An Analysis Of Gulf Of Maine Cod Metapopulation Structure And Localized Stability, With Application To Area-Based Fisheries Management, Derek Olson
Electronic Theses and Dissertations
The complex metapopulation structure of groundfish stocks in the Gulf of Maine, particularly Atlantic cod (Gadus morhua), is largely ignored under the current system of broad-scale stock assessment and management. This mismatch of biological and administrative scales has contributed to severe overall stock decline and localized serial depletion of Gulf of Maine cod. Such chronic management failure has led to growing calls for a more area-based, finer-scale approach to managing groundfish in the Gulf of Maine. A primary difficulty hindering the development of finer-scale groundfish management has been the challenge of estimating fishing mortality upon local stock components. …
Measuring The Impact Of Pollution Closures On Commercial Shellfish Harvest: The Case Of Soft-Shell Clams In Machias Bay, Maine, Keith S. Evans, Kevin Athearn, Xuan Chen, Kathleen P. Bell, Tora Johnson
Measuring The Impact Of Pollution Closures On Commercial Shellfish Harvest: The Case Of Soft-Shell Clams In Machias Bay, Maine, Keith S. Evans, Kevin Athearn, Xuan Chen, Kathleen P. Bell, Tora Johnson

Temporary closures of polluted coastal waters to shellfish harvesting protect human health but also generate broad socioeconomic impacts on rural, fishing-dependent communities. Improved understanding of these impacts could help coastal managers prioritize investments to protect water quality and mitigate the effects of coastal pollution. Using a regression model of monthly landings, we explore the impact of temporary closures on the commercial harvest of soft-shell clams (Mya arenaria) in the Machias Bay region of Maine (USA). We find that economic losses are significant and depend heavily on tidal activity, and the size, frequency and timing of closures. Over the …
Social Ecological Food Systems: Sustainability Lessons From Maine Dairy Networks, Julia B. Mcguire
Social Ecological Food Systems: Sustainability Lessons From Maine Dairy Networks, Julia B. Mcguire
Electronic Theses and Dissertations
Milk production has played an integral role in the culture, landscape, and economy of Maine’s agriculture. Maine dairy farmers have faced numerous sustainability challenges to economic, environmental, and social aspects of their industry. Like many other complex social ecological systems, the Maine dairy industry faces a gap between scientific knowledge and actionable management or policy. A cultural dichotomy exists between conventional and organic farming. Shifting the focus from this binary, metrics such as social capital may play a key role in solving sustainability issues. Difficulties arise in the governance of complex social ecological systems when the scales of assessment, management, …
Marine Sciences At The University Of Maine, 1960-2015, Catherine Schmitt, Shelby Hartin
Marine Sciences At The University Of Maine, 1960-2015, Catherine Schmitt, Shelby Hartin
Maine History
The development of marine science research, teaching, and service at the University of Maine formally began in 1965, when Ira Darling and Clare Shane Darling transferred their 127-acre farm and woodlot on the Damariscotta River in South Bristol to the University. Their express purpose was to establish a marine laboratory. The gift fulfilled the decades old desire by University of Maine scientists and administrators to do just that. UMaine quickly began hiring faculty, starting research projects, building structures, developing courses, and creating ties to state and federal agencies. The transition from farm to world-class facility and laboratory was gradual, with …
Moving Up The Waste Hierarchy In Maine: Learning From “Best Practice” State-Level Policy For Waste Reduction And Recovery, Cindy Isenhour, Travis Blackmer, Travis Wagner, Linda Silka, John Peckenham

As Maine residents look toward the future, it is increasingly clear that more sustainable waste and materials management solutions will be necessary. A recent stakeholder engagement process involving nearly 200 industry professionals, municipal representatives and citizen groups confirmed this point. As we move together toward a more sustainable waste management system, participants in the engagement process identified an outstanding need to learn more about policies options. This article responds to that need with a review of state level policies designed to reduce waste generation and increase material recovery rates. We find there are a wide variety of state-level policy tools …
