Integrating Traditional Ecological Knowledge With Modern Day Ecosystem Management And Restoration Practices, Leialani O. Hufana

Master's Projects and Capstones

Traditional ecological knowledge (TEK) is a fairly new area of research that can supplement science research and modern day ecosystem management practices. Indigenous cultures and local communities have been using and passing on TEK in forestry, agricultural, and aquaculture/marine ecosystem management. Through a review of literature, TEK in Hawaiʻi was compared to TEK in other countries. TEK was also compared to modern day ecosystem management practices to determine if TEK could be integrated. In Hawaiʻi an ahupuaʻa, a land transect that cuts the islands in sections from mountain to sea, was an integrated watershed based management system. TEK in ahupuaʻa …

Evaluation Of Mangrove Ecosystem Restoration Success In Southeast Asia, Penluck Laulikitnont

Master's Projects and Capstones

Many restoration efforts have been implemented recently to offset the rapid degradation of mangrove ecosystem worldwide, especially in Southeast Asia where the largest area of mangrove ecosystem can be found. Two primary approaches used for mangrove ecosystem restoration include the plantation approach and the ecological mangrove restoration (EMR) approach. Monoculture plantation is the most common technique used in plantation approach, which usually results in low species diversity. The EMR approach on the other hand, focuses on correcting the hydrology of restoration sites first. Planting can be used as part of the adaptive management process if mangrove seedlings and propagules do …

LSU New Orleans Theses and Dissertations

In 2005, Hurricane Katrina’s diverse impacts on the Greater New Orleans area included damaged and destroyed trees, and other despoiled vegetation, which also increased the exposure of artificial and bare surfaces, known factors that contribute to the climatic phenomenon known as the urban heat island (UHI). This is an investigation of UHI in the aftermath of Hurricane Katrina, which entails the analysis of pre and post-hurricane Katrina thermal imagery of the study area, including changes to surface heat patterns and vegetative cover. Imagery from Landsat TM was used to show changes to the pattern and intensity of the UHI effect, …

The Potential For Marine Protected Areas In The San Francisco Bay, Samantha P. Delapena

Master's Projects and Capstones

The San Francisco Bay (the Bay) is the largest estuary on the Pacific Coast. This makes it one of country's greatest natural resources. Historical and current impacts from mining, pollution, and dredging have reduced the size of the Bay’s shallow, productive environment, which provides vital habitat for many important species. The seven and a half million people that inhabit the shores and hills surrounding the Bay, and economic activities such as commercial fishing and development continue to degrade ecosystems. Although conservation efforts have led to improvement of water quality and some habitat restoration over the past few decades, very little …

Harvest Incentives: A Tool For Managing Aquatic Invasive Species, Bob Wiltshire, Nathan Stone, Marshall Meyers, Bill Hyatt, Lori Williams, Jason Goldberg, Susan Pasko, Leah Elwell

National Invasive Species Council

Conclusion

The success of any harvest incentive program to address aquatic invasive species will depend upon numerous biological, socioeconomic, and legal considerations. Programs that encourage harvest may be a successful management tool in targeting small, distinct populations; in high priority areas within a larger invasion; or they may play a supplementary role within larger control programs. Their use, however, will require careful review, planning, and monitoring to ensure success and that they do not unintentionally lead to further spread of invasive species, cause additional harm to native species, or waste valuable resources.

Carbon Sequestration In Tidal Salt Marshes And Mangrove Ecosystems, Carlos Eduardo Quintana-Alcantara

Master's Projects and Capstones

Wetlands are dynamic systems that provide support to vital environmental functions and services. Wetlands take part in the global carbon cycle by holding organic carbon in biomass, soils and sediments. In recent years, the wetland carbon sequestration capacity has been researched worldwide due to the increase of the concentrations of greenhouse gasses implicated in global warming and climate change. Although coastal wetlands release the greenhouse gasses carbon dioxide, methane and nitrous oxide, these ecosystems maintain high performance in offsetting significant amounts of atmospheric carbon. This paper investigated the carbon sequestration capacity of coastal wetland ecosystems summarizing the environmental conditions and …

Recovery Of Oregon Coast Coho Salmon (Onchorhynchus Kitsutch) Through Restoration Of Freshwater Habitats, Andrew P. Lutz

Master's Projects and Capstones

Methods of dendrochronology by means of incremental coring

have been refined in this study for specific use in northern

California riparian floodplains. Little information is available

on riparian dendrochronology because of the challenges of

analyzing riparian tree species. Three dominant tree species

(Alnus rubra, Umbellularia californica, Acer macrophyllum)

in the floodplain of Redwood Creek were evaluated for the

relationship between age and diameter at breast height (DBH)

using a least squares linear regression analysis. Through this

study, complications with analysis for the riparian tree species

led to a more thorough investigation as to enhancing core

quality and annual growth ring …

Eating Misery: The Moral Question Of Factory Farming And The Struggle With Affected Ignorance, Victoria Elizabeth Oh

2014 Student Theses

What moral responsibility do we have to the suffering that we cause to animals? Should we reconsider our socially accepted treatment of animals in agriculture? In this essay I attempt to explore those moral questions by comparing new agriculture to the past; quantitative data linking environmental concerns to animal agriculture; and the current policy and law relating to factory farming. Using this information I try to unpack our moral obligation to these animals in factory farms and our affected ignorance to the entire subject of the unethical treatment of animals in factory farms. I recommend that we need to transform …

The Atlantic Bluefin Tuna: A Tragedy Of The Commons On The High Seas, Janice G. Boswell

2014 Student Theses

Considered the biggest threat to marine ecosystems today, it is estimated that three fourths of the world’s fish stocks are being harvested faster than they can reproduce. Because the ocean is not subject to defined property rights, there exists a “race to the bottom” encouraged by the rise of industrial fishing, as well as a voracious global demand. The Atlantic bluefin tuna provides a glaring example of an overfished species on the brink of extinction due to its popularity in the Japanese market. Its rarity and esteem have made it the most expensive fish in the sea and policy has …

Got Milk?: Exploring The Truth Behind America’S Drink And Nature’S Perfect Food, Andora Leung

2014 Student Theses

The product of milk is a staple to American culture and diet. Described as the “perfect food,” this notion has been ingrained through decades of misleading information as well as persuasive marketing and advertisement implemented by government officials and industry leaders. However as health risk rise, questions concerning the validity of milk calorie and nutritional value, the use of bovine growth hormone (rBGH) and subtherapeutic antibiotics rise as well. In my thesis paper, I will study the history of the dairy industry and how their agenda quickly transitioned from the benefit of the customer to the benefit of the industry. …

A Decrepit New York: Synthesizing New York’S Infrastructure Problems, Connor Farrell

2014 Student Theses

Coastal living has become a very popular, often fantasized, way of life. This lifestyle is easy, relaxing, and, above all, it soothes the stress. However, mankind’s innate desire to live near America’s oceans, rivers, and other bodies of water have allowed its population to become vulnerable to super storms. Super storms, such as Hurricane Sandy, have become more prevalent over recent years, and America needs to take into account the massive population whom call the East coast home. Focusing in on the New York area, I will be able to show how our thoughtless designs and locations of towns/cities have …

The use of plastic is prevalent in our society due to the increasing amount of new products entering the market that need some form of packaging that is solid enough yet disposable. From everything to yogurt containers to diapers, plastic containers are a large part of our society’s consumption culture and often goes unnoticed. However, people point to plastic water bottles and containers as the only culprit, and often times forget that almost all packaging contains some form of plastic. For my thesis I want to examine how the use of plastics has increased waste material, considering that it takes …

A Flaw In The Design: American Sprawl And Climate Change, Gregory Behl

2014 Student Theses

The physical landscape of the United States has developed to a point that it has become detrimental to the health of its citizens and the natural environment. Designed around abundant fossil fuels, the sprawling panorama Americans call home has significantly contributed to a decline in global ecosystem services. Using historical precedence as a guide for the constant improvement of surrounding environs has led to the nation’s exorbitant resource use and beyond sustainable emissions rates required by the physical design of the man-made landscape. These mandates, embodied in a physical design, further reinforce isolation and contribute to the psychological denial about …

Water Water Everywhere: Analyzing Long Island's Water Issues And Finding Solutions For A Sustainable Future, Anthony T. Becker

2014 Student Theses

Over three million people call Long Island their home. With access to beautiful landscapes, world-renowned beaches, and proximity to New York City, it is no wonder that so many proudly call this geographic stretch of glacial till their home. However, throughout the years our actions do not necessarily reflect this affection we have to our home. Years of sprawl and human infestation across the island have resulted in widespread environmental degradation. Specifically, the water we drink and the beaches we enjoy have become endangered. I plan on studying the urban ecology of how intensified population growth led to the eutrophication …

The Restorative Effects Of Natural Decor, Tobias Burnham

Department of Environmental Studies: Undergraduate Student Theses

Humans are continually opting to live in urban environments, furthering us from the innate connection to the natural environment we have evolved with over millennia. These urban settings place several stressors on us in the form of stimuli that requires directed attention (cars, billboards, traffic lights, etc.) in which deplete our attentional resources leading to Direct Attention Fatigue (DAF). Attentional Restoration Theory (ART) is based on the ability of natural environments to have restorative effects on these depleted resources due to the relative ease of experiencing nature through involuntary attention. The focus of this study is to determine how nature-based …
