Rock Climbing And Conservation In Land Management: Can They Coexist?, Marissa Heller

Geography ETDs

As participation in outdoor recreation is growing in the U.S., a dilemma is presented for conservation planners and land area managers who must manage the increasing demand for recreation while simultaneously working to protect species. Rock climbers and other outdoor recreationalists have asserted that a relationship exists between recreation and the conservation of public lands. However, mounting evidence suggests that rock climbing continues to cause a multitude of negative impacts to ecosystems. Here, I investigate the extent to which land management practices allow for rock climbing and conservation to coexist, and how it is that well developed plans protect ecologically …

Environmental Communication: Changing The Attitude-Behavioral Gap In Science Communication Utilizing Strategic Messaging, Carrie Helgeson Nelms

Graduate Theses and Dissertations

National Polls in the United States consistently find the public’s beliefs and attitudes about climate change and other environmental issues significantly diverge from those held by the science community. A communication gap between the findings on the causes and effects of environmental issues and the public’s inability to interpret or refuse to accept these findings are possible causes of this divergence. This communication gap constitutes a threat to society because of inaction to environmental problems and points to needed changes in scientific messaging that better informs and motivates behavioral change. The present research employed a strategic message design to affect …

Assessing Consumer Demand, Producer Profitability, And The Environmental Impacts Of Conservation Agriculture Adoption In Sub-Saharan Africa, Willy Byamungu Mulimbi

Graduate Theses and Dissertations

This dissertation explores three aspects of conservation agriculture (CA) in the Sub-Saharan African region (SSA). The first article examines the demand side of CA and explores whether urban maize (Zea mays L.) consumers in the Democratic Republic of the Congo (DRC) would be willing to pay a premium for CA-produced maize flour. The second article estimates the effects CA provides to adopters and their farms in smallholder farming systems in the DRC, focusing on changes in soil properties and cowpea (Vigna unguiculata) yields. The final article uses a Life Cycle Assessment (LCA) approach to monetize the environmental impacts of adopting …

Gaging Downstream Transport Of Cyanobacteria In The Raritan River Basin, Kyle R. Clonan

Theses, Dissertations and Culminating Projects

Cyanobacteria dominated Harmful Algal Blooms (HABs) have the potential to release toxic compounds harmful to human health. Few studies have examined the potential for cyanobacteria travelling from lacustrine HAB sources through fluvial systems used for potable water supply. The Raritan Basin Water Supply Complex (RBWSC) sources potable water for several utilities serving more than 1.5 million people in central New Jersey. The RBWSC features three lentic waterbodies with persistent HABs; discharges from these waterbodies all reach the downstream drinking water intakes. The objectives of this study were to 1) review the persistence of cyanobacteria during fluvial transport from upstream, cyanobacteria-dominated …

Simulating The Changes Of Invasive Phragmites Australis In A Pristine Wetland Complex With A Grey System Coupled System Dynamic Model: A Remote Sensing Practice, Danlin Yu, Nicholas A. Procopio, Chuanglin Fang

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Biological invasion has been one of the reasons that coastal wetlands gradually lose their ecological services. The current study investigates the spread of a commonly found invasive species in coastal wetlands in Northeastern US, the Phragmites australis. Within a relatively pristine wetland complex in coastal New Jersey, we collected high-resolution multispectral remote sensing images for eight years (2011–2018), in both winter and summer seasons. The land cover/land use status in this wetland complex is relatively simple, contains only five identifiable vegetation covers and water. Applying high accuracy machine learning algorithms, we are able to classify the land use/land cover in …

Forest Carbon Incentive Programs For Non-Industrial Private Forests In Oregon (Usa): Impacts Of Program Design On Willingness To Enroll And Landscape-Scale Program Outcomes, Rose A. Graves, Max Nielsen-Pincus, Ryan D. Haugo, Andres Holz

Environmental Science and Management Faculty Publications and Presentations

Privately-owned forests in the Pacific Northwest (PNW) are important potential carbon sinks and play a large role in carbon sequestration and storage. Non-industrial private forest (NIPF) owners constitute a substantial portion of overall forest landownership in productive regions of the PNW; however, little is known about their preferences for non-market incentive programs aimed at increased carbon storage and sequestration, specifically by limiting timber harvest, and how those preferences might impact the outcome of forest carbon programs. We simulated landscape-scale outcomes of hypothetical forest carbon incentive programs in western Oregon (USA) by combining empirical models of NIPF owners' participation with spatially …

Modern Pyromes: Biogeographical Patterns Of Fire Characteristics Across The Contiguous United States, Megan E. Cattau, Adam Mahood, Jennifer K. Balch, Carol Wessman

Human-Environment Systems Research Center Faculty Publications and Presentations

In recent decades, wildfires in many areas of the United States (U.S.) have become larger and more frequent with increasing anthropogenic pressure, including interactions between climate, land-use change, and human ignitions. We aimed to characterize the spatiotemporal patterns of contemporary fire characteristics across the contiguous United States (CONUS). We derived fire variables based on frequency, fire radiative power (FRP), event size, burned area, and season length from satellite-derived fire products and a government records database on a 50 km grid (1984–2020). We used k-means clustering to create a hierarchical classification scheme of areas with relatively homogeneous fire characteristics, or modern …

Bird Use Of Avocado Farms And Intact Forest In The Dominican Republic, Avery Young

Masters Theses and Doctoral Dissertations

The Dominican Republic, a conservation priority area due to high rates of bird endemism and overwintering Neotropical migrant habitats, is seeing an increase of avocado farms and a subsequent forest loss. We conducted point-count bird surveys to determine how avian species richness and diversity differ between avocado farms and intact forest, as well as how vegetation differences between farms and forests could impact bird use. We found that vegetation structure varied significantly between farm and forest sites, but that overall bird diversity and migrant diversity did not. However, we found that endemic bird species showed higher species richness and diversity …

Design trends are constantly in flux, but the reasons why people prefer new trends are not readily apparent. This thesis brought together multiple aspects of interior design to investigate how design has changed. After a review of available studies, the researcher decided to focus on natural design in homes because this area has previous research upon which to build. This study compared data to examine how stress in America relates to plant imagery. The research questions asked what, if any, relationship exists between societal stress and the use of plants, plant-like objects, and window views.

Measures of stress included hospitalization, …

Organizational Green Claims And Consumer Green Perceptions In The Foodservice Industry, Jangwoo Jo

Electronic Theses and Dissertations

Due to the ever-growing consumer demands and global pressures for more sustainable business operations, corporations disclose their sustainable practices, products, and services to enhance their environmental image. Consumer green perceptions resulting from those organizational green claims have not been the focus of foodservice research. The application of green performance dimensionality of the foodservice domain identified that organizational green claims regarding food, environment and administration increase consumer green confusion and green trust at the same time. Based on the results of CFA, SEM, and multigroup analyses, this study suggests implications both theoretical and practical.

Evaluation Of Life Cycle Costs, Benefits, And Public Perceptions Of Greywater Reuse Systems For Supplementing Conventional Water Delivery, Sreeganesh Reddy Yerri

All Dissertations

The water utility industry is under enormous pressure to meet the challenges of increasing demands due to population growth, lifestyle changes, and depleting freshwater resources. The current and predicted future deficit scenarios challenge water supply managers to come up with a sustainable and reliable alternative source while making the supply infrastructure smarter and resilient. One such alternative source is the greywater that is available at the point of consumption itself. With certain limitations, there have been studies performed to evaluate the life cycle costs and expected monetary benefits of decentralized greywater reuse systems, but the public and health bureaus are …

A Cross-Scale Nexus: Microbial Functional Genes In Tandem With Molecular-Level Nitrogen Fluxes And Implications For Field-Scale Biogeochemical Processes, Srusti Maddala

Graduate Theses and Dissertations

Nitrogen (N) biogeochemical cycling entails close networking between soil nutrients, plant species and resulting microbial communities, and abiotic factors such as temperature, moisture, and pH. To better understand transformations of N in soil microsites, which are known to be rich in N-cycling behavior, the microdialysis technique was employed to generate in situ data on temporal alterations of N during wetting-drying conditions in both the field and laboratory. The objectives were to 1) determine the lifespan of the microdialysis technique in field conditions, 2) evaluate the ability of the method to yield N fluxes that would be differential between the two …

A Dynamic Relationship With Wilderness: Comparing Day And Multi-Day Visitors' Indicators Of Quality In Wilderness Settings, Caleb Meyer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The length of stay in wilderness areas is declining and, in many areas, day visitors comprise most of all use. Most prior research exploring this trend took place in the 1990s and few studies of wilderness visitation account for the increase in outdoor recreation participation over the last decade. Lack of understanding surrounding this trend raises questions about managerial and philosophical approaches to the recreation-wilderness relationship. This study explored these topics within visitor use management approaches used by the National Park Service, which manages the proposed Glen Canyon Wilderness, near Escalante, Utah, where this research took place.

Results of this …

A Social-Ecological Approach To Understanding The Structure, Function, And Challenges Faced By Fisheries, Chase C. Lamborn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fisheries throughout the world play many important roles, and they are also subject to many pressures. The tension between roles and pressures is increasing, and as a result, many fisheries are being utilized to, or over their capacity, which ultimately threatens their sustainability. To address these challenges, this dissertation provides insights and tools to help us better understand fisheries and the challenges they face. The first study explores the impacts of an earlier spring runoff in Montana. Earlier runoff has resulted in lower and warmer summer flows, which is stressing coldwater species like trout. This stress is affecting fishing quality, …
