My Encounters With Paradise: The Evolution Of Natural Beauty And Luminist Aesthetics In Central Florida, Jeremy Laplanche Jan 2023

My Encounters With Paradise: The Evolution Of Natural Beauty And Luminist Aesthetics In Central Florida, Jeremy Laplanche

Honors Program Theses

Historically, the marshes and swamps of Central Florida have been depicted as a paradise in artwork by naturalists such as William Bartram and Luminist landscape painters like Martin Johnson Heade. Today, the image of Florida’s tourism centers around theme parks and beaches. However, state parks in Central Florida preserve and restore unique ecosystems. This thesis analyzes the effectiveness of Wekiwa Springs State Park and Blue Spring State Park’s management practices for maintaining the Luminist and naturalist aesthetics. Previous research has identified the role of landscape paintings, particularly from the Hudson River School and the American West, in establishing America’s appreciation …

Land-use planning for modern societies requires technical competence as well as social competence. We therefore propose an integrative solution enabling better land-use planning and management through better-informed decision-making. We adapt a method developed for cross-disciplinary team building to identify the stakeholders and their various objectives and value systems. We use these results to populate artificial societies embedded into a dynamic data analytics framework as a tool to identify, explore, and visualize the challenges resulting from the different objectives and value systems in land-use planning and management. To prove the feasibility of the proposed solution, we present two use cases from …

The Use Of Transport Time Scales As Indicators Of Pollution Persistence In A Macro-Tidal Setting, Guanghai Gao, John J. O'Sullivan, Aisling Corkery, Zeinab Bedri, Gregory M.P. O'Hare, Wim G. Meijer Jan 2023

The Use Of Transport Time Scales As Indicators Of Pollution Persistence In A Macro-Tidal Setting, Guanghai Gao, John J. O'Sullivan, Aisling Corkery, Zeinab Bedri, Gregory M.P. O'Hare, Wim G. Meijer

Articles

An understanding of water exchange processes is essential for assessing water quality management issues in coastal bays. This paper evaluates the impact of water exchange processes on pollution persistence in a macro-tidal semi-closed coastal bay through two transport time scales (TTS), namely residence time and exposure time. The numerical model was calibrated against field-measured data for various tidal conditions. Simulated current speeds and directions were shown to agree well with the field data. By considering different release scenarios of a conservative tracer by the refinement of an integrated hydrodynamic and solute transport model (the EFDC), the two TTS were used …

Quantifying The Economic Costs Of Global Warming, Christopher W. Callahan Jan 2023

Quantifying The Economic Costs Of Global Warming, Christopher W. Callahan

Dartmouth College Ph.D Dissertations

Climate change poses a threat to the well-being of people across the globe. Rising global temperatures will increase the frequency and magnitude of extreme climate events, threatening the lives and livelihoods of vulnerable people. Yet the magnitude and persistence of these economic impacts are poorly understood, making it difficult both to design equitable mitigation and adaptation strategies and to hold emitters accountable for the impacts of their emissions. In this thesis, I combine methods from detection and attribution, climate projection, and causal inference to understand the global economic consequences of past and future climate change. I show that two extreme …

Ancient Bears Provide Insights Into Pleistocene Ice Age Refugia In Southeast Alaska, Flavio Augusto Da Silva Coelho, Stephanie Gill, Crystal M. Tomlin, Marilena Papavassiliou, Sean D. Farley, Joseph A. Cook, Sarah A. Sonsthagen, George K. Sage, Timothy H. Heaton, Sandra L. Talbot, Charlotte Lindqvist

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

During the Late Pleistocene, major parts of North America were periodically covered by ice sheets. However, there are still questions about whether ice-free refugia were present in the Alexander Archipelago along the Southeast (SE) Alaska coast during the last glacial maximum (LGM). Numerous subfossils have been recovered from caves in SE Alaska, including American black (Ursus americanus) and brown (U. arctos) bears, which today are found in the Alexander Archipelago but are genetically distinct from mainland bear populations. Hence, these bear species offer an ideal system to investigate long-term occupation, potential refugial survival and lineage turnover. Here, we present genetic …

Habitat Selection And Habitat Use Of Gray Foxes (Urocyon Cinereoargenteus) On Trespass Cannabis Grows., Haley-Marie R. Jones Jan 2023

Habitat Selection And Habitat Use Of Gray Foxes (Urocyon Cinereoargenteus) On Trespass Cannabis Grows., Haley-Marie R. Jones

Cal Poly Humboldt theses and projects

Trespass cannabis grow sites, otherwise known as illegal cultivation sites on public lands, are extremely hazardous to the environment and can severely impact wildlife movement and behavior. Trespass grow sites are dangerous to wildlife as they negatively impact the quality of habitat and wildlife behavior through habitat modification, pesticide use, discarding of trash, and poaching on national forests. I researched gray fox habitat selection and habitat use at six different grow sites in the Klamath National Forest and Shasta-Trinity National Forest in northwestern California. I deployed GPS collars on three gray foxes at two of those grow sites and three …

Salmon Against Humanity: Are Hatcheries A Part Of Salmon Recovery?, Janine Fong Jan 2023

Salmon Against Humanity: Are Hatcheries A Part Of Salmon Recovery?, Janine Fong

WWU Honors College Senior Projects

Salmon hatcheries have been in place since the late 1800s, but they are controversial parts of salmon recovery. Evidence has been found that hatcheries may be producing weaker fish and harming naturally-occurring populations. However, many of these issues can be addressed with hatchery reforms. There are also external factors to consider, such as the needs of those who depend on salmon and the loss of habitat. In the larger scheme of things, hatcheries appear to be important tools that can be utilized better in order to conserve salmon more effectively. This paper explores the hatchery controversy, from tribal rights to …

Immunofluorescence Visualization Of Polycyclic Aromatic Hydrocarbon Mixtures In The Eastern Oyster Crassostrea Virginica, Kristen M. Prossner, Hamish J. Small, Ryan Carnegie, Michael A. Unger

VIMS Articles

Bivalve mollusks including oysters have low metabolic potential and are therefore susceptible to accumulating high levels of lipophilic organic contaminants such as polycyclic aromatic hydrocarbons (PAHs). Human exposure to PAHs via consumption of this important commercial shellfish can be a serious public health concern in areas where high PAH contamination exists. Previous PAH immunohistochemical studies have been limited to laboratory-based exposures focusing on one or a few individual PAH compounds. To date, such studies have yet to explore PAH accumulation in oysters, known to have some of the highest levels of PAHs across different food products. Using a monoclonal antibody …

Rainwater Catchment System In Public Sector Housing, Araceli Peña, Muhammad Yanzar Sarin

2023 REYES Proceedings

Water is a universal right for all living beings on the planet, but today it has become a commercial good. It costs significantly to extract water from increasingly distant storage sources. For these reasons and many more the fight for water has become increasingly intense. Precisely, an alternative to avoid more dam construction is the implementation of public politic with actions focused on the integral solution of water, that is to say, that it be distributed fairly and equitably to all users, avoiding more concessions to great industries like as soft drinks and breweries, which are the main consumers and …

Thermodynamic Analysis Of Digestate Pyrolysis Coupled With Co2 Sorption, Antonella Dimotta, Cesare Freda Jan 2023

Thermodynamic Analysis Of Digestate Pyrolysis Coupled With Co2 Sorption, Antonella Dimotta, Cesare Freda

Conference papers

To date the management of digestate is a crucial task for anaerobic digestion process. In the present work a strategy for digestate management is thermodynamically analyzed by a commercial software for process simulation called CHEMCAD®. Pyrolysis of digestate is simulated by a minimization of the free Gibbs energy. The sequestration of the carbon dioxide (CO2) released by the pyrolysis is investigated by the addition of calcium oxide, in order to reduce CO2 emissions. The effect of the pyrolysis temperature between 400–900 °C and of the CaO/digestate mass ratio between 0–0.5 was discussed, as well. The CHEMCAD application allowed to investigate …

Lead Program Intern, Eva Araujo

College of the Environment Internship Reports

When I interviewed, Ava and Brandon introduced me to the Miyawaki Method. Their idea was to finish the invasive species removal of a severely overgrown site to the north of campus, and to replant it with an afforestation method which hasn’t yet been used in many places in the United States. It was developed by a Japanese botanist, Dr. Akira Miyawaki. The Miyawaki Method seeks to build a mini-forest, representative of what climatic forests of the natural environment would be like. To start, you build a list of the species which are typically found in an undisturbed forest. Then, you …
