Collaborative And Engaged Research To Strengthen Equity And Adaptive Governance In Co-Managed Fisheries, Gabrielle V. Hillyer

Electronic Theses and Dissertations

Small-scale, co-managed fisheries are found throughout the world and often represent intertwining cultures, societies, communities, economies, institutions, and governments. They face complex issues, derived from ecological and social sources. Solving these issues requires diverse expertise, often developed through engaged methodologies which can facilitate collaborative solution creation between researchers, community members, and others. In this dissertation, I demonstrate the benefits of these engaged methodologies and review how they, when coupled with anticolonial approaches to research, can create more equitable solutions to complex issues. This dissertation focuses on multiple projects within the wild clam fishery in Maine including: (1) the creation of …

An Exploration Of Palauan Fishing Methods And Fisheries: A Study For The Conservation Of Dugongs, Mia Glover

Electronic Theses and Dissertations

The dugong (Dugong dugon) is an important marine mammal in Palau. However, current population dynamics are not well understood. This study aimed to connect scientific data with local knowledge by examining the social implications of changing fishing methods and their impact on dugong population dynamics in the face of climate change and fisheries commercialization. Through interviews with local fishers, it was found that destructive fishing methods like trawling and long lining have led to habitat loss and degradation for dugongs. These tactics, driven by economic factors, have disrupted the delicate balance between human activities and the preservation of dugong habitats, …

Seabirds As Proxies For Past El Niño Events In Coastal Peru: An Archaeo-Ornithological Approach, Heather A. Landazuri

Electronic Theses and Dissertations

This thesis sets an initial foundation for an archaeo-ornithological approach to understanding past El Niño events on the coast of Peru and the use of avifaunal remains as proxies for ecological conditions. Although faunal remains from archaeological sites do not provide exact representations of past environmental conditions, and bird remains can be especially challenging environmental indicators, their presence does reflect decisions made by human occupants in response to environment. Additionally, zooarchaeological data offer a reflection of past animal availability and use, much of which is at least in part determined by environmental conditions. Here I examine the extent to which …

To Know The Land With Hands And Minds: Negotiating Agricultural Knowledge In Late-Nineteenth-Century New England And Westphalia, Justus Hillebrand

Electronic Theses and Dissertations

Ever since the eighteenth century, experts have tried to tell farmers how to farm. The agricultural enlightenment in Europe marked the beginning of a long arc of new experts aiming to change agricultural knowledge and practice. This dissertation analyzes the pivotal period in the late nineteenth and early twentieth century in Germany and the United States when scientists, improvers, and market agents began to develop comprehensive ways to communicate agricultural innovation to farmers. In a functional approach to analyzing the negotiation of agricultural knowledge through its communication in things, words, and practices, this dissertation argues that the process of change …

Dietary Change Among Canis Familiaris During The Late Ceramic Period On The Maine-Maritime Peninsula: A Case Study From The Holmes Point West Site (Me 62-8), Machias Bay, Maine, Abby E. Mann

Electronic Theses and Dissertations

Archaeological study of Indigenous pasts has been characterized by a focus on objects over people. This study attempts to humanize the past by illuminating human agency in the human-dog relationship through a case study of dog health and diet during the Late Ceramic period (ca. 950 – 450 BP) in the Maine-Maritime Peninsula region. To circumvent the cycle of western knowledge building and marginalization of Indigenous communities, past Wabanaki people and their relationships with dogs are positioned at the center of research questions presented here. Few studies in the Northeast have analyzed dog remains from the Ceramic period (ca. 3050 …

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 …

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. …

The Economic And Social Values Associated With Small South Dakota Lakes, Aaron Patrick Sundmark

Electronic Theses and Dissertations

The valuation of small fishing lakes is a vital component in understanding the importance of fishing and of recreational resources, in general. Knowing the values associated with such lakes is essential when prioritizing management activities. The overall value of a lake as a resource for human benefit is estimated as the summation of both instrumental and non-instrumental values. Instrumental values consist of economic and utilitarian values, as well as the values that a lake provides from ecosystem services. Non-instrumental values consider what the lake is worth as a good of its own, such as aesthetic, moral, and spiritual values gained …

Assessing Economic Performance Of Maine's Lobster Fleet Under Changing Ecosystem Conditions In The Gulf Of Maine, Alexa M. Dayton

Electronic Theses and Dissertations

This research evaluates lobster producer efficiency and considers fleet wide economics and policy implications in support of changing marine ecosystems in the Gulf of Maine. We conducted a comprehensive lobster industry survey to assess costs and effort expended at the producer level for a representative fishing year, and establish a series of production function performance baselines for future comparison. The demographic data, attitudes and valuations collected allow us to characterize the fishing effort and regional dependency on the resource. We look at the Maine Lobster limited entry licensing system, to understand how the future participation in the fishery might change, …

Social Conflict On The Seas: Links Between Overfishing-Induced Marine Fish Stock Declines And Forced Labor Slavery, Jessica L. Sparks

Electronic Theses and Dissertations

Despite media attention detailing labor abuses in fisheries, social-ecological systems research has largely failed to consider whether fish stock declines could be contributing to increases in forced labor slavery. Empirical fisheries data suggests, though not a ubiquitous response to declining stocks, many vessels will fish longer, farther from shore, and deeper in waters to maintain yields. This effort intensification increases production costs, and Brashares et al. (2014), consistent with slavery theory, posited cheap and/or unpaid labor as an approach to offset increasing costs and continue harvesting fish species at a rate otherwise cost-prohibitive.

Therapy Dogs And The Impact On Employees In The Pediatric Medical Setting, Laine Foith

Electronic Theses and Dissertations

More than 40% of nurses reported experiencing significant burnout. Burnout is characterized by disengagement, cynicism, negative views of personal accomplishment and ability, and emotional exhaustion. The healthcare providers that experience burnout can possibly expect a decrease in ability to recognize/report errors, increase of negative feelings toward the patient, and decrease levels of patient satisfaction (Ernest, 2014). One of the ways Schub (2015) suggested to regulate burnout for employees was to provide psychosocial support to colleagues to reduce stress. This study is one of the first attempts to bridge the gap between the unknown correlation between qualitative and quantitative benefits of …

A Comparison Of Land Use And Land Cover In Public Lands Of The Northwestern Great Plains And High Plains Ecoregions And The Implications For Grassland Birds, Dawn L. Siemonsma

Electronic Theses and Dissertations

Loss and degradation of grassland habitat are driving forces that contribute to widespread declines of grassland birds in the United States. Many studies have evaluated habitat needs for the conservation of grassland birds, but the relative contribution of public lands in representing and maintaining avian biodiversity remains poorly understood. Having a better understanding of the role that publicly managed grasslands play in the conservation of grassland bird habitat is important for assessing the value of the investment the American public makes in these lands. Therefore, I investigated spatial relations among variations in amounts and distributions of publicly owned and managed …

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, …

Sources Of Ecologically Important Trait Variation In Mosquitofish (Gambusia Affinis And Gambusia Holbrooki), Heather Ann Arnett

Electronic Theses and Dissertations

The study of contemporary evolution and eco-evolutionary dynamics is classically defined in terms of genetic evolution, but the actual suite of processes driving contemporary trait change is likely much more complex than often credited. This dissertation considers additional mechanisms of trait change that might be important to an emerging model system for study of contemporary evolution and eco-evolutionary dynamics. Specifically, the research focuses on phenotypically plastic and demographic trait variation in Eastern and Western Mosquitofish (Gambusia affinis and G. holbrooki) facing the major ecological gradient of predation risk. Plasticity experiments employed a common-garden rearing design to manipulate fish …

Effects Of Visitors And Enrichments On Behavior Of Captive Red Wolves’ (Canis Rufus) At The Great Plains Zoo, Sioux Falls, South Dakota, Kylee S. Shotkoski

Electronic Theses and Dissertations

Red wolves (Canis rufus) are the first animals to maintain a wild population from captive, released individuals. A captive breeding program for red wolves was started before complete extirpation, and 4 breeding pairs were released in Alligator River National Wildlife Refuge (North Carolina) in 1987 and a small wild population still exists there. Currently, there are several captive breeding facilities for red wolves within the Species Survival Plan (SSP) program. The Great Plains Zoo in Sioux Falls, South Dakota participates in the SSP program. My study was initiated to create a natural history background and evaluate interaction between …

Evaluation Of Bison (Bison Bison) Ecology At The Olson’S Bison Conservation Ranches, Pine River Ranch, Manitoba, Canada, Joshua L. Leonard

Electronic Theses and Dissertations

Bison (Bison bison), the largest mammalian species in North America, historically numbering in the tens of millions (Roe 1970, McHugh 1972, Dary 1989, Shaw 1995), was nearly extirpated at the turn of the 19th century (Knapp et al. 1999; Gates et al. 2010). At the time, estimates of less than 1,000 bison remaining in North America are widely accepted (Hornaday 1889; Seton 1927; Gates et al. 2010). The decline of bison includes factors such as disease (Flores 1991; Isenberg 2000), sport hunting (Danz 1997; Dary 1989; Hewitt 1919; Isenberg 2000; McHugh 1972), and unofficially funded commercial hunting by the U.S. …

An Analysis Of The Interaction Of Methylphenidate And Nicotine In Adolescent Rats: Effects On Bdnf, Elizabeth D. Freeman

Electronic Theses and Dissertations

This investigation was an analysis of the interaction of adolescent exposure to methylphenidate (MPH; trade name: Ritalin) on nicotine sensitization and conditioned place preference (CPP) in a rodent model and underlying mechanisms of this effect. Animals were treated IP with 1 mg/kg MPH or saline using a ―school day‖ regimen of five days on, two days off, from postnatal day (P) 28-50. During the final two weeks of MPH treatment, animals were either behaviorally sensitized to nicotine (0.5 mg/kg free base) or saline for 10 days, or conditioned to nicotine or saline using the CPP behavioral paradigm. In addition, three …

Gentrification And Vulnerability Of Maine Fishing Communities, Cameron R. S. Thompson

Electronic Theses and Dissertations

Maine hosts numerous small fishing villages that contribute greatly to the States economy and culture. The cumulative effects of state and federal regulation, stock depletion and other socio-economic trends threaten these communities. Drawing on ethnographic research and interviews, we examine how gentrification is affecting the vulnerability and resilience of fishing communities. This study has revealed gentrification to be a complex process, which is merely the most readily recognizable symptom of forces that are reshaping the post-industrial landscape. Fishing communities can no longer be thought of as discrete entities isolated from broad social and economic changes. Technology and new markets have …

Two Bioeconomic Studies On Haddock Culture: Live Feed And Juvenile Production, Kate M. Waning

Electronic Theses and Dissertations

The State of Maine is reliant upon its natural resources. Wild catches of marine finfish, especially ground fish such as cod and haddock, are declining. In addition, several new restrictions have been placed on the culture of Atlantic salmon due to its listing under the Endangered Species Act. These issues serve as an impetus to explore the development of alternative species for cold-water marine aquaculture. This research focuses on early haddock culture. The two areas where haddock culture varies from production of other species are the need for live feeds and proximity to seawater. Unlike salmon, haddock spend their entire …

An Armington Model Of The U.S. Demand For Scallops, Fuzhi Cheng

Electronic Theses and Dissertations

The supply of scallops in the United States in recent years has remained relatively stable and the supply source has shifted noticeably from domestic production to imports, especially from China and Japan, where aquaculture production of scallops has been successful. During the past decade, the market share of imported scallops has increased drastically. The scallop fishery in the U.S. is now facing potential competitions from imports. Continuing efforts to provide information on the effect of increasing imports on the U.S. scallop market is warranted. In addition, the impacts of supply increases on domestic scallop prices, either through wild stock enhancement …
