Sea Level Rise Impacts And The Value Of Affected Properties In Barnstable, Ma, Matthew Lapine

Atlas of Maine

A recent study by the nonprofit organization Climate Central found that over 3.7 million Americans live within 1 meter of the high tide mark along coastlines (Strauss, et al., 2012). The same study warned of the implications of rising sea levels, and how the increase predicted by the International Panel on Climate Change (IPCC) could have drastic effects on many Americans. This projected aimed to model the range of potential sea level rise from the best to worst case scenario (0-6 meters) (IPCC, 2007).

This project aimed to determine if higher value properties along the coast are disproportionally affected by …

Watersheds On The Brink: Impervious Surface Cover In Casco Bay, Me, Elizabeth Schneider, Michael Whalen

Atlas of Maine

Casco Bay and its surrounding watersheds are threatened by increased impervious coverage in urban areas. We used ArcGIS to assign values for percent coverage by impervious surfaces to all watersheds at the HUC 12 level for the Casco Bay region in order to determine which would most benefit from management and restoration. To further pinpoint watersheds at the intermediate level of disturbance, we factored in riparian buffers of 20m around all streams and calculated percent coverage by impervious surfaces within these zones. Total impervious coverage within subwatersheds ranged from 0 to 26% with a mean of 5.7%, while cumulative impervious …

Suitable Land Cover Habitats For Elephant And Cheetah Populations, Ellie Linden

Atlas of Maine

Human influence has caused cheetah and elephant populations to become endangered, resulting in an essential demand to help conserve these African species. Scientific research has suggested that elephants favor savanna woodland and sand forest vegetation, and adjust their movement in order to avoid human interactions or unexplored areas (Druce, 2008). Elephants are threatened by habitat loss, hunting by farmers, and overexploitation through the ivory trade (Bagheera, 2012). Elephants are keystone species in their ecosystems, making them important targets for conservation efforts. Cheetahs are threatened by habitat loss, hunting by farmers, and prey decline (CCF, 2012). Cheetahs are predators in their …

Effects Of Visitation On Reid State Park In Georgetown, Me, Meagan Hennessey

Atlas of Maine

Maine State Parks are in their 77th year, providing public access to a variety of scenic views, picnicking opportunities, freshwater and saltwater swimming, hiking, camping and a variety of other activities.1 These opportunities allow individuals to experience relatively undeveloped nature and can protect habitat for a variety of wildlife. On the other hand, concentrating large amounts of people in these natural areas can lead to degradation, and should be monitored closely and managed to the greatest ability.

In 2010, Reid State Park, in Georgetown, Maine was the most visited Maine State Park for day use, with 181,149 visitors.2 The Park …

Atlas Of Maine: Essential Seabird Habitats Of The Gulf Of Maine, Michael Whalen

Atlas of Maine

This map relates seabird nesting habitats with the biophysical regions of coastal Maine. Layers were downloaded from the Maine office of GIS.

Seabird Nesting Islands host myriad species including Great Black-backed Gulls, Herring Gulls, Laughing Gulls, Black Guillemots, Razorbills, Atlantic Puffins, Common Terns, Arctic Terns and the critically endangered Roseate Tern. Also represented are overlapping critical habitats for Least Terns and Piping Plovers, the former of which is endangered in the state of Maine. Note that Habitat representations are enlarged for …

Distribution Of Atlantic Forest Fragments In Relation To Probable Water Sources, Dominique Kone, Lydia Ball

Atlas of Maine

The Atlantic Forest of Brazil is highly fragmented and it is estimated that less than 7% of its original area remains (Umetsu et al. 2008). This high rate of fragmentation is primarily due to the conversion of forested areas into agricultural lands. This may hinder the dispersal of many species that inhabit this area because of an increase in edge effects, decrease in reproductive success, and higher limitation of resources. However, the inter-habitat matrix, or heterogeneous mosaic of varying habitats, may allow population dispersal and the creation of meta-populations within species. In particular, amphibians are extremely sensitive to habitat degradation …

Atlas Of Maine: Surficial Materials, Katherine Murray

Atlas of Maine

This map was created using surficial geology data, Maine lakes and rivers data, and state hillshade data from the Maine Office of GIS. This map specifically focuses on the surficial materials of Maine geology. Surficial material refers to the types of sediment that are deposited onto the bedrock from glaciers. Surficial materials maps are important for a variety of reasons including: construction planning, locating sand and gravel pits, locating suitable landfills etc.

A Postulate For Tiger Recovery: The Case Of The Caspian Tiger, Carlos A. Driscoll, I Chestin, H Jungius, Y Darman, E Dinerstein, J Seidensticker, J Sanderson, S Christie, S J. Luo, M Shrestha, Y Zhuravlev, O Uphyrkina, Y V. Jhala, S P. Yadav, D G. Pikunov, N Yamaguchi, D E. Wildt, J D. Smith, Marker, Philip J. Nyhus, R Tilson, D W. Macdonald, S J. O'Brien

Faculty Scholarship

Recent genetic analysis has shown that the extinct Caspian Tiger (P. t. virgata) and the living Amur Tigers (P. t. altaica) of the Russian Far East are actually taxonomically synonymous and that Caspian and Amur groups historically formed a single population, only becoming separated within the last 200 years by human agency. A major conservation implication of this finding is that tigers of Amur stock might be reintroduced, not only back into the Koreas and China as is now proposed, but also through vast areas of Central Asia where the Caspian tiger once lived. However, under the current tiger conservation …

Cameras, Satellites, And Surveys: A Multi-Platform Approach To Monitoring Lake Conservation Behavior, Daniel D. Homeier

Honors Theses

Shoreline buffers are essential to maintaining lake water quality and there are numerous methods for their assessment. There is uncertainty in the benefits and drawbacks of different shoreline buffer assessment methods. In this study I explore three methods of remotely assessing shoreline buffers in the Belgrade Lakes Region of Maine: household surveys, geotagged shoreline photos, and satellite imagery. By comparing these three methods I will evaluate their accuracy and applicable scale when used to assess the presence and quality of shoreline buffers.

I used both parametric and non-parametric analysis to (1) evaluate the relative accuracy of 154 household surveys in …

From Pond To Pump: Microalgae As A Feedstock For Biodiesel, Anna H. Leavitt

Honors Theses

The global reliance on fossil fuels is an unsustainable practice that has led to the depletion of finite resources and the accumulation of greenhouse gases in the atmosphere, leading to global climate change (Demirbas 2010). Transportation accounts for about a third of carbon dioxide (CO2) emissions in the United States. Demand for oil continues to increase and resources are becoming more uncertain. Increased production of renewable fuels such as biofuels can help ease the dependence on fossil fuels. Although interest and production in biofuels has been increasing in the past decade, current feedstocks do not meet efficiency needs and some …
