Holistic Monitoring Of Maine Sea Lice (Lepeoptheirus Salmonis, Kroyer, 1837) Sensitivities To Therapies: Developing A Novel Assay To Examine Lice Behavior, Kathryn Liberman

Electronic Theses and Dissertations

Sea lice (Lepeoptheirus salmonis) present significant economic and animal welfare challenges to salmon aquaculture globally. Chemical delousing agents are used in many countries, with each nation eventually reporting sea lice developing reduced sensitivities to treatments. While some countries have in place sea lice sensitivity monitoring programs, that is not the case in Maine, USA. Although chemical delousing agents are not currently used in Maine, they have been used in the past and are currently used in neighboring Canadian salmon farms. Different bay management areas (BMAs) were sampled during different seasons to determine if there is a seasonal or spatial component …

Use Of Gis To Find Optimum Locations For Anaerobic Digestion Or Composting Facilities In Maine, Usha Humagain

Electronic Theses and Dissertations

As per US EPA, in 2017, 41 million tons of food waste was generated, but only 6.3% was diverted from landfills (US EPA, 2020). When landfilled or incinerated, organic waste (food waste, sludge, manure, agricultural waste) causes environmental pollution through greenhouse gas emissions, land, water, and air pollution. In contrast, if we compost or digest organic waste, we can generate soil additives and a mixture of methane and carbon dioxide gas to produce electricity or energy. Both digestion and composting reduce greenhouse gas emissions, improve the land through additives, and boost the economy. Many countries are adopting anaerobic digestion and …

Consumer Acceptability Of Gulf Of Maine Sugar Kelp Seaweed In Baked Bread, Laurel Simone

Electronic Theses and Dissertations

Although steady interest in edible seaweed cultivation continues to grow in Maine, research is lacking regarding consumer preferences and purchasing behavior of seaweed-containing products. The purpose of this study was to determine consumer acceptability of seaweed baked bread and provide insights into purchasing behavior to reveal potential consumer groups that are most likely to buy and eat baked products containing seaweed. Consumer preferences were determined by a sensory evaluation test and an online survey.

Sixty-five participants completed the central location test of freshly-baked bread containing seaweed. Participants were required to be at least 18 years of age, willing to eat …

Separating God's Two Kingdoms: Regular Baptists In Maine, Nova Scotia, And New Brunswick, 1780 To 1815, Ronald S. Baines

Electronic Theses and Dissertations

The trans-national Regular Baptist tradition in the northeastern borderlands of Maine, Nova Scotia, and New Brunswick grew rapidly from 1780 to 1815. The spiritual imperatives of this Calvinistic group with its commitment to believer’s baptism of adults and closed communion churches made them distinctive, and a central argument here is that the worldly implications of “Two Kingdom” theology, founded on the strict separation of religious and civil realms, was central to Regular Baptists’ success in the region in this period. Three leading ministers whose actions as authors, itinerants, and as organizational leaders receive especially close attention: Maine-based ministers Daniel Merrill …

Examining The Northern Shrimp Fishery In A Changing Gulf Of Maine, Ashley N. Charleson

Electronic Theses and Dissertations

Northern Shrimp (Pandalus borealis) once supported a key commercial fishery in the State of Maine. Since its closure in 2013, the stock has remained in a particularly vulnerable state following recruitment failure, overfishing, and rising water temperatures. Furthermore, without this source of supplemental income, local fishermen have also experienced financial stress following unstable fishing conditions in other fisheries. The collective goal of this research project was to assess factors impacting the feasibility of reopening and maintaining this vulnerable winter fishery. These goals are addressed over 4 chapters. Chapter two offers insight regarding what is most often omitted from the regulatory …

From The St. Croix To The Skutik: Expanding Our Understanding Of History, Research Engagement, And Places, Anthony Sutton

Electronic Theses and Dissertations

Situated in Maine rivers, I engage sites of memory present in places related to natural resources and research engagement. To address this, first I articulate an archeological analysis of Colonial American and early Maine history to describe land-based practices that shaped river ecology and interactions with Wabanaki people. This historical tension arises as the success of the timber industry required dams to transport lumber, blocking paths for migrating fish and restricting Wabanaki sustenance practices. Similarly, the process of resource extraction has continued in other forms placing Wabanaki people and First Nations more broadly, as the subjects of research through studying …

Snowmobiling In Maine: Economic Contributions And Registered Maine Guides, Ian Hathaway

Electronic Theses and Dissertations

Snowmobiling has been a popular winter pastime in Maine for decades. During the 2018-2019 snowmobiling season, nearly 85,000 snowmobiles were registered in Maine by both residents and non-resident snowmobile riders. While registrations show how many snowmobile owners are riding in Maine, an increasing part of the sport is now in rentals, which allows new or intermittent snowmobile riders to participate in the activity while avoiding the high price of modern machines. Another aspect of snowmobiling involves hiring Registered Maine Guides, by both renters and snowmobile owners, to lead tours. The Registered Maine Guide program standardizes the licensing procedure for all …

First-Year Computer Science Students: Pathways And Perceptions In Introductory Computer Science Courses, Christina A. Leblanc

Electronic Theses and Dissertations

This study examined student perceptions and experiences of an introductory Computer Science course at the University of Maine; COS 125: Introduction to Problem Solving Using Computer Programs. It also explored the pathways that students pursue after taking COS 125, depending on their success in the course, and their motivation to persist. Through characterizing student populations and their performance in their first semester in the Computer Science program, they can be placed into one of three categories that explain their path; a “continuer” (passed COS 125 and decided to stay in the major), a “persister” (did not pass COS 125 and …

Selling Eden: Economic Development And Conservation In Mount Desert Island And Acadia National Park, Christina Gail Arflack

Electronic Theses and Dissertations

This history of Mount Desert Island, Maine and Acadia National Park examines the issues and conflicts that arose as Mount Desert Island and the town of Bar Harbor grew from a quiet coastal village into a resort community. By tracing the developmental history of the island, this work places the creation of the national park within the context of decades of preceding development of the community as a tourist attraction. This region, now known for its beauty and the wealthy visitors it draws, hosted competing factions of local citizens and summer residents who often held disparate views regarding the islands …
