Viewing Bornean Human–Elephant Conflicts Through An Environmental Justice Lens, Elena C. Rubino, Christopher Serenari, Nurzhafarina Othman, Marc Ancrenaz, Fauzie Sarjono, Eddie Ahmad Jan 2020

Viewing Bornean Human–Elephant Conflicts Through An Environmental Justice Lens, Elena C. Rubino, Christopher Serenari, Nurzhafarina Othman, Marc Ancrenaz, Fauzie Sarjono, Eddie Ahmad

Human–Wildlife Interactions

Sabah, on the northeastern corner of Borneo, is concurrently Malaysia’s largest producer of oil palm (Elaeis guineensis) and home to the endangered Bornean elephants (Elephas maximus borneensis; elephants). Concomitantly, Sabah has been experiencing increasing and unsustainable human–elephant conflicts (HECs), which have not been thoroughly investigated from a human dimensions standpoint. To address this void, in March 2019, we conducted semi-structured interviews with 37 villagers located in the Sabah districts of Lahad Datu, Tawau, and Telupid to investigate villager cognitions regarding elephants, behaviors toward elephants, the formal and informal village institutions employed to mediate HECs, and the …

Beavers Alter Stream Macroinvertebrate Communities In Northeastern Utah, Susan E. Washko, Brett B. Roper, Trisha Brooke Atwood Dec 2019

Beavers Alter Stream Macroinvertebrate Communities In Northeastern Utah, Susan E. Washko, Brett B. Roper, Trisha Brooke Atwood

Watershed Sciences Faculty Publications

  1. Understanding changes in macroinvertebrate communities is important because they play a large role in stream ecosystem functioning, and they are an important food resource for fish. Beaver‐induced changes to stream morphology could alter macroinvertebrate communities, which in turn could affect food webs and ecosystem function. However, studies investigating the effects of North American beaver activities on macroinvertebrates are rare in the inter‐mountain west, an area with high potential for beaver‐assisted restoration.
  2. The aim of this study was to quantify differences in the macroinvertebrate community between unaltered segments of streams and within beaver ponds in north‐eastern Utah, U.S.A. We assessed macroinvertebrate …


Gender, Family, And Community Attachment In A New Destination, Erin Trouth Hofmann, Claudia Méndez Wright, Emma Meade Earl Dec 2019

Gender, Family, And Community Attachment In A New Destination, Erin Trouth Hofmann, Claudia Méndez Wright, Emma Meade Earl

Sociology, Social Work and Anthropology Faculty Publications

As new immigrant destinations in the USA have become home to more settled immigrant populations, they are also becoming less male-dominated and attracting more women and families. But this process is occurring unevenly, with some new destinations much more attractive to women than others. The factors that might lead a destination to attract or retain women are not well understood. We draw on interviews with long-time Latin American residents in a non-metropolitan community in Utah with a fairly high proportion of women immigrants to analyze the ways in which gender and other factors relate to community attachment in this specific …


Rural Aging: The Geographic Reach Of Service Access In Utah, Identifying Barriers And Solutions, Alexandra T. Schiwal Dec 2019

Rural Aging: The Geographic Reach Of Service Access In Utah, Identifying Barriers And Solutions, Alexandra T. Schiwal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation includes two studies of rural age-related services in the state of Utah. The first study combines geospatial, demographic data (number of people over 55) and age-related services (hospitals, hospice providers, nursing homes, senior centers, and Areas Agencies on Aging) at the county level and census-tract level to determine localized differences in proportional access to age-related services. Higher and lower proportions are then predicted by contextual factors including rural/urban gradient, economic industry, and broadband access. Results demonstrate that broadband access was significantly associated with higher access to age-related services, but being a retirement destination (increase in people over 65 …


Incorporating Natural Play Spaces Into Elementary Playgrounds For Child Developmental Benefits, Ariel L. Wright Dec 2019

Incorporating Natural Play Spaces Into Elementary Playgrounds For Child Developmental Benefits, Ariel L. Wright

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Play environments are crucial to providing developmental opportunities for children and natural playgrounds provide a developmentally rich play environment. This study compared elementary school playgrounds and nature explore classrooms to determine what natural play spaces can be implemented into an elementary school playground for developmental benefits. The playgrounds were evaluated on safety, ADA requirements and what developmental affordances are encouraged through different play components. A Nature Playground Play Spaces List and handouts were developed, and a playground design exploration was conducted as an example for how the play spaces list can be used and to show what benefits can be …


Modeling Lake Temperature Response To Climate Change In The Alaskan Arctic, Thomas Balkcom Dec 2019

Modeling Lake Temperature Response To Climate Change In The Alaskan Arctic, Thomas Balkcom

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This thesis study focuses on simulating lake temperature and ice duration for four lakes at the Arctic Long-Term Ecological Research site, near the Toolik Field Station in Alaska. Model projections were driven by the representative global climate model outputs under different carbon emission scenarios. Results show that my simple lake model can reproduce historical lake temperature and ice duration observations, indicating the reliability of the model for future projections. Model projections show that JuneSeptember lake temperatures would increase by 4.3-5.8 °C from the historical period with most progressive carbon emission scenarios, but by 0.7-2.2 °C in the conservative scenarios. Results …


Gender And Social Acceptance Of Immigrants In A New Destination Site, Emma Meade Earl Dec 2019

Gender And Social Acceptance Of Immigrants In A New Destination Site, Emma Meade Earl

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In this article, I draw on secondary interview data with LatinX immigrants in Cache Valley, Utah, an emerging new destination site in the Inter-Mountain West. While immigrants are drawn to new destinations by employment opportunities, quality of life, or low cost of living, they face many challenges in integrating socially into fairly homogenous communities, which can be particularly challenging for immigrant women. This thesis analyzes the ways in which gender affects social integration in the specific cultural and demographic context of Cache Valley. Using interviews with 16 men and women, I examine gender differences in perceptions of the community, experiences …


Technology In Parenting Programs: A Systematic Review And Pilot Study Of An App-Based Intervention For Latinx Families, Samantha M. Corralejo Dec 2019

Technology In Parenting Programs: A Systematic Review And Pilot Study Of An App-Based Intervention For Latinx Families, Samantha M. Corralejo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Technology and psychological treatments have increasingly been used together to increase the reach of psychotherapy and potentially reduce treatment costs. This research focused on how technology has been used to deliver or facilitate treatments focused on behavioral parent training. Behavioral parent training is a research-supported method of improving parenting skills and child behavior. We first reviewed any existing research on the topic, and found that treatments that used technology to teach parenting skills were generally successful at improving parent and child behavior. The review also identified many research questions that have yet to be answered about the cost of such …


Assessing The Impacts Of Laep Extension At Usu: Development Of A Model Framework, Jason G. Parkinson Dec 2019

Assessing The Impacts Of Laep Extension At Usu: Development Of A Model Framework, Jason G. Parkinson

Over several decades, USU’s Landscape Architecture and Environmental Planning (LAEP) Department and Extension specialists have engaged Utah’s rural communities through several design-based outreach activities. These activities are intended to benefit both community partners interested in learning how design can positively impact the community in tangible ways, and students, who are given the opportunity to engage with real-world projects. This study documents, evaluates, and assesses outcomes of community engagement projects undertaken by LAEP Extension to better understand the program’s impact over time and come up with approaches that will enhance the impact of future community engagement projects.

This research develops a …


Enteric Methane And Nitrogen Emissions In Beef Cattle Grazing A Tannin-Containing Legume Relative To Feedlot And Traditional Pasture-Based Production Systems, Raúl David Guevara Ballesteros Dec 2019

Enteric Methane And Nitrogen Emissions In Beef Cattle Grazing A Tannin-Containing Legume Relative To Feedlot And Traditional Pasture-Based Production Systems, Raúl David Guevara Ballesteros

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Beef cattle production is highly criticized because of the high use of land and water resources, and by the pollution (e.g., the gas methane in a cow’s breath and nitrogen in urine) produced by cows fed in feedlots. In contrast to feedlots diets and grasses, some plants (e.g., legumes) contain bioactive compounds (condensed tannins) that reduce pollution and enhance animal nutrition. In my research, I observed that cows grazing a tannin-containing legume (birdsfoot trefoil; BFT) had methane emissions similar to cows fed a feedlot ration with comparable weight gains. Cows in the BFT treatment gained more weight than cows grazing …


The Farm As Place In A Changing Climate: Capturing Women Farmers' Experiences In Idaho, United States And Victoria, Australia, Tagen Towsley Baker Dec 2019

The Farm As Place In A Changing Climate: Capturing Women Farmers' Experiences In Idaho, United States And Victoria, Australia, Tagen Towsley Baker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In Australia and the US, women play a vital role in the agricultural sector. However, historically farmwomen’s contributions to agriculture as well as their individual knowledge and social resilience to stressors like climate and climate change have been unrecognized and rendered invisible. Drawing on interdisciplinary scholarship from geography and the humanities, this dissertation explores the farm as place in a changing climate, drawing on women farmers’ experiences, under three distinct themes: identity, place, and photography. The dissertation research includes three distinct parts. First, incorporating non-fiction writing and photography, I explore my agricultural and religious heritage, as well as familial connections …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Communicating the risks related to extreme heat is important and essential for saving lives. This study looks at how tourists think about extreme heat in a hot and dry environment. It looks at relationships between an individual’s local climate, their thoughts about the current weather conditions, and demographics. The results from this study are intended to help tourist agencies, emergency managers and emergency planners, and policymakers in creating and carrying out communication strategies for extreme heat.

Thoughts about and physical responses to weather are different for everyone and shaped by personal experiences. How one thinks and feels about the weather …


Current And Historic Visitor Experiences In Coastal Alaskan Wilderness: Visitor Motivations And Experience Quality In Glacier Bay National Park & Preserve, Gabriella R. Furr Dec 2019

Current And Historic Visitor Experiences In Coastal Alaskan Wilderness: Visitor Motivations And Experience Quality In Glacier Bay National Park & Preserve, Gabriella R. Furr

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Visitors to parks and protected areas (PPAs) engage in a variety of activities and choose different modes of travel, especially when the location itself has few limitations, such as open-water settings with relatively few backcountry visitors. Managers must understand why visitors are recreating in a particular place and the quality of their experiences in order to offer appropriate and meaningful opportunities. This study seeks to better understand visitor motivations (the “why”), to develop and measure effective indicators for evaluating the quality of visitor experiences, and to contextualize these findings with a unique investigation of historical Glacier Bay National Park data. …


Organizational Capacity Of Nonprofit Organizations In Rural Areas Of The United States: A Scoping Review, Jayme E. Walters Nov 2019

Organizational Capacity Of Nonprofit Organizations In Rural Areas Of The United States: A Scoping Review, Jayme E. Walters

Sociology, Social Work and Anthropology Faculty Publications

Rural America is facing a plethora of problems related to poverty, crime, health, and education. Nonprofit organizations serve a vital role in rural communities by providing services and advocacy to residents. Yet, it is unknown if rural nonprofits have the means to effectively address the complex issues before them. This study examines the results of scoping review which characterizes the state of empirical knowledge regarding the organizational capacity of rural nonprofits in the United States. Fifteen articles from the past decade uncovered challenges and strengths related to organizational capacity, though more research is necessary to inform funders and educators.


Renegotiating Gender Roles And Cultivation Practices In The Nepali Mid-Hills: Unpacking The Feminization Of Agriculture, Kaitlyn Spangler, Maria Elsia Christie Nov 2019

Renegotiating Gender Roles And Cultivation Practices In The Nepali Mid-Hills: Unpacking The Feminization Of Agriculture, Kaitlyn Spangler, Maria Elsia Christie

Environment and Society Student Research

The feminization of agriculture narrative has been reproduced in development literature as an oversimplified metric of empowerment through changes in women’s labor and managerial roles with little attention to individuals’ heterogeneous livelihoods. Grounded in feminist political ecology (FPE), we sought to critically understand how labor and managerial feminization interact with changing agricultural practices. Working with a local NGO as part of an international, donor-funded research-for-development project, we conducted semi-structured interviews, focus group discussions, and participant observation with over 100 farmers in Mid-Western Nepal in 2017. Household structure and headship are dynamic in the context of male out-migration, pushing women to …

A Global View Of Aspen: Conservation Science For Widespread Keystone Systems, Paul C. Rogers, Bradley D. Pinno, Jan Šebesta, Benedicte R. Albrectsen, Guoqing Li, Natalya Ivanova, Dominik Kulakowski, Antonín Kusbach, Timo Kuuluvainen, Simon M. Landhäusser, Hongyan Liu, Tor Myking, Pertti Pulkkinen, Zhongming Wen

Ecology Center Publications

Across the northern hemisphere, six species of aspen (Populus spp.) play a disproportionately important role in promoting biodiversity, sequestering carbon, limiting forest disturbances, and providing other ecosystem services. In many regions, aspen can maintain canopy dominance for decades to centuries as the sole major broadleaf trees in forested landscapes otherwise dominated by conifers. Aspen ecosystems are valued for many reasons, but here we highlight their potential as key contributors to regional and global biodiversity. We begin with an overview of the aspens’ ecological and economic roles. We then present a systematic literature analysis to assess topics of aspen …


Racial Stratification In Self-Rated Health Among Black Mexicans And White Mexicans, Guadalupe Marquez-Velarde, Nicole E. Jones, Verna M. Keith Oct 2019

Racial Stratification In Self-Rated Health Among Black Mexicans And White Mexicans, Guadalupe Marquez-Velarde, Nicole E. Jones, Verna M. Keith

Sociology, Social Work and Anthropology Faculty Publications

How do Mexicans of distinct racial backgrounds fit into the recognized patterns of racial health disparities? We conduct regression analyses using data from the 2000-2017 National Health Interview Survey to determine if Mexicans who self-identify as White or Black have a relative advantage or disadvantage in self-rated health in relation to Non-Hispanic (NH) Whites and Blacks in the U.S. Our results indicate that both Black Mexicans and White Mexicans have a significant disadvantage in relation to NH-Whites while White Mexicans have a slight advantage in relation to both NH-Blacks and Black Mexicans. Overall, our results suggest that studying health outcomes …


Genetic Structure Of Mycoplasma Ovipneumoniae Informs Pathogen Spillover Dynamics Between Domestic And Wild Caprinae In The Western United States, Pauline L. Kamath, Kezia Manlove, E. Frances Cassirer, Paul C. Cross, Thomas E. Besser Oct 2019

Genetic Structure Of Mycoplasma Ovipneumoniae Informs Pathogen Spillover Dynamics Between Domestic And Wild Caprinae In The Western United States, Pauline L. Kamath, Kezia Manlove, E. Frances Cassirer, Paul C. Cross, Thomas E. Besser

Ecology Center Publications

Spillover diseases have significant consequences for human and animal health, as well as wildlife conservation. We examined spillover and transmission of the pneumonia-associated bacterium Mycoplasma ovipneumoniae in domestic sheep, domestic goats, bighorn sheep, and mountain goats across the western United States using 594 isolates, collected from 1984 to 2017. Our results indicate high genetic diversity of M. ovipneumoniae strains within domestic sheep, whereas only one or a few strains tend to circulate in most populations of bighorn sheep or mountain goats. These data suggest domestic sheep are a reservoir, while the few spillovers to bighorn sheep and mountain goats can …

Aspen Bibliography

  1. Ploidy level in plants may influence ecological functioning, demography and response to climate change. However, measuring ploidy level typically requires intensive cell or molecular methods.
  2. We map ploidy level variation in quaking aspen, a dominant North American tree species that can be diploid or triploid and that grows in spatially extensive clones. We identify the predictors and spatial scale of ploidy level variation using a combination of genetic and ground‐based and airborne remote sensing methods.
  3. We show that ground‐based leaf spectra and airborne canopy spectra can both classify aspen by ploidy level with a precision‐recall harmonic mean of 0.75–0.95 and …


Timing Of Invasion By Africanized Bees Coincides With Local Extinction Of A Specialized Pollinator Of A Rare Poppy In Utah, Usa, Amber D. Tripodi, Vincent J. Tepedino, Zachary M. Portman Sep 2019

Timing Of Invasion By Africanized Bees Coincides With Local Extinction Of A Specialized Pollinator Of A Rare Poppy In Utah, Usa, Amber D. Tripodi, Vincent J. Tepedino, Zachary M. Portman

All PIRU Publications

The introduction of exotic species can have profound impacts on mutualisms between native species in invaded areas. However, determining whether a new invader has impacted native species depends on accurately reconstructing the invasion timing. The arrival of Africanized honey bees (AHB) in southern Utah at some point between 1994 and 2011 has recently been implicated in the local extinction of Perdita meconis, a native specialist pollinator of an endangered poppy, Arctomecon humilis. Although AHBs were purportedly first detected in southern Utah in 2008, their presence in nearby Nevada, Arizona, and New Mexico by 1998–2001 suggests that they may …

Ecology Center Publications

PREMISE: Spore-bearing plants are capable of dispersing very long distances. However, it is not known if gene flow can prevent genetic divergence in widely distributed taxa. Here we address this issue, and examine systematic relationships at a global geographic scale for the fern genus Pteridium.

METHODS: We sampled plants from 100 localities worldwide, and generated nucleotide data from four nuclear genes and two plastid regions. We also examined 2801 single nucleotide polymorphisms detected by a restriction site-associated DNA approach.

RESULTS: We found evidence for two distinct diploid species and two allotetraploids between them. The “northern” species (Pteridium aquilinum) has distinct …

A remarkable, large‐amplitude, mountain wave (MW) breaking event was observed on the night of 21 June 2014 by ground‐based optical instruments operated on the New Zealand South Island during the Deep Propagating Gravity Wave Experiment (DEEPWAVE). Concurrent measurements of the MW structures, amplitudes, and background environment were made using an Advanced Mesospheric Temperature Mapper, a Rayleigh Lidar, an All‐Sky Imager, and a Fabry‐Perot Interferometer. The MW event was observed primarily in the OH airglow emission layer at an altitude of ~82 km, over an ~2‐hr interval (~10:30–12:30 UT), during strong eastward winds at the OH altitude and above, which weakened …


South-South Cooperation Or Core-Periphery Contention? Ghanaian And Zambian Perceptions Of Economic Relations With China, Colin Flint Aug 2019

South-South Cooperation Or Core-Periphery Contention? Ghanaian And Zambian Perceptions Of Economic Relations With China, Colin Flint

Political Science Faculty Publications

The geopolitics of development are explored through an examination of development assistance to two African countries as a mechanism of competition between China and the US. The processes of competition include the actions and rhetoric of African leaders. We define a geopolitical context for the agency of political leaders and opinion-makers in Ghana and Zambia. The geopolitical context consists of the structure and dynamics of the world-economy; especially the competition to capture the newest round of innovations and the related need to establish supply chains of raw materials from peripheral countries. By analysing quotes from Ghanaian and Zambian elites we …

Work Experiences Of Rural Social Workers In The United States, Jayme E. Walters, Aubrey E. Jones, Aaron R. Brown

Sociology, Social Work and Anthropology Faculty Publications

Rural social workers face unique challenges and opportunities as they seek to address the needs of rural Americans. Using social media, rural social workers in the U.S. were recruited to describe their characteristics and explore factors related to their job satisfaction, burnout, and organizational commitment. Analyses included univariate descriptive statistics, bivariate correlations, and multiple regression. The sample (N = 192) represented 146 counties in 36 states. Participants tended to be White, female, MSW-degreed direct-service providers. Participants were moderately satisfied with their organizational environments and workloads. Age, being Black, and working in settings other than child welfare were most strongly related …

The Missing Angle: Ecosystem Consequences Of Phenological Mismatch, Karen H. Beard, Katharine C. Kelsey, A. Joshua Leffler, Jeffrey M. Welker

Ecology Center Publications

Climate change leads to unequal shifts in the phenology of interacting species, such as consumers and their resources, leading to potential phenological mismatches. While studies have investigated how phenological mismatch affects wild populations, we still lack studies and a framework for investigating how phenological mismatch affects ecosystems, particularly nutrient cycling.


Environmental Differences Between Migratory And Resident Ungulates—Predicting Movement Strategies In Rocky Mountain Mule Deer (Odocoileus Hemionus) With Remotely Sensed Plant Phenology, Snow, And Land Cover, Benjamin Robb, Qiongyu Huang, Joseph O. Sexton, David C. Stoner, Peter Leimgruber Aug 2019

Environmental Differences Between Migratory And Resident Ungulates—Predicting Movement Strategies In Rocky Mountain Mule Deer (Odocoileus Hemionus) With Remotely Sensed Plant Phenology, Snow, And Land Cover, Benjamin Robb, Qiongyu Huang, Joseph O. Sexton, David C. Stoner, Peter Leimgruber

Wildland Resources Faculty Publications

Migration is a valuable life history strategy for many species because it enables individuals to exploit spatially and temporally variable resources. Globally, the prevalence of species’ migratory behavior is decreasing as individuals forgo migration to remain resident year-round, an effect hypothesized to result from anthropogenic changes to landscape dynamics. Efforts to conserve and restore migrations require an understanding of the ecological characteristics driving the behavioral tradeoff between migration and residence. We identified migratory and resident behaviors of 42 mule deer (Odocoileus hemionus) based on GPS locations and correlated their locations to remotely sensed indicators of forage quality, land cover, snow …

What We (Don’T) Know About Global Plant Diversity, William K. Cornwell, William D. Pearse, Rhiannon L. Dalrymple, Amy E. Zanne

Ecology Center Publications

The era of big biodiversity data has led to rapid, exciting advances in the theoretical and applied biological, ecological and conservation sciences. While large genetic, geographic and trait databases are available, these are neither complete nor random samples of the globe. Gaps and biases in these databases reduce our inferential and predictive power, and this incompleteness is even more worrisome because we are ignorant of both its kind and magnitude. We performed a comprehensive examination of the taxonomic and spatial sampling in the most complete current databases for plant genes, locations and functional traits. To do this, we downloaded data …
