A Gis Assessment Of Ecoregion Representation In Chile's Existing And Proposed Integrated Network Of Protected Areas, Jessica Schutz
Graduate Student Theses, Dissertations, & Professional Papers
Chile's state designated protected areas are reported to show representation bias and to be unable to meet conservation goals. Private protected areas are considered an important tool to resolve these issues, which has led to support for increasing the role of private protected areas in Chile and creating an integrated public-private protected area network. But the validity of the capacity of private protected areas to fix Chile's state protected area network bias, and the advantage of creating an integrated protected area network, have not been assessed. This study uses the most recent data on Chile's state, private, and international protected …

The Economic Impacts Of Forest Pathogens In Washington State: A Hedonic Approach, Logan Blair
All Master's Theses
An increase in the incidence of forest pathogens in the Western US has created new resource management issues. In this research I employ a dataset of 170,141 housing transactions in twelve Western Washington counties to quantify the impacts of parasitic forest damage on the proxy real estate market. Specifically, I estimate a set of hedonic fixed effects models to control for omitted variable bias and spatial autocorrelation. Results show statistically significant impacts on property values in the presence of species specific and aggregate defoliation, suggesting new information for forestry management and policy.

Behavioral Response Of Pacific Lamprey (Entosphenus Tridentatus) To Predator Odors, Laurie L. Porter
All Master's Theses
Pacific lamprey (Entosphenus tridentatus), a species facing serious threats to their existence, experience a number of challenges in reaching their desired spawning grounds during the adult migratory phase, and predators are suspected to be one of these challenges. Understanding if Pacific lamprey respond to predator odorants may provide a management tool for use in conjunction with attractants in guiding lamprey to suitable spawning habitat and deterring them from poor habitat. Previous research has failed to explore Pacific lamprey response to predator odorants, although much research exists on attractant odorants. In our study, we tested Pacific lamprey response to …

Provisioning And Its Effects On The Social Interactions Of Tibetan Macaques (Macaca Thibetana) At Mt. Huangshan, China, Brianna I. Schnepel
All Master's Theses
The dispersal patterns of food resources has a significant effect on the composition of primate groups and social interactions within those groups. Humans often alter the dispersal of food. Non-humans often use affiliative behaviors to elicit tolerance or support from other group members. I investigated whether provisioned food resources alter the social interactions and group dynamics of Macaca thibetana. All-occurrence sampling and scan sampling were used for data recorded by camera traps. Trail-cameras were placed at six locations that contain natural and human food resources and recorded 60-second videos. Social behavior and proximity of the monkeys were recorded. I …

An Appraisal Of Experiences Of Climate Change And Adaptive Response To Heat Stress By Farmers In Rural Ghana, Kwasi Frimpong
Theses: Doctorates and Masters
With the increase in average global temperatures, heat-related illnesses and deaths have unfolded as occupational and health issues. Periods of high to extreme temperatures are becoming more common and are a leading cause of weather-related deaths in many countries. In agricultural settings of African countries, heat stress is a major concern as many smallholder farmers work outdoors with limited access to cooling systems even in their resting and living environments. This study, conducted in the Bawku East part of Northern-East Ghana in 2013, examines, in the context of climate change, the trends and impacts of heat stress on smallholder farmers, …
Carbon Storage And Preservation In Seagrass Meadows,

Edith Cowan University
Carbon Storage And Preservation In Seagrass Meadows, Mohammad Rozaimi Jamaludin
Theses: Doctorates and Masters
Seagrass meadows are important ‘Blue Carbon’ sinks but many questions remain unaddressed in regards to the organic carbon (OC) sequestration capacity and processes leading to retention and persistence of OC in seagrass sediments. The research summarised in this dissertation examined 37 sediment cores from twelve Australian seagrass meadows (Posidonia australis and Halophila ovalis) in order to improve our understanding of OC storage and preservation in seagrass sediments. The research: quantified the OC storage in seagrass meadows and the reduction in stores after ecosystem degradation; the rates of OC accumulation; the roles of species composition and the depositional nature …

A Basic Guide For Empirical Environmental Social Science, Michael Cox
Dartmouth Scholarship
In this paper, I address a gap in the literature on environmental social science by providing a basic rubric for the conduct of empirical research in this interdisciplinary field. Current literature displays a healthy diversity of methods and techniques, but this has also been accompanied by a lack of consistency in the way in which research in this area is done. In part this can be seen as resulting from a lack in supporting texts that would provide a basis for this consistency. Although relevant methods texts do exist, these are not written with this type of research explicitly in …

Eco-Design Integration Into New Product Development Processes: Comparison Between Lca Software And Cad-Integrated Tools, Maria I. Hernandez Dalmau
Purdue Polytechnic Masters Theses
The constant growth of environmental concerns and in order to satisfy the increasing population demands, designers have started to integrate eco-design parameters in early design stages. The technological development that happened in the last decade has started to integrate LCA methods within CAD tools, allowing non-geometric data to be integrated in a typical geometrical model. The main research interest of this thesis is focused on the evaluation of the use of these emerging CAD tools, as tools capable to evaluate the futures environmental impacts of products and processes. This thesis studies through three comparative case studies if SolidWorks Sustainability as …

The Effects Of Insecticide Dose And Herbivore Density On Tri-Trophic Effects Of Thiamethoxam In A System Involving Wheat, Aphids, And Ladybeetles, Michael M. Bredeson, R Neil Reese, Jonathan G. Lundgren
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
We assess how herbivore density and insecticide dose affects the tri-trophic interactions among thiamethoxam-treated wheat (Triticum sp.), Rhophalosiphum padi and the predatory Coleomegilla maculata DeGeer. In the first experiment 2nd and 4th instar C. maculata were fed aphids reared for 24 h on wheat plants treated with sub-lethal thiamethoxam soil drenches to assess the effect of insecticidal dose on the predator. In the second experiment a constant, sub-lethal thiamethoxam soil drench was used on wheat plants, but the plants were infested with different densities of aphids. Aphids from each density treatment were then fed to C. maculata 2nd instars. Insecticide …

May You Walk In Beauty: The Decline Of Navajo Land And Culture, Jocelyn Catterson
Undergraduate Theses, Professional Papers, and Capstone Artifacts
The Navajo homeland, Dinetah, is bordered by four mountains that are sacred to the Navajo people: two in Colorado, one in New Mexico, and one in Arizona. Historically, Navajo medicine men have traveled to these mountains to renew prayers and collect medicinal herbs. Today, the mountains, which exist outside of the reservation boundaries, are used for resource extraction and various recreational pursuits. While many Navajo are fighting for the protection of these sacred lands and their traditional culture, others are disinterested. Traditional practices and beliefs are slowly disappearing within the Navajo Nation. The land-use issues associated with these sacred mountains …

Crop Swap Missoula: Food Waste And The Sharing Solution, Cathryn Raan
Undergraduate Theses, Professional Papers, and Capstone Artifacts
Rachel Botsman coined the term “collaborative consumption” to describe an economic model based on sharing, swapping, trading, or renting products and services, and enabling access rather than ownership1. Also referred to as the sharing economy, the mesh economy, or the peer-to-peer economy, collaborative consumption models offer a more efficient use of unused, or underutilized resources. Whereas previously peer-to-peer exchanges were only practical within small networks of friends, family, and neighbors, the Internet and mobile technology have allowed us to share almost anything at any time. While there are countless examples of community exchange platforms, and more springing up …

Understanding Vulnerability In Alaska Fishing Communities: A Validation Methodology For Rapid Assessment Of Well-Being Indices, Conor M. Maguire
All Master's Theses
Social well-being indices measure how fishing communities are likely to be affected by social-ecological perturbations, and are a significant tool to identify the primary issues influencing communities’ sustained participation in fishing activities. In an attempt to further our understanding of how communities are affected by such perturbations, we have developed a rapid assessment methodology to test the external validity of a set of well-being indices that measure community vulnerability. This methodology informs how well such indices reflect the communities they represent by measuring elements of well-being through field observations, and comparing them to corresponding index components created from secondary data …

Gleaning In The Cedar Valley: A Post-Evaluation Study, Dylan Thomas Hillyer
Honors Program Theses
Gleaning is a term describing the act of either picking, cleaning or sorting produce that would otherwise be wasted. It is a practice long known to Europe, and in the past thirty years has gained immense popularity among non-profit organizations throughout the United States. The Cedar Valley Gleaning Program (CVGP) had its pilot-year in the fall of 2014. This thesis seeks to improve the efficacy of the CVGP through examining both the pilot year, and a qualitative study of gleaning operations worldwide, to answer the question: How can gleaning become an effective tool for communities in the Cedar Valley.

Intra- And Inter-Seasonal Variability Of Supra-Glacial 1 Streams And Lakes Over The West Greenland Ice Sheet 2 From High-Resolution Satellite Optical Data, Michael Gregory Brown
Dissertations and Theses
The Greenland ice sheet (GrIS) is one of the largest glacial ice masses on Earth, second only to the Antarctic ice sheet. The surface hydrology of the GrIS plays a crucial role on the surface energy and mass balance budgets of the ice sheet as a whole. Surface water, known as supra-glacial water, is seasonally found in the ablation zone and feeds the en-glacial and sub-glacial hydrological environments of the ice sheet. The spatial distribution of surface streams is poorly understood and their temporal variability is (to our knowledge) unknown. One of the reasons for the lack of knowledge on …

Coastal Environmental Policies And Water: Environmental Values In Ghana And Senegal, Molly R. Loftus
CMC Senior Theses
This thesis provides a comparative analysis of the environmental values present in Ghana’s and Senegal’s coastal regions, and the implications that those have for the surrounding environment. The countries approaches to urban farming, mining and oil and gas extraction, fishing, marine debris and municipal waste management are assessed in order to reach a greater understanding of these environmental issues. In undertaking this thesis, I attempted to draw a correlation between the handling of these issues and how people perceive their environment. Through the comparison of environmental degradation and the level of effort to achieve a more sustainable developmental framework in …

The Political Economy Of Environmental Justice: A Comparative Study Of New Delhi And Los Angeles, Ratik Asokan
CMC Senior Theses
Though mainstream environmentalism, both in the U.S. and India, was initially rooted in social justice, it has, over time, moved away from this focus. The Environmental Justice Movement consequently arose to reunite social and environmental activism. In this thesis, I trace the historical relationship between the mainstream environmentalism, the Environmental Justice Movement, and marginalized communities. After providing this general overview, I examine two case studies – in Los Angeles and New Delhi respectively – where marginalized communities have been involved in Environmental Justice activities. My analysis reveals that marginalized communities often act in an ‘environmentalist’ or ‘environmentally friendly’ manner, without …
