Voices Of The Often Unheard: The Environmental Impacts Of Catastrophic Wildfire Events On Individuals With Developmental Disabilities, Mary Madison Mckenzie
Voices Of The Often Unheard: The Environmental Impacts Of Catastrophic Wildfire Events On Individuals With Developmental Disabilities, Mary Madison Mckenzie
Graduate Student Theses, Dissertations, & Professional Papers
The Thomas Fire for a time was the largest wildfire in California history, burning 281,893 acres and destroying 1,063 structures. Within three years, the August Complex Fire, at 1,032,649 acres, almost quadrupled that record. Climate related disasters such as these have impelled social science researchers to heed calls for a paradigm shift in understanding the risks climate change poses to the social world, in particular, disaster risks for vulnerable groups. Existing research tends to focus on disasters such as hurricanes, featuring risks for vulnerable populations by race, class, and/or individuals with disabilities in general, but not for individuals with developmental …
Catch My Drift? Perceptions And Experiences Of Pesticide Contamination Of Organic Crops In Montana, Sarah Rodgers
Catch My Drift? Perceptions And Experiences Of Pesticide Contamination Of Organic Crops In Montana, Sarah Rodgers
Graduate Student Theses, Dissertations, & Professional Papers
Pesticide drift and inadvertent contamination pose particular risks to organic production. Some organic producers have lost their crops, certification, and/or organic markets because of contamination events. Through this thesis research, I explain the perceptions and experiences that certified organic farmers in Montana have about drift and inadvertent pesticide contamination. I conducted semi-structured interviews with eleven certified organic farmers from various regions of Montana. Along with one-on-one interviews with organic farmers, interviews with industry and regulatory officials were conducted to better understand the policies and procedures that control what happens when drift occurs at the state level. Industry and regulatory official …

Combined Effects Of Temperature And Heavy Metals On The Performance Of The Giant Salmonfly., James Frakes, Amanda Andreas, Benjamin P. Colman, Aurthur Woods
Graduate Student Theses, Dissertations, & Professional Papers
In many freshwater ecosystems, communities of aquatic insects are facing the combined stresses of warmer waters due to climate change and increased exposure to heavy metal toxicants. Although each stressor may threaten aquatic insects independently, they also likely interact in important ways to affect insect physiology and performance. Here we investigate this potential interaction using two populations of aquatic nymphs of the giant salmonfly, Pteronarcys californica, collected from adjacent rivers in Montana: naïve individuals from Rock Creek, a relatively pristine stream, and individuals from the Upper Clark Fork River, which has a history of heavy metal pollution and higher …
Exploring Visitor Perceptions And Behaviours Related To Ticks And Lyme Disease Risk In An Ontario Protected Area, Ryan Brady
Theses and Dissertations (Comprehensive)
Lyme disease is the most common vector-borne zoonosis in North America and over the past decade, reported cases of the disease have been rapidly increasing in many regions throughout Canada. The relative novelty of this public health threat presents nature-based tourism and recreation organizations with a range of policy and management challenges. Currently, there is a limited understanding of public perceptions and behaviours associated with tick and Lyme disease risk, especially within a Canadian parks and protected areas visitation and visitor experience context. To address this practical and scholarly knowledge gap, this study utilized in-situ surveys to explore visitor perceptions, …

Plastic Recycling Is Inefficient And Expensive, Clark S. Adomaitis
Plastic Recycling Is Inefficient And Expensive, Clark S. Adomaitis
Capstones
Plastics production and incineration contributes more than 850 million metric tons to the emissions that are causing climate change. Emissions are growing at a moment when scientists and world leaders are in agreement that they need to dramatically decrease. Environmentalists say that plastic production makes up 4.5% of global greenhouse gas emissions. New plastic plants opening in the U.S. do not line up with emission reduction goals.
At the end of plastics’ lives, a lot of what we’re putting into our recycling bins isn’t getting recycled. In fact, only 18% of trash from New York City homes is actually recycled. …

Assessing The Potential For Lightning-Induced Damage In Commercial Broiler Houses In Mississippi And Alabama, Matthew R. Rowland
Assessing The Potential For Lightning-Induced Damage In Commercial Broiler Houses In Mississippi And Alabama, Matthew R. Rowland
Theses and Dissertations
Modern broiler houses are expensive to build, maintain, and insure. Protecting them from extreme weather events is a major concern to producers, integrators, and insurance companies. Lightning strikes can cause catastrophic fires and electrical damage and can lead to costly bird losses. A greater understanding of the impact of lightning on the commercial broiler industries of MS and AL is needed. The objectives of this research were collection of baseline resistance data for broiler houses and equipment in both states, and mapping lightning strike densities across MS and AL, evaluating annual, monthly, seasonal, and diurnal patterns. 63.5% of surveyed broiler …

In 2020, residences used 16.5% of all final energy in the United States, and residences were responsible for 19.3% of all U.S. CO2 emissions. Calvin ENGR 333 students partnered with Habitat for Humanity to tackle the issue of carbon emissions when designing their homes. Habitat for Humanity for Kent County is endeavoring to design homes that reduce energy consumption, energy expenditures, and carbon emissions. They are embarking upon a “carbon footprint build” that will minimize energy consumption and carbon emissions, both during construction and across the lifetime of their new Habitat for Humanity homes. This semester, the senior mechanical engineering …

Habitat for Humanity (HFH) requested a carbon footprint analysis of their most recent home build. Mark Ogland-Hand, a representative of HFH, connected with Professor Heun’s ENGR 333 students to perform the carbon footprint analysis on their new low carbon house. Assuming Consumer’s Energy will incorporate their predicted percentage of renewables into their electric grid, the London home reduces projected carbon emissions by 18% when compared to a “To Code” house over a 25 year lifespan. For the current Consumer’s Energy grid, the “Improved” London house is shown to reduce projected carbon emissions by 30% when compared to the current London …

Root-microbiome interactions are of central importance for plant performance and yield. A distinctive feature of legumes is that they engage in symbiosis with N2-fixing rhizobia. If and how the rhizobial symbiotic capacity modulates root-associated microbiomes are still not yet well understood. We determined root-associated microbiomes of soybean inoculated with wild type (WT) or a noeI mutant of Bradyrhizobium diazoefficiens USDA 110 by amplicon sequencing. UPLC-MS/MS was used to analyze root exudates. The noeI gene is responsible for fucose-methylation of Nod factor secreted by USDA 110 WT strain. Soybean roots inoculated with the noeI mutant showed a significant decrease …

In 2020, residences used 21% of all final energy in the United States and were responsible for 20% of all U.S. carbon dioxide emissions (henceforth referred to as carbon emissions). Habitat for Humanity for Kent County is endeavoring to design homes that reduce energy consumption, energy expenditures, and carbon emissions. They have established a goal of a “low carbon footprint build” that will minimize energy consumption and carbon emissions, both during construction and across the lifetime of the house.

Habitat for Humanity (HFH) built a low-carbon home at 726 London Street SW. Mark Ogland-hand, a representative of HFH, connected with Professor Matthew Heun to begin a carbon study of this new home with the goals of understanding the carbon footprints of a traditional HFH home, the London home, and future improvements feasible for HFH to make in reducing the carbon emissions of their houses.
