Recruitment Facilitation And Spatial Pattern Formation In Soft-Bottom Mussel Beds, John A. Commito, Ann E. Commito, Rutherford V. Platt, Benjamin M. Grupe, Wendy Dow Piniak, Natasha J. Gownaris, Kyle A. Reeves, Allison M. Vissichelli

Environmental Studies Faculty Publications

Mussels (Mytilus edulis) build massive, spatially complex, biogenic structures that alter the biotic and abiotic environment and provide a variety of ecosystem services. Unlike rocky shores, where mussels can attach to the primary substrate, soft sediments are unsuitable for mussel attachment. We used a simple lattice model, field sampling, and field and laboratory experiments to examine facilitation of recruitment (i.e., preferential larval, juvenile, and adult attachment to mussel biogenic structure) and its role in the development of power-law spatial patterns observed in Maine, USA, soft-bottom mussel beds. The model demonstrated that recruitment facilitation produces power-law spatial structure similar …

Alewives are sea-run, or diadromous, fish that spend most of their lives in the Atlantic Ocean but return as adults to coastal rivers in spring to spawn in freshwater streams and ponds. This article in Maine Boats, Homes, & Harbors magazine discusses the natural and cultural history of Maine's native runs of alewives and other sea-run fish.


Reaching Into The Past For Future Resilience: Recovery Efforts In Maine Rivers And Coastal Waters, John Lichter, Ted Ames Jan 2012

Reaching Into The Past For Future Resilience: Recovery Efforts In Maine Rivers And Coastal Waters, John Lichter, Ted Ames

Maine Policy Review

John Lichter and Ted Ames discuss how analysis of environmental histories of human activities affecting Maine’s estuary, river, and coastal marine ecosystems can shed light on the role key fish species may play. Through Maine’s Sustainability Solutions Initiative, a group of researchers from Bowdoin, Bates, Univer­sity of Southern Maine, and Penobscot East Resource Center have teamed up to examine ecological recovery in the state’s waterways and coastal fisheries. Several river restoration efforts were already underway, and others are being planned as a direct result of this inter­disciplinary project.


Building A Sustainable Seafood System For Maine, Robin Alden Jan 2011

Building A Sustainable Seafood System For Maine, Robin Alden

Maine Policy Review

In this article, Robin Alden notes that Maine could have one of the premier marine food systems in the world. However, that means adequate steward­ship of the Gulf of Maine ecosystem and diversifying the fishing industry beyond lobster by creating innovative public policy and a food system that supports community fishing.

Effects Of Fish Introductions On The Geographic Distribution And Native Invertebrate Biodiversity Of Naturally Fishless Lakes In Maine, Emily Gaenzle Schilling Aug 2008

Effects Of Fish Introductions On The Geographic Distribution And Native Invertebrate Biodiversity Of Naturally Fishless Lakes In Maine, Emily Gaenzle Schilling

Electronic Theses and Dissertations

Widespread fish stocking has led to a worldwide decline in naturally fishless lakes and their associated communities. Little is known about the historical distribution or native communities of these freshwater ecosystems. The objectives of this study were to: 1) develop a quantitative method to remotely detect naturally fishless lakes in Maine, 2) conduct a landscape-scale assessment of unique attributes of fishless lake macroinvertebrate communities, 3) identify macroinvertebrate bioindicators of fish absence, and 4) assess effects of introduced fish on native macroinvertebrates. I identified two physiographic types of naturally fishless lakes in Maine: kettle lakes in the eastern lowlands and foothills …


Changing Maine, 1960-2010: Teaching Guide, Richard Barringer, New England Environmental Finance Center Jul 2006

Changing Maine, 1960-2010: Teaching Guide, Richard Barringer, New England Environmental Finance Center

Maine History & Policy Development

Unlike forty years ago, none of us is now certain what the future holds for Maine – except that it will be different. Maine has been transformed by the events of the recent decades. We have come into a new world, a new time – a new historical era, if you will. This new era, like previous eras in Maine history, will require of us new ways of thinking, new ways of understanding, new ways of organizing ourselves as a community of people, if the values and culture we share and cherish are to endure and flourish.


Population Dynamics And Spatial Analysis Of The Maine Green Sea Urchin (Strongylocentrotus Droebachiensis) Fishery, Robert C. Grabowski May 2003

Population Dynamics And Spatial Analysis Of The Maine Green Sea Urchin (Strongylocentrotus Droebachiensis) Fishery, Robert C. Grabowski

Electronic Theses and Dissertations

Fisheries research on the green sea urchin in Maine has been limited despite its importance to the state's fishing industry. The objective of this thesis was to generate critical information for the management and monitoring of the Maine green sea urchin fishery. In particular there are three main areas of interest: (1) an investigation of biological reference points; (2) spatial analysis and biomass estimation, and (3) the development of a simulation framework approach to determine an optimal sampling strategy for the fishery-independent survey program. Biological reference points are markers conlrnonly used to monitor and manage fisheries. For the Maine sea …


Evolution Of The Maine Lobster Co-Management Law, James Acheson, Terry Stockwell, James A. Wilson Jan 2000

Evolution Of The Maine Lobster Co-Management Law, James Acheson, Terry Stockwell, James A. Wilson

Maine Policy Review

In fisheries management circles, there is growing realization that traditional ways of managing marine resources are not working and that new approaches to management need to be tried. One of the most promising of these new approaches is co-management, where authority for managing fish stocks is shared between the industry and government agencies. This paper discusses the implementation of the new co-management system, which was initiated in the Maine lobster industry in 1995. The law has clearly been successful; it has been framed in a way to allow lobster fishermen to be able to generate rules to constrain their own …


Developing A Cooperative Research Agenda For Maine’S Commercial Fisheries, Robin Alden, Linda Mercer Jan 2000

Developing A Cooperative Research Agenda For Maine’S Commercial Fisheries, Robin Alden, Linda Mercer

Maine Policy Review

This past year the Maine Department of Marine Resources sponsored a unique series of meetings involving fishermen, academic and government scientists, and fishery managers. The goal was to define a shared research agenda for Maine’s marine fisheries. Robin Alden and Linda Mercer summarize the results of these meetings. In doing so they address the question: “What do we need to know to properly manage Maine's major marine resources?” Alden and Mercer also conclude that the collaborative process these meetings helped to establish is one of the keys to the successful management of Maine’s marine resources.


Best Practices In Endangered Species Recovery Planning: Lessons For The Conservation Of Maine’S Atlantic Salmon, Raymond J. O’Connor, Ray B. Owen, Judith Rhymer Jan 2000

Best Practices In Endangered Species Recovery Planning: Lessons For The Conservation Of Maine’S Atlantic Salmon, Raymond J. O’Connor, Ray B. Owen, Judith Rhymer

Maine Policy Review

The call for federal listing of Atlantic salmon as endangered implies that such action will result in a recovery plan for the species that is superior to Maine ’s Atlantic Salmon Conservation Plan. In this article the authors compare the Maine plan against the findings of a recent review of Endangered Species Act recovery plans. The review, conducted by the Society for Conservation Biology in collaboration with the U.S. Fish and Wildlife Service, assessed the quality of a national sample of Endangered Species Act recovery plans with the intention of identifying “best practice.” By comparing the Maine plan to the …

Dickey-Lincoln School Lakes Project

This introduction of the St. John River watershed is situated in a transitional zone between the Boreal Forest Formation and the Eastern Deciduous Forest Formation. Second-growth forests representative of these two ecosystems cover extensive areas of the project site. The boreal forest forms a broad transcontinental belt in northern North America and Eurasia, with southern montane extensions. This northern forest is characterized by evergreen, coniferous trees, predominately spruce-fir The eastern deciduous forest, composed of broad-leaved hardwoods, extends throughout the eastern United States except Florida (Dasmann, 1968; Oosting, 1956).
