the roles of prescribed fire and hardwood competition in the survival and growth of shortleaf pine throughout its early life
