Modeling Environmental Factors Related To Drought-Induced Tree Mortality Based On Lidar And Hyperspectral Imagery, Lauren Nicole Sharwood

Dissertations and Theses

Climate change is projected to bring more frequent and prolonged droughts, causing widespread forest die-off. Identifying tree mortality over large spatial extents in response to the most recent California drought will help forest managers and conservationists understand where there may be a greater likelihood of future die-offs. In order to find more at-risk areas, this study evaluated how interacting site-specific topographic, climate, substrate, and stand characteristics mediated tree mortality in the Central Sierra Nevada during the 2012-2016 drought. The author used lidar and hyperspectral imagery provided by the National Ecological Observatory Network to identify individual dead trees using the Random …

The Predictive Influence Of Challenging Behavior On Parent Stress In Young Children With Autism Spectrum Disorder, Paige Weir

LSU Master's Theses

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication, restricted interest, and repetitive patterns of behavior. Individuals with ASD also exhibit challenging behaviors that affect parent and caregiver stress directly. However, researchers have not yet examined the predictive influence of specific challenging behaviors on parent stress, particularly in young children (i.e., infants and toddlers) with ASD. Therefore, the current study expands existing literature by a) investigating the influence that challenging behaviors of young children with ASD have on parent stress and b) examining the unique contribution that each behavior (i.e., aggressive/disruptive behavior, stereotypy, and self-injurious …

Challenges Of Making Financial Decisions And Avoiding Fraudulent Schemes, Fabio Mattos

Cornhusker Economics

Last month there was an article in the local newspaper about a man accused of defrauding commodity investors for several years in Nebraska. This person is a commodity pool operator (CPO), who is an individual or organization that operates a commodity pool and solicits funds for that pool. A commodity pool is an enterprise in which funds contributed by a number of clients are combined for the purpose of trading futures contracts, options contracts, among other types of financial products. Generally speaking, a CPO manages an investment fund focused on commodity products.

Cetacean Acousticwelfare In Wild And Managed-Care Settings: Gaps And Opportunities, Paige E. Stevens, Heather Hill, Jason N. Bruck

Faculty Publications

Cetaceans are potentially at risk of poor welfare due to the animals’ natural reliance on sound and the persistent nature of anthropogenic noise, especially in the wild. Industrial, commercial, and recreational human activity has expanded across the seas, resulting in a propagation of sound with varying frequency characteristics. In many countries, current regulations are based on the potential to induce hearing loss; however, a more nuanced approach is needed when shaping regulations, due to other non-hearing loss effects including activation of the stress response, acoustic masking, frequency shifts, alterations in behavior, and decreased foraging. Cetaceans in managedcare settings share the …

Planning For Future Fire: Scenario Analysis Of An Accelerated Fuel Reduction Plan For The Western United States, Alan A. Ager, Cody Evers, Michelle A. Day, Fermin J. Alcasena, Rachel Houtman

Environmental Science and Management Faculty Publications and Presentations

Recent fire seasons brought a new fire reality to the western US, and motivated federal agencies to explore scenarios for augmenting current fuel management and forest restoration in areas where fires might threaten critical resources and developed areas. To support this effort, we modeled the scheduling of an accelerated forest and fuel management scenario on 76 western US national forests. Specifically, we modeled a 10-year ramp up of current forest and fuel management that targeted the source of wildfire exposure to developed areas and simulated treatment in areas that accounted for 77% of the predicted exposure. We used a sample …

Crop Insurance Premium Subsidies Influence On Family Farms, Cory Walters, Azzeddine Azzam, Taylor Kaus

Cornhusker Economics

The U.S. current taxpayer-subsidized crop insurance program represents a culmination of a series of legislative acts, beginning in 1980 with the Federal Crop Insurance Act, followed by the Federal Insurance Reform Act in 1994, and the Agricultural Risk Protection Act (ARPA) in 2000. All acts aimed at encouraging producer participation through increased premium subsidies and enhanced coverage options. Increased subsidization was effective in increasing participation, as more than 90% of corn acres were covered by some form of crop insurance by 2020. For 2021, premium subsidies in Nebraska for all crop insurance policies ranged from just over $36,000 in Hooker …

Synthesis Of A Multimodal Ecological Model For Scalable, High-Resolution Arboviral Risk Prediction In Florida, Sean P. Beeman

USF Tampa Graduate Theses and Dissertations

West Nile virus (WNV) and Eastern Equine Encephalitis virus (EEEV) represent the two greatest endemic arboviral risks to the state of Florida. Currently, no approved human vaccine exists for the prevention of either virus. In the absence of a vaccine, effective disease surveillance is paramount for public health. In Florida, WNV and EEEV sentinel chicken surveillance is conducted by mosquito control programs operated at the county, municipality, or special taxing district level. This program was implemented in 1978 following human outbreaks of St. Louis Encephalitis virus (SLEV) that occurred between 1959 and 1977, with initial sentinel coops placed in proximity …
