Weed Control As A Collective Action Problem: Quantifying Group Effects On Individual Behavior, And Clarifying The Theoretical Frame, Alice Lubeck

Graduate Student Theses, Dissertations, & Professional Papers

Weeds reduce the biodiversity and productivity of agricultural systems, and are a problem both around the world, and in Montana. Weeds are challenging to control because their effective dispersal mechanisms enable cross-boundary colonization, and so managers must engage diverse groups of private landowners. Researchers have recognized weed control is a collective action problem, but there is little research quantifying the role of collective factors on an individual’s decision to control. To fully understand the motivations behind independent weed control, I initiated a study to quantitatively assess different types of landowners and their weed control behaviors, the relationship between collective interest …

Lessons Learned In The Superfund Process: A Guide For Community Advisory Groups, Terri Nichols

Graduate Student Theses, Dissertations, & Professional Papers

Superfund Community Advisory Groups (CAGs) and Technical Advisory Groups, also known as Technical Assistance Groups, (TAGs) can influence the clean-up of hazardous wastes in their communities by providing a forum for diverse community interests and concerns in the federal Superfund clean-up process. These volunteer groups may increase local input and engagement in remediation of hazardous wastes, as well as in the ultimate future of their community, through collaboration with community members, U.S. Environmental Protection Agency staff, and parties responsible for contamination. Yet most CAGs and TAGs struggle within the complex, multi-phase Superfund process. Forming a Superfund advisory group is a …

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 …

Growing Youth Programming At Garden City Harvest Through Participatory Action Research, Hannah B. Oblock

Graduate Student Theses, Dissertations, & Professional Papers

This professional paper presents a program evaluation and strategic plan for the youth development farming programs at Garden City Harvest (GCH), a non-profit in Missoula, Montana, which coordinates community-centered agriculture projects and facilitates sustainable agriculture education. The youth programs, Youth Harvest (YH) and Youth Farm (YF), hire adolescents of 15-18 years of age to work on their urban farms to learn about sustainable agriculture, job readiness skills, and social-emotional well-being. As the organization continues to expand, especially with the addition of a new facility, GCH administration and staff are interested in learning how the programs impact the youth employees and …

Respecting Public Investment: The Problems With Democratic Endorsement As A Criterion For Legitimate Value Influence In Science, Rebecca Korf

Graduate Student Theses, Dissertations, & Professional Papers

Criticism of the value-free ideal has motivated attempts to formulate a criterion for the legitimacy of non-epistemic value influence in science. I argue that this search aims to protect two main components of legitimacy, scientific integrity and justice. While integrity is primary, justice remains important, especially in setting scientific goals. One of the main proposals for setting legitimate goals is to rely on democratic endorsement (Intemann 2015). I critically assess four interpretations of this criterion, finding that all are problematic. I then propose and evaluate three alternative models that seek to better balance respect for the public with scientific expertise.

Meat Reimagined: The Ethics Of Cultured Meat, Valan Anthos

Graduate Student Theses, Dissertations, & Professional Papers

In this paper I explore a relatively new technology that is being developed to try and solve some of the major issues with modern animal agriculture called cultured meat. I cover the short history of this technology and where it is at currently before addressing two different ways of evaluating the ethics of cultured meat. Responding to much of the praise for cultured meat based on consequentialist ethics, I lay out reasons for skepticism and how some of these estimates might be overblown due to those people advocating for it being situated in the ideology of ecomodernism. I argue that …

Wilderness Solitude In The 21st Century, Thomas C. Lang

Graduate Student Theses, Dissertations, & Professional Papers

Recent advances in mobile communication technology have led to a decrease in opportunities for individuals to experience alone-time within daily life. As a result, the solitude offered by wilderness landscapes has become all the more valuable. Past research on wilderness solitude has been divided into two distinct frameworks: the Social-Spatial Perspective and the Humanistic Perspective. This distinction has severely limited the development of a comprehensive research model that incorporates all the possible conditions relating to wilderness solitude. This study synthesized past research and theory to create a quantitative model of wilderness solitude which includes elements from both research perspectives, while …

40 Years On The International Flathead: An Assessment Of Transboundary River Governance, Jedd Sankar-Gorton

Graduate Student Theses, Dissertations, & Professional Papers

Global population growth, climate change, and industrialization, are putting extreme pressures on worldwide freshwater supplies (Cosens 2010). Of the global freshwater supplies, transboundary water sources play a crucial role in sustaining populations. Over 40% of humans on Earth rely on a transboundary river or lake for access to water, and 90% of the world’s population lives in countries that share bodies of water with at least one other country (UN 2008). Taken together, the motivations for improving governance of transboundary water systems have never been stronger. To meet the challenges associated with transboundary water governance, researchers working at multiple scales …

Volunteering For Vegetables: Community Agriculture And The Prospects For Building A More Democratic Food System, Kali Orton

Graduate Student Theses, Dissertations, & Professional Papers

Scholars and activists hold varied ideas about what a more just and equitable food system might look like. Food democracy, one of these alternative food system theories, centers around the idea that all people should have equal opportunity to meaningfully contribute to the shaping of their food systems. Community farms, due to their socially-oriented qualities, present one possibility for people to develop the skills and knowledge necessary to function as food citizens and build food democracy.

This research explores and seeks to inform food democracy theory through case studies of two urban community farms – one in Missoula, Montana, and …

Greening Of The Arctic: Plot-Scale Analysis Of Interactions Between Climate, Vegetation, And Permafrost At Toolik Lake, Alaska (1995 - 2017), Brianna Rick

Graduate Student Theses, Dissertations, & Professional Papers

Air temperatures across the Arctic have increased in recent decades, and through complex feedbacks, vegetation and permafrost (frozen ground) are actively responding as climate warming continues. This study investigates the trends and interactions of observed air, soil-surface temperature (SST), and active-layer thickness (ALT) at Toolik Lake on the Alaskan North Slope between 1995 and 2017, as well as vegetation change over time.

Time series between 1995 and 2017 at CALM site U12B, a 1 ha plot near Toolik Lake, reveal an increase (0.50 °C/decade) in mean summer (Jun-Aug) air temperatures and a decrease (­0.23 °C/decade) in mean summer SST. In …

Why Does Drought Kill Trees? Interactions Between Water, Carbon, And Fungal Symbionts, Gerard Sapes De Moreta

Graduate Student Theses, Dissertations, & Professional Papers

One of the global causes of forest die-off is climate-change induced drought. Drought kills trees by reducing water supply and non-structural carbohydrate (NSC) availability and by increasing susceptibility to negative biotic interactions. However, we lack an understanding of how water, NSC, and biotic agents interact. As a result, we still cannot accurately predict drought-induced mortality. The overarching goal of my dissertation is to increase our understanding of the interacting mechanisms leading to drought-induced mortality (DIM) and to identify physiological variables that accurately predict risk of DIM. Via greenhouse experiments with Pinus ponderosa (ponderosa pine) seedlings, I addressed three overarching research …

Life On The Edge: Risk Of Predation Drives Selection Of Habitat And Survival Of Neonates In Endangered Sierra Nevada Bighorn Sheep, Shannon Forshee

Graduate Student Theses, Dissertations, & Professional Papers

Long-term viability of endangered populations requires development of effective management strategies that target the population vital rate with the highest potential to influence population trajectories. When adult survival is high and stable, juvenile recruitment is the vital rate with the greatest potential to improve population trajectories. For my thesis I examined how lactating Sierra Nevada Bighorn sheep (Ovis Canadensis sierra) balance forage and predation risk during the neonatal period. I first identified resource selection strategies employed by lactating females to promote survival of neonates and then determined the primary factors affecting survival of neonates. I found lactating females selected for …

Technical Feasibility And Life Cycle Cost Assessment Of A Photovoltaic Array On Trinity Dam, Trinity County, Ca, Caleb Aaron Patrick

Cal Poly Humboldt theses and projects

Public lands owned by the Bureau of Land Management are increasingly being used for photovoltaic (PV) system development. Although numerous policies support PV deployment on public lands, those managed by the Bureau of Reclamation have not been considered for PV development. Hydro-electric embankment dams, both publicly and privately owned, may have the potential to be development sites for distributed PV systems. A technical feasibility report was conducted for a case study of a PV installation on Trinity Dam, Trinity County, CA, and found embankment dams could potentially be feasible development sites. A mounting analysis found that a concrete slab reinforced …

Chicana Feminist Participatory Action Research: Collaborative Environmental Justice In The Imperial Valley And The Identifying Violations Affecting Neighborhoods Community Development Project, Kristian Michelle Salgado

Cal Poly Humboldt theses and projects

In 2007 in Imperial County, a community-based organization called Comite Civico del Valle (CCV), along with the Department of Toxic Substances, and concerned residents, created the Identifying Violations Affecting Neighborhoods (IVAN). IVAN is a community-based environmental reporting and monitoring system that is built on the idea that residents are the most knowledgeable about their environment and therefore should have a place at the table alongside environmental regulation agencies. For more than a decade, this has allowed residents to better report environmental concerns. However, for many residents there is still a lack of knowledge about how to properly utilize the IVAN …

Dead Clams Tell Tales: A Seasonal Analysis Of Jeaga Shell Mounds In Jupiter Inlet 1, Kia Riccio

Harriet L Wilkes Honors College Theses 2010 - 2019

This archaeological research aims to expand our modern understanding of Florida pre-history by studying the faunal remains in a Jeaga village. I examine shell deposits from Dubois Park (Jupiter, FL) during Jeaga occupation. The Jeaga were a non-agricultural coastal people who occupied what is now Palm Beach County. DuBois Park maintains one of the largest and best preserved Jeaga shell mounds in the state. The mound was primarily composed of Mollusk shell and associated midden deposits containing shell, faunal remains, and earthenware. Using sclerochronolic growth band data, I determined Jeaga harvesting patterns of hard-shell clams. My research suggests that the …

How Behavior Of Nontarget Species Affects Perceived Accuracy Of Scat Detection Dog Surveys, Karen E. Dematteo, Linsey W. Blake, Julie K. Young, Barbara Davenport

United States Department of Agriculture Wildlife Services: Staff Publications

Detection dogs, specially trained domestic dogs (Canis familiaris), have become a valuable, noninvasive, conservation tool because they remove the dependence of attracting species to a particular location. Further, detection dogs locate samples independent of appearance, composition, or visibility allowing researchers to collect large sets of unbiased samples that can be used in complex ecological queries. One question not fully addressed is why samples from nontarget species are inadvertently collected during detection dog surveys. While a common explanation has been incomplete handler or dog training, our study aimed to explore alternative explanations. Our trials demonstrate that a scat’s genetic …

American Black Bear Den-Site Selection And Characteristics In An Urban Environment, Toryn L. J. Schafer, Stewart W. Breck, Sharon Baruch-Mordo, David L. Lewis, Kenneth R. Wilson, Julie S. Mao, Thomas L. Day

United States Department of Agriculture Wildlife Services: Staff Publications

Selection of den sites is a crucial aspect of American black bear (Ursus americanus) life history. High-quality dens provide thermal insulation, protection from disturbance, suitable environment for parturition and cub development, and proximity to available forage upon emergence. Black bears are increasingly coexisting with people in human-dominated landscapes; however, little is known about whether urban environments influence characteristics of dens and den site selection. Our objective was to determine the effect of housing density (a proxy for human activity and availability of anthropogenic resources) on selection of den sites in years of good and poor natural forage.We additionally …

Using Contingent Valuation To Measure The Economic Impact Of Climate Change On Hiker Recreation During New England Peak Foliage, Marina J. Bowie

Honors Theses and Capstones

This paper seeks to define and develop an economic tool for measuring willingness to pay for hiking recreation in the face of climate change in New England during the peak foliage season. Potential climate change impacts to New England are defined, along with relevant economic tools for measuring the market value of non-marketed goods. Ultimately, contingent valuation is chosen as the most viable option, and a survey is developed, pretested, and ready for implementation at the trailhead of Mt. Major in New Hampshire.

Trace Element Concentrations In The Small Indian Mongoose (Herpestes Auropunctatus) From Hawaii, Usa, Sawako Horai, Yusuke Nakashima, Kanae Nawada, Izumi Watanabe, Tatsuya Kunisue, Shintaro Abe, Fumio Yamada, Robert Sugihara

United States Department of Agriculture Wildlife Services: Staff Publications

Concentrations of 26 trace elements including essential (Mg, Ca, Cr, V, Mn, Fe, Co, Ni, Cu, Zn, Se, Sr and Mo) and toxic (As, Cd and Pb), were determined in the liver, kidney, brain, hair, muscle, and stomach contents of the small Indian mongooses inhabiting eight areas on three Hawaiian Islands, Oahu, Maui and Hawaii. There were significant differences in concentrations of some metals among the habitats. Cadmium concentrations in mongooses from the macadamia nut orchards on Island of Hawaii were relatively higher than those in populations from other seven areas. Lead concentrations in mongooses from the Ukumehame firing range …

Diet And Nesting Habitat Of Wading Birds In A Shallow, Eutrophic Lake, Jenna C. May

Electronic Theses and Dissertations 2010 - 2019

Avian reproductive success varies depending on environmental conditions, degree of predation, location, and food availability. I examined food availability and nesting habitat of wading birds in South Florida. Evaluating prey availability and prey used by two small heron species demonstrated the ability for small herons to maintain consistent diets through fluctuating environmental conditions, within and across different wetland types. Small herons may be able to cope with environmental changes by altering foraging locations and strategies. Regarding nesting habitat, man-made sites may provide habitat comparable to natural sites, at least in the short-term. The nest’s position can influence its susceptibility to …

Searching The Internet To Estimate Deer Population Trends In The U.S., California, And Connecticut, G. Webb

Faculty Research, Scholarly, and Creative Activity

Information for decision making may be publicly available, but costly to obtain. As an experiment in environmental scanning, the internet was searched on a daily basis over several years to collect information and provide analysis related to decisions on deer management. The process discovered that, contrary to common assumptions, the U.S. deer population has apparently been falling since about the year 2000 based on analysis of available state data that had not been aggregated. In some cases, state population estimates were created using standard procedures on available data. Results indicate that differences in survey methods appear to be relatively constant …

Emotions Predict Policy Support: Why It Matters How People Feel About Climate Change, Susie Wang, Zoe Leviston

Research outputs 2014 to 2021

Current research shows that emotions can motivate climate engagement and action, but precisely how has received scant attention. We propose that strong emotional responses to climate change result from perceiving one's “objects of care” as threatened by climate change, which motivates caring about climate change itself, and in turn predicts behaviour. In two studies, we find that climate scientists (N = 44) experience greater emotional intensity about climate change than do students (N = 94) and the general population (N = 205), and that patterns of emotional responses explain differences in support for climate change policy. Scientists tied their emotional …

Predicted And Measured Acute Toxicity And Developmental Abnormalities In Zebrafish Embryos Produced By Exposure To Individual Aromatic Acids, Steven J. Rowland, Alan G. Scarlett, Yuktee Dogra, Darren Rowe, Tamara S. Galloway

More Faculty of Science and Engineering Research

Petroleum acids, often called 'Naphthenic Acids' (NA), enter the environment in complex mixtures from numerous sources. These include from Produced and Process-Affected waters discharged from some oil industry activities, and from the environmental weathering of spilled crude oil hydrocarbons. Here, we test the hypothesis that individual NA within the complex mixtures can induce developmental abnormalities in fish, by screening a range of individual acids, with known chemical structures. Sixteen aromatic NA were tested using a Thamnocephalus platyrus (beavertail fairyshrimp) assay, to establish acute toxicity. Toxicities ranged from 568 to 8 μM, with the methylbiphenyl acid, 4-(p-tolyl)benzoic acid, most toxic. Next, …

President Trump Tweets Supreme Leader Kim Jong-Un On Nuclear Weapons: A Comparison With Climate Change, David E. Allen, Michael Mcaleer

Research outputs 2014 to 2021

A set of 125 tweets about North Korea's Supreme Leader Kim Jong-Un by President Trump from 2013 to 2018 are analysed by means of the data mining technique, sentiment analysis. The intention is to explore the contents and sentiments of the messages contained, the degree to which they differ, and their implications about President Trump's understanding and approach to international diplomacy. The results suggest a predominantly positive emotion in relation to tweets about North Korea, despite the use of questionable nicknames such as "Little Rocket Man". A comparison is made between the tweets on North Korea and climate change, madefrom …
