Examining Citizens' Preferences For Aquaculture Using Discrete Choice Experiments, Olga Bredikhina May 2019

Examining Citizens' Preferences For Aquaculture Using Discrete Choice Experiments, Olga Bredikhina

Electronic Theses and Dissertations

Over the last few decades, discrete choice experiments (DCEs) have become increasingly popular across different subfields of economics as a way to elicit citizens‟ stated preferences for product and service attributes as well as various environmental and infrastructure features. The DCE framework could be seen as a time- and cost-effective alternative to the revealed preferences framework that is based on data obtained using transactions observed in real-world markets. DCEs offer the advantage over revealed preferences data because they allow learning about consumer preferences for hypothetical products or product attributes without bearing the costs of introducing new products to the market ...


Assessing Migrations And Habitat Connectivity For Two Anadromous Species Following A Major Restoration Effort In The Penobscot River, Maine, George A. Maynard May 2019

Assessing Migrations And Habitat Connectivity For Two Anadromous Species Following A Major Restoration Effort In The Penobscot River, Maine, George A. Maynard

Electronic Theses and Dissertations

The construction of industrial dams across major rivers in New England began in the early 1800s with textile mills in Massachusetts. Because of its legacy of mill dams and log driving dams, New England has the highest density of dams anywhere in North America, averaging one dam for every 44 km2 of drainage area. By the early 1900s, these dams drastically limited migrations by diadromous fishes, resulting in declines in populations of migratory fishes, including Atlantic salmon Salmo salar and American shad Alosa sapidissima. Since that time, different fishway designs and river management plans have been tried around the ...


Overwinter Survival Rate Of Moose (Alces Alces) Calves In Relation To Habitat Composition, Bridget Re Apr 2019

Overwinter Survival Rate Of Moose (Alces Alces) Calves In Relation To Habitat Composition, Bridget Re

Honors College

Naturally occurring resource scarcity and limited foraging in winter habitats of northern New England moose (Alces alces) calves result in an energetic strain—particularly for individuals experiencing winter tick (Dermacentor albipictus) parasitism. Recent collaborative studies conducted between Maine’s Department of Inland Fisheries and Wildlife (MIFW) and the University of New Hampshire have attributed the decline of winter survival in moose (Alces alces) calves to be closely linked to winter tick (Dermacentor albipictus) parasitism (Jones et al 2018, Ellingwood et al. 2018, Healy et al. 2018, Pekins 2018). In addition to winter tick abundance on individuals, we analyzed how winter ...


Landscape Factors Affecting Foraging Flight Altitudes Of Great Blue Heron In Maine; Relevance To Wind Energy Development, Lauren Dolinski Apr 2019

Landscape Factors Affecting Foraging Flight Altitudes Of Great Blue Heron In Maine; Relevance To Wind Energy Development, Lauren Dolinski

Honors College

In an attempt to increase alternative energy sources, there has been greater development of wind farms across the United States. This expanded development may pose a potential threat to birds that are flying overhead (EIA 2017, Leung and Yang 2011). More information is needed on the factors that affect a bird’s behavior while flying and if the current policies and dimensions of wind turbines interfere with flight altitudes. We used data from GPS-marked great blue herons (Ardea herodias) in Maine to classify their flight altitudes relative to wind turbine height and assess different landscape factors that affect flight altitude ...


A History Of Oysters In Maine (1600s-1970s), Randy Lackovic Mar 2019

A History Of Oysters In Maine (1600s-1970s), Randy Lackovic

Darling Marine Center Historical Documents

This is a history of oyster abundance in Maine, and the subsequent decline of oyster abundance. It is a history of oystering, oyster fisheries, and oyster commerce in Maine. It is a history of the transplanting of oysters to Maine, and experiments with oysters in Maine, and of oyster culture in Maine. This history takes place from the 1600s to the 1970s.
