Occupancy modeling of forest carnivores in Missouri
(University of Missouri--Columbia, 2008)
My research used infrared remote cameras, trackplate boxes, and scat transects to survey for carnivores at 53 sites throughout the southern forested region of Missouri. Cameras and track-plates both detected Eastern spotted skunk (Spilogale putorius...
Golden-cheeked warbler nest success and nest predators in urban and rural landscapes
(University of Missouri--Columbia, 2007)
We studied nesting success of Golden-cheeked Warblers (Dendroica chrysoparia) from 2005-2006 in urban and rural landscapes in central Texas. We used an information-theoretic approach to evaluate models representing hypotheses ...
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...
River restoration in the upper Mississippi River Basin
(University of Missouri--Columbia, 2006)
River restoration has become an important management choice to address causes and effects of surface water impairment and river modification in the Upper Mississippi River Basin (UMRB). I report information on individual UMRB river restoration...
Biomass production of five populus clones, soil carbon and soil water content in a central Missouri floodplain
(University of Missouri--Columbia, 2006)
Five Populus clones in two short rotation 5 year plantations were tested for biomass production and associated soil C changes in the central Missouri floodplain under climatic conditions of the Midwest. A Populus deltoides x Populus nigra (Eugenei...
Effects of amending a gravel based growing medium with calcined clay on medium physical properties and growth of Gymnocladus dioicus seedlings
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Missouri Gravel Bed (MGB) is a system that uses pea gravel with 10% sand (v/v) as a root growth medium, allowing bare root plants to be removed from the gravel and planted...
Analysis of twenty-five years of heavy rainfall events in the Texas Hill Country
(University of Missouri--Columbia, 2008)
climate stations in the region; the period examined for this study was 1982-2006. Days with measurable precipitation were treated as a gamma distribution in order to determine the top 2%, 1%, and 0.5% to define events as unusual, rare, and extreme...
Avian nest survival and breeding density in cottonwood plantations and native forest fragments in southeast Missouri
(University of Missouri--Columbia, 2008)
I compared nest survival and breeding density between native bottomland forest and cottonwood (Populus deltoides) plantations over a three-year period for Acadian Flycatcher (Empidonax virescens), Prothonotary Warbler ...
Nutrients, chlorophyll and bacterial fecal indicators in coves and open water areas of Lake of the Ozarks, Missouri
(University of Missouri--Columbia, 2009)
Urban development and use of septic tanks in porous soils of Lake of the Ozarks poses a threat to public health via leaching into drinking wells and coves used for swimming. During 2 summers, phosphorus (TP), nitrogen (TN), ...
Reflectance sensors to predict mid-season nitrogen need of cotton
(University of Missouri--Columbia, 2008)
Nitrogen (N) is an essential nutrient for cotton production; consequently there is a tendency to over-apply nitrogen. High N causes excessive vegetative growth and delayed crop maturity, which result in increased cost in ...
Atrazine transport through a glacial till aquifer in north-central Missouri
(University of Missouri--Columbia, 2009)
Although the claypan of North Central Missouri is traditionally believed to protect the groundwater from contamination, low concentrations of the herbicide atrazine have been detected in a shallow glacial till aquifer. The fate of the atrazine...
Evaluation and development of black-footed ferret resource selection models
(University of Missouri--Columbia, 2009)
Resource selection function (RSF) and utilization function (RUF) models aid in evaluating habitat suitability and investigating hypothesized mechanisms of space use of wildlife. We monitored postbreeding resource selection ...

Impact of aphids species and barley yellow dwarf virus on soft red winter wheat
(University of Missouri--Columbia, 2005)
Barley yellow dwarf virus is one of the most widespread viral diseases of wheat. Yield reductions up to 70% have resulted from barley yellow dwarf virus (BYDV) infection. Several aphid spp. transmit BYDV. In Missouri, the four common aphids...
