Sharing A Landscape: The Construction Of Sense Of Place On The Maine Coast, Andrea Jane Ednie
Sharing A Landscape: The Construction Of Sense Of Place On The Maine Coast, Andrea Jane Ednie
Electronic Theses and Dissertations
Motivated by interest and concern over the changing coastline in Maine, this study uses the concept of sense of place to develop an understanding of how a range of users share the resource, and to explore how place meanings are associated with their social experiences and perceptions. The site for this study was the Stonington region archipelago, an area that has not yet experienced the same amount of development as seen on the southern Maine coast, yet one that has witnessed a boom in recreational use and an influx of people from other areas. Using a mixed methodology, two groups …
Risk Assessment For Hazardous Materials Incident, Washington County, Tennessee: Road Transportation, Rail Transportation, And Hazardous Materials Storage., Steed Kenlee Stagnolia
Risk Assessment For Hazardous Materials Incident, Washington County, Tennessee: Road Transportation, Rail Transportation, And Hazardous Materials Storage., Steed Kenlee Stagnolia
Electronic Theses and Dissertations
This study was conducted to provide a quantitative risk assessment for road transportation, railway transportation, and storage of hazardous materials in Washington County, Tennessee. A roadside survey, railroad hazardous materials survey, and a chemical inventory were conducted. It revealed an estimated 267,858 HAZMAT shipments per year on primary and secondary roadways and an estimated total of 9.4 x 109 tons of HAZMAT shipped by rail per year. There are 49 facilities that store a daily average of 33,722,700 lbs of HAZMAT. The risk of a hazardous materials incident occurring in Washington County is highest for Interstate transportation. The risk for …
Economic Approaches To Public And Private Land Conservation In The United States, Amy Claire Hudnor
Economic Approaches To Public And Private Land Conservation In The United States, Amy Claire Hudnor
Electronic Theses and Dissertations
This research is composed of two essays, both using economic approaches to evaluate land conservation in the United States. Essay I uses econometric methods to evaluate public lands, and Essay II uses New Institutional Economics to gain insight into private land conservation. Essay I is titled "The Relationship Between Public Conservation Lands and Tourism Employment in the United States." This research examines the relationship between public conservation lands and the importance of tourism in United States counties. A spatial error model is used on three categories of conservation land: general public land, recreational land, and wilderness areas. A positive, significant …
Myriophyllum Heterophyllum Michx. (Haloragaceae): Control And Vegetative Reproduction In Southwestern Maine, Jacolyn E. Bailey
Myriophyllum Heterophyllum Michx. (Haloragaceae): Control And Vegetative Reproduction In Southwestern Maine, Jacolyn E. Bailey
Electronic Theses and Dissertations
Native to the southeastern United States, variable-leaf watermilfoil (Myriophyllum heterophyllum) is an invasive species in the Northeast and has been documented in Maine lakes for twenty years. Variable-leaf watermilfoil is targeted by the Maine Department of Environmental Protection as a species of grave concern as it has aggressively colonized twenty-six water bodies in Maine. This aquatic invasive plant grows in dense mats and outcompetes native vegetation. It is causing both ecological and economic disruption to Maine's lakes and ponds. The plants clog boat motors and deter people from swimming and other water related activities. Allofragmentation and autofragmentation occur …
Early Life Stage Characteristics Of Six Acadian Conifer Species: Germination And Seedling Development In A Changing Climate, Jason D. Schatz
Early Life Stage Characteristics Of Six Acadian Conifer Species: Germination And Seedling Development In A Changing Climate, Jason D. Schatz
Electronic Theses and Dissertations
Global climate change will drastically alter regional climates. The influence of these changes on the distribution and relative abundance of forest trees is both critically important and subject to substantial uncertainty. It will be particularly important to understand the effects of different climate scenarios on the early life stages of major tree species, because: 1) Early life stage performance and survival strongly influence the abundance of mature trees of a given species, 2) Trees are most sensitive to environmental variation during their early life stages, and 3) Our knowledge of the response of Acadian Forest tree species to environmental variation …
Methods For The Translocation Of The Yellow Lampmussel (Lampsilis Cariosa) And The Tidewater Mucket (Leptodea Ochracea) In The Fort Halifax Dam Impoundment Of The Sebasticok River, Maine, Jennifer Elaine Kurth
Methods For The Translocation Of The Yellow Lampmussel (Lampsilis Cariosa) And The Tidewater Mucket (Leptodea Ochracea) In The Fort Halifax Dam Impoundment Of The Sebasticok River, Maine, Jennifer Elaine Kurth
Electronic Theses and Dissertations
Translocation from areas where habitat alterations are proposed can be an important mussel conservation tool. Pending removal of the Fort Halifax dam on the Sebasticook River in Maine potentially would result in extensive mortality of two statelisted threatened species of mussels, yellow lampmussels (Lampsilis cariosa) and tidewater muckets (Leptodea ochracea), which occur in the impoundment above the dam. My study assessed populations of these two species in the impoundment, and determined the effects of within- and between-waterbody translocations on survival. I conducted a qualitative survey of the Fort Halifax dam impoundment in 2004 to determine locations …
Effect Of Coyotes And Release Site Selection On Survival And Movement Of Translocated Swift Foxes In The Badlands Ecosystem Of South Dakota, Greg M. Schroeder
Effect Of Coyotes And Release Site Selection On Survival And Movement Of Translocated Swift Foxes In The Badlands Ecosystem Of South Dakota, Greg M. Schroeder
Electronic Theses and Dissertations
Success of different release strategies for swift fox (Vulpes velox) translocation was evaluated in the Badlands Ecosystem in southwestern South Dakota. Release site selection (outside coyote [Canis latrans] core-use areas compared to random release sites) and release method (i.e., hard, semi-hard, and soft) were examined to determine effects on swift fox survival and movements at 50 days post-release. I hypothesized that swift foxes released outside of coyote core-use areas would survive at a higher rate than foxes released at random sites. From 2003-2006, 16 adult coyotes were fitted with Global Positioning System (GPS) radio collars and monitored during the pup …
