The Effects Of Sediment Acidification And Temperature On The Immune Capacity Of The Atlantic Jackknife (Razor) Clam (Ensis Leei M. Huber, 2015), Brian Preziosi
The Effects Of Sediment Acidification And Temperature On The Immune Capacity Of The Atlantic Jackknife (Razor) Clam (Ensis Leei M. Huber, 2015), Brian Preziosi
Electronic Theses and Dissertations
Sediment acidification has been shown to negatively impact clams of economic importance such as the soft-shell clam, Mya arenaria Linnaeus, 1758, and hard clam, Mercenaria mercenaria (Linnaeus, 1758). Effects of sediment acidification on razor clams, including the Atlantic jackknife clam Ensis leei M. Huber, 2015, are unknown. E. leei has been identified as a species with potential for aquaculture operations on the New England coast. E. leei may be resilient to acidification and thus persist in acidified sediments where other clams cannot. To this end, the impact of acidified surface sediment on the internal immune capacity of adult (mean shell …
Fish Passage And Hydropower: Investigating Resource Agency Decision-Making During The Ferc Hydropower Relicensing Process, Sarah Vogel
Electronic Theses and Dissertations
Hydropower dams represent a significant challenge for the successful migration of sea-run fish, many species of which are in decline. Most hydropower dams in the United States are regulated by the Federal Energy Regulatory Commission (FERC), an independent federal agency responsible for granting 30 to 50-year licenses to projects for their continued operation. Licenses typically include conditions for the conservation of sea-run fish such as fish passage construction, operational changes, monitoring of effectiveness, and other mitigative conditions. While FERC remains the primary authority in licensing, the current regulatory framework stipulates input from other federal and state resource and regulatory agencies, …

Getting Over The Dam: Overcoming Institutional Barriers To The Recovery Of Atlantic Salmon By Navigating The Social-Science/Policy Interface, Melissa E. Flye
Electronic Theses and Dissertations
The term governance has undergone somewhat of an evolution since its inception, originally describing the act of governing, it has come to represent a more collaborative form of governing which is distinct from hierarchical control models (Marin and Mayntz, 1991). Collaborative governance refers to the systems associated with public policy decision making and resource management which span the jurisdictional boundaries of public agencies, levels of government, and/or public and private spheres in order to pursue a public policy goal or outcome (Emerson et al., 2012). Environmental management is often considered an inherently collaborative effort, as ecological systems and species rarely …
Assessing Migrations And Habitat Connectivity For Two Anadromous Species Following A Major Restoration Effort In The Penobscot River, Maine, George A. Maynard
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 …
Examining Citizens' Preferences For Aquaculture Using Discrete Choice Experiments, Olga Bredikhina
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. …
