Environmental Racism In A Growing City: Investigating Demographic Shifts In Salt Lake City's Polluted Neighborhoods, Emma Nathel Jones

Undergraduate Honors Capstone Projects

Studies investigating the spatial distribution of environmental hazards have repeatedly demonstrated the existence of environmental racism -- the disproportionate impact of environmental hazards on communities of color. We aim to contribute to research on environmental racism by asking how relationships between race and hazard exposure change over time. Our study area, Salt Lake City (SLC), UT, USA is one of the largest cities in the intermountain west and is expected to see continued population growth. SLC was 99% white from 1860-1950. 2019 census estimates indicate that SLC is becoming more racially diverse with 35.6% of the population identifying as racial …

International Revitalization: A Study Of Projects From The Intermountain West And Iberian Regions Of The Globe, Emmalee Mangum

Undergraduate Honors Capstone Projects

The focus of this study was to study the characteristics of three projects in the Intermountain West region of the United States and three projects in the Iberian region of Europe to analyze the differences within the profession of landscape architecture around the world. The project begins by defining urban revitalization and its importance in the development of urban spaces, as well as studying two projects where urban revitalization attempts were not successful. Then, each project was studied in detail to learn how the project was started and the desired outcome of each project. This study included the "big picture" …

Impacts Of Hydroelectric Dams On Aquatic Macroinvertebrate Oviposition Strategies: The Role Of Desiccation, Jesse R. Fleri

Undergraduate Honors Capstone Projects

Previous studies quantifying the density, distribution and diversity of aquatic insects overwhelmingly focus on larval life stages. However, many aquatic insects exhibit selective oviposition behaviors, with a preference for emergent substrates along a river's edge. The practice of hydropeaking creates an artificial intertidal zone that is absent from natural rivers and to which freshwater organisms are not adapted. We hypothesized that this novel disturbance could reduce the availability and temporal persistence of oviposition habitats resulting in egg mortality. To test this hypothesis, we quantified the oviposition behavior of four aquatic insects using a hierarchical field survey of habitat availability and …

China: Avoiding Impediments To Successful Climate Change Mitigation, Molly Rose Van Engelenhoven

Undergraduate Honors Capstone Projects

This paper uses the Cultural Topography (CTOPs) methodology, an intelligence community standard which is used to avoid ethnocentric analysis and the dangerous practice of mirror imaging--projecting US culture on to another country rather than viewing the costs and benefits they face through their own cultural lens. CTOPs assess a country’s culture by examining four components of culture: identity, values, norms, and perceptual lens of an actor in conjunction with a specific issue of concern. This paper examines the internal culture of China, with the Chinese government as the key actor, to discover how to build effective policy to regulate air …

Stomatal Differences In Western Aspen And Linkage To Drought Tolerance, Brianne Palmer

Undergraduate Honors Capstone Projects

Aspen (Populus tremuloides) is the most widely distributed broadleaf forest tree in North America. However, aspen are declining rapidly in areas of the Intermountain West. Aspen in this area are prone to experiencing limited moisture and high temperatures. An important aspect of plant physiology when dealing with these stressors is stomatal function. Stomata control the rate of photosynthesis, therefore, the size and frequency of the stomata is likely to influence the survival of the species in this environment.

An unusual feature of aspen is the high frequency of triploidy in the southern portion of its range. Stomata! size …

Biodiversity Prioritization: A Comparison Of Data Types, Kari Norman

Undergraduate Honors Capstone Projects

The identification of important areas for biodiversity is essential for effective allocation of limited conservation resources. Prioritizing regions for conservation based on biodiversity is typically done using global biodiversity maps created using range map data for one or more taxa. While the use of range maps makes pragmatic sense since large-scale survey data is rarely available, it is important to understand the sensitivity of the results to the use of range map data. We studied how prioritizations may change between data types using the North American Breeding Bird survey (BBS) and BirdLife International range maps as a comparison case study. …

Empowering Community Partners: A Case Study Motivating Environmentally Sustainable Behavioral Changes In Latino Migrant Agricultural Families, Jessica Ivy Thomson

Undergraduate Honors Capstone Projects

Environmental sustainability outreach programs can benefit significantly through adaptation that connects to and fosters change within the Spanish speaking community. This article demonstrates a case study in which the authors partnered with a local Latino organization through an undergraduate service-learning project. The goal of this project was to incorporate environmentally sustainable behaviors both with young Latino students in school and with their families at the household level.

Assessing Attitudes Towards Global Climate Change Among Utah State University Faculty, Amy C. Rohman

Undergraduate Honors Capstone Projects

Climate change is a polarizing issue in which there are significant differences in perception between the scientific community and the general public. The intergovernmental Panel on Climate Change (IPCC) has formally acknowledged an increasing body of evidence that supports primarily human-caused climate change. No scientific organization has dissented, and over thirty national academies of the sciences have issued joint declarations confirming the evidence of anthropogenic climate change. Therefore, polarization is not caused by a lack of available scientific information. This study surveys Utah State University faculty to solicit their knowledge of and attitudes towards global climate change. Responses are assessed …

Application Of Habitat And Occupancy Modeling To A Wood Duck Next Box Program, Jason D. Carlisle

Undergraduate Honors Capstone Projects

Programs to augment wood duck (Aix sponsa) nesting habitat by providing artificial nest boxes are commonly implemented. In northern Utah, where such programs are relatively new, I proposed a method to identify sites suitable for deployment of next boxes through a combination of habitat and occupancy modeling using site-specific, biotic, and abiotic, data collected from 105 next boxes over one nesting season in Cache County, Utah. An inductive habitat model was first developed which identified possibly suitable habitat (8.74% of county) based on proximity to hydrologic features. Next, based on comparing competing single-species, single-season, occupancy models using a modified Akaike's …

Open Space Changes: A Formal Analysis In Cache Valley, Utah, Cameron Scott Bodine

Undergraduate Honors Capstone Projects

Open spaces are a valuable amenity that people often overlook. Open spaces allow for a system of water treatment, wildlife habitat, agricultural production, and recreation destinations. Too often, however, open space systems are systematically devoured by development with little regard of what that can mean for the future of a community. This thesis suggests that when open space systems are analyzed as having structure, shape, and a dynamic nature, interconnected with development, then an explanation of how it transforms and evolves can emerge. This thesis seeks to present a new method of describing open space change through understanding development trends …

Recreational Use Of Montane Streams Of The Puerto Rican Rainforest, Summer Kartchner

Undergraduate Honors Capstone Projects

As the population of the small island of Puerto Rico increases, so do the number of recreationists in natural areas. With increasing pressure on finite resources, managers must understand how humans are using these resources in order to conserve without limiting visitor satisfaction.

Characterization Of Dielectric Properties Of Earth Materials At Low Frequencies, Tarrah Dawn Henrie

Undergraduate Honors Capstone Projects

Sharma and de Lima (1992) have proposed a model based on Fixman's theoretical development of charged macromolecules in external fields (1980). There are three types of charges considered: the fixed surface charges that are covalently bonded, the layer of bound counterions, and the diffuse layer (Fixman, 1980, Lyklema, 1983 ). Figure (1) shows these different layers. Other common theories, such as Schurr's only consider the bound counterions and the diffuse layer. Schurr assumes that the diffuse layer ions can exchange with the electrolyte. A consequence of this assumption is the lack of polarization of the diffuse layer. This leads to …

What Limits Tailed Frog Tadpole Density And Distribution In Western Montana Streams?, Megan Barker

Undergraduate Honors Capstone Projects

We explored the possible limitation of temperature and other habitat features on tailed frog tadpole populations in northwestern Montana. We sampled densities and habitat features in two regions with different climatic regimes and in streams with and without tadpoles, expecting larger density and size in the warmer region. We also expected habitat conditons to be more optimal (higher gradient, swifter velocity, and less canopy cover) in streams with tadpoles. Temperature appeared to positively influence tadpole size, though both tadpole size and density were strongly correlated with other variables. Density was correlated with gradient, canopy, depth, and elevation, whereas length was …

A Forest Kingdom Unlike Any Other, Kurt F. Ruppel

Undergraduate Honors Capstone Projects

Olympic National Park (ONP), a natural area 15% larger than Rhode Island, located on the Olympic Peninsula in northwestern Washington State, is a land of diverse contrasts and impressive beauty. It is also a land rich in natural resources (e.g. timber, water power, and recreational potential) that are strongly coveted by man. This dichotomy has led to a number of conflicts during the past hundred years over the policies directing the control, management, and use of this area. It is the purpose of this paper to examine the factors that have shaped that policy and to follow the changes that …
