Advances In Amino Acid Analysis For Marine Related Matrices And Its Application To Coastal Shelf Settings In The Canadian Arctic, Rachel M. Mcmahon

OES Theses and Dissertations

Amino acids comprise up to 50% of organic matter in cellular material and are a major fraction of oceanic organic carbon. Amino acids are also considered highly labile during organic matter recycling, making them useful proxies for organic carbon cycling. Nevertheless, analysis of individual amino acids has been burdened by lengthy derivatization and complex analysis since the 1950s. In this thesis, I describe the modification of advanced analytical techniques, developed in the biomedical field, for analysis of marine matrices which allow the determination of at least 40 amino acids without the need for lengthy sample preparation and derivatization, twice the …

Creating A Culture For Outdoor Environmental Education In An Elementary Setting, Daniel Huldeen

School of Education and Leadership Student Capstone Projects

Many elementary educators believe in the importance of providing opportunities for outdoor environmental education but fewer actually offer activities and lessons to their students. A review of the literature detailed the many benefits that outdoor environmental education offers to students. It was also clear through research and a review of the literature that many teachers have perceived barriers preventing them from offering environmental education to their students. After identifying the barriers and highlighting the benefits this ten lesson curriculum was created to address the major barriers teachers face when teaching outdoor environmental education and provide students all of the many …

Order And Chaos In The Olivine Underworld: Two Mechanisms For The Formation Of Basal Olivine Layers, James Haddad

Graduate Dissertations and Theses

Recent debate has questioned the efficiency of magma differentiation in basaltic magma chambers (Marsh, 2013). As a result, petrologists are increasingly inclined to interpret olivine cumulate layers in small intrusive bodies as separately injected slurries, as opposed to the result of in-situ differentiation. Two sills with basal olivine layers, the 0601 sill, Victoria Island, NWT, Canada, and the Palisades Sill, Fort Lee, NJ have been examined in detail. First, it can be shown that the 0601 sill could have formed by the emplacement of a single phenocryst bearing magma, followed by settling of the initial phenocryst load, and in-situ differentiation. …

Characterization Of Urban Wetland Vegetation And Management Practices, Megan Anne Larson

Graduate Dissertations and Theses

Urban wetlands are important ecosystems that moderate flooding risks and improve water quality. Vegetation is a key component of urban wetlands; plants promote sedimentation, play critical roles in biogeochemical cycling, and provide food and habitats for other organisms. My research focuses on the standing vegetation and seed banks of urban wetland plant communities. Urban wetlands in south-central New York had a higher percent cover of invasive species in the standing vegetation and significantly lower species richness; however, native species were also common in urban flora. These sites had a high percentage of obligate wetland species, and most closely resembled emergent …

Estimating Live Fuel Moisture In Southern California Using Remote Sensing Vegetation Water Content Proxies, Shenyue Jia, Seung Hee Kim, Son V. Nghiem, Wonhee Cho, Menas Kafatos

Mathematics, Physics, and Computer Science Faculty Articles and Research

Wildfires are a major ecological disturbance in Southern California and often lead to great destruction along the Wildland-Urban Interface. Live fuel moisture has been used as an important indicator of wildfire risk in measurements of vegetation water content. However, the limited field measurements of live fuel moisture in both time and space have affected the accuracy of wildfire risk estimations. Traditional estimation of live fuel moisture using remote sensing data was based on vegetation indices, indirect proxies of vegetation water content and subject to influence from weather conditions. In this study, we investigated the feasibility of estimating live fuel moisture …

Effect Of Informal Settlements On Water Quality, Catherine Achieng Olang, Dwaha Ali Daud, Gouri Raja Gopal

The International Student Science Fair 2018

ABSTRACT

Businesses and other informal settlements have said to be the key of polluters of the Kabuthi River. The population pollutes streams of water, especially Kabuthi River by disposing waste into the rivers. This makes the water unsafe for domestic use by the big slums populations that has to buy water for drinking, cooking, washing clothes and feeding animals yet there is a stream that passes by their homes. The settlements include Gachui, Kwanjiku, Mutuini, Kirigu,Mutego and Waithaka among others.

The study was also set out to establish the key polluters of Kabuthi River by investigating the activities the river …

Nonpoint Source Bacterial Pollution In The Coyote Creek Watershed, Elisabeth Wilkinson

Master's Theses

Nonpoint source pollution is a global challenge affecting streams and rivers. Due to the highly dispersed nature of nonpoint sources, they are difficult to track and manage. The goal of this study was to assess the extent of bacterial pollution along Coyote Creek in Northern California and to provide insight on microwatershed characteristics and their potential correlation to bacteria loads. Samples were collected and analyzed for fecal indicator bacteria concentrations at 21 geographic locations from within the creek and its stormwater outfalls. E. coli levels within Coyote Creek and stormwater entering the creek exceeded recreational water quality standards. Stormwater outfall …

The Impact Of The Deepwater Horizon Blowout On Historic Shipwreck-Associated Sediment Microbiomes In The Northern Gulf Of Mexico, Leila J. Hamdan, Jennifer Salerno, Allen H. Reed, Samantha B. Joye, Melanie Damour

Faculty Publications

More than 2,000 historic shipwrecks spanning 500 years of history, rest on the Gulf of Mexico seafloor. Shipwrecks serve as artificial reefs and hotspots of biodiversity by providing hard substrate, something rare in deep ocean regions. The Deepwater Horizon (DWH) spill discharged crude oil into the deep Gulf. Because of physical, biological, and chemical interactions, DWH oil was deposited on the seafloor, where historic shipwrecks are present. This study examined sediment microbiomes at seven historic shipwrecks. Steel-hulled, World War II-era shipwrecks and wooden-hulled, 19th century shipwrecks within and outside of the surface oiled area and subsurface plume were examined. Analysis …

Examining Livelihoods Shifts Due To Sea-Level Rise Via The Midas (Migration, Intensification, And Diversification As Adaptive Strategies) Model, Andrew Bell

International Congress on Environmental Modelling and Software

Among the myriad impacts of sea-level rise, one set of impacts on livelihoods relates to the shift in freshwater, brackish water, and saltwater agriculture that will be possible in coastal areas. In South and Southeast Asia, Bangladesh and Vietnam are notable in particular for the growth of shrimp aquaculture as an adaptation to changes in salinity. However, while Vietnam has developed a clear and well-attended system of agro-ecological zoning, Bangladesh’s management of salinity is less developed. Conflicts arise among farmers sharing surface water systems over the use of sluice gates and the flow of fresh or salty water, with many …

Simulating Dynamic Drought Adaptation Behaviour Of Agricultural Stakeholders Using Agent-Based Models, Marthe Wens, Mike Johnson

International Congress on Environmental Modelling and Software

Increasing climate variability and changing socio-economic conditions are expected to exacerbate agricultural drought risk in many parts of the world. Current risk assessments, however, do not elegantly incorporate emergent adaptation strategies and therefore fall short in their representation of vulnerability dynamics. Adopting a socio-hydrological framework allows modelers to simultaneously consider the temporal and spatial extents of meteorological and hydrological factors and dynamic human behavior. In our research, we use spatially-explicit agent-based models to investigate how humans respond to perceived drought risk and ultimately impact the hydrological system, in hopes of deriving a clearer understanding of future agricultural drought risk. Agent-based …

Rescaling Drought Mitigation In Rural Sri Lanka, Emily Burchfield, Nicholas E. Williams, Amanda Carrico

Environment and Society Faculty Publications

Smallholder farmers with limited governmental and institutional support often devise innovative strategies to mitigate the impacts of water stress on agricultural production. These drought mitigation strategies can be more culturally and ecologically suitable than top-down, “technocratic,” strategies. Top-down drought mitigation approaches, however, often link farmers with significant infrastructures, financial resources, and specialized knowledge. Successful rescaling of localized mitigation practices can integrate the benefits of localized mitigation with resources available at larger scales. This paper describes the rescaling of a Sri Lankan drought mitigation practice known as bethma. We focus on the process of rescaling, specifically what is lost and …

An Agent-Based Approach To Evaluating Sustainable Drought Adaptation Policy, Mike Johnson, Marthe Wens

International Congress on Environmental Modelling and Software

Droughts are an increasingly prevalent and costly hazard that impact urban populations, agricultural production, and natural ecosystems. As climate becomes more variable, drought-prone regions are working to adapt through policy measures that address the diverse needs of urban centers, irrigation districts, farmers, governments, and NGOs. Developing policy pathways is a useful way to design such drought policies, however, their development requires an understanding of how human and biophysical systems interact and respond to a variety of climate and policy scenarios. In our research, we link a distributed hydrologic model with an agent based model to simulate the emergent, heterogeneous drought …

The Effects Of The Nepal Community Forestry Program On Biodiversity Conservation And Carbon Storage, Harisharan Luintel, Randall Bluffstone, Robert M. Scheller

Economics Faculty Publications and Presentations

Approximately 15.5% of global forest is controlled by ~1 billion local people and the area under community control is increasing. However, there is limited empirical evidence as to whether community control is effective in providing critical global ecosystem services, such as biodiversity conservation and carbon storage. We assess the effectiveness of one example of community-controlled forest, Nepal’s Community Forestry Program (CFP), at providing biodiversity conservation and carbon storage. Using data from 620 randomly selected CFP and non-CFP forest plots, we apply a robust matching method based on covariates to estimate whether CFPs are associated with greater biodiversity conservation or carbon …
