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 …

Trends In Nectar Concentration And Hummingbird Visitation: Investigating Different Variables In Three Flowers Of The Ecuadorian Cloud Forest: Guzmania Jaramilloi, Gasteranthus Quitensis, And Besleria Solanoides, Sophie Wolbert

Independent Study Project (ISP) Collection

Many variables affect hummingbird visitation to flowers, including nectar concentration, time of day, corolla length and other aspects of flower morphology, and elevation. Nectar concentration was measured from flowers of three Ecuadorian subtropical montane species: Guzmania jaramilloi, Gasteranthus quitensis, and Besleria solanoides. Concentration values were compared across varying times of day, corolla lengths, and elevations to determine the effects of these variables on flower nectar concentration. Camera traps were also used to observe hummingbird visitation to the above three flower species. After running regression and ANOVA analyses, nectar concentration was found to be positively correlated with time …

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 …

Harpy Eagle (Harpia Harpyja) Conservation: Juvenile Behavior And Diet At A Nest Near Pijibasal, Darien, Hannah Rodgers

Independent Study Project (ISP) Collection

The Harpy Eagle (Harpia harpyja), the largest and most powerful bird of prey in the Americas, is declining throughout its range in Neotropical forests. Hunting and deforestation threaten populations in the most important remaining eagle habitat in Central America, the Darien province of Panama. These eagles may have the longest postfledging juvenile dependency of any raptor, though juvenile behavior during this period is poorly studied. This study monitored an 11-month-old juvenile for 7 days at a nest near the indigenous community of Pijibasal in order to study behavior and diet. Researchers recorded the juvenile’s location and behavior, studied prey remains …

Continuing Efforts To Alleviate "Orange Pain" An Internship With The Da Nang Association Of Victims Of Agent Orange/Dioxin, Loan Heilner

Independent Study Project (ISP) Collection

This year marked the 55th anniversary of Vietnam’s Agent Orange Disaster. Decades after the end of the war, Vietnamese people are still largely being affected by the remnants of the United States’ Agent Orange herbicide sprays. Dioxin chemical has now been confirmed detrimental to human and environmental well-being, but unfortunately it still remains in high concentrations in certain areas of Vietnam. Dioxin chemical is passed on through genetics to new generations, but one of the leading causes of dioxin-related health defects today are due to environmental residue. In Da Nang, Agent Orange was stored and loaded at the local airbase …

The world’s oceans are becoming increasing acidic due to global climate change, posing a threat to marine ecosystems, including coral carbonate systems. Environmental threats are exacerbated by human development stressors as well: growing populations, dependency on marine resources, and unsustainable practices invaluable marine ecosystems at risk. Tanzania’s coral reef system extends for 3580 km2 (Muhando et al. 2008) near the Tanga region, serving over half a million people who are highly dependent on fishing and other marine resources as their livelihoods (Samoilys et. al. 2008). With Tanzania’s population rapidly growing, the unsustainable pressure on coral reefs for sustenance and livelihood …

Proxy Dating In Iceland Testing The Validity Of Silene Acaulis As A Phytometric Proxy, Madelyn Grant

Independent Study Project (ISP) Collection

Climate change is causing drastic changes in the cryosphere, particularly in the Arctic region where average warming is 1.9 times greater than in the rest of the world due to Arctic amplification. Understanding the response of essential climate variables such as glaciers and ice caps to rapid Arctic warming is essential to predicting future changes in the Arctic region and around the world. Proxy dating methods can help construct a record of warming-induced glacial retreat in areas where long-term monitoring systems are not in place. In Arctic regions, the cushion plant Silene acaulis represents one of the only feasible proxies …

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 …

Water Resource Change And Management: Implications Of Climate Change And Water Resource Management For Pastoral Herders In Bayan Ulgii, Rachel Ryan

Independent Study Project (ISP) Collection

Mongolia is the 8th most vulnerable country in the world to climate change. The water regime of Mongolia is therefore experiencing intensive change with significant effects in the availability, distribution, and security of water resources. The implications of this change are exacerbated when aligned with poor water resource management, an issue that is prevalent as water regime change challenges current water management systems. These implications specifically affect the vulnerable rural population of Mongolian herders who maintain the practice of nomadic pastoralism. In the western province of Bayan Ulgii, the change in the numerous glaciers and other water resources that are …

Secretarial Order 3336 Science Priorities: The Role Of Science Past, Present, And Future, Stephen W. Barrett

Joint Fire Science Program Digests

Within sagebrush (Artemisia spp.) ecosystems, which are home to more than 350 species of plants and animals, potentially more frequent and severe fires are causing an increased threat to human safety, property, rural economies, and wildlife habitat. In particular, the habitat of the greater sage-grouse (Centrocercus urophasianus), an iconic sagebrush-dependent species, is at risk. In response to this reality, on January 15, 2015, Secretary Sally Jewell signed Secretarial Order 3336 (S.O. 3336), titled “Rangeland Fire Prevention, Management, and Restoration.” The main purpose of the order is to implement enhanced policies and strategies for managing rangeland fire and …

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 …

The Importance Of Nature: An Investigation On How Geography Influences Well-Being, Christina Cobb

Independent Study Project (ISP) Collection

The objective of this community service project (CSP) was to study how a community’s location, specifically within nature, influences their well-being. I hoped to see how the community’s location, within Chapada Diamantina national park, influences the many ways health is promoted, and how these ways are affected by their location within nature. This project was built upon a review of the literature, which found that there is a theoretical basis for the notion that contact with nature is beneficial, a term deemed Biophilia. There is a robust body of academic research that highlights the health benefits deriving from contact …

Enso Controls Interannual Fire Activity In Southeast Australia, Michela Mariani, Michael-Shawn Fletcher, Andrés Holz, Petter Nyman

Geography Faculty Publications and Presentations

El Niño–Southern Oscillation (ENSO) is the main mode controlling the variability in the ocean-atmosphere system in the South Pacific. While the ENSO influence on rainfall regimes in the South Pacific is well documented, its role in driving spatiotemporal trends in fire activity in this region has not been rigorously investigated. This is particularly the case for the highly flammable and densely populated southeast Australian sector, where ENSO is a major control over climatic variability. Here we conduct the first region-wide analysis of how ENSO controls fire activity in southeast Australia. We identify a significant relationship between ENSO and both fire …

The Effects Of Sub-Lethal Predation On The Reproductive Output Of Acanthaster Planci (Crown-Of-Thorns Starfish), Emily Mucha

Independent Study Project (ISP) Collection

Wide-scale declines in live coral cover have been observed throughout history. Modern day coral populations face a multitude of environmental disturbances, however one of the most devastating to the reefs in the Indo-Pacific is the crown-of-thorns starfish (Acanthaster planci), which feeds on the tissues of live corals. The rate at which these individuals feed combined with the explosion of populations in times of outbreak have been seen to exert some of the biggest pressures on coral reefs to date. Following recent episodes of crown-of-thorns starfish (COTS) outbreaks, research on the organism has become increasingly prevalent on the scientific …

While fecal hormone analyses are routinely employed to monitor reproduction in mammals, few studies have used these techniques for monitoring reproductive events in birds. This study describes the endocrine patterns associated with reproduction in the blue-throated piping guan (Pipile cumanensis), a less threatened relative of the critically endangered Trinidad piping guan (P. pipile). Fecal samples were collected approximately once a week for 3 years from seven female guans and six male guans at the Saint Louis Zoo. Concentrations of fecal progestagens, estrogens, and androgens were quantified using commercially available enzyme immunoassays. Baseline progestagen concentrations for females …

Critical Youth Participatory Action Research To Reimagine Environmental Education With Youth In Urban Environments, Marissa E. Bellino

Dissertations, Theses, and Capstone Projects

This work addresses ways to actively engage youth, particularly those growing up in urban contexts, in the rapidly expanding field of urban environmental education (EE). By inviting youth into the urban EE discourse, this study created opportunities to redefine what EE could look like when it is built on relevance to youth daily lives and is locally situated in urban settings. A critical urban environmental pedagogy, as conceptualized in this dissertation, brings together critical pedagogy and youth participatory action research to investigate the diversity of urban neighborhoods by youth who live there. These investigations reveal neoliberal urbanization processes and their …

Differentiating Urban Forms: A Neighborhood Typology For Understanding Urban Water Systems, Douglas B. Jackson-Smith, Philip A. Stoker, Martin Buchert, Joanna Endter-Wada, Carlos V. Licon, Molly S. Cannon, Shujuan Li, Zack Bjerregaard, Luke Bell

Environment and Society Faculty Publications

With rising populations and changing climates, urban areas need water systems capable of meeting a range of social, economic and environmental sustainability objectives. Different configurations of urban growth and development also produce varying water system outcomes. In this paper we develop a multi-dimensional classification scheme that identifies distinct configurations of ‘urban forms’ in Northern Utah, USA. We identified characteristics within urban landscapes that have been linked in the scientific literature to three types of water outcomes: water demand, water budgets, and water quality. Using publicly-available data at the census block scale, we create a typology of urban neighborhoods that share …

Urban Agriculture As Embedded In The Social And Solidarity Economy Basel: Developing Sustainable Communities, Isidor Wallimann

Program for the Advancement of Research on Conflict and Collaboration

The Social and Solidarity Economy (SSE) is a viable strategy in dealing with some contemporary problems known both in industrial and developing countries. Addressed is how local populations could reach certain objectives and satisfy certain needs using techniques characteristic of SSE and, thus, carve out a social and economic space of their own vis-à-vis anonymous markets, global actors, local and national elites. Illustrated further is this strategy on the example of Urban Agriculture Basel, a unit of the Social Economy Basel. Within this self governed space, it is suggested, a path can be laid for the necessary transition towards local, …

Failure To Communicate: Inefficiencies In Voluntary Incentive Programs For Private Forest Owners In Michigan, Mark. D. Rouleau, Jennifer F. Lind-Riehl, Miranda N. Smith, Audrey L. Mayer

College of Forest Resources and Environmental Science Publications

Coordinating forest management across thousands of nonindustrial private forest (NIPF) owners is a difficult yet necessary task for state land management agencies. Voluntary Incentive Programs (VIPs) can coordinate the decentralized activities of these owners in return for services or financial incentives. However, many VIPs typically have low enrollment. Our study investigates the implementation of VIPs to increase forest management coordination among NIPFs in Michigan. We present findings from 20 semi-structured interviews with leaders of state and local land management organizations, and government officials at state natural resource agencies, and contrast their answers with those recorded from 37 interviews of NIPF …

Conflict Of Interest In Exploitation And Utilisation Of Transboundary Natural Resources On Lake Victoria, Edmond M. Were

Journal of African Conflicts and Peace Studies

The management of Lake Victoria as a “regional common” is expected to adhere to the global principles of transboundary natural resource management. However, national interest and power asymmetry amongst riparian states buoyed by external demand have overwhelmed global and regional norms leading to incessant exploitation of the common resources. This paper uses idealist and realist perspectives of power relations to inform the analysis of conflicting interests in transboundary natural resource exploitation. It partly relies on 2012-2013 primary data from purposively selected Beach Management Units in Kenya and Uganda and secondary data from regional fisheries institutions. Notwithstanding the normative value of …

Application Of Life Cycle Assessment Method For Environmental Impact Assessment Of Fired Brick Production Plant In Thailand, Rutjaya P. Na Talang, Sanya Sirivithayapakorn

Applied Environmental Research

In many Asian countries, fired bricksare producedby burning raw bricks in a rudimen-tary clamp kiln without pollution control mechanisms, a practice which contributes to several kinds of environmental impact. This research investigated the inputs and outputs associated with production of fired bricks using the rice husk-fuelled clamp kiln. Data collected includedraw material use, energy, products, emissions and kiln temperatures. To quantify environmental impacts, the consequential-focused life cycle assessment (LCA) approach was adopted. The impactswere assessed in terms of fuel substitution as the acquisition of another fuelwas re-quired to substitute for electricity. The findings indicated that the clamp kiln technology pro-duced …
