Visualizing Ozone Pollution In The Denver Metro Area Using A Bioindicator Garden, Ella K. Mathews, Hillary Hamann, Julie Morris, Erica L. Larson

DU Undergraduate Research Journal Archive

Since the industrial revolution, widespread fossil fuel combustion has significantly increased atmospheric pollution. The combustion of fossil fuels releases nitrogen oxides (NOx) and volatile organic compounds (VOCs), which form tropospheric (ground-level) ozone when exposed to sunlight. Ozone directly harms plants by disrupting their ability to absorb carbon dioxide, release oxygen, and carry out photosynthesis. Bioindicator species are plants that have visible responses to environmental conditions, such as ozone, and can act as “canaries in the coal mine,” indicating the health of their environment. In this study, we used a garden of ozone bioindicator species (ozone garden) as a cost-effective tool …

King Of The Jungle: Comparative Analysis Of The Geopolitical Narratives Surrounding Fordlandia And A Proposed Resort Park In El Mirador, Rachel Jaeger

DU Undergraduate Research Journal Archive

Environmental geopolitics is a field of study in which narratives about the environment are analyzed to reveal the underlying motivations and objectives they support. Using Shannon O’Lear’s (2020) framework of environmental geopolitics, I conduct a comparative analysis of the narratives surrounding two distinct development projects: Henry Ford’s historical company town in the Brazilian Amazon, Fordlandia, and a proposed ecotourism resort park in El Mirador, Guatemala. Analysis of Fordlandia reveals a narrative of American frontierism and a man-versus-nature perspective that served to paint the environment as belligerent and thereby justify corporate control and Indigenous assimilation. Narratives surrounding El Mirador differ, representing …

Greenspace Access In The Denver Metro Region: Historical Housing Policy Impact On Modern Greenspace Distribution, Brody Petig, Susan Dagget

DU Undergraduate Research Journal Archive

Access to safe, high quality, urban green spaces is widely recognized as a determinant for physical health, mental well-being, and social cohesion. Existing literature has demonstrated that race, age, gender, and socioeconomic status frequently dictate the allocation of resources and shape disparities in access to greenspace. These disparities are also often reflective of historical housing policy and zoning decisions. This paper examines greenspace access in the Denver Metro Region (DMR) and the City and County of Denver (CCD) through a social justice lens, with particular attention to the relationship between historical housing policy and contemporary trends in greenspace distribution and …

Integrating Local Ethnobiology Into Sustainable Forest City Development In Indonesia's New Capital City, Tri Atmoko, Mukhlisi Mukhlisi, Bina Swasta Sitepu, Ulfah Karmila Sari, Eko Herwanto, Deny Adi Putra, Tri Rizkiana Yusnikusuma

Forest and Society

The Nusantara new capital city has been a national strategic program based on Indonesian's sustainable forest city concept. In the future, there will be a migration of 1.9 million people from different islands, indigenous, and religions, carrying their own cultures. It will suppress the existence of local cultures. Local culture lives in harmony with nature, but massive development will impact the presence of forests and their culture. This research aims to document various local cultures related to ethnobiology (plants and wildlife) of the indigenous in the Nusantara region and its surroundings (Dayak, Paser, and Kutai). The research was conducted through …

The Role Of Anticipatory, Preparatory, And Transformative Governance In Wildfire And Watershed Resilience Strategies, Robin Kundis Craig, Melinda Morgan

Natural Resources Journal

Wildfire is a game-changer for both communities and ecosystems throughout the West, including in New Mexico. Building resilience to increasing numbers of wildfire events, especially when wildfires can shift communities, ecosystems, and combined social ecological systems (“SESs”) past tipping points and into new regimes requires new approaches to governance. Focusing on the Hermit’s Peak/Calf Canyon fire and New Mexico residents’ ongoing response, this Article examines post-fire needs before surveying new modes of governance that can help to address those needs in a climate change era. It ends with a summary of our engagement with the participants in the “Life After …

Effects Of Warming On Growth And Leaf Colonization By Litter Mat-Forming Fungi In A Wet Tropical Forest In Puerto Rico, Ari E. Puentes, D. Jean Lodge, Deyaneira A. Ortiz-Iglesias, Tatiana Barreto-Vélez, Laura C. Rubio-Lebrón, Hieu Chu, Christine S. O'Connell, Sasha C. Reed, Tana E. Wood

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Wet tropical forests are experiencing rising temperatures and increased frequency and intensity of extreme climatic events, such as cyclones, which can increase rates of soil erosion and surface runoff. Fungal litter mats, formed by agaric decomposer fungi, play a crucial role in stabilizing slopes, preventing erosion, and aiding nutrient cycling; however, little is known about how warming affects litter mat growth and function. We investigated two litter mat-forming fungi, Gymnopus johnstonii and Marasmius aff. crinis-equi, in warmed (+4°C above ambient) and control plots in the Luquillo Experimental Forest, Puerto Rico. Growth and time-to-leaf colonization were monitored over 6 weeks …

Improving Human-Wildlife Coexistence: An Ecological And Educational Approach To Rewilding Grizzly Bears (Ursus Arctos Horribilis) In California, Amanda C. D. Rosales

Master's Projects and Capstones

Megafauna extinction during the Holocene has been both caused and amplified by climatic changes and human influence. By the last half century, large carnivores were diminished in Europe and the United States, but policies increasingly addressed species decline and their territories expanded. This research examined large carnivore rewilding across the European Union and United States, specifically for rewilding brown bears, Ursus arctos, in historic habitat. Next, case studies for the health status of climate-impacted whitebark pine, Pinus albicaulis, a high energy food for bears, was assessed. Ultimately, research case studies, human perspective surveys, and the California Department of Education content …

Master's Projects and Capstones

Pharmaceutical compounds are increasingly detected in urban water systems worldwide, posing significant ecological and public health risks in cities where wastewater treatment infrastructure is insufficient to remove them. This study evaluates the presence of pharmaceutical compounds in Bogotá's wastewater systems, the effectiveness of current treatment technologies for their removal, and the regulatory and monitoring gaps that hinder their management as emerging contaminants of concern. A systematic literature review was conducted to assess the occurrence of pharmaceuticals in municipal and hospital wastewater, as well as in effluents from wastewater treatment plants (WWTPs) and receiving surface waters in Colombia, with particular focus …

Crop Yield Shocks And Conflict In Sub-Saharan Africa: Subnational Evidence From Satellite-Based Yield Predictions, Benson I. Adomako

Master's Theses

This paper examines whether crop yields affect violent conflict at the subnational level across seven Sub-Saharan African countries: Burkina Faso, Ethiopia, Mali, Malawi, Niger, Nigeria, and Tanzania, over the period 2010 to 2024. A central identification challenge is that observed yields are endogenous to conflict: armed violence disrupts planting, cultivation, and harvest. To address this, I train a machine learning model on observed maize yield and satellite and environmental features to generate predicted yields for 1,338 second-level administrative districts annually. These predictions serve as the key regressor in a two-way fixed-effects panel with district and year fixed effects. I find …

O'Connell

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Methane (CH₄) is a potent greenhouse gas, and tropical forests account for roughly one–third of global atmospheric CH₄ uptake by soils. Projected warming and more frequent hurricanes in these ecosystems may alter soil CH₄ sink strength, as warmer and wetter soils enhance methanogenesis activity. We measured soil CH₄ and CO₂ efflux during the calendar summer months of 2023 and 2024 alongside continuous records of soil moisture, soil and air temperature, and precipitation in an in–situ warming experiment (TRACE) located in a lowland tropical forest in Puerto Rico, six to seven years after Hurricanes Irma …

Irish Journal of Tourism, Hospitality, Leisure and Event Research

While sustainable tourism practices have long been acknowledged for their potential to reduce negative impacts and enhance positive outcomes, their effectiveness is often hindered by several challenges. These include a considerable gap in skills and inadequate collaboration between practitioners and educators. To meet these pressing challenges, it is essential to strengthen awareness, enhance collaboration between industry and educators, and develop the critical skills needed to champion responsible and sustainable tourism in European regions. As the principles of sustainability advocate for equitable management of tourism destinations combined with the upward growth in tourism activity in Europe post pandemic, there is an …

Kev's Dinghy Boat Workshops, Ruiyang Xiao

Masters Theses

In a culture where convenience replaces process, this project argues that making — even when inefficient, imperfect, or unnecessary — enables forms of engagement that buying cannot.

Technologies and Services nowadays are able to fulfill human’s desire to travel and explore at ease. However, this convenience proposes a mode of engagement based only in deeper knowledge of context and thus our experience with the world around us is hence diminished. Our engagement with the world becomes heavily mediated, regulated and controlled.

This project investigates how hands-on engagement with water can reintroduce + restore our sense of joy, curiosity, consequence, and …

Care Ecologies Between Knots, Eliza R. Marris

Masters Theses

Discarded fibers like raw wool behave the way harm reduction does. Harm reduction resists stigma and works to move beyond assumptions and oversimplifications of substance use and addiction. Wool is irregular, complicated, and emotionally charged. It resists compression and maintains its own being even when pulled apart. Working with raw wool is in relationship with complexity, as is harm reduction.

At its core, harm reduction is grounded in thoughtfulness and empathy towards people, their lived experience, and its nuances. It is a witness to lives, memories, and imprints, acknowledging the entangled realities of addiction. Our detachment from fiber remainders, materials …

Weaving Grounds: Connecting Canyons And Empowering Borderland Communities, Maria D. Lopez Vazquez

Masters Theses

National policies materialize in the United States-Mexico political divide, also known as the borderlands. Willow Canyon is a dissected land form inextricably linked to the Tijuana River watershed, forming with the adjacent landforms on both sides of the border one landscape. The Guadalupe Hidalgo Treaty¹, signed in 1848 by the US and Mexican governments, traced an arbitrary line across these landscapes, disregarding their relationship. The consequences of these actions are visible in the physical deterioration of the landscape and ecology, as the hydrological cycle has been modified. In the 1940’s, the picturesque flow of Willow Canyon was dissected by urbanization, …

American Paradise, Virginia Hanusik

Masters Theses

The following is a collection of stories and ideas about the making of our physical and emotional worlds, along with their fracturing, deconstruction, and degradation within the American industrial landscape.  It suggests the value of the unknown and the grace of mistakes, emotional and material friction, and the hiccups that come with learning.

For American Paradise, I’m bringing my interest in landscape extraction, and the people and families within them, to my own autobiography. In this work I turn to where I grew up, the people that brought me there, my connection to manual labor, and the use of specific …

Hidden Systems, Samuel Choi

Masters Theses

Across buildings and cities, moisture is managed, concealed, and discharged through convoluted systems of containment. Still, water ultimately resists this framework. It reveals itself as leaks, puddles, condensation—moments typically understood as technical failure. Hidden Systems reframes these conditions as architectural knowledge, one that becomes evidence of water’s material capacity, limits of infrastructure, and a record of time.

NYC is constructed on, powered by, and profiting from water. Although it hosts a robust network, seepages disrupt control, allowing systems to be traced across scales. As pipes expand, contract, and freeze, the project unfolds seasonally, moving through water’s three states: solid, liquid, …

Environmental Mercury Alters Immune Pathways Linked To Autoimmune Risk In Mice Mirroring Humans, Maurgan Lee, Paul Stemmer, Randall Gill, Allen Rosenspire, Anil Aranha, Heather Gibson

Medical Student Research Symposium

Background and Purpose: Mercury is a pervasive environmental contaminant, and human epidemiologic studies have linked chronic low-level exposure to increased autoimmune disease-risk. Dysregulated lymphocyte activation and impaired signaling tolerance are central mechanisms in human autoimmunity. Protein phosphorylation governs lymphocyte differentiation and function, alterations in phosphoproteomic networks may represent a signature of immune disruption. This study evaluates how low dose mercury exposure modifies B and T cell abundance and intracellular signaling patterns in BALB/c and Diversity Outbred (DO) mice.

Methods: BALB/c and DO mice were exposed to low dose HgCl2 in their water for two weeks or provided standard water controls. …

Towards The Integration Of Living Plants In Urban Design For Desert Regions \Fontsize1213\Selectfont\Textcolorblack(A Dynamic Shading Unit Inspired By Plant Movements), Amira Medhat Ibrahim Gouda

HBRC Journal

With the rapid urban expansion of new cities in hot desert climates, the challenge of designing open urban spaces and public squares becomes evident, particularly in providing thermal comfort. These spaces are exposed to intense sunlight and temperatures exceeding 40°C for extended periods, limiting their usability and increasing reliance on traditional, non sustainable shading methods. Addressing this issue, the research explores the potential of bio-dynamic shading units that utilize plants with self-moving responses such as nyctinastic and heliotropic movements as sustainable alternatives that adapt automatically to climatic changes without mechanical systems or energy consumption. The study assumes that integrating plants …

Goodness-Of-Fit Test For The Kumaraswamy Distribution Via Energy Distance Approach With Applications To Real Data, Joseph Njuki, Thomas Gilbert

Mathematics and Statistics

In this article, we develop a goodness-of-fit test for the Kumaraswamy distribution based on energy statistics. Due to the availability of its quantile (inverse) function, the Kumaraswamy distribution has been shown to be the preferred alternative to the Beta distribution, since both have bounded support in the (0,1) interval. The proposed test procedure is simple and more powerful against general alternatives. Under different settings, simulations show that the proposed test is capable of being well controlled for any given significance (nominal) levels. In terms of power comparisons, the proposed test outperforms other existing methods in different settings. We then apply …

Modeling Alternative Futures: Scenario-Based Land-Use And Land-Cover Projections For Nepal (2030-2050), Gita Bhushal, Pankaj Lal

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Nepal has undergone significant land-use and land-cover (LULC) changes from 2000 to 2020, driven by urbanization, agricultural shifts, and broader socioeconomic dynamics. This study analyzes historical changes and projects LULC dynamics for 2030, 2040, and 2050 across four scenarios: Business-as-Usual (BAU), Rapid Urban Development (RUD), Forest Degradation and Terai Contraction (FDTC), and Agricultural Land Abandonment and Ecological Recovery (ALER). A CA-Markov modeling framework in TerrSet was used to simulate future land-use patterns, utilizing scenario-specific transition probability matrices and spatial constraints to reflect different socio-economic and policy assumptions. Under the BAU scenario, land-use change remains moderate, characterized by gradual urban expansion …
