A Historical Ecology Of Aridland Springs In Desert National Wildlife Refuge, Nuwu/Nuwuvi (Southern Paiute/Chemehuevi) Ancestral Territory, Nevada, Yarrow Sarah Valentine Geggus Dec 2020

A Historical Ecology Of Aridland Springs In Desert National Wildlife Refuge, Nuwu/Nuwuvi (Southern Paiute/Chemehuevi) Ancestral Territory, Nevada, Yarrow Sarah Valentine Geggus

Dissertations and Theses

Aridland springs are among the most threatened ecosystems in the world. Vital to desert ecologies and Indigenous cultures, these complex and individualistic ecosystems have layered histories. To inform management in the changing landscape of Desert National Wildlife Refuge, a 1.6 million acre protected area in Southern Nevada, I conducted a historical ecology study of a sample of ten upland springs. Through a six-part interdisciplinary methodology including interviews, archaeological survey, botanical survey, and archival research, I summarize findings into three broad eras: the Nuwu/Nuwuvi pre-Contact Era, the Settler Era, and the U.S. Fish and Wildlife Service Era.

For millennia, Nuwu/Nuwuvi drank …


Are Giant Pandas (Ailuropoda Melanoleuca) Averse To Inequity?, Miranda R. Trapani Dec 2020

Are Giant Pandas (Ailuropoda Melanoleuca) Averse To Inequity?, Miranda R. Trapani

Theses and Dissertations

Inequity aversion, a negative response to situations of unequal reward distribution, is a cognitive trait usually seen in social species. This capacity is thought to regulate cooperative relationships in intelligent, cognitively flexible animals. Giant pandas are a unique case in that wild populations are characterized as nonsocial, however captive populations are socially housed until sexual maturity. This allows for the study of a nonsocial species in a social context and thus the assessment of socio-cognitive flexibility across evolutionarily distant taxa. Here, we assessed whether the giant panda (Ailuropoda melanoleuca) displays inequity aversion by testing ten juveniles living at …


The Sea Will Rise, Barbuda Will Survive: Environment And Time Consciousness, Sophia Perdikaris Dec 2020

The Sea Will Rise, Barbuda Will Survive: Environment And Time Consciousness, Sophia Perdikaris

School of Global Integrative Studies: Faculty Publications

In this article, we examine the link between environmental consciousnesses and time consciousness. We argue that the way people think about time shapes their experience of climate change threats. We contrast western hegemonic concepts of time—the Gregorian Calendar, the Dooms Day Clock, linear time—with the way Barbudans of Antigua and Barbuda, an island nation in the Caribbean experience time—cyclical, through boom and bust cycles. We found that this boom and bust framework was indeed supported by climate change and weather experiences on the island—hurricanes, droughts, changes in the lagoons—as well as economic experiences—cargo boat delays bringing supplies, paycheck delays. By …


Race And Ethnic Variation In College Students’ Allostatic Regulation Of Racism-Related Stress, Jacob E. Cheadle, Bridget J. Goosby, Joseph C. Jochman, Cara Tomaso, Chelsea B. Kozikowski Yancey, Timothy D. Nelson Nov 2020

Race And Ethnic Variation In College Students’ Allostatic Regulation Of Racism-Related Stress, Jacob E. Cheadle, Bridget J. Goosby, Joseph C. Jochman, Cara Tomaso, Chelsea B. Kozikowski Yancey, Timothy D. Nelson

Department of Sociology: Faculty Publications

Racism-related stress is thought to contribute to widespread race/ ethnic health inequities via negative emotion and allostatic stress process up-regulation. Although prior studies document racerelated stress and health correlations, due to methodological and technical limitations, they have been unable to directly test the stress-reactivity hypothesis in situ. Guided by theories of constructed emotion and allostasis, we developed a protocol using wearable sensors and daily surveys that allowed us to operationalize and time-couple self-reported racism-related experiences, negative emotions, and an independent biosignal of emotional arousal. We used data from 100 diverse young adults at a predominantly White college campus to assess …

Publications and Research

Comparisons of mammalian gut microbiota across different environmental conditions shed light on the diversity and composition of gut bacteriome and suggest consequences for human and animal health. Gut bacteriome comparisons across different environments diverge in their results, showing no generalizable patterns linking habitat and dietary degradation with bacterial diversity. The challenge in drawing general conclusions from such studies lies in the broad terms describing diverse habitats (“wild”, “captive”, “pristine”). We conducted 16S ribosomal RNA gene sequencing to characterize intestinal microbiota of free-ranging sympatric chimpanzees and gorillas in southeastern Cameroon and sympatric chimpanzees and gorillas in a European zoo. We conducted …

Scholarship and Professional Work - LAS

Understanding how biodiversity responds to urbanization is challenging, due in part to the single-city focus of most urban ecological research. Here, we delineate continent-scale patterns in urban species assemblages by leveraging data from a multi-city camera trap survey and quantify how differences in greenspace availability and average housing density among 10 North American cities relate to the distribution of eight widespread North American mammals. To do so, we deployed camera traps at 569 sites across these ten cities between 18 June and 14 August. Most data came from 2017, though some cities contributed 2016 or 2018 data if it was …


Fire, Native Ecological Knowledge, And The Enduring Anthropogenic Landscapes Of Yosemite Valley, Douglas Deur, Rochelle Bloom Nov 2020

Fire, Native Ecological Knowledge, And The Enduring Anthropogenic Landscapes Of Yosemite Valley, Douglas Deur, Rochelle Bloom

Anthropology Faculty Publications and Presentations

Yosemite Valley is a place with rich and enduring traditions of Indigenous Ecological Knowledge, manifesting in specific management practices that, in turn, leave discernible imprints upon the natural landscape. Historically, the Native American inhabitants of Yosemite Valley have employed a variety of techniques that materially enhance the availability of culturally preferred plant communities. This chapter identifies specific techniques that appear consistently in the oral traditions and written historical accounts of the valley. These methods included anthropogenic burning, pruning and coppicing, clearing underbrush beneath trees, hand eradication (“weeding”) of certain competing species, selective harvesting, smoking, “knocking” of dead wood from the …

Trail Impact Monitoring In Forest Park, James Mitchell Oct 2020

Trail Impact Monitoring In Forest Park, James Mitchell

Environmental Science and Management Professional Master's Project Reports

Forest Park is an appropriately named 5,200 acre natural area located in northwest Portland, Oregon. A recent study estimated park usage near half a million annual visits and found "trails" to be the park’s most highly valued feature. Unfortunately, many trails were not designed for such traffic as evidenced by slipping hazards, erosion and other ecological impacts. In response to these observations, I partnered with Portland Parks & Recreation to conduct an objective trail impact assessment prescribed by the Forest Park Natural Resource Management Plan. I modified methods from past studies to expand on a recently completed trail condition class …


Book Review: Blue Infrastructures: Natural History, Political Ecology And Urban Development In Kolkata, Dana E. Hellman, Melissa Haeffner Oct 2020

Book Review: Blue Infrastructures: Natural History, Political Ecology And Urban Development In Kolkata, Dana E. Hellman, Melissa Haeffner

Environmental Science and Management Faculty Publications and Presentations

What role does a river play in shaping urban justice and resilience? Jenia Mukherjee tackles this provocative question with an equally provocative answer: rivers are critical infrastructures with biophysical and social histories, both of which inform their physical condition and socio-ecological assets. In Blue Infrastructures, Mukherjee masterfully illuminates the intersection of materiality and history in the urban environment, exploring its implications for a just and resilient future city. Tracing the uses and evolution of Kolkata's “blue infrastructures”—rivers, wetlands, seas, etc.—from the colonial period to the present, Mukherjee's analysis addresses a pressing question in this era of the Urbanocene: How …


Homicide And Drug Trafficking In Impoverished Communities In Brazil, Elenice De Souza De Souza Oliveira, Braulio Figueiredo Alves Da Silva, Flavio Luiz Sapori, Gabriela Gomes Cardoso Sep 2020

Homicide And Drug Trafficking In Impoverished Communities In Brazil, Elenice De Souza De Souza Oliveira, Braulio Figueiredo Alves Da Silva, Flavio Luiz Sapori, Gabriela Gomes Cardoso

Department of Justice Studies Faculty Scholarship and Creative Works

Many studies demonstrate that homicides are heavily concentrated in impoverished neighborhoods, but not all socially disadvantaged neighborhoods are hotbeds of violence. Conducted in Belo Horizonte, Brazil, this study hypothesizes that the association between high rates of homicide and impoverished areas is influenced by the emergence of a specific type of street drug-dealing common to favelas (slums). The study applies econometric techniques to police data on homicides and drug arrests from 2008 to 2011, as well as 2010 Census data, to test its hypothesis. The findings provide insight into the development of crime prevention policies in areas of high social vulnerability.


Reframing Native Knowledge, Co-Managing Native Landscapes: Ethnographic Data And Tribal Engagement At Yosemite National Park, Rochelle Bloom, Douglas Deur Sep 2020

Reframing Native Knowledge, Co-Managing Native Landscapes: Ethnographic Data And Tribal Engagement At Yosemite National Park, Rochelle Bloom, Douglas Deur

Anthropology Faculty Publications and Presentations

Several Native American communities assert traditional ties to Yosemite Valley, and special connections to the exceptional landmarks and natural resources of Yosemite National Park. However, tribal claims relating to this highly visible park with its many competing constituencies—such as tribal assertions of traditional ties to particular landscapes or requests for access to certain plant gathering areas—often require supporting documentation from the written record. Addressing this need, academic researchers, the National Park Service and park-associated tribes collaborated in a multi-year effort to assemble a comprehensive ethnographic database containing most available written accounts of Native American land and resource use in Yosemite …


Examining The Intersection Of Environmental Justice, Chronic Disease, And Pandemics; How A Mobile Health App Could Improve Health Outcomes And Inform Policy, Jessica Snow Aug 2020

Examining The Intersection Of Environmental Justice, Chronic Disease, And Pandemics; How A Mobile Health App Could Improve Health Outcomes And Inform Policy, Jessica Snow

Master's Projects and Capstones

The purpose of this paper is to analyze the intersection of environmental justice, chronic disease and illness, and pandemics. The inequitable distribution of polluting factories, landfills, and hazardous waste sites have been a long-standing concern in the field of environmental justice. Local zoning codes and land use policies have been tools for segregating people and concentrating pollution in low-income communities and communities of color. Many studies have found that pollution varies among racial and minority groups, and the burden of pollution is not one that is evenly shared. Communities of color and low income communities are disproportionately affected by air …


Area-Level Landfill Density And Asthma Prevalence In Urban Texas Areas, Jessica Meighan Herrin Aug 2020

Area-Level Landfill Density And Asthma Prevalence In Urban Texas Areas, Jessica Meighan Herrin

Dissertations & Theses (Open Access)

Environmental exposures, especially air pollutants, pose a threat for an increase in asthma prevalence. In particular, hydrogen sulfide (H2S) gas can cause severe health effects closely resembling asthmatic symptoms. Ambient concentrations of H2S gas correlates with the amount of solid waste found in landfills. The potential for adverse health risks associated with H2S emitted from landfills is of concern for those populations living in close proximity to landfills. Asthma is one of the adverse health effects that can occur due to H2S exposure. However, there is a lack of detailed studies characterizing possible associations between the density of landfills and …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Smartphone based self-tracking fitness applications (apps) like Strava are increasingly becoming a part of recreation experiences in parks and protected areas (PPAs). Recreation research has employed smartphone GPS tracking (SGT) and volunteered geographic information (VGI) to study visitor behavior in PPAs, but little is understood about how smartphones or fitness apps affect visitor perceptions and behavior during their experience.

The first chapter of this thesis is a literature review of recreation survey and behavior research, social-psychology and technology use theory, gamification, and mountain bike social science and recreation-ecology research. The second chapter is formatted for submission to the Journal of …


Sex Differences In Age-Related Disease, Matthew R. Schwartz Jul 2020

Sex Differences In Age-Related Disease, Matthew R. Schwartz

Anthropology ETDs

Life history theory posits the evolution of sex-biased traits through asymmetries in the costs of reproduction. The research presented here evaluated the downstream effects of sex-biases in two age-related disease profiles: tooth loss, in which females exhibit a higher disease burden, and melanoma, in which females have a survival advantage.

Among the Tsimane, a natural fertility population of forager-horticulturalists with a high lifetime fertility and no access to oral healthcare, females lose more than males and around half a tooth per child. Parity accounts for 1.2\% of variation in tooth loss within females, but no variation in tooth loss in …

This article aims to alert the medical community and public health authorities to accumulating evidence on health benefits from sun exposure, which suggests that insufficient sun exposure is a significant public health problem. Studies in the past decade indicate that insufficient sun exposure may be responsible for 340,000 deaths in the United States and 480,000 deaths in Europe per year, and an increased incidence of breast cancer, colorectal cancer, hypertension, cardiovascular disease, metabolic syndrome, multiple sclerosis, Alzheimer's disease, autism, asthma, type 1 diabetes and myopia. Vitamin D has long been considered the principal mediator of beneficial effects of sun exposure. …


Using Soil Geospatial Properties And Environments To Explore Microbial Diversity, Sharon Faye Smith Jul 2020

Using Soil Geospatial Properties And Environments To Explore Microbial Diversity, Sharon Faye Smith

Graduate Theses and Dissertations

Soil microorganisms help maintain nutrient cycling, control carbon sequestration, impact plant productivity, and influence several soil chemical and physical properties; yet, the processes that control the microbial composition of soil and how environmental changes may affect the composition and activity of these organisms at different scales remains a difficult and intriguing puzzle for soil scientists, ecologists, and modelers. Wetlands are endangered and important ecosystems that provide several services, which are directly linked to soil function. However, few wetland assessments consider the soil environment and microbial ecology. Linking soil microbial community composition and distribution patterns to soil physio-chemical properties would provide …


The Role Of Strategic Governance In Reducing Infant Mortality Under Crisis Conditions, Lynn Christine Finley Jun 2020

The Role Of Strategic Governance In Reducing Infant Mortality Under Crisis Conditions, Lynn Christine Finley

Dissertations and Theses

The infant mortality rate (IMR) in some developing countries has decreased faster than the global average even though these countries lack strong economic growth, good governance, and democracy (often acknowledged precursors to improved health outcomes). What accounts for the improvement of the IMR in the absence of these traditional pathways to health gains? Some scholars suggest that the concept of "strategic governance" might help direct attention to intermediary factors that reduce neonatal deaths in countries that experience crisis conditions. The main objective of this dissertation is to investigate the set of governance practices that have reduced IMR in two such …


Dyslexia Beyond The Word: An Ecological Study Of Specific Reading Disorder, Benjamin T. Carter Jun 2020

Dyslexia Beyond The Word: An Ecological Study Of Specific Reading Disorder, Benjamin T. Carter

Theses and Dissertations

This dissertation discusses the effects of dyslexia on reading behavior and cognition. It does so by first outlining the overall incidence of dyslexia, providing current definitions, giving a history of scientific inquiry and discussing relevant contemporary research. Thirteen different analyses are then discussed (ten a priori and three post-hoc). Individuals with dyslexia were found to have increased fixation duration, first run dwell time, total dwell time, and refixation probability. The dyslexia group was also highly sensitive to lexical predictability. Within the reading network, the BOLD response was depressed in dyslexia during reading in the following regions: the left medial and …


Prehistory Of The Ica-Nazca Littoral, Peru, Patrick Henry Carmichael, Alana Cordy-Collins May 2020

Prehistory Of The Ica-Nazca Littoral, Peru, Patrick Henry Carmichael, Alana Cordy-Collins

Andean Past Special Publications

Maritime resources played a significant economic role in the prehistoric coastal communities of Central and Northern Peru, and, prior to the current study, it was reasonable to assume they were equally important on the South Coast. In the 1980s, researchers postulated that the Nasca culture of the Early Intermediate Period was a state-level society based on inland agriculture, heavily augmented by aquatic foodstuffs gathered and processed at coastal settlements. Carmichael calls this the Nasca Maritime Hypothesis. It envisioned permanent, ocean front towns providing massive amounts of marine resources to inland centers, in exchange for agricultural produce. The research reported here …

Laws Restricting Access To Abortion Services And Infant Mortality Risk In The United States, Roman Pabayo, Amy Ehntholt, Daniel M. Cook, Megan Reynolds, Peter Muennig, Sze Yan Liu

Department of Public Health Scholarship and Creative Works

Objectives: Since the US Supreme Court′s 1973 Roe v. Wade decision legalizing abortion, states have enacted laws restricting access to abortion services. Previous studies suggest that restricting access to abortion is a risk factor for adverse maternal and infant health. The objective of this investigation is to study the relationship between the type and the number of state-level restrictive abortion laws and infant mortality risk. Methods: We used data on 11,972,629 infants and mothers from the US Cohort Linked Birth/Infant Death Data Files 2008–2010. State-level abortion laws included Medicaid funding restrictions, mandatory parental involvement, mandatory counseling, mandatory waiting period, and …

Evaluating Seafood Distribution Channels In The Atlantic Sea Scallop And Northeast Multispecies Groundfish Fisheries, Amanda Fall May 2020

Evaluating Seafood Distribution Channels In The Atlantic Sea Scallop And Northeast Multispecies Groundfish Fisheries, Amanda Fall

Electronic Theses and Dissertations

Federal fisheries policy in the United States aims to balance resource conservation with maximum sustainable use. Catch shares are a quota-based management tool that are being increasingly deployed to achieve this ambitious goal. One perceived benefit of catch shares is that they give fishermen control of their catch so they will have the latitude to pursue the most profitable marketing arrangements. Using a mixed-methods approach, this research seeks to (1) describe and document the different marketing strategies that commercial fishermen in the Northeast Multispecies Groundfish and Atlantic Sea Scallop fisheries are using to sell their catch; and (2) estimate the …

Unconventional gas and oil drilling (UGOD) has increased substantially in the United States for more than a decade. The resultant environmental unsafe air pollution effects of UGOD both locally and regionally have been well documented in the literature. Despite the dramatic increase in unconventional well drilling and the toxicant exposure, the health consequences of UGOD remain largely uncertain. This study assesses the relationship between active wells and healthcare use for respiratory diseases by zip code from 2004 to 2008 in the Barnett shale area of Texas. The first modern shale gas well was drilled in the Barnett shale area of …


Characterizing The Impacts Of The Invasive Hemlock Woolly Adelgid On The Forest Structure Of New England, Peter Brehm Boucher May 2020

Characterizing The Impacts Of The Invasive Hemlock Woolly Adelgid On The Forest Structure Of New England, Peter Brehm Boucher

Graduate Doctoral Dissertations

Climate change is raising winter temperatures in the Northeastern United States, both expanding the range of an invasive pest, the hemlock woolly adelgid (HWA; Adelges tsugae), and threatening the survival of its host species, eastern hemlock (Tsuga canadensis). As a foundation species, hemlock trees underlie a distinct network of ecological, biogeochemical, and structural systems that will likely disappear as the HWA infestation spreads northward. Remote sensing can offer new perspectives on this regional transition, recording the progressive loss of an ecological foundation species and the transition of evergreen hemlock forest to mixed deciduous forest over the course of the infestation. …

Roads are proliferating worldwide at an unprecedented rate, with potentially severe impacts on wildlife. We calculated the extent and potential impacts of road networks across the 1,160,000-km2, 13-country range of the globally endangered tiger (Panthera tigris)—a conservation umbrella species. We found that roads were pervasive, totaling 134,000 km across tiger conservation landscapes (TCLs), even in tiger priority sites and protected areas. Approximately 43% of the area where tiger breeding occurs and 57% of the area in TCLs fell within the road-effect zone. Consequently, current road networks may be decreasing tiger and prey abundances by more than …
