Island Invasion: The Silent Crisis In Hawaii, Sophia Janssen

Pomona Senior Theses

Keeping out invasive species may, upon first review, seem like a trivial environmental cry from ecologists and deep environmentalists; a belated wish to return to an undeveloped world where nature was pristine. However invasive species create problems that impact all of us and can have far more severe consequences than changing a stunning landscape. These problems are heightened in islands like Hawaii, where the fragile ecosystems have developed over centuries of evolution and adaptation. The introduction of a disease-carrying mosquito can put the people of Hawaii at risk to many vector-born illnesses and create an epidemic, taking human life. The …

Cities around the world have an important role in reducing the negative impacts of climate change through strategic and sustainable urban planning. The purpose of this study is to conduct an introductory analysis of Geldinganes island and its potential and capacity for land development that will support and expand upon the city of Reykjavik’s 2010-2030 municipal plan and 2040 climate neutrality goals. Within this study three proposals for Geldinganes are considered, the current proposal and two new proposals. The lowest development impact proposal for Geldinganes …

He Effects Of Climate Change On Native Icelandic Plants: A Morphometric Analysis, Maia Jones

Independent Study Project (ISP) Collection

This study seeks to evaluate the morphology of three native Icelandic plant species, Alchemilla alpina, Arabidopsis petraea, and Silene uniflora, in order to determine if changing climatic conditions have had an effect on Icelandic vegetation during the twentieth century. I measured herbarium specimens collected during a time period before 1950, and during the period from the late 1960s to the present. Using traditional morphometrics methods, I searched for changes in morphological traits such as plant height, leaf length to width ratio, and leaf size, then performed two-tailed t-tests to analyze the results of the analyses. I found significant changes …

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Science, Advocacy, Policy, Planning: Tools For Advancing Transportation Equity, Garrett S. Mcallister

Graduate Student Portfolios, Professional Papers, and Capstone Projects

The theme of this portfolio is how different tools and approaches can be used for advancing transportation equity. Broadly defined, transportation equity is about fairness in transportation. There are a number of ways this fairness can be assessed. The most common way to assess transportation equity is by looking at the fairness of outcomes, distributed geographically, socially, or even by mode of transportation. Equity can also be defined by the fairness of processes. The first half of the portfolio illustrates some of the problems with the current transportation system and how it is unhealthy (Piece 1) and unjust (Piece 2). …

Integration Of Plastic Recycling Within A Smaller Community: Reducing Plastic Pollution In The Environment, Olivia Palenscar

Independent Study Project (ISP) Collection

The purpose of this research is to bring awareness to plastic pollution and find a way integrate plastic recycling workshops in a smaller community. Plastic pollution is a worldwide issue. Plastic is a versatile material and can be used to make almost anything, which is an attractive trait but the amount of plastic being consumed is alarming and only continues to increase. Plastic essentially never goes away because the degradation of plastic can last hundreds of years. The challenge is to find ways that everyone can recycle plastic because over 90% of plastic does not end up being recycled. Most …

Watered Down: The Challenges Of Managing Water Resources In Montana, Beau E. Baker

Graduate Student Theses, Dissertations, & Professional Papers

Like much of the American West, Montana sits in the cross hairs of climate change. State drought resiliency projects and cooperative watershed management are on the rise in the face of decreased snowpack, early runoff, precipitation variability and lower seasonal stream flows. Population growth, land use practices, recreation and tourism all contribute to pressures on state water supplies.

Montana is faced with the arrival of invasive species that threaten the ecological health of its lakes, rivers and streams. State budget constraints and depressed agency capacity are hurting our ability to fend off these threats. There’s a lack of public education …

Philosophy Bakes No Bread, Babette Babich

Articles and Chapters in Academic Book Collections

Philosophy Bakes No Bread

Far from baking bread, far from practical applicability, philosophy traditionally sought to explain the world, ideally so. Thus, when Marx argued that it was high time philosophy “change the world,” his was a revolutionary challenge. Today, philosophy is an analytic affair and analytic philosophers seek less to explain the world than to squirrel out arguments or, more descriptively, to resolve the minutiae of this or that name problem. Faced with diminishing student demand, analytic philosophers have taken to urging that everyone from primary school students to scientists be required to study (analytic) philosophy. Just so, applied …

Coral Species Distribution And Percent Cover Of Sessile Organisms On Protected And Non-Protected Coral Reefs In Digir, Buga, Dubbir, And Kanir Kinnidup, Guna Yala, Panama, Sarah Paulson

Independent Study Project (ISP) Collection

Coral reefs are the most productive, biodiverse ecosystems in the ocean despite covering only <.5% of the ocean floor. In today’s changing climate, coral reefs face a multitude of threats including ocean warming, coral bleaching, ocean acidification, overfishing, increasing human population, and coral mining, among others. One way to protect coral reefs is to establish a marine protected area to limit damage and contamination. This study aimed to examine coral species distribution as well as percent cover of sessile organisms and substrates including coral, fire coral, algae, and sponges on protected and non-protected reefs in order to attempt to analyze the effect of protection on coral reefs in Guna Yala, Panama. Based on the data collected, protected areas had higher algae cover (P<.01, df=107), lower coral cover (P<.0001, df=138), and a higher relative abundance of corals with a “weedy” life history such as Porites astreoides (P<.05, df=80). The data also showed that uninhabited islands tended to have significantly higher average coral cover (P<.0001, df=146) and lower average algae cover (P<.0001, df=161), as well as lower relative abundance of P. astreoides (P<.01, df=134). When the protected site sampled was compared to an unprotected site that was around the same island, the protected area was found to have higher coral cover (P<.01, df=71) and lower algae cover (P<.05, df=72) than the unprotected area. Ultimately, lack of human population and protected status were found to be positive factors for coral reef health, and future study should be done to further examine the relationship between these two factors.

An Ethnobotanical Examination Of Traditional Medicine In Ngezi Forest Reserve, Tyler Tsang

Independent Study Project (ISP) Collection

Traditional medicine is an important aspect of the both the culture and health of communities worldwide. Ngezi Forest Reserve is a protected area on Pemba Island which is part of the Zanzibar Archipelago. This forest contains a wealth of botanical diversity which includes many species of medicinal plants. Traditional healers (waganga) use these medicinal plants to heal members of the community. Interviews and forest walks with these healers were supplemented by consultations with a botanist to determine medicinal value of the forest and the surrounding areas. In compiling information from 15 healers in the area, 98 species of medicinal plants …

Hydrology And Macroinvertebrates As Biological Indicators- An Integrated Study Of The Río Zamora Watershed, Loja, Ecuador, Isabel Ryde

Independent Study Project (ISP) Collection

Water quality and access is under grave threat in Ecuador, yet remains poorly studied. Macroinvertebrates were used as biological indicators to study water quality around Reserva Natural Madrigal del Podocarpus, Loja Province, Ecuador. Data on macroinvertebrates was combined with hydrologic measurements of stream functions. Macroinvertebrate sampling was conducted from 6 sites within the Upper Río Zamora watershed. Geologic outcrops were observed along several roadcuts and stream banks. Hydrologic data was collected by measuring discharge, elevation change, and finding the highest permanent spring. The EPT index (number of EPT individuals and percentage of EPT individuals) and the BMWP/Colombia Index for macroinvertebrates …

Trends In The Environmental Health Job Market For New Graduates, Jason W. Marion, Timothy J. Murphy Phd, Anne Marie Zimeri Phd

EKU Faculty and Staff Scholarship

The question of whether the job market can support future graduates of environmental health programs remains an important and difficult question for environmental health programs, current and prospective students, parents, and other stakeholders. Our previous report using 2014 data from the U.S. Bureau of Labor Statistics demonstrated anticipated growth and higher than average pay in the profession through at least 2022 for baccalaureate degree holders (Marion & Sinde, 2015). Growth in the profession does not necessarily translate into job availability if the market is saturated with job candidates. While university programs produce graduates, local health departments (LHDs) have suffered tremendous …

The Methane-Oxidizing Capability Of Pumice Biocovers On Icelandic Landfills, Mitchell P. Miller

Independent Study Project (ISP) Collection

Pumice has been shown in laboratory biofilter experiments to improve the oxidation of methane (Pratt et al. 2012, Pratt, Tate, & Deslippe 2012). Pumice biocovers were tested on two Icelandic landfills, Kirkjuferjuhjáleiga and Álfsnes. Seven biocover plots were dug and filled with a 50:50 blend of pumice and native soil. CH4 and CO2 were measured using the static chamber method before and after biocover placement. After one week, the CH4:CO2 ratio was reduced on four of the seven plots, weakly indicating that pumice biocovers may be an effective way to better oxidize landfill methane.

Factors That Determine Civil Action In Opposition To Hydroelectric Development Along The Chiriquí Viejo River In The Chiriquí Province Of Panamá, Nora Sawyer

Independent Study Project (ISP) Collection

Hydroelectric development has increased rapidly throughout Latin America in the late 20th and early 21st centuries (del Mar Rubio et al. 2014). In 2014, Latin America represented 20 percent of the world’s hydropower (del Mar Rubio et al. 2014). It is also the main source of power generation throughout Latin America, accounting for roughly 65 percent of all electricity generated (Wheeler 2012). Within Panamá, significant hydroelectric development has been happening in the Chiriquí province. Local peoples’ dissatisfaction with the actions of the hydropower companies has increased with time, resulting in civilians and organizations taking action in opposition to these companies …

Impact Of Urbanization On Temperature Variation In Big Cities: Measuring Health Risk While Targeting Vulnerable Population, Maryam E. Karimi

Dissertations, Theses, and Capstone Projects

Densely populated cities are experiencing Urban Heat Island (UHI) effects and localized hotspots. Cities, such as New York can form heat islands all year round. This is primarily due to land surface modifications, radiative trapping in urban canyons and lack of cooling through evapotranspiration caused by displaced trees and vegetation. UHI refers to an increase in air and surface temperature in cities compared to surrounding suburban and rural areas. Large scale environmental forcing can cause subdivisions of UHI throughout a city. The combined of environmental forcing effects lead to the formation of hot pockets within the cities at micro-scale. The …

Evaluating Trophic Rewilding As A Conservation Technique, Aaron Sieve

Biology: Student Scholarship & Creative Works

The focus for this paper is to define specifically trophic rewilding, determine its efficacy as a conservation technique, and explore ways to lessen one of its key limitations. Trophic rewilding is the conservation technique whereby an extirpated keystone species or ecosystem engineer is reintroduced into a degraded habitat to restore ecological function by triggering trophic cascades. The technique is evaluated through analysis of the concepts of trophic cascades and ecosystem engineers. Key limitations of trophic rewilding are that a lack of population control in reintroduced may cause issues, that many times not enough is known about trophic cascades to be …

Poison In Pink, Sydney V. Cook

Graduate Student Theses, Dissertations, & Professional Papers

Humans slather, spray, mist, and cleanse their bodies with personal care products like lotion, hairspray, cologne, and shampoo every day. Our cupboards are stocked full of them, but few of us understand what is in those jars and bottles. We trust that if it’s on the shelf at the store, it’s safe. However, this is not always the case, and many personal care products contain chemicals that are harmful to human and environmental health.

My multi-disciplinary Environmental Studies thesis project combines evidenced-based research, interviews, nonfiction narrative, and science communication to create part of a book manuscript intended to educate general …

From Disposable Culture To Disposable People: Teaching About The Unintended Consequences Of Plastics, Sasha Adkins

Antioch University Dissertations & Theses

Plastics, the epitome of disposable culture, pose both a toxicological and a spiritual problem. This dissertation examines plastics at a molecular level using the discourse of endocrine disruption, and at a sociological level using the discourses of eco-theology and environmental justice. Adding to the literature on the adsorption of toxicants to plastic marine debris, I demonstrate that certain types of plastic -- those containing mercaptans, such as styrene butadiene block copolymer -- efficiently concentrate methyl mercury from seawater. Further, samples of polycarbonate contributed mercury to seawater. I propose the term plastic-mediated magnification to describe the phenomenon that plastics, along with …

Reef Fish And Coral Assemblages On Hospital Point And Near Bastimentos Island, Panama, Elaine Shen

Independent Study Project (ISP) Collection

Because worldwide declines coral reef health are of major concern, studying coral reefs through the lens of conservation efforts at local scales is essential for determining and monitoring effective policy measures. In the Bocas del Toro Archipelago, there are conflicts of interest between exploitative rapid tourism development, overfishing practices, and national efforts to conserve the local marine biodiversity. Coral and reef fish species abundance richness, diversity, evenness, and similarity were measured to see how coral and reef fish assemblages changed between protected and unprotected areas. A total of 329 fish and 322.5 square meters of benthos were analyzed using underwater …

Variability Of Lacustrine Sediment Proxy Responses To Late Holocene Climate Change As Modified By Lake Specific Processes: A Review Of Ecological And Geophysical Processes Across Northern And Eastern Iceland, Mallory Mintz

Independent Study Project (ISP) Collection

Consistenly-deposited lake sediments provide some of the highest resolution records of local and global climates in the past, offering the potential to better understand modern climate change in the context of past climate variability. In relating proxies to their respective climate regimes, the environmental cues that the specific proxies reacted to must be isolated from the general noise of possible local influences. In this investigation, biogenic silica (BSi), total organic carbon (TOC), δ13C values, and carbon: nitrogen ratios were analyzed between lakes through northern Iceland, to review possible complicating factors specific to the use of lacustrine proxies in the interpretation …

Investigating Effects Of Climate Change On Glaciers And Proglacial Landscapes In Southeast Iceland: Fluvioglacial Behavior Of Sólheimajökull And Seljavallajökull, Roberta B.C. Miller

Independent Study Project (ISP) Collection

The Seljavallajökull glacier, part of the Eyjafjallajökull glacier system, and Sólheimajökull, part of the Mýrdalsjökull glacier system, are two glaciers that extend into valleys in the southeast part of Iceland. Due to climate warming, both of these glaciers are part of a melting ice cap. They are located nearby to one another, and Sólheimajökull has been extensively studied for its outwash plain sedimentology, retreat history, pro-glacial geomorphology and has been steadily monitored by the Glaciological Society of Iceland. Seljavallajökull has also been monitored by this group, but it has not been studied for sediment profiles and landscape chronology as Sólheimajökull …

The Importance Of Rivers In Protected Areas: Macroinvertebrate Sampling Reveals The Impact Of Humans And Highways On Water Quality, Marie-Claire Harrison

Independent Study Project (ISP) Collection

The water quality and level of contamination of two rivers in a cloud forest ecosystem in the Mejía region of Ecuador, the Tupí River and the Pilatón River were assessed through benthic macroinvertebrate sampling at various sites along the rivers. Many different biological indices were then used to assess water quality at each site. Pollution in the form of grey water, black water, and petroleum negatively impacted the water quality of the both rivers as they pass through the town of La Esperie. Differences in river structure and size also played a role in determining the prevalence of certain benthic …
