Development And Assessment Of A Spatial Decision Support System For Conservation Planning, Sean Murphy Dec 2003

Development And Assessment Of A Spatial Decision Support System For Conservation Planning, Sean Murphy

Electronic Theses and Dissertations

Land conservation is frequently cited as the most effective means of limiting the detrimental effects of anthropogenic forces on natural resources. Because governmental entities can be hampered by fiscal and political concerns, land trusts are increasing relied on to protect habitat. However, these groups often lack the analysis and research tools necessary to meet their mission. Geographic Information System (GIs) technologies such as Spatial Decision Support Systems (SDSS) offer the promise of allowing decision makers to explore their decision space at a landscape level of analysis. But critics have charged that research in this arena is largely anecdotal in nature. …


Pond-Breeding Amphibian Species Distributions In A Beaver-Modified Landscape, Acadia National Park, Mount Desert Island, Maine, Jesse Cunningham Dec 2003

Pond-Breeding Amphibian Species Distributions In A Beaver-Modified Landscape, Acadia National Park, Mount Desert Island, Maine, Jesse Cunningham

Electronic Theses and Dissertations

In order to maintain pond-breeding amphibian species richness, it is important to understand how both natural and anthropogenic disturbances affect species assemblages and individual species distributions both at the scale of individual ponds and at a larger landscape scale. The goal of this project was to investigate what characteristics of ponds and the surrounding wetland landscape were most effective in predicting pond-breeding species richness and the individual occurrence of wood frog (Rana sylvatica), bullfrog (Rana catesbeiana) and pickerel frog (Rana palustris) breeding sites in a beaver-modified landscape and how this landscape has changed over …

Northwood School: The Survival Story Of An Educational Jewel In The Adirondacks, Perry Babcock

MALS Final Projects, 1995-2019

Northwood School is an example of a secondary boarding institution whose history mirrors the many changes in private education over the last one hundred years. As was the case with many of these private institutions, Northwood had to contend with the issue of isolation. The school's remote location caused it to evolve its own regional character. The school struggled financially as a not-for-profit institution that relied on tuition revenues and donations to maintain its stature in the competitive boarding school world. Northwood School also found itself challenged to sustain an educational philosophy when its market share dwindled and athletics became …

An Engineering, Economic, And Political Approach To Beach Erosion Mitigation And Harbor Development: A Review Of The Beach Communities Of Camp Ellis, Maine, Wells, Maine, And Cape May, New Jersey, Edmund Cervone

Electronic Theses and Dissertations

The history of coastal engineering projects is fraught with problems. In this thesis I examine the federal navigation project at Wells, Maine. In Wells, an incomplete understanding of the coastal setting led to a faulty engineering design responsible for a poorly functioning inlet and harbor and damage to neighboring beaches and wildlife habitat. Project planners and designers did not account for all unforeseen problems that arose. Reviewing the history of Wells Harbor demonstrates how proper attention to the natural setting, economics, and the political environment is essential to a successful project and enables agencies and stakeholders better to address contingencies …

The Conservation Reserve Management Access Program (CRP-MAP) is a joint effort of the Nebraska Game and Parks Commission and Pheasants Forever of Nebraska that seeks to address brood habitat needs of pheasants (Phasianus colchicus) and other grassland birds by light disking and interseeding legumes into portions of aging CRP fields. The program has two specific goals - increasing the total invertebrate availability as a food source for pheasant chicks and increasing the structural complexity of vegetation. This study compares invertebrate biomass and structural complexity of vegetation in treated (disked and interseeded with legumes) and idle portions of CRP-MAP fields to …


Assessment Of Potential Environmental Impacts Of Nature-Based Tours Originating Within Clark County, Nevada, Beth Domowicz Jan 2003

Assessment Of Potential Environmental Impacts Of Nature-Based Tours Originating Within Clark County, Nevada, Beth Domowicz

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this thesis was to assess the potential magnitude of negative environmental damage of nature-based tours originating in Clark County, Nevada. An ordinal ranking system was used for assessment of five variables. These variables were resource use, noise pollution, soil degradation, vegetation degradation, and wildlife disturbance. There were two proposed answers. The first was that as distance increased, negative tour impact would increase. This was not supported, since tours had high impacts for destinations that were close by and far away. The second was that most tours were not causing high damage to the environment. This hypothesis was …

Determination Of Home Techniques For Storing And Conserving Food In The Homes Of Cuambo And La Rinconada In Imbabura Province, 2001-2002, Marisol Caicedo Barrios

Theses and Dissertations

In Ecuador, there is a grave socioeconomic nutritional problem, and it is seen clearest in Imbabura province in the communities of Cuambo and La Rinconada. One of the biggest problems is inadequate food, due principally to the poor food storage and conservation habits. Considering this problem, it is necessary to deepen the knowledge of improved traditional techniques for storing and conserving food, through which families can store and manage their product better, controlling and avoiding losses due to insects, rodents, and climate, and guaranteeing conservation of the same. The investigation was oriented to implement alternative, improved storage and conservation technologies …
