Adoption of Recombinant Bovine Somatotropin and Farm Profitability : Does Farm Size Matter?
(AgBioForum, 2010)
This article analyzes the adoption and profitability of recombinant bovine somatotropin (rBST) in the United States. Probit model results show that location of the farm, farm size, operator age and education, and other ...
Restoration treatments and regeneration dynamics in East Texas mixed wood forests
(University of Missouri--Columbia, 2023)
Extensive harvesting, fire exclusion, and plantation forestry altered composition and structure, and thus function and habitat values of east Texas Pineywoods uplands. Upland restoration efforts are made difficult by the ...
An Analysis of the retention, condition and land use implications of tree plantings established under the Soil Bank Program, the Forestry Incentives Program and the Agricultural Conservation Program
([Missouri Agricultural Experiment Station], 1994)
Muse, number 36-38 (2002-2004)
(University of Missouri, Museum of Art and Archaeology, 2008)
Intraguild interactions between native and domestic carnivores in central India
(University of Missouri--Columbia, 2008)
Bustard Sanctuary, Maharashtra, India and assessed resource selection based on landcover characteristics. Indian foxes chose for grassland habitats at the scale of both landscape and home-range level and avoided human-dominated areas such as agricultural...
Winter bird densities and eastern wood-pewee breeding demography across a savanna-woodland-forest gradient in the Missouri Ozarks
(University of Missouri--Columbia, 2012)
and woodland is needed to inform management. Our objective was to determine densities of common winter migrants and resident birds in savannas, woodlands, and non-managed forests in the Missouri Ozark Highlands. We estimated detection probabilities...
The effects of overstory retention on species composition and height growth following clearcut and group selection regeneration harvests in the Missouri Ozark Highlands
(University of Missouri--Columbia, 2019)
The objectives of this study focus on whether treatment and aspect significantly influence tree regeneration. This study utilizes data from 16-year-old clearcuts and group openings within the Missouri Ozarks to assess the height and quantity...
Drainage water management practices affect water quality, soil properties, and crop production
(University of Missouri--Columbia, 2023)
. This dissertation includes results from four studies conducted at the MU Greenley Research Center, Grace Greeley farm, and Ross Jones farm. Long-term, no-till research evaluated the influence of a wheat (Triticum aestivum L.), radish (Raphanus raphanistrum subsp...
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 ...
Pre-harvest water quality of ephemeral streams in Missouri Ozark forests
(University of Missouri--Columbia, 2006)
The Missouri Department of Conservation (MDC) developed a best management practice that leaves a riparian buffer next to streams to reduce the possibility of water quality degradation. The purpose of this study is to quantify water quality in upland...
The demography of Atlantic brant (Branta bernicla hrota)
(University of Missouri--Columbia, 2022)
for greatest understanding of population level processes and to inform prioritization of conservation efforts for Atlantic brant. Future brant research should focus on nutrient dynamics of James Bay staging areas, identifying core breeding areas and quantifying...
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 ...
An investigation of urban bat ecology in Baltimore, Maryland
(University of Missouri--Columbia, 2019)
help determine what bat species were present and how active these species were. Research occurred in Baltimore, Maryland, a 'shrinking' city in the eastern US, which had no prior research on the bat community. For my first project, I used active...
"Send only your serious cases" : delivering flu to Toronto: an anthropological analysis of the 1918-19 influenza epidemic in Toronto, Ontario, Canada
(University of Missouri--Columbia, 2010)
This project looks at the 1918-19 pandemic influenza experience in Toronto, Ontario, Canada. Based on historical records (most notably death registries and archival material) this work strives to understand the social, biological, and environmental...
Impacts of suspended and deposited sediment on benthic invertebrates and fishes in a Missouri Ozark stream
(University of Missouri--Columbia, 2006)
Sediment is suspected in the decline of sensitive-aquatic organisms in the Osage River basin of Missouri. In this study, I monitored sediment dynamics and evaluated corresponding linkages with benthic invertebrate and fish assemblages as it related...
An evaluation of pre- and post-timber harvest water quality in low-order streams in the Missouri Ozarks
(University of Missouri--Columbia, 2009)
Missouri Department of Conservation's (MDC) best management practices (BMPs) for Regenerative Oak Clear Cutting (ROCC) practice was evaluated on effectiveness to preserve downstream water quality. Fifteen sites, located on MDC lands in Shannon...
Pediatric Lead Poisoning and The Built Environment in Kansas City, Missouri 2000-2013
(2021)
This study examines relationships between pediatric lead poisoning and the built environment. Focusing on Kansas City, Missouri between the years 2000 and 2013 this dissertation informs policy options and identifies under-explored lines of inquiry...
Effects of prescribed fire and timber harvest on terrestrial salamander abundance, behavior, and microhabitat use
(University of Missouri--Columbia, 2014)
surveys for three years and used a statistical modeling approach that accounted for the tendency of terrestrial salamanders to be belowground and unavailable for surveys. I found that terrestrial salamander density at our Missouri Ozark study site ranged...
