Using Particle Size Analysis To Separate The Deposition Of A Bonebed And Artifact At The Wenas Creek Mammoth Site, Genevieve Brown

All Master's Theses

The 2005 discovery of a 17,000 year old mammoth bonebed in close proximity to a possible artifact at the Wenas Creek Mammoth Site (WCMS) brought with it the question of whether the bones and artifact were actually deposited together. If the two are associated, the WCMS would qualify as a Pre-Clovis site, a title given to just a handful of proven archaeological sites in North America, though claimed for numerous more. A close interval particle size analysis was performed on 2 column samples from the WCMS with the intention of identifying microstratification that would separate the bonebed from the artifact. …

Washington's Fish Consumption Rate And Water Quality Standards: Fostering Allies To Keep Our Seafood Clean, Tiffany J. Waters

All Master's Theses

Washington State’s current fish consumption rate and water quality standards update has been a highly contentious public policy debate between Washington State tribes, the State of Washington’s Department of Ecology, the Federal Environmental Protection Agency, and many prominent Washington State industries. Environmental groups and Washington tribes have partnered in the Keep Our Seafood Clean Coalition to educate the public on the need for increasing water quality standards to protect tribal and public health. My research includes analyzing Washington's tribal/State agency co-management relationships, the water quality standards history and current criteria, and the narratives of the public debate; and conducting interviews …

Interpretation Of Shell [Delta]180 And [Delta]13c From Two Hells Canyon Study Sites: A Methods Approach To Analysis, Nathaniel Jacob Morse

All Master's Theses

I analyze stable oxygen isotope ([delta]180) and stable carbon isotope ([delta]13C) data from shell at two study sites in the Hells Canyon in Oregon and Idaho. Mussel shell isotope data from two species, Margaritifera falcata and Gonidea angulata, are compared with a terrestrial snail species Oreohelix strigosa from the Tryon Creek site (35WA288) and the Bernard Creek Rockshelter (1 0IH483). There were five methodological hypotheses to test with these data. Three tests yielded no significant correlation in isotope values: M falcata vs. G. angulata, mussels vs. snails, and winter vs. summer increments of snails. A fourth test showed …

Elk And Deer Hunters In Washington State: Affiliations And Ethical Behavior, Isa O. Harrison

All Master's Theses

Elk and deer are particularly challenging natural resources to manage due to their mobility and the impacts of other species and humans both direct and indirect. A man-made lack of natural predators has created a need for hunting in order to control the population expansions of herds. Such efforts face two major problems: mobility makes herds difficult to accurately quantify and hunting laws are challenging to enforce. Policies regarding the annual take and type of hunting have been based on the assumption that the primary factor motivating hunters is harvesting more animals. However, this study has found that the primary …

Influence Of Saltwater Intrusion, Climate, And Development On The Ground Water Supply Of San Juan Island, Scott Joel Adolphson

All Master's Theses

Freshwater availability is a serious resource concern, due to the needs of its increasing population. This issue is especially critical in coastal regions, both due to supplying the growing number of people migrating to these areas and the higher potential for saltwater intrusion into groundwater supplies as water demands increase. This study assessed the degree of saltwater intrusion on San Juan Island, Washington, including its extent, contributing factors and the implication for the water resource availability. Results indicate that saltwater intrusion levels have not increased significantly in the study area, yet the size of the area threatened has increased. Saltwater …

The Action Cycle/Structural Context Framework: A Fisheries Application, D. G. Webster

Dartmouth Scholarship

There is a growing consensus that environmental governance is a wicked problem that requires understanding of the many linkages and feedbacks between human and natural systems. Here, I propose an action cycle/structural context (AC/SC) framework that is based on the concept of responsive governance, in which individuals and decision makers respond to problems rather than working to prevent them. By linking agency and structure, the AC/SC framework points out two key problems in the realm of environmental governance: the profit disconnect, whereby economic signals of environmental harm are dampened by endogenous or exogenous forces, and the power disconnect, whereby those …

Evaluating And Prioritizing Stream Restoration In Mined Appalachian Watersheds., Eric Mitchell Miller

Graduate Theses, Dissertations, and Problem Reports (ETD)

The state of West Virginia requires stream mitigation to offset anthropogenic impacts to streams; consequently there is a high concentration of mitigation projects in the mountaintop mining/valley fill region. Projects are typically outside mine boundaries and sites are selected at the discretion of the West Virginia Department of Environmental Protection. This dissertation evaluated current in-stream, natural channel design (NCD) structures and prioritized future project locations. First, we assessed the Little Coal River, which is one of the largest physical restoration projects in the state. The Little Coal drains 994 km2 with extensive historic and contemporary coal mining. The objectives of …

Ensuring Our Future Or Sowing The Seeds Of Our Own Destruction? Crop Insurance And Water Use In Texas, Michael Shapiro

Pomona Senior Theses

Agriculture is the largest consumer of water in the United States. Policies that affect agriculture therefore have the potential to have a large effect on the overall use of water. Crop insurance is one such policy, which was found to significantly increase water use in the state of Texas. Much, but not all of this effect can be explained by an increase in planting density, and results vary widely by crop and by region.

A Botanical Survey Of Native And Non-Native Species Along The Three Rivers Greenway In Columbia, South Carolina, Rebecca L. Givens

Theses and Dissertations

Baseline surveys are important tools in establishing the present flora located within an area for future monitoring. In addition, knowledge of invasive species presence is essential to help maintain native ecosystem biodiversity. This study aimed to establish a baseline inventory of plant species found along a portion of the Three Rivers Greenway in Columbia, South Carolina, and to create a comprehensive list of native and invasive plant species within this area. In addition, a geographic information system (GIS) was employed to show the spread of a particular known invasive plant species, Hedera helix within the area. Specimens were collected in …

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 …

Applying Wetland Rating Systems To Assess Functions Of Depressional Wetlands Created By A Mass Wasting Feature, Table Mountain, Washington, Thomas S. Wachholder

All Master's Theses

The formation of wetlands in the Swauk Watershed has been primarily controlled by mass wasting events, which includes landslide activity. Landslide activity has been the primary influential process in shaping the landscape where wetland systems have formed on the surface of landslide deposits. The wetland sites used in this study, near the base of Table Mountain, were chosen because they inhabit the same ancient landslide, have the same underlying geology, and vary in aspect and elevation. The elevational gradient of the sites ranges from 1300 – 1600 m and the individual wetlands differ in terms of north- and south-facing aspects. …

Proof-Of-Concept Of Environmental Dna Tools For Atlantic Sturgeon Management, Jameson Hinkle

Theses and Dissertations

Abstract

The Atlantic Sturgeon (Acipenser oxyrinchus oxyrinchus, Mitchell) is an anadromous species that spawns in tidal freshwater rivers from Canada to Florida. Overfishing, river sedimentation and alteration of the river bottom have decreased Atlantic Sturgeon populations, and NOAA lists the species as endangered. Ecologists sometimes find it difficult to locate individuals of a species that is rare, endangered or invasive. The need for methods less invasive that can create more resolution of cryptic species presence is necessary. Environmental DNA (eDNA) is a non-invasive means of detecting rare, endangered, or invasive species by isolating nuclear or mitochondrial DNA (mtDNA) from the …

Reforestation, Renewal, And The Cost Of Coal: Opposing A Manichean Worldview In Central Appalachia, Elizabeth R. Hansen

Pomona Senior Theses

Surface coal mining is a major form of land change and environmental degradation in Central Appalachia. Traditional mine reclamation iresults in unmanaged, unproductive grasslands that fail to mitigate many of the environmental costs of coal mining and are of minimal use to communities. Forestry reclamation is an alternative reclamation tactic that has the potential to address both environmental and socioeconomic concerns in Central Appalachia. A case study of Laurel Fork Mine in Eastern Kentucky is included.

Hydrologic And Temperature Regime Influence On Growth And Recruitment Of Fishes In An Upper Midwest Riverine Ecosystem, Brett Donald Nelson

All Graduate Theses, Dissertations, and Other Capstone Projects

The natural flow regime is often identified as the primary driver of ecological integrity in rivers. The Minnesota River basin is characterized by a row-crop agricultural landscape with an extensive network of drainage tiles and ditches to improve land productivity. Intensive surface and subsurface drainage alters flow regimes, increasing the magnitude and frequency of high flows. Changes in river hydrology lead to alterations in geomorphology, including increased bank erosion, channel widening, and downward incision that can lead to floodplain disconnection. Disruption of historical hydrology can alter energy flow and connection to specialized habitats subsequently affecting important aquatic communities and populations …

Small And Medium Enterprises' Profitability Elements In Green Energy Transactions, Humphrey Edereka Great

Walden Dissertations and Doctoral Studies

As the primary drivers of Nigeria's economy, small and medium scale enterprise (SME) leaders rely on standby generators for sustainable business operation. Because of this reliance, over 56% of the SMEs operate far below capacity from the effects of power shortages. Guided by the strategic contingency theory, this study explored the profitability strategies of business leaders faced with electricity disruptions within Abuja Federal Capital Territory while adopting corporate social responsibility (CSR) and green practices. Data collection was through face-to-face semistructured interviews using open-ended questions. Participants consisted of 12 business leaders selected from 4 SME categories within Abuja that have imbibed …
