Decision Support Tools To Address Climate Change: Climate Model - Land Surface Models, Zea Mays L. (Corn) Phenology And Evapotranspiration-Yield Sensitivity Models For Nebraska, Usa., Jane A. Okalebo
School of Natural Resources: Dissertations, Theses, and Student Research
Nebraska's climate is highly variable and is expected to change in the future with anthropogenic global warming (AGW), resulting in warmer spring and summer temperatures coupled with more erratic rainfall events. This has strong implications for agriculture in the region, yet it is not clear that current modeling and decision-support tools are adequate to address these looming changes and provide planning, mitigation and adaptation strategies. To address climate change and its implications to agriculture in Nebraska, a set of robust decision support tools are very crucial. This study herein are divided into three chapters, with each chapter addressing a specific …
Development Of A Public Education Website: Building Bridges Over Water, Angelina Mckee
Development Of A Public Education Website: Building Bridges Over Water, Angelina Mckee
Agricultural Education and Communication
Website created by Angelina McKee to educate the public about water resource issues. Water is the basic unit of life, water resources are the basis for what societies and ecosystems are founded upon. Water shortages and droughts are more prevalent in our ever-changing world. It is no shock that there are discrepancies between various stockholders on either sides of the dry riverbed. This senior project resulted in the development of a website that addresses global water resources, water use in California, water conservation, and water allocation. The website informs the public on water resources and related issues and will hopefully …
Water Water Everywhere: Analyzing Long Island's Water Issues And Finding Solutions For A Sustainable Future, Anthony T. Becker
Water Water Everywhere: Analyzing Long Island's Water Issues And Finding Solutions For A Sustainable Future, Anthony T. Becker
2014 Student Theses
Over three million people call Long Island their home. With access to beautiful landscapes, world-renowned beaches, and proximity to New York City, it is no wonder that so many proudly call this geographic stretch of glacial till their home. However, throughout the years our actions do not necessarily reflect this affection we have to our home. Years of sprawl and human infestation across the island have resulted in widespread environmental degradation. Specifically, the water we drink and the beaches we enjoy have become endangered. I plan on studying the urban ecology of how intensified population growth led to the eutrophication …
Agriculture, Environmental Restoration And Ecosystem Services: Assessing The Costs Of Water Storage On Agricultural Lands In South Florida, Kayla Ouellette
Agriculture, Environmental Restoration And Ecosystem Services: Assessing The Costs Of Water Storage On Agricultural Lands In South Florida, Kayla Ouellette
USF Tampa Graduate Theses and Dissertations
A large part of the environmental restoration required by the Comprehensive Everglades Restoration Plan calls for more water-storage on lands south of Lake Okeechobee in order to restore the natural water flows of the Everglades watershed. The Everglades Agricultural Area (EAA) can be used for increased water storage in order to relieve coastal estuaries of excess water in the rainy season. This water storage can deliver additional ecosystem services of soil retention and reduced CO2 emissions that could compensate farmers for the cost of water storage by increasing long term farm profitability. The goals of this study were 1) to …
Improving The Microbial Source Tracking Toolbox : Evaluating The Use Of Selective Enrichments And Artificial Sweeteners In A Multi-Tiered Approach, Stacey A. Helming
Improving The Microbial Source Tracking Toolbox : Evaluating The Use Of Selective Enrichments And Artificial Sweeteners In A Multi-Tiered Approach, Stacey A. Helming
Legacy Theses & Dissertations (2009 - 2024)
Microbial contamination of surface waters is a public health concern world-wide, with non-point source fecal input contributing to millions of cases of waterborne illness annually. Numerous techniques have been proposed to monitor for non-point source fecal contamination, but few studies have explored the correlation of multiple chemical and microbial fecal source tracking markers in ambient waters. Therefore, the purpose of these studies was to evaluate the use of multiple "ideal" markers of fecal contamination and improve upon any analytical techniques required to identify species-specific fecal contamination in surface waters. The use of selective enrichments to improve the sensitivity of end-point …

We present a two-step algorithm for the detection of seafloor propeller seagrass scars in shallow water using panchromatic images. The first step is to classify image pixels into scar and non-scar categories based on a sparse coding algorithm. The first step produces an initial scar map in which false positive scar pixels may be present. In the second step, local orientation of each detected scar pixel is computed using the morphological directional profile, which is defined as outputs of a directional filter with a varying orientation parameter. The profile is then utilized to eliminate false positives and generate the final …
