The Road That Made Mountains: Highway Design And The Production Of Landscape In Vail, Colorado, James T. Lindberg

Theses - ALL

Constructed between 1972 and 1978, Vail Pass is a 16-mile section of Interstate-70 that crosses the continental divide in the Central Mountains of Colorado. It connects the ski resort communities of Copper Mountain and Vail and has played a significant role in the development of tourism in the Colorado High Country. The design and planning of Vail Pass occurred at a time of increased public concern over environmental issues, and was built following a series of significant pieces of federal environmental legislation. Within this context, highway designers and engineers sought to harmoniously integrate the highway into its natural setting.

Foliar Application Of Low Concentrations Of Titanium Dioxide And Zinc Oxide Nanoparticles To The Common Sunflower Under Field Conditions, Marek Kolenčík, Dávid Ernst, Martin Urík, Ľuba Ďurišová, Marek Bujdoš, Martin Šebesta, Edmund Dobročka, Samuel Kšiňan, Ramakanth Illa, Qian Yu, Huan Feng, Ivan Černý, Veronika Holišová, Gabriela Kratošová

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Nano-fertilisers have only recently been introduced to intensify plant production, and there still remains inadequate scientific knowledge on their plant-related effects. This paper therefore compares the effects of two nano-fertilisers on common sunflower production under field conditions. The benefits arising from the foliar application of micronutrient-based zinc oxide fertiliser were compared with those from the titanium dioxide plant-growth enhancer. Both the zinc oxide (ZnO) and titanium dioxide (TiO₂) were delivered by foliar application in nano-size at a concentration of 2.6 mg·L⁻¹. The foliar-applied nanoparticles (NPs) had good crystallinity and a mean size distribution under 30 nm. …

Age, Growth, And Movement Dynamics Of Arctic Cod (Boreogadus Saida) In The Chukchi And Beaufort Seas, Alyssa Frothingham

Fisheries

Arctic Cod (Boreogadus saida) dominates fish assemblages in the Arctic and provides a valuable food source to upper trophic level predators. Little is known about several important facets of its biology and ecology in the Pacific Arctic, including in the Chukchi and Beaufort seas. The physical connectivity of these two biologically and hydrologically unique seas provides an excellent opportunity to explore differences in Arctic Cod life history characteristics such as age, growth, and movement dynamics in these two adjacent areas. To establish a current benchmark of Arctic Cod life history and movement characteristics for the Pacific Arctic, Arctic Cod otoliths …

Is Small Hydropower Beautiful? Social Impacts Of River Fragmentation In China’S Red River Basin, Tyler Harlan, Rui Xu, Jun He

Urban and Environmental Studies Faculty Works

Small hydropower (SHP) is promoted as a pro-poor renewable energy source that does not have the negative social impacts of large dams. This article challenges these claims, using data from a household survey in China’s upper Red River Basin. We find that SHP can fragment river systems in ways that reduce irrigation water availability, provoke changes to agricultural practices, and negatively impact river health. These social impacts of river fragmentation mainly occur in villages situated between a plant’s intake and outflow. The frequency of plant water diversions due to continued generation in the dry season significantly predicts all social impacts; …

Audience Influence On The Composition, Revision And Interpolation Of Traditional Irish Ballad Narrative, Seán Ó Cadhla

Doctoral

The following thesis critically examines the essential thematic malleability of traditional Irish song narrative, with particular focus on the penetrative influence of the audience on both composer and performer alike. Such narrative fluidity is specifically examined within the context of works narrating attested historical events, output which could be reasonably assumed to adhere to factual and chronological consistency. The research concludes that the audience continuously exerts a powerful cultural influence on the performance space, and further demonstrates the considerable extremes that both composers and singers will routinely embrace in order to satisfy the constantly shifting demands of their audiences, even …

The Role Of Cost, Scale, And Property Attributes In Landowner Choice Of Stormwater Management Option., W. Bowman Cutter, Alexander Pusch

Pomona Economics

Cities throughout the world are experimenting with Low Impact Development (LID) strategies to replace ecosystem services degraded by urbanization. Stormwater management may need both centralized/publicly-managed infrastructure and decentralized provision by landowners. For landowners to participate in these programs they will need some latitude in the choice of techniques and siting. However, these landowner choices will affect the bundle of ecosystem services provided (such as infiltration, aesthetics, pollution filtering, and others) as well as their spatial distribution. We studied the Santa Monica (CA) stormwater regulations that require stormwater management on a large portion of development and redevelopment but allow a significant …

Annotated Checklist Of The Bryophytes Observed At The Gordon Natural Area West Chester University, Pa) 2007-2020. Version I, Nur Ritter

Gordon Natural Area Baseline Plant Survey Documents

Summary Data Number of Taxa: 35 Species, in 28 Genera, 23 Families, and 12 Orders. Description The bryophytes are an informal group that is composed of three divisions of non-vascular plants: the liverworts, hornworts, and mosses. Of these, the mosses are the most familiar to most people, but the three groups are similar in appearance, and differ only in their reproductive structures. All bryophytes lack specialized tissues for transporting resources (i.e., vascular tissue); hence, they are characteristically small in stature. Additionally, bryophytes do not produce flowers or seeds; rather, reproduction is through spores. Bryophytes have received relatively little investigation at …

Annotated Checklist Of Invertebrate Species Observed At The Gordon Natural Area (West Chester University, Pa) 2007-2020. Version I, Nur Ritter

Gordon Natural Area Biodiversity Studies Documents

Summary Data Number of Taxa: 250 Species, in 170 Genera, 113 Families, and 33 Orders. Description As with some of the other biotic groups, the research pattern for invertebrates at the GNA might best be described as ‘intermittent.’ Former WCU professor Win Fairchild and his students conducted research on aquatic invertebrates in Plum Run, both inside and outside of the boundaries of the GNA. To date, the only data from that work that we’ve been able to obtain are from the 2007 MS thesis of Danielle DiFederico. Since that time, the only ‘directed’ invertebrate research at the GNA has been …

Annotated Checklist Of The Lichens Observed At The Gordon Natural Area (West Chester University, Pa) 2018—2020 (Version I), Nur Ritter

Gordon Natural Area Biodiversity Studies Documents

Description Lichen research at the Gordon is in it’s infancy. At this time, no faculty members or students have undertaken any directed lichen research. Hence, the only GNA lichen data come from observations from GNA staff, augmented by observations posted on iNaturalist (www.inaturalist.org). As with the bryophytes and fungi from the Gordon, there are numerous photos of unidentified lichens awaiting determination. The checklist was compiled from Gordon Natural Area (GNA) Staff fieldwork from 2018 to 2020. The checklist contains 31 species in 23 Genera, 14 Families, and 7 Orders. This number of species likely only represents a very small portion …

Annotated Checklist Of The Avian Species Observed At The Gordon Natural Area (West Chester University, Pa) 2004-2020. Version Ix. Data From Ebird (Through 7/20/2020) And From The 2004 West Chester Bird Club Survey Of The Gna.Ersion Ix., Nur Ritter, Josh R. Auld

Gordon Natural Area Bird Survey Documents

Summary Data Number of Surveys: 108 'Site Visits' by 28 Birders. Note: this does not count the birders who participated in the 2004 West Chester Bird Club Survey as they were not identified on the species checklist. Number of Taxa: 125 Species, in 86 Genera and 38 Families. Abundances The color of each month's 'box' represents the average number of individuals observed during all surveys during that month (see key at the bottom of the page).

Annotated Checklist Of The Mammal Species Observed At The Gordon Natural Area West Chester University, Pa) 2011-2020. Version I, Nur Ritter

Gordon Natural Area Biodiversity Studies Documents

Summary Data Number of Taxa: 12 Species, in 12 Genera, 9 Families, and 5 Orders. Description No formal investigations of the mammals of the GNA have been conducted. And, until 2016, no system was in place for tracking annual observations of mammal species. Hence, this checklist represents a somewhat haphazard collection of data. GNA staff observations from 2016 onwards represent a significant portion of the data. These observations have been augmented by data from various reports and from photos from the GNA that were posted to Facebook. Status/Threats IUCN Status: Data are from the IUCN Red List of Threatened Species …

Annotated Checklist Of The Fish Species Observed At The Gordon Natural Area (West Chester University, Pa) 1997-2019. Version I, Nur Ritter

Gordon Natural Area Biodiversity Studies Documents

Summary Data Number of Taxa: 14 Species, in 13 Genera, 6 Families, and 5 Orders. Description Investigation of the ichthyofauna (i.e., fish) of the GNA began has a fairly long-history, but has been sporadic and the findings have been poorly archived. The earliest known research was undertaken by former WCU Biology Professor Win Fairchild. Regrettably, we only have his data from a single study (Butler & Fairchild 2005). WCU graduate student Danielle DiFederico (one of Win Fairchild's students) conducted her Master's research in Plum Run in the early 2000. Following this, there was a long fallow period (with just a …

An Analysis Of Irrigation Policy In The Mississippi Delta, Brooklyn Mooney

Honors Theses

This thesis aims to provide a sustainable irrigation alternative that could be easily adopted by farmers in the Mississippi Delta in order to improve water resource management. The Mississippi Alluvial Valley Aquifer, the groundwater system that lies under the Mississippi Delta, is being depleted at rapid rates due to industrial farming and unsustainable, outdated irrigation methods. The intent of this research is to evaluate the water scarcity problem in the Mississippi Delta by assessing water extraction rates and the progression of agriculture in the region. Then, various irrigation methods will be evaluated before a final suggestion is made. Through extensive …

Evaluating The Biological Effects And Safety Of Exposure To Low, Putatively Safe Concentrations Of The Common Pesticide Chlorpyrifos Using An Anuran Model, Sara Mcclelland

Electronic Theses and Dissertations

In the US, over 1.1 billion pounds of pesticides are applied annually. Unfortunately, pesticides contaminate natural habitats affecting animal health. Chlorpyrifos (CPF) is an organophosphorous insecticide that contaminates surface waters. Few studies have assessed the impacts of CPF at low, ecologically realistic doses. I aimed to test the effects of low dose CPF exposures on biological parameters including body morphology, hormone levels, and brain development in Northern Leopard Frogs (Lithobates pipiens), a common vertebrate model. To determine if CPF exposure has direct impacts or indirectly impacts animals through the disruption of the food web, I examined CPF exposure …

The Effects Of Air Pollution On School Attendance In The United States, Debanhi G. Alrich

Theses and Dissertations

This study employs pooled OLS and fixed effect regressions to examine the effects of ambient air pollution on self-reported school attendance in the 423 most populous counties in the United States. Information from the U.S. Census’ American Community Survey’s annual estimate is compared against county-level data for 14 common air pollutant variables. When making this comparison for the general population, we find statistically significant results for only one pollutant: ozone. We find further significant effects for the presence of ozone when respondents are grouped by race/ethnicity and by poverty ratio, indicating that effects of pollution, like many other social ills, …

Paradox In The Bayou: Development And Displacement In America’S Wetlands, Allison Oliver Haertling

LSU New Orleans Theses and Dissertations

The bayou communities situated at the southern ends of Terrebonne Parish, Louisiana possess a rich and uniquely diverse cultural heritage. However, economic factors, combined with environmental issues such as land loss from oil and gas dredging, subsidence, and rising seas, have spurred significant migration “up the bayou” in recent decades, threatening the loss of these cultures and leaving behind a population that is growing increasingly more vulnerable. This study investigates the current and anticipated social, physical and fiscal impacts of persistent land loss and population decline on lower Terrebonne Parish, as well as planning strategies for maintaining existing infrastructure and …

Sociopolitical Silos: Environmental Views And The Multiplicative Effect Of Same-Party Friends, Lawrence C. Hamilton, Joel Hartter, Curt Grimm

Faculty Publications

Analysis of climate and other environmental questions on three regional survey projects conducted over 2017–2020 (9,000+ interviews) elaborate on the well-known importance of political factors by adding support for three newer propositions. First, strength of political identification predicts climate-change views within the ranks of conservatives but not within ranks of liberals, evidence that conservatives’ climate-change views are more politically determined. Second, factor analysis suggests that climate-change beliefs meet statistical criteria for being an indicator of sociopolitical identity, alongside the traditional indicators of ideology and party, or the newer one of Trump support. This result calls for caution interpreting models that …

Evaluation Of Benthic Fish Communities In The Clinch And Duck Rivers As Habitat Indicators For The Endangered Pygmy Madtom, Noturus Stanauli, William G. Wells, Hayden T. Mattingly

Southeastern Fishes Council Proceedings

Identifying which species are associated with a specific endangered species can inform conservation managers about potential community associations and novel localities. The benthic fish community associated with the Pygmy Madtom (Noturus stanauli) in the Duck River has been documented through Index of Biotic Integrity (IBI) work at sites where the Pygmy Madtom has occurred by the Tennessee Valley Authority (TVA). To complement the Duck River data, we gathered benthic fish community data associated with the Pygmy Madtom in the Clinch River. We used Pflieger’s metrics of constancy and fidelity to evaluate fish associations with the Pygmy Madtom. We …

Gas Component Transport Across The Soil-Atmosphere Interface For Gases Of Different Density: Experiments And Modeling, L. M. Bahlmann, K. M. Smits, K. Heck, E. Coltman, R. Helmig, I. Neuweiler

Civil Engineering Faculty Publications - Archive

We investigate the influence of near-surface wind conditions on subsurface gas transport and on soil-atmosphere gas exchange for gases of different density. Results of a sand tank experiment are supported by a numerical investigation with a fully coupled porous medium-free flow model, which accounts for wind turbulence. The experiment consists of a two-dimensional bench-scale soil tank containing homogeneous sand and an overlying wind tunnel. A point source was installed at the bottom of the tank. Gas concentrations were measured at multiple horizontal and vertical locations. Tested conditions include four wind velocities (0.2/1.0/2.0/2.7 m/s), three different gases (helium: light, nitrogen: neutral, …

Assessing Undergraduate Sustainability Knowledge At California Polytechnic State University, Elysa Briens

Master of Science in Environmental Sciences and Management Projects

Sustainability education has become an important focus of many higher education institutions (HEIs), with the inclusion of many sustainability-related learning objectives for undergraduate students. As sustainability is a new, rising discipline, an increasing number of HEIs have made efforts to assess their teaching and learning effectiveness. However, most assessments fall short in determining the relationship between sustainability curriculum and the impacts on leaning outcomes. Therefore, this study aims to assess the impact of academic setting, specifically of a structured sustainability curriculum, on undergraduate sustainability knowledge, as well as analyze the implications of perceived barriers and opportunities to implementing sustainability into …

Determinants Of The Carbon Footprint Of German Swimmers 2020., Ann-Marie Muehlbauer

Master's Theses

The current climate situation is placing our planet and future generations at risk, which demonstrates the urgency to combat climate change and conduct research to support this effort. Calculating the carbon footprint of active sport participation represents an important opportunity to conduct additional research. This study examined the environmental attitudes and practices of swim club members in Germany. The study had three goals: First, to calculate the total and partial carbon footprint of German swimmers; second, to understand how sport organizations induce participants to engage in pro-environmental behavior; and third, to analyze various factors associated with carbon footprint, such as …
