Measurement Of The Ocean Economy From National Income Accounts To The Sustainable Blue Economy, Charles S. Colgan
Journal of Ocean and Coastal Economics
The widespread efforts to incorporate the economic values of oceans into national income accounts have reached a stage where coordination of national efforts is desirable. A symposium held in 2015 began this process by bringing together representatives from ten countries. The symposium concluded that a definition of core ocean industries was possible but beyond that core the definition of ocean industries is in flux. Better coordination of ocean income accounts will require addressing issues of aggregation, geography, partial ocean industries, confidential, and imputation is also needed. Beyond the standard national income accounts, a need to incorporate environmental resource and ecosystem …

Northern San Francisco Bay Ecological Risk Assessment: Potential Crude By Rail Incident, Meagan Bowis
Northern San Francisco Bay Ecological Risk Assessment: Potential Crude By Rail Incident, Meagan Bowis
Master's Projects and Capstones
Oil spill models, ecological risks, response options, and costs were assessed for a discharge of Bakken crude oil into the Northern San Francisco Bay from a train derailment. This assessment was based on the risk of crude by rail derailments into the San Francisco Bay; in 2014, California oil refineries imported over 240 million gallons of Bakken crude oil by rail for processing. A hypothetical scenario was developed from a derailment on the Union Pacific Railroad Bridge and discharging 100,000 gallons of Bakken crude oil into the Northern San Francisco Bay. The oil trajectory impacted the Carquinez Strait, Suisun, San …

Dartmouth Scholarship
We review and synthesize information on invasions of nonnative forest insects and diseases in the United States, including their ecological and economic impacts, pathways of arrival, distribution within the United States, and policy options for reducing future invasions. Nonnative insects have accumulated in United States forests at a rate of ~2.5 per yr over the last 150 yr. Currently the two major pathways of introduction are importation of live plants and wood packing material such as pallets and crates. Introduced insects and diseases occur in forests and cities throughout the United States, and the problem is particularly severe in the …
Development Of A Decision Support System For Post Mining Land Use On Abandoned Surface Coal Mines In Appalachia, Matthew Zimmerman
Development Of A Decision Support System For Post Mining Land Use On Abandoned Surface Coal Mines In Appalachia, Matthew Zimmerman
Sustainability and Social Justice
Decision support systems are diverse and have been used to solve multiple problems ranging from the complex to the simple. With the complexity of environmental decisions today, these systems provide a logic based approach to evaluating and choosing environmental solutions. Abandoned mining lands (AML) are an issue for the environment in the Appalachian region. Given this a decision support system was designed using previously created frameworks and indices from other systems created. The system is comprised of two main sections, selecting the ideal post-mining land-use (PMLU), and maximizing the potential of land to be reclaimed under budgetary constraints. This system …

Cockatoo Sands In The Victoria Highway And Carlton Hill Areas, East Kimberley: Hydrogeology, Aquifer Properties And Groundwater Chemistry, D L. Bennett, John Andrew Simons, Richard J. George Dr, Paul Raper
Resource management technical reports
Cockatoo Sands are recognised as potentially suitable for irrigated agriculture because they are generally well drained and not subject to waterlogging or inundation. These characteristics allow them to be cultivated and prepared for planting various crops during the wet and dry seasons of northern Australia. Expanding agricultural production onto the Cockatoo Sands around Kununurra will increase opportunities for agriculture by increasing the overall scale of agriculture, allowing year-round agricultural enterprise, new crops and new market opportunities.
DAFWA has assessed the soil characteristics and agriculturally suitable areas of Cockatoo Sands in the Victoria Highway and Carlton Hill areas near Kununurra. Potential …
Gaur (Bos Gaurus) Abundance, Distribution, And Habitat Use Patterns In Kuiburi National Park, Southwestern Thailand, Supatcharee Tanasarnpaiboon
Gaur (Bos Gaurus) Abundance, Distribution, And Habitat Use Patterns In Kuiburi National Park, Southwestern Thailand, Supatcharee Tanasarnpaiboon
School of Natural Resources: Dissertations, Theses, and Student Research
Population status of gaur (Bos gaurus), a wild cattle, in most habitats where they are present, is still unknown. As the use of camera traps in wildlife studies are widespread, I developed photographic individual identification procedures and utilized encounter histories of gaur individuals from camera trap data to estimate gaur abundance and density using the spatially explicit capture-recapture analysis. The study was conducted at Kuiburi National Park, southwestern Thailand, comprised of dry evergreen forest, moist evergreen forest, and man-modified secondary forest during November 2013- January 2015. I conducted 71 direct observations in a savannah-like habitat area to observe …
A Plan For Pollinator Landscape Management On The Ursinus Campus, Megan N. Hanscom
A Plan For Pollinator Landscape Management On The Ursinus Campus, Megan N. Hanscom
Environment and Sustainability Honors Papers
Due to increased pollinator decline over the past decade, colleges and universities are developing pollinator management plans to help combat pollinator loss. Pollinators, and more specifically bees, are vital members of local ecosystems and protection efforts are greatly needed. This plan was created to address the needs of Ursinus College pollinators using relevant suggestions from pollinator research and existing protection plans. This plan includes suggestions for increased pollinator habitat on campus, ways to reduce pollinator stressors, and ways that the Ursinus community can positively impact pollinator health.
Chemical And Physical Characteristics Of Rivers Above And Below Four Hydroelectric Power Facilities In The Chiriquí Viejo And Chico Watersheds Of Chiriquí, Panama, Tricia Light
Independent Study Project (ISP) Collection
The advance of anthropogenic climate change and human energy use has sparked unprecedented international interest and investment in fossil fuel free energy sources such as hydroelectric power. Extensive construction of hydroelectric power facilities has occurred in Panama in recent years, particularly in the westernmost Chiriquí province. Hydroelectric power, especially that generated by relatively small facilities, is generally thought to be a “clean” alternative energy source with few negative environmental consequences. Some evidence suggests, however, that even small facilities can have significant ecological impacts on rivers. This study investigated river properties above and below four small hydroelectric facilities on the Chiriquí …

Behavioral Responses And Policy Evaluation: Revisiting Water And Fuel Policies, Shanxia Sun
Behavioral Responses And Policy Evaluation: Revisiting Water And Fuel Policies, Shanxia Sun
Open Access Dissertations
In my dissertation, I examine how policies regulating agricultural production and clean technology impact the environment. I focus on policies affecting water depletion, water pollution, and fuel consumption. I assess their cost-effectiveness by modeling and quantifying the behavioral responses of farmers and households.
My first essay focuses on decreasing groundwater depletion through increasing irrigation efficiency in Mexico. I quantify the impacts of different sources of inefficiency on groundwater extraction, and I evaluate the effectiveness of alternative policies that aim to reduce the over-extraction of groundwater. I find that mechanisms of electricity cost-sharing implemented in many wells have a sizable impact …

Wildlife Underpasses: Frequency Of Use By Neotropic Mammals In Parque Natural Metropolitano, Panamá City, Panamá, Kelly Russo
Wildlife Underpasses: Frequency Of Use By Neotropic Mammals In Parque Natural Metropolitano, Panamá City, Panamá, Kelly Russo
Independent Study Project (ISP) Collection
In a world of ever increasing globalization and urbanization, roads present wildlife with a number of challenges. They fragment habitats, disrupt animal movements, impact reproductive success and the fitness of individuals and populations, alter population dynamics, and cause unnatural levels of mortality. Fortunately, the numerous detrimental effects of roads can be alleviated by the proper implementation of mitigation structures, such as underpasses, sky bridges and vegetated overpasses. These mitigation structures are an important source of genetic connectivity, especially in a peri-urban reserve setting. This study seeks to understand what species of mammal utilize the wildlife underpasses below Via La Amistad, …

Environmental Variables Affecting The Performance Of Large-Scale Solar Photovoltaic Power Plants, Parikhit Sinha
Climate Sustainability Lecture Series
The environmental sciences have been critical to identifying global environmental challenges such as climate change, but they have been less extensively utilized in deploying solutions to those challenges, such as solar energy. Environmental variables such as temperature, humidity, aerosols, clouds, soiling, and snowfall have important effects on solar PV performance, and these effects can vary regionally. The current status of large-scale solar PV deployment will be discussed along with the role of environmental variables on PV performance.

Powering The Planet: The Role Chemistry Plays In Solar Energy Technology, Amy M. Scott
Climate Sustainability Lecture Series
Global energy demands are projected to double by 2050, according to the U.S. Department of Energy, and solar energy has the greatest potential as the most benign, universal resource for generating electricity. However, harnessing the solar energy efficiently and converting it towards useful forms of power that are compatible with our current infrastructure remains an elusive goal. Today’s solar energy utilization relies on silicon-based photovoltaic (PV) technology, which converts photon energy to electrical energy. The efficiency of these devices remains low (< 30%) and the cost of processing silicon and installing solar panels in homes makes PV uneconomical compared to the current price of electricity. Research efforts towards developing new inorganic and organic materials for thin film PV to replace silicon are currently underway. Organic materials are particularly interesting from the standpoint of developing simple, cheap materials that can be easily tailored for future PV devices. The future of solar energy utilization relies on developing solar paints for vehicles, solar shingles for rooftops, and spray-on solar ink for small device applications, but continued fundamental research is needed for decreasing cost and improving efficiency for next generation devices.

Spatial Analysis Of Forest Crimes In Mark Twain National Forest, Missouri, Karun Pandit, Eddie Bevilacqua, Giorgos Mountrakis, Robert W. Malmsheimer
Spatial Analysis Of Forest Crimes In Mark Twain National Forest, Missouri, Karun Pandit, Eddie Bevilacqua, Giorgos Mountrakis, Robert W. Malmsheimer
Journal of Geospatial Applications in Natural Resources
Forest crime mitigation has been identified as a challenging issue in forest management in the United States. Knowledge of the spatial pattern of forest crimes would help in wisely allocating limited enforcement resources to curb forest crimes. This study explores the spatial pattern of three different types of forest crimes: fire crime, illegal timber logging crime, and occupancy use crime in the Salem-Patosi Ranger District of Mark Twain National Forest. Univariate and bivariate Ripley’s K-functions were applied to explore the spatial patterns in crime events, like clustering and attraction among forest crime types. Results reveal significant clustering for each forest …

Comparison Of Terrain Indices And Landform Classification Procedures In Low-Relief Agricultural Fields, Derek A. Evans, Karl W. J. Williard, Jon E. Schoonover
Journal of Geospatial Applications in Natural Resources
Landforms control the spatial distribution of numerous factors associated with agronomy and water quality. Although curvature and slope are the fundamental surface derivatives used in landform classification procedures, methodologies for landform classifications have been performed with other terrain indices including the topographic position index (TPI) and the convergence index (CI). The objectives of this study are to compare plan curvature, the convergence index, profile curvature, and the topographic position index at various scales to determine which better identifies the spatial variability of soil phosphorus (P) within three low relief agricultural fields in central Illinois and to compare how two methods …
Discordant Data And Interpretation Of Results From Wildlife Habitat Models, Anita T. Morzillo, Michael G. Wing, Justin Long
Discordant Data And Interpretation Of Results From Wildlife Habitat Models, Anita T. Morzillo, Michael G. Wing, Justin Long
Journal of Geospatial Applications in Natural Resources
Wildlife habitat management is an important part of natural resource management. As a result, there are a large number of models and tools for wildlife habitat assessment. A consequence of the many assessment tools is inconsistency when comparing results between tools, which may lead to potential confusion management decisions. Our objective was to compare results from two wildlife habitat models – one being relatively coarse (HUC5) scale and not spatially dynamic and the other being finer scale spatial data based on a 30 m spatial resolution –for habitat assessment of three species across the West Cascades of Oregon: Northern spotted …

Methane Emissions As Energy Reservoir: Context, Scope, Causes And Mitigation Strategies, Xiaoli Chai, David J. Tonjes, Devinder Mahajan
Technology & Society Faculty Publications
Methane (CH4) is now considered a bridge fuel between present fossil (carbon) economy and desired renewables and this energy molecule is projected to play an important role in the global energy mix well beyond 2035. The atmospheric warming potential of CH4 is 28-36 times, when averaged over a 100-year period, that of carbon dioxide (CO2) and this necessitates a close scrutiny of global CH4 emissions inventory. As the second most abundant greenhouse gas (GHG), the annual global CH4 emissions were 645 million metric tons (MMT), accounting for 14.3% of the global anthropogenic GHG emissions. Of this, five key anthropogenic sources: …
Ex-Situ Conservation Programs: Worthwhile?, Nicolette Sliwa, Aaron Sieve
Ex-Situ Conservation Programs: Worthwhile?, Nicolette Sliwa, Aaron Sieve
Biology: Student Scholarship & Creative Works
The effectiveness of conservation programs was researched, specifically within zoos, and their attempts to repopulate areas with captive-born individuals of endangered species. There are major biological and economic concerns with these programs focused on, including potential genetic adaptation to captivity, effects of inbreeding, and if this is a truly worthwhile use of funds to restore a species. Looking at the black-footed ferret, the whooping crane, and other supposed successful captive-breeding programs, it is explored whether reintroduced individuals thrive in their new habitats sufficiently enough to contribute to the restoration of the species, and more broadly, their ecosystems.

Marine species with planktonic larvae often have high spatial and temporal variation in recruitment that leads to subsequent variation in the ecology of benthic adults. Using a combination of published and unpublished data, we compared the population structure of the salt marsh snail, Littoraria irrorata, between the South Atlantic Bight and the Gulf Coast of the United States to infer geographic differences in recruitment and to test the hypothesis that the Deepwater Horizon oil spill led to widespread recruitment failure of L. irrorata in Louisiana in 2010. Size-frequency distributions in both ecoregions were bimodal, with troughs in the distributions consistent …
