Assessing The Long-Term Effects Of Natural Disturbance-Based Silvicultural On The Avian Assemblage At The Acadian Forest Ecosystem Research Program, Carl Pohlman
Electronic Theses and Dissertations
Active forest management alters the resources available to forest-obligate species. Large-scale intensive management practices where timber production is the primary objective can lead to notable ecological changes in forest ecosystems. A key concept of ecological forestry is to design forest management activities to emulate natural disturbance regimes as a way to maintain the ecological integrity of forests. The Acadian Forest Ecosystem Research Program (AFERP) was undertaken as an experimental demonstration of management reflective of the region’s disturbance regime, which typically produces small canopy gaps. AFERP includes nine research areas assigned to three silvicultural treatments: unharvested control, small gap (expanding-group selection …
Anthropogenic Impacts To Essential Habitats In The Gulf Of Maine: A Case Study Of The American Lobster, Homarus Americanus, And Its Fishery, Andrew Goode
Electronic Theses and Dissertations
The Gulf of Maine has been fundamentally altered by anthropogenic forcings for decades and offers an ideal study system to monitor response to change. Through complex interactions between ocean warming, altered demographic bottlenecks, and reduced top-down controls, the American lobster (Homarus americanus Milne Edwards) capitalized on favorable conditions and proliferated within the Gulf of Maine. These changes catalyzed the expansion of the lobster fishery, elevated its status as North America’s most valuable marine resource, and shifted coastal communities towards a virtual lobster monoculture. The same processes that facilitated lobster to capitalize on favorable conditions may come with unintended consequences …

Detrital Protein Contributes To Oyster Nutrition And Growth In The Damariscotta Estuary, Maine, Usa, Cheyenne M. Adams
Detrital Protein Contributes To Oyster Nutrition And Growth In The Damariscotta Estuary, Maine, Usa, Cheyenne M. Adams
Electronic Theses and Dissertations
Oyster aquaculture is an expanding industry that relies on identifying and utilizing natural estuarine conditions for the economically viable production of a filter-feeding crop. The eastern oyster, Crassostrea virginica, is the principal species currently cultured in Maine. In addition to preferentially consumed phytoplankton, various detrital complexes (non-algal and/or non-living organic matter) may provide some nutrition to C. virginica between times of phytoplankton abundance. Here I investigated the importance of detrital proteins in supporting the growth of oysters cultured in the upper Damariscotta Estuary. Oyster aquaculture in this area is highly successful and previous reports indicate that labile detrital protein …
Evaluating Potential For Water Quality Decline In Maine Lakes, Kaci N. Fitzgibbon
Evaluating Potential For Water Quality Decline In Maine Lakes, Kaci N. Fitzgibbon
Electronic Theses and Dissertations
Understanding lake vulnerability with respect to eutrophication and loss of water quality is important for sustainability of aquatic ecosystems. This project aims at identifying and quantifying the effects of relevant physiochemical, climate, and watershed characteristics on lake vulnerability in order to develop management decision tools for the Maine Department of Environmental Protection (MEDEP). In a changing chemical and physical environment, using independent variables from each of these categories and then relating them to the summer lake epilimnetic phosphorus (P) concentrations allows for development of models to inform stakeholders of lake vulnerability to eutrophication problems.
We studied 24 lakes covering a …
Evaluation Of A Waistband For Attaching External Radiotransmitters To Anurans, Luke Alexander Groff, Amber Pitt, Robert Baldwin, Aram J K Calhoun, Cynthia Loftin
Evaluation Of A Waistband For Attaching External Radiotransmitters To Anurans, Luke Alexander Groff, Amber Pitt, Robert Baldwin, Aram J K Calhoun, Cynthia Loftin
Publications
Radiotelemetry provides fine-scale temporal and spatial information about an individual's movements and habitat use; however, its use for monitoring amphibians has been restricted by transmitter mass and lack of suitable attachment techniques. We describe a novel waistband for attaching external radiotransmitters to anurans and evaluate the percentages of resulting abrasions, lacerations, and shed transmitters. We used radiotelemetry to monitor movements and habitat use of wood frogs (Lithobates sylvaticus) in 2006 and 2011–2013 in Maine, USA; American toads (Anaxyrus americanus) in 2012 in North Carolina, USA; and, wood frogs, southern leopard frogs (L. sphenocephalus), and green frogs (L. clamitans) in 2012 …
The Path To Sustainable Water Resources Solutions, John Peckenham, David Hart, Sean Smith, Shaleen Jain, Whitney King
The Path To Sustainable Water Resources Solutions, John Peckenham, David Hart, Sean Smith, Shaleen Jain, Whitney King
Maine Policy Review
Water is essential both to human survival and to the ecosystems on which people depend. Although Maine is blessed with abundant water sources, managing them is crucial for both short and long-term uses. The authors describe the varying time and spatial scales involved in managing water resources, pointing out that policy decisions made at one time can have far-reaching consequences. They provide illustrations of water-resource projects from Maine’s Sustainability Solutions Initiative, ranging in size from Sebago Laketo vernal pools on individual properties.
