Persistent organic pollutant effects on middle Mississippi River Scaphirhynchus sturgeon reproduction and early life stages
(University of Missouri--Columbia, 2011)
Pallid sturgeon (Scaphirhynchus albus) and shovelnose sturgeon (Scaphirhynchus platorynchus) populations have been in decline over the past century and contaminants may be a contributing factor. Two studies were designed ...
The use of geomorphological and pedological soil characteristics to assess planar borrowing at a Mandan Indian village, North Dakota
(University of Missouri--Columbia, 2011)
The Double Ditch State Historic Site is situated in a loess landscape immediately east of the Missouri River near Bismarck, North Dakota. The site was occupied from ca AD 1450 to 1785 by Mandan Indians, Plains Villagers ...
Soil microbial contribution to greenhouse gas efflux from a secondary forest in central Missouri
(University of Missouri--Columbia, 2011)
Greenhouse gas emissions (GHG) vary with the interactions among physical, chemical, and biological characteristics of soil and microclimate. Soil microorganisms are involved in almost all soil processes, and are also ...
Regional and geomorphic influence on soil genesis and oak ecosystems in the Chariton River Hills of Missouri
(University of Missouri--Columbia, 2011)
Little is known about soil, geomorphic, and vegetation relationships in the moderately-dissected glaciated forests of the Chariton River Hills Ecological Subsection (CRHES). To gain a better understanding of these relationships ...
The verification of weather forecasts compared to numerical model guidance, climatology, human forecasts and seasonal variations
(University of Missouri--Columbia, 2011)
The accuracy of weather forecasts has been a topic of discussion for many years, and a simple but useful method for showing forecast accuracy has been an issue for meteorologists over time. My study on the comparison of ...
Effects of selected surfactants on nutrient uptake and soil microbial community
(University of Missouri--Columbia, 2011)
Surfactants with solvent and wetting abilities are used in the formulation of herbicides to enhance spraying capabilities. These chemicals eventually enter into the soil and may disrupt different chemical, physical and ...
Habitat and management effects on foraging activity of Indiana bats (Myotis sodalis) in northern Missouri
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The federally endangered Indiana bat (Myotis sodalis) uses fragmented forests in largely agricultural landscapes during the maternity season. Understanding ...
Quantifying suspended sediment loading in a mid-Missouri urban watershed using laser particle diffraction
(University of Missouri--Columbia, 2011)
Midwestern streams and rivers of the United States are known for high suspended sediment concentrations (SSC), which is also one of the leading sources of water impairment. Unfortunately, there is a lack of understanding ...
Sorption and transport of veterinary antibiotics in agroforestry buffer, grass buffer, and cropland soils
(University of Missouri--Columbia, 2011)
Understanding sorption and transport of veterinary antibiotics (VAs) is important for assessing the risk of VAs reaching water resources. Vegetative buffer strips (VBS) may be a useful tool for mitigating veterinary ...
Factors affecting spatial and temporal dynamics of an ungulate assemblage in the Black Hills, South Dakota
(University of Missouri--Columbia, 2011)
Our goal was to gain empirical data on the spatial and temporal selection of resources by the ungulate assemblage in Custer State Park (CSP), South Dakota. To achieve this goal, we developed a spatially-explicit model to ...
Investigation of an invasive crayfish and its relation to two imperiled native crayfishes; anthropogenic influences, multi-scale habitat associations, and conservation options
(University of Missouri--Columbia, 2011)
The introduced Woodland Crayfish (Orconectes hylas) is spreading throughout the St. Francis River, Missouri. The imperiled Big Creek Crayfish (Orconectes peruncus) and St. Francis River Crayfish (Orconectes quadruncus) are ...
The verification of weather forecasts, numerical modeling, climatology, and variations in enso cycles in forecast accuracy
(University of Missouri--Columbia, 2011)
Weather forecasting has been a difficult problem for meteorologist for more than one hundred years. In the early days, our understanding of atmospheric processes was limited by our incomplete understanding of the governing ...
U.S. consumer preferences for elderberry products
(University of Missouri--Columbia, 2011)
Increased production of North American Elderberry (Sambucus canadensis) for its use in value-added secondary products is a prime example of the growth in non-traditional agroforestry product markets. Nonetheless, greater ...
Natal dispersal and survival of red-bellied woodpeckers in a fragmented landscape
(University of Missouri--Columbia, 2011)
Survival and dispersal during the juvenile life stage are critical to population connectivity and persistence, but the post-fledging period is the least studied stage of the avian life cycle. We intensively radio-tracked ...
Silvopasture's effect on growth and development of white and black oaks in an intensively managed upland central hardwood forest
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Silvopasture is a practice that integrates elements of forest management, pasture management and livestock husbandry in a mutually beneficial manner ...
Quantifying riparian canopy energy attenuation and stream temperature using an energy balance approach
(University of Missouri--Columbia, 2011)
Forested riparian buffers play an important role in modulating stream water quality, including temperature. Few studies have quantified the relationship between stream temperature and canopy cover in the climatologically ...
Fuel management considerations in Caribbean pine forests of the mountain pine ridge of Belize, Central America
(University of Missouri--Columbia, 2011)
Situated within the Maya Mountains of Central America, the Mountain Pine Ridge (MPR) ecosystem encompasses approximately 76,000ha (107,000 acres) within the country of Belize. Dominated by Caribbean pine (Pinus caribaea), ...
Early-age genetic parameter estimates for diameter, height and volume in Pinus echinata mill. and implications for breeding
