Characteristics of Herbicides and Weed-Management Programs Most Important to Corn, Cotton, and Soybean Growers
(AgBioForum, 2009)
The introduction and rapid adoption of herbicide-tolerant crops has renewed interest in better understanding the characteristics of herbicides and weed-management programs that are important to growers besides profitability. ...
Three essays on phosphorus runoff and water quality
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Water pollution caused by nutrients, and the resulting eutrophication, have increased over time. This water pollution is increasingly caused by non-point source pollution, both...
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...
Determinants of Beef and Pork Brand Equity
(2003-11)
A set of consumer-level characteristic demand models were estimated to determine the level of brand equity for pork and beef meat cuts. Results indicate that brand premiums and discounts vary by private, national, and store ...
Upper Shoal Creek Watershed: Water Quality Analysis
(Food and Agricultural Policy Research Institute (FAPRI) at the University of Missouri-Columbia, 2004-02)
FAPRI, with significant input from the local community, has developed this analysis defining how current agricultural practices in the upper Shoal Creek Watershed affect water quality....
Climate and land use effects on hydrologic processes and water allocation in a primarily rain-fed, agricultural watershed
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] There is a need to raise our understanding of the impact of climate variability and change on hydrologic processes at the watershed scale. This is important, particularly...
Three essays on biofuel policies and aggregate supply curve
(University of Missouri--Columbia, 2022)
The first essay investigates the impacts of Brazil's new biofuel policy, namely RenovaBio. RenovaBio aims to reduce greenhouse gas (GHG) emissions in the transportation sector through expansion of biofuels by requiring ...
Plant community response during establishment of woodland silvopasture in the Missouri Ozarks
(University of Missouri--Columbia, 2022)
Disturbance-mediated oak (Quercus spp.) woodlands were formerly a prevalent community type in Missouri, and their restoration is a key objective of land management agencies and conservation organizations. Over one-third of wooded land in Missouri (2...
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 ...
Wildlife response to spatial and temporal changes in forest habitat
(University of Missouri--Columbia, 2008)
A common goal in land-management planning is to describe the relationship between management actions, vegetation and wildlife habitat conditions for large landscapes. Achieving this goal can be challenging because ecological ...
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 ...
Alternative certification science teachers' understanding and implementation of inquiry-based instruction in their beginning years of teaching
(University of Missouri--Columbia, 2006)
, 2000) or inquiry as modeled in activities used in their ATCP. The research participants' perceived constraints and needs in their implementation of inquiry-based activities. Their perceived constraints included logistical and student constraints...
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...
Avian nest survival and breeding density in cottonwood plantations and native forest fragments in southeast Missouri
(University of Missouri--Columbia, 2008)
